What about security vulnarability tools scanning RHDG ports?

Issue

• We run scanner to detect vulnerabilities which scan also the DG endpoints, should we avoid it?
• Should it be avoided to run security scanner to detect vulnerability against Data Grid ports?
• What to do if a security scanner detects a DG server is vulnerable?
• We have several WARN and ERROR messages found in our logfile, what is the purpose or it? Here some examples
