The following HTTP/HTTPS servers are supported for IPS software updates:

CSM - Apache Server (Tomcat)

ROMMON and TFTP

ROMMON uses TFTP to download an image and launch it. TFTP does not address network issues such as latency or error recovery. It does implement a limited packet integrity check so that packets arriving in sequence with the correct integrity value have an extremely low probability of error. But TFTP does not offer pipelining so the total transfer time is equal to the number of packets to be transferred times the network average RTT. Because of this limitation, we recommend that the TFTP server be located on the same LAN segment as the sensor. Any network with an RTT less than a 100 milliseconds should provide reliable delivery of the image. Be aware that some TFTP servers limit the maximum file size that can be transferred to ~32 MB.

IPS Management and Event Viewers

For More Information

For the procedure to apply IPS 7.1(7)E4 to sensors using CSM 4.3 SP1 or later, see Applying IPS 7.1(7)E4 to sensors using CSM 4.3 SP1 or Later.

New and Changed Information

Cisco IPS 7.1(7)E4 contains the following new and changed information:

IDM 7.1.7.

Signature update S691.

Continuing support for the IPS 4240, IPS 4255, IPS 4260, ASA 5500 AIP SSM series, IPS 4270-20, IPS 4345, IPS 4360, ASA 5585-X IPS SSP series, and ASA 5500-X IPS SSP series.

The default value of the Cisco server IP address has been changed from 198.133.219.25 to 72.163.4.161 in the Auto Update URL configuration. If you have automatic update configured on your sensor, you may need to update your firewall rules to allow sensor connectivity to this new IP address.

IPS 7.1(7)E4 reverses the SMB protocol-related inspection enhancements delivered as part of the IPS 7.1(5)E4 release and also addresses a signature downgrade issue with ASA 5500 AIP SSM platforms.

IPS 7.1(7)E4 deprecates the use of licenses for versions 6.0.x or earlier. Obtain new licenses for versions 6.0.x and later and apply to your sensor before upgrading to IPS 7.1(7)E4. You can obtain licenses at this URL:

http://www.cisco.com/go/license

For More Information

For the procedure for obtaining and installing the license, see Licensing the Sensor.

The Sensor and Jumbo Packet Frame Size

For IPS standalone appliances with 1 G and 10 G fixed or add-on interfaces, the maximum jumbo frame size is 9216 bytes. For integrated IPS sensors, such as the ASA 5500-X and ASA 5585-X series, refer to the following URL for information:

http://www.cisco.com/en/US/docs/security/asa/asa84/configuration/guide/interface_start.html#wp1328869


Note A jumbo frame is an Ethernet packet that is larger than the standard maximum of 1518 bytes (including Layer 2 header and FCS).


The ASA IPS Modules and Jumbo Packets

The jumbo packet count in the show interface command output from the lines Total Jumbo Packets Received and Total Jumbo Packets Transmitted for ASA IPS modules may be larger than expected due to some packets that were almost jumbo size on the wire being counted as jumbo size by the IPS. This miscount is a result of header bytes added to the packet by the ASA before the packet is transmitted to the IPS. For IPv4, 58 bytes of header data are added. For IPv6, 78 bytes of header data are added. The ASA removes the added IPS header before the packet leaves the ASA.

Obtaining Software

You can find major and minor updates, service packs, signature and signature engine updates, system and recovery files, firmware upgrades, and Readmes on the Download Software site on Cisco.com.

Upgrade Notes and Caveats

Upgrading the Sensor

Upgrade Notes and Caveats

Pay attention to the following upgrade notes and caveats when upgrading to IPS 7.1(7)E4:

You cannot upgrade to 7.1(7)E4 the sensor license was generated for 6.0.x versions and earlier. The upgrade fails and the follwoing message is displayed:

Error: execUpgradeSoftware : This license is a IPS version 6.0 or earlier license 
which is not compatible with platforms running 7.1.X IPS Versions. Please install a 
IPS version 6.1 or later license type. Refer to 7.1.X IPS version README or IPS 
documents for the details of generating a new license. 
 
   

The default value of the Cisco server IP address has been changed from 198.133.219.25 to 72.163.4.161 in the Auto Update URL configuration. If you have automatic update configured on your sensor, you may need to update firewall rules to allow the sensor to connect to this new IP address.

