  • 7.  WordPress   Drupal   Joomla  
  • 8.  What is it? You tell me…  Who is right?  My thought: Any steps that may eliminate a large subset ofattacks on your blog should be taken.
  • 9.  The basics  Passwords  Communication (Plain Text vs. SSL)  Updates  Watch what you add to your sites (plugins/themes/add-ons)  Backups  Google Webmaster Tools
  • 10.  Use strong passwords Make them unique in high value situations
  • 11.  Pay attention to how you are sending your passwords  Wireless Networks = Risk  FTP – Use SFTP instead  Email – Use SSL Ports 587,995,993 vs 25,110,143  Skype – Syncs history upon connect, never send secure passwords – EVER  CPanel/WHM/Admin pages – if it is http not https, your password can be scraped
  • 12.  Keep your blog, plugins, themes, & operating system current – yes, even Linux Security and attacks improve over time 2005 – Admin operations required a referrer 2006 – Admin operations required a NONCE 2007 – Plugin pages forced to check security 2008 – Randomized keys and salts & upgrades 2009 – Security escalations issues – full review 2010 – Automated plugin and theme upgrades 2011 – Sniffing, upload, clickjacking, file cleanup
  • 13.  Every plugin or theme is a security risk “Free Theme” sites are a very high risk Less popular & highly specialized plugins have had less eyes on them and are riskier Older plugins used older security standards - we simply knew less and had fewer tools You are responsible for your site. Learn how to identify problems or make a friend who can.
  • 14.  Both files and database Keep the files offline If you have files online keep them out of public_html As important as having the backups… Know how to restore them! Before you restore – delete the files and directories to remove the hack files
  • 15.  How do you know you are hacked? Google will email you when they consider you a risk    You can configure multiple owners
  • 16.  EVERYTHING that is displayed on the screen must be filtered.  WordPress provides: esc_html esc_url esc_* EVERYTHING that you send to the database must be filtered.  WordPress provides: $wpdb->prepare TRUST NOTHING  Try to use your text instead of user input
  • 17.  Permissions - The 755 myth  chmod -R 755 *  Generic: Directories Should be 755 Files 644  Reality: The least privileges provides the most access VPS vs Shared Hosting vs Managed Hosting  Flexibility, Access, Less risk = More $  Harden your own server or let someone do it  suPHP – Isolates your installation
  • 18.  Create a “Editor” user for posting Create a new “Administrator”, delete the old one, then only use it for maintenance Never use wp_ as your table prefix Look at wp-config-sample.php now and then and update your wp-config.php Force Secure password logins 
  • 19.  Move wp-config.php Remove version Info Rename the admin user Move your wp-content directory – Possibly worth doing but will break many plugins and themes Use .htaccess to white list IP addresses or add an extra password layer
  • 20.  Free Plugins  exploit-scanner  wp-security-scan  wordpress-file-monitor Paid Plugins
  • 21. Site Rescue, Securing & Code Review     Managed Hosting    WPSecuritylock.comAnd of course doing it all: 
