| Description: |
(This course is 3 credit hours long.)
This course covers the concepts and administration of system and network
security on Unix and Linux systems.
Students will gain the skills needed to protect Unix and Linux servers
from various types of threats.
Students will understand, plan, and implement security on Linux servers
including developing security policies, local system security,
network security, monitoring systems and networks, basic firewall setup,
and the use of various security related tools (e.g.,
PAM,
sudo).
| ||||||||
| Objectives: | After completing this course, the student will be able to:
| ||||||||
| Prerequisite: | CTS 2322 (previously called CGS 2764) or permission of the instructor. Students enrolled in a degree or college credit certificate program must complete all prerequisites. Note! HCC registration computers may not check for prerequisites before allowing you to enroll. Be certain you have all required prerequisites or you won't have much of a chance of success. | ||||||||
| Facilities: | Assignments can be performed on the Dale Mabry campus Linux computers,
which can be accessed from the classroom or from some computers the
open computer lab.
YborStudent.hccfl.edu (a Linux server) can be accessed from
on or off campus and can be used to practice, examine configuration files,
read man pages, and do some assignments.
From off-campus you can also practice using any Unix/Linux system available
(or install Linux at home).
You will also use the
YborStudent Wiki for some of your work
and having class on-line discussions.
You will need your own floppy/flash disk, writing materials,
and Scantron 882–E or 882–ES forms.
You can use HawkNet
(WebAdvisor) or
FACTS.org to obtain your final grade for the course.
HCC DM Open Lab Computers are located in the computer science department open lab in DTEC–462. Lab hours are:
Lab Techs) are not teaching assistants or tutors, and shouldn't be expected to help you with your coursework.) | ||||||||
| Grading: |
Grading scale:
A=90-100, B=80-89, C=70-79, D=65-69, F=0-64 (Collaborating on the class wiki counts as up to 5 points extra credit, as does active class participation. See below for details.) | ||||||||
| Policies: |
| ||||||||
| Projects: |
Projects will be assigned from the class web page
at various times.
You will have sufficient of time to complete the projects,
at least a week but usually two weeks.
Although there will be some group assignments you
must work individually on the non-group projects.
You may work together in small groups on group projects,
provided the names of all who worked together are listed.
Each student must still submit their own copy.
Projects are typically completed outside of regular class
hours.
Projects are graded on the following scale:
A = 95% (Excellent: Good design with good comments, style, and extras) Minor extras worth +5 points, minor omissions or poor design worth -5. Projects are not graded when turned in. They are graded all at once, sometime after the project deadline has passed (usually the next weekend). Further details will be provided with your first project. (See also submitting assignments below.) | ||||||||
| Wiki Assignment: |
Extra credit can be earned by updating the study guide on the
class wiki
with a substantial contribution based on the material covered
in class, from assigned readings, or from other resources you
have studied.
A substantial contribution means adding new material,
adding references (links), or elaborating (or correcting) some
previous submission.
You should use
wiki formatting and not HTML formatting when
possible, and be sure to spell-check your work.
The wiki will automatically send your instructor an email for each
update, so there is no need to add your name to your contribution.
Your instructor is the editor and moderator of this study guide (and for all material posted on this wiki site). While some time will be given for students to correct postings, in order to ensure an accurate study guide the instructor may edit, add to, or remove material posted by students. The wiki assignment will be graded on or after the following week (so you have through the weekend to post something for the previous week). Your contributions will be graded based on correctness, completness, and clarity. Note regular posting is required to earn extra credit; one large post the last week of the term will not earn much (or any) extra credit. | ||||||||
| Submitting Projects: |
Projects should be submitted by email to
.
Please use a subject such as Unix/Linux Security Project #1 Submissionso I can tell which emails are submitted work. Send only one assignment per email message. Email your projects by copy-and-paste into your mail program. (Please do not send as attachments!) If possible, use the textand not the HTMLmode of your email program. Do not send any email to wpollock@YborStudent.hccfl.edu as I may not read that
account regularly.
In the event a student submits more than once for the same assignment, I will ignore all but the last one received up to the deadline. Projects submitted after the deadline will not count toward your grade except as allowed by the course late policy.
The HCC email server automatically accepts and
silently discards email with certain types of attachments.
If you must send email to my Internet (non-YborStudent) email
account please avoid using any attachments, but especially
To avoid having your submitted work rejected as If you have an email problem you may turn in a printout instead. Be sure your name is clearly written on the top of any pages turned in. Please staple multiple pages together (at the upper left). |
