    Don't forget having a KMS infrastructure where every single machine in the company can contact an activation server every 180 days. Yes, one can use MAK type of keying, but if a box needs a reinstall, that means one has to burn another install key.

    In a previous life, I've encountered cases with legacy apps as well, where the client was 32 bit... but just would not work on Windows 7 for love or money. I ended up having to use virtual machines running XP for the dedicated program.

    Of course, there is the server infrastructure Windows 7 requires. New GPOs, more disk space for updates for WSUS, more PXE images, etc.

    So, a move to Windows 7 (or a major OS update for the clients for that matter) isn't something to be taken lightly in a company, because one mistake can trash hundreds to tens of thousands of desktops. At minimum, it requires a test lab and running upgrades to see what ugly issues will rear their heads.

  2. Other than Windows 7 (or for that matter 8.1) being an OS made to address security concerns for 2014 as opposed to having security strapped onto an OS made in 2001, for a lot of users, XP is good enough.

    Other than being newer, there just isn't much in Windows 7 or newer that is groundbreaking and would get users to move to it. Moving from ME to XP was an obvious improvement, but from a user's perspective, XP to Windows 8.1 just doesn't bring that much with it for their sake, other than it being easier to reinstall the OS [1].

    [1]: I wouldn't want to reinstall the OS from those options, just because if it is due to malware, the OS image can get tampered with. Hardware failure likely means a complete reinstall from OS media. The only case I see that makes a "reset" something as an option would be Registry corruption... and that is very uncommon these days.

An occasional scrub of the pool will catch any bit rot that might happen, and if one adds SSD, the filesystem will know to autotier it.

    Of course, we have seen this before. Ages ago, there was a push to move to software RAID from hardware controllers back around the turn of the century. However, a few years after that, it was back to hardware RAID controllers and the software just using it as a plain disk.

    [1]: My only complaint about Linux in general is that it doesn't have an enterprise-grade modern filesystem. btrfs is still not finalized yet (and it can't be booted from), and a true enterprise grade filesystem merges the LVM and the FS to be able to catch bitrot and file corruption via CRCs.

    What I see that makes Windows 8.1 [1] an upgrade isn't the UI changes. There are some nice under the hood features. The annoying wait for chkdsk to finish is gone, because it can be run while a volume is online to find broken index nodes. BitLocker can be used without a TPM to ask for a password, similar to how TrueCrypt functions on boot. It is easier to blank out a PC completely if handing it to someone else ("reset" option, choose to blank the drives, let it erase and reinstall,) Windows Store apps function in their own jailed space, which helps security, and so on. None of these features are really what a lot of users care about, but with a third party program like Classic Shell, W8 or W8.1 can be made decently usable.

    So, all things being equal, and if Classic Shell does make up for the new UI quirks, moving to W8.1 is a good thing to do just due to the fact that it is coded for more recent threats. This isn't as bad as the XP days where an OS made in 2001 is trying to handle threats in 2014, but using an OS with security designed for more recent threats as opposed to having it strapped on can be the difference between reading about the latest version of Cryptolocker going around versus having to pay the Cryptolocker guys several BitCoins.

    I've wondered why PC makers don't get out of the "good enough" mold and start working on addressing user concerns, especially in security. Preferably in a way other than demanding people move to a restricted, locked down platform. Some suggestions:

    Built in hypervisor and AV software that can run as a separate VM, pause the Windows partition, do a RAM image scan of that, then go on. Rootkits can hide from the OS, but they have to show themselves somehow, and something that sits outside the memory space that can't be touched would catch them sooner or later. It isn't a 100% magic bullet, but it can help catch things and require fewer signatures (mainly heuristics) as opposed to the hundreds of thousands needed for conventional AV signature detection. The hypervisor and virus scanning VM can also scan the disk image for stuff that is hidden from the OS. Not perfect, but this is only a tool in some of the highest end enterprises.

    Some "mini-SAN" features on the disk controller. Snapshots, a LVM tool, disk encryption on the controller level, the ability to save snapshots to an external hard disk as backups regardless of what OS is on the drives, and so on.

    A read-only flash disk with the recovery media burned on it. This way, when someone has a corrupt disk, the recovery volume on the same disk is also infected, there is a way to completely zero out the drive and install a clean OS from scratch without having to repurchase Windows or other OS media. This isn't new. There were Tandy with built in MS-DOS in ROM.

    A hypervisor where one can easily clone and switch between Windows installations. That way, one's general Web browsing is on one VM, banking on another, gaming on still another... and all the VMs use a deduplicated LUN so creating a new Windows instance takes up a small amount of space. Of course, updates can be handled by a WSUS-like mechanism so only one set would need to be downloaded for all the VMs.

