We'll cover the following
Overview
The use of jump servers allows an organization to limit access to production systems. A jump server can also serve as the only way to provide limited access from an internal network segment to a more exposed network segment or zone, such as a
- Blocking users from administrative access to production systems.
- Logging commands executed by a user.
- Limiting what commands a user can execute.
How it works
A user first logs on to a jump server. Once logged on, the user can then gain access (or jump) to one of the production systems the jump server has access to. Because all commands issued by the user are first sent to the jump server, this server can filter commands so that only certain ones are passed to the production system.
Every command that the user executes can also be logged for analysis and can generate alerts. An example of an action that may generate an alert is when a user attempts to add a new account to a production system, indicating a breach of policy or something more malicious.
