That security against cyberattacks is one of the most important aspects in a company is beyond doubt. In reality, the number of cyber attacks continues to increase day by day, since they are more and more powerful and dangerous.
That is why, preparing and protecting yourself from these threats is not enough, but with anticipating them. A) Yes, to prevent them and protect the IT security of companies, there are very useful tools such as SIEM systems.
A) Yes, in this post we show you what is a SIEM system, what is it for, how does it work, its benefits and some examples of tools of this type. Are you ready to know one of the most powerful tools at the cybersecurity level?
What is a SIEM system
An event management and security information system or SIEM (in English, Event management and security information) is a technology that can detect, quickly respond to and neutralize cyber threats.
SIEM technology is the result of combining the functions of two product categories: SEM (security event management) y SIM (security information management).
On one side, with SEM, storage is centralized and it is possible to analyze in near real time what is happening in security management, detect abnormal accessibility patterns and give more visibility to security systems.
Besides, with SIM, long-term data is collected in a central repository for further analysis and automated reports delivered to the IT security department.
Both functions allow very fast action against attacks, since on the one hand they provide greater visibility and on the other they make it possible to use the data to monitor and analyze security in real time, as well as warn of present and future threats.
How a security information and event management system works
On one side, the relevance of these solutions is that they prevent threats that are not associated with software vulnerabilities such as malware or denial of service (From).
Besides, a SIEM tool also guarantees the control of internal attacks. This is essential, since an antivirus, a firewall or other equivalent technology does not react in time to internal threats.
With the information obtained, reports are prepared that are later distributed to security personnel or IT management by email or through a web portal created for this purpose.. With the reports you can analyze an alert before the disaster.
In reality, information gathering is imperative for companies, since these systems can also improve research capabilities and, therefore, help meet compliance mandates.
5 benefits of SIEM technology for companies
Some of the advantages of security information and event management systems are as follows.
1. Threat detection
Since a SIEM relies on machine learning and cutting-edge technologies to identify both unknown threats and behavioral anomalies without the need for rules or signatures, no need to wait for the attack to occur, but the system itself. potentially malicious activity alerts.
2. More speed when investigating alerts
The context, visibility and threat intelligence give analysts more information on how to act. This speed comes from contextualizing and gathering threat intelligence related to the alert. At the same time, since SIEM incorporates automation, they also offer recommendations on what to do.
3. Search archived logs for threats
Probably, Among the most difficult attacks to detect are those that have been inactive for a long time on the internal network. With a SIEM they can be neutralized, with analytical tools to search archived logs for threats.
4. Activity tracking
A SIEM solution makes it possible to monitor the activity of users and devices used in each interaction on the same network. This fact helps detect signs of malicious behavior, such as compromised accounts or infected endpoints.
5. Protection against all kinds of threats
SIEM systems allow you to face any type of attack, as malware, ransomware, denial of service (From), phishing, worms, etc. At the same time, The best of all this is that it is possible to know what has happened in the systems.
Examples of SIEM tools
In Intellect let's both intellectually Azure Security Center That Monitor de Azure in SIEM solutions.
Azure Security Center
This Azure service, that can be integrated into SIEM solutions, uses a range of detection capabilities to alert to potential threats. These notices communicate what caused the alert, what was the goal, the origin of the attack and, if necessary, what measures to take. Anyway, it also offers flexibility to configure custom alerts and address specific needs.
Monitor de Azure
El enrutamiento de los datos de monitoreo a un centro de eventos con Azure MonitorAzure Monitor is a Microsoft tool that provides performance monitoring and analytics for applications and cloud services. Allows users to collect, Analyze and act on telemetry data in real time, facilitating problem identification and resource optimization. With its integration into the Azure ecosystem, Azure Monitor helps organizations maintain the availability and performance of their applications.... facilita la integración y el monitoreo con herramientas SIEM externas. And it is that Azure has partnered with the main SIEM partners to connect the data to these tools.
SIEM, an essential technology for companies
SIEM systems are a fundamental part of the data security environment. And it is that they collect data from numerous systems and analyze said data to identify abnormal behavior or possible cyberattacks or computer threats. They also provide a central point to compile events and alerts..
