File Integrity Monitoring (FIM) is an IT safety management that displays and detects file adjustments in laptop methods. It helps organizations audit vital recordsdata and system configurations by routinely scanning and verifying their integrity. Most data safety requirements mandate using FIM for companies to make sure the integrity of their information.
IT safety compliance includes adhering to relevant legal guidelines, insurance policies, laws, procedures, and requirements issued by governments and regulatory our bodies similar to PCI DSS, ISO 27001, TSC, GDPR, and HIPAA. Failure to adjust to these laws can result in extreme penalties similar to cyber breaches, confidential information loss, monetary loss, and reputational harm. Subsequently, organizations should prioritize adherence to IT laws and requirements to mitigate dangers and safeguard their data methods successfully.
The speedy tempo of technological development and a scarcity of expert cybersecurity professionals contribute to compliance difficulties. To successfully meet these laws, companies must strategically plan, allocate assets to cybersecurity efforts, and completely classify and shield their information property.
Advantages of complying with cybersecurity requirements
Compliance with cybersecurity laws and requirements is vital for companies of all sizes. These laws require implementing particular cybersecurity measures, insurance policies, and processes. By adhering to those requirements, organizations make sure the transparency and integrity of their cybersecurity practices. Some advantages embody:
- It ensures that organizations have resilient backup and restoration procedures in place. This minimizes disruptions to enterprise operations and maintains continuity throughout a cyber incident or catastrophe, as information saved in backup websites will be restored.
- It supplies a structured framework for managing dangers throughout varied enterprise points. Organizations can scale back the prices related to cybersecurity incidents and regulatory non-compliance by following established procedures and controls.
- It safeguards a company’s fame. Information breaches can considerably affect an organization’s fame. Compliance helps shield towards such breaches, thereby safeguarding the enterprise’s fame.
- It facilitates entry into regulated markets. In healthcare, finance, and retail sectors, it assures regulators that the agency’s IT practices and methods meet the mandatory requirements.
The Wazuh FIM functionality
Wazuh is an open supply safety answer that provides unified XDR and SIEM safety throughout a number of platforms. It protects workloads throughout on-premises, virtualized, cloud-based, and containerized environments to offer organizations with an efficient strategy to cybersecurity. Wazuh affords file integrity monitoring (FIM) as one among its capabilities; it additionally supplies different capabilities, similar to safety configuration evaluation and menace detection and response.
The Wazuh FIM functionality ensures the next:
- Actual-time and scheduled file and listing monitoring.
- Detection of unauthorized file adjustments.
- Particulars about what or who made adjustments to information.
FIM, mixed with different Wazuh capabilities similar to malware detection, vulnerability detection, and Safety Configuration Evaluation (SCA), enhances menace detection, investigation, and remediation. These capabilities will help streamline your group’s safety compliance efforts.
Making certain regulatory compliance utilizing the Wazuh FIM functionality
Customers can configure file integrity monitoring to satisfy the necessities of IT safety compliance requirements related to their group. The Wazuh FIM will be configured to observe file addition, deletion, and modification to a file content material.
Protecting monitor of file adjustments inside the group helps system directors and safety analysts have organization-wide visibility of those adjustments and sort out safety incidents promptly. As soon as configured, FIM occasions will be considered on the Wazuh dashboard.

Monitoring file integrity and entry
The Wazuh FIM functionality runs a baseline scan and shops the cryptographic checksum and different attributes of monitored recordsdata. When a change is made to a monitored file, the FIM compares its checksum and attributes to the baseline. If any discrepancy is recognized, an alert shall be triggered. Wazuh file integrity monitoring functionality tracks particulars similar to the method or consumer that changed a essential file and when the adjustments had been made. Utilizing the Wazuh FIM functionality, organizations can guarantee compliance with varied sections of regulatory requirements similar to:
- PCI DSS requirement 11.5.2
- CM-3 of NIST 800-53
- Article 5.1. (f) of GDPR
- Workforce Safety §164.308(a)(2) of HIPAA.
For instance, we will configure the Wazuh FIM to observe the SSH configuration file /and so on/ssh/sshd_config file on a Linux endpoint. Malicious actors usually goal the SSH configuration file to weaken safety by altering port numbers or disabling sturdy ciphers. The Wazuh FIM can detect unauthorized modifications by monitoring adjustments to this file. The next configuration on a Wazuh agent units the Wazuh FIM functionality to observe the /and so on/ssh/sshd_config file on a monitored endpoint:
<syscheck>
<directories>/and so on/ssh/sshd_config</directories>
</syscheck>
The picture under reveals alerts triggered when alterations are made to the SSH configuration file.

Equally, the /and so on/ufw listing sometimes accommodates configuration recordsdata for UFW (Uncomplicated Firewall), a preferred firewall utility in Linux. These recordsdata outline the principles figuring out which community visitors is allowed or blocked in your system. An attacker may modify the UFW guidelines to open ports sometimes closed by default, permitting unauthorized entry to a system or inner community companies.
We will configure the Wazuh FIM to observe the /and so on/ufw listing. That is configured by including the configuration under within the agent configuration file on the monitored endpoint. We additionally allow the attribute whodata, which information the consumer that adjustments a monitored file.
<syscheck>
<directories whodata="yes">/and so on/ufw</directories>
</syscheck>
The picture under reveals alerts triggered when alterations are made to the UFW rule recordsdata.
