A comprehensive open source security platform
Wazuh provides a security solution capable of monitoring your infrastructure, detecting threats, intrusion attempts, system anomalies, poorly configured applications and unauthorized user actions. It also provides a framework for incident response and regulatory compliance.
Wazuh agent
The Wazuh lightweight agent is designed to perform a number of tasks with the objective of detecting threats and, when necessary, trigger automatic responses. The agent core capabilities are:
- Log and events data collection
- File and registry keys integrity monitoring
- Inventory of running processes and installed applications
- Monitoring of open ports and network configuration
- Detection of rootkits or malware artifacts
- Configuration assessment and policy monitoring
- Execution of active responses
The Wazuh agents run on many different platforms, including Windows, Linux, Mac OS X, AIX, Solaris and HP-UX. They can be configured and managed from the Wazuh server.
Wazuh server
The Wazuh server is in charge of analyzing the data received from the agents, processing events through decoders and rules, and using threat intelligence to look for well-known IOCs (Indicators Of Compromise). A single Wazuh server can analyze data from hundreds or thousands of agents, and scale horizontally when set up in cluster mode.
The server is also used to manage the agents, configuring and upgrading them remotely when necessary. Additionally the server is capable of sending orders to the agents, for example to trigger a response when a threat is detected.
Elastic Stack
Alerts generated by Wazuh are sent to Elastic Stack, where they are indexed and stored. The unique integration between Wazuh and Kibana (one of the components of the Elastic Stack), provides a powerful user interface for data visualization and analysis, that can also be used to manage and monitor the configuration and status of the agents.
Wazuh web user interface includes out-of-the-box dashboards for regulatory compliance (e.g. PCI DSS, GDPR, CIS), detected vulnerable applications, file integrity monitoring, configuration assessment, security events, cloud infrastructure monitoring and others.
Security Analytics
Wazuh is used to collect, aggregate, index and analyze security data, helping organizations detect intrusions, threats and behavioral anomalies.
As cyber threats are becoming more sophisticated, real-time monitoring and security analysis are needed for fast threat detection and remediation. That is why our light-weight agent provides the necessary monitoring and response capabilities, while our server component provides the security intelligence and performs data analysis.
Intrusion Detection
Wazuh agents scan the monitored systems looking for malware, rootkits and suspicious anomalies. They can detect hidden files, cloaked processes or unregistered network listeners, as well as inconsistencies in system call responses.
In addition to agent capabilities, the server component uses a signature-based approach to intrusion detection, using its regular expression engine to analyze collected log data and look for indicators of compromise.
Log Data Analysis
Wazuh agents read operating system and application logs, and securely forward them to a central manager for rule-based analysis and storage.
The Wazuh rules help make you aware of application or system errors, misconfigurations, attempted and/or successful malicious activities, policy violations and a variety of other security and operational issues.
File Integrity Monitoring
Wazuh monitors the file system, identifying changes in content, permissions, ownership, and attributes of files that you need to keep an eye on. In addition, it natively identifies users and applications used to create or modify files.
File integrity monitoring capabilities can be used in combination with threat intelligence to identify threats or compromised hosts. In addition, several regulatory compliance standards, such as PCI DSS, require it.
Vulnerability Detection
Wazuh agents pull software inventory data and send this information to the server, where it is correlated with continuously updated CVE (Common Vulnerabilities and Exposure) databases, in order to identify well-known vulnerable software.
Automated vulnerability assessment helps you find the weak spots in your critical assets and take corrective action before attackers exploit them to sabotage your business or steal confidential data.
Configuration Assessment
Wazuh monitors system and application configuration settings to ensure they are compliant with your security policies, standards and/or hardening guides. Agents perform periodic scans to detect applications that are known to be vulnerable, unpatched, or insecurely configured.
Additionally, configuration checks can be customized, tailoring them to properly align with your organization. Alerts include recommendations for better configuration, references and mapping with regulatory compliance.
Incident Response
Wazuh provides out-of-the-box active responses to perform various countermeasures to address active threats, such as blocking access to a system from the threat source when certain criteria are met.
In addition, Wazuh can be used to remotely run commands or system queries, identifying indicators of compromise (IOCs) and helping perform other live forensics or incident response tasks.
Regulatory Compliance
Wazuh provides some of the necessary security controls to become compliant with industry standards and regulations. These features, combined with its scalability and multi-platform support help organizations meet technical compliance requirements.
Wazuh is widely used by payment processing companies and financial institutions to meet PCI DSS (Payment Card Industry Data Security Standard) requirements. Its web user interface provides reports and dashboards that can help with this and other regulations (e.g. GPG13 or GDPR).
Cloud Security
Wazuh helps monitoring cloud infrastructure at an API level, using integration modules that are able to pull security data from well known cloud providers, such as Amazon AWS, Azure or Google Cloud. In addition, Wazuh provides rules to assess the configuration of your cloud environment, easily spotting weaknesses.
In addition, Wazuh light-weight and multi-platform agents are commonly used to monitor cloud environments at the instance level.
Containers Security
Wazuh provides security visibility into your Docker hosts and containers, monitoring their behavior and detecting threats, vulnerabilities and anomalies. The Wazuh agent has native integration with the Docker engine allowing users to monitor images, volumes, network settings, and running containers.
Wazuh continuously collects and analyzes detailed runtime information. For example, alerting for containers running in privileged mode, vulnerable applications, a shell running in a container, changes to persistent volumes or images, and other possible threats.
