Quizplus · Accepted Answer

Melissa installed a firewall, which checks all incoming and outgoing traffic and only allows authorized traffic to pass through. A botnet is a network of compromised computers used to carry out attacks, while an IPS (Intrusion Prevention System) is a more advanced tool that can detect and block suspicious network activity. Encryption algorithms are used to secure data transmission and storage, but do not provide the same level of network security as a firewall.