    Built in 3G/4G/LTE/CDMA/GSM connection that can be turned off and locked down via BIOS or a switch. The onboard hypervisor would offer it as a vSwitch, or perhaps even with router/firewall functionality, so the inner OS is well protected. This way, there is always some connectivity to the Internet, barring areas with zero cellular service.

    Thunderbolt, so one can use tape drives and other high I/O stuff. USB 3 is OK, but it can't drive a modern tape drive without shoe-shining.

    IMHO, what we have seen in the CryptoLocker game is just the beginning. We have close to a perfect storm here -- Bitcoin being a currency that is easy to use no matter where one is, provided Internet access is obtainable [1]. For the most part, security is a joke because people/businesses either don't care, view it as having no ROI, or just view it will happen to "the other guy." Unlike incoming Internet connections which will get stopped by at the minimum, a perimeter firewall, the untrusted code on an external web page makes it well into the depths of a company. Most companies might have something to block the nudie pics, or use a device to force all SSL transactions to go through a transparent listening/MITM proxy (BlueCoat for example), but usually that is the extent of how far they go. Blocking suspect malware IP addresses tends to be rare unless a company is on top of their game.

    With this in mind, it might take a single browser or add-on weakness for an organization to get malware deployed. Since most Web browsers run as the user, it means the malware usually ends up with a full unlimited user context. Barring Web based malware, there is always the good old fashioned "foo.pdf .exe" Trojan.

    CryptoLocker is just version 2.0 (v1.0 being the early ransomware with an easily factored key being the same, or a flimsy encryption algorithm.)

    I can see RansomWare 3.0, if it manages to get root/Administrator authority, installing a low level driver. It will encrypt files, and backup programs will back up the encrypted stuff (a la Microsoft's EFS), but the user won't know because the driver will allow reading/writing for a period of time. Then, after a cutoff date, the private key is wiped, and the driver is dropped from the system. This not just encrypts the files that are accessible, but it also ensures that recent backups will be completely and utterly useless for restores. The private key can also just never be stored on disk, and quietly fetched from the malware owner's website every time the machine reboots.

    To boot, the software will detect where the software is installed and base the ransom of where it is located. If a police station, the demand to release all prisoners in the county jail can be made. A government office means that the criminals can demand someone be fired. At the extreme, if the files locked up are valuable enough, the organization can demand an execution of someone they don't like.

    Now the question -- how can we prevent this. Well, it costs money. Someone can invent software that can check backups and detect files that were encrypted, but in reality, it means RansomWare 3.1 will just encrypt the file in a valid .doc, .xls, or other format. It will take keeping a round of backups for a long time. It will take better heuristics so an AV utility [2] can detect some process fiddling over time with files and stop it. It might even require machines be rebooted from offline media and scanned in that condition, and instead of a scan looking for anything out of the ordinary, the reverse happening -- a scan looking for anything that isn't a signed binary or valid Registry entry in order to find rootkits (assuming ones that just don't exist in RAM.) It might even require a new computer architecture with a hypervisor that can suspend the entire machine, then scan the RAM image and the disk every so often.

    I agree with you there. The first thing is to consider the threat model. Is it better to forget some passwords and lose access for good as opposed to having them be exposed if one's password utility gets compromised?

    I look at what threats I have. Theft of a device is a big one. Compromise of a cloud account is another biggie. Theft of a device and demands for access to passwords is a third, because criminals are wising up to the fact that coercing an unlock code can provide more usable things to sell.

    The solution to this would be a program where every instance had its own private key. The central file would be stored on a cloud provider. When a new device is added, the public key from the new device would be manually copied to another device with access, and the device with access would add a decryption key entry to the encrypted file. When a device is removed, the whole file is decrypted, re-encrypted with a new master key, and a keylist [1] added of what public keys (that belong to devices) added.

    Said program would function similar TrueCrypt where there are different users and passwords to access data segments of the file. So, one can hand over the password for a decoy user and be done with it. Since the program would randomly add "chaff", there is no way to tell if the data is garbage or other encrypted items. (this is taken from PhonebookFS's design.)

    The result is decent security and ease of use. If one trusted the device's security, the passphrase to unlock things could be turned into a PIN, all the while, there are no brute-forcable passwords that an attacker could easily break with the file stored on the cloud provider. The downside with trusting the device's security (iOS's KeyChain for example) is that that can be compromised, but that is a risk someone should calculate.

    [1]: The keylist is just the master key encrypted to a device's public key, so 10 devices would have ten separate entries, each device able to independently fetch and decode the file's contents. The reason for the complete decryption and re-encryption is to ensure that a device that had access to the master key would no longer possess that.
