Here are our top tips and advice for protecting against Linux Ransomware: 

Backup critical files and diversify the storage media to avoid a single point of failure (SPOF). This won’t prevent an attack, but can mitigate potential damage.

Keep servers and endpoints up to date to ensure that they use the latest security patches.

Implement the principle of least privilege for user accounts.

Monitor network activity and system logs closely.

Keep tabs on event logs to identify anomalous behavior before it causes harm.

Use a combination of IP filtering, an intrusion detection system (IDS) and an intrusion prevention system (IPS).

Use Linux security extensions that control and restrict access to data or network resources.

Implement robust network segmentation and data compartmentalization to minimize the impact of a potential ransomware attack.

Audit systems regularly.
