What is SIEM?

Security Information and Event Management (SIEM) is a cybersecurity software that combines Security Information Management (SIM) and Security Event Management (SEM) methods. Generally, a SIM analyses log and event data in real-time. In turn, it provides threat monitoring, event correlation, and incident response by Threat Modelling. However, SEM collects, analyses, and reports on log data from various sources across the network to improve log management.

Why do you need to use a SIEM? SIEM tool advantage.  

  1. Updates and centralizes the organizations’ cybersecurity scenery in an only platform.
  2. Discovers irregular user behavior patterns that could indicate threats from hackers or internal security risks. In turn, the recent SIEM launches a quick response.
  3. Uses HIDS to monitor the network 24/7 and identifies any suspicious activities through network traffic analysis.
  4. Detects and prevents security breaches and possible cyber threats.
  5. When a SIEM tool detects any security incident sends real-time alerts.
  6. Avoids data breaches early by identifying threat indicators.
  7. Helps organizations with IT regulations compliance.
  8. Allows forensic analysis and speeds up post-incident recovery.

What are the most crucial SIEM features?

Each SIEM tool prioritizes certain features and functionalities. That’s why you must understand SIEM basics to choose the tool that meets your needs. Whether you decide to go for a free, paid, or open-source SIEM program, you should always look out for the following features.

Unlimited log collection

As we well know, modern SIEM solutions collect data from every available source and process it for correlation and analysis. Generally, the most common data sources are the cloud, networks, logs, and more. However, your SIEM must hold up data management from a single point of control.

Visualization

Visualization is a crucial feature to consider when organizations are looking for a SIEM. Usually, the modern SIEM tools deliver extensive dashboard management that allows visualizing the data through graphs, charts, and other graphics. Therefore, ensure to acquire a SIEM that makes it easier to understand the data to analyze.

Threat intelligence

When a SIEM includes threat intelligence, the product is more competent. The threat intelligence allows providing more information about IP addresses, domains, websites, or logical entities currently associated with malicious behavior. Also, it would be better if the SIEM supports using any threat intelligence feeds instead of a particular feed.

Compliance reporting

The compliance reports help identify and report system configuration deviations or unauthorized access to data. Besides, it is used for assessing the risk/impact of violations or detecting potential violations. Therefore, the SIEM to chose must include built-in reports depending on your compliance needs and ability. Also, it should allow creating new reports or built-in tailor reports according to your organization’s requirements and characteristics.

Forensics capabilities

An advanced SIEM can capture additional information about security events to identify attacks, gather evidence, and investigate incidents. The cyber forensic investigation allows discovering who infringed security protocols and policies to take disciplinary or prosecution measures.

Compatibility

The SIEM should have compatibility with different types of devices to monitor all the data in an organization. They also need to be compatible with other security products such as endpoint protection to avoid a vulnerability from any direction.

SIEM tool disadvantages

  1. Usually, SIEM is expensive to implement and maintain.
  2. Difficult to install and manage, but with the proper support become easy.
  3. Collects too much data, and they could be challenging to process for any IT department.
  4. Needs constant updating.
  5. The SIEM tool requires attentive staff to operations with continuous tuning.
