Password protect a NetInstall image

How can I password protect a netinstall image? I don't want just any user netbooting their computer and wiping the local drive with a new image.
Thanks.

Take a look at Mike Bombich's NetRestore -- http://www.bombich.com/software/netrestore.html
One of the things you can do with NetRestore is connect it to a database of "authorized" computers that will restore. All others are given an error and have no source options for wiping their hard drive.

How can I make a password protected encrypted sparse image?

How can I make a password protected encrypted sparse image?
Doing what worked in 2006 does not produce password protection even though I have typed one in and re-entered it as requested. Clicking on the Disk image opens it without asking for the password. I am stumped. Many thanks.

Yeah, nobody does. They should put up a custom password save box when you make an encrypted disk image that explains what will happen if you store the password in the keychain. In the current "how-to" article, they mention it, though: How to create a password-protected (encrypted) disk image - Apple Support

Open An Encrypted, Password Protected Saprsebundle Disk Image With iPhone?

Is it possible to open an encrypted, password protected sparsebundle disk image using an iPhone/iPad/iPod Touch that is stored on a NAS drive connected to an AirPort Extreme Base Station?
If so, how do I do it?
If not, would you be able to explain why not?
Thanks, Alex

Hi Robert,
> Once you through a sudo in there, you lose the option
to have a regular user
   That's not really true. Sudo is one of the most flexible commands around and not only can a regular user use it but they can use it without a password. Mind you I'm not suggesting that you make all users admins; you can specify both of these privileges for this command only. All you have to do is to put a line like the following in your /etc/sudoers file. (with sudo visudo of course)
ALL ALL = NOPASSWD: /usr/bin/hdiutil create -encryption -certificate*-stdinpass -type SPARSE -fs "HFS+" -volname-size
I've included wildcards so that the cert file, volume name, size and image are arbitrary but the others must be in the user's command to qualify. I realize that you'll want different options to use FileVault certs but I don't know how to do that so I used your original example as my example.
   Of course it wouldn't be that easy for your lusers to get all of those options correct so the next thing you do is to wrap the command, with it's sudo preface, in a shell script that parses the cert file, volume name, size and image from the options the user passes to the script and puts those into the command with the right syntax. If you want to get really fancy, the script could prompt the user for any arguments that were omitted. Your lusers will think that you created this really cool command and never know that sudo was involved.

Password-protected Sparse Disk Image Bundle remembered after eject

I use password-protected Sparse Disk Image Bundles to protect some files. Every now and then, when I open the image, it doesn't ask me for the password and opens immediately.
At first, I thought I may have inadvertantly agreed to save the password in Keychains. But that is not the case. After running some tests, I noticed it may take up to 3 ejects before it asks me for the password again. It seems to happen more when I modify files in the disk image, but not when I simply read files. I suspect it is not completely unmounting the image.
This is potentially a security issue. Any suggestion on what I can do short of re-ejecting images until it asks for a password again?

You may have successfully increased the sparsebundle's potential capacity while failing to resize the contained partition. That seems to be what happened when I tried this myself. A resized sparsebundle containing the same files would not occupy much more space on disk than it did before.
*Provided you have a backup*, you could try the following:
Remount the image, then run Disk Utility and select the .sparsebundle (non-indented icon) in the left pane. Click on the Partition tab, and then see if you can pull down the lower right corner of the disk image partition to increase its size. If you can, then drag it to the bottom and click Apply.
Again don't try this without a backup. It may not be worth doing in any event - it's easy enough just to make a new, bigger sparsebundle and copy your stuff over.

Is there a way to password protect the NetInstall process?

I could not find this topic through the search function (correct me if I´m wrong) so I´m starting a new one here.
Is there a way to exclude users from accidentally clicking their way through the NetInstall process? In specific I would like to password protect it, without using third-party-applications if possible.

Hmm.. ..for me alone doing NetInstalls, this would not be a problem, but I need to ensure relatively easy Install procedures for less trained personal (Like start with "N", click OK, enter password, off you go..).
Has anyone experimented with modifying the System Restore Package inside the NetInstall .dmg? I´m not that experienced with .pkgs, but might this be a possible way? Some preinstall-script doing LDAP-authentification?
Or is there a way to add MAC-addresses to the Server Admin allow list via a script? Then I could configure one server as a "gate" with a NetBoot Set containing an account allowing the computer to start of a second NetInstall-only-server through a login script...

Password Protect folders (non sparse disk image)

So there are a collection of files I have protected on my computer using the disk utility method that everyone asking this question uses. I am curious to know if there is any other way of doing it. I want to password protect a folder within this protected disk image just becuase i feel like being extra sneaky and careful at the moment. I mean I could just use another sparse disk image inside the original and use two different passwords but I'm trying to be creative and that could get confusing. Does anyone know of a way to password protect a folder or file without using the disk utility method in Lion? Even if it requires third party stuff

From your earlier posts I gather that you would like to have a high level of security for your data. If an encrypted folder does not do the job for you, you may want to consider FileVault. However, if you use FileVault there are to very important measures you must take: 1) You must remember your password. If you lose or forget your password you will lose aceess to your data permanently. There is no way around it. 2) You must leave adequate space to be able to disable FileVault, should you every need to do so. The encrypted sparseimage requires almost double the size of the image to be able to be expanded.

