Most Vulnerable Protocol

Most Vulnerable Protocol

[Sudhir Barwal]

Hi everybody,
     I'm sorry if it is of the topic, but I though this is the right place
to ask this.
I want to know that which is the most vulnerable protocol. I mean which is
the
protocol in which lot of vulnerabilities are there and can be hacked easily.
Why this question arises because somebody told me that SNMP is the most
vulnerable protocol.  After that I google but could not find satisfactory
link.
Any link, views are appericated in this regard.

Thanks.

Hi Sudhir

My first guess was, every protocol that is not encrypted is vulnerable
to the most basic attacks, e.g. password sniffing. 

However, on a second look, what does "a vulnerable protocol" mean? As
stated, if passwords and other sensitive data is not encrypted, it is
for sure not secure. But there are other issues that also influences the
security of network services: Is the receiving end vulnerable to buffer
overflows for example. Take a web server, the protocol, http, is clear
text, so all you need is a telnet client an you can talk to every web
server. Does this make the protocol vulnerable? Well, to a certain
degree yes, but it is more concerning how the web server reacts on
malformed packets. Same goes for snmp.

In my opinion, it's not the protocol that's vulnerable, the sending and
receiving ends are.

So with this in mind, have a look at:
* http://www.rfc-editor.org
* http://www.sans.org
* http://www.cert.org
* http://www.securityfocus.org/

regards
rafi

[Sudhir Barwal]

Thanks Rafael for the reply,

I waited for sometime so that I can reply to everyone at once.

I fully agree with your view that end points are vulnerable rathere than
protocol.
Actually what I mean was that which is the protocol having most no of
vulnerabilities?
(I suppose TCP). To manage my traffic passing from router I want to enable
snmp on
my cisco 3845 router, so whether it is safe to open that or not.
I'm giving public community with RO access.
I have put the iptable firewall before that.

Thanks.

Sudhir
