I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

@Gregory Ambrose - You have several options depending on the environment you are working in. For example,
Is the site hosted on a Windows or LINUX based server?
Is the site on a local intranet or public facing Internet?
Is the server managed in-house or by hosting provider?

Yes, you can leverage CF to block specific IPs or range of IPs. However, you have to maintain the list if the IP changes.

The site faces the public on a windows server provided by a hosting company.

@Gregory Ambrose - If you suspect malicious user(s) via Internet traffic, then your best defense might be to have your hosting provider block the suspect IP range. Sometimes the control panel tools for management of your site allow you to perform this task yourself.

In addition to @gdemaria solution, you could add an application enhancement that captures the client IP in a table after certain conditions are met. Then use some sort of UDF, OnRequest, code to automatically restrict site access if the IP address was logged...
