Whether you are Microsoft, the Federal Government, VISA, a small business
or an Individual, without proper planning, you can be a victim of a security
compromise. While you always hear about the high profile cases, there are daily network security failures taking place in today’s networked environments that never get reported. According to the 2004 Computer Crime and Security Survey conducted by The Computer Security Institute and FBI, companies sustained losses of $141,496,560 in 2004 from computer security incidents.
There was a time when only large companies worried about network security breaches. However, in this new world where everyone from the home user to the large corporation relies on technology for functions that range from email to the storage of sensitive data, it seems no one is immune to the havoc that viruses, worms, spyware and hackers can wreak.
So, what are you to do? How do you keep your computer secure?
There is no fool-proof method to ensure total security without unplugging your connection to the Internet.
Given the frequency with which new viruses are introduced, it seems impossible to keep up 100% with the constantly changing threats. Symantec’s semi-annual Internet Security Threat Report for the first half of 2004, found over 10,000 malicious programs that could infect a Windows PC. There will always be new threats. The important thing is to have a plan in place for dealing with them. .
Back to the basics: What every Computer should have for a more secure experience.
- Passwords that change on a regular basis and are not intuitive.
- The National Cyber Security Alliance recommends using hard-to-guess passwords that are at least eight characters long and mix upper case, lower case and numbers. Don't share your password with anyone and change it at least every 90 days.
- Up-to-date anti-virus software on all workstations and servers.
- Since new viruses are created every day, it is essential to have anti-virus software that can be updated regularly to protect against the latest threats, preferably automatically updated to every workstation from your server.
- Firewall with strong traffic policies to prohibit and allow communication.
- Firewalls provide protection between your computer and the world. They filter and block potentially dangerous and unauthorized data from the Internet and also let "good" data reach your computer. There are two types of firewalls: software and hardware. Software firewalls run on individual computers while hardware firewalls protect several computers at once. The size and needs of your company determines whether you choose one or both.
- Email anti-virus and SPAM filters.
- Using filters to intercept email viruses and SPAM is an important way to protect your network. There are two types of email viruses: those that are enabled when opening an email attachment (i.e. the LoveLetter virus in 2000) and those that run automatically regardless of an attachment (such as the Nimda virus). An email anti-virus filter will catch incoming messages that contain viruses and stop them in their tracks. Typically you will receive an email notification to let you know that a virus was detected and quarantined.
- SPAM is one of the biggest wastes of bandwidth and time in your company. A SPAM filter separates unsolicited emails from those that are legitimate, placing the unsolicited messages in a separate folder or deleting it. There is always the risk that the filter may block messages that are legitimate, so it is essential to develop the right mix of protection. Most SPAM filters permit you to specify which emails you want to receive in your inbox based on a list of email addresses that you specify, often called a "white list".
- Anti-Spyware Technology
- Spyware, by definition, is "any technology that aids in gathering information about a person or organization without their knowledge". On the Internet, spyware is programming that is put in someone's computer to secretly gather information about the user and relay it to advertisers or other interested parties. Spyware can get in a computer as a software virus or as the result of installing a new program. It gives advertisers information about your web surfing habits so they can target you for particular products. Anti-spyware is software or technology that disables spyware so you can regain your privacy.
