Setting Up a Basic IT System

5. IT Security

Computer viruses, hackers and other threats can cause major disruption to your business.

You should take steps to prevent this.

5.1 Install security software on all your business computers.

• Security software protects you from viruses and hackers.
• All-in-one security suites offer the essential protection you need.
• Alternatively, you can purchase separate packages to protect against viruses, spyware, hackers, and so on.

5.2 Use firewalls.

• A firewall filters network trafffic and can block hackers from trying to access your systems.
• Each of your computers should have its own software firewall.
• For extra protection, you can install a hardware firewall between your network and the Internet.
• A hardware firewall is essential if you have a network server.
• 5.3 Keep all your software up-to-date.
• Software companies release regular security updates to their products.
• Install these on your systems promptly.

5.3 Create a robust backup system.

• Set up a procedure for making regular partial and complete backups.
• Store backups off-site. Keep them away from heat, moisture and magnetism.
