Garbage collection

Garbage collection is an automated memory management mechanism used in modern programming languages such as Java, Python, C#, and Go. It systematically identifies and reclaims blocks of memory that were previously allocated by a program but are no longer referenced or reachable by any active part of the application. By automating this process, developers are relieved from the complex and error-prone task of manual memory deallocation.

From a security perspective, garbage collection plays a critical role in mitigating common memory-related vulnerabilities such as memory leaks, dangling pointers, and double-free errors. These flaws, if left unaddressed, can lead to application instability, performance degradation, or exploitable security weaknesses frequently leveraged by attackers for arbitrary code execution. By preventing memory corruption at the runtime level, garbage collection strengthens the overall stability, reliability, and security posture of software systems.
