There are many different wordpress plugins, some work locally, some work with a community; if you are looking for a plugin to secure your site against bruteforce (and likely other hack attempts) you can use the BruteProtect plugin.
BruteProtect is a cloud-powered Brute Force attack prevention plugin and the ONLY SECURITY PLUGIN able to guard against botnet attacks.
BruteProtect logs every failed attempt community-wide
When an IP has too many failed attempts in a specific period of time BruteProtect logs and blocks that IP across the entire BruteProtect network (your site included). The more users of BruteProtect the safer we all are from traditional brute force attacks, and distributed brute force attacks that use many different servers and IP addresses
