Applying Service Pack and Signature Updates
The Update page enables you to immediately apply service pack and signature updates.
Note The sensor cannot download service pack and signature updates from Cisco.com. You must download the service pack and signature updates from Cisco.com to your FTP server, and then configure the sensor to download them from your FTP server.
See Supported FTP Servers, for a list of supported servers.
To immediately apply a service pack and signature update, follow these steps:
Step 1 Select Administration > Update.
The Update page appears.
Figure 5-3 Update Page
Step 2 In the URL field, enter the URL where the update can be found.
For example:
URL: ftp://user@10.1.1.1/UPDATES/IDS-K9-sp-4.0-1.1-S36-0.1-.rpm.pkg
Note You must have already downloaded the update from Cisco.com and put it on the FTP server.
Step 3 In the Password field, enter the particular transport protocol password.
Note You can use the following transport protocols: SCP, FTP, HTTP, or HTTPS.
Note To reset the form, click Reset.
Step 4 Click Apply to Sensor to apply the update.
Note To schedule regular updates, see Configuring Automatic Updates.
Configuring IP Logging
You can configure the sensor to catch all IP traffic associated with the hosts you specify by IP address.
Note IP Logging requires that event logging be enabled with Informational as the severity level. See Configuring Signatures, for more information.
To generate logs files for specific IP addresses, follow these steps:
Step 1 Select Administration > IP Logging.
The Ip Logging Configuration page appears.
Figure 5-4 Ip Logging Configuration Page
Step 2 Click Add to add the IP addresses of the hosts whose IP traffic you want to log.
The Adding page appears.
Figure 5-5 Adding Page
Step 3 In the IP address field, enter the source IP address of the host whose IP traffic you want to log.
Step 4 In the Duration field, enter the number of minutes you want to the sensor to log IP traffic (optional).
Step 5 In the Number of Packets field, enter the number of packets you want the sensor to count (optional).
Step 6 In the Number of Bytes field, enter the number of bytes you want to log (optional).
Note To reset the form, click Reset.
Step 7 Click Apply to Sensor to save your changes.
The Ip Logging Configuration page now displays the new Log ID.
Note The sensor begins logging and creates a log file that you can view by selecting Monitoring > IP Logs. See Downloading IP Logs, for more information.
Step 8 To discontinue logging IP traffic, select the check box next to the log ID, and then click Stop.
Note The IP log is overwritten when the sensor uses up its allocated space for IP logging.
Blocking Hosts Manually
On occasion, you may want to block a host for a short time. From the Host Manual Blocks page, you can configure which host is blocked and for how long, and you can view a list of hosts that are being blocked.
To set up the manual blocking of a host, follow these steps:
Step 1 Select Administration > Manual Blocking > Host Manual Blocks.
The Host Manual Blocks page appears.
Figure 5-6 Host Manual Blocks Page
Step 2 Click Add to add a host to block.
The Adding Page appears.
Figure 5-7 Adding Page
Step 3 In the Source Address field, enter the IP address of the host you want to block.
Step 4 In the Source Port field, enter the port you want to use to block the host (optional).
Step 5 In the Destination Address field, enter the destination address (optional).
Step 6 From the Protocol list box, select one of these options (optional):
•None
•tcp
•udp
Step 7 Select the Connection Shun check box to block only those connections that have the source IP address, destination IP address, destination port, or protocol specified (optional).
Note If you select the Connection Shun check box, the attacking host is free to connect to other hosts or to other services on the protected host. If destination port and protocol are not specified, the attacking host cannot send packets to the protected host at all, but can access other hosts on the network.
Step 8 In the Timeout field, enter the number of minutes you want the block to last.
Note To create a permanent block, enter -1.
Note To reset the form, click Reset.
