Learn Hacking From Scratch

Discover how to prepare for security incidents using incident response policies, defined roles, and a NIST-based phase model to guide containment and debriefing.

Explore the evolution of hacking and cyber crime from early hackers to modern ransomware and denial-of-service attacks, and learn ethical hacking mindsets to anticipate threats.

Explore ethical hacking through the footprinting, scanning, and enumeration stages, gathering passive and active information to profile a target and inform later penetration testing.

Explore network scanning to identify live hosts and weaknesses, learn sniffing concepts including active and passive modes, and examine session hijacking to take over an established connection.

Explore how denial of service attacks overwhelm networks, causing outages and revenue loss, and examine evasion, social engineering, and the role of cryptography in information security.

Explore how social engineering exploits human trust and authority to obtain information or access through non-technical manipulation. Recognize telltale signs and the need for training and security policies.

Explore footprinting, scanning, and enumeration within system hacking, and learn to gather target information, identify network hosts, and understand password cracking as a step toward accessing systems.

Learn how sql injection exploits unvalidated input to manipulate databases and alter website data. See how input validation and whitelisting prevent these attacks and protect data integrity.
