Application security monitoring is the practice of monitoring and analyzing applications or software systems to detect vulnerabilities, identify threats, and mitigate attacks. During the development stage, vulnerabilities can arise when developers use third-party open-source code or make an error in application logic.

Controlling complexity is.” That brings me to my main point.
