What Is Security Information and Event Management (SIEM)? Definition, Architecture, Operational Process, and Best Practices

Information and Event Management (SIEM) is a security system that helps increase security awareness and recognize security risks and threats. It collects data from various security devices, analyzes and monitors the data, and then presents the results in a format that is useful to the company that is using it. This article describes SIEM in greater detail and shares some of the most effective practices for 2022.

What Is Security Information and Event Management (SIEM)?

Information and Event Management (SIEM) is an effective security tool that can help increase security awareness and recognize security risks and threats. It gathers data from various security devices, then analyzes the information and displays results in a way appropriate to the company using it.

Security Information and Event Management (SIEM)

SIEM is a blend of information security management (SIM) and security event management (SEM). It warns businesses about possible threats, incidents involving information security, and compliance concerns.

The SIEM’s primary function is to provide various monitoring, logging, collection and administration of security data for audit or compliance purposes, as well as operational capabilities like reports, data aggregation security monitoring, and activity monitoring.

What is SIEM function?

Companies can use SIEM software to track, audit, and reconnect with all of the logs their systems produce, regardless of whether they are devices, applications or personal computers. It will notify them of security problems before the occurrence of any security issues instead of relying upon a reactive intervention.

SIEM software is a tool to collect data produced by various networks, applications, and security systems like hosts, networks, firewalls, and antivirus events, to mention just a few. It then brings all this data together in a central area.

For instance, if SIEM detects a security threat, it creates an alert and alerts and reports the threat to the right individuals. SIEM’s customized dashboards will also reduce the time needed to investigate false positives.

What is the significance of SIEM crucial?

It’s an understatement to state that the amount of hackers has been steadily increasing in recent years, causing damage to companies across the globe as well as infringing on their privacy and leaving them defenseless. Security software for event and information management is essential for every security-conscious company.

A well-designed SIEM system will respond quickly to an abnormal event. It does not just monitor actions in a network environment but also analyzes the events that trigger alerts for users and performs automated efforts to identify and address cybersecurity threats and weaknesses before they cause havoc.

SIEM software captures the logs and events generated by various software, security devices, and host frameworks and then combines the data into a single platform. SIEM applications provide:

  • Unified alerts.
  • Advanced full-packet logging capabilities.
  • The intelligent correlation can enhance security operations.

Understanding the Architecture of Security Information and Event Management (SIEM)

SIEM typically refers to the detection of threats, prevention, and management. The purpose of the SIEM solution is to offer an immediate awareness of current events, and it helps an organization identify and respond to threats quickly.

Its structure plays a vital part in keeping SIEM functioning smoothly. When SIEM is set up, proper attention must be given to its configuration and technical aspects.

Let’s learn about the essential elements of SIEM. Let’s look at the core components of SIEM design and obtain valuable insight into this platform’s functions.

Log management

SIEM gathers information intelligently to provide various helpful information, including the performance of employees, financial health, patterns of clients, and many more. It is the component responsible for collecting data, managing it, and investigating the previous retention of data. As illustrated in the image earlier, SIEM collects both event data and context information, such as information from devices, installed services, storage protocols, network protocols, and stream protocols.

The log normalization image above clarifies that SIEM receives event and context data as input where normalization is crucial. The most important thing to remember is that turning events into security information can be accomplished by simply filtering out unneeded or irrelevant information from the collected information. This is because the primary goal is to remove irrelevant and redundant data and to keep only relevant information for further analysis.

Logs’ sources

To better understand how logs are integrated into the SIEM Company, it is essential to examine the procedure of collecting, mixing, and analyzing internal records. Logs can be retrieved from different systems, like security and networking systems and cloud-based systems. This component primarily focuses on the data sources and the locations where it’s transferred.

Reporting and hosting of SIEM

Various models are available for hosting SIEM, including self-host, cloud host, and hybrid host. SIEM detects and reports suspicious or suspicious actions based on the logs available.

Monitoring in real-time

Data breaches are among the most significant concerns for companies nowadays. SIEM offers real-time monitoring that helps not only detect malicious attacks but also determines their source, predicts the threat, and takes the appropriate steps to avoid any data leaks.
