Query: Encoding a Taxonomy of Web Attacks with Different-Length Vectors   Web attacks, i.e. attacks exclusively using the HTTP protocol, are rapidly
becoming one of the fundamental threats for information systems connected to
the Internet. When the attacks suffered by web servers through the years are
analyzed, it is observed that most of them are very similar, using a reduced
number of attacking techniques. It is generally agreed that classification can
help designers and programmers to better understand attacks and build more
secure applications. As an effort in this direction, a new taxonomy of web
attacks is proposed in this paper, with the objective of obtaining a
practically useful reference framework for security applications. The use of
the taxonomy is illustrated by means of multiplatform real world web attack
examples. Along with this taxonomy, important features of each attack category
are discussed. A suitable semantic-dependent web attack encoding scheme is
defined that uses different-length vectors. Possible applications are
described, which might benefit from this taxonomy and encoding scheme, such as
intrusion detection systems and application firewalls.
