CyberSecurity

01- What is? 

Threat Intelligence Sharing is the structured and secure exchange of cyber threat information between organizations to improve collective defense, early detection, and response capabilities.

It enables organizations to proactively defend against attacks by learning from incidents observed by others.

02- Why We need it? Objectives

• Reduce Mean Time to Detect (MTTD)

• Reduce Mean Time to Respond (MTTR)

• Enable proactive defense

• Strengthen industry-wide resilience

03- Use Case?

• Organization A detects a malicious IP used in an attack.

• It publishes the IOC to a Threat Intelligence Platform (TIP).

• Other organizations ingest the data into their SIEM or firewall systems.

• They block the IP before being targeted.

This approach is known as Collective Defense.

04- Technical Definitions

It involves sharing:

• Indicators of Compromise (IOCs)

  • Malicious IP addresses

  • Domains

  • File hashes

• Tactics, Techniques, and Procedures (TTPs)

• Threat actor information

• Exploited vulnerabilities

• Ongoing attack campaigns

05- Business Values

• Reduced financial loss

• Faster containment

• Improved compliance (e.g., ISO 27001, NIST CSF)

• Enhanced organizational reputation

06- Tools

• MISP (On-Prim/Cloud)

• ANOMALI (On-Prim/Cloud)

• Recorded Future (Cloud Only)

• Threat Connect (On-Prim/Cloud)