If you are upgrading the IPS 4270-20 and you have a license for 6.0.x and earlier, you receive the following error message:

Currently installed License is not valid in 7.1(7). Install a license that is 
applicable for IPS versions 6.1 and above.
 
   

You must get a new license before upgrading your IPS 4270-20.

Anomaly detection has been disabled by default. If you did not configure the operation mode manually before the upgrade, it defaults to inactive after you upgrade to IPS 7.1(7)E4. If you configured the operation mode to detect, learn, or inactive, the tuned value is preserved after the upgrade.

You must have a valid maintenance contract per sensor to download software upgrades from Cisco.com.

You must be running the following versions to upgrade the following platforms to IPS 7.1(7)E4:

For the IPS 4200 series sensors, you must be running IPS 6.0(6)E4 or later.

For the IPS 4300 series sensors and the ASA 5500-X IPS SSP series, you must be running IPS 7.1(3)E4 or later.

For the IPS 4500 series sensors, you must be running IPS 7.1(4)E4 or later.

For the ASA 5500 AIP SSM series, you must be running IPS 6.0(6)E4 or later.

For the ASA 5585-X IPS SSP series, you must be running IPS 7.1(1)E4 or later.

A generic upgrade package is no longer available for the IPS 4240, IPS 4255, IPS 4260, and ASA 5500 AIP SSM series. These platforms now have platform-specific filenames in accordance with the 7.1(x) format.

This service pack automatically reboots the sensor to apply the changes. During reboot, inline network traffic is disrupted.

You cannot uninstall 7.1(7)E4. To revert to a previous version, you must reimage the sensor using the appropriate system image file

Understanding Initialization


Note You must be administrator to use the setup command.


After you install the sensor on your network, you must use the setup command to initialize it so that you can communicate with it over the network. You cannot use the IDM or the IME to configure the sensor until you initialize the sensor using the setup command.

With the setup command, you configure basic sensor settings, including the hostname, IP interfaces, access control lists, global correlation servers, and time settings. You can continue using advanced setup in the CLI to enable Telnet, configure the web server, and assign and enable virtual sensors and interfaces, or you can use the Startup Wizard in the IDM or the IME. After you configure the sensor with the setup command, you can change the network settings in the IDM or the IME.


Caution You must have a valid sensor license for global correlation features to function. You can still configure and display statistics for the global correlation features, but the global correlation databases are cleared and no updates are attempted. Once you install a valid license, the global correlation features are reactivated.

Simplified Setup Mode

The sensor automatically calls the setup command when you connect to the sensor using a console cable and the sensor basic network settings have not yet been configured. The sensor does not call automatic setup under the following conditions:

When initialization has already been successfully completed.

If you have recovered or downgraded the sensor.

If you have set the host configuration to default after successfully configuring the sensor using automatic setup.

When you enter the setup command, an interactive dialog called the System Configuration Dialog appears on the system console screen. The System Configuration Dialog guides you through the configuration process. The values shown in brackets next to each prompt are the default values last set.

System Configuration Dialog

When you enter the setup command, an interactive dialog called the System Configuration Dialog appears on the system console screen. The System Configuration Dialog guides you through the configuration process. The values shown in brackets next to each prompt are the current values.

You must go through the entire System Configuration Dialog until you come to the option that you want to change. To accept default settings for items that you do not want to change, press Enter.

To return to the EXEC prompt without making changes and without going through the entire System Configuration Dialog, press Ctrl-C. The System Configuration Dialog also provides help text for each prompt. To access the help text, enter ? at a prompt.

When you complete your changes, the System Configuration Dialog shows you the configuration that you created during the setup session. It also asks you if you want to use this configuration. If you enter yes, the configuration is saved. If you enter no, the configuration is not saved and the process begins again. There is no default for this prompt; you must enter either yes or no.

You can configure daylight savings time either in recurring mode or date mode. If you choose recurring mode, the start and end days are based on week, day, month, and time. If you choose date mode, the start and end days are based on month, day, year, and time. Choosing disable turns off daylight savings time.


Note You only need to set the date and time in the System Configuration Dialog if the system is an appliance and is NOT using NTP.



Note The System Configuration Dialog is an interactive dialog. The default settings are displayed.

