Insider Threat Detection
Insider threats are concerning because these attackers don’t need to penetrate your perimeter, they’re already inside it. They can be your employees, contractors, or business associates. They might be a malicious threat actor themselves, or their account might have been compromised by external attackers, giving the attackers inside access to your infrastructure and data.
In either case, the perpetrator wants to remain unnoticed, stealthily sniffing around and collecting sensitive data to exfiltrate. The attacker may be looking for confidential customer records, credit card data, research and development designs, business strategy documentation, and other sensitive business information. If compromised, this information could cause considerable damage to your company, its place in the industry, and its relationship with consumers and investors.
Legacy SIEMs generally struggle to detect insider threats.
Next-generation SIEMs provide innovative, behavior-based analytics techniques that, in conjunction with peer group analysis techniques, detect variations in normal patterns when it comes to the access and usage of internal data sources. By comparing not only historical usage, but the usage of colleagues and team members, next-generation SIEMs are able to remove the noise associated with incremental changes in user behavior and highlight concerning activity.
