To create a secure digital profile, organizations need digital integrity. This principle encapsulates two things. First, it upholds the integrity of files that store operating system and application binaries, configuration data, logs and other crucial information. Second, it protects system integrity to make sure applications, endpoints and networks perform their intended functions without degradation or impairment.
Healthcare organizations continue to face relentless cyberattacks owing to the immense value placed on patient health information on the dark web. Patient records have almost everything the attacker needs to carry out sophisticated insurance fraud schemes, purchase medical supplies or drugs, or commit other types of fraud including outright identity theft.
If you’ve been in information security for a while, you’ve likely had some experience with file integrity monitoring (FIM). It’s a capability with a long history, going back to the original open-source Tripwire tool for monitoring file hashes. And FIM has staying power. It’s still around, and there are still new deployments. There aren’t a lot of security controls that continue to be valuable over such a long time frame.
In a previous article, I noted that organizations are witnessing a surge in integrity-based attacks targeting their networks. Enterprises can defend themselves against these types of threats by turning to the National Institute of Standards and Technology (NIST) Cybersecurity Framework. They can then pair the risk-based approach with NIST SP 800-53 and other security control catalogs that enable integrity management.
