Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Root Cause Remediation (Immediate — Within 30 Days)
  2. Control Gap Closure (Short-Term — Within 90 Days)
  3. Policy Updates (Medium-Term — Within 90 Days)
  4. Training Modifications (Medium-Term — Within 90 Days)

What it can do on your machine

Read from SKILL.md and the folder at commit 9b2ef9e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Breach Remediation loads about 2.3k tokens when it runs, and up to ~3.4k if it reads all its reference files. Until then it costs about 117 tokens; SKILL.md has 1,040 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~117
When it runs · the whole SKILL.md, loaded when a task matches
~2.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Conducting Post-Breach Remediation

Overview

Post-breach remediation transforms the findings from a breach investigation into concrete corrective actions that prevent recurrence and demonstrate accountability under GDPR Art. 5(2) and Art. 24. Effective remediation goes beyond fixing the immediate vulnerability — it addresses root causes, closes systemic control gaps, updates policies and training, enhances monitoring, and satisfies regulatory follow-up requirements.

Lessons Learned Framework

Step 1: Root Cause Remediation (Immediate — Within 30 Days)

Address the direct technical and procedural cause of the breach:

Root Cause CategoryRemediation ApproachExample (SPG-BREACH-2026-003)
Stale privileged accountDecommission account, implement lifecycle managementRevoked svc-migration-2024; deployed automated service account expiry (90-day review cycle)
Phishing vulnerabilityDeploy phishing-resistant MFA, enhance email filteringMigrated from push-based MFA to FIDO2/WebAuthn for all privileged accounts
Insufficient network segmentationImplement micro-segmentationDeployed database-tier isolation; access only via approved bastion host with session recording
Inadequate access review scopeExpand access review to include all account typesAdded service accounts, API keys, and machine accounts to quarterly access certification
Step 2: Control Gap Closure (Short-Term — Within 90 Days)

Identify and close broader security and privacy control gaps revealed by the breach:

  1. Detection gap: Was the breach detected by the organization's own controls, or was it reported externally? If detection was delayed, strengthen monitoring.
  2. Response gap: Were response procedures followed? Where did the team deviate from the plan? Update procedures based on actual experience.
  3. Communication gap: Were internal and external communications timely and accurate? Update communication templates and escalation matrices.
  4. Documentation gap: Were the Art. 33(5) documentation requirements met in real-time? Improve documentation tools and checklists.
  5. Vendor/processor gap: If a processor was involved, was the Art. 28 DPA adequate? Were processor security requirements sufficient? Update vendor risk assessment and DPA terms.
Step 3: Policy Updates (Medium-Term — Within 90 Days)

Review and update affected policies based on breach findings:

PolicyUpdate RequiredOwnerDeadline
Access Control PolicyInclude service accounts in scope; define lifecycle management requirementsCISO15 April 2026
Incident Response PlanUpdate awareness definition; add holding statement template; revise escalation matrixDPO + CISO30 April 2026
Ransom Payment PolicyDocument Board-approved position on ransom paymentsGeneral Counsel31 May 2026
Vendor Risk ManagementAdd security assessment questionnaire updates based on processor breach lessonsProcurement + DPO30 June 2026
Data Retention PolicyVerify that expired data was actually deleted per schedule (breach may have revealed retention failures)DPO30 June 2026
Step 4: Training Modifications (Medium-Term — Within 90 Days)

Update training programs to address the human factors contributing to the breach:

Training ModuleTarget AudienceUpdateDelivery Method
Phishing awarenessAll employeesAdd scenario based on the actual phishing email that initiated SPG-BREACH-2026-003 (with identifying details removed)Interactive simulation via KnowBe4
MFA securityAll employees with MFAAdd push-fatigue attack awareness; train on rejecting unexpected MFA promptsMandatory e-learning module
Incident reportingAll employeesClarify that unusual system behavior must be reported immediately, even if uncertainUpdated in annual privacy awareness training
Breach responseIncident response teamTabletop exercise based on this breach scenarioSemi-annual tabletop exercise
Privileged access managementIT operations, DBAsService account lifecycle management proceduresDepartment-specific workshop
Step 5: Monitoring Enhancements (Medium-Term — Within 90 Days)

Strengthen detection and monitoring based on gaps the breach revealed:

EnhancementDescriptionOwnerDeadline
Service account anomaly detectionSIEM rule to alert when service accounts authenticate outside scheduled batch windows or from non-whitelisted IPsSOC Lead15 April 2026
MFA push-fatigue detectionAlert when an account receives more than 3 MFA push notifications in 5 minutes without successful authenticationSOC Lead30 April 2026

Step 6: Regulatory Follow-Up (Ongoing)

Manage ongoing obligations to supervisory authorities:

  1. Supplementary notifications: Provide any outstanding information committed to in the initial Art. 33 notification (e.g., exfiltration determination, final data subject count).
  2. Authority inquiries: Respond promptly and comprehensively to any follow-up questions from the supervisory authority.
  3. Remediation evidence: Be prepared to provide evidence of remediation actions to the authority upon request. Maintain a remediation tracker with completion dates and evidence references.
  4. Regulatory proceedings: If the authority initiates formal proceedings, coordinate response with external counsel.
  5. Annual DPO report: Include the breach and remediation status in the DPO's annual report to the Board and supervisory authority.

Post-Breach Review Meeting

Agenda (Conducted 30 Days After Breach Closure)
  1. Breach summary: 5-minute recap of the incident.
  2. Root cause review: Confirm root cause analysis is accurate and complete.
  3. Remediation status: Review all remediation actions — completed, in progress, overdue.
  4. Effectiveness assessment: Have the implemented remediations been tested and proven effective?
  5. Residual risk: What risk remains after remediation? Is it within the organization's risk appetite?
  6. Lessons for next time: What would we do differently? What worked well?
  7. Documentation closure: Confirm all Art. 33(5) documentation is complete.

Demonstrating Accountability

Under GDPR Art. 5(2), the controller must demonstrate compliance. Post-breach remediation evidence serves this purpose:

  • Before the breach: Risk assessments, security measures, training records, and policies demonstrate preventive efforts.
  • During the breach: Incident response documentation, notification records, and communication logs demonstrate responsive handling.
  • After the breach: Remediation tracker, updated policies, enhanced controls, and improved training demonstrate learning and improvement.

A supervisory authority reviewing the organization's breach response will assess not only whether the breach was handled correctly but whether the organization took meaningful steps to prevent recurrence.
