Incident Response

How to effectively detect, respond to and resolve cyber incidents

It is essential that you prepare for an incident and practice the response. This may be as simple as rebuilding a few devices and restoring the latest backup right through to a major systems investigation.

Cyber incident response is not just an IT issue,  it is a combined response of :-

  • people with the correct knowledge and skills
  • the correct incident response processes
  • appropriate and timely communication
  • back up equipment and data

The level of complexity and the nature of any incident will determine how simple or complex the response needs to be. Running through the most likely scenarios are helpful in testing a planned response a building resilience.

A cybersecurity playbook can be developed to provide all members of an organisation with a clear understanding of their roles and responsibilities regarding cybersecurity – before, during and after a security incident. These can be developed for common incident scenarios that might be encountered.

The NCSC has a step by step guide to developing your cyber incident plan with the following steps and more.

  • Triage
  • Categorise the incident and escalate if required.
  • Analyse
  • Contain/mitigate
  • Remediate/eradicate
  • Recover

Take time to look at these and get prepared.
