5 CSLOs 1 Assessment: Written Report Description: Students will show proficiency in locating information about threats to the operating system of interest to them and applying judgment in whether or not to apply the recommended remedies to the operating system of their choice. They have the freedom to select a threat to Microsoft Windows, UNIX, Linux, or Android operating system. Optionally, they may choose a mainframe operating system such as IBM zos/390 or the Tandem Guardian. Rationale: There is increasing evidence cyber threats will be ever more sophisticated, present, and effective due to the variety of sources they emanate from which range from individual actors to state sponsored cyber warfare. An educated computer professional must be able to speak to this presence and also how to keep up-to-date on current events and countermeasures to very real events. A sample report follows: Student locates a threat on the Computer Emergency Response Team (CERT) site and completely articulates all dimensions of the threat. They include the actual numerical metric (0-180) provided by CERT, its complete potential impact (summarized from the article on CERT), all systems/applications affected (including operating systems other than the one of interest), and the actions they would take to mitigate the threat. The actions that would be taken would have additional elements beyond meets proficiency such as notifying users of the vulnerable operating system and what is expected of them to mitigate their part of the threat through their own behaviors and vigilance, setting up scripts to capture any detection/evidence of the threat in system logs along with alarms, especially searching for evidence that the threat already exists on their system(s), and a good judgment of whether to apply the fix. CSLOs 2 Assessment: Laboratory Exercise Description: Students will show the ability to measure network performance and make appropriate recommendations for improvements or optimizations. Rationale: Networks are complex structures and context sensitive. Network administrators are often faced with facilities having multiple datacenters or local office sites which contain differing systems, equipment, and protocols. Network administrators are expected to understand how parameters and settings in both hardware and software affect performance. With this knowledge, they can avoid incorrectly altering a configuration. Conversely they will be prepared to investigate whether a configuration is within acceptable operating limits and correct it if necessary. A sample lab report follows: Networked Host 1: Networked Host 2: Transmission File: Network OS: Location Network MTU Network OS: Location Network MTU Name: Type: Size: Transmission 1 Standard MTU: Host 1 MTU setting Host 2 MTU setting Total Transmission Time: Transmission Rate: Transmission 2 Minimum MTU: Host 1 MTU setting Host 2 MTU setting Page 5 of 11

6 Total Transmission Time: Transmission Rate: Transmission 3 Maximum MTU: Host 1 MTU setting Host 2 MTU setting Total Transmission Time: Transmission Rate: Observations on the effect of packet size (MTU) on effective transmission rate: Recommendations on adjusting the MTU setting of cooperative hosts if they are exchanging large files: CSLOs 3 Assessment: Textbook Assignment Description: Students will be asked to how they should upgrade and patch a specified operating system.. Because it is easy to install every upgrade and patch available for the type of computer in question, the assignment will ask the student to explain why they should not do this. Rationale: The ability to upgrade and patch an operating system in a selective manner is central to a computer professional s competence in maintaining the viability and ongoing function of the systems they are in charge of. In order to select the correct and most beneficial additions to their operating system using an established range of criteria, they also demonstrate an understanding and competency of that operating system as well. A sample project follows: "Taken as a whole, computer software in both the operating systems and applications of a computer is very extensive and complex with potentially thousands of interfacing points and states. Potentially dozens of patches or fixes for this software are made available daily in the world of computing which comprises all the manufactures of operating systems and the hundreds of applications in existence today. Give a compelling argument AGAINST *automatically* installing or applying all these patches and fixes to your system, even if they relate to your computer's software. " CSLOs 4 Assessment: Quizzes Description: Students will complete chapter quizzes which will reinforce concepts learned during assigned readings. Rationale: The textbook relates the theory in the text to the implementation and operation of that theory in the course labs and chapter assignments. Chapter quizzes serve to reinforce the theory by asking the student to differentiate between correct, partially correct, and incorrect answers to questions pertinent to the topic. Page 6 of 11

Answer 1. generates an operating system error 2. is truncated 3. is broken up and stored in more than one field. 4. combines multiple fields to accommodate the data Method of Evaluation/Grading: CSLO 1: Identify, assess, and explain how an operating system can be configured to prevent common security threats. (Networking and Security #1 & #2, Computer Support Specialist #1) A level student work will incorporate: Page 7 of 11

