File Transfer Protocol

Client

Angler Product Internal

Challenges

The client wanted to develop a secured FTP tool for File transfer operations from local to the remote server or vice versa. The product's FTP operations would be similar to FTP clients like Filezilla, CuteFTP. All the FTP operations like upload, download, delete, rename, chdir, mkdir, chmod would be done in a highly secured mode and every user operations would be tracked in the logs which are maintained in the database. The application has to keep track of the FTP profiles and the operations done by the user or group. Further privilege based File Transfer Protocol operations should be possible. Policies can be allotted for users or groups or for FTP profiles which when violated can be either intimated to administrator through mail or locks stored for the users or groups against FTP profiles.

In such a case, the user will be allowed to log into the application only when the administrator releases the lock on him. Reports can be generated based on the profiles, FTP operations like upload, download, delete, chmod and mkdir for users.

What We Did

Results

The product compared to other FTP clients offers the below benefits

• All other FTP clients store the users' operations in the logs. Here transactions in the remote are stored in the database
• Restrict the users or groups to perform FTP operations in allotted server profiles & allotted directory which is highly recommended as they cannot navigate to other directories
• Privilege based operations restrict them to only specific operations in the remote server
• Policies enable the administrator to watch the user activities against the framed rules. This restrict them from performing certain activities say uploading or downloading movie files
• Tracking the activities in the database enables the administrator to generate reports
• Bulk files can be uploaded or downloaded within minutes
