Wazuh integrates seamlessly with third-get together risk intelligence alternatives like VirusTotal, MISP, URLHaus, and YARA. These integrations empower the examining of file hashes, IP addresses, and URLs in opposition to acknowledged destructive indicators of compromise (IOCs). Wazuh integration with these answers improves your business’ overall security posture by giving additional insights on likely threats, malicious things to do, and IOCs.
A Vulnerability is a security weak spot or flaw that can be exploited by threats to perform destructive activities in a laptop or computer process. Wazuh provides the Vulnerability Detector module to assist businesses detect and prioritize vulnerabilities in their environments. This module employs facts from multiple feeds such as Canonical, Microsoft, the Countrywide Vulnerability Databases (NVD), and much more to offer true-time information and facts about vulnerabilities.
Threat detection and response
Wazuh uses its modules, decoders, ruleset, and integration with third-get together alternatives to detect and shield your electronic assets from threats. These threats incorporate malware, web, network assaults, and a lot more.
The Wazuh File Integrity Checking module monitors directories and studies file addition, deletion, and modifications. It is utilized to audit delicate files but can be put together with other integrations to detect malware. The rootcheck module is applied to detect rootkit behaviors like concealed documents, ports, and strange processes. The Wazuh lively response module provides automatic reaction steps these as quarantining contaminated techniques, blocking network website traffic, or terminating the ransomware procedures. The mixture of these modules enables for a rapid response to mitigate the effects of cyberattacks.

Audit and regulatory compliance
Security auditing and compliance are two crucial principles for any enterprise that aims to shield itself from cyber attacks. Security auditing is the systematic approach of analyzing an organization’s information systems, practices, and procedures to recognize vulnerabilities, evaluate dangers, and make sure that security controls purpose as meant. Regulatory compliance refers to the procedure of certifying that an business adheres to a set of set up criteria, restrictions, or laws connected to information security.
