Cyber-attacks are becoming extremely regular, with a significant data breach entering the news almost daily. As a result, attackers are always looking for flaws in IT systems, apps, and infrastructure. To limit the damage, one of the most critical security strategies for preventing and combating assaults is to notice and respond to security incidents in real-time. SIEM (Security Information and Event Management) enables security teams to monitor security alerts. 

SIEM (security information and event management) technologies gather and aggregate log and event information to assist in detecting and tracking security breaches. It’s a robust service that gives enterprise security experts real-time visibility into what’s going on in their IT environment and a historical record of pertinent occurrences.  

SIEM tool collects and organizes log and event data created across an organization’s IT infrastructure, from host systems and apps to network and security devices like firewalls and antivirus filters. A SIEM solution aims to correlate signals in all that data to give security professionals the intelligence they need to identify and track breaches and other issues.

What Is SIEM?

Modern system security is often obtained by SIEMs that can collect data and analyse it in order to detect and stop (prevent) intrusions. The key purposes of these systems are finding threats, improving the investigation process, and reducing response time while providing a unified view of your infrastructure. 

The technology behind SIEM has evolved to give it more benefits than the log control systems before it. Advanced analytics and information on behavior help the system deal with constantly changing risks and regulations by gathering data.

SIEM Tools Provides

  • Real-time visibility throughout an organization’s information security systems with SIEM tools. 
  • Event log management combines data from a variety of sources. 
  • An analysis of events obtained from various logs or security sources using if-then rules to add intelligence to raw data. 
  • Notifications of security events are sent automatically. Most SIEM systems include security dashboards and other methods of direct notification.

  • EVENT & LOG COLLECTION: Monitor your event and log data with ease with this new network aggregator tool. 
  • DASHBOARDS: To make it easier for companies and analysts to spot patterns or anomalous activity in data, charts composed of collected data are commonly used. 
  • CORRELATION: This is a process of turning data into meaningful groups that can then be contextualized. Data is linked on the basis of their common attributes, and you can view this data in an effective timeline format. 
  • ALERTING: It uses automated analysis of correlated events to continuously monitor, trends, and audit. 
  • FORENSIC ANALYSIS: The ability to search across logs on different nodes and/or time periods. 
  • COMPLIANCE: Using new, automated apps to gather compliance and company data. Your data is then prepped for reporting, allowing for faster business processing.]

If you take this approach and implement a SIEM without genuinely understanding all the software does, you can run into many problems. A SIEM is more than just a product to place a proxy between your company and cybercriminals – it needs to know about all edge elements of your infrastructure for effective detection of attacks.

How Do SIEM Works?

SIEM combines two technologies: security information management (SIM), which collects data from log files for analysis and reports on security threats and events, and security event management (SEM), which monitors systems in real-time and notifies network administrators about critical issues and establishes correlations between security events. 

SIEM software gathers log and event data from an organization’s applications, security devices, and host systems and unifies it into a centralized platform. For example, SIEM collects data from antivirus events, firewall logs, and other sources, categorizing it as malware activity, failed and successful logins, etc.   

SIEM identifies risks, generates security alerts, and defines a threat level for acceptable and tenuous attempts. For example, if someone logs into an account ten consecutive times, this may be a typical login attempt. However, logging in 100 consecutive times would be an attempted hack.

While Some Systems Offer Advanced Skills, the Most of Them Have the Following Important Components:

IMPORTANT COMPONENTS in SIEM

Log Management 

SIEM collects event data from logs from various sources within a company’s network. It saves and analyses collected data in real-time to allow IT and security departments to manage the flow of data across a company’s servers, networks, and applications. 

Event Correlation and Analytics 

All SIEM solutions need event correlations. Event correlations can find and mitigate possible threats by providing advanced analytics that can identify intricate patterns in data. Systems such as a SIEM reduce weaknesses that might be found in the enterprise’s security by offloading manual workflows and performing vulnerability management analysis quickly.  

