Network Management and Systems Administration - Essay Example

Network Management and Systems Administration Introduction The ials under application protocols help in understanding networkmanagement. This is done through the different layers of networking protocols. Networks can involve; enterprise WLAN, fixed switching, modular switching, and enterprise high capacity switch routers. The network system administration involves the procedure of ensuring, reliability, predictability, and security of computing workstations, networks, and services. The application protocols show how URL protocols can be developed.

This can be done by invoking another application in handling the custom protocol. This is done by registering the accessible application as a URL handler. After launching the application successfully, command line parameters can be used in getting the URL that launched it (Farrel, 2004). This is possible for, the protocols run within Windows Explorer and Windows Internet Explorer by using the Run command. These applications for URL protocols should have a mechanism of acting on malicious data.

This is so because application handlers can get data from un-trusted sources. The parameters and URL might have malicious data that can interfere with handling the data application.Application protocols are simple. They enable the browser to launch a program. The browser can include; PDF reader or word. This is done by momentary the requested URL to the program. The examples of application protocols include; onenote, mailto, and news protocols. The simplicity of the application protocols is shown by the protocol scheme that they are associated.

For example onenote protocol is associated in the registry by a local installed application like onenote.exe. This association is created with the addition of a new URL protocol.The simplicity makes the launching the protocols to be easier in windows web browsers. The browsers include; Safari, Chrome, Opera, IE, and Firefox support the application protocols. This is done by the use of Windows ShellExecuteEx. However, the browsers behave differently in launching the protocols. This simplicity makes the application protocols acutely vulnerable.

Thus, the browsers prompt a user every time in launching the wanted program.The user has the leeway of prompting a task. This is done by asking any time anew task is to be performed. The default value used for enabling the warning is 0xi, while the one used for disabling the warning is 0x0. The application developer or administrators do set the policy on behalf of the user. However, due to security reason the prompt is discouraged. In the later versions of window launching of the Application Protocol URL for handling will require consultation of Protected Mode Evaluation policy.

This will help in target execution (Javier, 2002). The policy by default will ensure the user is prompted for access, to launch the program at Medium Integrity Level.The vulnerabilities of application protocols came from the developers. The developers do build support for the feature in their programs. In most case, this becomes a source of security bugs. This is because the programs are not written with untrusted data expectation. This web supplied URL is passed on the command line. The vulnerable programs have simple logic bugs.

This can be in from of buffer overflowing due to failure to handle command line arguments that are longer than the fixed size. Others can have complex problems. For example, some programs without confirming with the user, undertake a lasting design change. Decoding and encoding the URLs before passing through a target program is another behavior employed by developers.Developers of the Web can not provide for a way of detecting whether a client has given a protocol that is unavailable. Showing the unregistered protocols is done differently by the application protocols.

At the same time, there is no standard way of detecting a user’s browser in invoking a protocol (Troppens, 2011). The availability of application protocols is detected by commands.
