French SMEs Face Common IT Maintenance Mistakes

Many small and medium‑sized enterprises in France overlook basic IT maintenance tasks, creating serious security and reliability risks. Common errors include failing to apply critical kernel and software updates, leaving services such as databases, admin tools or caches (e.g., Redis) exposed to the Internet, and running outdated web servers like NGINX or Apache that are vulnerable to known CVEs.

Neglecting regular backup testing and resource management further amplifies the danger, as data loss or system slowdown can occur when disks fill with obsolete files. The articles advise proactive update policies, routine audits of open ports, automated and off‑site backup verification, and systematic cleanup of unnecessary data to protect against breaches and downtime.
