In conclusion, there are a number of measures that you can implement to secure your network. However these need to be carefully planned and implemented with thought to requirements, future requirements and possible threats. If a system is to be secured it needs to be secured properly, a firewall will be of little benefit if you allow users full access to all your data. Threats can be internal as well as external, disgruntled employees are a SysAdmin's nightmare. Users able to access any website they want will bring trouble to your business, whether it be a malware infection, an employee who sits on Ebay all day or leaks your sensitive data to competitors.

Never allow employees Administrator rights (let alone superuser rights), restrict un-necessary access to the outside world, and ensure your employees know of the expectations laid upon them. Remind all users regularly, and review your security practices even more regularly.
