What is SOAR | Definition and Meaning

What is SOAR?

SOAR stands for Security Orchestration, Automation, and Response. It refers to a set of tools and processes that help security teams manage security events and incidents more efficiently. By integrating various security technologies and automating workflows, SOAR empowers organizations to respond to threats quickly and effectively.

The Basics of SOAR

SOAR platforms are designed to streamline a variety of cybersecurity operations. They facilitate coordination between different security tools and data sources, thereby enhancing an organization�s ability to detect, investigate, and respond to incidents. Particularly as cyber threats become more complex, the need for effective incident response mechanisms remains paramount.

How Does SOAR Work?

SOAR operates through a combination of automation and orchestration. Automation refers to the automatic execution of tasks without human intervention, while orchestration is the coordination of different systems and processes to work in harmony. Together, these functions enable SOC (Security Operations Center) teams to process security alerts efficiently.

Key Capabilities of SOAR Tools

• Incident Response: With automated incident response capabilities, SOAR tools can mitigate threats as soon as they are identified. This reduces the time window during which a threat might cause damage.

• Playbooks: SOAR tools utilize predefined playbooks to standardize responses to various types of incidents. Playbooks outline the necessary steps to take based on specific scenarios, ensuring consistency and thoroughness in response efforts.

• Integration with Other Security Solutions: SOAR platforms can integrate with various security technologies, including SIEM (Security Information and Event Management) systems. This wide-ranging integration helps create a more comprehensive security posture.

SOAR in Cybersecurity: Examples and Tools

There are numerous SOAR tools available on the market today, each offering unique features and advantages. Some of the top examples of SOAR tools include:

• Splunk SOAR: Formerly known as Phantom, Splunk SOAR is a robust platform that combines automation and orchestration to enhance the efficiency of security teams. It offers features like incident response playbooks and real-time alerting.

• Swimlane: Swimlane provides a flexible SOAR solution with a focus on reducing mean time to respond (MTTR), allowing organizations to fine-tune their incident response strategies.

• Demisto: Now a part of Palo Alto Networks, Demisto combines automation and collaboration for incident management, enabling faster detection and response to threats.

Benefits of SOAR

Implementing a SOAR solution has several benefits for organizations:

1. Increased Efficiency: Automation allows security teams to focus on higher-level decision-making rather than repetitive tasks.

2. Faster Response Times: With automated incident response capabilities, organizations can substantially reduce the time it takes to respond to threats.

3. Improved Visibility: A centralized platform provides security teams with a comprehensive view of their security posture.

4. Cost Savings: By streamlining operations and reducing the need for extensive manual intervention, SOAR can help lower operational costs.

The Relationship Between SOAR and SIEM

Understanding the difference between SIEM and SOAR is crucial for organizations navigating the cybersecurity landscape. While SIEM solutions focus primarily on collecting and analyzing log data in real time, SOAR platforms build on that foundation by automating responses and orchestrating actions across multiple security tools.

SOAR vs. SIEM

• Focus: SIEM�s primary role is to centralize data and enhance visibility, whereas SOAR automates responses based on that data.

• Functionality: SIEMs might alert security teams to potential threats, while SOAR can initiate a response without human intervention.

Known Vulnerabilities Related to SOAR

In the past, several vulnerabilities have been identified in various SOAR platforms, putting organizations at risk of potential attacks. Notable examples include:

1. CVE-2023-38019: The IBM SOAR QRadar Plugin App versions 1.0 to 5.0.3 exhibited a vulnerability that allowed remote attackers to traverse directories on the system. This vulnerability could be exploited by sending specially crafted URL requests containing “dot dot” sequences, enabling the viewing of arbitrary files on the system.

2. CVE-2023-38020: In the same versions of the IBM SOAR QRadar Plugin App, authenticated users could manipulate output written to log files, presenting a risk of information exposure or system abuse.

3. CVE-2023-38263: Similar vulnerabilities were found in the IBM SOAR QRadar Plugin, where improper access controls allowed authenticated users to perform unauthorized actions, compromising system integrity.

4. CVE-2021-20527: The IBM Resilient SOAR v38.0 had vulnerabilities that would allow a privileged user to create malicious scripts executable as another user, risking the security of the entire system.

5. CVE-2021-20566: Poor cryptographic practices in IBM Resilient SOAR v38.0 allowed attackers to potentially decrypt highly sensitive information, increasing the likelihood of data breaches.

6. CVE-2021-20567: A vulnerability in IBM Resilient SOAR v38.0 enabled a local privileged attacker to obtain sensitive information due to inadequate encryption measures.

7. CVE-2021-22854: SQL injection vulnerabilities existed in the HR portal of the SOAR cloud system, allowing remote attackers to access all data in the database without the necessary privileges.

8. CVE-2020-4633: IBM Resilient SOAR v38.0 had a vulnerability that permitted remote attackers to execute arbitrary code on the system due to formula injection resulting from improper input validation.

These vulnerabilities exemplified the importance of continuous vigilance, regular updates, and adherence to security best practices within SOAR platforms to mitigate risks associated with cyber threats.

SOAR is a vital component of modern cybersecurity strategies. As cyber threats continue to evolve, the integration of security orchestration, automation, and response capabilities provides organizations with the tools they need to effectively manage security incidents.

Whether through enhancing operational efficiency, providing incident response playbooks, or streamlining tasks through automation, SOAR tools play an essential role in maintaining robust cybersecurity defenses. Understanding and leveraging these capabilities is paramount for organizations looking to stay ahead in an increasingly complex and threatening digital landscape.

For further exploration into SOAR solutions, many tools are available on the market, each offering unique features to suit various organizational needs. Popular SOAR tools such as Splunk SOAR and Swimlane serve as popular resources for security teams aiming to improve their incident response and overall cybersecurity posture.
