people with cracker skills operating within the law, e.g. in doing security

evaluations. All three terms derive from the dress code of formulaic

Westerns, in which bad guys wore black hats and good guys white

ones.</p></dd><dd><p> 2. [spamfighters] ‘Black hat’, ‘white hat’,
|
|||
|
|
and ‘gray hat’ are also used to denote the spam-friendliness of
|
|||
|
|
ISPs: a black hat ISP harbors spammers and doesn't terminate them; a white
|
|||
|
|
hat ISP terminates upon the first LART; and gray hat ISPs terminate only
|
|||
|
|
reluctantly and/or slowly. This has led to the concept of a <span class="firstterm">hat check</span>: someone considering a potential
|
|||
|
|
business relationship with an ISP or other provider will post a query to a
|
|||
|
|
<a href="../N/NANA.html"><i class="glossterm">NANA</i></a> group, asking about the provider's hat
|
|||
|
|
color. The term <span class="firstterm">albedo</span> has also been
|
|||
|
|
used to describe a provider's spam-friendliness.</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="black-art.html">Prev</a><EFBFBD></td><td width="20%" align="center"><a accesskey="u" href="../B.html">Up</a></td><td width="40%" align="right"><EFBFBD><a accesskey="n" href="black-hole.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">black art<72></td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"><EFBFBD>black hole</td></tr></table></div></body></html>
