Written Assignment Answer the following in your own words. 1. What is the difference between a. and a. Why does the maximum packet lifetime have to be large enough to ensure that not only the packet but also its acknowledgments have disappeared? TIME-WAIT requires that there must be enough time between closing and resuming a connection for any packets from the previous instance to disappear (Dordal, 20). Before a packet is discarded from memory and another packet is sent out across the network, we must be able to obtain an acknowledgement for that packet. To guarantee that acknowledgments are received, the packets and the acknowledgment's Time to Live (TTL) must be long enough. TTL should be sufficiently large if an ACK is delayed so that we are aware of when to time out and resend the packet. To avoid wasting transmission capacity or transmitting duplicate packets to the receiving end, the maximum packet lifetime must be sufficiently large. …show more content…
What is the difference between a'smart' and a'smart'? Given one potential disadvantage when Nagle's algorithm is used on a badly congested network. By buffering and holding data to send smaller or larger packets, Nagle's method reduces the number of packets we must send. It can cause a major delay for an application in a highly congested network because we are now waiting instead of attempting to send a series of smaller packets as they appear. The application's delay increases if the packet is lost or needs to wait to transmit. Smaller packets would have had a higher chance of transmitting more frequently during periods of heavy congestion, which would have allowed them to serve application data more

...Marthe Francois NURSE4420 Unit 3 Assignment 1 I believe that customer satisfaction is an important aspect of a good quality company. For example, when a client comes to your company and you don’t satisfy the client well enough, he can give you a bad review to his peers and friends. His friends could have a lot of influence and when your company gets bad reviews, you start to lose profit and clients in general. If your clients are very satisfied with you, they can recommend you to their friends and they can give you more customers so that your company or organization can grow economically and socially.

... Active Directory information will be reproduced effectively between the LA and NY logistics. One of the reasons why there will be at least one member of the IT department in New York, is so that the IT department may expand network infrastructure whenever necessary. If there were a lack of IT support on site in New York and GAI had no need for such an expansion, then there would be a possible justification for Server 2012 Read-Only Domain Controllers. Instead there will be a domain controller at each location with writable capability established. The Organizational Units (OU) which constitute domain configuration are as follows: • Executives • Accounts & Sales • IT • Creative Media Production • Human Resources & Finances The privileges for all users accounts, including print servers, network access, and read-write privileges will be established during their Active Directory login creation and OU assignment. These will be modified by system administrators on an ad-hoc basis. Members of the IT OU will maintain the advanced permissions necessary for setup and troubleshooting of Active Directory and OU.

...1 Introduction User's privacy has been an issue of great interest for most people. There is a growing concern over how a user's information can be accessed and used without the user's knowledge nor his consent. On networks this has given rise to privacy control settings on social media to proxy servers to onion routing systems like Tor to ensure that the user has the ability to maintain his privacy online. This concern also extends towards the execution of processes on a user's machine. There is a lot of data of the user's activity that persists on the user's personal system itself for an attacker to take advantage of. A user may want to ensure that any data produced during the execution of any particular application should not be recoverable in any way. Thus it is absolutely critical that privacy concerns must first and foremost be addressed on a user's local system. Research into this area has lead researchers to develop a system call PrivExec[3] that can be used to execute any particular application privately with absolutely no records left behind of it's execution. While this approach may have given user's a solution to their privacy concerns it has at the same time given attackers a tool to cover their tracks. Attackers now have the ability to execute malicious code on systems without...

My fist step in conducting this Penetration testing would be to search for information on this organization because I want to see what information is out there that a hacker might have benefited from. To complete this task I would use the site "Whois.net", the site "Netcraft" and some search engine skills.By searching the organization's domain name in the whois.net interface I can find running name servers and their respective IP addresses. Netcraft, on the other hand, would allow me to gain significant information about the organization such as the type of OS this corporations computer's run, the DNS admin domain name, name server, and IPv6 address if any. Searching for specific information about this organization by utilizing search engine skills can provide me with important information on this organization, such as emails addresses and a more extensive list of IP addresses. This attacker might have compromised the network by sending out phishing attacks to employees emails so I will utilize a tool called "the Harvester which will allow me to catalog email addresses and subdomains related to the organization.

...sent off. Emails would also require authentication of user certificate before being sent from the users account, verified while the CAC card is still inserted within the machine. 2. The security solution that I am recommending impacts the threat by requiring additional authentication that the sender must provide. While it is not full proof it requires that the sender provide more than just a pin number or username and password. These additional steps should provide ample time to identify that the user is not who they claim to be. Most hackers are not prepared for additional security procedures. Although a static defense is prone to more study by those who wish to defeat it, developing a more active and mobile form of defense is preferred. 3. The system that I propose can be easily implemented in a timely manner. In step 1a the procedures are simply a change in desktop procedure, which can be established in a matter of days through re-writing. Step 2a can be completed quickly, at least for the first step.

...It can be quite annoying if the PC is often unresponsive, especially if there is something really important to be done or the user requires instant access to data for someone who is sitting in front of them. The following guidelines could be helpful to make computer faster. Lessen the Number of Applications Installed One of the main causes that slow down the PC is having too many applications installed in it, regardless of the system being used. When games and applications are installed to a computer, some files are stored in the Windows directory structure and a lot of changes happen in the Windows Registry file. Majority of these changes are not promptly obvious to the Windows user. Programs that are redundant repeatedly ask the system to run a maintenance and occupy the hard disk drive, causing Windows to become unacceptably slow to respond. The appropriate removal of these programs needs uninstalling the application by going to the Control Panel – Programs and Features icon. Uninstalling an application or a software instantly after using it can speed up pc. There are also available third party programs that could help to remove applications that don’t have uninstall procedures or don’t completely remove themselves. Stop All Unnecessary Background Processes At the left hand corner of the computer screen, there is a group of small icons called the “system tray” or “notification area.” Every icon corresponds to a program that has been initiated or is just running in the background...
