Advanced analytics such as user behavior analytics (UBA), network flow insights, and artificial intelligence (AI) have now been added to security information and event management (SIEM) platforms to speed detection and integrate seamlessly with security orchestration, automation, and response (SOAR) platforms for incident response and remediation. SIEM may be supplemented with consultancy and managed services to assist with a threat management program, policy management, and security staff. Security teams may use IBM Security® QRadar® SIEM (Security Information and Event Management) to identify, prioritize, and respond to threats throughout the company. It automatically analyses and collects log and flow data from hundreds of devices, endpoints, and apps throughout your network as part of your zero-trust approach, giving single notifications to expedite incident investigation and response. QRadar SIEM is accessible on-premises and in the cloud.

IBM QRadar: Product Versions

The IBM QRadar SIEM is available as hardware, software, or virtual appliance solution. Event processors gather, store, and analyze event data, whereas event collectors capture and send data, according to the product architecture. Flow processors for collecting Layer 4 network flows, QFlow processors for performing deep packet inspection of Layer 7 application traffic, and centralized consoles for SIEM management by Security Operations Center (SOC) analysts are also included in the SIEM solution. Flow processors are similar to event processors, but they are used for network flows, and consoles are used by employees who use or manage the SIEM.

IBM QRadar SIEM: Enterprise Product Overview

Unlike other SIEM systems, QRadar employs machine learning, cybersecurity AI, and behavior analytics to automate numerous security analyst duties, including threat hunting, vulnerability scanning, risk analysis, alarms, incident response, and conducting forensics on a discovered offense. QRadar SIEM transforms collected event logs, network activity logs, and scans into security intelligence that can identify and prevent both security risks utilizing security AI from a large number of industry expert sources. QRadar can effectively read and correlate event logs from more vendors than any other solution on the market, allowing for rapid and easy deployment of pre-defined searches, alarms, and reports.

IBM QRadar® Benefits

Near-real-time visibility for threat identification and prioritization, as well as surveillance throughout the whole IT infrastructure. QRadar facilitates the detection of unauthorized application use, insider fraud, and advanced slow and low threats. It gathers information from a variety of sources, including security devices, operating systems, applications, databases; and identity, and access management software. It also captures network traffic data from switches and routers, including Layer 7 (application-layer) data. QRadar also collects data from identity and access management solutions, as well as infrastructure services like Dynamic Host Configuration Protocol (DHCP), and vulnerability data from network and application vulnerability scanners.

Reduces and prioritizes alerts, so that investigations can be focused on a manageable number of suspected instances. For threat detection, compliance reporting, and auditing, QRadar conducts rapid event normalization and correlation with other data. It condenses billions of events and flows into a small number of actionable offenses, which are prioritized based on their business affect. QRadar uses activity baselining and anomaly detection to detect changes in behavior related to applications, hosts, users, and network regions. It optionally employs IBM Security X-Force Threat Intelligence to detect activities linked to dubious IP addresses, such as those suspected of hosting malware.

Allows more effective threat management, while also creating detailed data access and user activity reports. QRadar keeps track of major occurrences and threats, linking to all supporting data and context for a more thorough inquiry. To aid research, it searches events and flow data in near real-time streaming mode or on a historical basis. Through Layer 7 network flow collection, it also allows for the inclusion of IBM Security QRadar QFlow and IBM Security QRadar VFlow Collector appliances for deep insight and visibility into applications (such as enterprise resource management), databases, collaborative solutions, and social media. QRadar performs federated searches across large, globally distributed systems to discover off-hours or anomalous use of an application or cloud-based service, as well as network activity patterns that are discordant with past usage trends.

Supports a simpler, faster installation and provides time-saving features and tools. For considerable time savings, QRadar automatically detects and classifies hosts and servers by monitoring network traffic and recording the applications, protocols, services, and ports they use. It comes with a centralized user interface that provides role-based access by function as well as a global view for near real-time analysis, issue management, and reporting. QRadar also aggregates network flow records that occur within a specific time period into a single entry to help save storage space and licenses.

Capabilities for ultimate reporting to assist with compliance management, detailed data access, and user activity reports are generated. To verify that data-privacy standards are followed, QRadar records all access to client data by login and IP address. It comes with an easy-to-use reporting engine that eliminates the need for an extensive database and report-writing expertise. It also ensures that regulatory demands and compliance reporting are met through openness, accountability, and measurability.

Implementations packages and plans

The QRadar SIEM provides a lot of expansion and scalability options. There are a variety of All-In-One appliances to choose from, ranging in size from small to massive deployment options. The Enterprise Edition is designed for big deployments with 100,000-1,200,000 network traffic flows per minute and 50,000-600,000 events per second. By obtaining a bigger license code, any QRadar appliance may be upgraded to accommodate higher volumes or converted into a dedicated purpose module device. An All-In-One appliance, for example, maybe configured as a dedicated console, log collector, data expansion node, processor, manager, and so on. Customers may also utilize or add a virtual machine (VM) with QRadar software to an installation that includes both appliances and VMs.

Package 1 of the QRadar Enterprise Edition, 5737-H81, includes:

  • 50,000 events every second (EPS)
  • Flows at a rate of 600,000 per minute (FPM)
  • Database for advanced asset management
  • Five licenses with high availability
  • Installs of software for data nodes and collectors are unlimited.

5737-H81 QRadar Enterprise Edition Package 2 contains the following items:

  • a million events per second (EPS)
  • a flow rate of 1,200,000 gallons per minute (FPM)
  • Four data storage connections renewals.
