Day-to-Day Responsibilities
Monitor and triage security alerts from SIEM, EDR and other tools to separate real incidents from false alarms.
Investigate confirmed incidents to find how the attacker got in, which systems and accounts they touched, and whether data left the network.
Contain threats quickly by isolating infected machines, blocking malicious IP addresses or disabling compromised accounts.
Collect and preserve digital evidence, such as logs, disk and memory images, in a way that holds up to audit or legal review.
Coordinate with IT, legal, compliance and business teams, and sometimes with regulators or law enforcement, during a breach.
Write clear incident reports and timelines for management, and recommend fixes that prevent a repeat.
Run post-incident reviews and practice drills (tabletop exercises) so that playbooks and the team improve over time.
