Encrypt the files inside VMFS

Yes, I know the facets of encryption-Interior-VMware discussed here many times, but I think that my request/idea differs slightly from the other applications, so if you lend me your ear for a moment...

For example, say I have a sensitive security VM that needs to be turned on for a few hours once from time to time, maybe twice a year, for example. The rest of the year when this VM is powered down, I need to protect his content even of other admins vCenter. One option is that I need to SCP the VMDK (s) off storage VMFS and keep that he secured/encrypted on another external when not in service and re - copy and reconfigure system whenever I need to start it up.

But my idea and the question is: is there a way I could leave the VMKD (s) in place, inside our VMFS on SAN highly redundant, but encrypt files in place (for example with TrueCrypt, PGP or other) when not actively in use? So whenever I needed to start the virtual machine I must first decipher the VMDK (s), but after discontinuation of the VM and rechiffre files, they are still saved (in encrypted form), HA/DR-ready and all that.

It seems that this could be easier at the time of the 'thick' hypervisor, when he might have to compile TrueCrypt in ESX. Now with ESXi, perhaps it is possible to mount the VMFS LUNS from an external system and encrypt or decrypt from there.

I guess another question is then if ESX and vCenter would try to access the VMDK in his State in offline mode and choke on the encrypted file unreadable... in which case, I would probably have yet to remove the configuration of the virtual machine after each use and reconfigure (or re - import the VMX) whenever the virtual machine should turn on again who loses a portion of the benefits to keep the file in the VMFS.

Your thoughts?

Why not use TrueCrypt, etc. to the INSIDE of the virtual machine, and encrypt the content of the VMDK, rather than the VMDK itself.  At startup, the virtual machine would require to enter your password to continue.

This protects this virtual machine of the other admins vCenter and solves the problem of connection the VMDK to another virtual machine.

Maybe I'm missing something?

    Hi TeejayR,

    Thanks for posting your question in the Microsoft Community Forums.

    Please answer this question to get more clarity on this issue.

    • What software do you use to encrypt the file?

    You can use BitLocker Drive encryption to protect your files on a disc. BitLocker can help the hacks to access the files on the system, that they rely on to discover your password, or to access your drive by physically removing from your PC and install it in another. You can always connect to Windows and use your files as you normally would.

  • Open the file inside the app

    Hello

    I am an old user of Windows and new to Mac, so this is probably a stupid question. But I wonder how the files in an application package can be opened using the file > open dialog box.

    I installed a 'Scid vs Mac' chess program and need to open a chess database file that is stored in the ScidvsMac application package.

    I know that you can view the contents of the package in the Finder. But Scid does not support drag & drop for databases of chess, so I need to open the database with the file open dialog box? But I've not been fined of any opportunity to look inside the package. So, how you go through to access a file within the application package in the Applications folder?

    Thank you

    Use the utility called pacifist. However, I do not know if will do what you think you need to do. Once inside a package by using the Finder, you should be able to find the database and replace using drag and drop.

  • How to export a layout Epub fixed without encrypting the files of fonts?

    When I export to a fixed provision ePub and you later want to convert it to a Kindle format fonts in the /META-INF/encryption.xml file are not retrieved correctly. How can I tell InDesign do not encrypt the font files and incorporate instead?

    The CSS has nothing to do with encryption. If your font (ttf or otf) is applied in InDesign, the fontface markup will be automatically generated by InDesign and this markup does not matter whether or not the police is encrypted/hidden.

    If you have used fonts under SIL Open Font License (OFL) license (Linotype, FontFont,... are not lic. under SIL!), you can extract the contents of your ePub, replace the font files included here, with the original font files and delete the encryption.xml file. Then you can convert it to Kindle. Of workaround does not work with typekit, skyfonts or services because you don't have access to the original font files. Over 99% of commercial fonts you cannot replace fonts epub with versions not encrypted, so be careful here. Please take a look first at the following discussion to see what might be allowed to do or not because you often have restrictions on moving or commercial license font embedding: A Solution to fonts...

  • I have two different file names, but the files inside of them are exactly the same

    Hi all

    I was running a double Finder folder.  I realize that in my Directory user (c:\users\myname) there are a few paths to the same folder, but referred to by different names.  One of them is C:\users\myname\AppData\Local\ the other folder is C; \users\myname\Local Settings.  Both of these 'files' link to the same files on the hard drive.  The double file Finder think that these files are duplicated because they seem to be in different folders, but they are in fact the same files singled twice.  The C:\users\myname\Local settings directory has a symbol that looks like a shortcut, but it does not behave as such.  There is no way to remove it without deleting the file in the other folder.

    Is a problem in the file system, or is it simply one of the oddities that I should just ignore?

    Thanks for any help

  • Access to the file inside .cod with widgets

    Hi, I'm changing my app to help icon

    The Images/Logo.png resource could not be found because it is not found in they config.xml please check the element in the config.xml file.

    I tried to put and all sorts of variations but I send an error message during compilation.

