Ethical Hacking: System Hacking

Learn to detect, prevent, and counter system hacking, including password cracking, privilege escalation, spyware, and keylogging, and study for the Certified Ethical Hacker exam.

System hacking is the way hackers get access to individual computers on a network. Ethical hackers learn system hacking to detect, prevent, and counter these types of attacks. This course explains the main methods of system hacking—password cracking, privilege escalation, spyware installation, and keylogging—and the countermeasures IT security professionals can take to fight these attacks. Security expert Lisa Bock also covers steganography, spyware on a cell phone, and tactics for hiding files and tools.
