Malware is often one of the first ways hackers will target a system or network. Ethical hackers can combat malware such as viruses and worms by understanding exactly how they are created, dispersed, detected, and neutralized. This course is part of our Ethical Hacking series, designed to give security professionals the tools to defend against attacks and prepare for the Certified Ethical Hacking exam. Join security ambassador Lisa Bock for an overview of malware, the differences between viruses and worms, and current virus trends and types, including macro, boot, shell, and cluster viruses. She also reviews the threat of polymorphism, techniques for overriding parasitic viruses, and the growing threat of ransomware. By the end of the course, you'll have the skills to detect and defend against malware on your own computer or your company's network.
