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
