NT 1230 Client Server Networking Unit 2 Assignment 1 Disk Redundancy Research Unit 2 Assignment 1 Disk Redundancy Research 1. What does RAID stand for? Redundant array of independent disks 2. When would you use RAID? RAID’s are useful in large file servers, transaction of application servers, where data accessibility is critical, and fault tolerance is required.
NT2640 Unit 2 Assignment 1 1. What organization has been given the responsibility for assigning protocol numbers? * Internet Assigned Numbers Authority (IANA) 2. Determine the protocol numbers for the protocol names: Protocol | Number | IPv4 | 4 | IPv6 | 41 | TCP | 6 | UDP | 17 | ICMP | 1 | VRRP | 112 | IPSEC ESP | 50 | L2TP | 115 | OSPF | 89 | EIGRP | 88 | 3. Determine the correct ICMP type based on the description provided: ICMP Message Description | Type | Code | Echo | 8 | | Echo Reply | 0 | | Time Exceeded | 11 | | Port Unreachable | 3 | 3 | Fragmentation Needed | 3 | 4 | 4.

The combination of public and secret key technology to secure access to websites is how this protocol works. Microsoft NTLM is an authentication that Windows NT servers use for clients to be authenticated to an NT domain (Shinder, 2014). PAP and SPAP are similar, but SPAP is the upgraded version of PAP, and they are used for remote access control authentication. It is recommended that PAP only be used if there is a compatibility issue as PAP transmits user passwords across the network to authenticate which can be captured by unauthorized users. SPAP encrypts the password and then sends it and the username across the network (Shinder, 2014).
(TCO E) Your organization has decided to host a web server that will be accessible by the public. Organizational leadership is concerned about the web server being compromised and thus allowing the remaining network to be compromised. You want to come up with a solution to host the secure the web server internally, but still protect your network. What should you do? 4.
ISE201 Chapter 8 Homework Key Terms User Account Control (UAC) – primarily a set of policies to reduce the exposure and attack surface of windows by requiring that all users run in standard user mode unless it is necessary to do otherwise. Principle of least privilege – requires each subject in a system be granted the most restrictive set of privileges needed for the performance of authorized tasks Consent User Interface (Consent UI) – used in reference to user account control. The collection of user interfaces that requests elevation form users to complete tasks Secure Desktop – part of UAC. A desktop that windows uses to alter the user interface to protect against malware fooling users into selecting and option that they do not
CIS 109 Week 1 Discussion An Overview of Information Systems and a Computer System 01-06-2015 Strayer University Professor Raza Read the article titled “Top 10 Reasons Why Systems Projects Fail”, located at in the online course shell. You may also view the article at http://dulcian.com/articles/dorsey_top10reasonssystemsprojectsfail.pdf Next, compare and contrast the key differences between information systems and information technologies. Discuss one to two (1-2) ways in which a company uses management information systems in order to increase organizational efficiency and productivity. Explain the overall manner in which the four (4) building blocks (i.e., input devices, CPU, main memory, and output devices) of a computer
Week 6 iLab Report DeVry University NETW360: Wireless Technologies and Services Evaluate and Solve Common Security-Related Problems Submitted to: Professor Richardson Evaluate and Solve Common Security-Related Problems Introduction Overextension of wireless signals is a problem that is faced by any company that chooses to have a WLAN. The problem with a WLAN extending beyond the necessary area, is the availability that is presented to unauthorized users of the network. This report tries to establish the causes of that overextension. And it will also cover how to properly regulate the wireless signal so that the excess signal is reduced. Specific questions from iLab Scenario 1 Discuss how changing the type of antennas affects the amount of signal spilling outside the building?
Refer to the exhibit. A router learns a route to the 192.168.6.0 network, as shown in the output of the show ip rip database command. However, upon running the show ip route command, the network administrator sees that the router has installed a different route to the 192.168.6.0 network learned via EIGRP. What could be the reason for the missing RIP route? Compared to RIP, EIGRP has a lower administrative distance.
