Limitations for Device Posture support

  1. Auto updates of Operating System (OS)

If you're using Device posture on Ubuntu, automatic detection of OS upgrades is possible only if configured with apt unattended-upgrades package See AutomaticSecurityUpdates in Ubuntu documentation.

  1. Device Certificates

Device certificates are detected for certificate profiles only if they are configured in these two forms:

  • Using the NSS-Shared DB in Linux Cert Management.
    a.The private key must be added as an identity and must show up when you run certutil -d sql:$HOME/.pki/nssdb -K
    b. A certificate must exist with the same alias as the private key from the above command.

  • Certificates are stored as flat files in a directory.
    a. Only $HOME/.certs directory is supported.
    b. Only container formats with these extensions are supported, .p12, .pfx
    c. If the organization manages certs and keys separately, EAA supports the following formats - .key for private keys and .crt for certificates
    d. For private keys, EAA only supports PKCS1 and PKCS8 private keys encoded in PEM format. EAA supports rsa, ecdsa, and ed25519 private keys
    e. For certificates, EAA supports any PEM encoded valid x509 certificate.

  1. ETP integration is not supported.

  2. Anti-malware support
