In the blog post we are going to discuss how and which Security Orchestration Automation and Response (SOAR) platforms are really shaking things up in the world of cybersecurity incident management and overall state of your network security.
A SIEM platform solution isn’t just another core security infrastructure. It’s a real game-changer, especially for our analysts in Security Operations Center (SOC) teams, who have their hands full protecting networks from all sorts of sneaky threats (phishing or ransomware), false positives.
The right SIEM solution will not only help protect your organization from threats but also streamline your security operations and make your life a whole lot easier. So take your time, ask the following questions about an effective SIEM solution, and make a choice that best fits your unique needs.
- How well does SIEM solution integrate with existing infrastructure?
It’s essential to understand if the SIEM solution can integrate with your current network infrastructure, security controls, and log sources. If it can’t, you could face considerable hurdles in getting it up and running effectively.
- What is the SIEM solution’s real-time monitoring capability?
SIEM solutions are designed to provide real-time visibility into all network activities. Hence, you must know how well the solution can monitor in real-time, how granular the monitoring can be, and how it handles peak data flows.
- Does SIEM solution support automated response capabilities?
In an era of sophisticated cyber threats, a SIEM solution must do more than just detection. It needs to have automated response capabilities that can instantly react to identified threats.
- What are SIEM solution data storage and retention capabilities?
Ask about the system’s capacity to store and retain data. Understand the scalability in terms of storage, and make sure it aligns with your company’s data retention policies and any relevant regulations.
- How flexible and robust are the reporting and analytics features?
Good reporting and analytics capabilities are a must. You should be able to generate various reports to meet both operational needs and compliance requirements. The analytics should provide actionable insights and have the ability to spot patterns and trends.
- What kind of threat intelligence does SIEM solution offer?
The SIEM platform should provide updated and actionable threat intelligence. It should be able to leverage global threat intelligence to stay ahead of evolving threats.
- What is the total cost of ownership (TCO)?
Beyond just the upfront cost of the solution, consider other associated costs such as deployment, training, maintenance, and any necessary upgrades. Understanding the TCO helps to make a more informed financial decision.

What are the four core functions of a SIEM Platform?
A SIEM platform provides a robust and comprehensive tool for organizations to enhance their security posture. In order to understand more, let’s delve into the four core functions of a Security Information and Event Management (SIEM) platform:
The four core functions of a SIEM platform are:
- Data aggregation
- Real-time analysis of events
- Support for incident investigation and management
SIEM Function #1: Data aggregation
Data aggregation in SIEM platforms provides a holistic view of an organization’s security events by collecting, normalizing, and consolidating logs from various systems into a single, consistent format. This capability greatly enhances the organization’s ability to detect and respond to potential security incidents.
What is an example of data aggregation in SIEM platforms?
Let’s take a fictitious company, “TechCorp Inc,” as an example. TechCorp has a complex network infrastructure comprising a multitude of devices and applications – firewalls, routers, servers running various operating systems, cloud services, proprietary applications, and more.
Each of these components produces its own logs in unique formats.
The firewall, for instance, may generate logs about traffic details, including source and destination IPs, port numbers, protocols, and whether the traffic was allowed or blocked.
On the other hand, a Windows server may produce logs about user login attempts, system errors, or application activities. Similarly, a cloud service might generate logs related to API calls, user activities, or resource usage. Each of these logs is formatted differently based on the design of the specific system generating them. The SIEM platform comes into play by collecting all these diverse logs. It uses agents or collectors which can be installed on or connected to these various devices and applications.
These agents are responsible for gathering the logs and forwarding them to the SIEM system. Once the logs arrive at the SIEM system, they undergo a process called normalization.
During normalization, the SIEM transforms all the different log formats into a unified format, ensuring consistency across all data. For instance, it might map the ‘source IP’ field from the firewall logs, ‘User IP’ from the cloud service logs, and ‘Client IP’ from the Windows server logs to a standard field, say ‘Source_IP’, in the SIEM’s unified format.
This normalized data is then indexed and stored in a way that makes it easily searchable and analyzable. Now, when TechCorp needs to investigate a security event, they can look at this normalized data from their entire infrastructure in one place, in one consistent format, irrespective of the source of the logs. This unified view simplifies the task of identifying security threats and reduces the time to respond to incidents.
