blogin a previous blog article, we learned how we could utilize samsung wallet's rp sdk in order to verify a user's identity from an android application. in this tutorial, we learn how to verify a user's identity directly from a website using samsung wallet and its web2app api in a spring boot web server. prerequisites the process described has the following prerequisites: a valid us driver's license or state id for the user whose identity is to be verified the samsung galaxy device used needs to be registered for the us region and have mdl support complete the samsung wallet partner onboarding process create a wallet card template with the relying party type in the samsung wallet partners portal implementing the verify with wallet functionality in your website the verify with wallet (vww) process utilizing the web2app method consists of two distinct parts. the "verify with samsung wallet" button. this button contains the vww link with the rp card data tokenized as the cdata. the user can click this vww link to initiate the verification process. the partner server containing the /key and /auth endpoints. the partner server processes the requests sent from the samsung wallet application and handles the complete vww process. frontend configuration in order to initiate the verify with wallet process, we need to implement a "verify with samsung wallet" button in a webpage. implementing the button is a very simple process similar to creating a traditional "add to wallet" button. we can make use of the data transmit link approach and create a button that contains the vww link: https://a.swallet.link/vww/v1/{cardid}#clip?cdata={cdata} replace {cardid} with the id of your own card. meanwhile, the cdata value needs to be generated in real time. this is done using a process similar to generating cdata for atw operation, only with the payload contained being different according to the specification for the relying party card type. check out the sample code for the complete process of cdata generation and using it in the button. backend configuration once the button implementation is complete, you need to configure your server to handle the exchange of information between your server and samsung wallet application. the vww process requires the partner to define 2 api endpoints: /rp/v1.0/{cardid}/{refid}/key: establishes a secure session and prepares the request data for the process. /rp/v1.0/{cardid}/{refid}/auth: processes encrypted authentication data and mdl data received from the wallet application. the workflow for the information exchange is as follows: once the vww button is clicked, the samsung wallet application opens. samsung wallet checks if the device has a driver's license already enrolled in the device. if an mdl already exists on the device, the samsung wallet application calls the /key endpoint to establish a session. after establishing session with the partner server and retrieving the mdoc request, the samsung wallet application prompts the user to confirm if they wish to share their information with the partner. after the user confirms that they wish to proceed, the application finally sends the requested information to the /auth api to complete the vww process. define the /key endpoint when the user clicks the "verify with samsung wallet" button, the samsung wallet application first checks if a driver's license is enrolled. if a license is found, the application generates "device engagement bytes" in accordance with the iso-18013-5 specification. these bytes are then transmitted to the server's /key api endpoint to establish a verification session. the post request body is json with a single field called data. this field value is the jwt containing encrypted device engagement bytes. {"data": "………"} in the /key api endpoint, accept the post request sent to the path /{cardid}/{refid}/key extract the data field from the body as the jwt and decrypt it to receive the device engagement bytes. establish a session using the device engagement bytes. create the mdoc request data and send it back to the samsung wallet application as response to the post request. the complete process is shown below: @postmapping("{cardid}/{refid}/key") fun receivekey( @pathvariable cardid: string, @pathvariable refid: string, @requestbody body: string ): responseentity<string> { val cdata = jsonparser.parsestring(body).asjsonobject.get("data").tostring() val base64engagementbytes = jwtgen.decryptbase64engagement(cdata) val mdoc18013 = createmdoc10813(base64engagementbytes) val cdataresponse = "{\"data\": \"${jwtgen.generaterequestjwt(mdoc18013)}\"}" return responseentity.ok().contenttype(mediatype.application_json).body(cdataresponse) } decrypt the device engagement bytes from the request body the data field value received in the /key api contains the required device engagement bytes encoded in the jwt format. simply decrypt the jwt in order to retrieve the device engagement bytes. here the decryptbase64engagement() function is defined as follows: fun decryptbase64engagement(data: string): bytearray { val signedjwt: signedjwt = signedjwt.parse(data) val payload = signedjwt.payload val jwe = jweobject.parse(payload.tostring()) val partnerprivatekey = keyutil.readprivatekey(partner_private_key) val decrypter = rsadecrypter(partnerprivatekey) jwe.decrypt(decrypter) val base64engagement = jwe.payload.tojsonobject().get("data").tostring() val base64engagementbytes = base64.geturldecoder().decode(base64engagement) return base64engagementbytes } simply perform the jwt decryption operation using your private key to get the decrypted jwe payload in the json format. in the json-formatted payload, the data field contains the device engagement bytes encoded in the base64url string format. decode the string using a base64url decoder and you get the final