Hello All,

Anyone from the network security or related to tht field could please
elaborate the difference between Advanced Encryption Standard(AES) and
Intrusion Prevention System (IPS), or they are one and the same??
I went thru wikipedia, bt cldn't figure out the differences between
thm, if any.

Thanks in advance for your inputs

Regards,
Ank


Re: AES vs IPS
Hi,

They are two different "things".

AES is an encryption algorithm like DES, Twofish, etc.
An IPS instead is used just as its acronym suggests: to prevent an intrusion
to a protected network. There are many kinds of methods to do this: some of
them are: using a pattern to discover "bad things" entering the protected
network, use a statistical approach to determine anomal traffic entering the
protected network, etc.
An IDS ( Intrusion Detection System ) is like an IPS but it only monitors
the traffic ( so it has not to be "in-line" ) and do not proactively protect
the network ( it just logs ).

I just give you a small ( not very accurate and surely not comprehensive )
picture.... online you can find lots of info about this subject.

This is not true at all. IDS can of course be proactive, it can send shuns,
tcp resets and even ACL's to a device to block the traffic, it does a whole
lot more than just log. IPS can act the exact same way, it can also be
configured to simply drop the traffic as it passes thru, or it can be
configured to just log. The advantage to IPS is a faster reaction time
against the attack. In the milliseconds it takes for IDS to send the
commands to a blocking device the IPS could have already droped the traffic.

Re: AES vs IPS
Hi,

yes, you're right regarding current IDS capabilities.
However if an IDS is put on an RMON like port it cannot block traffic
itself, it can only log or act by signalling other devices to do something.
Current generation IDS and IPS have more things in common then not.

IPS is designed to detect attempts to hack into computer networks.

AES is used to encrypt data

They are completely different. I suggest you look at wikipedia again.



Re: AES vs IPS
Thanks to all who had put their comments on to get my doubts cleared.

Thanks once again
