Computers are used by people every day, for varied purposes. The purposes can be as different as banking and communicating via e-mail to shopping and investing. They have become a very important part of our lives. However, apart from using a computer system for Internet purposes, measures should also be taken to ensure its network security.
Instructions to Set Up a Home Computer Security System
There are some essential and important steps which can be followed to protect the Home Computer Security System against computer virus, hackers, spyware and other unwanted material.
Routers: They provide the base for computer security. They must be bought and set up even if you have only one computer, because the router creates a LAN of your private computer addresses and connects it to the Internet. This way you can hide your computer from the Internet. The router performs a ‘Network Address Translation’ which creates a Firewall. This Firewall is very effective as it protects against unwanted, unsolicited and potentially dangerous software from the Internet that can get into your LAN.
Firewall: Software firewalls need to be purchased in addition to the hardware firewall solution which a router provides. It is necessary because the network connection has entrances or ‘ports’ that allow internet traffic in, through the web browser and e-mail. This firewall configures these ports so that they can be hid from the rest of the Internet, thereby avoiding the hackers who continuously search for vulnerable computers on the web. Users who have Windows XP or above are already equipped with software Firewall solutions. They can just turn it on by accessing the Control Panel through the ‘start’ button. Zone Alarm and COMODO are famous firewall software, which can otherwise be bought or downloaded.
Anti-Virus Software: If you surf the web and download content regularly, getting Anti-virus software is a must. Once any virus reaches a system, it spreads across the hardware and can cause severe damage to files and disk drives. Some of the popular Anti-Virus software brands are Avast, Norton AntiVirus and McAfee VirusScan.
Anti-Malware Software: Malware is a program which damages the computer system even without the user being aware of it. It is not only a computer virus but includes worms, spyware, Trojan horses, crimeware and other unwanted, malicious content. One needs to check if his AntiVirus software can handle these software. Otherwise he may have to buy or download another program to take care of it. Symantec, Norton and BitDefender are software offering the protection.
There are few other things that must be borne in mind:
The Default SSID network name must be changed. Its broadcast should be disabled. MAC address filtering should be enabled to prevent the network from outside, unwanted access. Passwords must be used for all accounts.
There are various security risks and countermeasures that are associated with computer networks. Not only should users do their best to avoid malicious damage to the system and prevent it against unwanted access, but efforts are also needed to spread awareness in this regard.
