Benefits of SIEM
SIEM is a solution that assists businesses in detecting, assessing, and mitigating security risks before they affect regular operations.
Introduction
The goal of a security information and event management (SIEM) solution is to remove attackers from a system by collecting data from throughout the firm, normalizing it so it can be searched, analyzing it for anomalies, and then investigating events and fixing issues.
The use of distributed architecture by businesses is at an all-time high.
When an architecture’s design is intricate, there are more weak points that a malicious actor can exploit.
The possibility of a cyber attack on the company is so increased.
There is much more data for monitoring suspicious activity than any analyst could ever evaluate.
The analysts are looking for tools to help them identify the most critical incidents that need additional examination and flag any policy breaches that demand prompt action.
Evolution of SIEM
SIM and SEM
In the 1990s, IT security was primarily concerned with preventing unauthorized access to the inside of a network.
At the time, solutions were very straightforward, falling into two categories: security information management (SIM) and security event management (SEM).
Also, early systems were built on proprietary databases, which limited their applicability and locked customers into the services of a single vendor.
SIEM
As data prices have dropped and technology has advanced, SIEMs have increased their ability to consume, process, and store data.
It was a huge advance when SIEMs began employing signature-based alerts to find threats in your data.
This SIEM generation, however, also had several serious flaws.
Signatures meant they could only find threats that had already been recognized — their inability to detect new or previously unseen hazards substantially impacted their performance.
Next-Generation SIEM
Designed for usage in the cloud and constructed on a big data platform with unlimited scalability.
Next-generation SIEMs consolidate several functions into a single, streamlined interface, including log management, advanced threat detection using behavior analytics, and automated incident response.
Benefits of SIEM
It is necessary for every business, regardless of its size, to take preventative measures to monitor for and eliminate potential threats to its information technology infrastructure.
SIEM solutions are advantageous to businesses and have become important in optimizing security procedures. The following are some of the advantages:
- Recognition of advanced threats in real-time
SIEM active monitoring solutions throughout your entire infrastructure greatly decrease the lead time necessary to discover and respond to possible network threats and vulnerabilities.
This helps to enhance the security posture of the business as it expands.
2. Regulatory compliance auditing
SIEM systems make it possible to conduct centralized compliance audits and reporting across an organization’s infrastructure.
The collection and analysis of system logs and security events may be streamlined with advanced automation.
This helps decrease the number of internal resources utilized while maintaining tight compliance reporting criteria.
3. AI-driven automation
The next-generation security information and event management (SIEM) systems currently interact with sophisticated Security Orchestration, Automation, and Response (SOAR) capabilities.
This helps IT organizations save time and money while managing corporate security.
These systems can handle complicated threat detection and incident response procedures in a substantially shorter time than physical teams because they use machine learning techniques that are so advanced that they automatically adapt to the behavior of the network.
4. Improved organizational efficiency
SIEM can be a key driver in enhancing interdepartmental efficiency because of the greater visibility of the IT infrastructures it delivers.
When reacting to perceived events and security issues, teams may communicate and coordinate quickly with one another if they have access to a single, unified view of system data and an integrated SOAR.

5. Identifying Complex and Unknown Security Threats
With the rapid pace at which the cybersecurity landscape evolves, businesses need to depend on solutions that can identify and react to known and undiscovered security threats.
SIEM systems may effectively guard against various security breaches by integrating threat intelligence feeds and AI technologies. Some examples of these types of breaches include the following:
- Insider threats
- Phishing attacks
- SQL Injections
- DDoS Attacks
- Data exfiltration
6. Conducting Forensic Investigations
After a security breach, using SIEM systems to undertake digital forensic investigations is the best course of action.
SIEM systems enable enterprises to effectively gather and analyze log data from their digital assets in a centralized location.
This allows them to examine suspicious activities and adopt more effective security procedures by recreating prior occurrences or analyzing new ones, giving them the power to do so.
7. Conducting Compliance Audits and Providing Reports
Auditing and reporting compliance standards is a duty that is not only important for many businesses but also one of the most difficult.
SIEM systems provide real-time audits and on-demand reporting of regulatory compliance whenever necessary, which allows for a tremendous reduction in resource expenditures required to handle this process.
8. Keeping an eye on both users and applications
Because of the surge in popularity of remote workforces, SaaS apps, and BYOD (Bring Your Own Device) policies, enterprises require the visibility essential to manage network hazards that originate beyond the traditional network perimeter.
SIEM systems monitor all network activity across all users, devices, and apps. This dramatically improves transparency across the whole infrastructure and allows for detecting threats no matter where digital assets and services are accessed.
