Threat Intelligence

What is Threat Intelligence?

You have digital intellect when you have the skill to investigate treacherous material and deliver info on adversaries. Knowing the unauthorized programmer's identities, inspirations, and competencies is useful for detecting, preparing for, and averting invasions.

In the face of future hacking attacks, entities can use it to take a preventative, rather than reactive, stance. It is impossible to combat cyber-attacks effectively without first grasping protection flaws, danger gauges, and invasion methods. In the event of ransomware, the use of cyber threat intelligence (CTI) can aid privacy specialists in responding more quickly and containing the impairment more effectively, thus reducing costs. 

All characteristics of an institution's privacy, including those pertaining to the net and the cloud, can benefit from applying CTI.

What does CTI do?

Data acquired from it can be utilized to better prepare for these situations and lessen the likelihood of costly losses in both capital and goodwill. It is the ability to foresee and safeguard against the breaches to which an entity is likely to be subject in the future, allowing for the proactive adjustment of defense mechanisms and the avoidance of such invasions altogether.

The Importance of CTI

The assortment and examination of sensitive information is integral to any operative cyberprivacy substructure. Cyber Threat Intelligence is a package that can:

• Foil data loss: Through an organized CTI program, businesses can categorize internet-based invasion dangers and avoid data cracks from disclosing delicate data.
• Offer guidance on safety measures: It can help businesses shield themselves from future cyber attacks by examining and defining hazards, thus revealing common hacker patterns.
• Pass the word along: Hackers' intelligence grows daily. Experts in the field of cyber risk keep up with the latest threats by disseminating info about the approaches used by cybercriminals to their peers.

For Whom Is CTI Useful?

Team and group leaders in charge of privacy and risk. It is generally believed that only highly trained analysts can properly analyze threats. In reality, it improves the quality of all network security for businesses of any size.

When CTI is treated as a separate function within a larger security team, as opposed to an essential component that boosts every function, many of the individuals who would gain most from CTI do not have access to it when they need it.

Although privacy operations teams frequently struggle to keep up with the volume of signals they receive, integrating CTI with your existing security solutions can help invariably prioritize and filter these notifications. 

As a result of having access to external insights and context provided by threat intelligence, vulnerability management teams are better able to accurately prioritize the most important vulnerabilities. 

Also, CTI provides key insights on threat actors, their tactics, techniques, and practices, and more from datasets across the web, which enriches fraud prevention, risk breakdown, and other high-level privacy mechanisms.

Types of Threat Intelligence

Think of the three stages below as a sort of intelligence maturity curve. Cyber security threat intelligence context and analysis grow more nuanced and complex as it progresses; it also expands its target demographic and potentially increases in price.

1. Tactical Threat Intelligence

Issue: Companies tend to focus on isolated security risks.

Goal: Gain a broader understanding of threats in order to combat the root cause.

It is future-oriented, technical in nature, and capable of spotting relatively straightforward indicators of compromise. IOCs include things like known malicious domain names, IP addresses, URLs, and file hashes. It can be processed by computers, allowing security products to take advantage of feeds or API integration to consume the data.

It is the most straightforward to produce, and it is typically generated automatically. Because IOCs like malicious IP addresses or domain names can become obsolete in a matter of days, or even hours, this information is readily available via open source and free data feeds, but it typically has a very short lifespan.

You can get a lot of information by subscribing to intel feeds, but that doesn't help you process it or analyze the threats that matter to you strategically. Another issue is that the source might not be timely or accurate, leading to a false positive.

2. Operational Threat Intelligence

Issue: Threat actors choose effective, opportunistic, and low-risk tactics.

Goal: Campaign tracking and actor profiling to recognize the attackers.

Tech experts study their enemies in the same way that poker players study each other's habits to foresee their next moves.

There is always a "who," "why," and "how" behind an intrusion. Attribution addresses the "who" question. This "why" is referred to as motivation or intent. TTPs are what make up the "how" employed by the threat actor. When taken as a whole, they offer context, and understanding an enemy's context can shed light on their strategy, tactics, and overall success in major operations and drives. The term "operational intelligence" describes this type of understanding.

CTI for operations cannot be created by machines. There is no substitute for human analysis in transforming data into a format that can be easily utilized by customers. In contrast to tactical intelligence, which can be easily updated when a new piece of malware or piece of infrastructure is discovered, operational intelligence has a longer shelf life because adversaries are less likely to change their tactics, techniques, and procedures (TTPs).

