There are many different security plugins available for WordPress. Below are the most recommended plugins and a brief explanation of the plugin from the developers.
WordPress Core Security
Notes from the plugin developer: “Wordfence Security is a free enterprise class security plugin that includes a firewall, anti-virus scanning, malicious URL scanning and live traffic including crawlers. Wordfence is the only WordPress security plugin that can verify and repair your core, theme and plugin files, even if you don’t have backups. Wordfence is now Multi-Site compatible.”
Notes from the plugin developer: “WordPress itself is a very secure platform.

Notes from the plugin developer: “Add your own virtual Blackhole trap for bad bots. The Blackhole plugin includes a hidden link to your pages. You then add a line to your robots.txt file that forbids bots from following the hidden link. Bots that ignore or disobey your robots rules will crawl the link and fall into the honeypot trap. Once trapped, bad bots are denied further access to your WordPress-powered website.”

Notes from the plugin developer: “Look-see Security Scanner is a relatively quick and painless way to locate the sorts of file irregularities that turn up when a site is hacked. This is broken down into multiple searches: Verify the integrity of all core WordPress files; Search wp-admin/ for unexpected files; Search wp-includes/ for unexpected files; Search wp-content/uploads/ for hidden PHP scripts;.”
Notes from the plugin developer: The Sucuri WordPress plugin “will monitor file changes, provide audit trails, apply hardening features and detect various types of malware, SPAM, and other infections. [It] allows Sucuri Firewall clients to access the Firewall dashboard without logging into their Sucuri account.
