Task 1: Hardware firewalls provide a strong degree of protection from most forms of attack coming from the outside to the internal network. Hardware firewalls can protect computers on a local area network and they can be implemented without much configuration difficulty.
Software firewalls are installed on individual computers and they need sufficient configuration to be effective. Software firewalls contain a set of related programs, usually located at a network gateway server, that protect the resources of a private network from users on other networks or from internal users. Software firewalls allow application screening to verify the interaction between the requesting client and the requested resource.
Task 2:
1. The companies that provide free trial versions of their software are Norton, McAfee, Panda, AVG, and Kaspersky. The companies who have free software versions are Panda, McAfee, and AVG.
2. Trojan horse was a program that was supposed to find and destroy computer viruses. A Trojan horse may be widely redistributed as part of a computer virus. Email attachments are a way for a sender to transmit files to another user via email. In a similar way to junk mail coming in your door at home, email users regularly receive unsolicited emails from unknown senders. These emails can often contain links to malicious web sites or have attachments containing malicious software. A drive-by download is when a malicious web site you visit downloads and installs software without your knowledge. The objective of drive-by downloads is usually to install malware to record what you type and what sites you visit, to search your computer for stored passwords, or to open your computer to remote control.
Task 3:
1. Full backup is a complete backup of everything you want to backup. Differential backup software looks at which files have changed since you last did a full backup. Then creates copies of all the files that are different from
