As the volume of information processed and transferred between different information systems increases, organizations and individual users increasingly depend on the continuity and accuracy of these processes. Responding to security threats requires tools that can analyze the growing number of events in real time. One solution to this problem is the use of a SIEM system. The main principle of SIEM systems is to collect data about the security of information systems from various sources and present the results of their processing in a single interface for use by security analysts. It helps to learn the most important features related to security; managed SIEM combines Security Information Management (SIM) and Security Event Management (SEM) into a single security management system.
Information security management system
SIM UnderDefense is primarily responsible for analyzing events in your infrastructure, improving the long-term performance of your system, and optimizing the storage of data collected in logs. A SIEM security incident management system, on the other hand, emphasizes extracting a certain amount of information from existing data to immediately identify security events. The functionality of this system is constantly expanding and improving with the growing need for additional functions.
What is SIEM used for?
One of the main goals of using a SIEM system is to increase the level of information security in existing architectures by intervening in security information and performing preventive management of security incidents and events in real time. Proactive security incident management means making decisions before the situation becomes critical. This type of control can be implemented using automated mechanisms for predicting future events based on historical data and automatically adapting event monitoring parameters to specific system conditions. SIEM UnderDefense is represented by applications, hardware, and services and is used to generate reports for data logging and interoperability with other business data.
Important benefits of using a SIEM system
Spend your time on productivity instead of maintaining, servicing, and maintaining SIEM tools. Automate time-consuming and repetitive tasks so your team can focus on areas where their expertise can be effective. Early and rapid threat detection takes seconds. UnderDefense’s SIEM platform provides a maximum response to threats. Detect, automate and collaborate on investigations faster, and remove threats faster. Create environmental transparency. Eliminate fraud zones in the enterprise, from the endpoint to the network and the cloud. Easily search logs and other intelligence data to find the answers you need and understand what’s happening in your cyber environment. Use the system today and smoothly scale it tomorrow. The complexity and scale of your environment will grow rapidly. Don’t settle for basic solutions that quickly become outdated. Higher productivity and lower operating costs today and tomorrow.
The principle of action
SIEM is used to monitor and analyze incoming information, but SIEM does not protect your infrastructure from external and internal threats. Collected analyzes are used to detect cyber incidents and optimize business protection. Criteria for assessing the state of the infrastructure are established. The devices monitored by the SIEM are displayed. When an event occurs that exceeds the configured model, the SIEM responds to the change and logs the event. It is important to first implement the system on a small number of devices for testing purposes. An administrator checks its health, edits its rules, and then runs it in operational mode. Additional functions of the system: Based on the received data, the behavior of the attacker is analyzed. In other words, the event log is useful for research.
Built-in notification notifies administrators of violations or issues via email, SMS, and instant messaging. This software is a flexible tool that can be customized according to the needs and wishes of the user.
The software solution is traditionally divided into two components. The first is a monitoring agent. They are embedded in the elements of the information system in which reading takes place. The second element is the server part. Process information from the agent and log incidents and events according to specific rules. Information processing and event logging templates are set by UnderDefense information security specialists during setup. A modern SIEM solution is a cross-functional platform that combines software, hardware, and management services to analyze each system’s security log entries, detect abnormal user-level behavior, and generate alerts. The benefits of a SIEM system for IT departments are the ability to analyze reports of security breaches in real-time, review the requirements of security policies and regulations, detect attacks promptly, and respond quickly to incidents.
UnderDefense’s Information Security Division is also responsible for the detailed analysis of recorded events. Create reports, respond to incidents, and use built-in tools to prevent future incidents. Intermediate elements such as adders and correlators are also integrated. The first is set as normal memory. Filter the data to remove duplicates and empty records. Second, the data you need is isolated from many events. As information comes in different formats and types, SIEM systems collect information and present it in a single view. SIEM technology provides real-time analysis of security events (alerts) from devices and network applications, enabling action to be taken before serious damage occurs. As the volume of information processed and transferred between different information systems increases, organizations and individual users increasingly depend on the continuity and accuracy of these processes. Responding to security threats requires an ever-increasing number of tools capable of analyzing events in real time. The principle of SIEM systems is the collection of security data from IT systems from various sources, and the results of their processing are presented in a single interface for use by security analysts. This helps to explore the most important functions that respond to incidents related to and directly related to cyber security. Functionality is constantly expanded and supplemented as the demand for additional functions grows. One of the main goals of using SIEM systems is to increase the level of information security in existing business environments by providing additional functionality for security management and proactive management of security incidents/events. Security incident management consists of decision-making using automated mechanisms to predict future events and automatically adjust event monitoring parameters to specific system conditions.
