    It's amusing that people focus on the latest-and-greatest security software, which IMO is more counterproductive than it is productive.

    You get a whiz-bang anti-virus/firewall system set up and what does it do? Give you a false sense of security so you can feel more confident about engaging in irresponsible computer use. The problem is almost every piece of security software out there has at one point or another been vulnerable, so you're flirting with disaster.

    I think no matter how many advances we have in this area, the basic rules of security will always apply:

    1. Limit Accessibility.

    99% of security issues are inside jobs. Limit physical access to your resources. Don't put any sensitive data on a machine that anyone else has access to that you don't want public. Use encryption, multi-wipe free space and turn off your machine when you're not using it.

    Some people don't want to hear this but it needs to be said: DON'T USE WIRELESS if you're worried about security. No matter what precautions you're taking, by going Wireless you dramatically lower the integrity of your personal security PERIOD. It's one thing to use wireless on the road, but you should limit the sensitive information on your laptop in the first place because it's mobile, but it's really just plain lazy and irresponsible to run wireless in a permanent installation like your home if there is any practical way to avoid doing so.

    I can't stress this enough: *unconditionally* WIRELESS IS MUCH LESS SECURE. It doesn't matter what protocol/encryption you're using, by going wireless you introduce additional ways your system/data can be accessed.

    Remember the first commandment: True security is more dependent upon reducing access points than it is implementing protection of access points.

    2. Disable ALL non-critical services. Don't run anything except what you need on your PC. Close all unused ports; remove all services and extra features and plug-ins that aren't needed. The fewer systems, the fewer points of vulnerability.

    3. Keep all software fully-patched and up to date.

    4. If possible, never use the "industry standard" software if it's not the most secure solution available. Dump IE and Outlook and switch to Firefox and Eudora.

    5. TEXT ONLY E-MAIL... This, after #1 is IMO the biggest threat of them all. The added superficial benefit of html-email is not worth the security liabilities that come along with it. If you want to use html e-mail, I'd recommend a second, sandboxed account for that.

    6. Never put a machine on public-addressable IP space unless it's a public server. Use a DSL/cable switch and put your systems on a VPN on the other side of a hardware firewall that filters out all non-essential traffic.

    7. After you've taken care of 1-6, then and only then should you consider anti-virus/spyware and related software to be a useful addition.

      STO is when you use unpublished methods and rely on the attacker not bothering to try to reverse-engineer your system as a method of protection. Examples are using XOR and similar cyphers in obfucated ways to hide the details.

      So far RSA has not been compromised. Until such a time using RSA in open and peer reviewed protocols (remember that RSA etc are only a small part of the big security system) is in no way "Security Through Obscurity", it is in fact Best Practices (tm) and that is pretty fucking far from STO! And if a really good way to factor into primes comes up then you CHANGE the encryption scheme!

      Most people have a grasp of just how many combinations there exist in a 2^1024 key. As far as we know the number of atoms in the universe (including dark matter and such) is on the order of 2^200. Now in RSA and other asymmetrical systems not all keys can be used, but still I'm willing to guestimate that a typical 2^1024 key has way more than 2^1000 valid keys (I can't be bothered to do a real estimate, and that's probably way to small).

      Now consider that the Universe is Pretty Damned Big, yet the number of valid keys completely dwarfs that. It is hard to put into words just how completely unlikely you are to brute-force an RSA key (or any other key for that matter). Just imagine all the absurd unlikely events EVER happening to you in the same microsecond. Then multiply that by about 50 billion times and you'll still be ways off, but you'll get the idea.

      In short, you are not going to brute force a key which is even 2^256, it's just not happening.

You must be constantly vigilant to detect intruders as they attempt access, you must have a recovery plan if you are compromised (everyone needs AV software and an individual firewall on each computer behind the NAT firewall), and must be sufficiently auditted that you can trace access attempts back to the source. Watch your wireless traffic - with this type of security, in the very very remote chance you are compromised, its going to take a long while.

      I have to respond. The parent was correct. It's amazing seeing what people do to run windows, and what I've had to do in the past.

      You say you seriously doubt anyone has done a fresh install of distro-of-choice and not spent time tweaking things to get the system fully usable. Then you go on to say you're hoping to build your first linux box.

      I think you'll be pleasantly surprised, depending on what distro you choose. Someone below mentioned OpenBSD, and that's a good recommendation. I think you'll find that a fair amount of the unix-y environments start you off at a solid base, and allow you to build up. This is in contrast to whenever I have the (in my opinion, of course) displeasure of dealing with a windows install, where I have to tear down and build up.

