A Beginner’s Guide to SIEM(Security Information and Event Management)
Cyberattacks are a persistent threat to any organization’s IT infrastructure worldwide. Organizations constantly strengthen security laws and concentrate on minimizing their security vulnerabilities to maintain safety and keep way ahead of anticipated attackers. Regularly strengthening security is a complex and time-consuming task. Incorporating SIEM software into a security team’s toolset could be one practical step. But what exactly is SIEM, and how does it benefit security for teams?
What is SIEM?
A security information and event management (SIEM) solution is aimed to collect all information across your business, standardize it to make it accessible, analyze it for irregularities, and then monitor events and remediate issues to keep intruders out.
SIEM is an integral part of a security stack, your very own looking glass into the state and health of your infrastructure. SIEM solutions provide real-time analysis, monitoring, and alerting. By bringing in logs from your system’s different components, they create security information to analyze and act upon.

Why is SIEM important, and how does it work?
SIEM collects event information across an organization’s network. The log data is captured from the users, apps, resources, data centers, and networks. SIEM software generates warnings for an organization’s security personnel when it detects a risk, breach, threat, or unusual behavior.
SIEM plays a vital role in compliance as most standards like the PCI DSS, GDPR, and HIPAA require the collecting and reporting log data. The growing emphasis on compliance and keeping businesses secure has made SIEM solutions more valuable to small and medium enterprises.
Insider Threats pose a considerable risk to every organization. SIEM enables the managing and monitoring of user access and events. They quickly alert about irregularities identified by processing and analyzing log data. SIEM normalizes the data collected from various sources to provide easy-to-understand visualizations which provide crucial information about the health of your infrastructure. This provides the ability to investigate any irregularities in your environment.
Key Benefits of SIEM:
A perfectly deployed SIEM system can help boost a firm’s security infrastructure in a number of ways. Here are some of them:
- Enhanced Efficiency.
- A comprehensive evaluation of a business’s IT security.
- Real-time monitoring and continuous visibility for being compliant.
- Reduction in the time to detect and provide remediation assistance immediately.
- Visualizing raw log data can immediately identify threats, risks, and anomalies.
What to Look for in a SIEM Provider?
SIEM is a versatile tool, but at the same time, it requires technical expertise to deploy and integrate your infrastructure into the solution. After implementing the SIEM, security experts will need to analyze the information. Hence, one should always look for the Managed SIEM services as they take care of all the management with this tool. The managed service providers have a deep understanding of using the tool. You will not have to worry about the security as the managed provider will be responsible for that. But what all does a Managed SIEM provider offer?
Managed SIEM services offer cloud-based deployments, allowing organizations to outsource security expertise, rapidly reduce initial deployment costs, integrate infrastructure, and streamline their security operations. Managed SIEM has become an increasingly popular option for SMBs as it allows them to secure themselves without bearing the overhead of deploying and maintaining the SIEM solution.
