Common Pitfalls
1
Failing to regularly update and customize audit rules can lead to missed security vulnerabilities.
Organizations may overlook specific risks unique to their environment if they rely solely on default rules, making it crucial to tailor these checks to address their specific security needs.
2
Neglecting to monitor all AWS accounts can result in untracked changes that pose security risks.
In large organizations with multiple AWS accounts, it's essential to ensure that Security Monkey is configured to monitor all relevant accounts to maintain comprehensive visibility and security oversight.
