Security information and event management or SIEM does next-generation detection, analytics, and response for organizations. It pools together security information and security event management to provide real-time analytics of security alerts. This gives security professionals data and insights about the activities happening within their IT environment.
How SIEM works?
The most fundamental function of the SIEM system is to gather relevant data from various sources, identify abnormalities, and carry out appropriate action.
Specifically, SIEM software combines log data from the organization’s technology infrastructure, host systems, and applications. This may include antivirus events, firewall logs, and failed logins.
After the data has been brought together into a centralized platform, it categorizes incidents and events, and evaluates them. Once a potential issue is spotted, the SIEM system may log additional data, create an alert, and instruct security controls to halt an activity’s progress.
Basically, SIEM solutions seek to accomplish the following objectives:
Generate reports on security-related events such as malware attacks and other malicious activities.
Send alerts if they determine that an activity is going against predetermined guidelines because they may be a potential security issue.
Benefits of SIEM to Organizations
Security information and event management tool can provide the following value to organizations:
1. Collect and analyze data from various sources regularly
Companies are producing more and more data than ever. To keep up with this growth, SIEM solutions take in data from all sources and monitor them. This allows IT security staff to detect and respond to potential threats immediately. The more data your SIEM collects, the more aware your analysts will be of any malicious incidents.
2. Increase efficiency
Cyberattacks have become more sophisticated. As such, organizations are required to have advanced tools to protect their network. Attackers use compromised credentials or take advantage of the user’s vulnerability to perform actions that could damage the entire organization.
To identify attacks more swiftly, SIEM tools have machine learning abilities that enable them to track suspicious user behaviors. This limits false positives, so security analysts focus their time and resources on more critical threats.
3. Saves time
Modern SIEM solutions can be easily implemented on virtual environments or on-premise. SIEM takes only a short time to install and requires low maintenance resources, providing value to your business.
4. Makes investigations easier
Security information and event management provide analysts with the knowledge they need to make better decisions and improve response time. With data visualization and smart business context, security analysts are able to interpret and respond accordingly based on what the data tells them. Better analytics can help teams be more efficient in managing incidents and developing their forensic investigations within a single platform.
5. Meets compliance
Compliance requirements have been more prevalent, and this puts pressure on enterprises. With tighter compliance regulations, businesses need to invest in robust IT security like SIEM. This tool plays a significant role in helping organizations comply with PCI DSS, GDPR, and HIPAA, among others. SIEM can be used by any businesses, irrespective of their size.
6. Allows security analysts to focus on other tasks
Modern SIEM tools can free up the time of security analysts by automating some manual tasks. Aside from utilizing user behavior to generate insights, they also automate threat detection and provide enhanced context and situational awareness. Their unsupervised machine learning can even ease the burden of overworked analysts so they can work on other tasks.
7. Predictable pricing
Security information and event management pricing usually charges you for the number of devices that are sending logs. This means you don’t have to worry about your data usage affecting costs. Concurrently, this allows you to allot your savings for your business’ future needs. Just make sure to consider the total cost of ownership, especially if your SIEM tool needs to scale.