Basic Sensor Setup

To perform basic sensor setup using the setup command, follow these steps:


Step 1 Log in to the sensor using an account with administrator privileges.


Note Both the default username and password are cisco.


Step 2 The first time you log in to the sensor you are prompted to change the default password. Passwords must be at least eight characters long and be strong, that is, not be a dictionary word. After you change the password, basic setup begins.

Step 3 Enter the setup command. The System Configuration Dialog is displayed.

Step 4 Specify the hostname. The hostname is a case-sensitive character string up to 64 characters. Numbers, "_" and "-" are valid, but spaces are not acceptable. The default is sensor.

Step 5 Specify the IP interface. The IP interface is in the form of IP Address/Netmask,Gateway: X.X.X.X/nn,Y.Y.Y.Y, where X.X.X.X specifies the sensor IP address as a 32-bit address written as 4 octets separated by periods, nn specifies the number of bits in the netmask, and Y.Y.Y.Y specifies the default gateway as a 32-bit address written as 4 octets separated by periods.

Step 6 Enter yes to modify the network access list:

a. If you want to delete an entry, enter the number of the entry and press Enter, or press Enter to get to the Permit line.

b. Enter the IP address and netmask of the network you want to add to the access list.


Note For example, 10.0.0.0/8 permits all IP addresses on the 10.0.0.0 network (10.0.0.0-10.255.255.255) and 10.1.1.0/24 permits only the IP addresses on the 10.1.1.0 subnet (10.1.1.0-10.1.1.255). If you want to permit access to a single IP address than the entire network, use a 32-bit netmask. For example, 10.1.1.1/32 permits just the 10.1.1.1 address.


c. Repeat Step b until you have added all networks that you want to add to the access list, and then press Enter at a blank permit line to go to the next step.

Step 7 You must configure a DNS server or an HTTP proxy server for global correlation to operate:

a. Enter yes to add a DNS server, and then enter the DNS server IP address.

b. Enter yes to add an HTTP proxy server, and then enter the HTTP proxy server IP address and port number.


Caution You must have a valid sensor license for global correlation features to function. You can still configure and display statistics for the global correlation features, but the global correlation databases are cleared and no updates are attempted. Once you install a valid license, the global correlation features are reactivated.

Step 8 Enter yes to modify the system clock settings:

a. Enter yes to modify summertime settings.


Note Summertime is also known as DST. If your location does not use Summertime, go to Step m.


b. Enter yes to choose the USA summertime defaults, or enter no and choose recurring, date, or disable to specify how you want to configure summertime settings. The default is recurring.

c. If you chose recurring, specify the month you want to start summertime settings. Valid entries are january, february, march, april, may, june, july, august, september, october, november, and december. The default is march.

d. Specify the week you want to start summertime settings. Valid entries are first, second, third, fourth, fifth, and last. The default is second.

e. Specify the day you want to start summertime settings. Valid entries are sunday, monday, tuesday, wednesday, thursday, friday, and saturday. The default is sunday.

f. Specify the time you want to start summertime settings. The default is 02:00:00.


Note The default recurring summertime parameters are correct for time zones in the United States. The default values specify a start time of 2:00 a.m. on the second Sunday in March, and a stop time of 2:00 a.m. on the first Sunday in November. The default summertime offset is 60 minutes.


g. Specify the month you want summertime settings to end. Valid entries are january, february, march, april, may, june, july, august, september, october, november, and december. The default is november.

h. Specify the week you want the summertime settings to end. Valid entries are first, second, third, fourth, fifth, and last. The default is first.

i. Specify the day you want the summertime settings to end. Valid entries are sunday, monday, tuesday, wednesday, thursday, friday, and saturday. The default is sunday.

j. Specify the time you want summertime settings to end. The default is 02:00:00.

k. Specify the DST zone. The zone name is a character string up to 24 characters long in the pattern [A-Za-z0-9()+:,_/-]+$.

l. Specify the summertime offset. Specify the summertime offset from UTC in minutes (negative numbers represent time zones west of the Prime Meridian). The default is 60.

m. Enter yes to modify the system time zone.

n. Specify the standard time zone name. The zone name is a character string up to 24 characters long.

o. Specify the standard time zone offset. Specify the standard time zone offset from UTC in minutes (negative numbers represent time zones west of the Prime Meridian). The default is 0.

p. Enter yes if you want to use NTP. To use authenticated NTP, you need the NTP server IP address, the NTP key ID, and the NTP key value. If you do not have those at this time, you can configure NTP later. Otherwise, you can choose unauthenticated NTP.

