Add and Edit Device List Dialog Boxes Field Definitions

Sensor Name—Name of the sensor you are adding.

Sensor IP Address—IP address of the sensor you are adding.

Web Server Port—TCP port used by the Web Server.

The default is 443 for HTTP or HTTPS. You receive an error message if you enter a value out of the range of 1 to 65535.

Communication Protocol—Enables TLS and SSL in the Web Server.

The default is Use encrypted connection (HTTPS). We strongly recommend that you use an encrypted connection.

Authentication—Lets you specify separate credentials for configuration and event subscription.

Configuration User Name—Name of user account allowed to configure this sensor.

Configuration Password—Password of the user account allowed to configure this sensor.

Use the Same Account for Configuration and Event Subscription (This is not recommended)—Lets you have the same account apply to users who can configure and monitor the sensor.


Caution Using the same credentials for both configuration and event retrieval is not as secure as maintaining separate user accounts. We recommend that you maintain separate accounts and that the configuration username have an administrator user role and the event subscription username have a viewer user role.

Event Subscription User Name—Name of user account allowed to view events on this sensor.

Event Subscription Password—Password of the user account allowed to view events on this sensor.

Event Start Time (UTC)—Lets you choose to have the most recent alerts retrieved or you can select the start date and time of alerts to retrieve.

Exclude alerts of the following severity level(s)—Lets you choose to exclude security levels from retrieval. The default is for all security levels to be displayed.

Adding, Editing, and Deleting Devices

To add, edit, and delete devices, follow these steps:


Step 1 Choose Home > Devices > Device List, and then click Add.

Step 2 Fill in the required fields in the Add Device dialog box:

a. Enter the sensor name and sensor IP address of the sensor you are adding.

b. To change the default web server port, enter a new port number.

c. Choose the communication protocol.


Note We strongly recommend that you use an encrypted connection.


d. Enter the username and password of the account that will configure this sensor.

e. Enter the username and password of the person who will monitor the event subscription for this sensor.


Caution Using the same credentials for both configuration and event retrieval is not as secure as maintaining separate user accounts. We recommend that you maintain separate accounts and that the configuration username have an administrator user role and the event subscription username have a viewer user role.

f. Choose the event start time by either checking the Latest Alerts check box or entering a start date and time in the Start Date and Start Time fields.

g. Under Exclude alerts of the following severity level(s), check the check boxes of any levels you want to exclude.

The default is to have all the levels configured.

h. Click OK to add the sensor to the IME system.

Step 3 Click Yes to accept the certificate and continue the HTTPS connection with the sensor.


Note If you click No you reject the certificate and IME cannot connect to the sensor.


IME checks the time setting between IME and the sensor to make sure it is correct. If it is not, you receive a warning message if the sensor time and the IME system are more than five minutes apart. Make sure you synchronize the sensor with your system.


Caution Having the correct time is important so that reports, historical events, and the top gadgets are accurate. If the time is not within the range of five minutes, an icon appears next to the device in the Device Lists pane.

Step 4 To edit a device, select it in the list, click Edit, make any changes needed, and then click OK.


Note You cannot change the Sensor Name because it is a key for the IME database.


Step 5 To delete a device, select it in the list, and then click Delete.

The device no longer appears in the Device List pane.


For More Information

For information on correcting time on the sensor, see Correcting Time on the Sensor.

Starting, Stopping, and Displaying Device, Event, Health, and Global Correlation Connection Status

IME queries the sensor every 10 seconds to obtain health status information as long as you choose Start > Health Connection. IME pulls alerts from the sensor as long as you choose Start  > Events Connection. IME sends and receives global correlation data as long as you choose Start  > Global Correlation Connection.

There are some situations in which you might want to stop the sensor from polling events. For example, you can stop polling events from a specific sensor if you do not want its real-time events interfering when you are analyzing the events of another sensor. Then you can resume after the polling is done. Or you can stop polling health and security if you want to look at a snapshot of the status without the 10-second update.

To start, stop, and display event, health, and global correlation connection status, follow these steps:


Step 1 Select the sensor in the device list for which you want to start or stop event, health, or global correlation connection status.

Step 2 Choose Start or Stop > Health Connection or Events Connection or Global Correlation Connection.

The column now reads Connected or Not Connected.

Step 3 To display the connection status of IME to the sensor, the sensor version, and statistics information, select the sensor in the list, and then click Status.

The following IPS component statistics are displayed in the Device Status dialog box:

Analysis Engine

Anomaly Detection

Event Store

External Product Interface

Using Tools for Devices

You can use ping to diagnose basic network connectivity. Ping is a simple way to check if a sensor can communicate back. You can use traceroute to display the route an IP packet takes to a destination. You can use whois to determine the owner of a domain name or an IP address. You can use DNS lookup to translate host names to IP addresses, rather like a phone book.

To use tools for devices, follow these steps


Step 1 Choose Home > Devices.

Step 2 To obtain ping statistics for a sensor, select it in the device list table, and then click Tools > Ping.

The Executing command - ping dialog box displays the ping statistics for that sensor.

Step 3 To find the route of the IP packet, select the sensor in the list, and then click Tools > Traceroute.

The Executing command - traceroute dialog box displays the trace route statistics for that sensor.

Step 4 To find the whois information, select the sensor in the list, and then click Tools > WhoIs.

The Executing command - whois dialog box displays the WHOIS statistics for that sensor.

Step 5 To find the DNS information, select the sensor in the list, and then click Tools > DNS.

The Executing command - nslookup dialog box displays the DNS lookup statistics for that sensor.
