Michele Butcher gave a presentation on beginner WordPress security. She emphasized that security is important because hackers are constantly finding new ways to access information. Hackers hack sites for a variety of reasons like money, spreading malware, or boredom. The most common ways sites are hacked are by guessing login credentials, denial of service attacks, exploits in themes/plugins, FTP/cPanel configurations. She provided many tips for improving security like using strong passwords, two-factor authentication, updating often, only using necessary plugins/themes, and backing up sites.