Password protect a file beyond disk image?

Hi,
I've made a password protected disk image file, but once it's opened the file can be opened without a password every time.
Is there a way to password-protect a file, so that every time you try to open it, it requires a password? (like the way you can encrypt a PDF...)
Thanks!

Password Protected Sparse Image Has No Password Anymore

After installing Mavericks a password protected sparse disk image has no password anymore, I just click the image and the content opens. It used to ask for a password with Mountain Lion... any help?

Is there a way to password protect files?

Okay, so I want to make a personal file where I store personal information like receipts, photos, etc. Is there a way that I can protect the file with a password so nobody can get access to it?

Hi marty,
The best way to encrypt files is to make a encrypted disk image. You can find more information on encrypted disk images in Knowledge Base Document #107333 on How to create a password-protected (encrypted) disk image.
I don't suggest using FileVault because in the past I have noticed that it can cause complications. Even though it runs smoother since Mac OS X 10.4 (Tiger); it still isn't full proof.

Password Protect a Folder

Hello,
is there a way to password protect a folder?
THX
Ben

Almost. You can open "Disk Utility", then File > New > Disk Image From Folder. Choose the Folder you want to "password protect", then click Image. In the next dialog box, choose one of the two types of encryption (not none!). Also choose a name for the disk image, and click "Save". You will be prompted for a password for the disk image. Now you have made a copy of the Folder you wanted to password protect, and it will have a dmg extension. To eliminate the original Folder, drag it to the Trash and then "Secure Erase" the Trash. To use the new password-protected disk image, double click it and type in your password. In fact, you probably won't need to remember the password for the disk image itself, because it will be stored in your keychain. Rather you will need to type in your usual login password so that disk utility can retrieve the image's password from your keychain.
Two comments:
1. You may not want to secure erase the original folder until you are sure the disk image works!
2. I don't have a lot of experience with this, so I can't promise the disk image will be writable, and not read-only.

How to creat a Password Protected Folder

Hi
I was wondering how do I create a single folder that contains all of my passwords (Banking ...etc) that only I have access to - I would like to password protect this foder and if possible have the information inside encripted.
I was looking into security vault - but I'm afraid it encripts all the folders on my Mac. I just want to create a single folder - everything else should be as it was.
Any help is greatly appreciated
Thanks

An easy way to password-protect certain folders
To password protect a specific folder in any version of OS X, if you're an administrator, simply change the permissions in the "Get Info" box so that the folder is owned by the system. You'll be prompted for a password. To access the folder again, just change the ownership back - and it will require a password to be made accessible.
Secret Folder lets you conceal a folder and its contents.

How to delete a password-protected folder?

If I use disk utility to create a password-protected folder (disk image) on my Mac, could someone else easily drag that folder to the trash and delete it?
Or do you need the password to delete a password-protected folder?

The password only keeps them from opening the folder without the password. If they have access to the account, then they have the same abilities as you to install or delete files or folders.
If you don't want someone messing with your data, then they should have their own account on the computer and log out of yours when your done. You can create an account each of the other family members, or create one account for the rest of the family to use and one for you. That way you can restrict what they can and can't do on the computer such as installing applications, etc.

Password-protected .dmg file "forgets" it is protected

So, on my external USB hard disk I had created two password-protected ".dmg" disc images. Both functioned normally for about 2 months. Then, suddenly, one of the two images now opens without asking for its password (the other file remains protected). What happened?
I tried ejecting the virtual disc and double-clicking on the .dmg file again, and each time the disc mounted with no password required. I ejected the external hard disk, unplugged the USB connector, replugged it, and the same thing happens.
It looks as though I need to replace this .dmg file with another password-protected one, but how long will that last?

Hmmmm, Open Console in Applications>Utilities & see if there are any clues or repeating messages when trying to open Keychain Access.
Maybe this first...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

Password protect netinstall starting up

Hi,
I currently manage an educational lab of 40+ computers, all connected to an Xserve. What we have been finding is that students have discovered something fun happens when you press and hold N when starting up (which finds out netinstall image on the server). The problem is that 1) if the students re-image the machiene by just 'clicking through', we dont know about it so the post-image tasks aren't completed and 2) through the options menu they can change the Open Firmware password and the Admin password. Can anybody suggest a way to stop this from happening i.e. password protection before it even gets to the netinstall setup?
Thanks

Trying to create a password protected disk image in 10.8.4

Trying to create a password protected disk image in 10.8.4. I follow steps in Apple:Support but I get an error saying "Resource busy"?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.
