Cisco DoS Prevention

Discussion in 'Cisco' started by Martin Minnock, Jul 22, 2005.

  1. Hi,

    I've recently heard of a method of attacking Cisco routers based on the idea
    that they will sacrifice admin security in favour of continuing to correctly
    route when they are bombarded with packets.

    I have tried to recreate the problem on a Cisco 2600 series router in a test
    environment but cannot. (This is a good thing!).

    Two questions:
    1. Was this 'exploit' ever real or just an urban security legend?
    2. If it did exist how did Cisco fix the problem?

    Thanks,

    That sounds like a complete urban myth to me, I have never heard of
    such a thing. If it ever was an issue you can bet Cisco would have had
    that one stopped years ago.
