Device Control for removable drives in KESL In today's Best Practices post, we’re looking at how to manage access to USB drives, external hard drives, and other removable drives on computers protected by Kaspersky Endpoint Security for Linux. In KESL, this is handled by Device Control. It provides flexible access control. For example, you can:  ✅ Allow access for specific users or user groups (KESL 12.3+), such as domain users  ✅ Specify the ID of a trusted device and grant access to a particular employee  ✅ Grant temporary access upon a user’s request (KESL 12.4)  ✅ Allow read-only access 👉When editing policies, make sure the lock icon is closed so that the changes are applied to managed devices👈 In version 12.4, you can also configure the message shown to users when a device is blocked. To monitor removable drives, create a Device Control events report in KSC and receive it by email.  💪 Strengthen your protection by scanning removable drives after they are connected. #kesl #kscl #tips
