Introduction
Unwanted
and irrelevant mass mailings, commonly known as spam are becoming a serious
nuisance that if left unchecked may soon be regarded as a Denial of Service
Attack against the email infrastructure of the Internet itself.
Best Practices
The
traditional response of the internet to problem uses administrators of deployed
protocols is to specify some form of 'Best Practices'. Spam is an attack on the
Internet community. The short survey and prosecutions by the FTC and others
show that the spam senders are in many cases outright criminals, how then can
best practices help? One area in which best practices can provide concrete
benefit is in ensuring that the vast majority of Internet users who are acting
in good faith do not inadvertently make the problem worse by poorly chosen or
poorly coordinated mitigation strategies.
Naive Keyword
Inspection
Messages
are scanned for the presence of words or phrases that occur frequently in spam
messages such as HGH or multi-level marketing. This type of filtering is
implemented in many common email clients such as Outlook [MSFT]. Keyword Inspection alone is simple to
implement but tends to have very high rate of false positives.
Authentication And Authorization
Practically
all spam messages sent today attempt to evade anti-spam measures by use of
false header information. None of the spam messages that were examined in the
writing of this paper carried a genuine sender address. Most of the massages
contained from addresses that were obviously fake. In some cases the addresses
were not even valid. Some contained no sender address at all.
Legislation And Litigation
The
purpose of criminal legislation in a democratic is to deter persons from
engaging in prohibited conduct. While it is unlikely that the criminal
legislation alone would eliminate spam. Such legislation would certainly create
a deterrent for both the spam senders and the advertisers seeking their
services. The legislative process is very slow & time consuming.
Legislators are reluctant to pass any legislation until they are confident that
the implications are fully understood. Legislators will have to be convinced
that any new legislation to address the problem of spam will bring benefits
that significantly outweigh both the cost of enforcement and the political cost
of committing the scarce resource of legislative time to the problem of spam
rather than to other pressing problems.
Conclusion
There
are many techniques that address a part of the spam problem. No currently known
technique provides a complete solution and it is unlikely that address a part
of the problem. No currently known technique provides a complete solution and
it is unlikely that any technique will be found in the future that provides a
complete and costless solution.
