Securing Data On A Network, Including The Internet
Muhtasari
Every time data travels across a network it passes through cables, wireless signals, routers, and servers that other people could potentially intercept. The methods used to keep that data safe range from simple passwords to sophisticated encryption algorithms, and choosing the right combination depends on what you are protecting and who you are protecting it from.
In this lesson you will explore seven layers of network security: authentication, firewalls, encryption (including WEP, WPA, and public key cryptography), VPNs, file access rights, transaction logs, and backup strategies. You will learn how to match each method to a real scenario, a skill that Edexcel tests in both Paper 1 and Paper 2.
Malengo
- Know about and understand the use of log-ins and passwords, firewalls, WEP/WPA, encryption, VPN, file access rights, transaction logs and backups
- Be able to select suitable methods of securing data for a particular context
