Describe how operating systems use the following security tools: firewalls, automatic updating, antivirus software, and spyware and malware detection software.

Question

What will be an ideal response?

Answer 1

Operating systems can include the following security tools:?•Firewall: Security experts recommend using a firewall and configuring it to turn on or off automatically.•Automatic updating: Security updates are issued at least once daily, and other updates are generated on an as-needed basis. Many people enjoy the convenience offered by allowing these fixes to install automatically instead of continually checking for new files to download. Users can view the update history to see when specific updates were installed. If an update caused a problem to occur, a user can uninstall these new files.•Antivirus software: Many operating systems include antivirus programs that are updated regularly. Some users mistakenly think they should install and run another antivirus program simultaneously for more protection. They should not run more than one antivirus program on a computer, because multiple programs might conflict with one another and slow overall performance.•Spyware and malware detection software: Sophisticated malware and spyware threats are emerging at an unparalleled rate, so comprehensive spyware and malware detection software is mandatory to fend off attacks on the computer or device. The operating system generally is scheduled to scan and update when the computer is idle, such as in the middle of the night. Overall, the security tools should run constantly and quietly in the background to ensure a safe computing experience.
