If curious you can also check the process capabilities set and decode their
capabilities set flags for -  permitted, inherited and ambient as below.
The capabilities set can differ based on process , user and privileges 

Example:

test$ ps alx | grep docker 
4     0    2068       1  20   0 1834532 76808 -     Ssl  ?          0:16
/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
0  1000   70187   65976  20   0  17868  2504 pipe_r S+   pts/7      0:00 grep
--color=auto docker
test$ 
test$ egrep Cap  /proc/2068/status 
CapInh: 0000000000000000
CapPrm: 000001ffffffffff
CapEff: 000001ffffffffff
CapBnd: 000001ffffffffff
CapAmb: 0000000000000000
test$ 

Decode the capability flags for this process

test$ capsh --decode=000001ffffffffff
0x000001ffffffffff=cap_chown,cap_dac_override,cap_dac_read_search,cap_fowner,cap_fsetid,cap_kill,cap_setgid,cap_setuid,cap_setpcap,cap_linux_immutable,cap_net_bind_service,cap_net_broadcast,cap_net_admin,cap_net_raw,cap_ipc_lock,cap_ipc_owner,cap_sys_module,cap_sys_rawio,cap_sys_chroot,cap_sys_ptrace,cap_sys_pacct,cap_sys_admin,cap_sys_boot,cap_sys_nice,cap_sys_resource,cap_sys_time,cap_sys_tty_config,cap_mknod,cap_lease,cap_audit_write,cap_audit_control,cap_setfcap,cap_mac_override,cap_mac_admin,cap_syslog,cap_wake_alarm,cap_block_suspend,cap_audit_read,cap_perfmon,cap_bpf,cap_checkpoint_restore
test$
