Problem No Problem - Platform Security

The system is designed with comprehensive security throughout.

The platform’s architecture is central to providing maximum security. The agent which is installed on the client PC initiates all communications back to the server. Since the agent will not accept any inbound connections, it is virtually impossible for a third party application to attack the agent from the network. The system does not need any input ports opened on client machines. This lets the agent do its job in virtually any network configuration without introducing any susceptibility to inbound port probes or new network attacks.

Problem NoProblem's server protects against man-in-the-middle attacks by encrypting all communications between the agent and server with 256-bit RC4 using a key that rolls every time the server tasks the agent (typically at least once per day). Since there are no plain-text data packets passing over the network, there is nothing available for an attacker to exploit.

The Problem NoProblem portal is accessed through a web interface after a secure logon process. The system never sends passwords over the network and never stores them in the database. Only each administrator or user knows his or her password. The client side combines the password with a random challenge, issued by the Problem No Problem server for each session, and hashes it with SHA-1. The server side tests this result to grant access or not. The unique random challenge protects against a man-in-the-middle attack sniffing the network, capturing the random bits, and using them later to access the VSA.
