What is SIEM? And How Does it Work?
Don’t know what to do when you have a system security breach? Then read about SIEM tools to ensure the safety of your system and protect your business against unknown threats.
Quick Summary: Cybersecurity is of utmost importance for everyone, but it is impossible to detect every threat. But it is impossible for organizations to detect every threat and manage security. Thus, if you are an organization suffering such challenges, then SIEM is for you. So, here is a detailed explanation of SIEM, its uses, and its benefits.
Introduction
With the new technology taking over the world, the internet conveniences everyone in performing almost any task in a matter of seconds, but it also comes with a slew of dangers. The fact that cyber attack news does not sound shocking anymore says a lot. The second quarter of 2022 went with approx 52 million data breach reports. The only relief was that the number reduced by 56% compared to the last quarter. However, 2020 still tops the list for most data breaches at nearly 125 million cases.
Security incidents with regular break-ins and data breaches have become a usual occurrence. Virtual attacks can bring your business to the ground in less than a second. And the depressing part is that you can be the reason behind a breach or tampered data owing to the inefficient security measures in your company. Unknowingly clicking on a random or strange link or email invites the attacker into your company’s network. All of this, however, can be avoided by implementing a diligent security platform in your company. A platform that will effectively respond to all the threats and detect the danger before it knocks on your door. And that is where SIEM comes into the picture!
Read ahead to learn what SIEM is, how it works, benefits an organization, and if you should utilize this meticulous platform!
What is SIEM?
SIEM stands for Security information and event management. It helps detect vulnerabilities and security breaches that threaten an organization’s servers. SIEM tools offer a specific location to gather events and data from servers, network devices, domain controllers, etc., making them easily accessible when needed.
SIEM is an efficient data orchestration system that manages evolving threats and defuses them. Searching for potential harm in the entire organization’s digital framework is exhausting and daunting when done manually. SIEM analyses activities and information and alerts the security team if it detects any suspicious activity. With the help of AI and machine learning, it offers advanced user and entity behavior analytics (UEBA).
How does SIEM work?
SIEM collects data from the system’s servers and analyses them to provide a holistic view of a company’s information technology. It investigates and solves suspicious activities and ensures that the system has an efficient security system.
- It collects data from networks, servers, devices, etc.
- After collecting the data from various networks and servers, SIEM aggregates them.
- Then it analyses the data for anomalies, threats, or trends.
- After SIEM detects data for threats and anomalies, it investigates them, identifies the dangers, and takes immediate action to protect the networks, servers, and devices.
- SIEM performs real-time analysis to detect threats and anomalies. This saves time and effort. It also ensures that all future threats that follow the same trend are dealt with. After threat detection, it provides an appropriate solution to keep the system safe.
- SIEM is a search and report system. After taking action against the detected threat, it gives reports.
What is the importance of SIEM?
SIEM collects data from networks, devices, servers, and domains and analyses them to detect threats against the system, investigate them, and provide appropriate and accurate solutions.
- Easy security management
It is challenging to manage the entire system’s security. You can simplify the process by filtering millions of data within seconds and prioritizing the security alerts generated by the software using the SIEM solution. It allows the integration of risk assessment services and aids the security team in determining the nature and impact of an attack on your business.
- Detecting threats
The lack of a proper security platform permits unauthorized external users to enter the company’s network unnoticed. Besides adversely impacting your reputation, it exposes you to regular security incidents. SIEM performs a thorough detection process and alerts the security team in real-time in case of an unknown user or activity in the system. It further allows you to take adequate provisions to deal with the threat.
- Regulation of compliances
Organizations must adhere to some rules and compliance frameworks, like HIPAA, to stay in the market for the long run. But it is arduous to implement a security structure that follows the set rules and ethics and avails you of retrieving the log data quickly. However, the SIEM solution allows you to generate reports about the logged security events while meeting the compliances.
- Data Intelligence
SIEM tools assist in resolving the underlying threats and detecting any future risks. It provides the security team with relevant insights through computer software and aggregated databases. With the implementation of data intelligence, SIEM offers your IT team several additional features such as system access management, quick data encryption, quality management services, SSO integration, etc.
What are the benefits of the SIEM to an organization?
Regardless of the success of your enterprise, taking necessary steps to monitor and remediate IT security threats is essential. Solutions provided by SIEM are beneficial and can become a significant asset. Some of the benefits include:
- Advanced real-time threat identification
With its extensive tools, SIEM analyzes the data collected on the organization’s server in real time. Identifying and providing solutions for potential security threats and anomalies takes relatively less time. This helps organizations strengthen the system’s security.
- Flexible and adaptable
Organizations produce data in large volumes. Big data structures are required to store this sheer amount of data and ensure its availability at all times. Therefore, companies look for flexible, scalable, and adaptable frameworks to retain data securely. Present-day SIEMs can deploy in the cloud or on-premises virtual environments and efficiently handle complex implementations.
- Automated threat detection
SIEM frees the analysts and security team from engaging in manual tasks. It utilizes machine learning and performs automated threat detections regularly to locate any danger. It helps gain better insights into the security system by providing enhanced context, threat intelligence, and user behaviour.
- Enhances situational awareness
The landscape of cyber security changes very quickly. Cyber attacks are becoming more efficient with well-planned strategies. As a result, organizations rely on solutions that can accurately analyze, detect, and provide solutions for unknown threats. SIEM uses threat intelligence tools and AI technology to detect unknown threats and security breaches instantly.
