Identifying weaknesses within the IT infrastructure FIM greatly enhances the organization’s ability to detect an attack that may be missed by other security measures. However, FIM tools can still detect such modifications because it reviews the current file against a baseline, as opposed to simply reviewing the file logs.Įxpediting threat detection, response and remediationīy detecting a threat early in the cyber kill chain, the organization stands a better chance of stopping the breach before significant or costly damage is done. Very sophisticated attackers may even alter the log files to cover their activity. In the early stages of a complex cyberattack, cybercriminals may need to alter critical files related to the OS or applications. Some common use cases for a file integrity management tool include: It also helps identify potential security issues more quickly and improves the accuracy of remediation efforts by the incident response team.
The rapid acceleration of remote work due to the COVID-19 pandemic, as well as an explosion of IoT devices has dramatically expanded the attack surface for cybercriminals, thus providing many points of access for these actors.įIM provides an important layer of protection for sensitive files, data, applications and devices by routinely scanning, monitoring and verifying the integrity of those assets. Left undetected, these hackers can steal data, IP, and customer information or otherwise disrupt business operations. In recent years, cybercriminals have become increasingly sophisticated in their use of malware and other techniques to alter critical system files, folders, registries and data end endpoints to carry out advanced cyberattacks. Why is File Integrity Monitoring Important?
In both cases, the FIM tool compares the current file with a baseline and triggers an alert in the event the file has been altered or updated in a way that violates the company’s predefined security policies.

File integrity monitoring (FIM), sometimes referred to as file integrity management, is a security process that monitors and analyzes the integrity of critical assets, including file systems, directories, databases, network devices, the operating system (OS), OS components and software applications for signs of tampering or corruption, which may be an indication of a cyberattack.įIM tools rely on two different verification methods to verify the integrity of critical file systems and other assets: reactive or forensic auditing and proactive or rules-based monitoring.
