Advantages of SIEM includes:
1. Faster detection of threats
2. Better use of security resources
3. Improved incident management
4. Improved compliance with regulations
Let us discuss each of these in detail:
Advantages of SIEM
1. Faster Detection of Threats
SIEM helps with the faster detection of threats and security incidents. Perhaps you can send SIEM security alerts to various people in incident management. (e.g., administrators, security analysts, etc.). The SIEM can also correlate the alerts from different sources. For example, firewall logs, antivirus logs, etc. That is, to identify the threat and potential risk faster.
In addition, SIEM-generated security alerts can have central management. This allows you to set up alert rules to manage the alerts based on your organization’s policies.
For example, you can: have a policy where alerts must be in review by a Senior Analyst before being escalated to the Security Operations Center (SOC). Or maybe you only want high-priority alerts to go to the SOC and others to go to the administrator’s inbox.
The SIEM can perform a deeper analysis of alerts and provide more details. This analysis is usually by an included correlation engine or external correlation tools (e.g., HP ArcSight, IBM QRadar, Splunk, etc.). By performing this deeper analysis, the SIEM can help with the faster detection of threats and security incidents.
2. Better Use of Security Resources
SIEM security alerts can be sent to various people involved in incident management (e.g., administrators, security analysts, etc.). The SIEM can also correlate the alerts from different sources (e.g., firewall logs, antivirus logs, etc.) to identify the threat and potential risk faster.
Moreover, SIEM security alerts are managed centrally so they are easy to manage and use by all team members involved in incident management (e.g., administrators, security analysts, etc.).
A centralized SIEM console allows all these people to see what is happening on their network or system in real-time without having to log in to each device or system separately or use multiple consoles or tools for each one of them individually.
Plus they don’t have to read through hundreds of pages of log data or search thousands of events looking for indicators of compromise (IOC). They just need to look at a single console with multiple views that shows all the important information they need in one place at one time.

3. Improved Incident Management
SIEM-generated security alerts can be managed centrally so they are easy to manage and use by all team members involved in incident management (e.g., administrators, security analysts, etc.).
Also, SIEM gives you a single place to store all security alerts and manage them. This includes all log data, rules, and alerts from multiple sources. You get a consolidated view of all your security incidents, making it easier to investigate them. Plus it is easier for other team members (e.g., administrators, security analysts) to access the SIEM console to see the latest alerts and monitor their network or systems in real-time. This allows them to respond faster and take action immediately.
4. Improved Compliance with Regulations
Also, SIEM gives you a single place to store all security alerts and manage them. This includes all log data, rules, and alerts from multiple sources. You get a consolidated view of all your security incidents, making it easier to investigate them. Plus it is easier for other team members (e.g., administrators, security analysts) to access the SIEM console to see the latest alerts and monitor their network or systems in real-time. This allows them to respond faster and take action immediately.
Many organizations have compliance requirements that they must meet (e.g., PCI DSS). A centralized SIEM console allows all these people to see what is happening on their network or system in real-time without having to log in to each device or system separately or use multiple consoles or tools for each one of them individually.
