HTTPS is a protocol that implements a strong encryption layer around the HTTP protocol. Data sent across the Internet using HTTPS is secure and cannot be decrypted and read by any eavesdropper. This makes HTTPS a useful protocol for secure online transactions.
Searching for images with search engines like Google, Yahoo, and MSN may allow users to view adult images. These cannot be blocked in a simple way, since it would be undesirable to block all images from a search engine. Several search engines offer a safe-search* feature, which blocks most adult images. Setting the safe-search parameter in ufdbGuard enforces the safe-search policies of these search engines. The default value for the parameter is ON. The safe-search feature enforces safe searches for the following search engines: A9, Alltheweb, Ask, BuscaMundo, Dogpile, Excite, Foxnews, Google, Hotbot, Infospace, Live, Lycos, Metacrawler, Metaspy, MSN, Webcrawler, Webfetch, ya.com, Yahoo.
Usually, websites that use HTTPS for legitimate reasons use a signed SSL certificate and a fully qualified domain name for maximum security and a clear identification of the website. In contrast, untrustworthy websites that use HTTPS will use self-signed SSL certificates and an IP address instead of a domain name. Therefore, ufdbGuard can be configured to control access to HTTPS websites using 2 settings:
By default, these settings are set to “ON” in the ufdbGuard.conf file. We recommend to keep these settings. In case that a legitimate website uses an IP address in the URL, or an SSL certificate that is not signed by a trusted authority, just add this site to the locally trusted websites.
To keep the database with URLs to be blocked up to date, ufdbGuard has a feature to recognize URLs that are not yet part of the URL database. These URLs are uploaded to be included the next day's URL database.
