Improving your Penetration Testing Skills

By: Gilberto Najera-Gutierrez, Juned Ahmed Ansari, Daniel Teixeira, Abhinav Singh

Overview of this book

Penetration testing (or ethical hacking) is a legal and foolproof way to identify vulnerabilities in your system. With thorough penetration testing, you can secure your system against the majority of threats. This Learning Path starts with an in-depth explanation of what hacking and penetration testing are. You’ll gain a deep understanding of classical SQL and command injection flaws, and discover ways to exploit these flaws to secure your system. You'll also learn how to create and customize payloads to evade antivirus software and bypass an organization's defenses. Whether it’s exploiting server vulnerabilities and attacking client systems, or compromising mobile phones and installing backdoors, this Learning Path will guide you through all this and more to strengthen your defense against online attacks. By the end of this Learning Path, you'll have the knowledge and skills you need to invade a system and identify all its vulnerabilities. This Learning Path includes content from the following Packt books: • Web Penetration Testing with Kali Linux - Third Edition by Juned Ahmed Ansari and Gilberto Najera-Gutierrez • Metasploit Penetration Testing Cookbook - Third Edition by Abhinav Singh , Monika Agarwal, et al.

Secure communication over SSL/TLS

Secure Sockets Layer (SSL) is an encryption protocol designed to secure communications over the network. Netscape developed the SSL protocol in 1994. In 1999, the Internet Engineering Task Force (IETF) released the Transport Layer Security (TLS) protocol, superseding SSL protocol version 3. SSL is now considered insecure because of multiple vulnerabilities identified over the years. The POODLE and BEAST vulnerabilities, which we will discuss further in later sections, expose flaws in the SSL protocol itself and hence cannot be fixed with a software patch. SSL was declared deprecated by the IETF, and upgrading to TLS was suggested as the protocol to use for secure communications. The most recent version of TLS is version 1.2. We always recommend that you use the latest version of TLS and avoid allowing connections from clients using older versions...
