Course 27 - Hacking Web Applications, Penetration Testing, CTF | Episode 5: Penetration Testing Terminology and Core Security Concepts

In this lesson, you’ll learn about:Core penetration testing terminology, including the difference between a vulnerability (a weakness in a system) and an exploit (the method used to leverage that weakness).Payload concepts, understanding how attackers deliver custom code to a target system after successful exploitation.Shellcode fundamentals, the low-level assembly instructions often embedded within exploits to execute specific actions on a compromised machine.Shell types and communication methods, including:Reverse shells, where the target initiates a connection back to the tester’s listener.Bind shells, where the target opens a listening port and the tester connects directly.Web shells, typically deployed through vulnerable web applications.Interpreter shells, providing command execution through scripting environments.Zero-day vulnerabilities, defined as previously unknown security flaws that are exploited before developers can release a patch or mitigation.The CIA triad, the foundational security model emphasizing:Confidentiality – preventing unauthorized data disclosureIntegrity – ensuring data remains accurate and unalteredAvailability – maintaining reliable system and data accessYou can listen and download our episodes for free on more than 10 different platforms:https://linktr.ee/cybercode_academy