device engagement bytes. create a shared session using device engagement bytes the createmdoc10813(base64engagementbytes) function creates a shared session between the /key api and /auth api using a companion object. having a shared session between the two endpoints is mandatory in order to decrypt the information provided by the samsung wallet application later on. inside the companion object, we also need to generate an elliptic curve keypair in order to establish the encrypted session. the companion object is defined as shown below: companion object{ val keypair = keyutil.generateeckeypair() var mdoc18013: mdoc18013? = null fun createmdoc10813(base64engagementbytes: bytearray): mdoc18013 { if (mdoc18013 == null ) { mdoc18013 = mdoc18013(keypair, base64engagementbytes ) return mdoc18013!! } else{ return mdoc18013!! } } fun getmdoc10813(): mdoc18013 { return mdoc18013!! } } the elliptic curve keypair is generated using a simple keypairgenerator class instance. fun generateeckeypair(): keypair { val keypairgenerator = keypairgenerator.getinstance("ec") val ecgenparameterspec = ecgenparameterspec("secp256r1") keypairgenerator.initialize(ecgenparameterspec) return keypairgenerator.generatekeypair() } prepare the mdoc request data preparing the mdoc request data is the most crucial part of the vww operation. the request data defines the data that needs to be retrieved from mdl. the generaterequestjwt() function can be divided into several parts: define and encode the request data payload. encrypt the device request. create session establishment data using the encrypted device request bytes. create a signed jwt. below, we go through these steps one at a time. define the request data payload and encode it to a cbor byte array // define requested data fields val requestdata = """ { "doctype": "org.iso.18013.5.1.mdl", "namespaces": { "org.iso.18013.5.1": { "family_name": true, "age_in_years": true, "issue_date": true, "expiry_date": true, "document_number": false, "issuing_authority": false }, "org.iso.18013.5.1.aamva": { "dhs_compliance": false } } } """.trimindent() // cbor encoding process with tagging val firstencoded = cborobject.fromjsonstring(requestdata).encodetobytes() val thirdencoded = cborobject.fromobjectandtag(firstencoded, 24).encodetobytes() val itemrequestbyteslist = listof(thirdencoded) // create mdoc items requests array val docrequestsarray = cborobject.newarray() itemrequestbyteslist.foreach { val docrequest = cborobject.newmap() docrequest.set("itemsrequest", cborobject.decodefrombytes(it)) docrequestsarray.add(docrequest) } // create device request using docrequestarray val devicerequest = cborobject.newmap() devicerequest.set("version", cborobject.fromobject("1.0")) devicerequest.set("docrequests", docrequestsarray) encrypt the device request val encrypteddevicerequestbytes = mdoc18013.encryptdevicerequest(devicerequest.encodetobytes()) create session establishment data using the encrypted device request bytes val establishment = cborobject.newmap() establishment.set("ereaderkey", cborobject.fromobjectandtag(mdoc18013.getereaderkey(),24)) establishment.set("data", cborobject.fromobject(encrypteddevicerequestbytes)) val establishmentstring = base64.geturlencoder().encodetostring(establishment.encodetobytes()) create a signed jwt using the establishmentstring as the jwe payload val jweobj = jweobject(jweheader.builder(jwealgorithm.rsa_oaep_256, encryptionmethod.a128gcm).build(), payload(establishmentstring)) val encryptor = rsaencrypter(samsungpublickey as rsapublickey) jweobj.encrypt(encryptor) val jwsheader = jwsheader.builder(jwsalgorithm.rs256) .contenttype("auth") .customparam("partnerid", "412255212345678910") .customparam("certificateid", "a123") .customparam("ver", "3") .customparam("utc", system.currenttimemillis()) .build() val jwsobj = jwsobject(jwsheader, payload(jweobj.serialize())) val rsajwk = rsakey.builder(partnerpublickey as rsapublickey).privatekey(partnerprivatekey).build() val jwssigner = rsassasigner(rsajwk) jwsobj.sign(jwssigner) return jwsobj.serialize() now, we can send this jwt back as the response from the /key api. if everything is done properly, the samsung wallet application should receive the verification request along with the list of requested fields. after processing and verifying the request, the samsung wallet application needs to prompt the user to verify their identity. once the user verifies their identity using the application, it sends the requested information back to the /auth api endpoint. next, let's define the /auth api endpoint to retrieve the requested information. define the /auth api endpoint similar to the previously defined /key api endpoint, the /auth api endpoint also receives a single json payload with a single field called data, which contains the requested information in a jwt encoded format. {"data": "………"} decrypt the jwt payload from the request body we can extract the data field and decrypt the jwt following the same process used in the /key api. @postmapping("{cardid}/{refid}/auth") fun receiveauth( @pathvariable cardid: string, @pathvariable refid: string, @requestbody body: string ): httpstatus { val responsedata = jsonparser.parsestring(body).asjsonobject.get("data").tostring() val signedjwt: signedjwt = signedjwt.parse(responsedata) val payload = signedjwt.payload val jwe = jweobject.parse(payload.tostring()) val partnerprivatekey = jwtgen.partnerprivatekey val decrypter = rsadecrypter(partnerprivatekey) jwe.decrypt(decrypter) // process and decrypt the data until the requested information is retrieved return httpstatus.ok } after the decryption operation, we get another json object in the decrypted jwe payload. in this json payload, the data field contains the encoded data of the information we requested. to decode and decrypt this data: