Endpoint Protection, Detection & Response

Malware remains a predominant threat to IT security, developing rapidly and encompassing various forms such as viruses, worms, rootkits, botnets, file-less malware, ransomware, and crypto-miners. The cybersecurity industry has shifted from prevention to detection and response, but some forms of malware like ransomware and wipers remain obvious post-infection, leaving users with options like paying the ransom (not advised), wiping machines, and restoring from backups. Prevention is crucial, but no solution is foolproof; hence, robust backup/restore processes are vital. Ransomware often infiltrates via phishing campaigns, malicious links, Office document macros, drive-by downloads, and malvertising.

Sophisticated viruses are now polymorphic, evading detection by altering their structure. Worms exploit unpatched systems and open ports, while rootkits provide attackers control over infected machines. Botnets leverage compromised devices for extensive attacks such as DDoS. File-less malware propagates through process or memory injection to evade signature-based scanners. Crypto-jacking uses users’ resources for unauthorized cryptocurrency mining, increasing costs and depleting device batteries.

Endpoint Protection (EPP) and Detection & Response (EDR) are essential, with EPDR tools combining these functionalities. They log activities centrally, allow remote endpoint examination, and update detection rules. They support querying and evaluation of cyber threat intelligence, event correlation, memory analysis, and activity playback. EDR solutions enable customizable automation for investigations and remediation, performing tasks like process termination and endpoint rollback.

XDR (Extended Detection & Response) advances EPDR by integrating endpoint, network, and cloud aspects, providing comprehensive security. EPDR solutions must interoperate with tools like SIEM and SOAR, often supporting CEF, REST APIs, and syslog for integration. The adoption of MITRE ATT&CK framework is widespread among security vendors to map malicious actors' tactics, techniques, and procedures.

The report highlights evolving market trends, noting shifts to vendor cloud-hosted management, variations in secondary protection functions, and innovations using AI. The Overall Leaders in EPDR are CrowdStrike, Cybereason, ESET, Microsoft, SentinelOne, Sophos, and Symantec, recognized for product, innovation, and market leadership. Challenges and opportunities for differentiation among vendors are discussed.
