Next-Generation SIEM and Advanced Capabilities
Next-generation SIEMs are designed to go beyond the capabilities of traditional SIEM platforms. They offer advanced features and functionalities tailored to address the evolving threat landscape.
These advanced capabilities make next-gen SIEMs a powerful tool for organizations looking to enhance their cybersecurity defenses.
One of the vital advanced capabilities of next-generation SIEM is User and Entity Behavior Analytics (UEBA). This feature leverages AI and machine learning algorithms to analyze patterns of human behavior within an organization’s network.
By monitoring user activities, UEBA can detect insider threats, targeted attacks, and fraudulent behavior that could go unnoticed by traditional SIEM systems.
“User and Entity Behavior Analytics provides organizations with valuable insights into the behavior of internal users, enabling them to identify potential security risks and take proactive measures to mitigate them.”
Another advanced capability of next-gen SIEM is Security Orchestration and Automation Response (SOAR). SOAR enables organizations to automate their incident response procedures and investigations.
With SOAR, security teams can streamline their workflows, reducing response times and enhancing their overall efficiency in addressing security incidents.
Next-generation SIEMs also excel in complex threat identification and detection. They can identify and respond to threats without relying on predefined rules or signatures.
This ensures that organizations can avoid emerging threats that may not yet have established patterns or signatures.
Next-gen SIEMs also offer powerful capabilities in analyzing lateral movement within an organization’s network.
By tracking and analyzing the movements of threats across different systems and entities, these SIEMs can provide valuable insights into the extent of a security breach and the potential impact on the organization.
Furthermore, next-generation SIEMs excel in entity behavior analysis. This involves analyzing the behavior of network entities such as applications, servers, and IoT devices.
By detecting abnormal behaviors and deviations from baseline patterns, next-gen SIEMs can identify potential security risks and take timely action to prevent attacks.
Advanced Capabilities of Next-Generation SIEM:
- User and Entity Behavior Analytics (UEBA)
- Security Orchestration and Automation Response (SOAR)
- Complex Threat Identification and Detection
- Analysis of Lateral Movement
- Entity Behavior Analysis
| Capability | Description |

SIEM Deployment Models and Considerations
Organizations can choose from different deployment models that best suit their needs when implementing a Security Information and Event Management (SIEM) system.
These models include self-hosted, cloud, and SIEM as a service. Each deployment model has its considerations and benefits, and understanding them can help organizations make informed decisions.
Self-Hosted SIEM
In a self-hosted SIEM model, organizations deploy and manage the SIEM infrastructure on-premises within their own data center. This deployment model provides complete control over the system and allows organizations to customize it according to their specific requirements.
With self-hosted SIEM, organizations can integrate the SIEM system seamlessly with existing security tools, networks, and processes.
However, self-hosted SIEM requires an organization to have dedicated resources to effectively manage and maintain the system, including hardware, software, and personnel with SIEM expertise.
It also involves upfront costs for infrastructure setup, software licenses, and ongoing maintenance and upgrades.
Cloud SIEM
Cloud SIEM, on the other hand, involves hosting the SIEM system in the cloud. This model offers several advantages, including reduced infrastructure costs, scalability, and flexibility.
Organizations can leverage the cloud provider’s infrastructure and resources, eliminating the need for on-premises hardware and maintenance.
Cloud SIEM also allows for easy scalability, as organizations can adjust resources based on their evolving needs.
Additionally, cloud SIEM providers often offer additional built-in features such as threat intelligence feeds and machine learning capabilities, enhancing the overall security posture.
SIEM as a Service
If an organization prefers to focus on its core business without the complexities of managing an SIEM system, SIEM as a Service is a viable option.
With SIEM as a Service, a managed security service provider (MSSP) takes care of all aspects of the SIEM system, from event collection and aggregation to correlation, analysis, and reporting.
This model allows organizations to leverage the expertise and experience of the MSSP’s security analysts and engineers, providing 24/7 monitoring and response capabilities.
SIEM as a Service also offers predictable costs, as organizations pay a subscription fee based on their needs without upfront investment in infrastructure and personnel.
Considerations for SIEM Deployment
When choosing a SIEM deployment model, organizations should consider several factors:
- Existing Infrastructure: Evaluate the organization’s IT infrastructure to assess compatibility with the chosen deployment model. Consider integration requirements and potential disruptions during implementation.
- Data Location: Determine whether the organization is comfortable moving its data off-premises in the case of cloud SIEM or SIEM as a service.
- Expertise: Assess the availability of security staff with SIEM expertise within the organization for self-hosted or hybrid-managed models. For SIEM as a Service, consider the need for joint management with an MSSP.
Overall, the choice of SIEM deployment model depends on various factors, such as organizational resources, budget, scalability needs, and security requirements.
By carefully considering these factors, organizations can select the most suitable deployment model that aligns with their goals and maximizes the effectiveness of their SIEM implementation.
| Deployment Model | Benefits |
|---|---|
| Self-Hosted SIEM |
|
| Cloud SIEM |
|
| SIEM as a Service |
