+# Security concerns
+
+Castopod is built on top of [CodeIgniter4](https://codeigniter.com/), a PHP
+framework that encourages
+[good security practices](https://codeigniter.com/user_guide/concepts/security.html).
+
+To maximize your instance's safety and prevent any malicious attack, we
+recommend you update all your Castopod files permissions after installation or
+updates (to avoid any prior permission error):
+
+- `writable/` folder must be **readable** and **writable**.
+- `public/media/` folder must be **readable** and **writable**.
+- any other file must be set to **readonly**.
+
+For instance, if you are using Apache or NGINX with Ubuntu you may do the
+following:
+
+```bash
+sudo chown -R root:root /path/to/castopod
+sudo chown -R www-data:www-data /path/to/castopod/writable
+sudo chown -R www-data:www-data /path/to/castopod/public/media
+```
