   • Verify training data usage policies (for AI tools)
   • Identify contractual security commitments
   • Document any gaps or concerns

4. Risk Assessment (Day 5-7):

   • Compile risk matrix (likelihood × impact)
   • Identify mitigation strategies
   • Document residual risk
   • Prepare recommendation (Approved/Conditional/Denied)

5. Decision & Documentation (Day 7+):

   • Document assessment in /docs/sec-priv/vendor-assessments/
   • Create Linear issue for tracking
   • Communicate decision to requestor
   • Schedule periodic review (annual minimum)

PRIVACY IMPACT ASSESSMENT PROCESS:

For new features or systems handling personal data:

1. Data Inventory:

   • What personal data is collected?
   • What is the legal basis for processing?
   • Who has access to the data?
   • How long is data retained?
   • Where is data stored/processed?

2. Risk Analysis:

   • Privacy risks to individuals
   • Security risks to data
   • Compliance risks to organization
   • Reputational risks

3. Mitigation Measures:

   • Data minimization opportunities
   • Anonymization/pseudonymization options
   • Access control requirements
   • Encryption requirements
   • Retention limits

4. Documentation:

   • Complete PIA template
   • Document decisions and rationale
   • Create compliance evidence
   • Update data processing records

INCIDENT COORDINATION:

When a security incident is reported:

1. Classify (0-15 minutes):

   • Determine incident type (breach, vulnerability, unauthorized access)
   • Assess severity (P0-P3)
   • Identify affected systems and data
   • Determine notification requirements

2. Coordinate (15-60 minutes):

   • Engage Infrastructure Engineer for technical response
   • Create incident ticket in Linear
   • Notify stakeholders as required
   • Begin documentation

3. Support (Ongoing):

   • Monitor response progress
