...configure, maintain and monitor rules for multiple profiles, notifications and authenticated exceptions and he would also like me to be able to create and manage inbound and outbound rules and with windows firewall I can accomplish both of these task because Windows Firewall with Advanced Security works by examining the source and destination addresses, source and destination ports, and protocol numbers of a packet, and then comparing them to the rules that are defined by the administrator. When a rule matches a network packet then the action specified in the rule (to allow or block the packet) is taken. Windows Firewall with Advanced Security also lets you allow or block network packets based on whether they are protected by IPsec authentication or encryption. Then I could also have capabilities of Data encryption and connection security rules with Windows Firewall Data protection includes both data integrity and data encryption. Data integrity uses message hashes to ensure that information is not being changed while in transit. Hash message authentication codes (HMAC) sign packets to verify that the information received is exactly the same as the information sent. This is called integrity and it is critical when data is exchanged over unsecured...

...for a change in the way data is delivered. Currently it’s by one packet of information (data) at a time. After some research I have learned there are a number of ways people are trying to change this method of data delivery. Some of them are: • Packets • Capsules • Holograms and Lasers • Teleportation I will give a brief explanation of each one and include the advantages and disadvantages. The current technology uses packets which are small files of information wrapped by a header and footer with security information on the both sides. These are the destination the packets are being sent to and the source that the packets are coming from. The advantages are: Packets are very secure because they can use encryption. Key exchange algorithms are used to securely exchange a shared secret value between two computers over an unsecured network connection. The computers exchange information that, when processed by the algorithm, produces the shared secret value. A third computer listening on the network and intercepting network packets between the first two computers cannot determine the shared secret value. The shared secret value can then be used as a session key, or to generate a session key, to encrypt the rest of the communications used in the IPsec negotiations. (Technet) • Small enough to send quickly The disadvantages are: • high learning curve • only sent one packet at a time Bottom line with packets it is like downloading a two-hour movie in 3 hours with a Fast-Ethernet...

...William Kollie IS3120: Convergence of IP Based Network MR. McMiller July 20 2014 The dial up connection is made from a computer through modem and telephone line to the ISP's computer. The computer uses data in digital form. It means that it the computer can transmit data in 1's and 0's on and off also called digital or binary form. On other hand, telephone lines transmit data in analog form. It means that they transmit data by sound. the telephone line from your house is joined to a special terminal that sends the data received from their computers in form of audio signals from to enter the Public Switched Telephone Network PSTN. From PSTN, it is routed to the person or ISP that the modem is calling through the internet. Dial-up connection face connectivity problem which the user has to deal with. Dial up connection is unstable, dialup demand phone line connection which block incoming calls access, the chief disadvantage of dialup Internet, as compared with broadband Internet, is its slowness. Access to modern broadband networks is essential in the information age, said FCC Chairman Tom Wheeler. Yet 15 million Americans live in areas where they can’t get wireline broadband no matter how much they want it. These funds will jump-start broadband access in areas that would otherwise be bypassed by the digital economy. At least 100 million U.S. homes should have affordable access to actual download speeds of at least 100 megabits per second and actual upload speeds...

It has a very very short range and is unable to penetrate walls and other objects. 3. It is able to maintain connection anywhere in the house it is setup in without the need of trailing a connection cable like wired connections so you get a tradeoff of speed vs versatility Lab 6.2 Review 1. The biggest problem would be collision if multiple routers are using the same channel a common example of this is Comcast routers are set to use a channel close to the signal for the ps3 so you get a depredation of signal and loss of data packets as the connection goes on. 2. If a previously stated standard is not compatible with your adapter you could have issues with your connection not connecting Lab 6.3 Review 1. Um well I could write a book but simply a guest having access to your network could result in any imaginable results on your network to name a few rootkits,Trojan droppers, Remote Access Terminals, Keyloggers, Viruse’s. 2. Setting a MAC filter is a good way to filter who has access to your network its simply like saying Fred has access to the building with his fingerprint being scanned by a biometric scanner. Although this can be spoofed by spoofing your mac but you would still have to find out which macs are allowed and have to make sure the mac your spoofing is not connected so that you do not receive a duplicate error.

IP routing defines exactly how routers makes their choices of how to forward data in a TCP/IP network. : frame and packet. The term frame specifically refers to encapsulated data that includes the data-link header and trailer, plus everything in between—including the IP header.
