QRadar and Splunk features and options

IBM QRadar SIEMLeverage automation to discover security log sources and new network traffic generated by other assets appearing on the network. It also uses advanced association rule engines and behavior analysis techniques to reduce millions or billions of data points into a manageable list of required studies. The solution comes with more than 400 support modules and dozens more are available on the IBM Security App Exchange.

“By associating multiple security events with known patterns of malicious behavior, QRadar can identify cyber breaches, data breaches and anomalies in an organization's network,” said Patric Vandenberg, director of security programs at IBM.electronic security planet"This core capability is strongly supported by vulnerability management, network forensics tools, and an integrated incident response solution right on the bench."

Splunk Enterprise Security (EN)It provides a clear visual image of the posture, with the ability to customize the view and zoom in on raw events as needed. Ongoing safety monitoring and case management andincident responseThe capabilities allow users to rapidly conduct investigations to detect threats using ad-hoc search and static, dynamic, and visual correlation.

The Splunkbase App Store provides access to over 600 apps that work with Splunk security solutions, including Splunk Security Essentials fordata hijacking, Splunk Security Essentials for fraud detection, the Cisco Networks app for Splunk, and the Splunk app for PCI compliance. The Splunk Adaptive Response Initiative, a security collective of more than 30 partners, also helps integrate technologies likenext generation firewall,Security end postInthreat intelligence.

Recent SIEM Product Enhancements

Last year, IBM enhanced QRadar with the addition of IBM QRadar with Watson, which combines the power of Watson with the QRadar security analytics platform; IBM QRadar User Behavior Analytics, which analyzes user behavior to detect malicious activity; and IBM QRadar Network Insights, a real-time analysis of network data to detect attacks and security threats. IBM QRadar Cloud Security has also been enhanced to protect cloud services from AWS, Azure and O365.

New additions to Splunk products over the past year include Splunk ES Content Updates, a subscription service that provides prepackaged security content to help customers detect, investigate, and manage specific threats, and Booz Allen Hamilton Cyber4Sight for Splunk, which provides clients with access to actionable security intelligence from Booz Allen's Threat Intelligence Service. The company has also releasedSplunk User Behavior Analysis (UBA) 4.0, allowing customers to create and upload their own machine learning models to identify custom threats and anomalies.

Strengths and Weaknesses: IBM

QRadar is ideal for medium to large enterprises that require basic SIEM capabilities,knuthand those looking for a unified platform that can manage a wide variety of security monitoring and operational technologies.

Still, there are some drawbacks. While IBM offers a BigFix solution for endpoint monitoring, Gartner says its clients have shown little interest and are turning to third-party solutions. The company also reported that QRadar's UBA capabilities lagged behind other vendors and that the IBM Resilient incident response tool did not offer native integration with the QRadar platform.

Gartner claims better-than-average incident management and response capabilities and workflow, but full orchestration and automation can only be achieved through IBM's advanced Resilient Incident Response Platform solution. Threat hunting is also very important with i2 Analyst's Notebook from IBM.

Pros y contras: Splunk

Splunk offers a comprehensive solution that allows users to customize the solution over time and provides advanced analytics across the platform. Integration services are provided by a wide range of partners and apps are available through the Splunkbase app store.

However, Gartner reports that some of its clients are concerned about the licensing model and overall implementation costs. Splunk has introduced new licensing options to address these issues. Since Splunk does not offer an appliance version of the solution, companies that require on-premises appliances must turn to third-party providers.

Gartner says that Splunk focuses primarily on basic SIEM capabilities and does not have specific advanced threat detection solutions. Splunk Stream (included with Splunk Enterprise) can collect network traffic for analysis, while Splunk Universal Forwarder can be used as a lightweight proxy for endpoint analysis, the company said.

SIEM User Considerations

Users of both SIEM products have their own opinion.

Colt Rogers, an infrastructure engineer at IT services company Zirous,wroteSplunk has been "very helpful in proactively monitoring client hardware, network, and security activities."

Zirous uses Splunk, among other things, to proactively lock accounts based on machine learning of the average number of failed login attempts for the average person. This is useful when a network breach is contained almost immediately thanks to an automatic logoff policy.

A Director of Engineering and Security Operationsthe lawIBM QRadar can correlate global business data, third-party solution integrations, and machine learning capabilities like Watson integrations and near real-time indicators of compromise. He pointed out that the incident was detected in real time.

QRadar is available as on-premises hardware or software or in the cloud. Smaller clients can offload all implementation and maintenance to IBM's cloud-based solution, while larger enterprises can choose to go on-premises or take a hybrid approach to collect data from on-premises and application-based applications. cloud, Vandenberg said.

Splunk ES can be deployed as on-premises software in public or private clouds or in hybrid deployments through the Splunk Cloud SaaS solution. "Many of Splunk's customers are becoming more interested in using Splunk ES in the cloud," said Girish Bhat, Splunk's director of product marketing.electronic security planetvia email. "Today, many customers are shifting their overall security model from an on-premises model to a hybrid model that allows them to perform security analytics both on-premises and in the cloud."

pricing structure

IBM QRadar pricing is based on events per second (EPS) and traffic per second (FPS). On-premises solutions start at $10,400 including 12 months of support, while cloud-based solutions start at $800/month/year. IBM QRadar Community Edition is a low memory, low EPS version of QRadar that is available for free.

Splunk pricing is based on the number of users and the amount of data ingested per day. The free version is available for a single user with a maximum of 500 MB of data per day. Splunk Light, for up to 5 users with up to 20 GB of data per day, starts at $75 per month billed annually. Splunk Enterprise, for unlimited users and up to unlimited data per day, starts at $150 per month for 1 GB of data per day, with discounts per GB as data grows: $83 per GB for 10 GB of data per day USD For example , 100 GB of data per month costs USD 50 per GB per month.

With machine data growing 50 times faster than traditional enterprise data, Splunk has seen customer data ingestion rise significantly to double-digit terabytes, Bhat said. “It also means absorbing more data sources, giving security analysts a more complete picture of your security posture,” he said.
