Follow the usage guidelines to run additional Cytool commands.

List processes protected by Traps.

Enter the

cytool enum

command.

root@ubuntu:~$ 
cytool
enum
-----------------------------------
Traps list of protected processes:
-----------------------------------
  PID CMD                           UID
 1098 /usr/sbin/cron -f               0
 1131 /usr/sbin/rsyslogd -n         104

To view processes for all users including those initiated by the operating system, specify the

/a

option.

Start or stop Traps daemons.

The Traps agent comprises the trapsd, authorized, and pmd daemons. To start or stop one or all daemons, enter either the

cytool runtime [start | stop] [

<process_name>

| all]

command or the

cytool startup [enable | disable] [

<process_name>

| all]

command. The behavior of both commands changes both the current running state and the startup registration status of the daemons when the server boots.

For example:

root@ubuntu:~$ 
/opt/traps/bin/cytool
runtime stop trapsd
         Name    PID       User       Status       Command
       trapsd    N/A       N/A        STOPPED      N/A
   authorized   2179       root       Running      /opt/traps/bin/authorized
          pmd   2164       root       Running      /opt/traps/bin/pmd
root@ubuntu:~$ 
/opt/traps/bin/cytool runtime start all
         Name    PID       User       Status       Command
       trapsd  26427       root       Running      /opt/traps/bin/trapsd
   authorized   2179       root       Running      /opt/traps/bin/authorized
          pmd   2164       root       Running      /opt/traps/bin/pmd

View the Traps security policy.

Traps stores policy and security event information such as the list of trusted signers, local verdicts, and one-time actions in local databases in the

/opt/traps/persist/

directory. To troubleshoot policy issues and security events, you can use Cytool to import, export, and view information stored in the local database.

To view a list of all local databases, use the

cytool persist list

command.

root@ubuntu:~$ 
/opt/traps/bin/cytool
persist list
Persistent database list:
      post_detection.db      Database of post-detection candidates
       agent_actions.db      Database of one time actions
      cloud_frontend.db      Database of Cloud frontend settings
          hashes_lru.db      Least recently used verdicts database
       cloud_reports.db      Database of Cloud reports
              hashes.db      Database of the verdicts received from WildFire
        esm_frontend.db     Database of ESM frontend settings
              policy.db      Policy database
              fvhash.db      Database of blacklisted fvhashes
     trusted_signers.db      Database of trusted signers
          hash_paths.db      Database of file paths
       hash_override.db      Database of hashes override (Admin exeptions)
         esm_reports.db      Database of ESM reports
     security_events.db      Database of security events (preventions)
         file_upload.db      Database of files being uploaded to ESM
   hashes_retransmit.db      Database of hashes to be retransmitted
      agent_settings.db      Database of agent settings

To view the records of a database, use the

cytool persist print [

<database_name>

|

<database_path>

]

command where you specify either the name of database (see the

cytool persist list

command) or the path to the database. Or, to export the records of a database to a JSON file, use the

cytool persist export [

<database_name>

|

<database_path>

]

command. For example:

root@ubuntu:~$ 
/opt/traps/bin/cytool
persist print security_events.db

To add records to the database, use the

cytool persist import [

<database_name>

|

<database_path>

]

<input_filename>

command where

<input_filename>

is a JSON file.

Collect logs.

Use the

cytool log

<log_level>

[

<process_name>

| all]

command to change the log level of a Traps component where:

<log_level>
is an integer value corresponding to the log level:
1—Fatal
2—Critical
3—Error
4—Warning
5—Notice
6—Information
7—Debug
8—Trace
<process_name>
is the traps component:
trapsd
,
authorized
, or
pmd
.

Then use the

cytool log collect

command to collect all logs in a TGZ file.

root@ubuntu:~$ 
/opt/traps/bin/cytool log
1 trapsd
root@ubuntu:~$ 
/opt/traps/bin/cytool log collect
-rw-r--r-- 1 root root 1651939 Dec 30 20:33 /tmp/Traps_log_2017-12-30_20-33-22/Traps_log_2017-12-30_20-33-22.tgz

Manually initiate a check in with the server.

Use the

cytool checkin

command to initiate the manual check-in. To verify the status of the check-in on the Traps management service, view the

LAST SEEN

date from the additional details view of an endpoint on the

Endpoints

page.

Configure proxy communication.

If defined, the Traps agent uses the proxy settings defined in the system environment in

/etc/environment

. If proxy settings are not defined, you can add the proxy server to the system environment by specifying the following setting in the

environment

file:

https_proxy=”https://
<proxyserver>:
<port>"

where:

<proxyserver>
is the IP address of the proxy server
<port>
is the port number used for proxy communication.

For example:

https_proxy="https://10.196.20.244:8080"
