According to a report by Computer Weekly, the Information Commissioner's Office (ICO) has dealt with more data breach reports and issued more fines in the past year than ever before.

10 Tips to Improve Data Security

Half of all information security breaches are due to human error, more often than not, by people not understanding the policy.

With tough penalties of up to €50m under the GDPR, there has never been a bigger incentive to get data security right.

We have 10 simple tips that will help to improve your data security.

1. Familiarise yourself with your company's IT rules

That includes all procedures and policies relating to information security, privacy and confidentiality. You can't fully protect yourself and your firm if you don't know what to do.

2.Be clear about your responsibilities

Know what data you are responsible for, what you are allowed to do with it and what you aren't.

3. Take extra care when taking data offsite

Only do this if it is absolutely essential; make sure that any data is encrypted or password-protected; and ensure that it's returned or deleted after use.

4. Only access or transfer data via secure networks

Accessing your company's network via unsecured networks, including public WiFi hotspots outside of your office will make you more vulnerable.

5. Only share information on a 'need to know' basis

Avoid forwarding data to groups of people and take care typing email addresses to avoid sending data to the wrong recipient.

6. Understand and check document classifications

Even people in the same department or function may have different access rights so check who is entitled to what and how documents are classified before sharing them. Use clear classifications such as Private, Confidential, Public and use these to grant privileges.

7. Follow the password rules

Use strong passwords and change them regularly; avoid sharing your password with anyone else as your password may give others access to restricted information.

8. Only process work information via work devices

That means any information relating to your job, including emails, documents and instant messages. Avoid forwarding data to your personal email or smartphone or using personal devices and connections for printing etc.

9. If you're unsure how to protect your firm's data, ask

You can get more advice and support from the IT department or your manager.

10. Never conceal data losses or breaches

If you make a mistake, tell your manager or IT department immediately so your firm can act quickly to limit their losses.
