Be Paranoid About Your Website Traffic
Website hacks happen on one of two ways, from external sources or internal sources.
You’ve established strong passwords, validated user input, kept your software updated and limited viewable personal and business data. You’re paranoid and off to a great start. But now you need to monitor your website traffic.

Website logs are your friends. Use them. If you don’t have access to these logs contact your hosting company and find out what they have available for your use. If your site gets little traffic, examining the logs manually will be easy. Read more…

Company EXAMPLE may use a wildcard to blacklist *@EXAMPLE.com and then whitelist their legitimate email accounts, such as john_doe@EXAMPLE.com. The spam filters will give special consideration to email accounts appearing on the whitelist. Here is where a major problem may begin. Read more…
