Importance of SIEM

The reason an organization needs a SIEM solution to monitor the systems and report suspicious activities is that the amount of data an average organization generates nowadays is too much to handle manually. For instance, Gartner considers a SIEM system as small if it has up to 300 event sources, with events generating at 1,500 events per second. Large SIEMs handle thousands of event sources, generating more than 25,000 events per second.

The key ability of a SIEM is to filter through all the data and prioritize security issue alerts, making security more manageable. 
Log management sits at the core of SIEM functions; as the more diversified types of logs from more disparate sources feed the SIEM system, the more it generates actionable reports. This capability allows SIEM to correlate relevant events by cross-referencing logs from different sources against correlation rules

Current trends {Market Watch}

The report states that Security Information and Event Management (SIEM) Market gives detailed information on enterprises on a global and regional level through an all-inclusive analysis and insights into developments affecting businesses. It accommodates an entire overview of the market, including the market size, share, and the projection of this global market, within a specific interval of time. Then, it covers the major players functioning in Security Information and Event Management (SIEM) market

The future and relevance of SIEM is going to be dependent on the ability of software to adapt. These needs include integration with new technologies and increasing flexibility.

As a result, in 2020 we will most likely see

1. Stronger cloud management and monitoring capabilities
More companies are choosing cloud monitoring and management of their data. This is a convenient way for them to deal with all the data they collect from their clients. However, the cloud is not always secure so IT professionals strive to strengthen their own cloud monitoring and management systems internally to prevent security threats or breaches that may not be detected by their cloud service provider.

2. Better orchestration
SIEM currently offers basic workflow automation which has so far been quite efficient. But as companies experience growth, additional capabilities are required. In 2020, we will see more commercialization of machine learning and artificial intelligence which will call for faster SIEM orchestration so that different departments within an organization have the same level of protection. Security protocols and their executions will be faster and more efficient and effective.

3. Better MDRs-SIEM collaboration
MDRs stand for managed detection and response providers. These are outsourced professionals who take care of detecting, ascertaining and responding to threats.
Most time MDRs and SIEM are pitted against each other. They can, however, work together where the organization’s IT team implements SIEM in-house and the outsourced service provider also implements the MDR.

In 2020, threats of hacking and unauthorized access are likely to increase as technological advancements also increase. Having a two prong approach to detection and analysis of security threats is not only a good idea but also a prudent way to find a lasting solution. {Sources – Nexon}
