The ever-growing Cyber Security Threat Landscape is becoming a challenge to Organizations to detect and respond quickly to threats and minimize the effect of security incidents. “Cyber-attacks can get costly if not resolved quickly” Source: Ponemon Institute 2017 Cost of Cyber Crime Study: United States study”.

Implementing SIEM and SOAR technologies will equip the organization with strong monitoring, detection, and response capabilities to reduce the time and cost of security incidents.

What is SIEM?

SIEM stands for Security Information and Event Management is the technology that collects, analyze and store security events and logs from different sources such as firewalls, intrusion detection systems, network appliances, operating systems, applications, etc.

How SIEM solutions can help an Organization improve its Security Posture?

Centralized Log Management – Endpoints, servers, network devices, and security devices generate a huge amount of logs that are impossible to be manually reviewed regardless of how many resources you hire and hence there is a need for a tool to centrally store, aggregate, and correlate these logs to make it easier for security analysts to review and take actions based on it.

Threat Analysis – SIEM provides the ability to detect risky scenarios and common attack patterns, as well as attack paths defined by the organization itself

Improved Visibility– Individual security controls such as IDS, endpoints security, asset management solutions, etc. has limited visibility on what is happening inside the network. Having SIEM will provide the security team with a comprehensive view across different network parts.

Compliance – SIEM helps organizations to comply with local, international standards and regulations by generating reports about different network components from a centralized unified interface.

Forensic Support – SIEM allows forensic analysts to search within logs of many systems in a centralized way, without the need of re-collecting the log files of compromised systems.

What is SOAR?

SOAR stands for Security Orchestration, Automation, and Response, terminology adopted by Gartner, is an approach to security operations and incident response used today to improve the security operations’ efficiency, efficacy, and consistency.

SOAR helps security teams manage and respond to a huge number of alarms quickly. SOAR takes things a step further by accumulating comprehensive data gathering, case management, standardization, workflow, and analytics to provide organizations the ability to implement sophisticated defense-in-depth capabilities.

The benefit of the SOAR technology includes but not limited to, reducing the time from breach discovery to resolution, minimizing the risk resulting from security incidents, improving the effectiveness and efficiency of SOC operations while increasing the return on investment for existing security technologies.

SOAR technology is addressing the challenges of Alert Overload, Disparate Tools, Manual Processes, and Talent Shortage.

“by year-end 2022, 30% of organizations with a security team larger than five people will leverage SOAR tools in their security operations, up from less than 5% today.”

SIEM and SOAR Solutions Together

SIEM and SOAR are recommended to work together to provide a collective defense against cyber threats and attacks. Traditionally, SIEM raises alerts to notify security administrators of malicious activity and security administrators manually work on the incident response activities which is usually time-consuming even for minor and repeated tasks that can be automated. SOAR takes incident response capabilities to new heights by facilitating automated responses for minor and repeated incidents that don’t require human intervention at machine speeds.

To summarize, SOAR along with SIEM will serve as a cybersecurity accelerator by responding to common cybersecurity incidents faster and smarter which will, in turn, save the precious time of the Cyber Security experts and allow them to work on critical tasks.