8 Identify a current or recent complex threat. Identify multiple operating system or application software affected by the threat and how the threat is propagated. Rate the cruciality of the threat in terms of its attack on core function or peripheral function on a scale of 1-5. Assess the potential impact of the threat on the three major dimensions of likelihood of occurrence, impact, and ability to detect its presence. Suggest three or more effective solutions in terms of prevention or, in the case of the threat s already occurring, mitigation after the fact. C level student work will incorporate: Identify a recent simple or moderately complex threat. Identify at least one operating system or application affected by the threat. Indicate whether threat is an attack on core function or peripheral function. Assess the potential impact of the threat in one or two dimensions of impact, likelihood of occurrence, and ability to detect its presence. Suggest at least one effective solution in terms of prevention or mitigation after the fact. CSLO 2: Perform a laboratory exercise to measure the effect of packet size on the throughput rate of network transmissions between two hosts on different networks. (Networking and Security #1 & #2, Computer Support Specialist #1) A level student work will incorporate: Discovery of the PATH MTU by using Path MTU Discovery and setting the DF (do not fragment) flag within the TCP/IP software on the sending host. The receiving host s MTU will have been set at the IPV4 maximum of 1500 bytes by the instructor. Transmission a ten gigabyte file between the sending and receiving machines. During this time, the student will measure the effective throughput rate and total transmission time of the file at the 1500 byte MTU. Adjustment of the packet size on the sending host to 9000 bytes and transmit a second ten gigabyte file to the receiving host. The effect of sending jumbo packets and the subsequent fragmenting of the packets down to the 1500 byte MTU will be noted by the student in their results. Adjustment the packet size on the sending host to the 576 byte minimum specified by the IPV4 protocol. They will send a third 10 gigabyte file and note the effect of minimum packet size on total transmission time. Ability to specify the payloads of each MTU and the overhead (additional time incurred) in processing and reassembling the fragmented packets. Ability to state why using a minimum packet size greatly increases processing overhead of PDU (protocol data unit) headers. C level student work will incorporate: Identification the TCP/IP software on the transmitting and receiving hosts from two different networks and note the packet size setting in each host. Transmission a ten gigabyte file between the sending and receiving machines. During this time, the student will measure the effective throughput rate and total transmission time of the file at the maximum IPV byte MTU. Ability to state in qualitative terms what effect usage of jumbo or minimum packet size will have on transmission efficiency between two networks. CSLO 3: Demonstrate operating system knowledge by upgrading and/or troubleshooting common problems related to an operating system. (Computer Support Specialist #1 & #3, Microcomputer Systems Specialist #1 & #2) A level student work will incorporate: Give compelling argument, listing at least five reasons, why a system administrator should not apply all available patches (fixes to problems) to an operating system. Given a specific scenario, the student will find, select, and apply the relevant patches to the operating system. Page 8 of 11

9 Specify how a system administrator may mitigate the impact, if any, of applying the selected patches. Discuss how the system administrator would advise the users of computer systems of the impact of the new patches in terms of system performance as well as conversion of current software or associated files to new formats or function. This would include new, altered, or deleted function as well as look and feel of any interface. C level student work will incorporate: Give at least two good reasons why a system administrator should not apply all available patches (fixes to problems) to an operating system. Describe the steps taken to locate, select, and apply patches for a given operating system. List possible at least two possible impacts of applying patches to computer systems. Indicate that the system administrator should make available a list of patches and affected software to the user community. CSLO 4: Effectively utilize the features and capabilities of an operating system, including file management, backup, and user interface customization. (Computer Support Specialist #1, Microcomputer Systems Specialist #1) A level student work will incorporate: Describe how primary storage differs from secondary storage and give examples of each type. Explain the difference between buffering and blocking and indicate the advantages of each. Compute the actual number of blocks and tracks a file will require in order to be stored on a disk, Given a specific scenario, select a strategy for the frequency of a file or disk backup and which type of media (external disk, flash drive, network store, etc.) might be used for such a backup. Provide advice for a data systems manager on how they might obtain compliance from their staff on initiating and maintaining timely and effective backups. Demonstrate how the user interface in a Windows operating system can be customized to the needs of the user so their files can be backed up and managed automatically. Page 9 of 11 C level student work will incorporate: Describe how primary storage differs from secondary storage. Explain the difference between buffering and blocking. State how many whole blocks can fit within a track of a given size. Describe one strategy for the timing and type of file backups.
