Why Log Collection Still Matters: Getting the Basics Right in a Zero Trust World

In the era of sophisticated cyber threats and complex IT environments, the shift toward Zero Trust architecture is no longer optional—it’s essential. But as organizations rush to adopt advanced frameworks and AI-driven security solutions, many overlook the foundational layer of all effective security strategies: log collection.

Without comprehensive, high-fidelity log data, even the most advanced Zero Trust initiatives are rendered ineffective. This paper explores why log collection still matters—perhaps more than ever—and outlines how organizations can get the basics right to build a resilient cybersecurity posture that aligns with the principles of Zero Trust.

Introduction: The Zero Trust Imperative

Zero Trust is a strategic approach to cybersecurity that eliminates the assumption of trust. Based on the principle of “never trust, always verify,” Zero Trust requires continuous authentication, strict access controls, and real-time threat detection across users, devices, and systems.

However, implementing a Zero Trust model isn’t just about adopting new tools—it requires complete visibility into your network activity. This visibility starts with effective log collection, aggregation, and analysis.

Why Log Collection Is Still Foundational

1. Visibility and Context Are Non-Negotiable

Zero Trust is driven by continuous verification. Log data provides the forensic trail necessary to:

Validate access attempts
Monitor lateral movement
Detect anomalous behavior
Investigate incidents post-breach

Without detailed logs, it’s impossible to determine who did what, when, where, and how.

2. Data is the Fuel for Detection and Response

Security tools such as SIEMs, SOAR platforms, UEBA systems, and XDR solutions all rely on log data as the source of truth. If log collection is inconsistent, incomplete, or delayed, it leads to:

False negatives (missed attacks)
Slower mean time to detection (MTTD)
Inaccurate threat modeling

3. Compliance Still Requires It

Log retention is not just a security best practice—it’s a regulatory requirement in most industries. Frameworks such as:

ISO 27001
NIST 800-53
PCI-DSS
HIPAA
APRA CPS 234 (AU)
require auditable logs to prove due diligence and enable incident response.

The Challenges of Modern Log Collection

As environments grow more complex—spanning cloud, on-prem, hybrid, containers, and SaaS apps—log collection faces several challenges:

Getting the Basics Right in a Zero Trust World

1. Comprehensive Coverage

Ensure logs are collected from all key sources:

Endpoints (Windows, Linux, macOS)
Cloud platforms (AWS, Azure, GCP)
SaaS apps (M365, Salesforce)
Firewalls, proxies, and network appliances
Identity providers (Okta, Azure AD)

2. Log Normalization and Correlation

Implement tools that:

Normalize disparate log formats
Correlate across sources
Enrich with contextual metadata

This enables accurate behavior analysis and threat detection.

3. Intelligent Storage and Replay

Use solutions that:

Compress and deduplicate log data
Tier storage (hot, warm, cold) to balance cost and accessibility
Enable replay to SIEMs/XDRs for historical investigation without re-collection

4. Support for Open Standards and Integration

Avoid vendor lock-in by using tools that:

Support industry-standard formats (e.g., syslog, JSON, CEF)
Integrate via native APIs into SIEMs, SOARs, and cloud-native platforms

Ensure future-proof interoperability

Case in Point: Log Collection in Recent Attacks

Recent breaches highlight the value of long-term log storage and real-time collection. In many cases, delayed detection was partly attributed to incomplete or short-lived logs, making root cause analysis and containment more difficult.

Organizations with extensive log trails could:

Identify patient zero
Trace lateral movement
Close vulnerabilities before further exploitation

With Snare, organizations don’t have to choose between visibility and affordability.

Conclusion: Don’t Skip the Fundamentals

In a Zero Trust world, you can’t secure what you can’t see. Advanced frameworks and automation are powerful, but they’re only as good as the data they ingest. Log collection is not a checkbox—it’s the foundation of detection, response, and resilience.

To build a truly Zero Trust-ready architecture:

Start with logs
Invest in reliable, scalable collection
Prioritize context, retention, and replayability

Because when the next incident happens—and it will—logs may be the only window into what went wrong, and how to fix it.
