Generally discusses three types of attacks against computer
systems
1.Physical
A physical attack uses
conventional weapons, such as bombs or fire. A syntactic attack uses
virus-type software to disrupt or damage a computer system or network. A semantic
attack is a more subtle approach. Its goal is to attack users' Confidence by causing a
computer system to produce errors and unpredictable results.
2.Syntactic
Syntactic attacks are
sometimes grouped under the term "malicious software" or "malware".
These attacks may include viruses, worms, and Trojan horses. One common vehicle of
delivery formal ware is email.
3.Semantic
Semantic attacks involve
the modification of information or dissemination of incorrect information.
Modification of information has been perpetrated even without the aid of computers,
but computers and networks have provided new opportunities to achieve this. Also, the
dissemination of incorrect information to large numbers of people quickly is
facilitated by such mechanisms as email, message boards, and
websites
