Site Firewalls: 6G

The 6G WAF was originally developed by Jeff Starr at Perishable Press for Apache-based servers.

6G is an excellent lightweight firewall that parses requests for anything anomalous or malicious looking, looking for:

• Bad Bots
• Bad Referrers
• Bad Query Strings
• Bad Requests
• Disallowed Request Methods

We have adapted the firewall for Nginx, but more details can be found here.

Logging, working with rulesets and whitelisting information can be found here.

Turn on 6G WAF

Enable the 6G firewall where {site.url} is your WordPress site’s primary domain.

gp site {site.url} -6g-on

Turn off 6G WAF

Disable the 6G firewall where {site.url} is your WordPress site’s primary domain.

gp site {site.url} -6g-off
