Which of the following best explains how RADIUS and TACACS+ differ? TACACS+ utilizes UDP whereas RADIUS uses TCP. The Cisco Secure ACS software supports RADIUS but not TACACS+. RADIUS encrypts all communication, whereas TACACS+ simply encrypts the password. RADIUS integrates authentication and authorisation into a single procedure, while TACACS+ separates them.

For instance, we studied how a dual-factor authentication works when a password generator is used: S → U : N U → P : N,PIN P → U : {N,PIN}x U → S: {N,PIN}K Can you modify the set of rules outlined above to describe the protocol of dual-factor authentication when a mobile device is involved? please submit 1. a high-level overview of how the protocol would work 2. the description of the protocol using the formal notation

Why is it necessary for both computers to send UDP packets to each other in the first place for the firewalls on both sides to permit traffic in both directions?  Why can’t Alice start sending UDP packets to Bob first, and then Bob reply to those packets? Explain in details with diagrams and detailed explanation.

Using a MAC (message authentication code), what happens if an attacker attempts to tamper with the Tag (the MAC) and the ciphertext while in transit? The recipient would be able to spot a tampered Tag/ciphertext, thus please explain why this attack is futile.

Explanation of how to implement native authentication and authorization services for gaining access to protected web server resources. Which of the following provides support for layered protocols? Provide concrete examples to support your assertions.

Say an eavesdropper on a wired network sniffs packets that are part of a TLS-encrypted HTTP session. No other encryption is added. State whether the eavesdropper will see each of the following elements as encrypted or in plaintext: 1) application data, 2) HTTP headers, 3) Layer 4 headers, 4) Layer 3 headers, 5) Layer 2 headers. Justify your answer.

5, For the first mode of  Message Authentication code (MAC), which description is NOT correct?  The key used in this mode is for message encryption. This mode cannot protect message confidentiality. The receiver is able to detect malicious message modification by checking the MAC. The attacker who does not know the key cannot calculate the MAC.

When a web client requests access to protected resources on a web server, show how to build native authentication and authorisation services. Which two reasons promote multilayer protocols? Be specific in your examples.

Question 12 kana.Two remote sites are connected via IPSEC. If Encapsulated Security Payload (ESP) is set to NULL, what fact can be inferred about the connection?The data will be encrypted with a symmetric key rather than the sender's private key.The data is authenticated and encrypted according to the recipient's configured settings.The data may be authenticated but is not encrypted using IPSEC.The data is encrypted at the network layer but not at the application layer.  Full explain this question and text typing work only     We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line

There is a possibility that end-to-end encryption will be an issue with application-level proxies. Give some thought to how an application-level proxy may deal with encrypted payloads and offer some solutions.
