Network security issues

The increase in businesses connecting their systems and using the Internet has its drawbacks. When all computers are networked, one user's problems may affect everyone. You should consider the greater potential for data loss, security breaches and viruses when creating a network.

It is important to ensure data security through regular housekeeping such as backing up files, password routines and system logs. It is important to remove access from employees who leave, otherwise they may still be able to access customer records.As your data will be stored in one location on the server, physical security is very important. See our guide on keeping your systems and data secure.

You should enhance your system security to protect your business from potential virus attacks and hacking. This should include anti-virus software and a firewall or software barrier. See our guide on IT security: the basics.Keep this up to date and download relevant patches - updates to software that fix security threats - because new viruses are frequently released. If you are affected by a virus your employees could lose data and have difficulties using their computers, and your business could come to a standstill.


Irrespective of the technology solution you select, you should seek expert advice when your system is installed - from your Internet service provider, system provider, installer or an adviser. As when seeking any type of professional guidance, you should find out whether any adviser is familiar with businesses of your size or in your sector, or follow personal recommendations.
