Ask Slashdot: Is Running Mission-Critical Servers Without a Firewall Common?

avgjoe62 No and Hell No (339 comments)

If a developer or vendor cannot tell you what ports and protocols their software uses it is time to re-evaluate how much you need their software.

In most companies of any size that I have been involved with an application portfolio would need to list the ports and services that it would use.

You could also turn off the firewall, run nmap against the system and see what ports are open. Ask the developers what their application uses from the ports discovered and then turn the firewall on again. Then block what you don't need and open what you do. Yeah, it's a pain in the ass, but not every machine inside your network is always going to play nice with everyone else, so firewalls on important systems are needed.

New Mayhem Malware Targets Linux and UNIX-Like Servers

avgjoe62 Re:Whitelisting with mobile admins (168 comments)

VPN to an admin workstation in the DMZ. That admin workstation will of course be on the access list.

Or you could run a virtual firewall (running an Open VPN client to your main firewall) and admin station inside your laptop and tunnel from your workstation to your firewall.

There are a ton of ways to do this depending on the time and options you have access to.

New Mayhem Malware Targets Linux and UNIX-Like Servers

avgjoe62 Re:Derp (168 comments)

Firewall. Whitelist. Limit access to SSH to systems on the whitelist.

No need to block entire countries - just allow SSH access to those systems that need it.

Now, if you want to talk about blocking access to your web or mail server from anyone in East Elbonia, then you can implement a package like Country Block, or use a service like this one, depending on your firewall.

The lesson from this? Restrict access to important services via a whitelist, block access to public services with a deny list.

Oklahoma Botched an Execution With Untested Lethal Injection Drugs

avgjoe62 Re:What's the problem? (1198 comments)

Apples and oranges - there is a difference between killing those that you are certain beyond any doubt are trying to kill you and killing those that you are sure only beyond a reasonable doubt killed someone else.

Oklahoma Botched an Execution With Untested Lethal Injection Drugs

avgjoe62 Re:What's the problem? (1198 comments)

I too would prefer the guilty walk free over the innocent being condemned to death. This has nothing to do with the crime, but rather the punishment. I would rather imprison every convicted murderer for life rather than execute one innocent person.

"Many that live deserve death. And some that die deserve life. Can you give it to them? Then do not be too eager to deal out death in judgement. For even the very wise cannot see all ends." - Gandalf, The Lord of The Rings

Study Rules Out Global Warming Being a Natural Fluctuation With 99% Certainty

avgjoe62 Re:...a doubling of carbon-dioxide levels in the a (869 comments)

February 2014 was the 21st warmest February on record since 1880. The temperature was yet again above the 20th century average, for the 348th consecutive month. That is every month above the 20th century average for the last 29 years. Please, tell me just how you determined the temperature is going down?

NASA Wants To Go To Europa

avgjoe62 Re:What could possibly go wrong (216 comments)

The first person to write it down - in other words, history is told by those that wrote the book - is the "Discoverer", because when people two hundred years later wonder who 'discovered" this place, they go look in a book.

Like in any relationship, thing are always changing. One partner moves a little further away, the other becomes disinterested and soon one of them just doesn't understand the other.

Whole Foods: America's Temple of Pseudoscience

avgjoe62 Apples and Oranges (794 comments)

I regularly shop at three different supermarkets, one of which is Whole Foods. I like their produce. I like Publix for bulk goods like pasta and flour and TP. I like The Fresh Market for their fish and meat. I can separate the pseudo science at any one of these from the products I am buying. I only worry about price and quality of what I am buying, not the hype that surrounds it.

The Creation Museum does not sell me anything useful. The hype surrounding their "product" is exactly what they are trying to sell and I am not buying any of it.

At Whole Foods I can buy an orange without buying a belief system. At the Creation Museum, the apples come with a whole set of beliefs attached to them.

Facebook Analyzes the Impact of Love On Their Business

avgjoe62 An Old Quote (37 comments)

Why are there so many sad love poems as opposed to happy ones? When you're happily in love there are better things to do than write poetry.

I suppose the same applies to Facebook postings - when you're happily in love, there's better things to do than write on someone's wall.

A Strategy For Attaining Cuban Internet Connectivity

avgjoe62 Re:Not going to help (119 comments)

I am certainly no fan of Castro's, but I do not blindly hate the man and froth at the mouth every time his name is mentioned. While I do not think it is worth anywhere near the price the people have paid, there are some things that Cuba does get right.

Look at this page from the CIA World Fact Book and look at the relative positions of the US and Cuba.