decode the extracted data field value using base64url decoder. this gives us the encrypted mdoc response in a cbor byte array. decode the cbor object from the byte array and get the mdoc data from the data field. decrypt the mdoc data using the mdoc18013.decryptmdocresponse() function to retrieve the plain response in the json format. warningthe mdoc18013 instance used for this step must be the same instance used in the /key api. otherwise, the decryption operation fails. val mdoc18013 = getmdoc10813() val cbordata = jwe.payload.tojsonobject().get("data").tostring() val decodeddata = base64.geturldecoder().decode(cbordata) val mdocresponse = cborobject.decodefrombytes(decodeddata) val mdocdata = mdocresponse.get("data") val decryptmdocresponsebytes = mdoc18013.decryptmdocresponse(mdocdata.getbytestring()) val plainresponse = cborobject.decodefrombytes(decryptmdocresponsebytes).tojsonstring() after these steps, we finally have the mdoc response in a plain json format. { "status": 0, "version": "1.0", "documents": [ { "doctype": "org.iso.18013.5.1.mdl", "devicesigned": {}, "issuersigned": { "issuerauth": ["......."], "namespaces": { "org.iso.18013.5.1": [ "pghkawdlc3rjrbkhfwzyyw5kb21uczc4zny4c2nongmyzhr5mnlyotzxzwxlbwvudelkzw50awzpzxjsywdlx2lux3llyxjzbgvszw1lbnrwywx1zrgs", "pghkawdlc3………" ], "org.iso.18013.5.1.aamva": [

org.iso.18013.5.1.aamva are the fields we initially requested in the key api. simply decode these cbor-encoded fields to retrieve the information you requested. for example, the "pghkawdlc3rjrbkhfwzyyw5kb21uczc4zny4c2nongmyzhr5mnlyotzxzwxlbwvudelkzw50awzpzxjsywdlx2lux3llyxjzbgvszw1lbnrwywx1zrgs" value informs us that element name is age_in_years and its value is "44," meaning the subject is 44 years old. we can extract the rest of the requested information by decoding the other provided values in the same way. figure 1: verifying user identity using vww web2app process summary in this tutorial, we learned how we can implement user identity verification on a website utilizing samsung wallet's verify with wallet functionality. by making use of the web2app method

to create business account and agree to the terms and conditions the partners complete the company profile information to onboard, create and manage business in wallet partner here’s a step-by-step guide for a new partner to sign up for the samsung wallet partners portal create business account - to use the wallet partners portal, one must create business account to get started, one must have a samsung developer business account this account is required to manage company’s digital assets and integrate services with samsung wallet accept the terms and conditions - to use wallet partners portal, review and accept the terms and conditions of the samsung developer portal ensure to read through the guidelines carefully, as they outline the rules for integrating business with samsung wallet verify account profile – complete the company profile information then enter the company name, company website, username etc additional information for the business account is optional, but providing detailed information will help with the registration process after filling out the required details, click submit to send the registration form for review welcome onboard - once the business account is created and the information is submitted; the wallet partner onboarding process is complete after completing the onboarding process, a welcome email confirming that the business has been successfully registered with the samsung wallet partners portal set encryption information and request permission setting encryption information involves configuring security measures to protect sensitive data during transactions and interactions within the samsung wallet partners portal encryption is used to secure the data being exchanged, preventing unauthorized access or interception once the encryption information is configured, one will need to request permission to access specific services within the samsung wallet partners portal permissions are necessary for performing operations such as adding or managing digital assets e g , cards, tickets, loyalty programs and accessing sensitive business data few points to remember only one account allowed per company manage the cards with one account for partners, one can only manage cards registered with the account multiple users with one account at same time is not allowed if someone else is signed in with the same account, the account in use will be signed out steps to set encryption information we need to perform encryption authentication to use the wallet partners portal create a csr that will request a digital certificate to be issued by a trusted authority we support multiple csr registrations if you click the + button, the csr registration area will be added if you click the - button, the csr registration area will be deleted go to the wallet partners portal and input the csr registration details item description encryption type select end to end encryption csr or none upload later csr csr certificate signing request the samsung public key is the key used for data encryption this can be used to issue and delete wallets csr is a file used to request signature of a certificate after uploading csr to the portal, csr will be signed using the samsung certificate please be careful not to expose samsung public key and csr due to security issues upload a * csr file only none upload later you need to set the encryption information csr to utilize the full functionality of samsung wallet service even if the subscription is done, you must upload the csr file later samsung public key samsung public key is sent to the partner’s email account signed certificate the signed certificate is sent to the partner’s email account complete encryption authentication