Network Attack server with traffic to overwhelm it, causing a disruption in service. These attacks can 
be devastating for businesses.
Patterns
4. Man-in-the-Middle Attacks: In these attacks, an adversary intercepts 
communication between two parties without their knowledge. This allows them to 
eavesdrop or manipulate the information being exchanged.
5. Brute Force Attacks: Cybercriminals use brute force attacks to gain access to 
systems by systematically trying every possible combination until they find the 
correct password or key.
Network Security  The Importance of Network Security
Attacks: With the increasing frequency and sophistication of network attacks,
