Infrastructure Lead at Danat Fz LLC
Has provided reliable monitoring and alerting through extensive metric tracking and dashboard configuration
Amazon CloudWatch itself provides a lot of data. However, for visualization, we need to use third-party tools. We are in a process of integrating Grafana, Loki, and Prometheus to have better visualization on Amazon CloudWatch. We are also integrating Grafana with the application itself to get the application data and logs. Alternatively, there is AWS Kinesis and Glue where you can scrape the logs and have visualization, but a more easy option is Grafana. If you want to get a proper visual representation to see what is happening, then you need to integrate a third-party tool. Amazon CloudWatch has all the data, but to see what is happening, you need some third-party tool.

Centralized threat monitoring has improved visibility but demands complex setup and configuration
The best features Security Onion offers include acting as the intrusion detection system in my organization and helping me to address traffic, logs, and events happening within the organization. Since Security Onion is an open-source system that integrates with tools like Suricata and Zeek with the ELK stack, it enables threat detection and response capabilities, delivering high-level security measures at a cost, making it suitable for businesses of varying skill levels. These integrations with Suricata and Zeek have greatly impacted our workflow and our team's effectiveness by helping us address issues such as identifying intrusions, evaluating threats, and overseeing log files. This tool is very cost-effective, making it suitable for any size of organization wanting to use it.

Cons

"It is hard to configure; it is not a straightforward tool."
"Security Onion can be made easier to set up initially, as it is somewhat difficult at the start, but once configured, it becomes a great tool to use."

"For Security Onion, setting up and configuring the system can be quite challenging for newcomers due to the need for a grasp of networking and security concepts."
