What is Penetration Testing?
Introduction
(Protecting Your Systems from Hackers)
Imagine the internet as a vast network of connected devices, each a potential target for cyberattacks. These attacks can cause widespread damage, steal data, disrupt operations, or even hold systems hostage. To prepare for these threats, security teams conduct a simulated attack called penetration testing, or pen testing for short. This involves testing their systems for weaknesses that hackers could exploit. It's like a security drill, helping organisations identify and fix problems before they become real disasters.
What is Penetration Testing?
Penetration testing, also known as pen testing, is a security exercise where a cybersecurity expert tries to find and exploit weaknesses in a computer system or network. This is done to identify and fix security flaws before malicious actors can exploit them. Think of it like a practice drill for your security defenses.
Example - 'A retail chain hires a pen tester to test the security of its point-of-sale (POS) systems. The pen tester discovers that the POS systems are vulnerable to a malware attack that could steal credit card information from customers. The retail chain implements security measures to protect its POS systems and customer data.'
Benefits of penetration testing:
Identify and fix security weaknesses.
Reduce the risk of cyberattacks.
Improve compliance with industry regulations
Types of penetration testing:
Black-box testing: The pen tester has no prior knowledge of the system they are testing.
White-box testing: The pen tester has access to all of the information about the system they are testing.
Gray-box testing: The pen tester has some information about the system they are testing, but not all.

Penetration Testing Process
Planning: The pen tester gathers information about the system, defines the scope of the test, and identifies assets that are off-limits.
Reconnaissance: The pen tester gathers more information about the system, such as IP addresses, open ports, and running services.
Vulnerability scanning: The pen tester uses automated tools to scan the system for vulnerabilities, identifying known weaknesses in software, hardware, and the network.
Exploitation: The pen tester attempts to exploit the vulnerabilities they have identified.
Post-exploitation: The pen tester gathers evidence of their exploits and assesses the impact of the vulnerabilities. They provide a report outlining their findings and recommendations for remediation.

Penetration Testing vs. Vulnerability Scanning
Penetration testing and vulnerability scanning are both important tools for improving cybersecurity, but they serve different purposes.
Vulnerability scanning is an automated process that identifies known vulnerabilities in a system. It is a good way to get a quick overview of the security posture of a system, but it does not provide a comprehensive assessment of the system's security.
Penetration testing is a manual process that involves trying to exploit vulnerabilities in a system. It is a more thorough way to assess the security of a system, but it is also more time-consuming and expensive.
The key differences between penetration testing and vulnerability scanning:
Vulnerability scanning should be used regularly to get a quick overview of the security posture of a system. It is also a good way to identify vulnerabilities that can be easily exploited.
Penetration testing should be used periodically to get a more comprehensive assessment of the security of a system. It is also a good way to identify vulnerabilities that are not easily found by automated scanners.

Guide To Do Penetration Testing
Phase 1: Planning and Reconnaissance
Define scope: Determine the systems to be tested and the types of tests to be conducted (black-box, white-box, or gray-box).
Gather information: Use publicly available sources (e.g., social media, job postings) and internal sources (e.g., network diagrams, documentation) to gather information about the target system.
Identify attack vectors: Analyze the gathered information to identify potential attack vectors, such as open ports, vulnerable software, and social engineering opportunities.
Phase 2: Scanning and Vulnerability Assessment
Network scanning: Use network scanners to identify open ports, running services, and other network vulnerabilities.
Vulnerability scanning: Use vulnerability scanners to identify known vulnerabilities in the target system's software, hardware, and firmware.
Manual vulnerability assessment: Perform manual testing to validate the findings of the automated scans and identify any additional vulnerabilities that may not be detected by automated tools.
Phase 3: Exploitation
Select vulnerabilities to exploit: Prioritize the vulnerabilities based on their severity and exploitability.
Develop exploits: Develop or utilize existing exploits to exploit the selected vulnerabilities.
Document exploits: Document the exploits and the steps taken to execute them.
Phase 4: Post-exploitation
Gather evidence: Gather evidence of the exploits, such as screenshots and logs.
Assess impact: Assess the impact of the exploits on the target system.
Recommend remediation: Recommend remediation measures to address the exploited vulnerabilities.
Phase 5: Reporting and Remediation
Prepare a report: Prepare a comprehensive report documenting the findings of the penetration test, including the identified vulnerabilities, exploits, and remediation recommendations.
Present findings: Present the findings to the organization's stakeholders, such as the IT team and management.
Remediate vulnerabilities: Collaborate with the IT team to remediate the identified vulnerabilities.
