Guide for Error Handling and Logging in CompTIA Security Plus

Error Handling and Logging are key components in the realm of application security. Being a part of the CompTIA Security Plus, their understanding is crucial.
Why Is It Important?
Error Handling and Logging are vital for identifying, debugging, and fixing system errors while maintaining the application secure. Errors, if not correctly handled and logged, can lead to various security vulnerabilities including information leakage, denial of service, etc.

2. Logs should record all necessary information but must also protect sensitive data.
3. Ensure you've practical insights into different error handling and logging techniques for different scenarios, as context-specific questions often come up in CompTIA Security Plus exams.
In summary, comprehending Error Handling and Logging helps maintain application security by preventing unplanned program behavior and recording useful debugging or auditing information.
