MITRE ATT&CK Description: The adversary is trying to get into your network.

Initial Access consists of techniques that use various entry vectors to gain their initial foothold within a network. Techniques used to gain a foothold include targeted spearphishing and exploiting weaknesses on public-facing web servers. Footholds gained through initial access may allow for continued access, like valid accounts and use of external remote services, or may be limited-use due to changing passwords.

Possible playbook triggers:

  • The playbook can be used as a part of the “Courses of Action - Collection” playbook to remediate techniques based on kill chain phase.
  • The playbook can be used as a part of the “MITRE ATT&CK - Courses of Action” playbook, that can be triggered by different sources and accepts the technique MITRE ATT&CK ID as an input.
