The web filtering blacklist in Panda GateDefender Performa contains domains, sites or specific addresses which, even though they don’t belong to a restricted category, must not be accessible to network users.
Similarly, the web filtering white list contains domains, sites or specific addresses that belong to a restricted category but that will always be accessible to network users.
The web filtering white lists and blacklists are configured based on:
- Full URL (www.domain.com/address): Only this address will be excluded from the filter (page, file or directory).
- Website (www.domain.com): All of the addresses belonging to the site will be excluded from the filter: (www. domain.com, www. domain.com/address _1, www. domain.com/address _2, etc.).
- Domain or subdomain (domain.com or subdomain.domain.com): All of the addresses belonging to all the websites in the domain or subdomain will be excluded from the filter (www.domain.com, www3.domain.com, XXX.domain.com/address).
What will happen if the blacklists or white lists are configured by IP address?
For the white lists and blacklists to work correctly, the URL of the web page must be added, since the configuration by IP address can be more restrictive, causing undesired effects on web filtering performance.
The www.domain.com site of online purchases has its main page stored on the server with the IP address 220.127.116.11. The images and content of the items sold, however, are stored on the server with IP address 18.104.22.168.
In the web filtering, the restriction to the Online orders category is configured. Nevertheless, the administrator wants the www.domain.com site to be accessible and therefore adds the site to the white list.
If the IP address 22.214.171.124 is included, Panda GateDefender Performa will allow access to the main page. However, it will not allow viewing of images or items, since they are stored on the server with IP address 126.96.36.199 (www.domain.com/products). Since the server has been classed by the web filtering under the Online orders category, GateDefender Performa will not allow access to the sections.
However, if the URL address is added in the blacklist and white list settings, Panda GateDefender Performa will allow access not only to the main page, but also to secondary pages containing the images and products.
