Should I disable port 135?
Hacker tools such as “epdump” (Endpoint Dump) can immediately identify every DCOM-related server/service running on the user”s hosting computer and match them up with known exploits against those services. Therefore, port 135 should not be exposed to the internet and must be blocked.
How do I close MSRPC port 135?
MSRPC is Microsoft remote procedure call. You can disable it by : goto run — type services. msc — search for RPC (remote procedure call) — stop/disable it.
What is DCE RPC used for?
DCE/RPC is an implementation of the Remote Procedure Call technology developed by the Open Group as part of the Distributed Computing Environment. DCE/RPC is most commonly used to interact with Windows network services.
What do you need to know about MSRPC?
TCP and UDP port 135 is used to negotiate actual communication over ports between 1025 – 65535. So, you need tcp and udp 135 and anything over 1024. MSRPC was created a long time ago and is not friendly to firewalls.
How to scan ports for ms15-034 vulnerability?
To get into scanning ports for the MS15-034 vulnerability we will need to download a NSE script, this is a script that defines parameters to execute a POC attack to prove the exploit is viable against the defined host.
Is the MSRPC protocol friendly to firewalls?
MSRPC was created a long time ago and is not friendly to firewalls. I typically open all ports to applications that require MSRPC protocol. Basically RPC sucks for firewalls. Microsoft should move to a less chatty transport protocol. But they won’t. EDIT: it’s analogous to FTP passive protocol.
Is there way we can scan for network vulnerabilities?
So is there a way we can scan for vulnerabilities in a “start and forget” sort of way? Sure, we can use Zenmap – Zenmap is a GUI built on top of nmap, a network scanner that can gather info on open ports, OS detection, etc.