It is best for security operations center cybersecurity experts who manage daily operations.

3. Strategic Threat Intelligence

Challenge: When the enemy is misunderstood, commercial and organizational decisions are bad.

Goal: Threat intelligence should guide company decisions and processes.

Cyber attackers rarely act alone. Geopolitical factors and danger are linked to nation-state assaults. With financially driven Big Game Hunting, cyber-crime groups are continually upgrading their strategies and should not be disregarded.

It illustrates how global events, foreign policies, and long-term local and international movements can affect an organization's cyber security.

It also informs business leaders about cyber hazards. With this knowledge, they can make cybersecurity expenditures that safeguard and support their strategic goals.

It is toughest to generate and needs human data collection and analysis and a deep understanding of cybersecurity and geopolitics. Often, strategic intelligence is provided as reports.

Threat Intelligence Lifecycle

The intelligence lifecycle is the series of steps used to develop obtainable intelligence from raw data. There are various variations of the intelligence cycle, but they all have the same end goal: to help a cybersecurity team create and implement reliable threat intelligence platforms.

One of the main obstacles to gaining useful threat intelligence is the ever-changing nature of threats, which necessitates rapid response and adaptation on the part of enterprises. The intelligence cycle is a method for coordinating efforts and assessing threats in the current environment. There are six stages to this cycle that together form a feedback loop that promotes ongoing progress:

Let's take a look at the next 6 steps:

1. Requirements

This phase of the threat intelligence lifecycle establishes the course for a given threat intelligence operation, it is of paramount importance. At this phase, the team will determine the requirements of the intelligence program's stakeholders and come to an agreement on the program's overall objectives and approach. Possible goals for the team's investigation are:

• Who the assailants are and their motivations.
• What's the assault surface.
• What steps should be done to bolster their defenses.

2. Collection

Stage two includes collecting raw data that satisfies the initial criteria. It is preferable to compile information from numerous different sources, both internal and external. Internal sources could include network event logs and archives of past occurrence responses.

IoCs lists are the most prevalent kind of sensitive info. However, other data types, such as customer credentials, raw code from paste sites, and text from news sources or social media, can also be considered risk metrics.

3. Processing

After gathering the raw data, it must be converted into a format appropriate for analysis. This typically comprises tasks like entering data into spreadsheets, decrypting files, translating details from foreign authorities, and assessing the data's accuracy and relevancy.

4. Analysis

Following the processing of the dataset, the team must conduct an in-depth analysis to address the questions presented in the prerequisites stage. In addition, the team strives to translate the dataset into deliverables and valuable recommendations for the stakeholders throughout the investigation step.

5. Dissemination

The open source threat intelligence team must then report the findings of their inquiry to the relevant parties during the distribution stage. It's important to evaluate your audience when crafting your research presentation. The endorsements should typically be provided in a brief report or set of slides, no more than one page.

6. Feedback

It is essential to obtain feedback on the report that was delivered in order to perfect the operation of CTI in the future. It is feasible for stakeholders' priorities, desired frequency of intelligence report delivery, the preferred method of data dissemination and presentation, and the preferred method of data dissemination and presentation to all shifts.

What is A CTI Feed?

Constant streams of useful information about potential dangers and criminals can be gleaned from various CTI feeds and sources. Analysts in the field of CTI assemble information on IoCs like unusual behavior and malicious domains, and IP addresses from a wide range of sources. While feeds provide a wealth of information about potential dangers, an analyst is required to go through it all to get the valuable data needed to write reports.

Threat Intelligence Tools

These products are sold or free through the open-source community. They all collect CIT differently:

• Malware disassemblers: tools that reverse-engineer malware in order to assist security engineers in protecting against attacks of a similar nature.
• SIEM: Security teams can use SIEM technologies to monitor the network in real-time for unusual activity and suspicious traffic. SIEM stands for security information and event management.
• Network traffic analysis tools: These gadgets collect and record events happening on the internet to assist in the detection of intrusions.
• Threat intelligence communities: Communities for the exchange of threat intelligence can supply CTI. These communities take the form of free websites that compile known IOCs and threat figures supplied by the community. Several of these networks provide information on threat avoidance and mitigation, as well as support for the coordinated study that is being promoted.

Associations are skillfully prepared to contradict attacks when their administrators are cognizant of the possibilities of dangers they might face. Every establishment needs to have a privacy plan that includes the use of threat intelligence tools.
