Choosing Safer File Permissions for an Evolution CMS Project
Loose permissions may make a site easier to deploy quickly, but they also make a compromised or misconfigured server easier to abuse.
File permissions are one of those topics where teams often inherit unsafe defaults without revisiting them. The old question behind this post listed typical permissions for cache, images, exports, and config files and asked whether they were really appropriate.
The Core Principle
Permissions should be only as open as the application actually needs. A working site is not proof that the permissions are correct—only that they are permissive enough.
Why This Matters
- overly open cache and image directories increase the blast radius of compromises
- configuration files deserve the strictest protection possible
- hosting defaults are not always aligned with application security
Practical Recommendation
Review writable directories separately from read-only application files. Keep config files tight, keep only the necessary directories writable, and avoid using 777 as a casual default unless the hosting environment truly forces it and you have no safer path.
This old thread is still relevant because security hygiene often starts with boring but important filesystem discipline.
