SMB/CIFS AppSim Update
With the release of StrikePack 21889, the SMB/CIFS AppSim module has been improved from our first version which was released last week. Among the improvements are a number of customization options which are now exposed to the UI. First, the user can now provide their own custom data file to be used as payload data during file transfers, as well as indicate a file chunk size to be used for each request of a portion of the file being transferred. The user can also now configure session parameters for use such as client and server name, domain name, username, and password. If any of the available customization options are not modified by the user, they are randomized to provide each traffic flow with a unique set of session parameters.
Stay tuned for more upcoming improvements and expansions to the SMB/CIFS AppSim as well as the addition of new protocol modules as we continue to improve our Application Simulator component.
SMB/CIFS Application Simulator
In our recent StrikePack 21396, SMB/CIFS application traffic simulation has been improved from standard SMB traffic to a more dynamic AppSim module. With the initial release of the new module two SMB flow scenarios have been included; an SMB NULL Session and an SMB/CIFS Client File Download. The former simulates an SMB NULL client connection to the server's IPC$ share. The latter however simulates an authenticated client connection to a shared resource on the server, performs a directory listing, then retrieves information about and downloads a file found there. With the first release of this AppSim module as delivered by the StrikePack mentioned above, these two traffic flows use fairly static data such as the filenames found in the directory listing of the shared resource and the data contained within the target file, although some customizations are exposed to the UI such as client hostname, server hostname, username, etc. In a forthcoming update however, many of the parameters for the Client File Download scenario will be randomized by default, and many more parameters will be exposed to the UI for customization by the user.
