New Computers
Not so long ago I chose to swap my coal powered computer for something a lot quicker and more with the times.

Information Security
Making sure that you have sufficient information security can be fairly simple. 
By installing spyware, anti virus programs and a firewall you can increase your information security. This should prevent your information from being stolen or corrupted as well as reducing spam in your email while preventing any sort of malicious software from attacking your computers.

Physical Security
On site security at an IT organisation can take on a number of forms. You can 
have security guards, CCTV and other means of physical security to protect your data as well as your property. Keypad coded access could be used to stop unauthorised persons stealing your rackmount server from your server room.
