  description: "A Threat Intelligence API service\n\n  This API provides a mechanism for making Judgements on the Disposition\n  of Observables, which are then distilled into a final Verdict.  A\n  Disposition is a statement regarding the malicious, or otherwise,\n  nature of an Observable.\n\n  The Judgements can be grouped into Indicators, which can be associated\n  with Campaigns, Actors and TTPs.  Feedback can be given on specific\n  Judgements, indicating agreement or disagreement, or clarification.\n\n  When an Observable with a malicious Verdict is seen, it can be recorded as\n  a Sighting, and the Relations that Observable had with other Observables can\n  be recorded as well.\n\n  We support a pre-defined set of Observable Types.  Each Observable Type has a\n  specific form of natural identifier, its ID, which is almost always\n  the default way it is represented when observed in the wild.\n\n  * Ipv4/IPv6  -- 192.168.1.1\n  * Domain/Hostname -- foo.com, www.bar.com\n  * SHA256  -- the sha256 checksum of a file, or other data blob\n  * MD5 -- the md5 checksum of a file, or other data blob\n  * SHA1 -- the sha1 checksum of a file, or other data blob\n  * URL -- A minimal form of the URL\n\n  The Verdict is derived from all of the Judgements on that Observable which\n  have not yet expired.  The highest priority Judgement becomes the\n  active verdict.  If there is more than one Judgement with that\n  priority, than Clean disposition has priority over all others, then\n  Malicious disposition, and so on down to Unknown.\n\n  <a href='/doc/README.md'>CTIA Documentation</a>"

It can be used to provide additional context and information about the entity. The primary purpose of this field is to help analysts filter and prioritize entities based on their knowledge and expertise of different languages.


            For example, if an incident involves an attack on a system in a country where a specific language is predominant, the `language` field can be used to indicate that language, which can help analysts to quickly identify and respond to incidents that may be geographically or culturally relevant. This information can be used to prioritize incidents based on their potential impact. The `language` field can also be used to help with correlation of incidents across different systems and regions, as well as to help with data analysis and reporting.'

            It is used to indicate the sensitivity of the information contained within the message. This allows recipients to determine the appropriate handling and dissemination of the information based on their clearance level and need-to-know.


            For example, an entity containing information about a critical vulnerability in a widely-used software might be marked as `red`, indicating that it should only be shared with a small group of highly trusted individuals who need to know in order to take appropriate action. On the other hand, a message containing more general information about security threats might be marked as `amber` or `green`, indicating that it can be shared more broadly within an organization.'
