SNMP

FortiSIEM uses SNMP to discover and monitor this device. Make sure SNMP is enabled for the device as directed in its product documentation. For more information, refer to sections "Discovery Settings" and "Setting Credentials" in the User Guide.

JDBC for Database Performance Monitoring - Oracle Database Server

To configure your Oracle Database Server for performance monitoring by FortiSIEM, you must create a read-only user who has select permissions for the database. This is the user you will use to create the access credentials for FortiSIEM to communicate with your database server.

1. Open the SQLPlus application.
2. Log in with a system-level account.
3. Connect to your instance as sysdba.

   SQL> conn / as sysdba;
   Connected.

4. Create a non-admin user account. (Note: If you already created the phoenix_agent user, you can skip this step.)

   SQL> create user phoenix_agent identified by
   "accelops";
   User created.
   

5. Assign permissions to the user.

   grant select on dba_objects to phoenix_agent;

   grant select on dba_tablespace_usage_metrics to phoenix_agent;

   grant select on dba_tablespaces to phoenix_agent;

   grant select on nls_database_parameters to phoenix_agent;

   grant select on v_$backup_set to phoenix_agent;

   grant select on v_$instance to phoenix_agent;

   grant select on v_$parameter to phoenix_agent;

   grant select on v_$session to phoenix_agent;

   grant select on v_$sql to phoenix_agent;

   grant select on v_$sysmetric to phoenix_agent;

   grant select on v_$version to phoenix_agent;

   grant select on gv_$session to phoenix_agent;

   grant select on gv_$service_stats to phoenix_agent;

6. Verily that the permissions were successfully assigned to the user.

   select count(*) from dba_objects;

   select count(*) from dba_tablespace_usage_metrics;

   select count(*) from dba_tablespaces;

   select count(*) from gv$service_stats;

   select count(*) from nls_database_parameters;

   select count(*) from v$backup_set order by start_time desc;

   select count(*) from v$instance;

   select count(*) from v$parameter;

   select count(*) from v$session;

   select count(*) from v$sql;

   select count(*) from v$sysmetric;

   select count(*) from v$version;

JDBC for Database Auditing - Oracle Database Server

Required Environmental Variables

Make sure that these environment variables are set

• ORACLE_HOME= C:\app\Administrator\product\11.2.0\dbhome_1
• ORACLE_BASE= C:\app\Administrator

1. Create audit trail views by executing cataaudit.sql as the sysdb user.

   Linux:
   su- oracle
    sqlplus /nolog
    conn / as sysdba;
    @$ORACLE_HOME/rdbms/admin/cataudit.sql;
   quit
   
   Windows:
   sqlplus /nolog
   conn / as sysdba;
   @%ORACLE_HOME%/rdbms/admin/cataudit.sql;
   quit

2. Enable auditing by modifying the Oracle instance initialization file init<SID>.ora.
This is typically located in $ORACLE_BASE/admin/<SID>/pfile where DIS is the Oracle instance

   AUDIT_TRAIL = DB 
   or 
   AUDIT_TRAIL = true

3. Restart the database.

   su - oracle
    sqlplus /nolog
    conn / as sysdba;
    shutdown immediate;
    startup;
    quit

4. Create a user account and grant select privileges to that user.

   su - oracle
    sqlplus /nolog
    conn / as sysdba
    Create user phoenix_agent identified by "phoenix_agent_pwd"   (NOTE: please correct this set -- above steps showed that we created phoenix_agent already, just add the grant steps and utilize the "accelops" password;
    Grant connect to phoenix_agent;
    Grant select on dba_audit_trail to phoenix_agent;
    Grant select on v_$session to phoenix_agent;

5. Turn on auditing.

   su - oracle
   sqlplus /nolog
   conn / as sysdba;
   audit session;
   quit;

6. Fetch the audit data to make sure the configuration was successful.

   su - oracle;
    sqlplus phoenix_agent/phoenix_agent_pwd;
    select count (*) from dba_audit_trail;

   
   You should see the count changing after logging on a few times.
   

Configuring Listener Log and Error Log via SNARE - Oracle Side

1. Install and configure Epilog application to send syslog to FortiSIEM
   1. Download Epilog from snare, information to download here, and install it on your Windows Server.
   2. Launch Epilog from Start→All Programs→InterSect Alliance→Epilog for windows
   3. Configure Epilog application as follows
      1. Select Log Configuration on left hand panel, click Add button to add Oracle Listener log file to be sent to FortiSIEM. Also make sure the Log Type is OracleListenerLog.
         
      2. Click Add button to add Oracle Alert log file to be sent to FortiSIEM. Also make sure the Log Type is OracleAlertLog.
         
      3. After adding both the files, SNARE Log Configuration will show both the files included as follows
         
      4. Select Network Configuration on left hand panel. On the right, set the destination address to that of FortiSIEM server, port to 514 and make sure that syslog header is enabled. Then click Change Configuration button.
         
      5. Click the "Apply the latest audit configuration" link on the left hand side to apply the changes to Epilog applications. DHCP logs will now sent to FortiSIEM in real time.
         

You can now configure FortiSIEM to communicate with your device. For more information, refer to sections "Discovery Settings" and "Setting Credentials" in the User Guide.
