1 OPERATING SYSTEMS SECURITY CPU & BASIC COMPUTING HARDWARE Homework 01 Addendum I Dr. Bill Mihajlovic NYIT Topics CPU and systems inspection utilities CPU Z utility download CPU Z utility installation CPU utility use for CPU and system bus inspection. System hardware auditing and report generation, (documentation). Windows CLI system auditing commands. CPU microcode alteration 2 1

2 Example: CPU Examination Utility Download utility CPU Z from: 3 Example: CPU Examination Utility Download utility CPU Z from: 4 2

3 Example: CPU Examination Utility Extract from the archive executable utility cpuz.exe. Read file cpuz-readme.txt 5 Example: CPU Examination Utility Simply start cpuz.exe without any installation. Answer the following questions and document your answers with screenshots. 6 3

read: Look for Data width) 7 Question 1.2 Read your cpuz.

4 Question 1.1 Dump your registers in a text file. Present register dump that file and find your CPU bus data width, (Hint read: Look for Data width) 7 Question 1.2 Read your cpuz.txt file and find what instruction sets does your CPU support (can execute, can understand)? (Hint: Look for Data width) 8 4

5 Exercise 1.3 To answer this question go to: What is the purpose of MMX CPU instruction set (Assembly) command CPUID? What was the first CPU capable of executing this instruction? Does cpuz.exe utility use the result of this command? 9 Exercise 1.4 To answer this question go to: Which Intel Pentium CPU has been upgraded by SSE instruction set, (Was not capable of understanding SSE)? When was SSE instruction set extension introduced? What is your processor s CPUID code? 10 5

6 Question 1.5 What is the name of your CPU? Show the screen shot indicating your CPU name. 11 Question 1.6 How large were transistors used to manufacture your CPU in nano meters [nm]? 12 6

7 Question 1.7 Read cpuz.txt and find the following: What is your CPU core internal speed? What is the rated external system bus speed? How many times is internal CPU (core speed) bus speed larger than external system bus speed? 13 Question 1.8 Does your CPU have L1 cache memory inside? If yes, how large is the internal L1 cache memory of your CPU? 14 7

8 Question 1.9 Run your control panel system. 15 Question 1.9 What speed does Windows utility system.exe report? Does it report internal CPU speed or external data bus speed? 16 8

MS Windows XP UI Shells Windows XP provides GUI (Graphical User Interface) shell to all users and super-users or Administrator user (SA, Sys Admin or Systems Administrator).

9 MS Windows XP UI Shells Windows XP provides GUI (Graphical User Interface) shell to all users and super-users or Administrator user (SA, Sys Admin or Systems Administrator). GUI desktop shows icon objects that have list of properties. Some icons represent executable files. 17 MS Windows XP UI Shells Windows XP provides also CLI (Command Line Interface) shell cmd.exe to all users and Administrators. 18 9

10 CLI Shell Commands Start windows CLI cmd.exe shell. (Hint: Start Run cmd.exe 19 CLI Shell Commands Change directory to the root directory and clear your screen. (Hint tupe: cd \ and cls 20 10

11 CLI Shell Commands To start form CLI Control Panel set of programs sub utility system properties type: control sysdm.cpl 21 Question 1.10 Go to the site: Execute all listed control panel tools/utilities from the command prompt and document each with the screen shots shown in the previous slide. Utility Accessibility Options Add new hardware Add/Remove Programs Command control access.cpl control sysdm.cpl add new hardware control appwiz.cpl 22 11

12 CLI Control Panel Utilities Utility Date/Time Properties Display Properties FindFast Fonts Folder Keyboard Properties Mouse Properties Network Properties Password Properties PC Card Command control timedate.cpl control desk.cpl control findfast.cpl control fonts control main.cpl keyboard control main.cpl control netcpl.cpl control password.cpl control main.cpl pc card (PCMCIA) 23 Bus Adapters and Peripheral Lines Input/Output or I/O controller devices have peripheral connectors on one side and system bus connectors on the other side. Since they connect two incompatible sets of lines, peripheral to bus lines, they are also called bus adapter devices or simply adapters

explain their purpose. Where is keyboard device controller located?

13 Question 1.11 Identify all peripheral connectors on your hardware system and explain their purpose. Where is keyboard device controller located? 25 Question 1.12 Identify and itemize all I/O bus slots on your system. What device may be connected via I/O bus slots? 26 13

14 Question 1.13 Go to msdn2.microsoft.com site and find the page on CPU microcode update driver. You should see a page as shown on the next slide Describe what is the purpose of the Intel Microsoft Update driver 27 14

15 Question 1.14 Go to Control Panel System Hardware 29 Question 1.14 Select Device Manager 30 15

16 Question 1.14 Select System Devices 31 Question 1.14 Describe properties of Microcode Update Device
