DOS and DDOS Attacks

The video tutorial explains DOS and DDoS attacks, highlighting their impact on network services. DOS attacks involve overwhelming traffic or malformed packets, causing slowdowns or crashes. These attacks pose significant risks due to their simplicity. DDoS attacks, a more complex form, involve multiple sources and use botnets to execute coordinated attacks.

What is a common method used in DOS attacks to disrupt network services?

• Sending a small amount of data at a slow rate

• Overwhelming the network with excessive traffic

• Encrypting all data packets

• Blocking all incoming connections

Why are DOS attacks considered a major risk?

• They only affect outdated systems

• They are impossible to detect

• They can easily interrupt communications and cause financial losses

• They require highly skilled attackers

What distinguishes a DDoS attack from a DOS attack?

• DDoS attacks are less harmful

• DDoS attacks originate from multiple coordinated sources

• DDoS attacks are easier to prevent

• DDoS attacks use a single source

In a DDoS attack, what is the role of 'zombies'?

• They are security software

• They are backup servers

• They are infected hosts used to carry out the attack

• They protect the network from attacks

How do attackers prepare for a DDoS attack?

• By encrypting all data packets

• By using a single powerful computer

• By disabling all network firewalls

• By building a network of infected hosts called botnets
