Network Security:
For Unit 2, Outcome 2, you are required to describe the functions and capabilities of different types of networks
An overview of networks, with an emphasis on network security in a global environment. An explanation of networks, key network hardware and software components and communication methods is given. A range of security threats to data and information are discussed, in addition to a range of security measures that can be used to protect data and information from these security threats. The interactions and impacts created by networks are also discussed, with a focus on legal and ethical considerations required by organisations that operate in a global environment. For this outcome you will be required to design a Local Area Network (LAN), describe its components and methods used to communicate data and information. A range of security threats and strategies to protect data and information from these threats also need investigation.
