Are there any security concerns with OSPF packets?

My company is about to get a security audit next week and I'm trying to tighten up my network. I'm not sure if it's normal but I am getting OSPF Hello Packets on all of my VLAN interfaces. I only use OSPF on the main switch that talks to our core router. We usually do static routes at all of our locations so these packets only show up on this one network that uses OSPF. We only do static routes to adjacent IDFs in our buildings.

The switch is an HP 5820 running Comware 5 plugging into a Cisco 6880.

I'm thinking the hello packet isn't that big of a deal. I was thinking of adding

ospf network-type p2p 

to the interface ten 1/0/24 on the HP 5820. I'm going to wait until after hours though before I try that.

The Cisco is owned by my ISP so I don't like making changes on it but I can if I have too. I'm more comfortable with HP Comware anyway.
