As per a survey, the security information and event management (SIEM) industry generates a revenue of around $2 Billion, but only 21.9% of the companies could get the real value from SIEM.

Why is it so?

It is because they have not implemented the SIEM system, the right way.

If you are facing challenges in the right implementation of SIEM, or do not have much information about SIEM, then you are at the right place.

Below we are going to unravel the knowledge about SIEM and how it is important for every organization:

SIEM Simplified:

SIEM- It combines SIM and SEM

SIM means Security Information Management

SEM means Security Event Management

The tool helps in providing alerts generated with the help of hardware and the applications.

SIEM tools help to provide the real-time visibility to the security system of the organization. The system provides the dashboard for any challenges in the security. It offers a correlation of events accumulated from different security sources.

The software works with the combination of security information management that works in collecting the data from the files helping to predict the upcoming security threats. The security event management comes into next. It informs the network administrator of the correlations between the events that can increase security threats.

Why do companies need the SIEM tool?

Cybersecurity has become a grave concern for the majority of the organizations. For this reason, companies have been integrating SIEM systems to monitor the logs and find any suspicious activities that could harm the security of the organization. This helps to protect their information and sensitive data, a top priority for any organization.

The SIEM tool:

  • Follows the compliance obligations (NERC, FISMA, HIPPA, PCI, SOX, etc.)
  • Helps to gain and maintain the certifications(ISO 27000, ISO 27003, ISO 27001, ISO 27002)
  • Helps in the ticketing system

Who uses it?

SIEM is for the operations team, the security team and the compliance team.  The security team gets all the updated information, automation, and alerts so that they can plan ahead to mitigate the risks arising from any threats. The operations team gets the benefit from the SIEM tools for bringing the operations back to the process in case of any breakdown. They would also need the login details, and events to resolve the issue at the earliest.

And how does the compliance team use SIEM?

The data handling requires government regulation such as PCI, GDPR, HIPPA, etc. With the help of these regulations, the compliance team is able to make the security process effective and efficient.

How SIEM works?

SIEM provides the main capabilities to the incident response team, which are the alerts based on the analytics, and the reporting about the security incidents.

SIEM starts the work with the collection of data from all the configured devices. It then makes the data accessible to the security and other employees. The QRadar SIEM, for example, from IBM then analyzes the data, enabling the network admin users to quickly identify and stop the attack on time. It collects the events and flow of data from the applications that are cloud-based.

What is the role of SOC?

You must have heard about SOC in the security information and event management process.

Security operations center or the SOC, is the centralized unit that helps in dealing with the security issues on the complete level of an organization. The unit is equipped with the alarms, access monitoring, and others. The crucial people such as Tier- 1, Tier-2, and Tier- 3 analysts are the ones who rely on the security and information event management of the system.

What is SIEM analytics?

SIEM analytics, with the help of ML (machine learning) techniques, would help the security team to identify the threat and pattern with higher accuracy. This is often called as the next generation of SIEM that would block any harmful activities before it damages the system of the organization. It would have features like the pattern recognition, cloud-based analytics, and the log management with fully automatic capacity.

The components of SIEM architecture are:

  • Aggregation of data
  • Data intelligence feed
  • Correlating and monitoring of security
  • Analytics
  • To alert
  • Projection on dashboards
  • Ready with compliance
  • Retaining the historical data
  • Exploring event data
  • Identifying threats
  • Responding to security incidents
  • Security orchestration and response

The benefits of the SIEM software are:

  • It helps to prevent potential security breaches
  • Increases the efficiency of the system
  • It helps in better analyses and retention process
  • Saves the money
  • Is IT compliant
  • Helps to mitigate the security crisis

The key takeaways by implementing SIEM are:

  • It provides the security management system that helps in the centralized process.
  • It has the capacity to take the data from any in-house applications.
  • It provides a top-level view of the infrastructure of the system.

Some of the top SIEM companies are:

  • AT&T Cybersecurity
  • Dell Technologies
  • Exabeam
  • IBM QRadar
  • LogRythm
  • McAfee
  • Micro Focus Arcsight
  • ManageEngine

Conclusion:

Security Information and Event Management (SIEM) is a crucial part of the security of the organization. The service can be integrated for all sizes of businesses, be it small, mid-sized or the large enterprises. With SIEM, the cybersecurity of the organization is enhanced significantly.
