Intro to the SOC Visibility Triad

Thread
Data aggregated from these three core security realms can give the SOC an overall view of the most critical activity across the entire environment, as well as important clues to the earliest and strongest indicators of a pending compromise.

Here is a breakdown of each pillar, the data it offers, and how it adds to the overall visibility of security threats across the technology environment.

Stop malicious behavior in its tracks with User and Entity Behavior Analytics (UEBA) and Logging Data

In 2019, 80% of hacking-related breaches were due to compromised credentials, according to Verizon’s 2019 Data Breach Investigations Report. Whether it’s poor passwords or credentials stolen through phishing or other means, user data comes up as a top security issue year after year. Baselining normal user behavior in your environment allows you to more quickly recognize abnormal behavior, such as potential bad actors, so you can identify compromises early on.

Today’s SIEMs should offer features such as visual log search, auto log structuring, and intuitive log parsing capabilities to make it easy to investigate and triage incidents and create custom alerts when needed.

Find threats early with network traffic analysis (NTA) data

Continuously monitoring network traffic is a great way to detect intrusions across the network and minimize an attack’s reach. But knowing which alerts the team should focus on is easier said than done. The key to NTA is reducing the data volume while maintaining access to critical data so that investigations, forensic activities, and custom rule creation can all take priority. With the right system in place, analysts can ensure they maintain continuous visibility across the network while gaining the ability to recognize compromises quickly and being able to trace potential attackers’ steps across systems and applications.

Recognize the first signs of an attack with endpoint detection and response (EDR) data

Endpoint compromises give attackers access to sensitive information in addition to potential protocols or credentials that can give them further access to the network or more privileged accounts. In order to identify which assets were specifically targeted in an attack, your team needs endpoint scanning and alerts. Real-time endpoint detection and response is a critical piece of getting the visibility to recognize an attack at its first sign.

Unfortunately, there are several obstacles security professionals have to overcome to achieve visibility in all three pillars. Many point solutions may fall short of providing full visibility or cloud the data with extra noise or complexity. Some SIEM software providers require tedious configuration and alert tuning, meaning they can’t provide the visibility necessary without more time and work, which most SOCs simply don’t have.
