Enhance Your Organization’s Cybersecurity with SIEM

Cybersecurity

What is SIEM?

An organization's most valuable asset is its data. You can safeguard your non-profit’s sensitive information with Security Information and Event Management (SIEM) solution.

SIEM is a tool that gathers and analyses data from many network and security systems to spot unusual behavior. It examines logs from your apps, firewall, and server to find trends that might point to a cyberattack.

According to the 2022 SIEM Report, more than 8 out of 10 businesses report improved threat detection after implementing SIEM.

What are the benefits of SIEM?

One of the benefits of SIEM is its ability to detect threats that other systems may have missed. Certain SIEM tools also try to combat attacks, presuming they are still happening.

Here are a few benefits of SIEM tool:

• Real-time protection: SIEM monitoring provides you with an active log and immediate notification of any potential threats.
• Customized alerts: SIEM can be tailored to specific needs of your NPO. So, you will only receive alerts that are relevant to your organization.
• Comprehensive security: SIEM provides a comprehensive view of your network's security. It helps you identify vulnerabilities and take action to prevent an attack.
• Scalability: You can leverage SIEM as a service at an affordable cost and with customization if you outsource it to an MSP.
• Expert support: You will have access to a team of cybersecurity experts who can help you with any questions or issues that may arise.

With SIEM, you can greatly enhance your non-profit’s cybersecurity and protect it from potential threats.

What are the three main roles of SIEM?

SIEM provides various security solutions for organizations. It helps you protect yourself from both internal and external attacks through alerts and automation. SIEM provides the comprehensive view of your entire security posture.

These are the three primary functions of SIEM:

SIEM enables Enhanced Network visibility:

SIEM provides a customizable solution that works in various environments. Technologies, systems, and vendors, both inside and outside the company, are integrated. The data that SIEM collects from all users, devices, and apps throughout your whole network gives it excellent visibility into digital systems.

When a cyberattack is discovered, SIEM activates automated response capabilities:
 

SIEM gathers information from a variety of sources. It identifies violations of the predetermined parameters and norms. The necessary action can then be taken.

When a possible problem is identified by SIEM, an alarm is set off, and automatic security measures are taken to halt the spread of suspicious behavior.

SIEM can identify flaws and offer suggestions to strengthen cyber security protocols using automated technologies.

By guaranteeing that malicious codes and compromised data are contained, SIEM improves incident management.

SIEM reporting aids in forensic investigation and proves compliance:

Enterprises can quickly filter massive amounts of information and rank threats thanks to SIEM. Businesses can use it to find incidents that might not have been seen otherwise.

SIEM's visualization tools can be used to build an attack timeline. This makes forensic investigations easier and guarantees that businesses can determine the origin and type of the assault.
 

SIEM tools offer crucial capabilities that can assist you in adhering to compliance requirements. System log collection and storage, ongoing event monitoring, threat identification, alerting, and reporting for incident response and investigation are all included in this.

 

What kinds of attacks can SIEM identify?

 

Implementation of Multi-factor Authentication and tools like SIEM will help you monitor employee activity and identify unusual patterns that may indicate an insider threat.

Insider threats can come from malicious employees who intentionally try to harm the company or from accidental actions by employees who may not be aware of the potential consequences of their actions.

 SIEM can also assist you in detecting modern-day security breaches such as:

1. Phishing attacks – Social engineering attacks are used to steal sensitive business information such as user data, login credentials, and financial information. However, SIEM creates an event in the case of an unusual authentication attempt.
2. SQL injection - A SQL injection attack manipulates queries by injecting unauthorized, malicious SQL statements through a compromised website or application. SIEM solutions can monitor activity from web applications and flag any abnormal activity.
3. DDoS Attacks - A Distributed-Denial-of-service (DDoS) attack is designed to bombard networks and systems with unmanageable traffic. This will slow down the service or crash it. SIEM would be able to flag such an abnormal event from web traffic logs and send it to an analyst for further investigation.
4. Data exfiltration- Data theft or exfiltration can be achieved with the help of easy-to-crack passwords on network assets or by using APT (Advanced Persistent Threats). The SIEM solution helps demonstrate a pattern of abnormal behavior, flagging it as a true concern that security analysts should investigate.

Not only will SIEM monitor your attacks, but it will also centralize and normalize the data streams.

What are the criteria for choosing SIEM? 

The characteristics of SIEM tools vary greatly, so it's crucial to assess your environment to establish your goals.

To find a SIEM solution that satisfies your requirements, consider the following seven factors:

 

1. Ability to manage logs: A SIEM tool should analyze each and every log that is generated. 
2. Correlate security incidents: The tool should be able to correlate security events and detect threats based on the correlation equations given. 
3. Reporting: The tool should have the capability to generate various types of reports, such as a time series report, an overall distribution graph, network traffic, and service usage. 
4. Going for POC: It is always suggested to go for a proof of concept when choosing a SIEM tool. Examine whether the SIEM tool's features and speed are compatible with your company's security requirements. 
5. Compliance: Consider the solution's ability to help you meet various regulatory and compliance requirements. 
6. Ease of Use: Ensure that the solution is easy to deploy, configure, and manage. 
7. Threat Detection: Consider the solution's ability to detect and respond to both known and unknown security threats.
