1. Overview

This article provides an overview of improvements and resolved issues in the Fortanix Filesystem Encryption (FSE) for Linux 1.5.65 release.

2. Improvements

• Fortanix FSE agent now restricts users with sudo privileges from modifying, deleting, or creating encrypted files on Linux systems running Ubuntu 22.04, Ubuntu 24.04, RHEL 9, RHEL 10, SUSE 15, and Amazon Linux 2 to safeguard encrypted data and maintain Fortanix FSE agent stability (JIRA: FSE-446).

3. Bug Fixes

• Resolved an issue where users without sufficient policy permissions were able to modify or overwrite encrypted file contents using text editors such as vi or gedit on Linux systems (JIRA: FSE-474).

NOTE

• You must have Fortanix Data Security Manager (DSM) version >=4.29 and FSE Agent version >=1.0.29 to access the FILE DECRYPTION POLICY tab in DSM user interface (UI).

• For existing FSE-Linux users (with FSE Agent <1.0.29) -
