Review the definitions for terms used across Cloudflare's Bots documentation.

| Term                       | Definition                                                                                                                                                                   |
| -------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| bot                        | A software application programmed to do tasks that can be used for good (chatbots, search engine crawlers) or for evil (inventory hoarding, credential stuffing).            |
| bot score                  | A score from 1 to 99 that indicates how likely that request came from a bot, in which 1 to 29 is likely automated and 30 to 99 is likely human.                              |
| bot tags                   | Additional information about a bot request, such as why Cloudflare has given it a bot score and whether the request came from a verified bot or a category of verified bots. |
| Challenge solve rate (CSR) | The percentage of issued challenges that were solved.                                                                                                                        |
| detection ID               | Static rules that are used to detect predictable bot behavior with no overlap with human traffic.                                                                            |
| JA3 fingerprint            | JA3 and JA4 fingerprints profile specific SSL/TLS clients across different destination IPs, Ports, and X509 certificates.                                                    |
| verified bot               | Bots that are transparent about who they are and what they do.                                                                                                               |
