As part of their Make Waves series, iThemes will be conducting a free webinar with Dre Armeda of Sucuri.net to discuss how to lock down a WordPress installation. In this webinar, viewers will learn how to reduce their risk of being attacked by hackers and malware threats. The webinar takes placed on Wednesday, April 25th at 1 P.M. CDT. I’ve linked to Sucuri a number of times during the year because these guys know what they’re talking about when it comes to website security.
