What is Ethical Hacking?

🎯 Definition and Purpose

Ethical Hacking is the practice of intentionally probing systems, networks, and applications to find security vulnerabilities using the same techniques as malicious hackers, but with proper authorization and for legitimate security purposes.

🔍 Key Characteristics

Authorized access - Written permission required
Legal compliance - Follows laws and regulations
Professional conduct - Ethical standards maintained
Documentation - Detailed reporting of findings
Confidentiality - Information protection assured
Remediation focus - Helps improve security posture

📊 Industry Statistics

Expected growth: 15.1% CAGR (2021-2028)
Data breaches prevented: 67% through ethical hacking
Average cost saving: $3.86 million per avoided breach
Security vulnerabilities found: 85% through pen testing
Time to patch: Reduced by 60% with ethical hacking

How would you handle discovered vulnerabilities during active testing?

Risk Management:

How would you ensure testing doesn't disrupt critical banking services?
What backup and rollback plans would you implement?
How would you handle emergency situations during testing?
What communication protocols would you establish?

Phase 3: Reporting and Remediation (11 minutes)

Reporting Strategy:

How would you structure reports for different audiences (executives, IT, compliance)?
What vulnerability classification and risk rating system would you use?
How would you prioritize remediation recommendations?
What evidence and documentation standards would you maintain?

Post-Assessment Activities:

How would you support the client's remediation efforts?
What follow-up testing or validation would you recommend?
How would you handle responsible disclosure if applicable?
What ongoing security improvement recommendations would you provide?

Deliverables:

Pre-engagement checklist and documentation requirements
