10 articles
Incident response is the structured process of detecting, containing, and recovering from a security breach. These guides walk through the NIST lifecycle, evidence preservation, the memory-before-shutdown rule, and what to do in the critical first hours after a data breach.
The 3-2-1 Backup Strategy: Ransomware-Resistant Backups
What 3-2-1 means, why ransomware forced the 3-2-1-1-0 update, how immutability and air gaps work, and the restore testing that decides whether any of it was real.
CVSS vs EPSS: Which Score Should Drive Your Patching
CVSS scores how bad a vulnerability would be. EPSS estimates how likely it is to be exploited in the next 30 days. They answer different questions, and using the wrong one produces an unclearable queue.
Digital Forensics Basics: Acquisition, Order of Volatility, Analysis
How a forensic examination works: chain of custody, the order of volatility, memory and disk acquisition with verification hashes, the Windows artifacts that answer common questions, and anti-forensics.
Sigma Rules: Portable Detections for Any SIEM
How Sigma rules work: the YAML structure, log sources, the detection block and condition syntax, field modifiers, correlations, and converting one rule into Splunk, Sentinel or Elastic queries with sigma-cli.
The Vulnerability Management Lifecycle: From Scan to Verified Fix
The six stages of vulnerability management: inventory, discovery, prioritization, remediation, verification and reporting, with the prioritization math that beats patching by CVSS score alone.
SIEM: Log Collection, Correlation and Detection
How a SIEM works end to end: collection, parsing, enrichment, correlation and alerting, what it costs, how it differs from EDR, XDR and SOAR, and why most deployments fail on tuning rather than technology.
Windows Event IDs: The Highest-Signal Logs for Detection
A defensive reference to the Windows Security and Sysmon event IDs that matter most for detection: what each ID means, why it matters, and an example use.
Cybersecurity for Small Business: The Essential Checklist
43% of cyberattacks target small businesses. Here's the no-budget-required security checklist that covers the attacks you'll actually face.
Incident Response 101: From Detection to Recovery
A practical guide to the NIST incident response lifecycle, preparation, detection, containment, eradication, recovery, and lessons learned.
What to Do After a Data Breach: Step-by-Step Response
Your data was exposed in a breach. Here's exactly what to do in the first 24 hours, the first week, and long-term to protect yourself.
