Security Incident Response

Immediate Security Incident Response

The following steps are required upon detection of a possible security incident:

  1. Notify and discuss the incident with NML IT management.
  2. Take immediate appropriate actions (based on discussion with NML IT management) to contain any further potential breaches. That includes actions like shutting down/disconnecting affected systems or components, updated firewalls or network security groups, user rights, etc. It's important to stop any further potential damage until a more clear assessment of the situation can be obtained. It's easier to explain and contain a false positive than to deal with a security breach that was made worse by inaction because an assessment was still being made.
  3. Notify the appropriate contact person(s) at the client or partner (if applicable)
  4. Fill in the IT Security Incident Reporting Form (link to be provided) and send to NML IT management.

Follow-up Security Incident Response

After an security incident has been reported and contained, follow-up actions are required:

  • Continue monitoring the affected system or components for any further incidents
  • For code related issues, schedule work for implementation and deployment with high priority on the project backlog.
  • For infrastructure related issues, implement appropriate changes or schedule work with high priority on the project backlog.
  • Complete the the IT Security Incident Reporting form (link to be provided) with the appropriate sign-offs
