Convincing Management to Migrate to WiFi?

bergeron76 asks: "My company is currently preparing to relocate to a new location out in the suburbs. We recently received a very outrageous quote to move our computers, telephony gear, and ethernet wiring to our new office. I'm trying to convince management to switch our call-center to WiFi for a fraction of the "relocation" quote cost. The problem is that they are still considering outsourcing the ethernet wiring at an exorbitant rate! Can the Slashdot crowd help me come up with more selling points for WiFi (beyond the obvious) before I make my formal proposal?"

    And here I am trying to convince my management to NOT rollout wireless until they at least look into possible security risks associated with Wi-Fi. Seems like all the PHBs are busy trying to fill in as many buzzwords as possible.

    Look at what happened to Best Buy - they got 0wned - do it right and include an entire security overview and recommendations in your findings. Research possible scenarios and record those down too.

    If managament goes along with it, and typicaly ends up cutting your funding half-way through (like always happens), they'll skimp on security, some day the network gets compromised, and its your fault for bringing it up in wireless in the first place, that's when you whip out your documentation - stressing the importance of security.

    Apparantly my High School is adding wifi coverage next year becuase there are a lot of places in the school that haven't been wired up as the number of computers grows. Its reached the point where its impossible / majorly expensive to wire them so they are putting in a wifi network to cover them.

    While I trust some security will be used. (perhaps foolish trust, these are the people that didn't close port 80 when nimda came and flooded the network) I'm pretty sure a non trivial number of people could own that network in a hurry. We are talking somewhat sensitive data too like grades and inter-teacher corespondence.

    My question is what exactly can be done to ensure that wireless networks are secure? They will never be 100% but can they be made good enough for reasonably sensitive data?

      Not really. If you put up a wireless network you are effectively opening up your network to the public. Now if the network is already essentially public (say an intracampus network), that isn't really a problem, but if your data is at all sensitive, it shouldn't be hooked up to a public network.

      It's called Split-tunnelling, silly.

      In deploying the VPN solution, you can set the security policy so that when attached to the VPN, *ALL* traffic must utilize the VPN connection.

      The effect is that once you initiate the VPN connection, you can't even ping a device on your local segment, or on the Internet.

      Once connected, the home/roaming user is insulated as though he were on the network behind the corporate firewall.

      Cisco's VPN concentrators (formerly Altiga) behave this way... If you choose to allow split tunnelling, they can even demand that the remote station utilize personal firewall software (Like ZoneAlarm, etc) before completing the VPN connection.

      At any rate, the problem you describe has long been solved.

    I'm guessing you have no buisness recomending one solution or the other. You seem very biased at the install cost without reguard to what is being installed. Obviously phones aren't going to be moved to wireless if your in a call center. The speed of fixed vs wireless at this point is much better. The obvious security implications of wireless data floating around the office and surrounding neighborhood would also be a worry. Wireless could always be added in stages at a later time however, the costs of going back to a fixed solution after the initial move would be really outrageous. Better to do that than experiment with technologies that while undoubtedly are cool are not proven yet and as such should be handled with a long stick unless you are prepaired to take a big hit should things not work out the way you expect them to.

If it is significantly different, the submitter should suggest to the owners that they get additional quotes.

      My suspicion is that if you NEED more than 10 base T, your computers are set up badly.

      The network I'm on runs with each PC getting their own dedicated 10 baseT link to the routers. This reduces contention and fault isolation is a doddle. The servers are interconnected via 150M connections.

      Seems to work fine.

      Still, I don't think you'd want to use WiFi for everything- it works better as an overlay network for a few people to use- managers for example. If you do want to use it for everyone, then you'd be looking at dotting dozens of APs everywhere and worrying about how they interwork when they're on the same channels and stuff. It can be made to work, but it's hassle- 100 base T is dirt cheap...

      If you're looking at 802.11b for range then you'll be looking at a real-world max of about 2Mb.

      Depends on the AP and whether you have WEP switched on. I think there is a strong argument in some scenarios for switching WEP off- the security is inadequate, and a firewall & VPN(IPSEC) is needed. If you have that, setting the SSID is probably sufficient.

    Wow, that's a bold agenda! I've actually been peddling the other way: telling management about the perils of going wireless. One of the people in my office asked me, "So, am I safe getting wireless for my house?" I sent him a three page email outlining why wireless was dangerous, as well as recommended security to implement it. (Not that he followed suit, mind you -- it would have taken a gear head to implement security properly, and he didn't seem too keen on the idea of, say, building his own firewall.)

    It sounds like to make your case, you have to show that the wireless route is 1) secure, 2) cheaper / more scalable, and 3) secure. Note the repetition there. ;) Passing up security for the moment, you probably have a better handle on whether or not wireless is cheaper / more scalable than wired routes. In my office, WiFi would definitely *not* be sufficient, if that were the only network available. I know that I wouldn't be very happy if I was limited down to the 2 - 11Mb/s of 802.11b at the office, especially when, say, transferring large files or routing large documents. If you have the numbers that say that the bandwidth is "sufficient", fire away!

    Unfortunately, whatever proposal you present *has* to have a security focus. You *have* to make the emphasis that wireless is secure enough, and you *have* to be unyielding on the security measures necessary. The main problem with this is the fact that you are surrendering the security of closed wired networks for an open-air, wireless one. Sure, you may have convenience in terms of setting up connections, but you're going to have significant additional headaches making sure things are secure. Some thoughts? Try to get everyone to use IPSEC. Oog, it's ugly and non-simple, but it's what you would have to do if your paranoid. Just thinking about plain-text passwords flying through the ether makes me dizzy from a security standpoint. Drive-by hacking is all too easy and cheap to do. *sigh*

    Of course, you're really trying to push the proposal past a manager, right? So perhaps your focus should be on how it's keeping the company on top of cutting edge, alternative technologies to proactively seek out the most cost-effective methods for maximum deployment capacity. *heh*

    You might want to reconsider the choice of an SMC Barricade. While it has OK range, it's not the best.

I have the Linksys, and a friend/coworker has the SMC standalone. Both have at least a 50% greater range than the Barricade (Linksys's is 50%, the standalone SMC's is about 70%-80%).

    Plus, this friend originally had a Barricade, and got absolutely *awful* reception in his house. The switch to the WAP-only SMC product (wish I could remember the name) greatly improved his wireless experience.

    Of course, if you *need* the other features of the Barricade, and live in a tiny area (like a 1 bedroom apartment), you might be OK.

    I think you really need to put the wireless network outside any firewall you may have; and access corporate data via VPN software. Anything else is begging for trouble.

    Being outside the firewall, the security aspects are much reduced, making it questionable whether you need WEP enabled. I would leave WEP on however, it minimises the chances of people leaching bandwidth off of you- it can be cracked but the crack takes atleast an hour to recover the encryption key, and checking your access point's logs occasionally would probably enable you to discover if anyone was keen enough to wait that long.
