Insider Threats

One of the biggest problems of insider threats is the delay in detection, says a new report.

Along with detection, managing, and fighting insider threats is challenging, especially in the case of a tight budget and insufficient tools. According to the latest report from the Bitglass 2020 Insider Threat Report, the average cost of remediating an attack ranges from $100,000 to $2 million. Even if the costs are under $100,000, they can add up in the face of multiple attacks.

As more employees are now working from home, it has increased the possibility of increasing insider threats that lead to data loss, business slowdowns, legal liabilities, and reputation damage.

Typically, insider threats come from angry or careless current employees, or former employees who still have access to company networks. Most of the time, it takes around a week to detect an insider attack and more than a week to recover from it.

A report from Gartner, earlier this year found that by 2023, 60% of large enterprises will have well-defined incident response scenarios for insider threats, 20% up from the current state. It is essential for organizations to identify the potential risky behaviours and map them against potential solutions. The mitigations may differ by organization; however, common scenarios like installing unsanctioned software, failing password attempts and attempting access to other employee accounts, will still remain the same.
