Introduction to Pentesting
Penetration testing, or pentesting, is a simulated cyber attack against your computer system to check for exploitable vulnerabilities. It’s a crucial component of any comprehensive security plan. The process involves assessing your system’s defenses using the same techniques and ethical hacking tools as the hackers. However, the goal is to strengthen these defenses, not exploit them.
In the context of the CompTIA Pentest+ certification exam, understanding the tools and techniques used in pentesting is essential. This certification validates your knowledge and ability to perform tasks on the cyber security frontline. This will make you an invaluable asset to any organization.
Phases of Pentesting
Pentesting is typically conducted in phases, each with its own set of tools and techniques.
Scanning
The first phase of pentesting involves scanning the target system for open ports, services, and system details. Tools like Nmap, Nessus, and OpenVAS are commonly used in this phase.
Credential Testing
This phase involves attempting to crack usernames and passwords to gain access to systems. Tools like John the Ripper, Hashcat, and Medusa are often used for credential testing.
Wireless
In the wireless phase, the security of wireless networks is tested. Tools like aircrack-ng and Kismet are used to monitor, attack, and crack wireless networks.
Web Application
Web application testing involves looking for vulnerabilities in web applications. Tools like Burp Suite, OWASP ZAP, and sqlmap are commonly used in this phase.
Social Engineering
Social engineering is the art of manipulating people to give up confidential information. The Social Engineering Toolkit (SET) is a popular tool for simulating these types of attacks.
Remote Access
This phase involves gaining and maintaining access to the system. Tools like Metasploit and Secure Shell (SSH) are often used in this phase.
Networking
In the networking phase, the focus is on protecting and testing the security of the network. Tools like Nmap and Scapy are used to analyze network traffic and test network security.
Miscellaneous
This phase includes various other aspects of pentesting, such as digital forensics, which involves investigating and recovering data from digital devices. Kali Linux is a popular tool in this phase due to its wide range of pentesting tools.
