You would have heard the term wireless technology very often. Wireless technology is the talk of the day. The WAP is the technology designed for use with wireless devices. Many manufacturers, including Mototola, Nokia, and others have adopted WAP as a standard. WAP functions are equivalent to TCP/IP functions in that they are trying to serve the same purpose for wireless devices. WAP uses a smaller version of HTML called Wireless Markup Language (WML), which is used for internet displays. WAP-enabled devices can also respond to scripts using an environment called WMLScript. This scripting language is similar to JavaScript, which is a programming language.
The ability to accept web
pages and scripts produces the opportunity for malicious code and
viruses to be transported to WAP-enabled devices. This creates a new
set of problems, and antivirus software must be able to deal with
them.
WAP systems communicate
using a WAP gateway system. The gateway converts information back and
forth between HTTP and WAP, and it also encodes and decodes the
security protocols. This structure provides a reasonable assurance
that WAP-enabled devices can be secured. If the interconnection
between the WAP server and the Internet isn't encrypted, packets
between the devices may be intercepted, creating a potential
vulnerability. This vulnerability is called a gap in the WAP.
