Top tips for Cyber Security in your office

In the modern world no-matter how expensive the security system protecting your network is, it is hard to predict the potential damage caused by a simple mistake by a trusted internal user. Each time you click an unfamiliar link, or open an attachment from an unrecognised sender on your workstation, this mistake could directly cost your business money, either through fines relating to data protection, or downtime for hours or days while the problem is resolved.

To help you avoid these incidents, we’ve compiled a list of things you should consider when using your email and the Internet in general. If you are running a business, firewalls and antivirus software are the basic tools to increase security, but these alone do not guarantee protection from criminals using social engineering to dupe users into opening up security holes.


1. Good password management

Use a strong mix of characters, and try not to use the same password for multiple sites or services. Never share your password with others, and never write it down.

2. Be careful what you plug in to your device

Malware can be spread through infected flash drives, external hard drives, and even smartphones.

3. Be wary of email links/attachments

If a link or attachment arrives unexpectedly, treat it with a healthy dose of caution. Modern criminals are very good at crafting emails that appear genuine and difficult to spot. Double check if the sender email address matches the expected one. When you hover your mouse over the URL/link, does the popup match the text displayed in the mail? Even unusually poor spelling or grammar can alert you to something phishy.

4. Trusted Device / Trusted Network

Sensitive browsing, such as banking or shopping should only be done on a device that belongs to you, on a network you trust. Whether it’s a friends phone, a public computer, or a café’s free WiFi – your data could be copied or stolen.

5. Back up data regularly

Back up your data regularly, and make sure your anti-virus software is always up to date. This task can be a pain for a lot of people especially if you have never been attacked, but it is probably the only thing that will 100% cover you if an attack results in massive data loss.

6. Never Leave Your Device Unattended

This rule applies to all devices; your computer, phone, or tablet, or even hard drives kept in drawers. Tip: Pressing Windows and the ‘L’ key on your PC will lock it quickly.

7. Watch what you share on social networks

Criminals can use the information you share freely on the social media to build a very detailed profile of who you are, and this information can then be used to impersonate you, gain access to your other accounts, or even determine what sort of email links you are likely to quickly click on.

8. Act quickly when compromised

Be sure to monitor your accounts and network for suspicious activity. Anything out of the ordinary could be a sign you have been compromised, and the quicker you act, the better your chances of recovering with minimal damage.
