6.2.4Bespoke and custom software are developed securely

Defined Approach Requirements:

Software engineering techniques or other methods are defined and in use by software development personnel to prevent or mitigate common software attacks and related vulnerabilities in bespoke and custom software, including but not limited to the following:

- Injection attacks, including SQL, LDAP, XPath, or other command, parameter, object, fault, or injection-type flaws.

- Attacks on data and data structures, including attempts to manipulate buffers, pointers, input data, or shared data.

- Attacks on cryptography usage, including attempts to exploit weak, insecure, or inappropriate cryptographic implementations, algorithms, cipher suites, or modes of operation.

- Attacks on business logic, including attempts to abuse or bypass application features and functionalities through the manipulation of APIs, communication protocols and channels, client?side functionality, or other system/application functions and resources. This includes cross-site scripting (XSS) and cross-site request forgery (CSRF).

- Attacks on access control mechanisms, including attempts to bypass or abuse identification, authentication, or authorization mechanisms, or attempts to exploit weaknesses in the implementation of such mechanisms.

- Attacks via any "high-risk" vulnerabilities identified in the vulnerability identification process, as defined in Requirement 6.3.1

Defined Approach Testing Procedures:

6.2.4 Examine documented procedures and interview responsible software development personnel to verify that software engineering techniques or other methods are defined and in use by developers of bespoke and custom software to prevent or mitigate all common software attacks as specified in this requirement.
