can security software like firewall that are installed on the main server protect all VPS running on the system or individual firewall needed for all VPS?
 
Yes and no. The hardware will need to have all of the normal ports open, whereas a VPS owner may only require certain ports be open. Also, some firewalls will not work well, behave consistently, with a VPS.
 
I can't remember for sure, but I believe it depends on the virtulization in use. Maybe someone else can elaborate.
 
it depends what virtualization is in use and for example in freevps/virtuozzo/openvz what kernel (firewall) modules are loaded on the hardware-node (main server)
 
Hey there,

Each VPS needs to have its own firewall for the most security. Most (managed, at least) providers, offer free security hardening for you - in which a firewall is typically installed.
 
VPS Firewall

A main firewall on the node would effect all VE's underlying. It would be fine if you were the owner of all the VE's, but for a hosting company this would not make much sense.

So software would be only option for those not owning the hardware node.
 
Yes firewalls will run on VPS servers depending on if the hardware node is set up properly

We install a firewall on every VPS server :)
 
True. I use CSF and mod_security for my vps. It's help allot, specially blocking repidleech and proxy websites.
