The cybersecurity sector is abuzz with all kinds of jargon and abbreviations and you may have come across the acronyms SIEM and SOAR. They stand for Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) and these systems safeguard organizations against cyber threats and attacks. Integral components of any cybersecurity defense strategy, SIEM and SOAR perform distinct functions yet both work best when they are integrated and synergized to identify potential threats and respond to any incident.
What is SIEM?
SIEM, or security information and event management is a technology that analyses security alerts from applications and network hardware in real time. The process it follows entails collecting, aggregating, analysing as well as storing log data in large volumes across the enterprise. Based on this analysis, SIEM identifies any patterns or anomalies that might point toward a security issue.
SIEM tools are indispensable to any cybersecurity plan as they provide a comprehensive perspective of an organization’s IT security by gathering data from several sources such as applications, systems, and network devices. With this unified system, SIEM tools can efficiently perceive any security threat and respond to it.
What is SOAR?
SOAR, or security orchestration, automation, and response is a technology that provides an integrated security solution by combining data collection, threat management, incident response, and security automation. This technology aims to streamline threat response workflows leading to improved efficiency of security operations.
SOAR is ideal for organizations that require efficient management of a large volume of alerts. These automated solutions perceive and gather threat intelligence from different sources and utilize this data to respond to alerts. With this mechanism, the response time to threat perception and management is reduced drastically. SOAR also automates repetitive tasks that give security analysts the time and bandwidth to focus on strategic functions like advanced incident response.
Differences between SIEM and SOAR
SIEM and SOAR are unique in their way and come with capabilities that make them a significant part of any robust cybersecurity strategy. While SIEM’s advanced capabilities are important for real-time analysis of security events to identify threats, SOAR’s automation of routine tasks enhances incident response processes by allowing security teams to prioritize critical tasks. Their roles are complementary and to truly understand how they work, let’s first look at their differences:
- Primary Function
The most important difference between SIEM and SOAR is their role or function in a cybersecurity regime. By collecting and analysing log data from multiple sources, SIEM identifies potential threats and performs the role of a security alarm that alerts the security team about any suspicious activity. On the other hand, the primary function of SOAR is to prioritize alerts based on threat levels, automate responses, and streamline security operations.
- Threat Management Technique
SIEM technologies work by correlating data and analysing it further to identify any potential threats. They detect inconsistencies and issues by leveraging advanced algorithms and generate alerts to flag any unusual patterns. In the case of SOAR, an automated response is generated to combat a threat based on predefined workflows and this process is known as a triggered outcome. SOAR technologies are effective in automatically responding to threats by blocking malicious IP addresses and isolating infected systems.
- Efficiency and Scalability
SIEM systems come with the capability to handle and process large amounts of data from multiple sources. They are known for their scalability and can match the needs of a large and diverse organization. By providing rich data, they assist security teams in crucial tasks such as incident investigation and threat hunting. Even as SOAR platforms are capable of handling multiple alerts, their scalability is not at par with SIEM as they are not equipped to process data from numerous sources.
- Ease of Implementation
When it comes to implementation, SIEM systems can pose some challenges. Organizations should be willing to invest a significant amount of time and resources establish and implement them. They also need to be constantly updated and fine-tuned to ensure their effectiveness. In contrast, a SOAR solution operates automatically and is less complex as it ingests data from limited sources. Nevertheless, it has to be integrated with existing security systems and must be continuously managed to ensure effectiveness.
Integrating SIEM and SOAR
As cyber threats become more menacing, organizations need to create a foolproof security system that includes efficient tools such as SIEM and SOAR. Many organizations rely on SIEM to get a holistic picture of their IT landscape. They can augment the efficiency of SIEM by integrating it with SOAR and creating automation capabilities to instantly respond to a security incident with little or no human assistance. Furthermore, SOAR solutions are adept at streamlining incident response and creating overall efficiency of security operations. By harnessing the power of SIEM and SOAR, you can create a proactive system that identifies threats and responds to them instantly. The combination of these two powerful technologies can result in a holistic defense strategy that allows organizations to protect their digital assets against possible threats.
