What Makes Identifying Insider Threats Challenging
While identifying unpatched machines and exploitable software is straightforward, when it comes to identifying insider threats, the process is anything but easy.
The Walls are Gone
In today’s work-from-home environment, employees can work anywhere and anytime. While this flexibility increases employee satisfaction, it makes it harder for security teams to know when a legitimate user is displaying signs of going rogue.
Understanding Normal
To know when a trusted employee's actions are abnormal, indicating an insider threat potential, you must first understand what normal behavior is for every employee. To define normal, you need technology capable of learning normal, which some security teams do not have.
Unreliable Automation
If security teams can identify the normal and thus the abnormal and potential insider threat, they need to take consistent response actions fast. Unfortunately, without the right technology, responses will be manual and slower.
How to Protect Against Insider Threats
A multi-layer security approach gives your team the best chance to detect and mitigate Insider Threats quickly.
Endpoint
Protection
You need to gather information from the user's endpoint to identify normal. Additionally, if you need to take response actions in response to suspicious activity, you must have a way to isolate an endpoint, which endpoint protection can give you.
Network
Protection
99% of all attacks will traverse your network at some point. Network protection products like NDRs are great ways to detect if a user moves an abnormal amount of data across the network, indicative of a rogue user.
Identity Management &
CASB
A least-privilege approach to user provisioning can ensure that if an insider goes rogue, the user will face some challenges navigating the network freely. Additionally, Cloud Access Security Brokers (CASB) are essential to administer corporate identity policies across all your cloud environments.
User Entity &
Behavior Analytics
While you gather data from endpoints and servers with your endpoint protection, the heavy lifting when identifying normal and abnormal behavior occurs in a User and Entity Behavior Analytics (UEBA) solution. Understanding normal is critical to identifying insider threats. Without this layer of protection, security teams will always be recovering from an attack rather than stopping it from happening.
Security
Analytics
While the impact of a rogue user is evident after the fact, there are opportunities to detect potential signs of a user going rogue when actively monitoring and correlating user and entity behaviors and flagging suspicious activities.
Automated
Response
With the previous protection layers in place, you need a way to respond to a detected threat at scale quickly. Using an automated response product like a SOAR can be the difference between stopping a rogue insider before they do harm and a significant data leak.
