You Can’t Defend What You Can’t See – Seize the Breach

Every day, organizations around the world are struggling with cyberattacks. They start as incidents, often result in intrusions, and, for some, result in a breach.
Attackers don’t take vacations and they don’t discriminate. They target organizations large and small, hoping to disrupt operations, steal data, or get paid a ransom. On the other side of these adversaries are organizations hoping to stay out of the headlines while managing a constant battle. It’s certain that these organizations have security technologies in place that purport to stop cyberattacks. So, why do breaches continue to occur?
Every security solution has its blindspots — things they can’t see. Those dark corners are where threats can lurk undetected. But there’s good news: SOC teams can shine a light on those blindspots and get insights into where risk and potential threats exist in your environment.
Know thy environment, know thy enemy
With the dizzying number of emerging threats and security challenges, the security practitioner’s mentality must shift from a preventive to a proactive one — an “assume breach” mindset — looking at behaviors rather than relying solely on indicators of compromise (IoCs), signatures, and rules.
Behavior provides a lot more dependable, meaningful, and practical information. Knowing the behaviors of each user and asset that exists within your environment, and then baselining it, is what will help you stay ahead of malicious actors and compromised insiders. You need to know what normal looks like, so that you can quickly detect and respond to any anomalies.
Legacy tools can’t keep up
Legacy Security Information and Event Management (SIEM) tools were not designed with behavioral analytics in mind. They are reactive, and rely on static, outward-facing detection rules that can’t adapt to today’s attack landscape. They don’t have the ability to understand what normal behavior looks like, which allows adversaries to gain access, move laterally, and dwell in your systems undetected.
A light at the end of the tunnel
There is no perfect solution, no silver bullet. However, next-generation SIEM tools can help you to see into the top five blindspots:
- Compromised user credentials
- Compromised system/host/device
- Rogue insiders
- Lateral movement
- Service account misuse
You can’t defend what you can’t see. Exabeam promotes an inside-out approach, using data science to analyze user and asset behavior for suspicious things like unusual logins, abnormal network activity, or irregular credential use. When we find it, we increase the risk score. When the score exceeds a threshold, we flag it for review. When you combine these insights with machine learning-assisted alert triage, automated investigations, and response workflows, SOC teams become more productive — and more effective — empowering you to Seize the Breach.
