In the case of the Personnel files, Alice s administrators set a DACL on the folders and files that she needs to work with to explicitly define the extent (Read) or limits (not Create or Write) of access that she as an individual or member of a security group has to those files. Every computer and service on the network also has a security context that governs the resources that it is permitted to access and the actions that it is permitted to take.

WLAN to communicate with each other. The IEEE 802.11 standard for WLANs defines speeds of 1 and 2 Mbps. Clearly, the 802.11 standard is rather slow. However, the new IEEE standard for WLAN networking is 802.11b, which defines transfer rates of up to 11 Mbps using the 2.4 GHz Industrial, Scientific, and Medical (ISM) frequency band. The 802.11b standard is currently the most popular standard, giving you speeds comparable to a typical Ethernet network. IEEE 802.11a, a newer standard that provides bit rates of up to 54 Mbps using the 5 GHz frequency band, is now available as well.

Access control information is first written to an object s security descriptor when the object is created. Then, when a user tries to perform an action with the object, the operating system examines the object s security descriptor to determine whether the user is allowed to do what the user wants to do.

communications within a single metropolitan area. For example, a WMAN in New York City could let a company connect wirelessly to its three offices located around the city. The IEEE 802.16 standard, which defines the technologies that can be used in WMANs, is still under development. WMANs can use radio waves, infrared light, or even laser connections to transfer data between locations.

The information that is included in a security descriptor depends on the type of object in question and how it was created. In general, security descriptors can include the following information:

Which user owns the object Which users and groups are allowed or denied access to the object Which users and groups access to the object must be audited

This information can later be modified. In both cases, the information that goes into a security descriptor is supplied by one of the following:

are separated over wide geographic areas. For example, if your company has offices in New York, Seattle, and Dallas, a WWAN could be used to wirelessly connect the different WAN network segments. WWAN technologies involve the use of satellite communications maintained by service providers and also use the same technologies as cellular phones and wireless PDAs. Common technologies include Global System for Mobile Communications (GSM), Cellular Digital Packet Data (CDPD), and Code Division Multiple Access (CDMA).

5: Using Rapid Application Development Tools with Visual C# 2008

When a subject creates a new object, it can assign the object a security descriptor. If the subject does not assign a security descriptor, the operating system uses access control information inherited from the parent object to create one. If no information is available to inherit, the operating system uses default access control information provided by the object manager for the particular type of object that the subject wants to create. After an object is created, the object s owner or any user who has the permission to change permissions can change information in the object s security descriptor. The owner can assign the permission to change permissions to other users. Changes can also come from the parent object when that object s owner modifies its security descriptor. This process is called inheritance. Every time the security descriptor on a container object is changed, the object manager propagates any changes marked as inheritable to all objects in the container, as long as those objects are not protected. For more information about managing inheritance, see Modifying Inheritance of Permissions later in this chapter.

Managing security groups, ACLs, and security settings requires careful planning. Developing an access control plan can help to prevent basic security problems, such as inadequately protected resources, users granted greater rights and permissions than they need to do their jobs, or ad hoc security configurations that are not based on a well-thought-out, manageable security plan. Ad hoc security management might provide adequate protection for small organizations, but it will quickly break down as the organization grows.
