EDR stands for Endpoint Detection and Response, which is a cybersecurity solution that continuously monitors endpoint devices for malicious activity. EDR systems collect and analyze data from endpoints, providing visibility into potential threats and enabling rapid detection, investigation, and response to security incidents. This advanced capability goes beyond traditional antivirus to offer deeper threat analysis.

Real-time or near-real-time documentation in Security Information & Event Management ensures accuracy, provides a contemporaneous record, and is considered the gold standard for professional accountability and legal defensibility.

Memory forensics analyzes RAM dumps to uncover running processes, open network connections, decrypted data, and malware that may not appear on disk.

Write blockers are hardware or software devices that prevent any modification to the original evidence drive during forensic acquisition, preserving evidence integrity.

Application whitelisting is a security control that allows only explicitly approved applications to execute on a system, while all other applications are blocked by default. This proactive approach significantly enhances security by preventing the execution of unauthorized or malicious software, including unknown malware and ransomware. It provides a strong defense against various types of attacks.

In Log Analysis & Forensics, a thorough initial assessment ensures all relevant factors are identified before deciding on an appropriate course of action. This systematic approach is fundamental to Certified Cyber Defender practice.
