Profil output aws-ct-timeline

Suzaku akan menampilkan informasi berdasarkan file config/default_profile.yaml: 

Timestamp: '.eventTime'
RuleTitle: 'sigma.title'
RuleAuthor: 'sigma.author'
Level: 'sigma.level'
EventName: '.eventName'
EventSource: '.eventSource'
AWS-Region: '.awsRegion'
SrcIP: '.sourceIPAddress'
UserAgent: '.userAgent'
UserName: '.userIdentity.userName'
UserType: '.userIdentity.type'
UserAccountID: '.userIdentity.accountId'
UserARN: '.userIdentity.arn'
UserPrincipalID: '.userIdentity.principalId'
UserAccessKeyID: '.userIdentity.accessKeyId'
EventID: '.eventID'
RuleID: 'sigma.id'

  • Setiap nilai field yang diawali dengan . (ex: .eventTime) akan diambil dari log CloudTrail.
  • Setiap nilai field yang diawali dengan sigma. (ex: sigma.title) akan diambil dari aturan Sigma.
  • Saat ini kami hanya mendukung string namun berencana untuk mendukung tipe nilai field lainnya.

Catatan: Jika Anda ingin menampilkan data JSON asli dan memastikan Anda tidak kehilangan informasi field apa pun, cukup tambahkan opsi -R, --raw-output ke perintah aws-ct-timeline.
