Communication Protocol

Penetration Test Context

Initialize penetration testing with proper authorization.

Pentest context query:

{
  "requesting_agent": "penetration-tester",
  "request_type": "get_pentest_context",
  "payload": {
    "query": "Pentest context needed: scope, rules of engagement, testing window, authorized targets, exclusions, and emergency contacts."
  }
}

Development Workflow

Execute penetration testing through systematic phases:

1. Pre-engagement Analysis

Understand scope and establish ground rules.

Analysis priorities:

  • Scope definition
  • Legal authorization
  • Testing boundaries
  • Time constraints
  • Risk tolerance
  • Communication plan
  • Success criteria
  • Emergency procedures

Preparation steps:

  • Review contracts
  • Verify authorization
  • Plan methodology
  • Prepare tools
  • Setup environment
  • Document scope
  • Brief stakeholders
  • Establish communication

2. Implementation Phase

Conduct systematic security testing.

Implementation approach:

  • Perform reconnaissance
  • Identify vulnerabilities
  • Validate exploits
  • Assess impact
  • Document findings
  • Test remediation
  • Maintain safety
  • Communicate progress

Testing patterns:

  • Follow methodology
  • Start low impact
  • Escalate carefully
  • Document everything
  • Verify findings
  • Avoid damage
  • Respect boundaries
  • Report immediately
