Chapter 20 Security Practices
20-2 Download and Use AV Software
I downloaded the AVG Anti-Virus software. I performed a scan and found no suspicious programs. I completed an update and scheduled the utility to run a scan every day at 4 AM.

20-3 Researching Running Processes
When comparing the running processes between a normal boot, and starting in safe mode, normal has 96 processes and safe mode has 19. Rather than listing all of the differences, I have posted screen shots below.
The following are some of those processes and a description of each:
Apoint.exe- Part of the driver for the touchpad on my laptop.
avgam.exe- Process for AVG Anti-Virus software.
ccApp.exe- Is responsible for checking emails and auto-protect facilities as a part of Norton Anti-Virus.
hidfind.exe- Is associated with Alps Pointing Device Driver and is critical to stable PC performance.
issch.exe- Is an update service for Install Shield.
lsass.exe- Serves as Local Security Authentication Server for Microsoft. It is responsible for enforcing the security policy within the OS.
MDM.exe- The debugging system for Internet Explorer.
quickset.exe- process in Dell computers that allows you to access power management diagnostics and settings.
stacsv.exe- C-Major Audio Service from SigmaTel Inc.
winampa.exe- Utility for listening to audio or watching video.
Chapter 19 Security Essentials
19-3 Using a Port Scanner
In class we downloaded Advanced Port Scanner by Famatech. Then we created a LAN using a switch. Using the port scanner we were able to see wich ports were open on everyone's computers. If the Windows firewall was up, that coputer would not show on the port scanner.

19-4 Managing User Accounts
From a standard account without administrator privelages it will not let me view the documents folder of an administrator account.
When trying to download a program or create a new account from a non-admin account, Windows asks for you to imput an Administrator Password.
RP 19-2 Recovering from a Forgotten Windows Password
I researched three different password recovery utilities.
1-Ophcrack uses rainbow tables to crack passwords, and has an easy to use GUI.
2-Password Changer allows you to reset the password or log in using a blank password, and also has a GUI. $49.95
3-ResetWindowsPassword.com has you boot from a CD or USB which contains the program, and resets the local password for you. $29.95.
I would use Ophcrack, simply because it is free.
Chapter 18 Networking Practices
Today in class we set up a wireless network and a switched network and attempted to share files.
Using the switch network was simple. Everyone just pluged into the switch and had to allow files to be shared.

Setting up the wireless network was a little more complicated since we configured the DHCP server, but the router manufacturer's web site made it pretty simple to imput the information and it did the rest of the work.

17-1 Investigating Your PC
1) I use a wireless connection on my computer.
Windows sees it as: Intel(R) PRO/Wireless 3945ABG Network Connection.
2) My MAC adress is 00-1C-BF-64-FD-AB
3) My IP adress is 192.168.1.6
4) I used the TCP/IP utility to answer these questions by opening a comand window and entering ipconfig /all.

17-3 Researching Switches
1) There were very few switches that I could find with low number of ports. All that I found were made by Cisco, so I had to go up in size a little. Below is a snip of the comparison page...
2) Before making your decision you would want to know what purpose the switch will serve. In this case with a small business you dont need top of the line, you should look more at dependability and economy. I would chose to go with the one from Cisco. They are a well known company, it carries a lifetime waranty, and it is the cheapest out of the three switches with very similar features. The one drawback is the RAM and ROM size are fairly small, but with only 4 computers connected, that shouldnt be a problem.
3) All three NIC that I chose are virtually identical. I went with lower end adapters for save money since high speed gaming applications are not a concern.
4) Even though it is $10 more, I would recomend going with the Intel adapter simply for brand recognition. I am more familiar with their products and therefore feel more comfortable recomending them.
5) This upgrade, including one switch and 4 network adapters would cost $604.95 plus labor.
