| | Determine the differences between a denial of service email attack
from a typical denial of service attack on a user/domain to create a
definition of a denial of service email attack
Types:
Bandwidth consumption
Network connectivity
other types
bandwidth consumption - the attacker floods the victim with ICMP
packets, and tries to
consume all possible bandwidth. (Very Common)
Network Connectivity - The attacker tries to connect to the victim in
such a way that
the connection disables a service. An example would be a
connection that never completes, but the service handeling
the connection reserves system resources to
complete a connection,
since the connection never completes, thhose resources are being
consumed.

The examples of an email DoS attack
Email:
-Sending e-mail messages that have attachments with
256-character file names to Netscape and Microsoft mail programs
-Sending to a user of the Pine
e-mail progam a message with a "From" address larger than 256 characters
-A mail server (SMTP/POP etc) can fail if its "mail bombed". This is
the act of sending hundreds and thousands of bogus emails in a very
short amount of time.
