Protect your Network (Network Security)

● 

Find out if your device which connects the organisation to the Internet – most com-

monly a router supplied by the Internet Service Provider (ISP) – has a firewall built in. 

If not then instal a proprietary firewall (for example, from mainstream suppliers like 

Symantec, Sophos, Kaspersky, etc., which is often included in a suite of software) on 

your PC or laptop. Follow the instructions to keep it properly configured and updated.

● 

Take note of any warning messages and follow the guidance offered.

● 

Consult an expert if you think your network has been compromised – you might 

know this has happened if you notice unusual activity, such as unusually high activity 

or no activity.
