How can I enforce a firewall -- built-in or 3rd-party -- in OS X, such that even someone with an admin account can't disable it? [more inside]

Yesterday I added a network print server device to my home network. How can I know that it is secure? Can I firewall it to prevent it from sending anything out to the internet? A few more details inside. [more inside]

Please help me configure and secure my Ubuntu-based combined home file server/public web server/VNC server! I am building a low-ish power home file server, which will likely run Ubuntu 11.04 or 11.10 (possibly server edition), and I should be able to set up a basic samba share easily enough. But I would also like to use the same computer to serve a few basic webpages, and I would like to provide ssh and ideally VNC or RDP-like access from outside the LAN. I can probably get the basic software set up, but I'm a n00b when it comes to NAT stuff, firewalls, and security issues generally. I would also appreciate help with setting up dynamic DNS.

I allowed perl access past my firewall (Am I even saying that right?). Should I be worried? And how do I learn more about the subject so I'm not so clueless in the future? [more inside]

Simply put, I would like to determine which (outgoing) ports are open and which are closed on my company's network. They have a firewall blocking most ports...so far I can only get through port 80 and port 443. I know for example, ports 23, 25, 110 and 6667 are blocked.
So I may be over-thinking this, but what I think I need to do is find a way to listen on all ports (or at least a select list) on an external computer, then scan that computer's IP from inside the network to see what connects...
The catch: I would like to open these ports for connections without having to install servers that actually use those ports. If we're talking a couple hundred ports, I don't want to install and configure a couple hundred server apps. (or all 65535?)
Does anyone know of an app that will open 'fake' ports on a system and respond with some sort of generic server type?
I know I've seen such an app before, but I just don't remember what it was called, and my google skillz are not coming through this time.
Side note: I originally thought what I was looking for was a "leak tester" ...but this isn't quite right, as it is testing incoming ports, not outgoing ports.

I noticed this morning in my system logs that I had some failed FTP and SSH login attempts from an IP in China. I thought I was going to have get all Cliff Stoll on this guy, but then looking back further I saw that this has been happening for months, from lots of different IP addresses. [more inside]

Where can I find detailed information on anti-virus software comparisons? I've heard of and seen some charts that display details such as catch rates and etc but have never known the exact source. Something like this perhaps: http://virus.untangle.com/ but a more broad spectrum, preferablly one that includes AVG and Avast!
Also what is the best firewall for Windows Vista?

I have recently started a new job in charge of IT in a small lab <10 people. A while back the lab was badly hacked into and data etc. was lost (there is evidence this was an inside job btw). As part of my remit I am in charge of making sure this doesn't happen again.
The company has a site license for anti-virus software so that is not an issue however we currently have no anti-spyware, personal firewall or rootkit / trojan detector etc.
What I'm looking for is one or more products which I can install on the user's workstations which are effective in these areas. The most important point apart from actually working of course is that I can centrally administer the software and monitor what is going on - edit firewall rules etc.
So what products would you recommend that might satisfy these requirements. Oh yeah all users including myself are running Windows XP so cross platform is not a problem.

On my XP system, the recently installed Norton anti-worm app told me that my Netgear RP614v2 NAT-enabled router attempted to udp connect to my port number 2061 from its port 12024. However, there is no port fowarding or triggering enabled, nor is there a DMZ address configured at all. [more inside]

Is there a way to connect to gmail using pop from behind a firewall that blocks the ports they specify? Ideally over 80? I don't have broadband at home so setting up a tunnel or variation to a pc on the outside isn't an option. Thunderbird on WinXP connected behind a typical corporate firewall.

Every day for the last three weeks or so Sygate Personal Firewall Pro has blocked twenty or more port scans. In the past I would be scanned maybe once or twice a week. What has changed? I change my IP address from time to time and I know my box is secure and isn't worth hacking anyway. What gives? I'm getting tired of the blinking icon.

How 'secure' is AIM? My brother is behind a firewall and uses a proxy to connect to AIM at his university. Assuming there were people who wanted to, how easy would it be for someone within the university to read his ramblings?
