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 the ones in the full backup. incremental backup creates copies of all the files, or parts of files that have changed since previous backups of any type (full, differential or incremental).
2. if you did a full backup on Sunday. An incremental backup made on Monday, would only contain files changed since Sunday, and an incremental backup on Tuesday, would only contain files changed since Monday, and so on. 3.
A cold backup site is little more than an appropriately configured space in a building. Everything required to restore service to your users must be procured and delivered to the site before the process of recovery can begin. As you can imagine, the delay going from a cold backup site to full operation can be substantial. A warm backup site is already stocked with hardware representing a reasonable facsimile of that found in your data center.
To restore service, the last backups from your off-site storage facility must be delivered, and bare metal restoration completed, before the real work of recovery can begin. hot backup sites have a virtual mirror image of your current data center, with all systems configured and waiting only for the last backups of your user data from your off-site storage facility. As you can imagine, a hot backup site can often be brought up to full production in no more than a few hours. A hot backup site is the most expensive approach to disaster recovery. Task 4:
The Business plan on the multidimensional external forces that brought changes to Nokia
Nokia’s website explains the goal and mission of Nokia as ‘To be technology leader in a world where everybody and everything is connected’ The website also states Nokia reinvented which explains for the fact that the company is gearing up to face the changes in the market.
