CSP directives supported by policies
Page Shield policies support most Content Security Policy (CSP) directives, covering both monitored and unmonitored resources. You can use a policy to control other types of resources besides scripts and their connections, even though Page Shield is not monitoring these resources.
Each CSP directive can contain multiple values, including:
- Schemes
- Hostnames
- URIs
- Special keywords between single quotes (for example,
'none') - Hashes between single quotes (for example,
'sha384-oqVuAfXRKap7fdgcCY5uykM6+R9GqQ8K/uxy9rx7HNQlGYl1kPzQho1wx4JwY8wC')
Hostname and URI values support a * wildcard for the leftmost subdomain.
The following table lists the supported CSP directives and special values you can use in Page Shield policies:
