SIEM for Advanced Threat Management

Security Information and Event Management (SIEM) enhances an organization’s security by proactively identifying and responding to threats and potential risks. SIEM systems help security teams identify suspicious user activities, and many of the threat identification and incident management processes are accomplished through AI integration.

Initially, SIEM platforms were designed as log management tools. They combined two essential functions: security information management (SIM) and security event management (SEM). These tools enabled tracking security incidents and facilitating security evaluation to enhance general security standards.
SIEM Market Trends and Growth:
  • Market Growth: The SIEM market is expected to grow at a CAGR of 14.5% annually and is estimated to reach $11.3 billion by 2026 from $4.8 billion in 2021.

  • Adoption Rates: According to the survey, 45% of organizations are using SIEM solutions.
    A study has shown that 82% of large firms depend on SIEM systems for security incident detection and response.

  • Incident Detection: Security organizations using SIEM tools are 28% faster in identifying security incidents than others.
Current Challenge:
The overall cost of a data breach increased to $5.2 million on the international scale in 2023, and in the United States, the scale was once again above $10.1 million. However, to this date, a global scarcity of cybersecurity personnel exists, and plenty of positions remain vacant. This state calls for adopting intelligent automation, particularly in these systems.

Thus SIEM will continue to be one of the critical components that help in building better security for digital structures as the year 2025 comes into progress. There is a need for choosing intelligent automation in SIEM solutions, which is much more paramount now that there are many various forms of cyber threats. This would mean efficient, large-scale log data analysis at essentially being in advance of emerging threats to your company.
How does SIEM work?
An SIEM system integrates data from all aspects of the organization’s network, providing improved visibility into user activity and overall system performance. They recognize possible threats according to specific security standards set for the organization. Some common data sources include:

  • Network Devices: Routers, switch-apparatus, wireless platform interface, etc.

  • Servers: Web, mail, Ftp, proxy server etc.

  • Security Devices: Firewalls, IPS, IDS, Antivirus, etc.

  • Applications: software used in network devices, security devices, etc.

Cloud and SaaS Solutions: Services and software that are not hosted on-premises.

Security Information and Event Management are important in today’s world of cyber security. These systems detect a number of metrics, including users, event types, source IP addresses, processes and so on. Siem tool detects anomalous activities such as attempted login or unauthorized changes to the account and notifies the security team to respond to it. Based on the detected alerts, SIEM can be configured to take certain actions, such as blocking certain activities or notifying the security specialists.

The ability to identify patterns and anomalies is what makes SIEM powerful. A login failure for example, may seem relatively negligible on face value, as it only occurred once. However, SIEM systems are intelligent enough to associate several such events across the diverse network, though identifying threats and notifying the concerned personnel to give it due consideration.

Another advantage of using SIEM is storing the logs in a database, which is an integral part of this system. All of this information can be further studied to increase an understanding of certain occurrences, explore a particular problem, or show adherence to the regulations. Besides using it to help security teams during an active threat situation, SIEM also seeks to solve matters and enhance security for future incidents. On that basis, SIEM becomes an efficient tool for safeguarding organizations from a wide array of constantly emerging threats.

Here is an example of how a SIEM system operates:

  • Data Collection: The SIEM system gathers logs originating from devices on the network, including firewalls, servers, and security cameras.

  • Log Aggregation: After the data is gathered, the SIEM system collects (or accumulates) these logs into a single system for analysis. It is as if all the material collected during an investigation is in one place.

  • Event Correlation: The system notices this a user from the finance department tries to log in at 3 am which is not a normal activity. Further, the SIEM system recognizes the fact that the user: login credentials have been utilized in attempts by the user to login into the system during the last a couple of hours with none being successful.

  • Real-Time Monitoring and Alerting: Due to such unusual activity, the SIEM raises an alert to the security team informing them of the possible threat (for instance, a person who attempts to gain access to certain kinds of data or tries to gain unauthorized control over an account).

  • Incident Response: After a security team looks into the situation, it disconnects the account immediately and changes the password to ensure that the unauthorized person does not log in again. They also monitor the system’s log files for the presence of any intrusion.

  • Reporting: Most SIEMs produce a report containing information such as incident time, the affected user, if the attack type was detected, and actions taken. It is also archived for incidental audits and compliance reviews of this report.

Why SIEM is Important?
  • Real-Time Threat Detection: In particular, SIEM enables organizations to identify security threats while the incidents are occurring. For instance, if an intruder attempts to login by entering the wrong password several times, the SIEM system will detect the invalid password attempts, and raise an alarm.

  • Faster Incident Response: SIEM makes it easier for security teams to deal with potential threats than ever before. It is easier to manage a threat if it is identified as early as possible. For example, if the SIEM system log indicates high traffic traffic, the security team can get in and analyze and stop any litigation that might have occurred.

  • Compliance and Auditing: SIEM also assists businesses to keep abreast with the ever changing regulation such as GDPR, HIPAA and PCI-DSS. It records and records the security activities and provide auditing reports that simplify the compliance regimen.

  • Centralized Monitoring: we don’t have to look at every device or application individually since an SIEM system provides a single console for the entire network. This makes detecting such anomalies easy and initiating a response when necessary.