Step 9 Enter off, partial, or full to participate in the SensorBase Network Participation:

Off—No data is contributed to the SensorBase Network.

Partial—Data is contributed to the SensorBase Network, but data considered potentially sensitive is filtered out and never sent.

Step 4 Write down the certificate fingerprints. You need the fingerprints to check the authenticity of the certificate when connecting to this sensor with a web browser.


Logging In to the IDM

The IDM is a web-based, Java Web Start application that enables you to configure and manage your sensor. The web server for the IDM resides on the sensor. You can access it through Internet Explorer or Firefox web browsers.


Note The IDM is already installed on the sensor.


To log in to the IDM, follow these steps:


Step 1 Open a web browser and enter the sensor IP address. A Security Alert dialog box appears.

https://sensor_ip_address
 
   

Note The default IP address is 192.168.1.2/24,192.168.1.1, which you change to reflect your network environment when you initialize the sensor. When you change the web server port, you must specify the port in the URL address of your browser when you connect to the IDM in the format https://sensor_ip_address:port (for example, https://192.0.2.1:1040).


Step 2 Click Yes to accept the security certificate. The Cisco IPS Device Manager Version window appears.

Step 3 To launch the IDM, click Run IDM. The JAVA loading message box appears, and then the Warning - Security dialog box appears.

Step 4 To verify the security certificate, check the Always trust content from this publisher check box, and click Yes. The JAVA Web Start progress dialog box appears, and then the IDM on ip_address dialog box appears.

Step 5 To create a shortcut for the IDM, click Yes. The Cisco IDM Launcher dialog box appears.


Note You must have JRE 1.5 (JAVA 5) installed to create shortcuts for the IDM. If you have JRE 1.6 (JAVA 6) installed, the shortcut is created automatically.


Step 6 To authenticate the IDM, enter your username and password, and click OK. Both the default username and password are cisco. You were prompted to change the password during sensor initialization. The IDM begins to load. If you change panes from Home to Configuration or Monitoring before the IDM has completed initialization, a Status dialog box appears with the following message:

Please wait while IDM is loading the current configuration from the sensor.
 
   

The main window of the IDM appears.


Note If you created a shortcut, you can launch the IDM by double-clicking the IDM shortcut icon. You can also close the The Cisco IPS Device Manager Version window. After you launch the IDM, it is not necessary for this window to remain open.



Installing or Upgrading the IME

This section describes how to install and upgrade the IME, and how to migrate data from IEV or a previous version of IME.

Cisco IEV, Cisco IOS IPS, and CSM

If you have a version of Cisco IPS Event Viewer installed, the Install wizard prompts you to remove it before installing the IME.

The IME event monitoring is also supported in IOS-IPS versions that support the Cisco IPS 5.x/6.x signature format. We recommend IOS-IPS 12.4(15)T4 if you intend to use the IME to monitor an IOS IPS device. Some of the new IME functionality including health monitoring is not supported.


Caution Do not install the IME on top of existing installations of CSM. You must uninstall CSM before installing the IME.

Installation Notes and Caveats


Note If you are using Windows 7 or Windows Server 2008, and an IME version earlier than 7.1.1, uninstall IME before upgrading it. Otherwise, just upgrade from your current IME version.


Observe the following when installing or upgrading the IME:

You can install the IME over all versions of the IME but not over IEV. All alert database and user settings are preserved.

The IME detects previous versions of IEV and prompts you to manually remove the older version before installing the IME or to install the IME on another system. The installation program then stops.

Make sure you close any open instances of the IME before upgrading to a new version of the IME.

Disable any anti-virus or host-based intrusion detection software before beginning the installation, and close any open applications. The installer spawns a command shell application that may trigger your host-based detection software, which causes the installation to fail.

You must be administrator to install the IME.

The IME coexists with other instances of the MySQL database. If you have a MySQL database installed on your system, you do NOT have to uninstall it before installing the IME.

