Setting Up Your First IT System

6. Securing Your Data

The information you hold on your IT system is valuable, and holding business information on a computer creates a security risk.

6.1 Physically protect computer equipment.

• Stealing a PC or server is the most direct way of getting hold of information and the easiest way to discover how to gain access later.

6.2 Design your network with security in mind.

• Use passwords to restrict access. Focus on high-risk information and systems. For example, confidential information and financial systems.
• As far as possible, isolate or protect computers with direct Internet access. Consider installing firewall software to control data coming into and out of your system, and anti-virus software that filters destructive data.

6.3 Create a robust back-up system.

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

6.4 Ensure employees understand the importance of security.

• Make security a part of employees' contracts.
• Only give Internet access and email accounts to those who really need them.

6.5 Make sure technical support is available. This can range from a suitably-qualified individual looking after all IT issues through to engaging specialist support contractors.

• Work out the longest time you could work without your system before your business is damaged and make sure that your support could get things up and running before then.
