File Integrity Monitoring (FIM) is a cybersecurity process that involves continuously monitoring files and systems to identify any unauthorized changes. FIM solutions maintain file integrity by comparing a file or system's current state to a known, trusted baseline and flagging any discrepancies. It is key for identifying security breaches, preventing data tampering, and maintaining compliance.

When outsourcing the IT department was first introduced, many business owners hailed it as the solution to all their technology problems. The promise of reduced headcount, less overhead and sunk costs, as well as reduced management responsibilities, seemed like a gift that would boost profits. When cloud computing entered the business world, the same promises were realized. However, shifting responsibility to an outside administrator brought new risks to the organizations.

Contrary to what one might expect, creating a File Integrity Monitoring (FIM) system is pretty easy. Practically anyone with a modicum of Python, Perl, or development skills can write an app or script to gather a file's checksum, compare it to a list or baseline, and tell you whether or not said file has changed. But creating a good FIM solution is hard. Many inadequate checkbox File Integrity Monitoring solutions are on the market because while detecting change is easy, reconciling it is not.

Protecting mission-critical Linux machines is essential for any business. Sophisticated cyber attacks can start from a low-value target machine and pivot into high-value servers filled with sensitive information. However, many organizations face challenges when their infrastructure includes older Linux kernels that do not support modern tracing technologies.

Integrity is a vital component of any cybersecurity policy, making up one-third of the CIA Triad. However, until recently, the industry has had a limited understanding of the term, using it primarily in the context of data security. Integrity means so much more than this principle alone: it impacts every facet of an information system and can drive an organization's entire security program. Fundamentally, integrity ensures that no one tampers with your assets, whatever and wherever they may be.

Threats to sensitive data are everywhere. From sophisticated cybercriminal syndicates to accidental exposure to nation-state-backed advanced persistent threat (APT) groups and everything in between, it's never been more critical for organizations to have the correct data protection tools.

An insider threat is someone inside an organization – including current and former employees, partners, and contractors – who, intentionally or otherwise, put their organization at risk. They typically abuse their access to private information and privileged accounts to steal or sabotage sensitive data, often for financial gain or even revenge. Organizations today must have effective security solutions in place to identify and respond to insider threats.

A security incident can be the result of a single unauthorised change. A few may say, 'one change is inconsequential, don't sweat the small stuff.' But when it comes to infrastructure security, the detail is of paramount importance! Just a single edit to a single line item can have a negative effect on an entire file or operating system. It's essential to be made aware of any unauthorised file change and to be made aware with haste.

File integrity monitoring (FIM) and endpoint detection and response (EDR) are two cybersecurity solutions that are often foundational aspects of organizations’ security strategies. EDR is implemented in order to stop known and unknown threats at endpoints, often with advanced functions such as behavioral monitoring and analysis, antivirus protection, and threat response capabilities.

Thanks to the burgeoning supply chain, a host of IoT and work-from-home devices, and an expanding cloud presence, organizations are constantly ingesting new hardware into their IT environments. With each new line of code comes a fresh chance for a hidden vulnerability. With each unfound weakness, attackers gain one more opportunity to gain a foothold in the organization and compromise sensitive assets.
