Firewall port 8530 open

[Jobos]

I’ve discovered that the schools firewall has port 8530 open . As many will know this port is for client access to the WSUS server. I don’t know why or for how long 8530 has been open but it is and I can access WSUS from home using http://:8530/SimpleAuthWebService/SimpleAuth.asmx

 

This could be useful as it allows staff laptops to get updates without being brought into school but it’s also a security issue so should I contact Synetrix and get said port closed?

If you are happy to use it as a service then I would not worry about it.

 

I would just make sure that the machine hosting WSUS is suitably hardened and not available on other ports.
