Introduction
Insider threats are a growing concern for every organization — one that is increasingly difficult to manage using conventional security technologies. According to Ponemon’s 2022 Cost of Insider Threats Global Report:
1. Insider threats have increased in both frequency and cost over the past two years.
2. Credential thefts have almost doubled in number since 2020.
3. Insider threats caused by careless or negligent employees are the most prevalent.
4. The report benchmarked 278 organizations and identified:
* 5,803 total number of insider incidents
* At a total average annual cost of $15.3 million
Unlike other types of security threats, insider threats are complicated because only a few are caused intentionally, and they typically involve valid credential use. Beyond full- and part-time employees, insiders include contractors, vendors, customers, interns, and others who can be working on site or remote.
Frequently they’re authorized to access some part of your network, but too often their access and permissions (not to mention activities) aren’t being effectively managed by the organization’s security team. When you consider all these risks, it’s easy to see why insider threats require a comprehensive cybersecurity strategy.
This guide was created to reduce confusion regarding what insider threats are and how your organization can defend itself against them. Topics include:
- Defining insider threats
- Why they need detection
- The value of simulation and security training
- A modern approach to insider threat detection
- Real-world examples of insider threat attacks
- Insider threat activities and data feed detection points
- Applying data science to insider threat evaluation
- Insider threat use cases
- What to consider when defending against insider threats
- Advanced best practices for insider threat programs
Our hope is that this guide will help organizations better understand what they must consider concerning insider threats. It also outlines what they can do to improve their overall security posture with faster, easier, and more accurate insider-threat detection, investigation, and response (TDIR).
