Anura Definitions - Rule Sets
To make accurate judgements on visitor quality, Anura has built a continually growing list of rules and heuristics. To provide transparency as to why traffic is scored as BAD or WARNING, we have categorized each of these rules/heuristics into one of seven different Rules Sets. Each of these Rule Sets have multiple rules/heuristics to ensure the accuracy of the Rule Set.
Anura analyzes data that we have collected about the visitor to provide responses regarding their quality. During the process, data is collected and data integrity is insured. The purpose is to provide accurate and consistent data over the life-cycle of the session. This information must remain fully in-tact without any alteration of data. If Anura detects any data inconsistencies, it will trigger one or more of the rules within this rule set.
Anura identifies and analyzes the visitor's digital environment, which includes the hardware and software they used to connect to your web asset. With that information, Anura checks for abnormalities within the environment that are consistent with bots, malware, or human fraud.
A data center is a facility that houses remote storage of data, web servers, and servers, all which aid in powering the Internet. While data centers are paramount to most networks' critical systems, and are vital to daily operations, they do not typically generate real visitors. When data is received, Anura determines if the visitor originated from established data centers.
The flow of visitors across the Internet generates data which tells us where the visitor has been prior to visiting your web asset. With the information gathered, Anura reviews prior origin data to determine if it has come from a known fraudulent site, or if it gives indications of questionable origination.
An IP address is like a physical address - multiple people may use the same address. IP addresses can be compromised and used to generate fraudulent visitors. Anura validates each visitor's IP address for integrity using a combination of proprietary factors, as well as, referencing historical data of known nefarious origins.
Internet spoofing is the practice where the nefarious visitor changes aspects of their identity or system settings to represent themselves as a legitimate visitor to your content. Anura has a series of rules/heuristics designed to validate the visitor and assure that no manipulation of origin or identity has occurred.
Web crawlers are Internet bots that scour the web with the purpose of indexing the contents of websites. Legitimate websites, such as search engines, use web crawlers to provide the most up-to-date information available on the web. Using both public and private lists, Anura checks to make sure the visitor is not a known web crawler such as Googlebot.
