Malware Types and Cyber Attack Defense Strategies
Malware: Malicious Software Defined
Malware is malicious software designed to disrupt systems, steal information, or gain unauthorized access. The primary goals of malware include:
- Disruption: Shutting down processes or freezing systems.
- Data Theft: Exfiltrating sensitive data like passwords.
- Unauthorized Access: Providing attackers with a secret entry point.
- Covert Control: Enabling remote command and control (C&C) operations, often forming botnets.

a) Disadvantages of Virtualization
(Any 3 points for 2 marks)
Performance Overhead:
Virtual machines run on top of a hypervisor, so applications may not perform as fast as on physical hardware.High Initial Cost:
Powerful servers, hypervisors, and storage systems are required, which increases setup cost.Complex Management:
Managing multiple VMs, snapshots, networks,
