An IT security plan is a key tool to help your business protect its IT systems. Your security plan should state how you will guard against security vulnerabilities to protect your business from disruption and financial loss.
A security plan allows you to understand what security vulnerabilities are present in your IT systems. You can then take steps to prevent these problems occurring.
Your IT security plan doesn’t have to be a long document covering all conceivable security vulnerabilities. But it should help you protect key business data and systems and ensure you adhere to relevant legislation, like the Data Protection Act.
Additionally, the more complex your business IT system is, the more security vulnerabilities you will face. A formal IT security plan is the most effective way to manage these. It makes you less likely to overlook any gaps in your defences.
There are several stages to writing an effective security plan:
It can be hard to spot all IT security vulnerabilities if you’re not an IT expert. Your IT supplier or an external consultant may be best placed to cast a critical eye over your systems and procedures.
Keep your IT security plan pragmatic. It should explain practical steps your business can take to guard against security vulnerabilities. If it can’t be put into action, your security plan is largely useless.
Once you’ve written your IT security plan, you should implement its recommendations in your business:
The information security risk to your business is constantly changing, so you should regularly review your security plan. Keep up-to-date with emerging security vulnerabilities by signing up to bulletins from security companies. Make sure you regularly update your protection. For example, by regularly updating your anti-virus software so that you are protected against the latest vulnerabilities.
If you make changes to your IT system or invest in new hardware or software, always review your security plan. Aim to identify any new security vulnerabilities.
Also review your policies and procedures 9–12 months after putting your plan into action to ensure you have implemented all the recommendations and that it is still fit for purpose. And put someone in charge of your security plan, so there’s no chance of it being neglected.