to verify the correctness of the setup click done to submit the encryption information and complete the process a welcome email is sent when a user completes the sign-up process in addition, information required for the completion of csr is sent along with it upon registering a csr, 2 certificates will be issued certificates are provided by email or direct download one is the jws certificate, which is the partner-provided csr signed by samsung wallet, the other is the jwe certificate, which is self-signed by samsung wallet to distinguish between jwe and jes certificates, the jws certificate will have the same filename as the 'certificate name' entered by the partner the jwe certificate self-signed by samsung wallet will include 'walletsvc samsung com' in its filename security factors security factors refer to the various protocols and measures taken to secure the data and ensure the privacy and safety of the partners the service flow describes the series of steps or actions taken to complete a specific task in the wallet partners portal, from initial account creation to the use of services the service flow also ensures that data is handled securely csr certificate signing request process overview the certificate signing request csr process is critical for requesting a digital certificate from a certificate authority ca openssl, an open-source command-line tool, is commonly used to create the necessary files for csr generation and private key creation, which are essential to establish secure communication private key private key helps to enable encryption and is the most important component of certificates the private key should remain secure, as it is used for signing the csr and encrypting communication openssl genpkey -out domain key -algorithm rsa -pkeyopt rsa_keygen_bits 2048 note-if you want to make the private key more secure, adding ‘-des3’ on the command encrypts it with a password creating a certificate signing request the csr contains the public key and additional information such as the organization’s details this is required when a digital certificate is to be signed by a trusted certificate authority ca steps to create a csr from an existing private key open a terminal and use openssl to generate a csr domain csr using the existing private key openssl req -out domain csr -key domain key -new -sha256 it will also prompt you to provide csr information, such as a country name c the two-letter country code e g , us for the united states b state or province name st your state or province c locality name l your city or locality d organization name o your organization’s legal name e organizational unit ou optional the department or business unit within the organization f common name cn the domain name e g , www yourdomain com g email address email your contact email address you are about to be asked to enter information that will be incorporated into your certificate request what you are about to enter is what is called a distinguished name or a dn there are quite a f ew fields but you can leave some blank for some fields there will be a default value, if you enter ' ', the field will be left blank ----- country name 2

docapplication security this topic describe the security of applications which run on samsung devices related info web security testing guide owasp secure software development lifecycle microsoft security development lifecycle sdl cwe list version 4 6 overview security is becoming an important issue with the increase of various smart devices in order to protect data from users and businesses, samsung devices are enhancing security in several layers, from hardware to software as samsung device applications are also software driven by samsung, the security needs to be taken into account samsung device applications can store important information such as code and key values and personal information of the user, which is an important resource that must be protected these resources can be leaked due to a variety of reasons, such as a simple mistake by a developer or hacking by an attacker in order to safeguard this, samsung device applications need to be developed according to secure by design in particular, the personal information of the user should comply with the policy related to the personal information for each country secure by design all software within the devices developed by samsung are based on the secure development lifecycle sdl model, and development step is divided into analysis, design, implementation, and testing, so vulnerability should be removed by performing a security review at each step from the same point of view, applications operating on samsung device should maintain the same security level for this, we recommend that you consider security in the application development phase by referring to the following step-by-step security review security in the analysis/design phase you should identify important information that is stored and transferred and ensure that the information is handled safely if you receive user input, you should review that you do not require more information than you need, and there is no issue with the input format you must identify the important information to be used and ensure that the information is displayed on vulnerable areas in the flow of the program in particular, when transmitting important information outside the device, you need to ensure that it communicates with the specified server through a secured channel at the time of designing, you must first define important information that needs to be protected and design it in a proper manner to protect it security in the implementation phase it must be implemented in compliance with security rules to prevent information in the software from being leaked through known vulnerabilities important