[good security practices](https://codeigniter.com/user_guide/concepts/security.html).

To maximize your instance safety and prevent any malicious attack, we recommend

you update all your Castopod files permissions:

you update all your Castopod files permissions (after installation to avoid any

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**.

// TODO: add instructions on how to set file permissions.

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

```
