Policies- i need help with this practice question before my exam!!!
HI EVERYONE I NEED HELP WITH THIS POLICY AND CONTROLS PRACTICE QUESTION BEFORE MY EXAM, IF YOU COULD TELL ME THE COMMANDS TO HELP ME OUT I WOULD BE SO GRATEFUL. AS YOU CAN THE FORMATTING FOR THE NETWORK DIAGRAM IS AWFUL BUT A ROUGH OUTLINEOF THE COMMANDS WOULD BE USEFUL. THANKS GUYS!
Code:
- "inbound" refers to traffic arriving from the Internet, to gw1 on eth0. - "outbound" refers to traffic leaving for the Internet, from gw1 on eth0. Organisational policy includes the following statements: - only machine dns1 may make outbound DNS requests (UDP port 53) to the Internet and get back the associated replies. - no other inbound or outbound UDP traffic is permitted. Using the "iptables" instruction, construct firewall rules to implement controls that will enforce these policy statements. Note that for the purposes of this exam question, it is acceptable (even desirable) to lay each rule out on several lines where each line represents a logical chunk within the overall rule. Leave a blank line between each rule. |
Sorry, no. We aren't here to do your work for you, especially given the state of what you've posted. You need to ask specific tagergeted questions, not just cut and paste entire things in here.
btw, see that rectangular button near your little finger on your left hand? The one with "Caps Lock" written on it? Press it. |

Start by editing your post and putting "[code]" tags aroung the network layout and it might start making some sense.

Not providing you with answers is not being selfish. You'll benefit much more if you research the problem yourself (read tutorials/documentation) and ask specific questions when you're stuck at some point. When you enter a community like Linuxquestions, it'd be advisable to respect its rules. Have a look at: http://www.catb.org/~esr/faqs/smart-questions.html Quote:
