Operating System Market Shares
Ryan (2008)
We need to question whether or not Windows is indeed the best, or more importantly, the safest operating system!
Is windows the safest Operating System?
Absolutely Not!Why?
Why?Why?
How?
Let me explain why technology is bad!
Insecure Design
Windows PCs
Viruses
Trojans
Malware
Spyware
Security Weak Points
Open Ports
Firewall
Unrestricted Access
99% of time computer is being run as Admin
(“Microsoft Windows:Insecure by Design,” 2003, p. F07)
Mac and Linux Permissions
99% of the time you can, and SHOULD, use the PC as a
normal user that does NOT have access to change or modify the
system
(“Microsoft Windows:Insecure by Design,” 2003, p. F07)
So why doesn't Windows offer more secure options?
Unrestricted access is simple.Huge market share means no
pressure to change.
A Checklist to Help Secure Your Windows system
Use NTFS on all your partitions
Disable Simple File Sharing
Use passwords on all user accounts (windows lets you create users that don't have passwords!)
Disable the Guest Account
Use a firewall better than Windows version.
Install Anti Virus and Spyware programs
Keep up to date with hotfixes and service packs
Make sure that Remote Desktop is disabled
Disable unnecessary services (such as the “messenger service” we discussed earlier)
Disable default shares
Keep in mind, all these changes still don't guarantee a secure system because most users have unrestricted access!
Windows XP Security Checklist. (2006)
Steps to Secure Mac and Linux
Turn on computerCreate administrator accountCheck firewallCreate restricted user account to use 99% of the timeGet automatic updates when available
Why should you be concerned?
Top viruses and threats to computers.

How bad can it really be?Crime:In 1988, one of the first Internet worms was created by a Cornell University student named Robert T. Morris The worm, rightfully called Morris, crippled approximately 6,000 of the 60,000 computers online at that time. That's 10%! It caused between an estimated $10 and $100 million dollars in damage.
Punishment:$10,050 fine3 years probationTeaching gig at MIT!
Crime:The Melissa Virus was named after a Florida lap dancer favored by it's author David L. Smith. The Melissa virus was so severe it forced Alcatel-Lucent, Intel, and even Microsoft to shut down their e-mail systems.
Punishment:$150,000 fine and 40 years in prisonreduced to 20 months and $5000!for working undercover for the FBI to help catch other hackers.
Crime:Code Red and Nimda of 2001 took the world by storm!
Nimda took just 22 minutes to spread worldwide by creating masses of e-mails and sending itself! You could also get this worm simply by visiting an infected website!
Code Red infected Microsoft IIS Web servers and drastically slowed Internet connectivity world wide costing an estimated $2.6 Billion in damage.
Punishment: None! Authors never found.
Crime: Sasser 2004 spread across Windows XP and Win2000 machines forcing Australian trains to halt, and grounding 40 trans-Altantic flights from Delta Air.
Punishment:21-month suspended sentence!The code was written by a German teenager who was tried as a minor!
(Kretkowski,2007)
Threats of the past?
What about now?
What about the future?
What about new operating systems like Vista?
Surely the world must care?
And be doing something about it!
I rarely use the computer
So how much does it really affect me?

Technology is not bad
The users lack of understanding technology is bad!Technology can NOT exist without the user!Until society is ready to take the time to learn and understand the dangers we cannot risk such vast use of technology that we currently utilize!Our finances. Our confidentiality. Even our LIVES are at risk!

Teacher Roles In Technology
Common Reasons for Improper Technology Use
Irresponsibility
Naivety
Unawareness
Lack of Knowledge and Actions
Example One– Irresponsibility
“A Charlotte-Mecklenburg Schools teacher faces firing for posting derogatory comments about students on
Facebook, while four others have been disciplined for posts involving ‘poor judgment and bad taste’”
(Doss Helm, 2008)
Teacher Roles in Technology
Poor Leadership
Disrespectful to Students
Inappropriate Behavior
Poor Role Modeling
Pictured above is the teacher in question
Teacher Roles in Technology
Reader responses to the Charlotte teacher:
“Issues of proper social networking behavior face our schools every day. Students (and teachers) need an effective curriculum that teaches expectations and
protocol.”
“I am completely shocked! I think it's everyone's right to social networking. However, as teachers, we have to
know where and when to draw the line.”
(Doss Helm, 2008)
Example Two—Inappropriate Actions
“If there was any doubt about the power of blogs, consider the case of Michael Gee. A part-time journalism professor at Boston University, Gee
was fired recently after he posted comments in a blog about the looks of a female student in his
course.”
(Roberts, 2005)
Teacher Roles in Technology
Gee was guilty of:
“Violating the trust essential to the student-teacher relationship."
(Roberts, 2005)
Example Three– Naivety & Unawareness
Jeffrey Spanierman, a teacher from Connecticut, created a MySpace page
"to communicate with students about homework, to learn more about the students so he could
relate to them better, and to conduct casual, non-school related discussions”
BUT…
Teacher Roles in Technology
One of his colleagues reported the page which contained nudity, inappropriate comments, and
personal conversations with students
RESULT: TERMINATION
(Neuburger, 2008)
Legal Issues
-- Is the school public or private?
-- Are there state statutes that impose standards on the teacher, or obligations on the school with respect to teacher discipline? -- Did the conduct involve expression that may be protected by the First Amendment?
-- Did the conduct have a connection to the school environment?
(Neuburger, 2008)
