Networks[1]
Network security consists of the policies and practices adopted to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority.[2]
Methods of network security[edit]
encryption types[edit]
- PSK (pre-shared key)
- WEP (dead)
- WPA / WPA2
userID[edit]
- This method requires a user to present authorized credentials, usually a username and password.
trusted media access control (MAC) addresses[edit]
- This method uses unique MAC addresses of every host to authenticate it to a network resource or network packet switching device.
Advantages and disadvantages of network security[edit]

encryption types[edit]
userID[edit]
Advantages[edit]
- Access rights to the network can be set for each user
- User groups can be created to manage user rights in batches
Disadvantages[edit]
- A userID can be stolen
- system can be bypassed
- Does not protect against intercepting messages in the network
trusted media access control (MAC) addresses[edit]
Standards[edit]
These standards are used from the IB Computer Science Subject Guide[4]
- Describe the different methods of network security.
- Evaluate the advantages and disadvantages of each method of network security.
