Role of a Threat Hunter:
A threat hunter proactively searches for cyber threats that have evaded traditional security defenses. This role is crucial in identifying sophisticated and stealthy adversaries that bypass automated detection systems.
Key Responsibilities:
Proactive Threat Identification:
Threat hunters use advanced tools and techniques to identify hidden threats within the network. This includes analyzing anomalies, investigating unusual behaviors, and utilizing threat intelligence.
