Security Incident Response

Initial Source of Information

If you have any information about potential security events or incidents relating to the IP Fabric, please notify us in one of the following ways:

In line with industry best practice, we also monitor standard data sources including (but not limited to):

  • Mitre CVE database for software vulnerabilities
  • debian-security mailing list
  • internal monitoring (doesn’t cover customers’ deployments)


We use industry standard CVSS scoring for classification of the reported / discovered vulnerabilities.

CVSS Score

Timeline and escalation path is as follows

CVSS Score Qualitative Rating SLA Rating Reaction Time Escalation
0.0 None
0.1 – 3.9 Low
4.0 – 6.9 Medium Normal Next two working days VPE, SRE
7.0 – 8.9 High High Next working day CTO, VPE, SRE
9.0 – 10.0 Critical Critical 4h during business hours CTO, VPE, SRE

Note that we don’t show Remediation Time in this table, instead showing Reaction Time as a metric. It is hard to predict upfront time complexity of a particular issue, or availability of the solution (particularly in a third-party component on which there may be a dependency). Reaction time refers to the time to reach a proposal for solution of the issue with time estimate.


Every security incident has a tracking ticket, which contains:

  • CVSS score
  • CVE number / link (when applicable)
  • Affected customers (if specific)
  • security tag assigned

Also, the IP Fabric internal security Slack channel will be notified, with a dedicated channel created for a specific incident as necessary.

We select one person to be responsible for coordinating internal communication and to serve as an interface to the teams communicating directly with customers. Typical candidates: DevOps TL, Head of Development, VPE, CTO.
