What are the three main roles of SIEM?

The recent technology known as security information and event management (SIEM) quickly sorts huge data sets and automatically detects a range of threats. It can discover unusual behaviour and provide IT leaders with a real-time overview of their infrastructure.

This cyber security solution uncovers anomalies across all network applications from multiple hardware and software vendors. Additionally, it allows businesses to use a single security tool to monitor both their virtual environments and software-as-a-service (SaaS) solutions.

SIEM allows businesses to stay ahead of both internal and external security threats. It enables companies to respond to incidents more quickly through automation and intelligent alerts, by covering all of these attack surfaces and endpoints. SIEM is the ideal solution for compliance obligations because of its effective forensic and reporting capabilities.

It allows organisations to resolve various security challenges. Managing enterprise security is a tricky task because of growing networks and increasingly complex environments. Many enterprise networks may be vulnerable as a result of multiple vendors and solutions across cloud and on-premise infrastructure.

Advanced AI-driven algorithms used by SIEM to provide comprehensive surveillance ensure visibility across the entire IT network. What are the three main roles of SIEM, and what are the benefits for your company?

1. SIEM offers improved network visibility

SIEM offers a flexible solution that integrates with internal and external technologies, systems and vendors. It also supports multiple environments and provides excellent system visibility, retrieving data from all users, devices and applications on the enterprise network.

This increase in visibility is supported by a reduction in false positive alerts; security teams can be overwhelmed by too many false alerts. This problem is reduced by the use of intelligent systems, like SIEM, which makes it possible for security teams to identify and investigate potentially harmful threats. Through a centralised dashboard, all potential issues are catalogued, making them easier to identify and review.

2. SIEM uses automation to improve cyber security

SIEM aggregates data from a wide range of sources. This intelligent software identifies deviations from the set of parameters and pre-established rules. It can then proceed to take the necessary action. For instance, SIEM can identify a possible problem, trigger an alert and instruct automated security controls to stop the spread of suspicious activity. This reduces the time needed to address the cyber security concern.

When a cyber attack is detected, automated response capabilities kick in. Threats can be categorised based on their status and severity, and a remediation process can be launched right away. By ensuring that malicious codes and compromised data are quarantined, SIEM improves incident management. This can aid in preventing significant security breaches and containing them until a solution is found.

Through an intelligent cloud-based application, SIEM allows businesses to detect external threats, including zero-day threats. These so-called ‘zero-day’ attacks are increasingly prevalent; an unprecedented level of new types of attacks make computer systems vulnerable, particularly when they target weaknesses or blind spots.

SIEM offers sophisticated threat intelligence by detecting abnormal patterns of behaviour and identifying security system weaknesses before they can be exploited. This is done through advanced analytics and machine learning. It is effective in the face of ever-evolving threats and threat actors. Its monitoring capabilities become more accurate over time and SIEM can be scaled to meet your specific requirements as your business and network grows.

3. SIEM reporting supports compliance and forensic investigations

In industries that require strict compliance, SIEM offers a great deal of value. As an example, think about the financial sector. Card payment compliance has led to rapid adoption of SIEM technologies by large enterprises. By getting a bird's-eye view of the entire digital network, SIEM makes sure that banks can identify unusual patterns of behaviour.

In addition to data analysis, the IT system's users and other entities are constantly under observation. To ensure that all events are forwarded to a centralised management console, where automated tools or security analysts can identify and prioritise security threats, SIEM gathers insights from a variety of sources.

It makes it easy for enterprises to prioritise threats and filter massive amounts of information. Businesses can use it to gain a complete view of the network and identify incidents that could otherwise go undetected. SIEM's visualisation tools can be used to create a timeline of an attack. This makes it easier for forensic investigations to be conducted and ensures that organisations can identify the source and nature of the attack.
