Picking the Right Database Tech for Cybersecurity Defense

 Graph and streaming databases are helping defenders deal with complex, real-time threat and cybersecurity data to find weak points before attackers.

Modern cybersecurity technologies produce massive quantities of data, which requires rethinking how to store and manage all the different types of information being generated. Many cybersecurity platforms are increasingly relying on one of two database technologies — graph or streaming databases — to efficiently represent and query databases of threat indicators, asset inventories, and other critical cybersecurity information.





Graph databases allow for the properties and relationships of various objects — whether threat groups, devices on the network, or software vulnerabilities — to be connected and searchable. Streaming database technology allows real-time threat data and status updates to be efficiently processed and stored. Both technologies help companies move beyond the lists used by defenders in the past to track everything and to do so in real time.

"All of us who work in this field have long lamented the difficulty of defending against cyber intruders, but there hasn't been a single moment of change, just a gradual increase in complexity over time," says Irene Michlin, staff engineer and application security lead at Neo4j, a graph-database provider. "We've reached that tipping point in difficulty, where data has become evermore interconnected with 'many-to-many' relationships."

The changing nature of data collection and use in cybersecurity has necessitated moving to other approaches to storing and processing data. Social networks of threat actors, connected assets in defenders' networks, and indicators of compromise are some types of data where the relationships among the elements of the dataset is extremely important.

Graph databases allow for the efficient representation and querying of relationships among data entities — critical in cybersecurity for detecting patterns such as fraud or network intrusions, says Weimo Liu, CEO of graph-engine maker PuppyGraph.

Large Language Models and Vector Databases for News Recommendations

Image
  Large Language Models   (LLMs) generated a global buzz in the machine learning community with recent releases of generative AI tools such as Chat-GPT, Bard, and others alike. One of the core ideas behind these solutions is to compute a numerical representation of unstructured data (such as texts and images) and find similarities between these representations. However, taking all of these concepts into a production environment has its own set of machine learning engineering challenges: How to generate these representations quickly? How to store them in a proper database? How to quickly compute similarities for production environments? In this article, I introduce two open-source solutions that aim to solve these questions: Sentence Transformers  [1] : an embedding generation technique based on textual information and; Qdrant : a vector database capable of storing embeddings and providing an easy interface to query them. These tools are applied to NPR [2], a News Portal R...

MIT Researchers Develop Generative AI Tool to Boost Database Searches

Image
  MIT researchers have developed a generative AI tool for databases that lets users analyze data and make predictions about future data or fill in missing information. GenSQL is an extension of the Structured Query Language (SQL)  programming language  that integrates probabilistic programming with traditional database searches. It lets users analyze existing data, make predictions about future data and fill in missing information by combining SQL with probabilistic models of tabular data. The generative AI-powered tool lets business users ask complex questions that combine actual data with probabilistic reasoning, providing them with more nuanced insights about a product or service. The tool is designed to let developers employ probabilistic modeling in databases without requiring prior expertise in probabilistic programming. “ With GenSQL, both typical users and experts can more easily and interactively query generative models to test their validity, both qualitatively ...

NIH autism database announcement raises concerns among researchers

Image
A new research initiative from the U.S. National Institutes of Health (NIH) seeks to gather and analyze multiple autism-related datasets to better understand the underlying causes of the condition. Letters of intent are due tomorrow, but the project’s atypical call for applications has autism scientists divided on whether or not to participate. The Autism Data Science Initiative provides $50 million for an anticipated 10 to 25 projects, according to the 27 May announcement. The funding opportunity uses an Other Transaction (OT) funding mechanism, which tends to be implemented when, among other reasons, a project is expected to evolve over time, more collaboration is required from the NIH or nontraditional research groups are involved, according to an NIH website. For a field that has recently seen budget cuts, some researchers are welcoming the opportunity for funding, says   Helen Tager-Flusberg , director of the Center for Autism Research Excellence at Bosto...
