ACLs scenario

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
I've been given a homework connected to ACLs in Squid. Unfortunately
there is no way to simulate the environment so I wrote acl rules off
the top of my head. So please, check it.

Probably there is a mistake in the scenario. Designers and programmers
are in the same subnet and they should have different rules which I
think is impossible. I know that it's long but I've tried to write it
clear. So please, be patient and help.

Scenario given.
President has a PC and notebook with MACs specified (08:00:27:81:08:73
and 08:00:27:84:24:BF).
Managers have three notebooks with MACs specified (08:00:27:E7:D5:37,
08:00:27:82:59:C5, 08:00:27:C3:BE:B8).
Designers and programmers have computers in 192.168.2.0 subnet (their
PCs are DHCP clients).
An Administrator has notebook with 08:00:27:EB:D7:94 MAC.
A secretary and an accountant have PCs in 192.168.3.0 subnet.

And here are the rules which should be applied.
1. The president has unlimitted access.
2. Managers are denied to access to entertainment websites (community,
movies, music) form Monday to Sunday during the working hours (8 - 16)
3. Designers are denied to access to entertainment websites all the
time and their cannot download movie, music and exe (except Windows
updates) files
4. Programmers are denied to access to entertainment websites all the
time and cannot access to info websites such yaho_ com, newsweek _com
during the working hours in working week.
5. An administrato has unlimitted access during the working hours.
After, he is not allowed to access to entertainment websites.
6. A secretary and an accountant are denied to access to entertainment
websites during the working hours and their cannot download any files
from the Internet except xls, doc, gif, zip, txt files.
