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