AI-Driven Cyber Security Risk Scoring and Prioritization

Semantic Search MITRE ATT&CK

When we think about the security of our systems, a lot of it can be compared to a game of chess. Imagine, for a moment, if the chessboard is our entire digital infrastructure—network, identity, cloud, and SaaS. The myriad of pieces on the board? They’re the numerous components that make up that infrastructure. Every move an opponent (attacker) makes represents a step closer to a potential compromise.

Now, consider this: what if, instead of manually plotting our defense strategy piece by piece, move by move, we had a formidable assistant on our side? An AI that not only understood the game but could predict potential moves, leveraging an understanding of more than 90% of attacker tactics, techniques, and procedures (TTPs) as cataloged by the MITRE ATT&CK framework.

The future of security isn’t just about recognizing threats—it’s about understanding them.

Enter the age of AI-driven security prioritization and risk scoring. Using the semantic search of MITRE ATT&CK techniques alongside network, system, and application logs, we’ve now positioned ourselves with an almost prescient capability to analyze attacker behavior post-compromise. This isn’t about merely reacting; it’s about proactively recalibrating our defense mechanisms.

Semantic search involves understanding the intent and contextual meaning of words and phrases in a query rather than just returning results based on exact matches or keyword density. When applied to the realm of cybersecurity and, more specifically, to the MITRE ATT&CK framework, semantic search can drastically enhance our ability to sift through, analyze, and leverage the vast troves of information related to attacker tactics, techniques, and procedures (TTPs).

Here’s how semantic search could be applied to MITRE ATT&CK techniques:

  1. Query Expansion: When a security analyst searches for a particular TTP or threat actor, semantic search could automatically expand the query to include related terms, synonyms, or even other TTPs that are commonly associated with the initial search term.
  2. Contextual Understanding: Instead of merely searching for exact matches, a semantic search engine could return results based on the broader context of a search term. For example, if an analyst searches for “credential dumping”, the engine might return results related to techniques attackers use to harvest credentials, tools commonly used for this purpose, or preventive measures an organization can adopt.
  3. Intuitive Correlations: Semantic search can connect seemingly unrelated TTPs based on shared attributes, tools, or known threat actors. This aids in comprehensively understanding a threat landscape and even predicting potential attack chains.
  4. Temporal Analysis: By understanding the semantic meaning of TTPs, a search engine could map out the evolution of specific techniques over time, offering insights into how certain threats have morphed or how threat actors have shifted their strategies.
  5. Improved Threat Intelligence: Armed with semantic search, threat intelligence platforms can provide more relevant and contextual information to security teams, ensuring that they’re not just bombarded with data but are receiving meaningful insights.
  6. Enhanced Red and Blue Team Exercises: Red teams (offensive security teams) can use semantic search to find novel ways of simulating attacks, while blue teams (defensive security teams) can utilize it to understand the semantic links between different stages of an attack, helping them to better detect and respond.
  7. Training and Education: For those new to the MITRE ATT&CK framework or cybersecurity in general, semantic search can provide a more intuitive way to understand and delve into the intricacies of various TTPs. It can also guide users towards related content that can enhance their learning experience.
  8. Integration with Other Data Sources: Semantic search can be used to cross-reference MITRE ATT&CK techniques with other datasets, such as vulnerability databases, to provide a holistic view of potential threats associated with specific vulnerabilities or even software products.

In essence, integrating semantic search with MITRE ATT&CK techniques can supercharge the way we understand, analyze, and act upon cyber threats. By moving beyond keyword-based searches and diving deep into the meaning and relationships between various TTPs, organizations can achieve a richer and more proactive security posture.

In the end, this isn’t merely about outsmarting attackers; it’s about reimagining what’s possible in the realm of digital defense. As with most things, when we stop trying to merely keep up and instead focus on leaping ahead, the future becomes not just a place to defend but a space to innovate.
