Making protection work
WHEN connected to the Internet, regardless of whether you are using dial-up or broadband, the following tips should be considered.

p Back-up your essential data frequently to a safe location. Make sure the data being backed up has been virus and integrity checked first.

p Purchase a good quality firewall. The cheaper option is a software firewall such as ZoneAlarm (www.zonelabs.com). Hardware firewalls, such as those embedded in some routers, are expensive, but add another layer of good security.

p Purchase file integrity checking software. These keep track of the state of your files and can detect if and when they have been altered. The Languard File Integrity Checker (www.gfi.com) is popular.

p Purchase vulnerability identification software. These scan your network systems and identify security vulnerabilities. The GFiLanguard Network Security Scanner (www.gfi.com) is popular.

p Check for operating system and application software updates regularly. These fix a range of software problems including security vulnerabilities.

p Purchase anti-virus software and update it regularly. It should always be active and running in the background.

p Subscribe to a security alert notification service. The CERT Coordination Center (www.cert.org) is excellent.

p Do not open e-mail attachments unless they are expected. Delete them and then empty the ‘deleted items’ folder.

p Get to know what is normal behaviour for your computer network. This will increase the probability of hacking activity being noticed.

p Post a clear and unambiguous policy regarding the use of the Internet within your organisation. Prohibit activities than incur unnecessary cost or put the company at risk in any way.

Although not a guarantee that your systems will be completely safe, these measures will help reduce the likelihood of external attack and internal misuse.
