4.1.8 Secure Coding
Secure coding is a fundamental pillar in building information systems that are resilient to cyberattacks. Secure coding refers to software development practices that systematically take security into account from the app design phase to implementation and maintenance. This approach aims to prevent various types of vulnerabilities commonly exploited by attackers, such as injection, buffer overflow, cross-site scripting (XSS), insecure deserialization, and improper authentication. In the context of strengthening application security posture, the implementation of secure coding cannot be separated from a structured application security testing process. Two key and complementary approaches in this regard are: 1. Static Application Security Testing (SAST) SAST is a security testing method performed statically on the source code, before the application is executed. It enables in-depth analysis of the source code or bytecode to identify potential security vulnerabilities such as unvalidated input, use of insecure functions, or improper authentication handling SAST is highly effective when applied in the early stages of development because it: a. Provides early feedback to developers 9 , b. Reduces the cost of fixing vulnerabilities early (shift-left security), c. Ensures compliance with established coding standards.
