Peer code reviews are an essential part of the software development lifecycle (SDLC) process, as they help to improve the quality, security, and maintainability of the code. Peer code reviews involve having other developers review the code written by a developer before it is merged into the main branch or deployed to production. Peer code reviews can help to identify and fix errors, bugs, vulnerabilities, performance issues, coding standards violations, design flaws, and other issues that may affect the functionality or usability of the software. Peer code reviews also facilitate knowledge sharing, collaboration, and feedback among the development team, which can enhance the skills and productivity of the developers123.
The other options are not as likely to be included in the SDLC process, as they are either performed at different stages or not directly related to the development of the software. Scheduling the frequency of automated vulnerability scans and defining the scope of annual penetration tests are more related to the security testing and monitoring of the software, which are usually done after the development phase or as part of the maintenance phase. Scanning for data input validation in production is also a security measure that is done after the software is deployed, and it is not a good practice to rely on production testing alone, as it may expose the software to potential attacks or data breaches. Data input validation should be done during the development and testing phases, as well as in production123. References:
