eBook What is Endpoint Detection and Response (EDR)?

A Practical Guide to Detecting Threats, Investigating Suspicious Activity, and Strengthening IBM i Security

Every organization needs continuous visibility into the activity occurring across its systems and applications. Traditional antivirus and preventive security controls can block known threats, but modern attacks increasingly involve suspicious behavior, compromised accounts, lateral movement, ransomware, and other techniques designed to evade traditional defenses. Endpoint Detection and Response (EDR) provides continuous monitoring, threat detection, investigation, and response capabilities to help organizations identify and contain suspicious activity before it becomes a serious security incident.

This practical eBook explains how Endpoint Detection and Response works, why EDR is an important component of a modern cybersecurity strategy, and how organizations can use it to improve threat detection, accelerate incident response, and protect business-critical IBM i environments.

Whether you’re an IT manager, cybersecurity professional, SOC analyst, compliance officer, system administrator, or IBM i specialist, this guide will help you understand the value of continuous endpoint monitoring, behavioral detection, threat investigation, and automated response.

Endpoint Detection and Response (EDR) provides continuous visibility into endpoint activity, helping security teams identify suspicious behavior, investigate potential threats, and take action before attackers can cause significant damage.

Why This eBook Matters

Modern cyberattacks are increasingly difficult to detect using preventive security controls alone. Attackers may use legitimate credentials, execute malicious processes, modify files, exploit trusted applications, or perform actions that initially appear to be normal system activity. Without continuous monitoring and behavioral analysis, suspicious activity can remain undetected until it results in data loss, operational disruption, ransomware, or a significant security incident.

Endpoint Detection and Response provides organizations with continuous visibility into endpoint activity, enabling security teams to identify suspicious behavior, investigate potential threats, understand attack patterns, and respond quickly. Instead of relying only on predefined signatures, EDR combines monitoring, behavioral analysis, threat detection, investigation, alerting, and response to provide a broader and more proactive approach to endpoint security.

For IBM i environments, EDR capabilities can provide an additional layer of protection alongside antivirus, anti-ransomware, auditing, access control, and other native security mechanisms. By monitoring relevant system and endpoint activity and correlating security events, organizations can improve their ability to detect attacks, investigate suspicious behavior, and respond before threats escalate.

When combined with IBM i auditing, File Integrity Monitoring, Anti-Ransomware, Antivirus, Multi-Factor Authentication, SIEM integration, and strong access controls, EDR becomes an important part of a layered cybersecurity strategy designed to protect critical IBM i systems and business data.
