Answers
Answer:
Employees can unwittingly sabotage systems
and create computer security threats through
sheer ignorance.
Explanation:
How to prevent insider security threats:
Virus: A computer virus is malignant code that can steal passwords, spam contacts, corrupt files, log keystrokes and even take over the infected device. To become infected, someone must purposely or accidentally spread the infection. The city of Akron, Ohio, suffered a virus attack in January 2019 that was traced back to ransomware set off after two employees opened fake invoices sent through spam emails.
Antivirus: Antivirus software is designed to detect, remove and prevent malware infections on a device or network. Though specifically created to eliminate viruses, antivirus software can also aid against spyware, adware and other malicious software. Basic antivirus programs scan files for the presence of malicious software, allow users to schedule automatic scans and remove any malicious software.
Spyware: Any software installed on a device without the end user's permission is classified as spyware, even if it is downloaded for a harmless purpose. Adware, Trojans and keystroke loggers are all examples of spyware. Without antispyware tools, spyware can be difficult to detect. To prevent spyware, network administrators should require remote workers to access resources over a network through a virtual private network that includes a security scan component.
Malware: Malicious software, also known as malware, can steal, encrypt or delete private information, monitor computer activity without user permission or alter core computing function of the device. Spyware and viruses are examples of malware. In 2017, health insurance company Anthem paid $115 million in a class-action lawsuit after a record-breaking number of customers' data was left vulnerable because of a security breach. Links to malware in a targeted spear phishing email campaign began in 2014 and went undetected for months. After one employee clicked the links, malware provided hackers with remote access to computers in the network and access to personally identifiable information -- all the tools needed for identity theft.
