When it comes to protecting your Data and Network assets, Organizations continue to spend an exceptional amount of time and money to secure from external attacks; however, insider threats are becoming a key cause of data exposure. Based on survey from Small Businesses security experts have found that insider incidents account for more than 60 percent of all data breaches; however, many organizations don’t report insider attacks out of fear of business loss and damage to their reputation.
Insider threats come in two forms. An authorized insider threat is someone who misuse their rights and privileges, either accidentally, deliberately or his credentials were stolen. An unauthorized insider is someone who has connected to the network behind the perimeter defenses. This could be someone who plugged into a jack in the lobby or a conference room, or someone who is using an unprotected wireless network connected to the internal network. Insider attacks can lead to data loss or downtime, so it is as important to monitor activity in your network as activity at the perimeter. To have effective Network Security strategy, first, identify the main threats that your company currently faces.
Historically, the data breaches that make the news are typically carried out by outsiders. Outsider threats are generally the threats that have been addressed with traditional security measures. It’s the threats that originate from inside that are much more difficult to prevent and detect using one-size-fits-all security measures.