Installing or Upgrading the IME

To install the IME, follow these steps:


Step 1 From the Download Software site on Cisco.com, download the IME executable file to your computer, or start the IDM in a browser window, and under Cisco IPS Manager Express, click download to install the IME executable file. IME-7.2.2.exe is an example of what the IME executable file might look like.

Step 2 Double-click the executable file. The Cisco IPS Manager Express - InstallShield Wizard appears. You receive a warning if you have a previous version of Cisco IPS Event Viewer installed. Acknowledge the warning, and exit installation. Remove the older version of IEV, and then continue the IME installation

Step 3 Click Next to start the IME installation.

Step 4 Accept the license agreement and click Next.

Step 5 Click Next to choose the destination folder, click Install to install the IME, and then click Finish to exit the wizard. The Cisco IME and Cisco IME Demo icons are now on your desktop.


Note The first time you start the IME, you are prompted to set up a password.



Migrating IEV Data

To migrate IEV 5.x events to the IME, you must exit the installation and manually export the old events by using the IEV 5.x export function to move the data to local files. After installing the IME, you can import these files to the new IME system.


Note The IME does not support import and migration functions for IEV 4.x.


To export event data from IEV 5.x to a local file:


Step 1 From IEV 5.x, choose File > Database Administration > Export Database Tables.

Step 2 Enter the file name and select the table(s).

Step 3 Click OK. The events in the selected table(s) are exported to the specified local file.


Importing IEV Event Data In to IME

To import event data in to the IME, follow these steps:


Step 1 From the IME, choose File > Import.

Step 2 Select the file exported from IEV 5.x and click Open. The contents of the selected file are imported in to the IME.


For More Information

For more information about the IME, refer to Cisco Intrusion Prevention System Manager Express Installation Guide for IPS 7.1.

Enabling Anomaly Detection


Note Anomaly detection is disabled by default in IPS 7.1(2)E4 and later. You must enable it to configure or apply an anomaly detection policy. Enabling anomaly detection results in a decrease in performance.


The following section explains how to enable anomaly detection through the IDM, IME, and the CLI. It contains the following topics:

Enabling Anomaly Detection Using the IDM or IME

Enabling Anomaly Detection Using the CLI

Enabling Anomaly Detection Using the IDM or IME

To enable anomaly detection, follow these steps:


Step 1 Log in to the IDM or IME using an account with administrator or operator privileges.

For More Information

For more detailed information about anomaly detection, refer to Configuring Anomaly Detection.

Disabling Anomaly Detection Using the CLI

If you have anomaly detection enabled and you have your sensor configured to see only one direction of traffic, you should disable anomaly detection. Otherwise, you will receive many alerts, because anomaly detection sees asymmetric traffic as having incomplete connections, that is, like worm scanners, and fires alerts.

To disable anomaly detection, follow these steps:


Step 1 Log in to the CLI using an account with administrator privileges.

Step 2 Enter analysis engine submode.

sensor# configure terminal
sensor(config)# service analysis-engine
sensor(config-ana)#
 
   

Step 3 Enter the virtual sensor name that contains the anomaly detection policy you want to disable.

sensor(config-ana)# virtual-sensor vs0
sensor(config-ana-vir)# 
 
   

Step 4 Disable anomaly detection operational mode.

sensor(config-ana-vir)# anomaly-detection
sensor(config-ana-vir-ano)# operational-mode inactive
sensor(config-ana-vir-ano)# 
 
   

Step 5 Exit analysis engine submode.

sensor(config-ana-vir-ano)# exit
sensor(config-ana-vir)# exit
sensor(config-ana-)# exit
Apply Changes:?[yes]:
 
   

Step 6 Press Enter to apply your changes or enter no to discard them.

Restrictions and Limitations

The following restrictions and limitations apply to Cisco IPS 7.1(7)E4 software and the products that run it:

The IPS 4345 and IPS 4360 do not support hardware bypass. Hardware bypass is currently only supported on the IPS 4270-20.

The 4240, IPS 4255, IPS 4260, IPS 4270, ASA 5500 AIP SSM, ASA 5512-X IPS SSP, and the ASA 5515-X IPS SSP do not support the Regex accelerator card and the String XL engines.