information obtained in the design phase should be stored by applying security techniques such as encryption and make sure that it does not exist in plain text within the program establish secure coding rules for each language and proceed with development accordingly you must use only the minimum permissions required and notify the user of the permissions you use you should make sure that the security channel is properly set on the network, and the latest version of the technology is applied if you use encryption algorithms, you must use them securely using verified standard algorithms where vulnerabilities are not reported security in test phase security checks must be performed before deployment to prevent security issues and maintain security through maintenance after deployment before deployment, it is necessary to verify that there is no issue with analysis, design, and implementation when actually operated through simulated hacking, packet checking, etc after deployment, if a new vulnerability is found or a modification occurs in the security check, it must be patched and applied to all users as soon as possible security review process in order to maintain the security of the application ecosystem, samsung is performing security checks on the submitted applications samsung checks the risk or misuse cases that may occur due to the submitted applications, and if there is an issue, the deployment process can be stopped and the application submitter can be advised to fix it application security guide this section provides basic security guidelines to consider in the development of applications for a safe and reliable application running environment, we recommend that you proceed with the following points in the development phase data protection three key factors for data protection are confidentiality, integrity, and availability if an application sends or stores sensitive information, the application must encrypt data stored on these devices and protect it from attackers it is very important to protect sensitive data such as user credentials or personal information in application security if the mechanism of the operating system is not used correctly, sensitive data can be unintentionally exposed definition of sensitive data personally identifiable information that can be exploited for identity theft for example, resident registration number, social security number, credit card number, bank account number, health information, etc sensitive data that can lead to loss of honor and loss of money if leaked all data that must be protected for legal or compliance reasons security item description data protection sensitive data, such as passwords or pin data, should not be exposed through the user interface the key values used by the application must be hardcoded or not stored in plain text sensitive data should not be stored in an application container or external storage sensitive data should not be recorded in the application log sensitive data should not be shared with third parties unless it is necessary in the architecture sensitive data should not be shared with third parties unless it is necessary in the architecture keyboard cache must be disabled from the text input that processes sensitive data sensitive data should not be exposed even during internal communication you should ensure that the data stored in the client-side storage ex html5 local storage, session store, indexeddb, regular cookie, or flash cookie does not contain sensitive data make sure that you have provided clear t&c for the collection and use of the provided personal information and that you have provided selective consent to the use of that data

docapplication security this topic describe the security of applications which run on samsung devices related info web security testing guide owasp secure software development lifecycle microsoft security development lifecycle sdl cwe list version 4 6 overview security is becoming an important issue with the increase of various smart devices in order to protect data from users and businesses, samsung devices are enhancing security in several layers, from hardware to software as samsung device applications are also software driven by samsung, the security needs to be taken into account samsung device applications can store important information such as code and key values and personal information of the user, which is an important resource that must be protected these resources can be leaked due to a variety of reasons, such as a simple mistake by a developer or hacking by an attacker in order to safeguard this, samsung device applications need to be developed according to secure by design in particular, the personal information of the user should comply with the policy related to the personal information for each country secure by design all software within the devices developed by samsung are based on the secure development lifecycle sdl model, and development step is divided into analysis, design, implementation, and testing, so vulnerability should be removed by performing a security review at each step from the same point of view, applications operating on samsung device should maintain the same security level for this, we recommend that you consider security in the application development phase by referring to the following step-by-step security review security in the analysis/design phase you should identify important information that is stored and transferred and ensure that the information is handled safely if you receive user input, you should review that you do not require more information than you need, and there is no issue with the input format you must identify the important information to be used and ensure that the information is displayed on vulnerable areas in the flow of the program in