Clirsec provides necessary contextual insight into activities involving the network, computer systems and cloud services such as microsoft 365. This context is necessary for security teams to help understand the difference between its activities and malicious behavior. without the context that Clirsec provides, it is hard for any security team to identify malicious behaviors until it is too late. Additionally, without proper event records and visibility, it is nearly impossible to track down would-be attackers.
CLIRSec EPIC Agent:
CLIRSec EPIC Agent is an essential cyber security solution for organizations of all sizes. It runs across a wide range of platforms, including Linux, Windows, macOS, Solaris, AIX and others, ensuring total coverage regardless of the systems in use. The agent helps to prevent cyber threats by providing threat prevention as well as detection and response capabilities. Additionally, it collects data from your system and application which then gets securely forwarded to the CLIRSec SIEM server where it is monitored for cyber security incidents. By leveraging their MDR (Managed Detection & Response) services you are able to maximize the cyber security posture for both large and small businesses alike.
CLIRSec EPIC Agent modules
CLIRSec EPIC’s advanced cyber security agent modules provide comprehensive protection from cyber threats. Every module is configurable, allowing organizations to tailor the cyber security protection suite to their specific needs. This approach ensures that any cyber security reporting and incident response requirements are met by having the option to enable or disable features like cyber threat prevention, cyber intrusion monitoring, Managed Detection and Response (MDR) services and Security Information and Event Management (SIEM). The domain-specific Module Architecture of CLIRSec EPIC allows for organizations to customize their cyber security stack as technology and security threats evolve.
Log collector: Log collectors, such as the agent component described, are a key part of cyber security threat prevention and Managed Detection and Response (MDR) services. By collecting operating system and application log messages, monitoring them in a Security Information and Event Management (SIEM) system in real time, cyber security professionals have any early warning they need to detect cyber threats before they strike. These log collectors support XPath filters for Windows events and recognize multi-line formats like Linux Audit logs. With the ability to enrich JSON events with additional metadata cyber security teams are even better equipped to spot cyber security risks before they become catastrophes.
Command execution: Agents run authorized commands periodically, collecting their output and reporting it back to the CLIRSec SIEM server for further analysis. You can use this module for different purposes, such as monitoring hard disk space left or getting a list of the last logged-in users.
File integrity monitoring (FIM): This module monitors the file system, reporting when files are created, deleted, or modified. It keeps track of changes in file attributes, permissions, ownership, and content. When an event occurs, it captures who, what, and when details in real time.
Vulnerability Detection: CLIRSec 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.
Security configuration assessment (SCA): This component provides continuous configuration assessment, utilizing out-of-the-box checks based on the Center of Internet Security (CIS) benchmarks.
System inventory: This agent module periodically runs scans, collecting inventory data such as operating system version, network interfaces, running processes, installed applications, and a list of open ports.
Malware detection: Using a non-signature-based approach, this component is capable of detecting anomalies and the possible presence of rootkits. Also, it looks for hidden processes, hidden files, and hidden ports while monitoring system calls.
Active response: This module runs automatic actions when threats are detected, triggering responses to block a network connection, stop a running process, or delete a malicious file.
Container security monitoring: This agent module is integrated with the Docker Engine API to monitor changes in a containerized environment. For example, it detects changes to container images, network configuration, or data volumes. Besides, it alerts about containers running in privileged mode and about users executing commands in a running container.
Cloud security monitoring: This component monitors cloud providers such as Amazon AWS, Microsoft Azure, or Google GCP. It natively communicates with their APIs. It is capable of detecting changes to the cloud infrastructure (e.g., a new user is created, a security group is modified, a cloud instance is stopped, etc.) and collecting cloud services log data (e.g., AWS Cloudtrail, AWS Macie, AWS GuardDuty, Azure Active Directory, etc.)
Communication with CLIRSec SIEM server:
The CLIRSec EPIC agent communicates with the CLIRSec SIEM server to ship collected data and security-related events. Besides this, the agent sends operational data, reporting its configuration and status. Once connected, the agent can be upgraded, monitored, and configured remotely from the CLIRSec SIEM server.
The communication of the agent with the server takes place through a secure channel (TCP or UDP), providing data encryption and compression in real time. Additionally, it includes flow control mechanisms to avoid flooding, queueing events when necessary, and protecting the network bandwidth.
Wazuh is an open-source security platform designed to help organizations monitor and detect cyber threats across their IT infrastructure. The Wazuh agent, when installed on a Windows endpoint, provides several features and benefits related to cyber security detection and response. Here are some key features and benefits of using the Wazuh agent on a Windows endpoint:
- Host-based Intrusion Detection System (HIDS): The Wazuh agent acts as a host-based intrusion detection system, continuously monitoring the endpoint for suspicious activities, known attack patterns, and malicious behavior. It analyzes system logs, file integrity, registry changes, network traffic, and other indicators of compromise (IOCs) to identify potential security incidents.
- File Integrity Monitoring (FIM): The agent tracks changes made to critical system files and directories, ensuring the integrity of important operating system components. It alerts administrators if any unauthorized modifications occur, which could be an indication of a compromise or malware infection.
- Log Analysis and Correlation: Wazuh agent collects and analyzes logs from various sources on the Windows endpoint, including system logs, application logs, and security event logs. It performs log correlation to identify patterns or anomalies that may indicate an ongoing attack or security breach.
- Real-time Threat Detection: The agent uses predefined rules and signatures to detect common attack techniques, malware, and suspicious behavior in real-time. It can identify activities such as privilege escalation, lateral movement, brute-force attacks, and unauthorized access attempts, allowing organizations to respond promptly to potential threats.
- Active Response and Remediation: In addition to detection, the Wazuh agent supports active response capabilities, enabling administrators to take immediate action when a security incident occurs. This includes terminating malicious processes, isolating compromised systems from the network, or executing custom scripts for automated remediation.
- Centralized Management and Monitoring: The agent integrates with the Wazuh server, which provides a centralized management console for monitoring and managing multiple endpoints. Administrators can view real-time alerts, generate reports, and configure policies and rules for threat detection and response.
- Integration with SIEM and Threat Intelligence: Wazuh seamlessly integrates with Security Information and Event Management (SIEM) solutions, allowing the agent’s alerts and logs to be aggregated and correlated with data from other security tools. It can also leverage threat intelligence feeds to enhance detection capabilities and stay up-to-date with the latest known threats.
