    Study Notes

    Module 3: Threat Intelligence

    • This module focuses on evaluating threat intelligence sources.
    • Information sources are used to communicate emerging network security threats.
    • Various threat intelligence services are described.

    3.1 Information Sources

    • SANS Institute resources are largely free and include the Internet Storm Center (early warning system), NewsBites (weekly security news digest), @RISK (weekly digest of newly discovered attack vectors), Flash security alerts, and a Reading Room with over 1,200 research papers.
    • SANS develops security courses.
    • MITRE maintains a list of CVE (Common Vulnerabilities and Exposures) used by security organizations.
    • FIRST is a security organization that brings together incident response teams of various organizations (government, commercial, educational) to share information and coordinate efforts.
    • SecurityNews aggregates the latest security news, alerts, and vulnerabilities.
    • (ISC)² provides vendor-neutral education and career services to over 75,000 professionals.
    • CIS is a focal point for cyber threat prevention, protection, response, and recovery for governments through MS-ISAC.

    Network Intelligence Communities (cont.)

    • To remain effective, cybersecurity professionals must:
      • Stay up-to-date on the latest threats (subscribe to real-time feeds, security websites, blogs, podcasts).
      • Continue to upgrade skills (attend security training, workshops, conferences).
    • Network security has a steep learning curve and requires ongoing professional development.

    Cisco Cybersecurity Reports

    • Cisco Annual Cybersecurity Report and the Mid-Year Cybersecurity Report help security professionals stay abreast of the latest threats.
    • These reports provide updates on security preparedness, analysis of top vulnerabilities, factors behind attacks (adware, spam).
    • Analysts should subscribe to these reports to understand threat actor tactics and learn how to mitigate these attacks.

    Security Blogs and Podcasts

    • Another way to stay updated on threats is through blogs and podcasts.
    • Blogs and podcasts provide advice, research, and mitigation techniques.
    • Cisco provides security blogs and podcasts from experts and the Cisco Talos Group.
    • Subscribe to receive notifications of new content, and podcasts can be played from the internet or downloaded.

    Lab - Evaluate Cybersecurity Reports

    • Lab objectives:
      • Part 1: Research Cyber Security Intelligence Reports
      • Part 2: Research Cyber Security Intelligence Based on Industry
      • Part 3: Research Cyber Security Threat Intelligence in Real Time

    3.2 Threat Intelligence Services

    • Threat intelligence services allow the exchange of threat information (vulnerabilities, IOCs, mitigation techniques) for personnel and security systems.
    • As threats emerge, threat intelligence services create and distribute firewall rules and IOCs to subscribed devices.
    • Cisco Talos Threat Intelligence Group is one such service.

    Cisco Talos (cont.)

    • Cisco Talos is a major commercial threat intelligence team comprised of experts and researchers.
    • Its goal is to protect enterprise users, data, and infrastructure from active adversaries.
    • The team collects information about active, existing, and emerging threats.
    • It provides comprehensive protection (against attacks and malware) to subscribers.
    • Cisco Security products can use real-time security solutions.
    • It provides free software, services, resources, and data.
    • It maintains security incident detection rule sets for Snort.org, ClamAV, and SpamCop network security tools.

    FireEye

    • FireEye offers security services using a three-pronged approach (security intelligence, expertise, technology).
    • It provides SIEM and SOAR with the Helix Security Platform, leveraging behavioral analysis and threat detection.
    • Helix is a cloud-hosted platform combining diverse security tools and threat intelligence.
    • FireEye blocks attacks across web, and email vectors and latent malware.
    • It addresses all stages of the attack lifecycle with a signatureless engine for zero-day threat detection.

    Automated Indicator Sharing

    • The U.S. Department of Homeland Security (DHS) offers a free service called Automated Indicator Sharing (AIS).
    • Enables real-time exchange of cyber threat indicators (e.g., malicious IP addresses, phishing emails) between the U.S. Federal Government and the private sector.
    • Creates an ecosystem where threats are immediately shared with the community for protection.

    Common Vulnerabilities and Exposures (CVE) Database

    • The United States government sponsored the MITRE Corporation to create and maintain a catalog of known security threats (CVE).
    • The CVE serves as a dictionary for cybersecurity vulnerabilities, using unique CVE Identifiers to facilitate data sharing.

    Threat Intelligence Communication Standards

    • Network organizations and professionals share information to increase knowledge of threat actors and assets.
    • Several open standards facilitate cross-platform communication.
    • Three common standards are Structured Threat Information Expression (STIX), and Trusted Automated Exchange of Indicator Information (TAXII), and CybOX.
    • STIX is used for exchanging threat information between organizations.
    • TAXII facilitates the communication of CTI (Cyber Threat Intelligence) over HTTPS.
    • CybOX specifies events and properties of network operations to support many cybersecurity functions.

    Threat Intelligence Communication Standards (cont.)

    • Open standards facilitate standardized cyber threat intelligence information exchange.
    • The Malware Information Sharing Platform (MISP) is an open-source platform for sharing IOCs for newly discovered threats.
    • MISP is supported by the EU and is used by over 6,000 organizations globally.
    • MISP enables automated IOC sharing between people and machines using STIX and other export formats.

    Threat Intelligence Platforms

    • Multiple threat intelligence sources can be very time-consuming to access and use.
    • Threat Intelligence Platforms (TIPs) centralize the collection of threat data from various sources and formats.
    • Three main types of data are IOCs, TTPs, and reputation information for internet destinations/domains.
    • TIPs aggregate and present threat intelligence data in a comprehensible and usable format.

    Threat Intelligence Platforms (cont.)

    • Organizations can contribute to threat intelligence by sharing intrusion data (typically automated).
    • Threat intelligence services utilize subscriber data to keep current with emerging threats.
    • Honeypots are simulated networks/servers that attract attackers.
    • Gathering data from honeypots can be beneficial, but also presents potential risks.
    • Cloud-hosted honeypots isolate them from production networks.

    Lab – Identify Relevant Threat Intelligence

    • Lab objectives:
      • Part 1: Research MITRE CVEs
      • Part 2: Access the MITRE ATT&CK Knowledge Base
      • Part 3: Investigate Potential Malware

    3.3 Threat Intelligence Summary

    • Many organizations provide network intelligence.
    • Keep up-to-date on threats and continuously improve skills.
    • Utilize resources like the Cisco Annual and Mid-Year Cybersecurity Reports.
    • Use security blogs and podcasts for threat information.
    • Threat intelligence services allow exchange of threat information among personnel and security systems.
    • These services create firewall rules and IOCs as threats emerge.
    • Cisco Talos and FireEye are examples of these services.
    • FireEye uses a three-pronged approach combining security intelligence, expertise, and technology.
    • The U.S. Department of Homeland Security offers Automated Indicator Sharing (AIS)
    • The MITRE Corporation maintains a catalog of known vulnerabilities and exposures called CVE.
    • STIX, TAXII, and CybOX are key threat intelligence communication standards.
