When understood and employed correctly, file integrity monitoring (FIM) is a critical tool against the compromise of any sensitive information, such as cardholder data breach. One of the most important aspects of initially setting up FIM is to ensure critical log messages are received, detected, communicated to the appropriate administrator, and properly archived. Each unique server in your network requires a file integrity baseline that describes the configuration's standard secure state in comparison to a given file integrity policy. Addressing compliance requirements of various standards including PCI DSS, HIPAA, etc. Following file types should be carefully monitored across the environment: On Linux, the critical directories include: In Linux systems applications are present in: Security and integrity of files are necessary to avoid data breaches.

Do you have a clear picture of how your existing infrastructure is organized? On the other hand, if the servers involve similarly configured web servers yet with different applications running on top of them, consider adding an application identifier to the server group name. These includes uploads and temporary directories as well as log files. It collects and retains logs on all system changes and it stores these logs securely in the CimTrak database to protect them from unauthorized modification. This blog post highlights best practices to efficiently deploy and configure your file integrity monitoring solution.
FIM validates files by comparing the latest versions to trusted versions of these files; then identifies the unexpected and unauthorized changes to make sure if the file has been modified. Verifying Update Status and Monitoring System Health You can check if files have been patched to the latest version by scanning installed versions across multiple locations and machines with the post-patch checksum.

Too many files can hamper analysis whereas too few can result in loss of crucial data that can help in identifying a security event.

By narrowing down your file and directory targets when creating policies, your FIM becomes more efficient in detecting changes. File integrity monitoring simplifies forensics by helping you zero in on the errant change, so you can roll it back or take other remediation. What operating systems and versions need to be monitored? Who will manage and administer the system. Its research is produced independently by its research organization without input or influence from any third party.
