What is Security Incident and Event Management (SIEM)?
Introduction
Security Incident and Event Management (SIEM) is a system that monitors all security-related events on an enterprise’s network. SIEM collects, normalizes, and analyzes data generated by security devices such as routers, switches, or firewalls. It then generates logs that are forwarded to the SIEM platform for consolidation, analysis, and reporting purposes.

Security Incident and Event Management (SIEM) helps organizations detect cyber threats, manage information assurance, comply with regulatory requirements, ensure continuity of operations planning, protect intellectual property, maintain business reputation, and more. Security Incident and Event Management (SIEM) is often managed by a central console or software application that can be accessed remotely to monitor the entire IT infrastructure of the organization.
What is Security Incident and Event Management (SIEM)?
Security incident and event management (SIEM) is a system that can help in the detection, analysis, damage assessment, diagnosis, correlation, and response. SIEM is usually deployed to ensure the availability of information systems. By implementing this strategy in your organization, you are able to assess risks more efficiently. There are several components that are included in the process of deploying a proper security incident and event management system. These include technologies for risk assessment, policy management tools for prevention of attacks on critical assets, application monitoring for rapid identification of potential security breaches, etc.
SIEM has been most commonly deployed in organizations that have regulatory requirements or have higher risks associated with their particular business environment. For example, the banking industry has higher risks than regular industries. Therefore, to maintain compliance with the industry requirement, the banking sector commonly deploys SIEM systems.
How to use SIEM?
SIEM is a cutting-edge technology that tracks and monitors logs to find out if there was any suspicious activity. This type of software can be used by organizations and individuals. Organizations and individuals usually install the software on a computer or device to help them monitor their IT infrastructure, security events, and system logs.
SIEM will aid in collecting data from devices and systems attached to an individual’s network, including physical components like switches and routers, as well as virtual ones such as CPU utilization sensors. Then this data is analyzed by the SIEM, to help in identifying foreign threats. SIEM will log all suspicious activity to make it easy for administrators to track down security breaches when they occur.
How many types of SIEM are there?
There are three types of Security Incident and Event Management (SIEM) Systems: “Open Source SIEM”, “Commercial SIEM” and “In-house Software”.
An open-source SIEM is software that makes use of free software components. It’s typically used to gather logs and metrics, analyze them for security events and send notifications about them to users. It can be installed on-premises or in the cloud by the user.
A commercial SIEM is software that builds upon open source SIEM, often with additional components that are proprietary. It’s typically used to gather logs and metrics, analyze them for security events and send notifications about them to users. It can be installed on-premises or in the cloud by the user.
In-house software is software that builds upon open source SIEMs or commercial SIEMs, often with additional components that are proprietary. It’s typically used to gather logs and metrics, analyze them for security events and send notifications about them to users. It can be installed on-premises or in the cloud by the user.
What are the benefits of using SIEM?
The benefits of using SIEM are that it is able to reduce the complexities of cyber security, provide a holistic view of the business, and collaborate. SIEM is able to provide a single place to consolidate all security information, which decreases complexities by not having multiple sources of data. Thus, SIEM allows for organizations to have an up-to-date overview of their cyber security. Secondly, SIEM provides a holistic view of the business where it can demonstrate the strength and weaknesses in different areas of the business. Finally, SIEM’s collaboration capabilities allow for effective communication and improved cyber security culture. Organizations will understand what to improve and how they should monitor their cyber security.
What are the drawbacks of using SIEM?
One of the drawbacks is that companies can be overwhelmed by the vast amounts of data that come into their system. This sometimes leads to the company being unable to have a single view of what’s occurring. Another drawback is that it might lead to alert fatigue in which case when there are alerts, they are ignored, or sometimes when there are no alerts, they are still checked. One more drawback is the technical dependency because the information is hosted in a proprietary format. If anything happens to the system, it might be impossible to retrieve data from that SIEM. Another drawback is that users will have to be more aware of security risks and threats because they cannot rely on a tool to provide all the necessary information for them. Another drawback is that budget might be a problem. SIEM requires a lot of storage and processing in order to have all its features active. It can become expensive quite quickly which can cause companies not to be able to follow up with the constant updates that SIEM needs.
Conclusion
Security Incident and Event Management (SIEM) is a new enterprise-grade application for the security industry. Its purpose is to collect, aggregate, analyze, manage and report on all of an organization’s log events in one place. The goal of this process is to detect potential cyberattacks or insider threats before they happen. SIEM can also be used as an early warning system that alerts administrators about possible problems with their network infrastructure prior to any major damage being done. There are many benefits associated with using Security Incident and Event Management but there are some drawbacks too. In order to discover the root cause of a cyberattack, SIEM provides an organization’s security team with the ability to detect and track anomalies in real-time. This way they can take quick action following a cyber security incident or threat, thereby minimizing damage and liability. By aggregating all of an organization’s events into a single database, SIEM also helps to prevent a significant amount of security data from being lost or overlooked.
