Vulnerability SLA Policy Template

1. Purpose

This policy establishes remediation timelines for security vulnerabilities based on severity classification, defines escalation procedures for SLA breaches, and specifies reporting requirements for compliance tracking.

2. Scope

This policy applies to all information systems, applications, and infrastructure components managed by [Organization Name].

3. SLA Definitions

Severity CVSS Range Remediation Timeline Grace Period Escalation Path
Critical 9.0 - 10.0 48 hours 12 hours Asset Owner -> Security Director -> CISO
High 7.0 - 8.9 15 calendar days 5 days Asset Owner -> Team Lead -> Security Director
Medium 4.0 - 6.9 60 calendar days 14 days Asset Owner -> Team Lead
Low 0.1 - 3.9 90 calendar days 30 days Asset Owner

4. Exception Process

4.1 Exception Request Requirements

  • CVE identifier and affected system details
  • Business justification for extension
  • Compensating controls implemented
  • Proposed new remediation date
  • Risk acceptance signature from system owner and CISO

4.2 Maximum Exception Duration

  • Critical: 14 days maximum extension
  • High: 30 days maximum extension
  • Medium: 60 days maximum extension
  • Low: 90 days maximum extension

5. Alerting Configuration

5.1 Notification Schedule

80% SLA elapsed -> Warning to asset owner (email + Slack)
100% SLA elapsed -> Breach alert (email + Slack + PagerDuty for Critical/High)
SLA + 24 hours -> Escalation Level 1 (team lead)
SLA + 72 hours -> Escalation Level 2 (director)
SLA + 7 days -> Escalation Level 3 (CISO)

5.2 Notification Channels

  • Email: All severity levels
  • Slack: High and Critical severity
  • PagerDuty: Critical severity SLA breaches only
  • Jira: Automatic ticket creation for all findings

6. Reporting Requirements

6.1 Weekly Report

  • Count of open findings by severity
  • Count of SLA breaches by severity
  • Top 5 assets with most open findings
  • Remediation velocity trend

6.2 Monthly Report

  • Overall SLA compliance rate by severity
  • Mean time to remediate by severity
  • Exception count and approval rate
  • Quarter-over-quarter improvement trends

6.3 Executive Dashboard

  • Overall compliance percentage
  • Risk exposure trend (critical/high open count over time)
  • Team/business unit comparison
  • Regulatory compliance status (PCI, SOC2, HIPAA)

7. Compliance Mapping

Regulation Requirement SLA Alignment
PCI DSS 4.0 Req 6.3.3 Critical/High within 30 days
SOC 2 CC7.1 Evidence of SLA tracking and remediation
HIPAA 164.312(a)(1) Risk-based remediation timeline
CISA BOD 22-01 KEV remediation 14 days for KEV-listed CVEs
NIST CSF 2.0 ID.RA-01 Risk-ranked vulnerability management

8. Roles and Responsibilities

  • Asset Owner: Remediate within SLA, request exceptions when needed
  • Security Team: Monitor SLA compliance, manage alerting system
  • Team Lead: Review team SLA metrics, escalate blockers
  • CISO: Approve critical exceptions, review monthly metrics
