SIEM or Security information and event management is a set of tools that combines security, event & management and security information management. These both systems are very closely related to each other.
Security Information Management refers to the method of collection of data combined into a specific format, such as the log file. That format is then placed in a centralized location. Once log is formatted and location for your data, it can be analysed easily and quickly.SIM relates only to the data collection techniques used to find problems within a system.
SIEM provides real-time system monitoring and fire notification to network administrators about potential issues.
What are SIEM Software Tools?
Server software sends log information to a central portal. This is typically a centralized server as they have more security monitoring than in-house hardware.
SIEM Software console provides clients visual aids filtered through local parameters. Cybersecurity incidents and events can be identified, recreated, and audited through accounting logs.
Flow of Security Information Event Management
Security Information and Event Management also works by monitoring and logging data. Most SOC experts consider SIEM tools to be more than a simple monitoring and logging solution.
Top SIEM Tools and Software Solutions of 2020
Open source SIEM used most often as a host-based system for intrusion prevention and detection system. OSSEC works with all OS like Solaris, Mac OS, Linux, and Windows servers. OSSEC allows direct monitoring for rootkit detection, file integrity, and log files. It can also connect to mail, FTP, web, firewall, and DNS based IDS platforms.
Two components comprise OSSEC:
1. the host agent and
2. The main applications.

McAfee is Best for mid to large companies searching for a complete security event management solution.
ELK may be the most popular solution these days. ELK is the combination of products Elasticsearch, Logstash, and Kibana.
Elasticsearch provides the engine to store data. Logstash can receive your log data from any device. It can also enhance, process, and filter your log data if needed.
Kibana gives you your visuals after accepting data from Logstash.
ELK stack forms the base of many commercial Security Information and Event Management platforms. Each program specializes, making the entire stack more stable. This is an excellent choice for high performance and a relatively simple learning curve.

Logstash is one of three software solutions that work together to create a full SIEM system. Each application can be used with the other tools as the user sees fit. Each product can be regarded as SIEM software but used together they form a SIEM system.
Logstash collects log data from the network devices and transfer them to file. Logstash helps to manage which types of records want to ship and also can ignore specific sources.
Logstash has its own record format, and the Logstash file interface can reinterpret the data into other forms.

Prelude is the platform that combines them all. It fills in certain holes that Snort and OSSEC do not prioritize.
Prelude gives you the ability to store logs from multiple sources in one place. It does this using IDMEF technology (Intrusion Detection Message Exchange Format). You gain the ability to analyze, filter, correlate, alert, and visualize your data. The commercial version is more robust than the open-source version. If you need top performance, go commercial.
