Exploring resilience and integration capabilities while navigating complexity and technical challenges

Logstash lacks a graphical user interface, necessitating a strong programming background to handle it effectively. It is challenging for business users who need a skilled team for its operation. Changing pipelines is not easy because Logstash requires pipelines to be programmed and cannot just be dragged and dropped like other data solutions. Additionally, Logstash does not automatically make actions based on the data it receives; integrating automation tools is required.

Improved threat detection and incident response has revealed training and usability gaps

What I would like to add is that if the interface or if there is less to work on technical knowledge. For example, people with no technical knowledge cannot use this, so they need to have at least a deep or substantial level of technical knowledge to be able to use these tools. If there is a way there can be an optimization to accommodate those with no technical knowledge in the process using tools compared to tools such as Sentinel and Splunk, which also doesn't require much technical knowledge to be able to use. That would also help. I think Security Onion could be improved by making the user interface more intuitive for new users and simplifying the initial setup and configuration process. Security Onion needs to be simplified so that those with less technical knowledge can be able to come in and use it. Guidance on prioritizing alerts will also be helpful, especially in an environment where security analysts deal with a high volume of security events. I also would like to mention that it needs to be more straightforward integration with other security tools. There needs to be a handshake between Security Onion and other same tools to help in endpoint detection and protection against threats. Another improvement that could also enhance is the reporting and visualization of the key metrics such as detection time, the incident, the overall interface of the analysis, and the false rate, which will also give Security Onion a better view for security analysts to be able to use and understand it. I would like to see the interface to be more simplified. I also would like to see the visualization to be more improved. I also would like to see the support features to be something that junior analysts or those coming in to start up their careers can be able to use without needing deep technical knowledge.

"What I appreciate most about Security Onion is that it combines multiple security monitoring tools into one platform."

"We use Security Onion for internal vulnerability assessment."

Cons

"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."

"Almost all the research can be very bad. We still have a problem with importing the log system."

"There can be a UI to implement with Logstash. Currently, I have to work with config files and everything."

"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."

"The product needs to improve its compatibility."

"The product is not easy to learn."

"One way Security Onion could improve is by making the initial setup and configuration easier, especially for new users."

"Security Onion's user interface could be improved."

"What I would like to add is that if the interface or if there is less to work on technical knowledge."

"One of the improvements for Security Onion could be to address the issue of many logs and false positive alerts by reducing the number of false positives, as storage management is very hard sometimes due to a lack of storage space for logs, and they could implement methods to expand storage."

"The biggest challenges I have experienced with Security Onion are the learning curve and resource requirements, as it is not necessarily something you can install and immediately understand without networking and Linux knowledge."

"Security Onion also has an enterprise version and support available; sometimes the community version is not capable enough to solve the purpose, so the enterprise edition can help."

"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."
