For the WP Security settings, I decided to add basic and 6G firewall protection. This should keep the site fairly protected. I also added spam detection so that bots can not spam my comments. I also made sure that spam comments would be deleted in a week. I am also blocking character strings that resemble XSS attacks.
For the WP Super Cache setting, I turned caching on. I also increased the time until cache timeout until 3600 seconds. I also enabled CDN support.
