Hackers have been trying to break into websites 24/7 and spammers have been equally busy at their craft.
WP websites are generally hosted in a fairly lavish environment with high amounts of bandwidth. They offer a desirable place for hackers to take up residence and set up a command center from which to launch attacks on visitors and other websites on that server.
LOCK THE ENTRYWAY
Typically hackers work like an amateur burglar who walks down a hallway testing doorknobs until they find one that opens. To avoid this type of break-in be sure that you are not using the default â€˜adminâ€™ as the username and come up with a strong password.
UPDATE PLUG-INS & THEMES
Just as it is important to keep your antivirus software up-to-date on your computer, it is important for business owners to protect their CMS platform by regularly updating plug-ins, themes & Word Press when updates are available.
As annoying as they are, installing CAPTCHA fields will make it more difficult for spam robots to send and create a traffic jam on the mail server.
In an ideal world, comments would be a welcome addition to a blog. But in the real word comments add little value to the conversation and disabling them will cut back on the time that the blog administrator spends weeding out the spam.
