Insufficient Logging and Monitoring is a category identified by the OWASP Top 10 list, highlighting the absence of best practices that could prevent or mitigate security breaches. OWASP is dedicated to enhancing software and internet security, and this category emphasizes the importance of properly logging events, storing logs securely, and taking timely action on warnings. Although the prevalence of this vulnerability is based on industry surveys rather than exact data, improving logging and monitoring is universally acknowledged as vital. The impact of inadequate logging is significant, as evidenced by the 2016 average detection rate for attacks being 191 days, allowing attackers to further infiltrate systems and exploit stolen data. Notably, Yahoo's breaches in 2013 and 2014, reported only in 2016, underscore the consequences of delayed breach disclosure. Detecting insufficient logging and monitoring from an outsider's perspective is challenging, but tools like Detectify can simulate attacks to validate logging efficacy. To address these issues, it is crucial to back up logs, ensure sensitive actions are logged, regularly review critical logs, and implement automated alerts for specific warnings.
