IIS Web Login Protection
Protection Overview Many of the Web Servers use built-in IIS Authentication methods to limit access to some parts of the website like admin panels and customer areas. The most commonly used authentication methods are Basic, Digest and NTLM. Being widely used, these authentication methods are subject to brute-force attacks on a regular basis. Everyone is able to download freely available brute-force tools and start abusing your server and flooding the logs with thousands of failed login attempts like below:
