What are SIEM and SOC?
Security information and event management (SIEM) is the process of real-time analysis of security alerts generated by applications and network hardware, which is done by incorporating SIM and SEM under one framework. The machine-generated data is collected and monitored for security assessment.
SOC or the Security Operations Center is a facility that houses a team of security experts that monitors the organization’s security and safeguards it. The SOC includes various sectors like SIEM, GRC, VAPT tools, IDS, and IPS. SIEM is an integral part of the Security Operation Center (SOC).
We will discuss two SIEM products here: Splunk and IBM QRadar.
Key Factors of Comparison
Splunk: Splunk was founded in 2003, becoming the world’s first, in the words of Splunk founders- “A Data-to-everything Platform,” designed to bridge the gap between data and security by introducing the intelligent data monitoring system.
QRadar: Qradar was developed by Q1 Labs and acquired by IBM in 2011. IBM announced that the acquisition would help its clients more intelligently secure their organization by applying analytics to connect information from major security domains and forming security dashboards for their organizations.
Gartner is a prominent research and advisory company which has clients in 77% of the worlds’ top 500 companies of all size. They release their research on the various domain of information security and Information technology on an annual basis, and we’re considering one such annual summary. The image under discussion is the Gartner’s Magic Quadrant for the year 2020 under the category of SIEM (Security Information and Event Management).
The quadrant is divided into four sections:
Gartner investigates various SIEM products on the basis of key attributes of comparison and importance and summarizes their report in the form of Magic Quadrant and Critical Capabilities.
Some of the attributes that Gartner evaluates the products are:
Below are the attributes used in QRadar v/s Splunk for this year.
3. Deployment & Target Industry
Splunk: Splunk is primarily developed to be deployed as a software on-premise as a SaaS solution on Splunk cloud. It can also be deployed on public or private cloud and even Hybrid cloud (a combination of private and public cloud)
Splunk is essentially used for industries that are heavily regulated. E.g., Oil and Gas, Financial services, healthcare, Banks, Airline and Railways, nuclear plants, space research organizations, etc.
QRadar: QRadar is available as on-premises hardware or software or in the cloud. Smaller customers can offload all the deployment and maintenance to an IBM cloud-based solution, while larger firms can choose either an on-premises deployment or adopt a hybrid approach collecting data from local and cloud-based applications
QRadar is used in enterprises and moderately regulated industries. E.g., Private IT corporations, small to large companies.
4. Fundamental Comparison (Pricing, metrics, and Intelligence)
We’ve seen that QRadar is used in Medium to Large organizations, and Splunk is deployed in small-scale enterprises. We’ll see some detailed analysis of both these products based on:
We’ll discuss these components for Splunk and QRadar:
5. Pros and cons of Splunk
After going over the basic comparison between the two, here are some insightful findings:
6. Pros and Cons of IBM QRadar
MacAfee ESM and AlienVault USM are major competitors of QRadar apart from Splunk.