    Does anyone know how to access this path, he assumes must be inserted in the file of the Cod.

    Hi, thanks for the idea, yes I've tried local written: / / / in front of Images/Logo.png, but he sent me an error, and I tried to put local: / / / in my list of white with the same result. This morning, after a bad night and with 500ml of coffee in my vain, I found the solution.

    1 - write the full path: local:///Images/Logo.png

    2 - Add the full path even in my whitelist

    And it works now. In my case it question if I allowed subdomains in local: / / /, I'd even add the full path in the white list

  • Get the duration of all the files inside a directory mp3

    Hi all

    I'm working on a little project with swing. Because I need an MP3 inside my swing application, I found a solution really good with JavaFX 2. I never worked with JavaFX, to this effect, it seems a bit strange on some parts.
    Anyway.

    I created a button on my request and as soon as someone clicks on this button, the application should scan recursively a directory of mp3 files and store information of artist, title and track length in a database.

    The mp3 player I created is based on the example on this page:
    http://www.java2s.com/code/Java/JavaFX/Mp3playerwithmetadataviewandcontrolpanel.htm

    I understand the source of most of the regions, but some behaivors are not really clear for me. My thoughts to get the full length of the mp3 file has been

    media.getDuration
    or
    mediaplayer.getTotalDuration

    but the two results are NaN values if I call. toMillis();

    Instead I need to create a listener (why?)
    private class TotalDurationListener implements InvalidationListener {
        @Override
        public void invalidated(Observable observable) {
          final MediaPlayer mediaPlayer = songModel.getMediaPlayer();
          final Duration totalDuration = mediaPlayer.getTotalDuration();
          totalDurationLabel.setText(formatDuration(totalDuration));
        }
      }
    and register for this listening port on the mediaplayer
    mp.totalDurationProperty().addListener(new TotalDurationListener());
    I can image that the mediaplayer can "host" several objects somewho media and the listener is called as soon as a new media will be added to the mediaplayer in order
    the calculation of the total time.

    When this listener is exactly called and is there any other way to get the total length of the mp3 file?

    The other question is why do I need a headset for the metadata to be changed in order to get the metadata?
    media.getMetadata().addListener(new MapChangeListener<String, Object>()
    Why can't I call something like
    media.getMetadata ()-> returns a map full?

    The problem of metadata is not included in the above example.


    Sorry for my English, but I hope that everyone can understand the question.

    Many greetings,
    Hauke

    The class nature of the media is that it accesses it asynchronously. This means that when you create an instance of it and then immediately question him, the data that you might want to not available yet. It's all in the Javadoc, see the doc for the media:

    The media information are obtained from asynchronously and are therefore not necessarily available immediately after the instantiation of the class. However, all the information should be available if the instance has been attached to a MediaPlayer and this player is passed to the status of MediaPlayer.Status.READY

    So you can engage the media in a MediaPlayer and then wait until he goes to the READY State and then read the length of the media.

    On your 2nd question, getMetadata() turns over a card. Loop just through him:

      for(Map.Entry entry : media.getMetadata()) {
        // etc
      }
    

    However, the same restrictions apply as with the media - you'll probably have to wait before information is available - that's why the listener approach works because it will inform you as soon as information is added to the map.

    Hi all

    -I'm a bit confused abt encryption of image, audio, video, files that I will store in a single folder on SD card.

    -I want to encrypt this folder so that no one can consult data except my app.

    -J' searched a lot but I couldn't find the pefect solution but I find something that may be correct.

    -I can't convert the entire file in the array of bytes so I wil convert all the data inside the file to a byte array then using crypto api I'll pass this array of bytes.

    I want the suggestion. This is the right way to encrypt the folder on SD card?

    Thank you...

    You can encrypt the files, there is no such thing as an encypted folder.
    API to encrypt/decrypt the byte [] to a file using the Cryptography is the correct way, Yes.

  • Properties of the file means nothing?

    I'm learning to iTunes.  I got rid of my iPod years and promised to never go back.

    Yet, I find myself in the situation where I need to learn it again.

    Just try to understand a few issues here.

    (1) if I look at the properties of my file (Windows), I can see album, genre (?), etc.  I can also change this information.  I need so that I can create playlists based on some information.   If I change this information in the properties of the file Windows, iTunes is updating new information?

    (2) when iTunes imports all the music on my computer, it copies it to a new location?  For example, if I download an album to my office, all the files are in a folder Album1.  Can I synchronize files in iTunes (or drag and drop into iTunes) can I go back to delete the original folder of Album1 off my desktop computer?

    Thank you

    1. N ° iTunes will automatically detect changes to external metadata. These will be picked up if iTunes because of reading the label, for example during playback. If you use iTunes, using iTunes. I have a script called UpdateTagInfo if you really want to change externally and then force iTunes to notice.
    2. It depends on where the files (inside or outside the designated media folder) and your choice for the advanced preference, copy the files in the folder when adding to library media. My recommendation is to leave this option. A free iTunes content library is much easier to backup and you move.
