IR Team

An IR Team, or Incident Response Team, is a specialized group within an organization responsible for detecting, responding to, and recovering from cybersecurity incidents like data breaches or cyberattacks. Their main goal is to minimize damage and restore normal operations as quickly as possible.

TECHNICAL DEFINITION

An IR Team (Incident Response Team) is a dedicated cybersecurity entity tasked with executing an organization's incident response plan to address security incidents, including detection, analysis, containment, eradication, recovery, and post-incident review, thereby protecting critical assets and ensuring business continuity. This specialized team comprises professionals with expertise in digital forensics, network security, and threat intelligence, crucial for managing cybersecurity events.

BACKGROUND

In information security, threat hunting is the process of proactively searching for threats against computer systems in order to protect them. This is in contrast to traditional threat management measures, such as firewalls, intrusion detection systems (IDS), malware sandbox and SIEM systems, which typically involve an investigation of evidence-based data after there has been a warning of a potential threat. Threat analyst Lesley Carhart stated that there is no consensus amongst practitioners what threat hunting actually entails.
