    Study Notes

    Threat Intelligence

    • Threat intelligence is crucial for security professionals to stay up to date with the latest threat posts and understand potential threats to their organization.
    • Threats can come from public or private threat databases, hackers, or other sources on the internet.

    Open-Source Intelligence (OSINT)

    • OSINT is a good starting point for gathering threat intelligence from open sources.
    • Open sources include the internet, discussion groups, social media sites, and governmental organizations.
    • OSINT provides publicly available information from meetings, reports, and other sources.

    Commercial Resources

    • Commercial resources provide financial information, databases, maps, and other publicly available information.
    • These resources are valuable and can be obtained for a cost.

    Threat Intelligence Reports

    • Threat intelligence reports can be used by anyone in IT security.
    • Reports are essential for understanding threats that may apply to an organization.

    Vulnerability Databases

    • Vulnerability databases compile information from researchers and provide a summary of vulnerabilities.
    • One popular database is the Common Vulnerabilities and Exposures (CVE) database.
    • CVE is sponsored by the US Department of Homeland Security and the Cybersecurity and Infrastructure Security Agency.

    National Vulnerability Database (NVD)

    • NVD is a summary of all CVEs, providing severity scoring and patching information.
    • NVD provides a dashboard with real-time data, including new CVEs, analyzed vulnerabilities, and score distributions.

    Threat Maps

    • Threat maps provide a visual perspective of attacks, including origins and frequency.
    • Maps are created from real-time data pulled from many sources.

    File or Code Repositories

    • Repositories like GitHub can provide intelligence on potential threats.
    • Hackers may use these repositories to gather information for future attacks.
    • Misconfiguration can cause source code to be released publicly, allowing attackers to find vulnerabilities.

    Cyber Threat Intelligence (CTA)

    • CTA is a platform where members share threat information and validate threats.
    • CTA enables faster reaction to threats with higher-quality information.

    Automated Indicator Sharing (AIS)

    • AIS is a way to automate the transfer of threat information between organizations.
    • AIS uses a standardized format called STIX (Structured Threat Information eXpression).
    • TAXII (Trusted Automated eXchange of Indicator Information) is a trusted transport for transferring STIX data.

    Dark Web

    • The dark web is an overlay of the internet that requires specialized software to access.
    • It provides extensive information on hacker activities, tools, and techniques.
    • Dark web forums can be a valuable tool for gathering intelligence against attackers.

    Indicators of Compromise (IOCs)

    • IOCs are specific activities that indicate a network breach.
    • Examples of IOCs include unusual network traffic, changes in file hash values, and unusual login patterns.
    • Understanding IOCs is essential for detecting and responding to network breaches.

    Predicting Compromise

    • Analyzing large amounts of data quickly can help predict potential breaches.
    • Criteria for predicting compromise include evaluating DNS queries, traffic patterns, and location data.
    • Combining these criteria with vulnerability information can help predict potential attacks.### Threat Information Sharing
    • AIS (Automated Indicator Sharing) is a method to automate the process of sharing threat information between organizations quickly and securely over the internet.

    Standardized Format for Threats

    • STIX (Structured Threat Information eXpression) is a standardized format for representing threat information, including motivations, abilities, capabilities, and response information.

    Secure Exchange of Threat Information

    • TAXII (Trusted Automated eXchange of Indicator Information) is a trusted transport method for securely exchanging STIX data between organizations.

    Dark Web Threat Intelligence

    • The dark web is an overlay to the existing internet, requiring specialized software to access private websites.
    • The dark web provides valuable threat intelligence, including information on hacker groups, tools, and techniques used to gain network access.
    • Dark web forums can be a valuable tool for searching for intelligence on attackers.

    Indicators of Compromise (IOCs)

    • IOCs are specific activities that indicate a network may have been breached.
    • Examples of IOCs include:
      • Unusual network traffic patterns
      • Changes to file hashes
      • Unusual login patterns
      • Changes to DNS server data
      • Unusual file access patterns

    Predicting Network Compromise

    • Analyzing large amounts of data quickly can help predict potential network compromises.
    • Criteria for predicting compromises include:
      • Analyzing DNS queries and traffic patterns in real-time
      • Combining with location data to understand traffic origins
      • Identifying vulnerabilities that may be exploited
