What three (3) are major concerns when sending private data over a public medium?

A.
Integrity

B.
Authority

C.
Capacity

D.
Confidentiality

E.
Authentication

Explanation:

Authentication-Authentication ensures that digital data transmissions are delivered to the intended receiver. Authentication also assures the receiver of the integrity of the message and its source (where or whom it came from). The simplest form of authentication requires a user name and password to gain access to a particular account. Authentication protocols can also be based on encryption, such as DES or 3DES, or on public-key systems using digital signatures. Integrity- While it is important that your data is encrypted over a public network, it is just as important to verify that it hasn’t been changed while in transit. For example,IPSechas a mechanism to ensure that the encrypted portion of the packet, or the entire header and data portion of the packet, has not been tampered with. If tampering is detected, the packet is dropped. Data integrity can also involve authenticating the remote peer. Confidentiality- This is perhaps the most important service provided by any VPN implementation. Since your private data is traveling over a public network, data confidentiality is vital and can be attained by encrypting the data. This is the process of taking all the data that one computer is sending to another and encoding it into a form that only the other computer will be able to decode.
