-Sighting is an [endless topic of discussion](https://lists.oasis-open.org/archives/cti-stix/201508/msg00019.html). This is a required feature especially when information or indicators are regularly shared to gather feedback from users of the shared information. Adequate sightings can be an incredible source of information in order to describe the life-time of an indicators, its evolution and especially to ensure the understanding among a group of users using the information to detect, mitigate or block in their infrastructures malicious activities. The potential is huge and can be a significant gain for organised communities of infosec professionals sharing information or even a requirement for any advanced algorithms ranging from machine learning or reinforcement learning. But to reach such state of feedback loop, you require a functional model of sighting.

-In early April 2016, MISP introduced the support of [sighting via the API](https://circl.lu/doc/misp/automation/index.html#sightings-api) or the UI. This first step was basically to support the existing description of sighting as described in the STIX standard and allow the support via STIX sighting documents or simplified sighting via MISP JSON attributes. This move in MISP allowed us to test sighting at large-scale in existing sharing communities like [the ones operated by CIRCL](https://www.circl.lu/services/misp-malware-information-sharing-platform/). The implementation allowed to have sightings at different levels (attributes or the sighting sum at the event level) with a support of sighting per organisation or per MISP instance level. We had engaging discussions about the current limitation of simple counters:

The implementation allowed us to have sightings at different levels (at the attribute level as well as a sighting sum at the event level) whilst also supporting the sightings per organisation or per the MISP instance level. We had engaging discussions about the current limitations of simple counters:
 
 - Positive and negative sightings cannot be interpreted as it's just a positive counter in the existing standards. Many users asked for a direct feedback regarding their false-positive interpretation of a sighting.
-- An absence of time-to-live reference time that could support advanced expiration model of an indicator.
+- An absence of time-to-live reference that could support advanced expiration models of an indicator.
-- Sharing of sightings alone is also required to support new model of pseudo-anonymous sharing.
+- Sharing of sightings is also required to support a new model of pseudo-anonymous sharing.
 
-To tackle this, we decided **to remodel and extend the sighting in this new release of MISP**. Now the sighting contains a type (which can be easily extended) to support alternative issue of simple counters. The following types were added:

+- Sighting type 0, the default sighting type using the default STIX interpretation of a sighting.
 - Sighting type 1, a **false-positive sighting** which means this sighting has been interpreted as a false-positive by the organisation.
-- Sighting type 2, an **expiration sighting** which defines when the sighted attributes is expired.
+- Sighting type 2, an **expiration sighting** which defines when the sighted attributes is to be expired.
 
-In addition to the flexible type format, we added a simple source field which combined with the organisation provides simple way to scope the sighting (e.g. honeypot networks versus backbone routers where the false-positive interpreation can be significantly different).

-In previous version of MISP, sighting used the basic counter model as described above. In addition to the classical model, MISP 2.4.66 now allows to do negative sighting to track the numbers of false-positives generated.  All the sightings are also track per organisation with an additional source. The source allows an organisation to track which equipments or infrastructure generated the sighting.

-This new feature allows many new use-cases like feeding MISP from ticketing system (like it's a false-positive), attributes must expire in 4 days or adding sighting from honeypots or network sensors.
