Top 10 network security tips

Maintaining a secure IT network is easier than you think. With a little planning you can be prepared for any security breach, and ensure that your company is working in the most safe environment.

1. Get a security policy in place

A security policy is the best place to start, before you do anything else. Define the security levels that each user can access, and the responsibility levels of your administrators, managers and users.

2. Put someone in charge

It may sound obvious, but if you don’t have anyone who is responsible for looking after your security, you’re at risk. If you currently don’t have anyone responsible for your IT security, have a look at the services we offer.

3. Keep an inventory

Knowing where your equipment is and who has it is vital in ensuring your IT network is secured. Letting your hardware get into the hands of anyone and everyone is simply putting your company at risk.

4. Ensure all software is up-to-date and patched

If you’re software is out of date, then you’ve got a massive security flaw. As software gets patched and updated, it becomes more secure and less likely to suffer from a hack.

5. Establish a strong password policy

As we’ve discussed before, a password policy can often be the thing that saves your systems from being hacked. You can take as many precautions as you like, but if your users are still using “password123” as their passwords, then you’re going to have problems.

6. Don’t give more rights than necessary

You should only give your users the essential access they need and then they can request more access as and when they need it.

7. Restrict email attachments

Encourage cloud sharing and restrict attaching certain file extensions such as .exe .bat and .rar files to emails. Lots of viruses get spread this way.

8. Limit personal browsing

How much can you trust your workers? A security flaw is much more likely to come into play when users are accessing non-work related files. Let your users browse at home.

9. Don’t leave devices unattended

If users have access to portable devices such as laptops, tablets, and mobile devices, make it mandatory that they must lock their screens when not using the devices, or make it happen automatically. It’s good to encourage users to practice this habit while in the office too.

10. Back up data regularly

Be prepared for the worst. If you do have a security attack, then you will want to have a recent back up so that there won’t be too much disruption to your users.
