MISP 2.4.127 released
A new version of MISP (2.4.127) has been released with an improved version of attributes decaying, new set of widgets, many improvements and bugs fixed.
Improved decaying of attributes (version 2)
In MISP 2.4.116, a decaying functionality was added to allow users and organisations to easily expire information depending on their personalised objectives and targets.
Based on the feedback of the organisations relying on the decaying feature, the following improvements were included:
-
Added a new user setting,
default_restsearch_parameters, allowing users to supply restSearch parameters that will be automatically passed to the export mechanism during API queries fetch. The main purpose of this new setting is to enable users to inject filters when integrating with third-party tools not offering the possibility to control the queries performed against MISP. This for example allow to set the default decaying parameters to all restSearch queries performed by the given user. -
Added a new setting,
tag_numerical_value_override, allowing users to override thenumerical_valueof tags. The main purpose of this new setting is to let users convey their own numerical values for tags. It does not constrain site-admins to the values provided by the official misp-taxonomy repositor, and instead allows them to define new values for entries not having a numerical value in the first place.
Major changes in decay computation
Attributes' last_seen will now takes precedences over their timestamp if the former is set. In the decaying implementation prior to this version, if no sightings were recorded, the simulated last sighting was set on the timestamp value. However, in this new version, the last_seen value will be used instead. Users will be able to alter attributes (attach tags, modify last_seen, ...) without refreshing the decaying score to its maximum value.
New widgets added to MISP
Additional widgets (contributed by Koen Van Impe) were added in MISP with the following features:
- Widget to display system resources (df, cpu, mem)
- Widget to display the latest sightings
- Widget to display the false positive sightings above certain threshold
Don't hesitate to contribute your own widgets and take a look at the existing ones.
Various improvements
- [cli] Command for pulling from all remote servers.
- [UI] Add event ID to page table.
- [events:distributionGraph] Added close button in popover.
- [correlations] Refactored correlation saving.
- Always show other correlating value (useful for CIDR correlations)
- Make correlation saving faster (move more work to database, do not fetch not necessary fields)
- Fix some small bugs
Many other improvements are documented in the complete changelog is available.
