Cybersecurity for Manufacturing: Malware Overview 102
Cybersecurity for Manufacturing: Malware Overview covers different types of malware and how each functions. Manufacturing organizations using Industrial Internet of Things (IIoT) technology and other devices with internet functionality are vulnerable to a range of existing and emerging malware threats. In addition to traditional computer worms and viruses, criminal hackers create other types of malware, such as spyware, Trojans, and ransomware, to attack digital networks. They also employ phishing and other social engineering tactics to manipulate users into performing actions that plant malware onto systems.
Manufacturers should be aware of vulnerabilities associated with all their digital assets and have a basic understanding of the range of tools criminal hackers may use to compromise these assets. After taking this course, users will be able to recognize malware threats. Users will also understand the basic strategies of criminal hackers and ways to defend against them.
