the interface on the basis of the protocol, IP address, and the port number. The protocol may be TCP, UDP, HTTP, SMTP, or FTP. The IP address under consideration would be both the source and the destination addresses of the nodes. The port numbers would correspond to the well-know port numbers (Vacca, 2009). Packet filtering lets you control data transfer based on the address the data is, the address the data is going to, and the session and application protocols being used to transfer data. The

information system will have a list of new features, which will require personnel to be trained to ensure daily operations are in compliance with future audits. Included in this will be a defined list of network protocol measures, which each employee will be trained. In relation to network protocol will also be security measures, which will serve as the company standard to support compliance for Sarbanes-Oxley requirements. Finally, the newly implemented Fast action response team will need to be knowledgeable

IDNP:Part 2 NTC/362 06/29/2015 Importance of Communication Protocols Communications protocols are a very important communication capability. Communications protocols allow two systems or more to communicate effectively and to pass data over a network and between different communication devices. Communication protocols allows for the process of breaking data down into tiny packets that are the encrypted and signed by the sending device. Each of these packets are sent individually to cut

Communication Protocols Communication is defined as the exchanging of information or news. Protocol, for all intents and purposes, means an official way or agreed upon procedure or standards to accomplish a task. In this case, it would be rules to help transmit data. In networking, there are various protocols needed to make transmission of data easier. In today’s fast paced environment, the standards of information sharing are increasing exponentially. Adhering to the standards are also becoming

but it’s not defined till which period or duration it has to wait is called non deterministic protocol. It can be also defined as the system that has the possibility of multiple output for each input so that the output cannot be predict. Example: CSMA/CD Q2 Answer A timer is set, before the timer runs out, a clear to send (CTS) will be received from the access point. Q3 Answer No, for the 5 Ghz protocol have a small transmission distance approximately 30 meters and this frequency has trouble to

KFF Week 3 Pt 2 Sean Rachubka NTC/362 KFF Week 3 Pt 2 When it comes to communications between devices, there is a requirement in which the devices will agree on the format of the data being used. Communications protocols must adhere to the following; the rate of transmission either in baud or bps. The transmission is to be synchronous or asynchronous. Also, the data is to be transmitted in half-duplex or full-duplex mode. Baud transmission is the number of signaling elements that occur each

What is an IP address? * IP address - a unique identifier assigned to your PC in a network connection * Internet Protocol address is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. Source: Wikipedia a. How do you know your computer’s IP address? * command prompt then ipconfig * if you have a virtual network computing (vnc)

Information Systems Security Professional 2 Professor Laurent Boucard 6/13/18 1) What is a common implementation for the IPSec protocol? The best and commonly used implementation for the IPSec is VPN that uses the Cisco routers to protect the system against risk vulnerabilities. There are four major basic steps applied in utilizing IPSec VPN protocol that ensures the system is same and free from external attacks. The four steps include the encryption of data transmission, validation of

networks and the various devices and computational facilities connected to them. The procedures by which computers communicate with each other are called "protocols." While this infrastructure is steadily evolving to include new capabilities, the protocols initially used by the Internet are called the "TCP/IP" protocols, named after the two protocols that formed the principal basis for Internet operation. On top of this infrastructure is an emerging set of architectural concepts and data structures

architectures efficiency and agility. In some sense, there is a competition going on between these protocols, as they are not directly compatible, and network providers and users are being forced to determine whether to support one or both protocols for various network services. The new version of IP,(i.e. IPv6), constitutes an effort to overcome the inborn limitations of IPv4, in order for the new protocol be able to respond to the new needs as they shape today in the Internet. This paper is aimed
