This diploma course introduces you to the architecture and protocols used in network security. We explain the structure and function of local area networks (LANs) and wide area networks (WANs) and examine key devices like hubs, switches and routers. These allow for efficient communication through a network and this course teaches you everything you need to know to keep that data safe from prying eyes, an invaluable skill in the Information Age.
Alison was founded in Galway, Ireland, in 2007 and has grown organically to become a major force in free online education and skills training. Today, with more than 30 million learners in 195 countries, Alison is changing how the world learns and up-skills.
We are committed to equality and access to education and skills training irrespective of gender, geography, economic status or any other barriers that can so often stunt potential. So we offer a range of free courses that meet the many diverse needs of our learners. The UN declared in Article 26 of the 1946 Declaration of Human Rights that “Education shall be free…”. This statement will always inspire us.
Alison was founded by Alison CEO, Mike Feerick. Mike is a businessman, but one with a difference. He believes in social impact, and that you can build a financially successful business focused on meeting a huge global social need, making education and skills training more accessible for everyone. He invites anyone who believes that too, to support the Alison mission.
Alison is free of charge to you. But it’s still a business – albeit a socially-focused one. We are a social enterprise making our money through advertising, merchandise, and the sale of Certificates and Diplomas, should a graduate choose to buy one.