      No, not all distro's are the same. Sometimes they have annoying services listening on all interfaces, like cups or lprd. That's one of the reasons why OpenBSD is nice. It starts you off with a good base from which to build up. I have recently switched to the excellent ubuntu distrobution from debian sarge. I am pleasantly surprised by the fact that very few services are listening by default, so there's really not all that much to do to "secure" the box (at least from a basic point of view). In fact, when I installed ubuntu over debian, I kept my old home directory, so there was no tweaking to get my desktop how I want it. I guess you could do the same with windows, but it's a pain to mess around with the registry to point to a different location/drive for user's home folders. All I have to do is mount the old volume as /home and it works fine.

      Not only that, but the installation of new software is tremendously easier for the unix-y domain, at least debian, where apt-get is very good at solving your problems. No cds to look for, no keys to look for, makes it all very easy. So I think you're making a kind of incorrect blanket statement based on your experience with windows (it seems).

      That said, I prefer the old tiny personal firewall, but only the old version (2 or 3?) as the new one doesn't have as nice an interface. It seems to barf a fair amount when installed on XP, so I'm actually shying away from that these days. You didn't say which version of windows you're using. I've been using the virus scanner from etrust, free to valid microsoft users: ezarmor. It seems to work okay, and it's free. It also includes a firewall of sorts, but I don't recall being very impressed, so I installed tpf again. AV gets rather expensive, rather quickly. I purchased the symantec AV/Firewall suite for something like $50. As always, there's a linux NAT box protecting it all, allowing easy port forwarding. I've also used the linksys wrt54g and it seems to work okay. It's available pretty cheaply now, and allowed me to reduce the number of crud that clutters up the gf's apartment.

    What VPN hardware is best? We bought a NetGear FVS318 hardware firewall/router/VPN for a customer, and discovered that the remote administration password is openly transmitted. We found that logging out in the remote administration menu didn't always actually log out. We found Javascript errors. With the 2.4 firmware, more than one client can be logged in at the same time. That situation, two clients at the same time, would give an error message with the 2.3 firmware, so things seem to be going backward in some ways, in firmware that is already shaky. Our experience with Netgear technical support is that it is very limited. On the telephone we got someone in Tamil Nadu, India, who was allowed to practice for a short time with Netgear equipment, but who doesn't any longer have access to actual equipment. The online tech support just gave error messages. Not only that, but Fry's and Netgear arranged a rebate trick.

For example, you can specify the remote address directly as either a port or as a "display number". The other ones make you enter a display number, which is clunky if you only know the port ("display = port + 32500" or something arbitrary like that.) Just little things like that.

      >What security is best? Is it good to use a VPN for secure access, or is SSH better?

      VPN is a vague term. In some contexts you can use SSH to create a VPN. For example, let's say I want to pop my mail from my mail server. But POP3 shows passwords in plaintext so I don't want to do it over the wire. Plus it's just for me so I don't want a POP3 server listening on a public interface if I don't have to. So I setup a ssh tunnel, and forward ports 25 and 110 across it. Now I just enter "localhost" for POP3 and SMTP servers in my email program and viola! I use the "autossh" utility (run as a Windows service) to maintain the tunnel, using RSA public key authentication for secure passwordless login. I don't even have to think about it or touch it, the service starts up at boot and seamlessly sets up the tunnel, and restarts it if it goes down.

      You can do something similar for lots of protocols.

      Yes, but "security through obscurity" is a technical term of art. It's either ignorant or disingenuous to use English-language definitions to define a technical term when that term is clearly used in context. Yes, the private key in an RSA implementation must be "obscure" in the English sense for the system to be at all secure.

      But, as wikipedia puts it (you can read more there):
      "In cryptography, the reverse of security by obscurity is Kerckhoffs' principle from the late 1880s, which states that system designers should assume that the entire design of a security system is known to all attackers, with the exception of the cryptographic key"

      This is supported by how this term is used in practice by experts in the field.

      The key principle of systems described by "security through obscurity" is that the _design_ of the system (algorithms, etc) is hidden.

      The key to non-security-by-obscurity systems is that the design of the system is public so that it can be publically audited and the assertion that "it's secure when used with any key that satisfies condition X" is well-vetted (X is usually: "Product of 2 large primes", in some algorithms it may be "Never reused" or "not a Weak Key" for some rigorous definition of weak key, in some algorithms other ). It's also usually key that there is a good objective test for condition X, such that implementors have a high degree of confidence that not only is their crypto implementation basically sound but that the keys they implement are believed to be secure as well.