particular, when transmitting important information outside the device, you need to ensure that it communicates with the specified server through a secured channel at the time of designing, you must first define important information that needs to be protected and design it in a proper manner to protect it security in the implementation phase it must be implemented in compliance with security rules to prevent information in the software from being leaked through known vulnerabilities important information obtained in the design phase should be stored by applying security techniques such as encryption and make sure that it does not exist in plain text within the program establish secure coding rules for each language and proceed with development accordingly you must use only the minimum permissions required and notify the user of the permissions you use you should make sure that the security channel is properly set on the network, and the latest version of the technology is applied if you use encryption algorithms, you must use them securely using verified standard algorithms where vulnerabilities are not reported security in test phase security checks must be performed before deployment to prevent security issues and maintain security through maintenance after deployment before deployment, it is necessary to verify that there is no issue with analysis, design, and implementation when actually operated through simulated hacking, packet checking, etc after deployment, if a new vulnerability is found or a modification occurs in the security check, it must be patched and applied to all users as soon as possible security review process in order to maintain the security of the application ecosystem, samsung is performing security checks on the submitted applications samsung checks the risk or misuse cases that may occur due to the submitted applications, and if there is an issue, the deployment process can be stopped and the application submitter can be advised to fix it application security guide this section provides basic security guidelines to consider in the development of applications for a safe and reliable application running environment, we recommend that you proceed with the following points in the development phase data protection three key factors for data protection are confidentiality, integrity, and availability if an application sends or stores sensitive information, the application must encrypt data stored on these devices and protect it from attackers it is very important to protect sensitive data such as user credentials or personal information in application security if the mechanism of the operating system is not used correctly, sensitive data can be unintentionally exposed definition of sensitive data personally identifiable information that can be exploited for identity theft for example, resident registration number, social security number, credit card number, bank account number, health information, etc sensitive data that can lead to loss of honor and loss of money if leaked all data that must be protected for legal or compliance reasons security item description data protection sensitive data, such as passwords or pin data, should not be exposed through the user interface the key values used by the application must be hardcoded or not stored in plain text sensitive data should not be stored in an application container or external storage sensitive data should not be recorded in the application log sensitive data should not be shared with third parties unless it is necessary in the architecture sensitive data should not be shared with third parties unless it is necessary in the architecture keyboard cache must be disabled from the text input that processes sensitive data sensitive data should not be exposed even during internal communication you should ensure that the data stored in the client-side storage ex html5 local storage, session store, indexeddb, regular cookie, or flash cookie does not contain sensitive data make sure that you have provided clear t&c for the collection and use of the provided personal information and that you have provided selective consent to the use of that data before you use it reference links european union general data protection regulation gdpr overvieweuropean union data protection supervisor - internet privacy engineering networkapplication development privacy guide table 1 data protection security description and reference links authentication if there is a feature to log-in to the remote service by the user, it must be configured through security design even when most of the logic is operating on a remote service, the device must also meet security requirements on how to manage user accounts and sessions security item description authentication if the application provides remote services to the user, user name and password authentication must be performed from the remote service if you use status storage session management, the remote service must authenticate the client request using the randomly generated session identifier without sending the user's credentials if using stateless token-based authentication, the remote services must provide signed tokens using security algorithms when a user logs out, the remote service must end the existing session table 2 authentication security description access control an application can access a resource only if it has access to it security item description access control application must require only the minimum access required application must use the privilege that match the permissions and specify the privileges used when accessing user data, make sure that the principle of minimum access privilege requirement is followed applications must have access to apis, data files, urls, controllers, directories, services, and other