Write access windows

Employees armed with a USB drive can easily copy or move data from the office computer to their removable drives. Another big concern is the virus or Trojan which may accidentally creep in to the office computer because someone plugged in a USB drive and tried to run or install a software application. To deal with unwanted virus or Trojans in USB drives, you should disable the autorun when any removable drive is plugged into the computer.

Write access windows

There is no permission in these systems which would prevent a user from reading a file. OpenVMS also uses a permission scheme similar to that of Unix, but more complex.

The categories are not mutually disjoint: World includes Group which in turn includes Owner. The System category independently includes system users similar to superusers in Unix. Mac OS X versions Mac OS X, beginning with version These scopes are known as user, group, and others.

When a file is created on a Unix-like system, its permissions are restricted by the umask of the process that created it. Classes[ edit ] Files and directories are owned by a user. Distinct permissions apply to the owner. Distinct permissions apply to others.

The effective permissions are determined based on the first class the user falls within in the order of user, group then others. For example, the user who is the owner of the file will have the permissions given to the user class regardless of the permissions assigned to the group class or others class.

Modes Unix Unix-like systems implement three specific permissions that apply to each class: The read permission grants the ability to read a file. When set for a directory, this permission grants the ability to read the names of files in the directory, but not to find out any further information about them such as contents, file type, size, ownership, permissions.

The write permission grants the ability to modify a file.

When set for a directory, this permission grants the ability to modify entries in the directory. This includes creating files, deleting files, and renaming files.

The execute permission grants the ability to execute a file. This permission must be set for executable programs, in order to allow the operating system to run them. When set for a directory, the execute permission is interpreted as the search permission: The effect of setting the permissions on a directory, rather than a file, is "one of the most frequently misunderstood file permission issues".

Unlike ACL-based systems, permissions on Unix-like systems are not inherited. Files created within a directory do not necessarily have the same permissions as that directory. Changing permission behavior with setuid, setgid, and sticky bits[ edit ] Unix-like systems typically employ three additional modes.

These are actually attributes but are referred to as permissions or modes. These special modes are for a file or directory overall, not by a class, though in the symbolic notation see below the setuid bit is set in the triad for the user, the setgid bit is set in the triad for the group and the sticky bit is set in the triad for others.

When a file with setuid is executed, the resulting process will assume the effective user ID given to the owner class. This enables users to be treated temporarily as root or another user. When a file with setgid is executed, the resulting process will assume the group ID given to the group class.

When setgid is applied to a directory, new files and directories created under that directory will inherit their group from that directory. Default behaviour is to use the primary group of the effective user when setting the group of new files and directories, except on BSD-derived systems which behave as though the setgid bit is always set on all directories See Setuid.

Also known as the Text mode. The classical behaviour of the sticky bit on executable files has been to encourage the kernel to retain the resulting process image in memory beyond termination; however such use of the sticky bit is now restricted to only a minority of unix-like operating systems HP-UX and UnixWare.Windows 7 network.
