A company's Security Operations Center (SOC) is planning to implement a new SIEM system. They are evaluating different deployment models. Which of the following best describes a 'hybrid' SIEM deployment model?

  1. AMultiple SIEM instances deployed across different geographical regions for redundancy.
  2. BA combination of on-premises log collectors and data processors with cloud-based analytics and storage.
  3. CAll SIEM components, including log storage and analytics, are hosted entirely in the cloud.
  4. DAll SIEM components are deployed on-premises within the company's own data center.
Show answer & explanation

Correct answer: B. A combination of on-premises log collectors and data processors with cloud-based analytics and storage.

A hybrid SIEM deployment combines elements of both on-premises and cloud-based solutions. This typically involves deploying log collectors and possibly some processing components on-premises to handle sensitive data locally, while leveraging the scalability and advanced analytics of a cloud platform for storage and deeper analysis.

Why the other options are wrong

  • A. This describes a distributed on-premises or cloud deployment, but not necessarily a hybrid model in terms of combining cloud and local infrastructure.
  • C. This describes a pure cloud-based SIEM deployment.
  • D. This describes a pure on-premises SIEM deployment.

Hybrid SIEM Deployment

A hybrid SIEM deployment model combines on-premises and cloud components, often utilizing on-premises log collectors and data processors for local data handling, with cloud-based analytics, storage, and scalability.

  • Blends on-prem and cloud SIEM.
  • Offers flexibility for data residency and scalability.
  • Common for organizations with mixed infrastructure.
