SIEM

Why is SIEM so important?

Combining Security Information and Event Management (SIEM) and Security Event Management (SEM), Security Information and Event Management (SIEM) provides real-time monitoring and analysis of events, as well as tracking and logging of security data for compliance or auditing purposes. Provide a record. 

SIEM is a security solution that helps organizations identify potential security threats and vulnerabilities before disrupting business operations. A state-of-the-art Security Operations Center (SOC) for security use cases and compliance management uncovers user behaviour anomalies. It uses artificial intelligence to automate many manual processes associated with threat detection and incident response. It is becoming a staple.

Over the years, SIEM has matured beyond its predecessor, log management tools. Today, thanks to the power of AI and machine learning, SIEM provides advanced user and entity behavior analytics (UEBA). 

This is a highly efficient data orchestration system for managing ever-changing threats and regulatory compliance and reporting. 

How does SIEM work?

Insecure coding practices endanger customers and damage the company's reputation. For this reason, it is important to have a secure code.

All SIEM solutions perform data aggregation, consolidation, and sorting functions to identify threats and meet data compliance requirements at the most basic level. Some solutions have different capabilities, but most solutions provide the same core functionality: 

• Log management

SIEM collects event data from various sources throughout your organization's network. Logs and flow data from users, applications, assets, cloud environments, and networks are collected, stored, and analyzed in real-time, allowing IT and security teams to automatically collect network event logs and network flow data in one place. You can manage it. 

Some SIEM solutions integrate third-party data feeds to correlate internal security data with previously detected threat signatures and profiles. Integration with real-time threats allows teams to block or see new types of attack signatures. 

• Event correlation and analysis 

Event correlation is an important part of the SIEM solution. By using advanced analytics to identify and understand complex data patterns, event correlation provides insights to identify and mitigate potential threats to enterprise security quickly. The SIEM solution significantly improves IT security teams' Mean Time to Recovery (MTTD) and Response Time (MTTR) by offloading manual workflows related to detailed analysis of security events. 

• Incident monitoring and security alerts 

SIEM solutions can identify all entities in the IT environment to enable centralized management of on-premises and cloud-based infrastructure. 

This allows SIEM technology to monitor security incidents for all connected users, devices, and applications and classify them as soon as abnormal network behavior is detected. Customizable, predefined association rules allow administrators to receive alerts immediately and take appropriate action to mitigate security issues before they become significant.

Benefits of SIEM solution

Regardless of the size of your business, it is imperative to take proactive measures to monitor and mitigate IT security risks. SIEM solutions benefit organizations and have become key to streamlining security workflows. Some of the benefits are:

• Advanced real-time threat detection

 An active SIEM monitoring solution across the infrastructure significantly reduces the lead time required to identify and respond to potential network threats and vulnerabilities, helping to strengthen security as your business grows. ..

• Regulatory compliance audit

 SIEM solutions enable centralized compliance audits and reporting across the enterprise infrastructure. The high degree of automation streamlines the collection and analysis of system logs and security events, reducing internal resource usage while maintaining strict compliance reporting standards.

• AI-driven automation

 Today's next-generation SIEM solutions are integrated with powerful security orchestration, automation, and response (SOAR) capabilities, saving time and resources for IT teams to manage enterprise security.

These solutions can tackle complex threat detection and incident response protocols in significantly less time than physical teams, using deep machine learning that automatically adapts to network behavior. 

• Improved organizational efficiency

With the increased visibility of the IT environment provided by SIEM, SIEM can be a key driver in improving efficiency between departments. A unified view of system data and a built-in SOAR enable teams to communicate and collaborate efficiently to respond to perceived and security incidents.

• Advanced and unknown threat detection

 Organizations need to rely on solutions to detect and respond to known and unknown security threats, given the rapidly changing cybersecurity landscape. Using integrated threat intelligence feeds and AI technology, SIEM solutions can successfully mitigate the latest security breaches, including 

These attacks may result from a credential breach. Phishing attack A social engineering attack disguised as a trusted entity. Often used to steal user credentials, credentials, financial information, or other sensitive business information.

Data Theft – Data theft or extrusion is typically performed by abusing common or easily cracked passwords on network resources or using Advanced Persistent Threats (APTs).

Conducting Forensic Surveys

SIEM solutions are ideal for conducting digital forensic investigations when a security incident occurs. SIEM solutions enable organizations to efficiently collect and analyze log data from all digital assets in one place. This allows you to recreate past incidents, analyze new incidents, investigate suspicious activity, and implement more effective security processes.

SIEM implementation best practices

Consider the following best practices for SIEM implementation before or after investing in a new solution. Start with a complete understanding of the scope of your implementation. Define how your organization will maximize the benefits of your deployment and set up appropriate security use cases.
