Timely Analysis of Cyber Security Events to Identify Incidents
Quickly review cyber events to find and manage security threats.
Plain language
This control is about making sure that any suspicious activities or security alerts are looked at quickly. It's important because if a threat isn't caught in time, it could lead to data breaches, loss of money, or damage to your business's reputation.

Official control statement
Cyber security events are analysed in a timely manner to identify cyber security incidents.
Why it matters
Delayed analysis of cyber events can leave threats undetected, leading to data breaches or financial loss if incidents aren't swiftly identified.
Operational notes
Prioritise alerts by impact and confidence; use automated triage and defined escalation SLAs so events are reviewed quickly and incidents identified early.
Implementation tips
- Security officer: Ensure the security team has clear procedures for regularly checking security alerts and logs. This can be done by scheduling daily or weekly reviews of alerts generated by systems.
- IT manager: Set up automated alerts within your security software to notify the team of any unusual activity immediately. Use built-in alert settings provided by your security tools.
- IT support staff: Train the IT team on how to recognise suspicious events and what steps to take if something unusual is detected. Organise regular training sessions with real-world examples.
- Business owner: Ensure there's a designated person or team responsible for handling security alerts promptly. Communicate the importance of this role and include it in their job description.
Audit / evidence tips
- AskHow quickly are security alerts typically reviewed by your team?
- GoodThe team reviews and addresses security alerts within defined timeframes, usually within 24 hours, with logs showing prompt responses
- AskWhat procedures are in place to ensure timely analysis of cybersecurity events?
- GoodThere are documented procedures outlining steps for analysing and responding to security events within 24 hours
