Note: Today is week 4 of a 9-week blog series in which we are peeling back the 7 Layers of Data Security. Catch up on the series here.
#### Layer 2: Network Security
, so when used together, they can mean different things to different people. For the purpose of this discussion, we're using it to describe the process of partitioning your network so that two things happen:
- People can access the areas of the network appropriate to their job function
- Devices can only access areas of the network appropriate to their function
Basically, Network Security comes down to this: there is no reason that every department and job function should have access to every area of your network.
#### For Example ...
Tim, the office administrator, should only have access to what is relevant to his job. Cheryl, the IT Director, should have greater access to the network — but even for Cheryl, it may not be relevant to have access to everything. Unfortunately, it is entirely too common to see infrastructures where large groups of people are given complete network access. This exposes your network to threats. But to what threats exactly?
#### Why Do We Limit Access?
Two answers: rogue employees and rogue devices.
- Rogue Employees ' We segment and limit access to protect the company against both intentional malice and unintentional mistakes. There is no 100% problem-proof network. But it's your job to make it as difficult as possible for a large-scale breach to occur or mistake to happen. Each user must have only the access that aligns with their job function.
- Rogue Devices ' It's technology. It breaks. Software becomes outdated. Platforms don't sync. We also segment and limit access to individual devices to protect the company as a whole in case a device is lost, stolen, or compromised.
