What does Threat Intelligence do?
Threat Intelligence plays a crucial role in enhancing the cybersecurity measures of organizations by providing valuable insights and information about various types of attacks.
It assists in understanding the potential risks posed by these attacks and suggests effective defense strategies to counter them.
Moreover, threat intelligence also aids in mitigating ongoing attacks, enabling organizations to promptly respond and minimize the damage caused. For organizations that have adopted software-defined networking (SDN), threat intelligence becomes even more crucial.
SDN allows the flexibility of reconfiguring network infrastructure swiftly, based on the specific types of cyber threats identified through threat intelligence.
This proactive approach empowers organizations to efficiently safeguard their networks and systems against potential attacks. In order to gather comprehensive threat intelligence, an organization’s IT department may undertake various methodologies and techniques.
This can involve conducting in-depth research, monitoring suspicious activities, and analyzing data related to cyber threats.
However, organizations may also opt to rely on external threat intelligence services, which specialize in collecting, analyzing, and disseminating threat-related information.
These services not only provide valuable intelligence but also offer guidance on implementing robust security practices. Overall, threat intelligence serves as a proactive defense mechanism for organizations, empowering them to stay one step ahead of cybercriminals.
By leveraging the insights and recommendations provided by threat intelligence, organizations can strengthen their security posture and protect their valuable assets from the ever-evolving landscape of cyber threats.
Why Is Threat Intelligence Important?
The cybersecurity industry is facing numerous challenges, including persistent and clever threats, a large amount of data that is often irrelevant, a shortage of skilled professionals, and a growing range of attack surfaces.
Organizations struggle to incorporate threat data into their networks and often don’t know how to handle the excess information, which adds to the workload of analysts who lack the necessary tools to prioritize and ignore certain data.
A threat intelligence solution can solve these problems by using machine learning to gather and process data, integrating with existing solutions, gathering unstructured data from various sources, and providing context on indicators of compromise and threat actor tactics.
Threat intelligence is actionable, timely, contextual, and understandable for decision-makers.
Types of threat intelligence
There are four types of threat intelligence – strategic, tactical, technical, and operational – that are necessary for creating a well-rounded threat assessment.
Strategic Threat Intelligence
This analysis provides a summary of potential cyber attacks and their potential impacts for people who are not familiar with technology, as well as stakeholders and decision-makers. The analysis is based on in-depth research and examines emerging risks and trends from various countries.
It is presented in different formats such as white papers, reports, and presentations to give a broad understanding of the threats that an industry or organization may face.
Tactical Threat Intelligence
Tactical intelligence offers information on the tactics, techniques, and procedures used by threat actors. It is meant for individuals responsible for safeguarding IT and data resources. It provides insights on potential attacks and the most effective ways to protect against or reduce their impact.
Technical Threat Intelligence
This information discusses the signs that suggest the beginning of an attack, including activities like gathering information, preparing weapons, and executing the attack through methods like phishing and social engineering.
Technical intelligence is crucial in preventing social engineering attacks, but it needs to be constantly updated as hackers adapt their tactics to new situations.
Operational Threat Intelligence
This approach collects information from different sources like chat rooms, social media, antivirus logs, and past events to predict future attacks.
Data mining and machine learning are used to process large amounts of data in multiple languages. Security teams use this information to make changes to controls and improve response times.
Who Can Benefit from Threat Intelligence?
Threat intelligence is often seen as something only for highly skilled analysts, but in reality, it can benefit all security teams and organizations, regardless of their size.
If threat intelligence is not integrated into every aspect of a security team, many people who could benefit from it will not have access to it when they need it.
Security operations teams often struggle to handle the numerous alerts they receive. By integrating threat intelligence with existing security solutions, these teams can automatically prioritize and filter alerts and threats.
Additionally, vulnerability management teams can better prioritize vulnerabilities with the help of external insights and context provided by threat intelligence.
Furthermore, threat intelligence enhances fraud prevention, risk analysis, and other important security processes by providing a comprehensive understanding of the current threat landscape, including valuable information on threat actors and their tactics sourced from various data sources on the internet.
Key Aspects of Threat Intelligence
