IBM QRadar Tutorial


Usually, most companies would discover the cybersecurity breach long after the damage has already been done. In the months following the incident, the executives and other personnel would dedicate their time and resources to investigate and respond to the events that led to the attack. Then, the situation would be tackled with the help of costly post-incident damage control. Post analysis would involve a painful discovery process that would identify the vulnerabilities that had allowed the attack. In this IBM QRadar Tutorial, you will learn all the basics of IBM QRadar. First, let’s see What is the IBM QRadar? Further, you will come to know what made IBM QRadar come into play.

What is the IBM QRadar?

The IBM QRadar is a security information and event management or SIEM product that is designed for enterprises. The tool collects data from the organization and the network devices. It also connects to the operating systems, host assets, applications, vulnerabilities, user activities, and behaviors. IBM QRadar is used to perform analysis of the log data and the network flows in real-time so that malicious activities can be identified and stopped as soon as possible. Thus, the main aim of the IBM QRadar is to prevent or minimize the damage to its host organization.

The following are some of the reasons that lead to the most common problems faced by organizations in terms of security:

  • Lack of actionable real-time security intelligence indicators
  • Minimal endpoint visibility
  • No security or poor AI integration
  • No detection of anomalous or abnormal activity
  • Too many tools and poor integration
  • The volume of logs that produce noise
  • Automation with poor or no defense
  • Higher cost for maintaining and managing security
  • Lack of resources and proper skills
  • An inability to enforce the compliance policies efficiently

The IBM QRadar SIEM uses a real-time integrated Cybersecurity AI, machine learning, and behavior analytics to prevent the attacks in the blink of an eye and with a very less cost compared to what human supervision can ensure. QRadar can address the bulk security issues that the companies face and save a lot of money. The security teams that struggle with patching endpoints properly and updating them can get their problems solved with IBM BigFix that has QRadar SIEM integrated into it. Most of the common issues are solved with this.

Deployment of the IBM QRadar SIEM is possible in the form of software, hardware, or a product meant for virtual application. Event processors for the collection, storage, and analysis of event collectors and event data make up the architecture of the product. They help to capture and forward the data.

There are flow processors as well that collect the network flows of Layer 4 of the OSI model. The Layer 7 application traffic gets a deep packet inspection through the QFlow processors. Management of SIEM can be performed by the SOC or Security Operations Center through centralized consoles. The flow processors are similar to the event processors, however, these are meant for network flows. The consoles offer a lot of help to the people who are managing or using the SIEM.

Evolution of IBM QRadar

According to IBM, the QRadar Security Information and Event Management is an essential tool that would aid the security teams in prioritizing the threats across the enterprise and detecting them accurately. The tool offers the necessary intelligent insights that would help the teams to respond as quickly as possible and reduce the impact of the incidents. Network flow data and log events from thousands of endpoints, devices, and applications over the network are consolidated.

QRadar then correlates all the different information and these related events are compiled to produce single alerts so that remediation and incident analysis can be accelerated. QRadar and SIEM are available in on-premises and cloud environments.

What does QRadar SIEM Mean?

IBM Security Operations QRadar is an enterprise security information and event management (SIEM) product that can be integrated easily for supervising security workflows. The two workflows that are included in the base system include - Run Enrichment for IP and Security Incident Enrichment.

If the Source IP, Configuration Item or Destination IP are modified in a security incident, The REST calls to the second workflow are caused by a business rule. A call would be made for each of the modified fields. Following this, the Security Incident Enrichment workflow would make calls to QRadar depending on the modified fields. QRadar then sends the enriched data to the security incident and populate the work notes with a summary of the event flows and offenses related to the IP addresses. The data can be viewed on the QRadar console through the links included in the summary.

Role of QRadar in Event Management

IBM Security QRadar demonstrates a modular architecture where deployments of various sizes and topologies are supported. All the software components run on a single appliance in a single-host deployment. The QRadar console provides the user interface and real-time events, reports, asset information, offenses, and administrative functions.

Event management requires the supervision of several things like data nodes, the QRadar components, system health, network interface, network, and off-site hosts. Managing an event also requires the maintenance of different objects, which is done as specified underneath.

