Penetration testing follows a step-by-step process from planning to cleanup to find and report security weaknesses.

Execution Sample

Cybersecurity

1. Plan test scope and goals
2. Gather info about target
3. Scan for open ports and services
4. Exploit vulnerabilities to enter
5. Keep access to explore deeper
6. Document findings and fix
7. Remove all test traces

This sequence shows the main steps a penetration tester follows to simulate an attack and report security issues.

Analysis Table

Step	Action	Purpose	Tools/Techniques	Outcome
1	Planning & Reconnaissance	Define scope and gather target info	Interviews, OSINT, network maps	Clear test goals and target data
2	Scanning & Enumeration	Find open ports and services	Nmap, Nessus, Netcat	List of active services and potential entry points
3	Gaining Access	Exploit vulnerabilities to enter	Metasploit, manual exploits	Access to target system gained
4	Maintaining Access	Keep control for further testing	Backdoors, rootkits	Persistent access established
5	Analysis & Reporting	Document findings and risks	Report templates, screenshots	Detailed report for fixing issues
6	Cleanup	Remove all test traces	Manual removal, scripts	No evidence of testing left
7	End	Testing complete	N/A	Test finished successfully

💡 All steps completed to simulate attack and report security weaknesses.

Key Insights - 3 Insights

Why do testers spend time on reconnaissance before attacking?

Reconnaissance gathers important target info to plan effective attacks, as shown in execution_table step 1 where clear goals and data are collected.

What happens if cleanup is skipped after testing?

Skipping cleanup leaves traces that can alert defenders or cause issues, but execution_table step 6 shows cleanup removes all test evidence.

Why maintain access after gaining entry?

Maintaining access allows deeper testing and checking persistence, as seen in step 4 where persistent access is established for further exploration.

Visual Quiz - 3 Questions

Look at the execution_table, at which step is access first gained to the target system?

A Step 2 - Scanning & Enumeration

B Step 3 - Gaining Access

C Step 4 - Maintaining Access

D Step 1 - Planning & Reconnaissance

💡 Hint

Check the 'Outcome' column for when 'Access to target system gained' appears.

According to variable_tracker, what is the 'Access Level' after Step 5?

A Persistent Access

B User Access

C None

D Admin Access

💡 Hint

Look at the 'Access Level' row under 'After Step 5' column.

If the 'Cleanup' step is skipped, what would likely happen to the 'Test Footprint' variable?

A It would remain 'Clean'

B It would become 'Minimal'

C It would stay 'Medium' or higher

D It would reset to 'None'

💡 Hint

Refer to 'Test Footprint' changes in variable_tracker after Step 6.

Concept Snapshot

Penetration testing follows these steps:
1. Plan and gather info
2. Scan for open services
3. Exploit to gain access
4. Maintain access for deeper testing
5. Analyze and report findings
6. Clean up all test traces
Each step builds on the last to safely simulate attacks and improve security.

Full Transcript

Penetration testing methodology is a step-by-step process used to find security weaknesses by simulating attacks. It starts with planning and gathering information about the target. Then testers scan for open ports and services to find possible entry points. Next, they exploit vulnerabilities to gain access to the system. After gaining access, they maintain it to explore further and test persistence. Once testing is done, they analyze and report all findings clearly. Finally, they clean up to remove any traces of testing. This process helps organizations understand and fix their security gaps.
