    • Treat problems with connections to the cloud as errors — Logs problems connecting to the Skyhigh Security GTI server as errors.
    • Treat invalid URLs as errors — Logs invalid URLs as errors.
    • Do a backward DNS lookup also for private addresses — Uses the DNS lookup tool to find the domain names corresponding to private IP addresses and uses the domain names for the filtering process.

  6. When these GTI Settings are selected, the feature:
    • Search URL path for embedded URLs and categorize them — Searches the URL for embedded URLs and rates the embedded URLs. These ratings affect the rating of the URL overall.
      NOTE: Selecting this option can lower performance.
    • Parse web page content for URLs and block them — Blocks webpages containing URLs.
    • Do a forward DNS lookup to categorize URLs — Uses the DNS lookup tool to find the IP addresses corresponding to unrated URLs and uses the IP addresses in the filtering process.
    • Do a backward DNS lookup for unrated IP-based URLs — Uses the DNS lookup tool to find the domain names corresponding to unrated IP address-based URLs and uses the domain names in the filtering process.
    • Detect URLs based on built-in keywords — Includes built-in keywords in the search for URLs.
    • Enable the Dynamic Content Classifier if GTI web categorization yields no result — Uses the Dynamic Content Classifier categories for URLs that Skyhigh Security GTI is unable to rate.
  7. (Dynamic Content Classification) Click Add Category to add categories to the DCC process, then select an option:
    • Select Supported Categories to select all categories, then click Done.
    • Expand Supported Categories to select categories individually, then click Done when finished.
