Identify and unlock adversary's information
Cyber threat intelligence (CTI) is the knowledge and actionable insights derived from collecting and analyzing information about existing or emerging cyber threats. This intelligence helps organizations understand the who, what, where, when, why, and how of potential attacks.
Types of CTI
Strategic: High-level information about the overall threat landscape, including trends, motivations, and geopolitical factors.
Operational: Real-time information about ongoing attacks and campaigns, including indicators of compromise (IOCs) and tactics, techniques, and procedures (TTPs).
Tactical: Specific details about attack methods, tools, and techniques used by threat actors.
Learn about Intelligence Lifecycle
1. Planning and Direction:
Defining Intelligence Requirements (IR): Identifying the organization's specific needs and priorities regarding threat intelligence. This involves understanding the organization's assets, vulnerabilities, and potential threats.
Establishing intelligence goals: Setting clear objectives for the CTI program, such as improving incident response time, reducing attack surface, or enhancing threat detection capabilities.
Identifying data sources: Determining the relevant sources of threat information, including open-source intelligence (OSINT), commercial threat feeds, industry reports, and internal security data.
2. Collection:
Gathering data from various sources: Utilizing the identified sources to collect raw data on potential threats, including threat actor profiles, malware samples, vulnerability reports, and attack indicators.
Prioritizing data collection: Focusing on the most relevant and reliable sources to ensure the quality and accuracy of the intelligence.
3. Processing:
Transforming raw data into usable formats: Converting the collected data into a standardized format for efficient analysis and interpretation. This may involve data normalization, deduplication, and enrichment.
Filtering irrelevant information: Removing noise and irrelevant data to focus on the most critical threats and indicators.
4. Analysis and Production:
Evaluating the credibility and reliability of the data: Assessing the source and context of the information to determine its accuracy and relevance.
Identifying patterns and trends: Analyzing the processed data to uncover relationships, trends, and potential attack vectors.
Developing actionable intelligence: Transforming the analyzed data into specific, actionable insights that can inform security decisions and strategies.
5. Dissemination:
Sharing intelligence with relevant stakeholders: Distributing the actionable intelligence to the appropriate individuals and teams within the organization, such as security analysts, incident responders, and executives.
Tailoring intelligence reports: Providing clear, concise, and relevant information based on the specific needs and roles of the recipients.
The cyclical nature of this process ensures that threat intelligence remains relevant and actionable, allowing organizations to stay ahead of emerging threats and continuously improve their defenses.
DON'T FORGET....
Feedback and Evaluation:
Refining intelligence requirements and processes: Continuously adapting the CTI program based on feedback, changing threats, and evolving organizational needs.
Assessing the effectiveness of the CTI program: Evaluating the impact of the intelligence on the organization's security posture and identifying areas for improvement.
