In the complicated digital space cybercriminals of every type constantly launch ransomware, viruses, phishing, and denial-of-service attacks that threaten your computer systems and network infrastructure. To ensure data and sensitive information always remain safe, companies need to develop security strategies that use a Security Information and Event Management System (SIEM). SIEM tools are capable of detecting, mitigating, and remediating different kinds of digital threats. In practice, SIEM focuses on providing security intelligence and real-time monitoring for network, devices, systems and applications.
The underlying principle of SIEM technology is that the relevant information about the security of an enterprise is produced in diverse sources, and the data is correlated and viewed from one central location. This process makes it easier to study the patterns and trends that are not allowed. The whole SIEM process consists of deploying multiple collection agents in a hierarchical manner to gather security-related events from end-user devices, servers, network equipment – and even specialised security equipment like firewalls, antivirus or intrusion prevention systems. Bearing in mind that the current computers and networks produce huge volumes of security log information, the SIEM system is required for handling of the increased level of information security as well as the analysis and management of centralized log.
PATECCO’s SIEM activities are spread into three groups: support of operation, support of compliance regulations and support of security analysis.
1. Support of operation:
The first step of a SIEM implementation is the deployment of Log Management. The logs of all relevant devices should be collected and stored. Log management tools help management quickly track down which pieces of data are missing and at the same time simplify regulatory compliance.
2. Support of Compliance Regulations:
A lot of relevant laws, policies and regulations have to be achieved in the modern world of enterprises and government. Regulatory compliance has been the most significant driver for the adoption of SIEM by organisations. Regulatory and legislative compliance demands also play a key role in log management adoption, being attributed for the increase deployment of log management tools by organisations and establishing log management as a permanent feature in the enterprise security architecture.
There are Core Elements of addressing Compliance Regulations which are the following:
- log all relevant events
- define the scope of coverage
- define what events constitute a threat
- detail what should be done about them in what time frame
- document when they occurred and what was done
- document where both the events and follow up records can be found
- document how long events and tickets are kept
3. Support of Security Analysis
With correlation of event data, a SIEM system can help to detect security breaches and advanced persistence threats. That means that SIEM technology supports threat detection and security incident response through the real-time event collection and historical analysis of security events, from a wide variety of event and contextual data sources.
Business benefits of SIEM solutions
Enterprises find SIEM necessary because of different factors such as rise in data breaches, need of managing increasing volumes of log from multiple sources and the requirements of adhering to stringent compliance requirements.
The business benefits of SIEM solutions are numerous, but the most essential ones are related to continuous information security risk and management processes, real-time monitoring (for operational efficiency and IT security purposes), cost savings, compliance, enhanced data protection and increased efficiency. SIEM also helps enterprises manage the increasing volumes of logs coming from disparate online sources. Storing the logs from different sources in a central secured database make the process of consolidation and analysis easier.