resources with minimal access required you should verify and process all input from external resources and users this should include data received through the ui, a user-defined url, inter-process communication ipc , etc if an application uses a completely unprotected custom url, you should not export sensitive information important data or apis must be protected from user access other than data owners reference links owasp cheat sheet access control table 3 access control security description and reference links communications when the network is used, the application should not display the transmitted/received content using a secured channel security item description communications data must be encrypted on the network using tls transport layer security security channels must be used consistently throughout the application the setting of the security channel must be configured to protect information safely the data being transmitted must be protected from being snatched/taken over in the middle ex defence against man in the middle attack reference links owasp – tls cheat sheet table 4 communications security description and reference links input validation you must defend the command insertion attack through validating the validity of input value input value validation should be considered at all stages of development security item description input validation input values must process the data based on type and content, applicable laws, regulations and other policy compliance, and define how to handle it you must ensure that input validation is performed on a trusted service layer you need to check whether it protects against parameter attacks such as mass parameter allocation attacks or unsafe parameter allocation all possible input values e g html form fields, rest requests, url parameters, http headers, cookies, batch files, rss feeds, etc must be checked using validation ex whitelist you should check whether the values entered are in the correct form in well-defined schemas, including allowed characters, lengths, and patterns the url redirection and forward should display a warning that only whitelist targets are allowed or that you are connecting with potentially untrusted content make sure you use memory safety strings, secure memory copy, and pointer calculation to detect or prevent stacks, buffers, or heap overflows in order to prevent integer overflow, you need to make sure that sign, range, and input validation techniques are used reference links xml external entity xxe prevention cheat sheetreducing xss by way of automatic context-aware escaping in template systems table 5 input validation security description and reference links password management in case of application with different user password, security settings are required for them security item description password management you must ensure that the password does not contain spaces and cut/copy is not performed in the password change feature, you should check that the user's current password and new password are required it is recommended to provide a password strength meter so that users can set a stronger password it is also recommended to provide rules that limit allowed character types uppercase letter, numeric, special characters you should check that it is recommended to change your user password within the right due date do not store the user password in the application's properties or settings file in plain text or recoverable form passwords must be stored, transferred, and compared in a hashed state using a standard hash function to prevent random attacks, you should use the login limit number of login or captcha default password should not be generated make sure you do not show the key information, like passwords in the log reference links cwe-804 guessable captchacwe-836 use of password hash instead

description and reference links session manager a session is a technique for controlling and maintaining the status of a user or device interacting with one user in a web application a session has a unique value for each user and cannot guess or share that value security item description session manager you should check that the session token is not exposed/displayed in the application's url parameter or error message make sure the application generates a new session token from user authentication you should check that the session token is stored using properly secured cookies or security methods you should check that a session token is generated using a standard encryption algorithm make sure the session is not reused by verifying that the session token is invalid when logout and session expires reference links owasp session management cheat sheetalgorithms, key size and parameters report 2014 table 7 session manager security description and reference links error handling the purpose of error handling is to allow applications to provide security events related to monitoring, status check, and increase in permission, and not just creating logs security item description error handling you must ensure that common error handling formats and access method are used you must make sure exception handling is used on the code base to explain expected and unexpected error conditions you must ensure that other error handlers that can prepare all unprocessed exceptions are defined in case of an error, you must make sure that the message shown to the user does not contain application-related technical or sensitive information we recommend using separate error codes for error support table 8 error handling security description release check the following before releasing the application security item description release application must be signed and distributed with a valid certificate, and the private key must be properly protected debugging code and
