What is XDR? (Extended Detection and Response (XDR)

The subsequent phase in the advancement of endpoint detection and response (EDR) is referred to as Extended Detection and Response (XDR). XDR utilizes a holistic methodology for identifying and addressing potential threats, which optimizes the processes of data intake, analysis, preemptive measures, and remediation throughout an organization’s whole security infrastructure. The utilization of XDR’s unified interface enables security teams to efficiently detect concealed and intricate threats. This comprehensive platform facilitates the visualization and prompt response to threat data while also automating intricate and multi-faceted activities inside their security infrastructure. The two predominant subtypes of XDR are Open XDR and native XDR.

XDR functions:

Employ state-of-the-art automation and artificial intelligence (AI) technology to collect, correlate, and evaluate data from endpoints, cloud workloads, networks, and email.
The primary objective is to allocate precedence to data and provide security teams with valuable insights in a consistent manner through a unified console.
The objective is to integrate several security technologies into a unified console, thereby streamlining the processes of security analysis, investigation, and remediation.
When an individual acquires a managed solution, it may include the provision of proficient experts in the fields of danger hunting, threat intelligence, and analytics.

Due to the aforementioned characteristics, the use of XDR yields substantial enhancements in threat detection capabilities, expedites security operations, reduces total cost of ownership (TCO), and alleviates the persistent burden on security personnel.

What is SIEM?

Security information and event management (SIEM)

Security information and event management (SIEM) is a comprehensive framework comprising a range of tools and services designed to facilitate the analysis, understanding, and preparation for potential threats by security analysts. This framework integrates the functionalities of security events management (SEM) and security information management (SIM) to enable efficient retrieval and reporting of log data.

SIEM functions:

The process involves collecting log data from various sources within the organization and utilizing it to identify, categorize, and analyze incidents and occurrences.
By comprehensively collecting data from many components within an ecosystem, encompassing both the software and hardware aspects of a network, one can attain a comprehensive understanding of detrimental actions taking place.
Consolidate all factual information onto one, central platform.
The utilization of data is employed to generate warnings, provide reports, and improve incident response.

SIEM enables organizations to do real-time data evaluation from various network devices and apps. This capability can assist organizations in proactively identifying potential security vulnerabilities prior to their disruption of routine business activities.

What is SOAR?

Security orchestration, automation and response (SOAR)

The development of a suite of software tools known as Security Orchestration, Automation, and Response (SOAR) has been undertaken with the aim of enhancing an organization’s cyber security stance. A team of security analysts has the capability to oversee security data from various sources, including security information and management systems as well as threat intelligence platforms, by utilizing a Security Orchestration, Automation, and Response (SOAR) platform.

SOAR functionalities:

Minimize the necessity for human involvement through the collection of threat intelligence, implementation of automated solutions for straightforward responses, and prioritization of intricate dangers.
In order to enhance and optimize the security posture, it is recommended to integrate three software solutions, namely threat and vulnerability management, security incident response, and security operations automation.
The application of machine learning (ML) technology, in conjunction with manual and human intervention, is employed to evaluate incoming security data and establish the order of importance for incident response actions.

The primary goals of a Security Orchestration, Automation, and Response (SOAR) platform encompass the collection of threat-related information and the implementation of automated measures to counteract these threats. The utilization of a SOAR platform has the potential to enhance the efficiency and responsiveness of security teams.

What are the key differences between SIEM, SOAR and XDR?

SIEM

The primary purpose of Security Information and Event Management (SIEM) is to collect logs to facilitate compliance, store data, and conduct analysis. The effectiveness of risk identification is limited in security analytics without the implementation of a distinct security analytic function in conjunction with a substantial data collection. Currently, security analytics is primarily integrated into SIEM solutions as an additional feature rather than being developed as an independent capacity.

SOAR

As previously said, the integration of Security Information and Event Management (SIEM) with SOAR facilitates the coordination of orchestration, automation, and response functionalities. This integration enables diverse security technologies to establish effective communication channels among themselves. Nevertheless, the SOAR framework commences and concludes with a form of communication that occurs in both directions. Although the SOAR system is undeniably valuable, it does not comprehensively tackle the challenges posed by big data analytics or offer sufficient safeguards for data and system security.

XDR

XDR has emerged as a distinct approach to address the void created by SIEM and SOAR, employing a novel technique centered around endpoint data analysis and optimization. The organization is able to prioritize and promptly address incidents of utmost importance due to the advanced analytical capabilities of XDR.

FAQs

About SIEM, SOAR and XDR

1: What is the relationship between SIEM and SOAR?

In numerous instances, the combination of Security Orchestration, Automation, and Response (SOAR) and Security Information and Event Management (SIEM) is employed. The two platforms exhibit a complementary nature and possess the capability to collaborate synergistically in order to enhance the effectiveness of your security operations. This collaboration may be achieved through a two-step approach.

In the realm of cyber security, the primary purpose of a Security Information and Event Management (SIEM) software solution is to collect and disseminate alerts to be subsequently examined by security experts.

The sole purpose of a SIEM software solution, within the context of cyber security, is to collect and send alerts to security personnel to investigate.
The SOAR tool uses data on security issues to automate the response. SOAR also uses artificial intelligence to predict and respond to similar future threats.

The cooperation between SIEM and SOAR might be conceptualized as analogous to the relationship between an assistant and a manager. The identification of logs that meet the criteria for triggering alerts is accomplished by the Security Information and Event Management (SIEM) solution, which collects and analyzes logs in order to establish correlations. The Security Orchestration, Automation, and Response (SOAR) platform is capable of extracting data from the Security Information and Event Management (SIEM) system, subsequently facilitating the initiation of resolution endeavors.

Essentially, Security Information and Event Management (SIEM) offers log analysis and archiving capabilities that are frequently absent in Security Orchestration, Automation, and Response (SOAR) solutions. Although the Security Information and Event Management (SIEM) system does not possess response capabilities, the Security Orchestration, Automation, and Response (SOAR) system does offer such functionalities. In order to effectively utilize the data and insights produced by a Security Information and Event Management (SIEM) system, security teams would typically be required to utilize multiple interfaces external to the SIEM platform.

2: Is XDR a substitute for SIEM and SOAR?

The prompt reply is negative. Although XDR offers enterprises enhanced security capabilities and improved security measures, it is not advisable nor feasible to entirely substitute SIEM or SOAR with XDR.

Due to the inclusion of other use cases, such as log management, compliance, non-threat related data analysis, and administration, within the SIEM framework, it is evident that XDR cannot serve as a direct substitute for SIEM. Despite the fact that an XDR may frequently serve threat-centric use cases and hence replace SIEM in that regard, the business will still require the SIEM to meet other criteria.

Regarding SOAR, this platform offers beneficial orchestration capabilities that aid the security team in resource allocation and work prioritization. The absence of these features in XDR solutions underscores the need to maintain the operating status of the SOAR system and establishing a connection with XDR.

3: Does my organization need all three tools: SIEM, SOAR and XDR?

However, it is possible that the reasons extend beyond mere security concerns. This post examines the diverse security characteristics of SIEM (Security Information and Event Management), SOAR (Security Orchestration, Automation, and Response), and XDR (Extended Detection and Response). It emphasizes the integration of these technologies to provide a comprehensive and dependable security solution while also addressing other use cases. Organizations face the potential of experiencing breaches and other security problems when they fail to prioritize any of these three essential competencies, which could also result in their inability to fulfill other business requirements.
