VIRUSES and WORMS

only allows connections that you specifiy to interact with your
computer
- Were you expecting this
message?
Other issues covered: SPYWARE,
NETWORK SNOOPING, PASSWORD SECURITY, DATA LOSS, COMPROMISED
CONFIDENTIAL DATA
Discussion
- Is Internet II an alternative
to security problems? No, according to Judd. Environment is too
open.
- Alternatives to sharing
executables via email is a viable policy, but hard to implement
in an academic environment. Keep in mind that email
- Are commercial ISPs
using tools that we are not? No magic bullets. Must strike a balance
between restrictive and open computing.
- Wireless access requires
use of encrypted protocol. This is a campus standard.
- ATN is happy to provide
security reviews and presentations for departments.

Online instruction (asynchronous)
Teaches AFAM 140 course
through Friday Center. Enormous demand for this course. Doesn't evaluate
students on what data they have. Is looking more for compelling arguments
that can't be downloaded off the Internet. Represents change in the
way he has taught the course. Uses discussion forums and has recently
started dividing students into groups of twelve or less. Tim pays
attention to discussion, but only responds to active threads. Grades
performance (structure of argument) on discussion forums. Provides
students with feedback. This substitutes for face-to-face class time,
and now accounts for 20% of grade.. Don't have the time to use these
in residential class (80 students). Just doesn't the have time.
Students in online class
have access to a wealth of online resources.
Advantages to online
courses
- Racial anonymity (especially
for AFAM)
- Accommodates working
and pregnant students
- Self-paced
- Equity in discussions
Disadvantages
- Potentially alienating
- Computer literacy
issues
- Economics of hardware
and access
- Self paced
- Out of sight/out of
mind
- Plagarism (now must
structure paper topics differently....essentially topics that
aren't represented on the Internet)
How are students who
live in remote locations dealt with by the Honor Court?
