Importance of cyber security
• The importance of cyber security comes down to the desire to keep information, 
data, and devices private and safe.

Distributed denial-of-service (DDoS)
• Distributed denial-of-service (DDoS) attacks are those in which multiple systems disrupt the 
traffic of a targeted system, such as a server, website or other network resource. By flooding 
the target with messages, connection requests or packets, the attackers can slow the system 
or crash it, preventing legitimate traffic from using it.

Advanced persistent threats (APTs)
• Advanced persistent threats (APTs) are prolonged targeted attacks in which an attacker 
infiltrates a network and remains undetected for long periods of time with the aim to steal 
data.