Applying any signature template erases any existing tunings associated with the targeted signature definition file. The IPS 4240, IPS 4255, IPS 4260, IPS 4270-20, ASA 5500 AIP SSM, ASA 5512-X IPS SSP, and ASA 5515-X IPS SSP do not support signature templates (signature threat profiles).

The IPS 4240, IPS 4255, IPS 4260, IPS 4270-20, ASA 5500 AIP SSM, ASA 5512-X IPS SSP, and ASA 5515-X IPS SSP do not support HTTP advanced decoding.

In IPS 7.1, rx/tx flow control is disabled on the IPS 4200 series sensors. This is a change from IPS 7.0 where rx/tx flow control is enabled by default.

Enabling HTTP advanced decoding can have a significantly negative performance and memory impact on the sensor.

Use the show statistics virtual-sensor | include load command (CLI) or look at the statistics for the virtual sensor at Configuration > Sensor Monitoring > Support Information > Statistics (IDM/IME) to determine the load value over a longer period of time. The show statistics analysis-engine command (CLI) and the statistics for Analysis Engine show values over a shorter period of time. If you compare the output, the values will appear to be inconsistent due to the different time periods. To get an accurate comparison between them, compare the processing load percentage from the statistics for the virtual sensor and the one-minute averaged value from the statistics for Analysis Engine.CSCtq35258

On IPS sensors with multiple processors (for example, the IPS 4260 and IPS 4270-20), packets may be captured out of order in the IP logs and by the packet command. Because the packets are not processed using a single processor, the packets can become out of sync when received from multiple processors.

TACACS+ authentication is not supported in IPS 7.1(7)E4.

The CLI timeout feature is applicable only for sessions established through SSH, Telnet, and the console. Service account logins are not affected.

Anomaly detection does not support IPv6 traffic; only IPv4 traffic is directed to the anomaly detection processor.

IPv6 does not support the following event actions: Request Block Host, Request Block Connection, or Request Rate Limit.

Global correlation does not support IPv6.

There is no support for IPv6 on the management (command and control) interface.

ICMP signature engines do not support ICMPv6, they are IPv4-specific, for example, the Traffic ICMP signature engine. ICMPv6 is covered by the Atomic IP Advanced signature engine.

CSM and MARS do not support IPv6.

When deploying an IPS sensor monitoring two sides of a network device that does TCP sequence number randomization, we recommend using a virtual senor for each side of the device.

For IPS 5.0 and later, you can no longer remove the cisco account. You can disable it using the no password cisco command, but you cannot remove it. To use the no password cisco command, there must be another administrator account on the sensor. Removing the cisco account through the service account is not supported. If you remove the cisco account through the service account, the sensor most likely will not boot up, so to recover the sensor you must reinstall the sensor system image.

After you upgrade any IPS software on your sensor, you must restart the IDM to see the latest software features.

The IDM does not support any non-English characters, such as the German umlaut or any other special language characters. If you enter such characters as a part of an object name through IDM, they are turned into something unrecognizable and you will not be able to delete or edit the resulting object through IDM or the CLI. This is true for any string that is used by the CLI as an identifier, for example, names of time periods, inspect maps, server and URL lists, and interfaces.

When SensorApp is reconfigured, there is a short period when SensorApp is unable to respond to any queries. Wait a few minutes after reconfiguration is complete before querying SensorApp for additional information.

The IDM and IME launch MySDN from the last browser window you opened, which is the default setting for Windows. To change this default behavior, in Internet Explorer, choose Tools > Internet Options, and then click the Advanced tab. Scroll down and uncheck the Reuse windows for launching shortcuts check box.

Caveats


Note If you have an ASA 5512-X IPS SSP, ASA 5515-X IPS SSP, ASA 5525-X IPS SSP, ASA 5545-X IPS SSP, or ASA 5555-X IPS SSP and you inspect fragmented traffic, you may be affected by known issue CSCue51272. CSCue51272 results in the ASA show module command showing the IPS Data Plane Status to be Down. This issue was originally identified by known issue CSCuc74630, because the symptoms are similar. CSCuc74630 is resolved in 7.1(7); however, CSCue51272 is not. We plan is to resolve CSCue51272 in a follow-on patch, 7.1(7p1), and eventually in 7.1(8).
