Custom Endpoint Detection and Response System

Custom Solution

EDR for Greater Security and Accountability Across All Devices

With the expansion of remote workers and the increased value of data accessibile via many disparate workstations the need for greater compromise detection and protection on all devices is stronger than ever. SEIRIM used open source and best value solutions to create a custom and comprehensive system for our clients.

PROJECT AIMS

Objectives

Real-Time Threat Detection and Prevention

Implement a robust EDR solution to continuously monitor the client’s endpoints for any signs of malicious activity. By leveraging real-time threat detection capabilities, quickly identify potential risks such as malware infections and prevent them from escalating into significant security breaches.

Comprehensive Visibility into Endpoint Activities

Provide the client with visibility into their endpoint operations. Enable the client to track activities across all devices, identify unauthorized access, unusual behaviors, and any suspicious processes, helping to ensure a stronger security posture.

Threat Hunting and Behavioral Analysis

Facilitate proactive threat hunting activities using the EDR system’s behavioral analysis features. By analyzing patterns in endpoint behavior, enable identifying hidden threats that traditional detection methods might miss, offering the client an added layer of protection against sophisticated attacks.

Centralized Management and Reporting

Build for the client a centralized management that consolidates security data from all endpoints into a single dashboard, or at least a very few of them. This shall streamline incident management, allowing IT and security to efficiently monitor, analyze, and report on endpoint health and vulnerabilities in real time.

Continuous Endpoint Monitoring and Updates

Ensure that the client’s endpoints remain continuously monitored with regular updates to both threat intelligence and system patches. Foster ongoing vigilance to help maintain up-to-date defenses against evolving threats, ensuring that no endpoints are left vulnerable to emerging security risks.

Strategies Implemented for the Endpoint Detection and Response Solutions

SEIRIM's deliverables focused on deploying, configuring, and optimizing the open source solutions Wazuh’s capabilities to ensure continuous monitoring, real-time threat detection, and robust security management for the client’s infrastructure and devices.

Wazuh Agent Deployment on Workstations and Servers

We deployed the Wazuh agents on all client workstations and Linux servers, ensuring seamless integration across the client’s entire environment. This agent collects real-time data about system activity, file integrity, and any potential security events. The deployment process was carefully managed to avoid disruptions, providing continuous monitoring for all devices.

Centralized Log Collection and Management Setup

To enhance visibility, we set up centralized log collection using Wazuh's log management capabilities. By aggregating logs from all workstations and Linux servers into a central location, we enabled the client’s IT team to efficiently monitor and analyze activity from a single interface, streamlining their incident detection and response process.

Security Rules Configuration and Customization

We customized Wazuh’s security rules tailored to the client’s specific environment. This included configuring predefined rules and creating custom ones based on the organization’s unique needs. The rules provided real-time detection of potential security threats, such as unauthorized access, malicious behavior, and configuration changes on both workstations and servers.

File Integrity Monitoring (FIM) Setup

To protect critical system files and configurations, we configured Wazuh’s File Integrity Monitoring (FIM) feature across all workstations and Linux servers. This allowed us to track changes to system files, providing the client with alerts if any unauthorized or suspicious modifications were made, helping them detect potential attacks like malware or insider threats early.

Alerting and Notification System Implementation

SEIRIM implemented a sophisticated alerting system in Wazuh, configured to notify the client’s security team of potential incidents in real time. Alerts were fine-tuned to prioritize critical events, ensuring that the security team could quickly assess and respond to the most urgent threats, reducing the time between detection and action.

Integration with Existing SIEM Solution (e.g., ELK Stack)

As part of the Wazuh implementation, we integrated the solution with the client’s existing SIEM system, the ELK Stack (Elasticsearch, Logstash, and Kibana). This integration enabled enhanced analytics and reporting capabilities, providing a comprehensive view of the organization’s security posture across all workstations and Linux servers. It also helped correlate Wazuh events with other security data sources, improving overall threat intelligence.
