2 Ensure that the install tipc /bin/true line appears in this le.
3 Save the le and close it.
Secure Internet Packet Exchange Protocol
Prevent the Internetwork Packet Exchange (IPX) protocol from loading vRealize appliances by default.
Potential aackers could exploit this protocol to compromise your system.
Avoid loading the IPX protocol module unless it is absolutely necessary. IPX protocol is an obsolete
network-layer protocol. Binding this protocol to the network stack increases the aack surface of the host.
Unprivileged local processes might cause the system to dynamically load a protocol handler by using the
protocol to open a socket.
Procedure
1 Open the /etc/modprobe.conf.local le in a text editor.
2 Ensure that the line install ipx /bin/true appears in this le.
3 Save the le and close it.
Secure Appletalk Protocol
Prevent the Appletalk protocol from loading on vRealize appliances by default. Potential aackers might
exploit this protocol to compromise your system.
Avoid loading the Appletalk Protocol module unless it is absolutely necessary. Binding this protocol to the
network stack increases the aack surface of the host. Unprivileged local processes might cause the system
to dynamically load a protocol handler by using the protocol to open a socket.
Procedure
1 Open the /etc/modprobe.conf.local le in a text editor.
2 Ensure that the line install appletalk /bin/true appears in this le.
3 Save the le and close it.
Secure DECnet Protocol
Prevent the DECnet protocol from loading on your system by default. Potential aackers might exploit this
protocol to compromise your system.
Avoid loading the DECnet Protocol module unless it is absolutely necessary. Binding this protocol to the
network stack increases the aack surface of the host. Unprivileged local processes could cause the system
to dynamically load a protocol handler by using the protocol to open a socket.
Procedure
1 Open the DECnet Protocol /etc/modprobe.conf.local le in a text editor.
2 Ensure that the line install decnet /bin/true appears in this le.
3 Save the le and close it.
Secure Firewire Module
Prevent the Firewire module from loading on vRealize appliances by default. Potential aackers might
exploit this protocol to compromise your system.
Avoid loading the Firewire module unless it is absolutely necessary.
