Finally, determine when users stop doing their jobs. I'm always amazed when I hear that IT is the last to know when a user leaves a job or changes position. This is one of the greatest security risks that exist in the networking world. If IT doesn't know that a person is no longer with the company, it can't change the settings that would block access to the network.

This is where your relationship with HR and business unit managers comes in handy. Develop an automated form that both groups can access from anywhere that immediately alerts you to hirings, firings and changes in position. This information should bubble up to the top of whatever IT is working on at the time and take precedent over all other projects. For instance, if someone in accounting decides to take a job with the sales team, he should immediately have his access to company financials revoked. Or if a user with a corporate mobile device is let go, you'll know to remotely erase data off that device.

Knowledge is a powerful tool. The insight you will gain from meeting face-to-face with your colleagues is sure to improve your ability to protect the network, as well as provide remote users with the appropriate tools to do their jobs.
