Join Lisa Bock for an in-depth discussion in this video Providing confidentiality, integrity authentication, and non-repudiation, part of Learning Cryptography and Network Security.
- Network administrators have a lot of responsibility…in order to keep networks up and operational.…However for a secure network environment,…five main services are required.…These services are defined in Requests For Comment 2828…which is an internet security glossary.…I'm already looking at Requests for Comments 2828…but you can easily find it through Google.…We're going to page 154 and specifically look…for Security Service.…
At this point here we actually can see…a definition of security service.…Security service basically outlines a definition…of providing adequate security of systems…or data transfers.…The five services are,…confidentiality, integrity, accountability…and nonrepudiation and authentication.…Now a security service is implemented…by a security mechanism such as hashing,…message digest, digital certificates, and encryption.…
You might not be familiar with these terms,…but we'll go over them as the course progresses.…Now lets take a look at the five services…and what we can provide.…Confidentiality.…
