Nt1330 Unit 3 Assignment 1 Questions And Answers

Q1: Briefly explain designing requirements that’s are required when designing the hardware and software infrastructure:

EAP was originally created as an extension to PPP to allow for the development of arbitrary network access authentication methods. With PPP authentication protocols such as Challenge Handshake Authentication Protocol (CHAP), Microsoft Challenge Handshake Authentication Protocol (MS-CHAP), and MS-CHAP version 2 (MS-CHAP v2), a specific authentication mechanism is chosen during the link establishment phase. During the authentication phase, the negotiated authentication protocol allows the exchange of information about the credentials of the connecting client. The authentication protocol is a fixed series of messages sent in a specific order.

Riordan will utilize common protocols including File Transfer Protocol (FTP), Transfer Control Protocol/IP (TCP/IP), User Datagram Protocol (UDP), Hypertext Transfer Protocol (HTTP), Post Office Protocol (POP3), Internet Message Access Protocol (IMAP), Simple Mail Transfer Protocol (SMTP). In any network design the choice of communication protocols dictates the types of computers used and other network processors. Majorly TCP/IP has replaced old protocols such as IPX/SPX and NetBEUI which are obsolete.

User authentication is done at the request router. It takes care of routing the user requests to specific application

Secure Sockets Layer (SSL) is one of protocol of authentication methods.SSL uses a cryptographic system that uses two keys to encrypt data ,a public key known to everyone and a

It provides failed logon attempt thresholds and lockouts which protects against an intruder using brute force to obtain an authentic user ID and password combination.

Q1: Briefly explain designing requirements that’s are required when designing the hardware and software infrastructure:

Briefly explain following designing requirements that are required when designing the Hardware and Software infrastructure:

Introduction: In general authentication is often termed as a process of verification of an individual/user with a server by claiming his/her user entity is true by means of username, passwords etc. Through this process the server determines that the client or user has permission to use a resource or for communication. Authentication is a complete necessary process for the user to establish a communication networking link between user and the server. The process of authentication or login process features an individual in the submission of his username which the user knows commonly enabled through SSL systems, the server checks whether the username is correct or not if it is correct the user is asked to type

SIP and H323 are two known signalling protocol. SIP was founded by Internet Engineering Task Force (IETF) while H323 was created by International Telecommunication Union (ITU). However, SIP is the most one used because it is simple to implement and easy to connected. Due to its simple implementation and high popularity, SIP is becoming attractive target for many different attackers.

some examples of these protocols are POP3 which is short for Post Office Protocol 3 or another internet protocol like IMAP short for internet Message Access Protocol.

Windows authentications are assigned to the users’ account which makes the system more secure. Role Based Access Control (RBAC) is used to control the access of data by different roles of users. For example: an engineer cannot edit a particular job Technique after logging into the system, although an administrator has the ability to CRUD (create, read, update and delete) any job Technique in the system.

A protocol is most simply defined as a standard. These standards define how computers are able to communicate with each other. These standards are defined in documents called Request for Comments( RFC ) which is a formal document from an organization known as the Internet Engineering Task Force( IETF ). These documents are made publicly available so that any program that needs to use these protocols are able to configure them properly so that it works with all other programs that make use of the same protocol. There are thousands of protocols that exist and many of them are very common and others are very seldom used. Some of the most common protocols are HTTP/HTTPS, FTP, SMTP, IMAP, POP3, SSH and DNS. Many of these are used almost every

In the above statement, we create a stored procedure called CheckUser, accountable for authentication of username and password. Here the attacker simply injects ‘’; -- in the query thereby bypassing the authentication through the stored procedure.

Login procedure: Once the registration is complete, the particular user can get a chance to login into the system to access the contents. For this, the user needs to input details for authenticating by entering his/her respective username and password correctly if the values match with the registered one it will validate and go to map where second level of authentication done by location selection along with annotation
