Chapter 8, Problem 17MLM
Program Plan Intro
System vulnerability:
- When huge data amounts are been kept in electronic form, it becomes susceptible to many threats.
- The
information systems in many locations are been interconnected through communication networks. - The unauthorized access can occur at many access points in network and is not limited to single location.
- The data flowing over networks could be accessed; valuable information could be stolen while transmission or data could be altered without authorization.
- The denial-of-service attacks are launched by intruders to disrupt website operations.
- Internets are vulnerable than internal networks as it is open to everyone.
Spoofing:
- It denotes a scam type where an intruder tries to achieve unauthorized access to system.
- The purpose is to gain sensitive information form the user.
- It includes bank account details, personal data such as passwords.
- It denotes a type of forgery with modern technology.
