Keep up-to-date

As soon as a new security system is released people start looking for ways to break it. It’s axiomatic that new releases of software and operating systems will have bugs. These bugs can lead to security lapses.

As problems are found and the vendors notified, they will issue fixes, patches and/or work-arounds so as to prevent further problems. The responsibilities of vendors to disseminate information about security problems is not clear. It’s no good running to a lawyer AFTER your system is compromised. Better to be active in preventing problems and actively seek out information about problems that could cause damage to your systems.

Register Software

Yes. Fill in those boring licence forms and send them off.

Monitor Alert Services

Regularly read the information on the various alert services. Don’t just monitor those that are peculiar to your installation. Many times, problems in one O/S will be mirrored in others.

Subscribe to Vendor Alert Services

Most NOS vendors now have email servers that broadcast security information to those who have registered. Make sure that you’re connected to all sources of information that may affect your system.

Regularly review/audit network security

A regular review of the network from a security viewpoint is always useful. Be prepared to change the system in view of what the review finds. have external auditors look at the system regularly. This provides an independent review. Use the auditors as tools to test what you’ve done. Then adjust anything that they find. In some cases you may decide to live with something the auditors didn’t like. But YOU DECIDE.

Monitor Software loaded onto the network

Ever since the first virus appeared you’ve been warned about running or loading software from external sources without first scanning it. Now you need to review that software’s operations in the light of how it might impact security as well.
