1How to Mount ISO Files for Scanning 2=================================== 3 4Dependency-Check can be used as one of your tools for vetting software 5distributed via an [ISO image](https://en.wikipedia.org/wiki/ISO_image). (See 6[File Type Analyzers](../analyzers/) for a list of what types of artifacts 7Dependency-Check is capable of scanning.) These disk image files are not a standard archive format, however. Tools must be used that can interpret the contained file system. As will be shown below, Linux, Mac OS X, and recent versions of Windows can be used to mount the image's file system, which can 8then be scanned by Dependency-Check. 9 10ISO images are named for the fact that they nearly always contain one of a 11pair of international file system standards published by 12[ISO](http://www.iso.org/): [ISO 9660](https://en.wikipedia.org/wiki/ISO_9660) 13and ISO/IEC 13346, a.k.a. [UDF](https://en.wikipedia.org/wiki/Universal_Disk_Format). Other types of disk images (e.g., 14[VHD](https://en.wikipedia.org/wiki/VHD_%28file_format%29)) are outside the 15scope of this article, though the ideas presented here may likely be 16successfully applied. 17 18Linux 19----- 20 21Assume you've downloaded an ISO image called `foo.iso`, and you want to mount 22it at /mnt/foo. (Why /mnt? See the 23[Filesystem Hierarchy Standard](http://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch03s12.html).) 24First make sure that the mount point exists using `mkdir /mnt/foo`. Then, the 25[mount](http://linux.die.net/man/8/mount) command *must be run with root 26privileges*. On Debian and Ubuntu Linux, this is accomplished by prefacing the 27command with `sudo`. 28 29```sh 30$ sudo mount -o loop foo.iso /mnt/foo 31``` 32 33Next, you can use Dependency-Check's [command line tool](dependency-check-cli/) 34to scan the mount point. When you are finished, run the 35[umount](http://linux.die.net/man/8/umount) command with root privileges: 36 37```sh 38$ sudo umount -d /mnt/foo 39``` 40 41This will unmount the file system, and detach the loop device. 42 43Mac OS X 44-------- 45 46### Using the GUI 47 48Simply double-click on the image file in Mac OS X Finder. 49 50### Using a Terminal Window 51 52Use the [hdiutil](https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/hdiutil.1.html) 53command. 54 55```sh 56$ hdiutil attach foo.iso 57``` 58 59The output will show the `/dev` entry assigned as well as the mount point, 60which is where you may now read the files in the image's file system. 61 62To detach: 63 64```sh 65$ hdiutil detach foo.iso 66``` 67 68Windows 69------- 70 71Windows 8 and later versions support mounting ISO images as a virtual drive. 72 73### Using the GUI 74 751. In *File Explorer*, right-click on "foo.iso". 762. Select "Mount" 77 78File Explorer then redirects to showing the files on your virtual drive. You can then use the [command line tool](dependency-check-cli/) to scan the 79virtual drive. When finished, "Windows-E" will open File Explorer showing the various drives on your computer. To eject the virtual drive: 80 811. Right-click on the virtual drive. 822. Select "Eject" 83 84### Using PowerShell 85 86To mount, use the [Mount-DiskImage](https://technet.microsoft.com/en-us/%5Clibrary/Hh848706%28v=WPS.630%29.aspx) 87cmdlet: 88 89```posh 90$ Mount-DiskImage -ImagePath C:\Full\Path\to\foo.iso 91``` 92 93To view all drives (and find your virtual drive), use the 94[Get-PSDrive](https://technet.microsoft.com/en-us/library/Hh849796.aspx) 95cmdlet: 96 97```posh 98$ Get-PSDrive -PSProvider 'FileSystem' 99``` 100 101To dismount, use the [Dismount-DiskImage](https://technet.microsoft.com/en-us/library/hh848693%28v=wps.630%29.aspx) 102cmdlet: 103 104```posh 105$ Dismount-DiskImage -ImagePath C:\Full\Path\to\file.iso 106``` 107 108### Windows 7 109 110Third-party tools exist that can be used to mount ISO images. Without such 111tools, it is still possible to burn the ISO image to physical media, and scan 112the media: 113 1141. Right-click on "foo.iso" 1152. Select "Windows Disc Image Burner" 1163. Follow the instructions to burn the image. 117 118### Windows Vista 119 120Just as with Windows 7, you will need a third-party tool to mount an ISO 121image. You will also need a third-party tool to burn the image to media. 122Many machines are shipped with such a tool included.
