What is security threats and explain its type.

The Computer Security Institute (CSI) conducted a study on network security threats and security breaches and discovered that, out of all of the companies polled, 70 percent have had some type of security breach. These security threats can be categorized as external versus internal, and unstructured versus structured.

External and Internal Threats

Security threats can come from two locations:

  • External users

  • Internal users

An external security threat occurs when someone outside your network creates a security threat to your network. If you are using an intrusion-detection system (IDS), which detects attacks as they occur, you probably will be mildly shocked at the number of probes and attacks that occur against your network daily.

An internal security threat occurs when someone from inside your network creates a security threat to your network. Interestingly, the CSI study has found that, of the 70 percent of the companies that had security breaches, 60 percent of these breaches come from internal sources. Some of these security breaches were malicious in intent; others were accidental. Therefore, you should not just be concerned about protecting the perimeter of your network, you should also aim to protect every key resource and service.
