FYI:
Actually, I think the command below would be more to the point here (I
have no idea how they play together). For the case at hand, "proc_info"
may be what is done for processes, there doesn't seem to be an equivalent
to see open sockets.
solaris10% ppriv -lv
contract_event
Allows a process to request critical events without limitation.
Allows a process to request reliable delivery of all events on
any event queue.
contract_observer
Allows a process to observe contract events generated by
contracts created and owned by users other than the process's
effective user ID.

Allows a process to change a file's group ID to one other than
the process' effective group ID or one of the process'
supplemental group IDs.
file_chown_self
Allows a process to give away its files; a process with this
privilege will run as if {_POSIX_CHOWN_RESTRICTED} is not
in effect.
file_dac_execute

bits or ACL do not allow the process write permission.
In order to write files owned by uid 0 in the absence of an
effective uid of 0 ALL privileges are required.
file_link_any
Allows a process to create hardlinks to files owned by a uid
different from the process' effective uid.
file_owner
Allows a process which is not the owner of a file or directory
to perform the following operations that are normally permitted
only for the file owner: modify that file's access and
modification times; remove or rename a file or directory whose
parent directory has the ``save text image after execution''
(sticky) bit set; mount a ``namefs'' upon a file; modify
permission bits or ACL except for the set-uid and set-gid
bits.
file_setid
Allows a process to change the ownership of a file or write to
a file without the set-user-ID and set-group-ID bits being
cleared.
Allows a process to set the set-group-ID bit on a file or
directory whose group is not the process' effective group or
one of the process' supplemental groups.

ipc_dac_write
Allows a process to write a System V IPC
Message Queue, Semaphore Set, or Shared Memory Segment whose
permission bits do not allow the process write permission.

and the effective uid of the current process is not 0.
ipc_owner
Allows a process which is not the owner of a System
V IPC Message Queue, Semaphore Set, or Shared Memory Segment to
remove, change ownership of, or change permission bits of the
Message Queue, Semaphore Set, or Shared Memory Segment.
Additional restrictions apply if the owner of the object has uid 0
and the effective uid of the current process is not 0.
net_icmpaccess
Allows a process to send and receive ICMP packets.
net_privaddr
Allows a process to bind to a privileged port
number. The privilege port numbers are 1-1023 (the traditional
UNIX privileged ports) as well as those ports marked as
"udp/tcp_extra_priv_ports" with the exception of the ports
reserved for use by NFS.
net_rawaccess
Allows a process to have direct access to the network layer.
proc_audit
Allows a process to generate audit records.
Allows a process to get its own audit pre-selection information.
proc_chroot
Allows a process to change its root directory.
proc_clock_highres
Allows a process to use high resolution timers.
proc_exec
Allows a process to call execve().
proc_fork
Allows a process to call fork1()/forkall()/vfork()
proc_info
Allows a process to examine the status of processes other
than those it can send signals to. Processes which cannot
be examined cannot be seen in /proc and appear not to exist.
proc_lock_memory
Allows a process to lock pages in physical memory.
proc_owner
Allows a process to send signals to other processes, inspect
and modify process state to other processes regardless of
ownership. When modifying another process, additional
restrictions apply: the effective privilege set of the
attaching process must be a superset of the target process'
effective, permitted and inheritable sets; the limit set must
be a superset of the target's limit set; if the target process
has any uid set to 0 all privilege must be asserted unless the
effective uid is 0.
Allows a process to bind arbitrary processes to CPUs.
proc_priocntl
Allows a process to elevate its priority above its current level.
Allows a process to change its scheduling class to any scheduling class,
including the RT class.
proc_session
Allows a process to send signals or trace processes outside its
session.
proc_setid
Allows a process to set its uids at will.
Assuming uid 0 requires all privileges to be asserted.
proc_taskid
Allows a process to assign a new task ID to the calling process.
proc_zone
Allows a process to trace or send signals to processes in
other zones.
sys_acct
Allows a process to enable and disable and manage accounting through
acct(2), getacct(2), putacct(2) and wracct(2).
sys_admin
Allows a process to perform system administration tasks such
as setting node and domain name and specifying nscd and coreadm
settings.
sys_audit
Allows a process to start the (kernel) audit daemon.
Allows a process to view and set audit state (audit user ID,
audit terminal ID, audit sessions ID, audit pre-selection mask).
Allows a process to turn off and on auditing.
Allows a process to configure the audit parameters (cache and
queue sizes, event to class mappings, policy options).
sys_config
Allows a process to perform various system configuration tasks.
Allows a process to add and remove swap devices; when adding a swap
device, a process must also have sufficient privileges to read from
and write to the swap device.
sys_devices
Allows a process to successfully call a kernel module that
calls the kernel drv_priv(9F) function to check for allowed
access.
Allows a process to open the real console device directly.
Allows a process to open devices that have been exclusively opened.
sys_ipc_config
Allows a process to increase the size of a System V IPC Message
Queue buffer.
sys_linkdir
Allows a process to unlink and link directories.
sys_mount
Allows filesystem specific administrative procedures, such as
filesystem configuration ioctls, quota calls and creation/deletion
of snapshots.
Allows a process to mount and unmount filesystems which would
otherwise be restricted (i.e., most filesystems except
namefs).
A process performing a mount operation needs to have
appropriate access to the device being mounted (read-write for
"rw" mounts, read for "ro" mounts).
A process performing any of the aforementioned
filesystem operations needs to have read/write/owner
access to the mount point.
Only regular files and directories can serve as mount points
for processes which do not have all zone privileges asserted.
Unless a process has all zone privileges, the mount(2)
system call will force the "nosuid" and "restrict" options, the
latter only for autofs mountpoints.
Regardless of privileges, a process running in a non-global zone may
only control mounts performed from within said zone.
Outside the global zone, the "nodevices" option is always forced.
sys_net_config
Allows a process to configure a system's network interfaces and routes.
Allows a process to configure network parameters using ndd.
Allows a process access to otherwise restricted information using ndd.
Allows a process to push the rpcmod STREAMs module.
Allows a process to pop anchored STREAMs modules.
Allows a process to INSERT/REMOVE STREAMs modules on locations other
than the top of the module stack.
Allows a process to configure IPsec.
sys_nfs
Allows a process to perform Sun private NFS specific system calls.
Allows a process to bind to ports reserved by NFS: ports 2049 (nfs)
and port 4045 (lockd).
sys_res_config
Allows a process to create and delete processor sets, assign
CPUs to processor sets and override the PSET_NOESCAPE property.
Allows a process to change the operational status of CPUs in
the system using p_online(2).
Allows a process to configure resource pools and to bind
processes to pools
sys_resource
Allows a process to modify the resource limits specified
by setrlimit(2) and setrctl(2) without restriction.
Allows a process to exceed the per-user maximum number of
processes.
Allows a process to extend or create files on a filesystem that
has less than minfree space in reserve.
sys_suser_compat
Allows a process to successfully call a third party loadable module
that calls the kernel suser() function to check for allowed access.
This privilege exists only for third party loadable module
compatibility and is not used by Solaris proper.
sys_time
Allows a process to manipulate system time using any of the
appropriate system calls: stime, adjtime, ntp_adjtime and
the IA specific RTC calls.
