A security administrator needs to provide access from partners to an Isolated laboratory network inside...

A jump box is a system that is connected to two networks and acts as a gateway or intermediary between them1. A jump box can help to isolate and secure a network by limiting the direct access to it from other networks. A jump box can also help to monitor and audit the traffic and activity on the network. A VDI (Virtual Desktop Infrastructure) is a technology that allows users to access virtual desktops that are hosted on a server2. A VDI can help to provide users with the necessary tools and applications for analysis without installing them on their own PCs. A VDI can also help to reduce the maintenance and management costs of the desktops. A VDI can operate in two modes: persistent and non-persistent. In persistent mode, each user has a dedicated virtual desktop that retains its settings and data across sessions. In non-persistent mode, each user has a temporary virtual desktop that is deleted or reset after each session3. In this scenario, deploying a jump box to allow access to the laboratory network and using VDI in non-persistent mode can meet the security objectives of the request. The jump box can prevent the partners’ PCs from connecting directly to the laboratory network and reduce the risk of unauthorized access or compromise. The VDI in non-persistent mode can provide the necessary tools for analysis without storing any data on the partners’ PCs or the virtual desktops. The VDI in non-persistent mode can also allow the partners to run long analyses without losing their progress or results. Deploying a firewall (B) may not be sufficient or effective, as a firewall only filters or blocks traffic based on rules and does not provide access or tools for analysis. Using VDI in persistent mode (A) © may not be secure or efficient, as persistent mode stores data on the virtual desktops that may be sensitive or confidential.
