Description

After a review, we want to improve the following points related to the Overview section within wazuh-dashboard:

• Text sizes: We want to increase the font size of the KPI subtitles and the features descriptions.

  • Increase the font size of the kpi subtitles and the features descriptions #7033
  
  

• Malware feature: We want to change its current description by Check indicators of compromise triggered by malware infections or cyberattacks.

  • Update malware feature description #7036

• Agent summary feature: when there are no agents, we want to hide the graph and show a message and a button indicating the user how to deploy an agent. This was previously implemented as a yellow call-out between the top containers and the features containers.

  • Change agents summary no results #7041

• Mitre feature: we want to change its current description by Explore security alerts mapped to adversary tactics and techniques for better threat understanding.

  • Changed Mitre overview description  #7032

• VirusTotal feature and dashboards: We want to remove this section, as it is included in the new malware dashboard

  • Remove virustotal feature and dashboards in favor of malware dashboard #7038

• Feature containers have different margins between them and the top containers. We want a design on which the containers separations are homogeneous

  • Containers have different margins #7034
