open ports on a router?
I have these ports open on a router is this ok? Or should I fix them immediately? thanks for any help
Port State Service 21/tcp open ftp 23/tcp open telnet 389/tcp open ldap 500/tcp filtered isakmp 1002/tcp open unknown 1720/tcp open H.323/Q.931 |
Telnet is kinda a bad idea, not really a hazard unless you're actually using it. Same with ldap and ftp, they both let passwords fly back and forth without any encryption. Basically, if you're not using any of those services, yeah, turn them the heck off.
What kind of router is it that has 1002 and 1720 open by default? Cheers, Finegan |
its an adtran 3200 I turned NAT on but I dont even know what those ports are, can I turn telnet off from a telnet session? or do I have to be hooked into from the serial port? thanks for the quick reply! I will close them as soon as I figure out how
thanks again |
This looks like the best place to start... of course it gets grumpy with anything but I.E. > 5.5