  • Viewing the system health information - The system notifications and health information are shown in the system health view for the host.
  • Data nodes - A data node is an appliance that can add to the event and the flow processors to improve the search performance or increase the storage capacity. An unlimited number of data nodes can be added to the IBM Security QRadar deployment and they can be added at any time. Each data node can be connected to a single processor but a processor would be able to support multiple data nodes.
  • QRadar component types - Each appliance that is added to the deployment would have configurable components that would specify the way the host functions under the surveillance of QRadar.
  • QRadar system time - When the deployment is across multiple zones, all the appliances would use the same time as the IBM Security Radar Console. The alternative is to use Greenwich Mean Time.
  • Network interface management - Extra network interfaces can be added in addition to the default management interface to the IBM QRadar appliances. This would offer alternative network connectivity.
  • NAT-enabled networks - The function of the network address translation or NAT is to translate an IP address in one network to a different one in another network. Increased security is provided for the IBM Security QRadar deployment as the requests would be managed through the translation process. The internal IP addresses would be hidden.
  • Deploying changes - The configuration settings can be updated from the Admin tab. The changes would be saved to a staging area where these are stored until manual deployment.
  • Management of the off-site hosts - The off-site hosts are those that cannot be accessed through the QRadar Console in the current deployment. An off-site host can be configured to transfer the data for reception from the QRadar deployment.
  • Shutting down the systems - The appliance would be powered off as soon as the system is shut down. The IBM Security QRadar interface would become unavailable and the data collection would stop.
  • Collection of log files - The log files contain detailed information like hostnames, email addresses, and IP addresses. The log files can be collected and sent to IBM Support for further assistance.
  • Resetting SIM - Additional false positive information can be avoided by resetting the SIM after tuning the deployment. All source and destination IP addresses or offenses can be removed from the SIM through this step.

QRadar Architecture Overview

The modular architecture of IBM QRadar can be used for prioritization and threat detection. The QRadar can be scaled to meet the flow and log collection. Integrated modules can be added to the QRadar platform like QRadar Vulnerability Manager, QRadar Risk Manager, and QRadar Incident Forensics. The operation consists of three layers and would apply to any QRadar deployment structure, and it is true regardless of the size and complexity.

Data Collection

The first layer is data collection where data like flows or events are collected from the network. Direction collection through the All-in-One appliance is possible. Collectors like QRadar QFlow Collectors or QRadar Event Collectors can be used for the collection of event data. The data gets parsed and normalized, and then passed to the processing layer. The parsed data is normalized to present in a usable and structured format.

The QRadar SIEM’s core functionality is based on a collection of data and flow. Event data represents those events that occur at a point in time in the environment like firewall denies VPN connections, user logins, emails, proxy connections, and other events that should be logged.

The flow data, on the other hand, represents network activity information between two hosts. QRadar translates them into flow records. QRadar would normalize and translate the data to IP addresses, packet counts, ports, and other information in the flow records. It represents a session between two hosts. Full packet capture is available with the QRadar Incident Forensics in addition to collecting flow information with a Flow Collector.

Data Processing

In the second layer, event and flow data are run through the Customs Rules Engine or CRE. This generates alerts and offenses which are written to storage. There are features like QRadar Vulnerability Manager, QRadar Risk Manager, and ORadar Incident Forensics to offer more functionality.

Data Searches

The data collected and processed by QRadar is available to the users for searches, reporting, analysis, and alerts of offense investigation. The users can search and manage the security admin tasks on the QRadar Console.

How does SIEM work?

IBM Security QRadar takes the log data from the log sources that are used by the applications and devices in the network and consolidates them. However, it is important to take note that the software versions for all the IBM Security QRadar appliances in a deployment must be having not only the exact versions but the same fix level.

What are the major/primary SIEM tools?

The various tools under IBM QRadar help in data processing. The major ones are as follows.

  • QRadar Vulnerability Manager - The tool scans the process and network vulnerability data. This data is used to identify the security risks in the network.
  • QRadar Risk Manager - QRadar Risk Manager collects the network infrastructure configuration and provides a map of the network topology. The data can be used to manage risk by the simulation of network scenarios by implementing rules and altering the configurations in the network.
  • Radar Incident Forensics - This tool performs in-depth network forensics and replays full network sessions.

Benefits to using IBM QRadar SIEM

IBM QRadar SIEM is one of the best products when it comes to security management for an organization. The benefits of using this product are stated below.

Complete visibility for the cloud and traditional environments

It is true that getting insight across multiple security environments can be tough. However, with IBM QRadar, you would gain centralized insight into the network events and data flow, be it an IAAS or SaaS environment

Elimination of manual tasks empowers the analysts

The analysts lose valuable time trying to manually track the processes. Thus analysts are often pulled from their work at hand. The product offers a solution that allows the users to see all the events related to a particular threat in a single place and eliminate the manual tasks so that analysts can focus on response and investigation.

Real-time threat detection

It is difficult to keep out an eye constantly for threats as it would be a good wastage of time and resources. The out-of-the-box analytics would investigate into the network flows and logs detecting threats and prioritizing general alerts and force the attacks into the kill chain.

Security capabilities

In addition to the basic SIEM capabilities, support is offered for the threat intelligence feeds. The license extension would have the IBM Security X-Force Threat Intelligence that would identify the URLs and IP addresses that are associated with malicious activity. A threat score and category would be given to each identified IP address or URL, which would help the organization prioritize threats and offer better analysis.

Reporting capabilities

IBM QRadar offers proper support for the major compliance reporting requirements initiatives like Payment Card Industry Data Security Standard, North American Electric Reliability Corporation, Health Insurance Portability, and Accountability Act, Federal Energy Regulatory Commission, and Gramm-Leach-Bliley Act. The product offers a report builder wizard for security teams to create custom reports.