      More generally, in non-keyed systems it's not considered reliant on "security through obscurity" if the system architecture as a whole is well-vetted and the conditions that are prerequisites to security are documented and objectively testable via some well-vetted method.

      Of course, you probably already new that and were trying to change the accepted definition by arguing against the OP based on an idiosyncratic (within the context) definition.

    Oh come on, lets not be hypocritical here. I seriously doubt anyone can say they've done a fresh install of *distro-of-choice* and not spent some time tweaking things to get their system into a fully usable state.

    Yes, but generally once you've done an fresh install of *distro-of-choice* you at least have the chance to get it on the network before it is hacked to death. Windows XP's basic install has gotten so far out in terms of security that a fresh XP install is generally compromised within *seconds* of being put on the network... far faster than you can download the patches to make it secure. The only way I can do XP installs these days is by putting it behind another machine that protects it from malicious attacks while it is made secure. Now compare that to Debian, which installs the latest everything by default, or even the likes of Mandrake which keeps a relatively current version for download, the XP install / update process is surprisingly difficult.

    1. Re:compromised in seconds by nullportal · · Score: 1

      I can personally testify to the near instant hack to death of XP re-installs and SP2 upgrades to get a firewall in place.

      Once you are in a loop of hacked machines, which I got stuck in during August, they will recontact you within *seconds* of your having a live connection to the net. For me, a Verizon DSL subscriber, subject to numerous and sometimes successful backdoor assaults (nothing to do with email or other overt contact threats) because Verizon insisted I turn off my firewall when installing their code, I had to wipe the disk and reinstall XP several times before I finally learned that you can NEVER NEVER have any live modem connected to a powered computer without your firewall on and blocking everything you don't allow, every second from the first second. The attacks start coming at me LITERALLY within seconds of making net contact, and do so everytime I power up my machine these days because of prior involuntary membership in a circle of hacked machines, though they are all simply rejected now.

      Ultimately, calling Verizon tech support got me the info that I can indeed set up my Verizon DSL account with their software with my firewall on, it just goes slower, but they won't tell me of every IP and port available to that IP that I need to have open to best connectivity to Verizon servers, so I have to sort of drive-by-brail to figure out which IPs and port calls are attacks and which are necessary to setting up the Verizon account when setting up. It's no wonder that most of the other infected computers attacking me the second I come on line are OTHER VERIZON customers who haven't figured out yet just how far they've been hijacked, thanks to Verizon's "turn off your firewall while you set up your account" crap.

      Yah - you can't even take a breather as long as to download the latest updates from MS and to set up your DSL account, etc., without your firewall on from the first moment of electrically live contact to the net. I can peronsally vouch for that, more times over than I care to.

    I will admit that I have taken "security by obscurity" to it's logical literal extreme here, which is indeed an ideosyncracy of mine. It's not that I'm particularly trolling - It was originally because someone disagreed with my assertion that RSA was not secure in an absolute sense, which I (still) believe is utter tripe.

I tried using a Panda 7.0 that I got talked into buying with it by a salesman who shouldn't have, but I switched back to the Norton preloaded because I came under a swarm of sometimes successful backdoor assaults and Norton allows me to relatively quickly integrate information about attacks and not have to rely on 3rd party software for various threats. It's "all in one".

    For the last 3 days I've mostly been firewalling off a place called China with permanent refusals to allow connection, as various Chinese domains host attempted backdoor attacks on me, because of a steady stream of attacks seeking backdoor access (nothing to do with email or other overt contacts), but according to some news, those might ultimately stem from N.Korea routing through China. Unfortunately I'm a Verizon DSL subscriber and utterly responsible for all my own security at home, got successfully backdoored before I switched back to Norton, and I'm now stuck in a loop of other infected Verizon customers so that within 30 seconds of connecting to the net they all try to recontact me and reinstall me into the Verizon DSL infected customer loop, all on top of a steady stream of backdoor attacks routing through China.

    Last night in one somewhat sleepy moment I accidentally permitted an unusual port contact (thought I was clicking on "block" but it slipped to "permit") and immediately got my host reset to an IP I can't even find in databases.

    I suspect the recent resignation of the Homeland Security cyberdude has something to do with a massive attack on the US routing through China, which for whatever reason the administration is not willing to take the obvious steps about. So here I am, stuck applying my own personal UDP to any block of net addresses that I can find that are from China. They still come at me from other countries and the occassional hijackable computer in the US, though.
