Elasticsearch use cases in cybersecurity

Elastic Stack at its core relies on Elasticsearch, Kibana and a variety of data ingestion tools. Elasticsearch with its capabilities for indexing and retrieving of textual data, and Kibana for analytics and visualization of data stored in Elasticsearch indices. Furthermore, Kibana is very intuitive, making it very easy to perform advanced data analysis and visualize of data in a variety of charts, tables, and maps.

In the context of cybersecurity, and thanks to Elasticsearch performance and extensibility, analysts can apply it to protect their organizations. Some example of those applications are:

Elastic Security

The Elastic stack has a dedicated solution for cybersecurity purposes that combines analytical capabilities (like threat detection) and protection capabilities (like endpoint prevention and response) into one offering. On a high level, Elastic Security offers following benefits and capabilities:

Elastic Security stack architecture

The above diagram depicts the overall architecture of Elastic Security and its different components.

Data is ingested into Elasticsearch from different sources:

A Detection engine is used to continuously search for signs of attacks (e.g. suspicious host and network activity). It relies on a set of Detection rules to periodically search the data for suspicious events and generate alerts when such events are discovered. Users can provide their own rules or use the ones packages with Elastic Security. Furthermore, it provides a Machine learning base a anomaly detection components that analyses host and network data for potential attacks and provide a score for further investigation by an analyst.

In the rest of this article we will focus on the Vulnerability management use case of cybersecuirty and discuss how Elastic stack can be leveraged for this specific type of applications.

Vulnerability management

As depicted in the following diagram, Vulnerability management can be defined as the process of identifying, analyzing, and addressing weaknesses and vulnerabilities present in software products, networks, or systems. It involves continuous discovery, tracking, reporting, and mitigation of known vulnerabilities to prevent potential threats from being exploited. Thus making it an important practice for any organization as it helps maintaining a secure environment, meeting regulatory compliance obligations, and reducing risks from cybersecurity threats.

Elasticsearch offers numerous benefits when applied to vulnerability management processes, providing both automation and scalability to address the increasing volume and complexity of incoming vulnerabilities. Here are some specific use cases where Elasticsearch might play a vital role in vulnerability management:

That’s all folks

We went through a veriety of cybersecurity related use cases for Elasticsearch and then focused on the vulnerability management use case. In a next article, we will implement a vulnerability tracking system based on Elasticsearch. Stay tuned!
