Logging is one of the most important detective controls in application security; insufficient logging and monitoring is recognized as among the most critical security risks in OWASP's Top Ten 2021. Appropriate logs can not only detect malicious activity, but are also invaluable resources in post-incident investigations, can be used to troubleshoot access control and other security related problems, and are useful in security auditing. Though easy to overlook during the initial design and requirements phase, logging is an important component of holistic application security and must be incorporated into all phases of the SDLC. Recommendations for logging include the following Log using consistent, well-defined formats that can be readily parsed for analysis. According to OWASP Top Ten Proactive Controls C9, Apache Logging Services is one example of a project that provides support for numerous languages and platforms Carefully determine the amount of information to log. This should be determined according to the specific application environment and requirements. Both too much and too little logging may be considered security weaknesses (see CWE-778 and CWE-779). Too little logging can result in malicious activity going undetected and greatly reduce the effectiveness of post-incident analysis. Too much logging not only can strain resources and lead to excessive false positives, but may also result in sensitive data being needlessly logged. Ensure clocks and timezones are synchronized across systems. Accuracy is crucial in piecing together the sequence of an attack during and after incident response. Consider incorporating application logs into a centralized log server or SIEM. Attribution: Adapted from OWASP Cheat Sheet Series under CC-BY-SA-4.0.
