🔍 Threat Intelligence Basics
Learn how organizations use information about threats to improve defenses and prioritize security efforts.
📰 The Weather Forecast Analogy
Before traveling, people often check:
- Weather Forecasts
- Traffic Conditions
- Road Closures
Threat intelligence serves a similar purpose.
It helps organizations understand what risks may be approaching.
📖 What Is Threat Intelligence?
Threat Intelligence is:
Information About Threats Used To Improve Decisions
Good intelligence helps security teams focus on what matters most.
📚 Types Of Threat Intelligence
Business Risk & Industry Trends
👨💻 Operational Intelligence
Campaigns & Threat Activity
🔧 Tactical Intelligence
Techniques & Behaviors
📊 Technical Intelligence
IPs, Domains, Hashes
🚩 Indicators Of Compromise (IOCs)
Security teams may monitor:
- Suspicious IP Addresses
- Malicious Domains
- File Hashes
- Known Bad URLs
- Suspicious Email Senders
These indicators help identify known threats.
🎯 TTPs Matter More
Mature defenders focus heavily on:
Tactics, Techniques & Procedures
Why?
IPs change.
Domains change.
Attacker behavior is often more valuable to understand.
🗺 MITRE ATT&CK Framework
Many security teams use:
MITRE ATT&CK
To categorize and understand adversary behaviors.
Examples:
- Credential Access
- Persistence
- Discovery
- Lateral Movement
- Defense Evasion
📡 Threat Intelligence Sources
- Vendor Reports
- CISA Advisories
- Security Researchers
- Cloud Providers
- Industry Information Sharing Groups
- Security Communities
Not all intelligence has equal value.
👨💻 Tech Lead Example
Suppose your SaaS platform uses:
- Laravel
- AWS
- MySQL
- Cloud APIs
Threat intelligence may reveal:
- Actively exploited vulnerabilities
- Credential theft trends
- Cloud security risks
- New phishing campaigns
This helps prioritize defensive actions.
⚠️ Common Mistake
Many organizations collect:
- Threat Feeds
- Reports
- Indicators
But never use them.
Intelligence only becomes valuable when it influences decisions.
⚙️ Intelligence Workflow
⬇️ 🔍 Analysis
⬇️ 📊 Risk Assessment
⬇️ 🛡 Security Action
📋 Security Review Questions
- How do we track emerging threats?
- Do we monitor vendor advisories?
- How quickly do we act on critical intelligence?
- Do we understand threats targeting our industry?
- Can intelligence influence security priorities?
🏆 Key Lesson
Threat intelligence is not about collecting information.
It’s about making better decisions.
Information + Action = Intelligence
🎯 Zero Trust Security
Learn why modern organizations are moving away from “trust but verify” and toward “never trust, always verify.”