Incident Monitoring and Security Alerts 

SIEM systems enable organizations to centralize control and monitor the IT environment since they provide a platform that can be used for detection of and taking action on anything considered abnormal in a network. In addition, they have an extensive list of customizable correlation rules, enabling administrators to be warned when behaviour is deemed unusual and to take appropriate action to reduce any risk before it escalates into more severe damage. 

Compliance Management and Reporting 

SIEM solutions are a popular choice for businesses that comply with various regulations. SIEM is a powerful tool for gathering and verifying compliance data across the whole corporate infrastructure since it allows automated data collection and analysis. In addition, most SIEM solutions provide pre-built add-ons that can generate automated reports to meet compliance needs straight out of the box.

The Advantages of SIEM

It is always important to check for and mitigate internal IT security risks, no matter how big or small your company is. SIEM solutions are useful in optimizing security procedures because of their many benefits. Here are some of them:

ADVANTAGES OF SIEM

Improved Organization’s Efficiency 

SIEM can be an essential factor in enhancing interdepartmental efficiencies since it enhances the visibility of IT infrastructures. As a result, teams can communicate and coordinate efficiently when responding to perceived events and security problems with a single, unified view of system data and integrated SOAR. 

Users and Applications Are Being Monitored  

An organization needs the level of visibility required to mitigate network hazards outside the traditional network perimeter. Remote workforces, SaaS apps, and Bring Your Device policies have grown popular. SIEM systems monitor all network activity across all users, devices, and applications, allowing for greater visibility throughout the infrastructure and identifying threats irrespective of where data and applications or services are accessed. 

Detecting and Prevention of Complex Threats 

In today’s threat landscape, using an advanced SIEM is key to managing the strategic, tactical, and operational components of threat hunting — none of which can be ignored. To obtain better insight into potential threats, it’s critical to integrate SIEM as the centrepiece and cooperate with threat investigation tools. 

Monitoring for Regulatory Compliance 

SIEM solutions allow for centralized compliance auditing and reporting across a business’s complete infrastructure. Advanced automation reduces internal resource consumption while maintaining tight compliance reporting criteria by automating the collection and analysis of system logs and security incidents. 

Improved Situational Awareness and Reduces Responsiveness  

SIEM can use global threat intelligence to allow the quick detection of events involving communications with suspect or malicious IP addresses. As a result, attacking pathways and previous connections can be immediately identified, lowering response time and allowing for more fast environmental threat management.

Best Practices for Successful SIEM Implementation

Here is some SIEM implementation recommended practices:

BEST PRACTICES FOR SUCCESSFUL SIEM IMPLEMENTATION

Understand the Organization’s Requirements 

Begin by creating a clear image of your SIEM deployment’s criteria, including objectives, prioritized targets derived from those objectives, and the overall workflow. 

It’s a good idea to start with a clear picture of the SIEM use cases for your company. Then, inquire about what this solution will accomplish for your company and proceed. Finally, examine the security processes and policies that can support your proposed SIEM implementation and the existing controls to ensure compliance. 

Collect Maximum Data 

When it comes to transferring data into a SIEM system, more information is better because the principal objective of these tools is to take a large amount of log and event data and answer meaningful questions from it. However, without enough data, those problems couldn’t be solved. Begin with the most apparent data sources, such as network device and server logs. Other critical data sources, including identification and access information, vulnerability scanner results, and system configuration data, should not be missed. 

Classify Devices 

All digital assets in your organization’s IT system should be catalogued and categorized. This will be critical when collecting log data, detecting access abuses, and monitoring network activities. 

Refine Your SIEM Deployment on a Regular Basis 

SIEM does not support a “set and forget” strategy. Instead, extensive planning and gradual implementation are two recommended practices, but it’s also critical to establish a culture that promotes ongoing refinement and development. After all, hackers are developing increasingly sophisticated attacks, and staying one step ahead of them entails constantly improving the security features, rules, and processes available to you.
