It is a common question, what is SIEM? SIEM (Security Information and Event Management) is the software that will give security professionals enterprises to track the activities of the IT environment. They are also able to record all the IT activities.
SIEM has existed for more than a decade and it is continuously evolving from the discipline of log management. It is combining the security event management which is analyzing the log and the events data in detail and in real-time. This will help in event correlation, threat monitoring, and also a response to the incident for security information management. The SIEM is also able to collect the data, analyze it, and then create the report based on it.
The SIEM software has evolved because of the need of organizations for better management of compliance. This software allows auditors to look at whether they are able to meet compliance or not. This is possible because of the reporting and monitoring which is needed to meet security mandates such as SOX, HIPPA, DSS, and PCI. SIEM provides better security to enterprise and it is used by big organizations as a foundation for setting up the operations center for security.
Benefits of Using SIEM
SIEM is the solution which is providing a very powerful method for the detection of threat, long term analytics, and real-time reporting for the security events and logs. This tool can be useful for the safeguarding of the company for all the sizes.
Benefits of SIEM include:
- Preventing security threats
- Increase efficiency
- Reducing costs
- Reducing the impact of the breaches in security
- Compliance to IT
SIEM is the solution that is able to collect the logs from multiple devices and applications. They are allowing the IT staff for reviewing, identifying, and responding to the potential security breaches very fast. When you are identifying the threat in the early stages then your organization will ensure that it will not suffer any of the minor impacts also.
In short, SIEM will allow the IT teams to see the wide picture when they will collect the security event data and logs from various sources in one place. SIEM will collect all of the alerts from the centralized console and then will allow the faster analysis.
Analytics and intelligence in SIEM:
The main driver which has increased the use of SIEM software in enterprise for security is the new capabilities of the software which is being included in most vendor SIEM products nowadays.
Threat intelligence is a common feature in most SIEM technologies which feeds additional information in the traditional log management data. You can find several SIEM products in the market that have capabilities of security analytics that analyze user behavior as well as network behavior in order to give better intelligence and check whether the activity is malicious or not.
You can also find advanced features such as advanced statistical analysis, machine learning, deep learning capabilities, and artificial intelligence as well. This provides better and accurate detection of cyber threats and that too at a fast speed. It also enables organizations to get analysis based on alerts, pattern-based monitoring, and predictive restoration. Nowadays SIEM software has transformed itself from a basic log management monitoring tool to software that provides remediation. It can even automate remediation to some extent in the near future.
SIEM tool for the enterprise:
Currently, SIEM software does not cover up a large portion of enterprise security systems on a global level. This is expected to grow manifold in the near future. Nowadays SIEM software is used increasingly by public companies and large organizations, where there is a strong need for regulatory compliance in the use of technology.
There are some mid-sized businesses that invest in SIEM software too, but small companies do not find the need to invest in SIEM systems. Also, small companies do not have the infrastructure and funds that are needed to maintain the SIEM software after installing it. Small and medium-sized businesses can get SIEM software from outsourcing providers who offer
SIEM systems as software as a service.
Mostly large enterprises use SIEM software on-premises because they do not want to share their company data over the internet. But nowadays it is quite secure to keep the SIEM system on the cloud or in a hybrid environment. This is because on the cloud it is possible to get advanced features such as artificial intelligence and machine learning.
