Suggested October 2023 A Quick Glance Of How Threat Intelligence Works

Introduction to Threat Intelligence

The information used by the organization to understand the threats targeting them or the possibility of threats in the future is called threat intelligence. The threats trying to misuse the organization’s valuable resources can be identified and prevented using this information. Cyber threats are terrifying and can damage the reputation and identity of the organization. A strong defense against these threats can be built with the help of threat intelligence. It can defend the threats effectively. It is important to understand how cyber threat works to choose the right solutions.

The following objectives can be achieved by implementing threat intelligence:

Staying up to date with daily emerging threats, methods, weaknesses, targets, etc., that are huge in volumes.

Make us more proactive against the threats that are about to happen in the future.

Informing the users, stakeholders, and leaders about the latest threats and their effects on their businesses.

How Does it Work?

Threat intelligence is the output product of a cycle of data collection, processing, and analysis that consists of six parts. An intelligence program becomes effective when it is iterative in nature, becoming more refined in each iteration. This can be produced effectively if the use cases are identified and the objectives are defined.

The steps to maximize the value of threat intelligence are:

1. Planning and Direction 2. Collection

The new requirements that are set up in the first stage must be fulfilled in this step by gathering the raw data. The data can be collected from a variety of sources. Network event logs and responses of the past incident’s records are the internal sources of data. Open web, dark web, etc., are the external sources of data. Threat data can be IOC’s list like malicious IP addresses, domains, etc., but there can also be personal identity information of customers, text from sources of news or social media that are vulnerable.

3. Processing

After it has been collected, the data must be sorted, organized with tags of metadata, and redundant information, or false positives and negatives, must be filtered out. The data collected by organizations are too huge to be processed by humans; hence data collection and processing must be automated.

4. Analysis 5. Dissemination

This step does the distribution of the output product to its consumers. Right people at the right time must be available for the threat intelligence to be in action. There must be tracking of threat intelligence so that there is a continuation from one cycle of intelligence to another cycle of intelligence, and learning is maintained. The intelligence cycle is tracked using security systems, and they are integrated with ticketing systems. Multiple people from different teams accept, write up, and review the tickets whenever new intelligence requests come up.

6. Feedback

When the intelligence cycle becomes a full circle going back to the initial planning phase is the final step in the intelligence cycle. When the output product is ready, the person who requested the product reviews it and checks if there are answers to all the questions asked. This makes for the objectives of the next threat intelligence cycle.

Benefits of Threat Intelligence

The threats faced by the organization can be determined immediately.

Decision-making by addressing the vulnerabilities and the order in which the vulnerabilities must be addressed can be determined by the information gained using threat intelligence.

Emerging threats information can be accessed.

The activities of cyber-criminals can be tracked using threat intelligence.

If the organization or a brand is mentioned in social media can be monitored.

The online channels of communication are monitored for proofs of activities of cybercrime.

Checking the strength of the internet in the organization to determine if it’s vulnerable.

Security breaches can be identified and prevented by using it.

Fraud and theft can be prevented and minimized by incident monitoring.

Threat management provides the information required for the risk management of the organization.

Drawbacks

The defenders are unable to act on security incidents with the highest priority because of signal-to-noise problems.

The attackers are filing false threat reports to mislead the intelligence systems.

Most of the data gathered by security people are duplicate in nature, thereby wasting time and effort.

Security systems must match the attack speeds.

Data can be turned into intelligence if and only if there is the identification of patterns.

Conclusion – Threat Intelligence

Modern security teams are driven by threat intelligence because it gives in-depth knowledge about threats, thereby protecting the organization from all kinds of attacks. Organizations recognize the value of threat intelligence, and studies show that organizations investing in intelligence are increasing day by day.
