Yeah, it's up to their wishes.
But we should be able to make good decision and choice for our time spent.
The willingness to contribute is good but the willingness to
contribute in what it's most needed and most wanted is better.

Hello,

I would rather compare NMap scripts to OpenVAS plugins, which are both
GPL'd.
As NMap can be used as a port scanner in OpenVAS (through a dedicated
wrapper), I guess writing NSEs is somehow similar to writing NASL plugins,
isn't it? Do they address the same vulnerabilities?
Anyway, at the end of the day, developers are free to contribute to the
project they commit to the most... I guess...

Hi

Some of NMmap Scripts are now moving on for vulnerability scanning.
Those scripts are a smallest subset of what Nessus is now doing.

I have no idea why NSE folks write scripts that re-invent the wheel.
Although I appreciate that we have two options to validate the results,
a great deal of time will be wasted if NSE folks are
writing/converting Nessus plugins to NSEs.

How do you think?


Fyodor's got some excellent folks working for him to improve nmap, and
I'd strongly encourage anyone to re-think calling any of it a waste of
time!

I think nmap scripts are excellent additions to an already powerful
tool.  If there's some functionality overlap between some of those and
other existing tools, so be it.  As you say, there's value in a second
opinion to weed out false positives.  I also somewhat doubt they're
going about it primarily by reverse engineering Nessus plugins.

As another poster mentioned, Nmap is free, Nessus is not.  Bringing
commercial functionality and getting it into the hands of more people
is good for state of security.

To make an analogy to a different tool, yes, Core Impact has been an
amazing penetration testing exploit tool for a long time, but given
its price tag, how many people ever were able to leverage it to show
clients how easy it could be for a sufficiently motivated attacker?
Now that Metasploit (free) is staggeringly awesome as an exploit
framework, the argument for pushing vendors to fix their bugs, or for
organizations to apply lagging patches has become a bit more
compelling.  "A _free_ tool is avaialable with a plugin to exploit
this" is a lot more compelling to people than "There's this thing
called Core Impact has a sploit for this issue, but it costs [xx]
thousand dollars, and not many people have it."
