Schema

Table: audit_selinux

Represents SELinux information.

Name Datatype Description
type UTF8 A string representing the SELinux event type name, such as MAC_POLICY_LOAD.
time UINT_64 The UNIX nanoseconds timestamp of the SELinux event.
message UTF8 The SELinux event's msg field.

Table: audit_user_msg

When a user starts a terminal, netlink events trigger an audit_user_msg event. You can use audit_user_msg events to track SSH login attempts, sudo elevations, and users swapping to different system users. You can also track events inside containers.

Name Datatype Description/Attributes
uid int32 The UID of the process triggering the event.
pid int32 The PID of the process triggering the event.
sophos_pid string A unique ID created using the PID of the process and a unique identifier.
type int32 The nlmsg_type value of the netlink event.
time int32 The Unix timestamp of the event.
message string

The first key=value pair from the netlink event message field.

For example, the message from the following audit_user_msg event is op=login:

op=login

id=1000

exe=\"/usr/sbin/sshd\"

hostname=172.28.112.1

addr=172.28.112.1

terminal=/dev/pts/3

res=success
path string The path of the process triggering the event.
address string The IPv4 or IPv6 address if the event is triggered over the network. You typically see this in SSH or container events.
terminal string The terminal ID of the created terminal.
