[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: [FW1] OT - newbie question about PING
Any protocol you let though a firewall has the potential to cause harm, expecially if anyone in the world can do it. In ping's case (IIRC) some systems are susceptable to DOS attacks from partial packets or any other exploit relating to ICMP. Memory is getting vague here , but if you allow ping you probably allow traceroute. this would give a hacker an ability to map your network... Not A Good Thing (tm) IMHO -----Original Message----- From: John Hahn [mailto:[email protected]] Sent: Tuesday, 3 July 2001 11:40 PM To: [email protected] Subject: [FW1] OT - newbie question about PING Would someone please explain the reasoning to not allow PING through the Firewall to our internal networks? I've having a problem justifiying to the mainframe systems group why I will not globaly enable PING. Your thoughts would be appreciated.
