Richard Bejtlich Advocates for NDR in Modern Security Operations

The Challenge of Incident Investigation

Despite having access to vast telemetry, security operations teams often struggle to answer basic questions during incident investigations. The reliance on alerts, which offer limited information, is insufficient for thorough investigations that require defensible evidence.

Implications of the Mythos Era

The so-called 'Mythos Era' is characterized by rapid vulnerability discovery, making alerts less effective. As automation increases, SecOps teams need validated evidence of live threats rather than just raw data, which is critical for informed decision-making.

The Role of Network Detection and Response

Bejtlich's publication, 'NDR Essentials: A Practical Guide to Network Detection and Response', provides insights on leveraging NDR to enhance threat hunting and investigations. It serves as a foundational resource for teams seeking to adapt to current security challenges.

Shifting Focus to Interdiction

Bejtlich proposes that rather than solely focusing on preventing attacks, security programs must address the entire attack process. This shift emphasizes the importance of identifying and disrupting malicious activities before they culminate in significant breaches.

The Importance of Proactive Security Measures

Effective security strategies require containment and isolation of threats post-compromise but pre-breach. By focusing on active disruption of threats, organizations can better manage vulnerabilities and protect critical assets from attackers.
