ISC2 SSCP Exam - Topic 6 Question 100 Discussion
Topic #: 6
What is the most critical characteristic of a biometric identifying system?
AH provides integrity, authentication, and non-repudiation. AH does not provide encryption which means that NO confidentiality is in place if only AH is being used. You must make use of the Encasulating Security Payload if you wish to get confidentiality.
IPSec uses two basic security protocols: Authentication Header (AH) and Encapsulation Security Payload.
AH is the authenticating protocol and the ESP is the authenticating and encrypting protocol that uses cryptographic mechanisms to provide source authentication, confidentiality and message integrity.
The modes of IPSEC, the protocols that have to be used are all negotiated using Security Association. Security Associations (SAs) can be combined into bundles to provide authentication, confidentialility and layered communication.
