Implementing Information Systems

A SWOT analysis aids in strategically examining a company's strengths, weaknesses, opportunities, and threats.

S-Strengths
W-Weaknesses
O-Opportunities
T-Threats

This can be applied to an IT department to identify human, technical, and financial resources.

If you see the need for a systems request or someone else mentions they need IT support, it is probably for one or more of the following reasons:

• better performance
  
• improved services
  
• reduced cost
  
• more information
  
• stronger controls
• support for new products and services

When you decide you want to implement a new information system consider these internal factors:

• Strategic Plan
• Top Managers
• User Requests
• Information Technology Department
• Existing Systems and Data

Also consider these external factors:

• Technology
• Suppliers
• Customers
• Competitors
• The Economy
• Government
  

Snort Install Round One: no C compiler (gcc)

I downloaded Snort from http://www.snort.org/downloads. I downloaded the 2.8.4.1 version.
This site http://www.securityfocus.com/infocus/1421 has the instructions to install Snort. This is where I got the instructions to install 'libpcap'.
It also has instuctions on trouble shooting and understanding SNORT
I downloaded libpcap-0.8.1 from http://sourceforge.net/projects/libpcap/.
As I read the Install.txt file I found how to use the command console to install libpcap.

I entered the following into the console
su ---to bring up the root
usergzip -d -c libpcap-0.8.1.tar.gz tar xvf - ---then all the files were listed inside
cd libpcap-0.8.1/ ---going into the folder now
./configure ---and then it configured the setting of computers settings as well it checked the C compiler (gcc ) and recieved a works... no as well as the configure: error: intallation or configuration problem: C compiler cannot create executibles.

Then from there obviously the 'make' commands would not work because the config could not make a file in MakeIn folder adjusted to my system.

After searching through all the following documents and sites I Downloaded cc-4.3.4.tar.gz from http://gcc-ca.internet.bs/releases/gcc-4.3.4/ a mirror of gcc.gnu.org. I'm not sure what to do from here?
How do I install this gcc since I didn't have one.
What is a gcc? It must have something to do with a compiler.

These are the links of numerous sites I have searched inorder to find a solution:

• GCC talking about it latest releases http://gcc.gnu.org/
  
• http://www.gnu.org/ is very interesting site talking about opensource software and what they offer to all.
  
• http://www.linuxquestions.org/questions/programming-9/gcc-compiler-..-245576/
  This is a linux forum telling me that if I don't a gcc, then to go and get one from gcc.gnu.org
  
• http://www.linuxquestions.org/questions/linux-software-2/checking-for-c-compiler-default-output...-configure-error-c-compiler-cannot-create-183861/
  This is one of the many forums that had the same error from different programs or different Linux Operating Systems.
  
• http://ubuntuforums.org/showthread.php?t=356729
  Well with a similar error on the compiler not compiling executable files I followed this forum and found this result...from a user.
  
  I GOT IT! The problem was in the kismet instillation, not the driver like i thought.
  Solution:
  install libpcap 0.8
  ./configure
  make dep
  make
  make install
  I knew it was something stupid.
  I tried 'make dep', but difference since I believe the problem lies with the fact the comiler doesn't work.
• http://tcpick.sourceforge.net/?t=1&p=INSTALL
  is another link that I hoping would help me.
  I read some of the code that looked rather similar to the instruction code from other forums.
  It also reffered me a URL different from the one than I had already downloaded the program 'libpcap'
  
• http://www.nabble.com/-MacPorts---21062:-Snow-Leopard,-fresh-install,-can%27t-install-any-ports-td25281545.html
  This is another piece of info I found on MacPorts.
  Okay well I figured it out for anyone who cares... the Xcode installer that you download from Apple does not install the Unix development package. You have to use the one included on the Snow Leopard disk.
  
• http://www.securityfocus.com/infocus/1421
  this is where I got the instructions to install 'libpcap'.
  It also has instuctions on trouble shooting and understanding SNORT
  
• http://www.snort.org/downloads
  I downloaded what I could see as the latestt SNORT from this site.
  
• http://ubuntuguide.org/wiki/Ubuntu:Jaunty#setchangeenablerootpassword
  this site taught me how to change the 'root' password
  
  I was also reading the Install.txt from libpcap, but it only gave me thesse errors to choose from: If configure says:
  configure: warning: cannot determine packet capture interface
  configure: warning: (see INSTALL for more info)

Advanced Speadsheets with Microsoft Excel: Beginning

Pondering: Starting with today's work the first exercise proved simple and purposeful because of the pre-reading and examples I completed. The examples became, as discussed in class, more difficult to understand and less practical. I find the business, finance, and managerial viewpoint and application of Information Systems very interesting.
Learning: One must read the text before assuming that the exercises are inapplicable to the text. Read, learn, before you work.

Cell Phone Fix- No Sound

If you encountered a similar problem than this information will be very useful to you. In fact a good quantity of users experience this problem about a year and a half after purchase, that they cannot hear the sounds from their phone when they make a call.
Many say that they had recently used an ear jack so that they could talk hands free and after removing the ear jack their button sounds and conversations were frustratingly unheard.

Error / Problem: No Sound on cell phone when conversing. No sound from keyboard.

Verify that on the volume of the buttons and conversation settings the status of "Ear jack-In" is on the top. This verifies that the phone still believes the ear jack is plugged in.
Go ahead replug your jack back into the phone... the sound is back and the phone works fine with he jack plugged back in. However, to get the phone to work without the jack plugged in will take a small effort of work on your part.

Research: I read various forums to figure out that many users experience this same difficulty with their phones. All of their solutions were obsolete, but got me thinking of what hadn't worked and what could work. My proposed solution was based off of a USB port problem that I had experinced months prior.

Hypothesis:

• Plug in ear-jack.
• Turn phone off.
• Pull out the battery for 10 seconds.
• Remove the ear-jack. Reinsert the battery.
• Turn phone on.

Results: Positive result confirmed. The phone functions as normal without the ear-jack needed.

Afterthought: Problems have similar steps that can be used to solve them. Also, forums are the greatest. They allow common folk to see an error that has beset many and after analyzing, can find a solution whether stated or not.

Forensic Computer Tools

PhotoRec proved to be a huge help.
Some one whiped thier hard drive, but as all should know it's difficult to really erase everything off your hard drive; so I used PhotoRec a free open source tool used to recover lost files. It will recover picture files, web files, word proccessing documents and more.

USB device not recognized

Problem: I have had some trouble with my XP sp3 PC. My mouse and printer still function; however, the mass storage devices, like my 500GB External HDD and my flash drives, bring up the error "USB Device not Recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it."

Reserach:
I searched some support articles through Microsoft's support website, only to find that all their solutions didn't function.

This article,however, provides a great deal of options.
http://www.ntcompatible.com/Desperately_need_help_---_USB_Devices_Not_Recognized_t32356.html

Hypothesis: I have al;ready tried to update drives, scan for updates in hardware, reboot my computer, and change power settings on my USB Root Hubs.

I am going to now attempt unplugging all the USB drives and then turning off the computer and then unplugging the cable from the wall.

Yes, it worked...All is well!
