A Bastion, also known as a checkpoint or jump server, is an essential component of IT security.

A Bastion is a specially secured server located between an internal network and an unsecured network, such as the Internet. It serves as a control point for managing access to internal resources, limiting direct connections from untrusted networks and using advanced security protocols and robust authentication methods.

It ensures that access is limited to authorized users and secured against external threats.

A Bastion allows :

• Isolate internal resources from public Internet traffic, reducing the attack surface and protecting against online threats.
• Record and monitor all access sessions, providing complete traceability and facilitating auditing and activity analysis.
• Enhance security by strictly controlling and monitoring access to sensitive resources.
• Facilitate access management by centralizing and controlling entry points to company resources.

Bastion plays a crucial role in an organization's overall security strategy, ensuring the integrity, confidentiality and availability of systems and data.
