Network and Security Manager 2010.3 Release Notes

Version Summary

Juniper Networks Network and Security Manager (NSM) is a software application that

centralizes control and management of your Juniper Networks devices. With NSM, Juniper

Networks delivers integrated, policy-based security and network management for all

security devices and other Juniper Networks devices in your networks. NSM uses the

technology developed for Juniper Networks ScreenOS to enable and simplify management

support for previous and current versions of ScreenOS and now for Junos operating

system (Junos OS). By integrating management of all Juniper Networks devices, NSM

enhances the overall security and manageability of the Internet gateway.

New Features

The new feature in this release of NSM is support for configuring NAT on devices that

run on the Junos OS.

New or Changed Information

The following provides the new or changed information for this release:

•NSM supports management of SRX Series devices in packet and mixed mode.

•The wireless encryption configuration field, Static WEP (config > wlan > access point

> radio > virtual access point > security) has been renamed to Wireless Encryption.

•The Comment column of the firewall policy has been moved from the last position to

the third position from the last.

Before You Install NSM

Solaris Locales

Before installing NSM on a Solaris server, you must install a specific set of locales, and

make appropriate edits to the /etc/default/init file. For more information, see the Network

and Security Manager Installation Guide.

Upgrade Considerations

This section contains information about upgrading NSM and deprecated operating

systems.

Upgrading NSM

You can upgrade to NSM 2010.3 from the following versions:

•2008.2RX

•2009.1RX

•2010.1

•2010.2

Version Summary

NSM 2010.3 supports:

•3000 low-end devices with 10 user connections

•300 high-end devices with 25 user connections

Deprecated Operating System

NSM no longer supports ScreenOS version 4.X. You must upgrade your devices to

ScreenOS version 5.0 or later. NSM no longer supports Junos OS Release 9.2 or lower.

Limitations

The following items are known limitations in this version of NSM:

•NSM does not support Junos OS downgrades. However, if you need to downgrade a

device, follow these steps:

1. From the device, use the CLI command to downgrade the image. For example:

root> request system software add <package-name> reboot

2. After the downgrade, from NSM, delete the device and then add it again.

•For Junos OS J Series and EX Series devices—NSM Configuration Editor cannot

completely validate the configuration that an NSM user has created before sending it

to the device. The device validates the configuration when the configuration is pushed

to the device as part of the Update Device job and may return validation errors to NSM.

•For SSL VPN SA and Infranet Controllers—Secure Virtual Workspace (SVW) settings

on the SA device cannot be managed with NSM.

•For EX Series switches—EX Series switches running Junos OS do not support snapshots.

Therefore, users should not select the “Backup the current filesystem(s) on the device”

check box in the final page of the Install Device Software wizard.

Important SSL VPN and Infranet Controller Instructions

This section contains setup instructions and template usage guidelines for SSL VPN SA

(SA) and Infranet Controller (IC) devices.

NSM Server

•There is no limit to the number of devices that can be simultaneously updated in NSM,

provided the configuration size on each device being updated is less than 5 MB. NSM

can execute updates in parallel across a maximum of eight devices while the remaining

update jobs are queued up.

•If the software version of SA/IC configurations exceeds 5 MB, we recommend a

maximum of four devices per job for an appropriately sized Linux or Solaris server

running NSM.

Network and Security Manager 2010.3 Release Notes

•Due to hardware limitations on NSMXpress, the recommended limit is two devices per

job for SA/ICs running configurations more than 5 MB.

•The following files on the NSM software server must be edited as described below (no

changes are needed for NSMXpress):

•In /usr/netscreen/GuiSvr/bin/.guiSvrDirectiveHandler, change Xmx10248000000

to Xmx2048000000:

$LIB_DIR/jre/bin/java -DNSROOT=$NSROOT

-DgproGDM=$DEST_DIR -DNSDIR=$DEST_DIR/var/be

-DSTART_PATH=$DEST_DIR -DBE_CFG=${CFG_FILE}

-DLOG4J_CFG=${LOG4J_CFG_FILE} -XX:PermSize=64M

-XX:MaxPermSize=64M -Xms128000000 - Xmx2048000000

com.netscreen.devicecomm.GUIDirectiveManager -version -repo ${REPO_DEST_DIR}

-conf ${SVC_CFG_FILE}

•In /usr/netscreen/GuiSvr/var/xdb/data/DB_CONFIG, change the set_cachesize

parameter from 0 256000000 1 to 0 1024000000 4.

•Set the shared memory to a minimum of 1 GB (kernel.shmmax = 1073741824):

•In /etc/sysctl.conf, for Linux systems

•In /etc/system, for Solarix systems

•In /usr/netscreen/GuiSvr/var/xdb/specs/jax.spec, change Xmx512 to Xmx1024m:

:jvm-options (

: ("-DEMBEDDED_JVM=true")

: ("-Xms128m")

: ("-Xmx1024m")

•In /usr/netscreen/DevSvr/bin/.devSvrDirectiveHandler, change Xmx1024000000

to Xmx2048000000:

$LIB_DIR/jre/bin/java -DNSROOT=$NSROOT -DgproDDM=$DEST_DIR

-DNSDIR=$DEST_DIR/var/be -DSTART_PATH=$DEST_DIR

-DBE_CFG=${CFG_FILE} -DLOG4J_CFG=${LOG4J_CFG_FILE}

-XX:PermSize=64M -XX:MaxPermSize=64M -Xms128000000 - Xmx2048000000

com.netscreen.devicecomm.DeviceDirectiveManager -version -repo ${REPO_DEST_DIR}

-conf ${SVC_CFG_FILE}

The servers must be restarted after you change these parameters.

Important SSL VPN and Infranet Controller Instructions

Setting Up NSM to Work with Infranet Controller and Infranet Enforcer

A ScreenOS firewall that is managed by NSM can also be configured as an Infranet

Enforcer in a UAC solution. To prevent conflicts between NSM and the Infranet Controller,

configure these firewall devices:

1. On the Infranet Controller, create the Infranet Enforcer instances:

a. On the Infranet Controller, select UAC > Infranet Enforcer > Connection.

b. Click New Enforcer.

c. Enter the information requested in the display.

d. Enter a password for the NACN password. You will use it again while setting up

the Infranet Enforcer. If you are setting up a cluster instead of a single box, enter

all the serial numbers in the cluster, one per line.

e. Click Save Changes.

f. Repeat Step 1b through Step 1e until all of your Infranet Enforcers have been entered.

2. If you do not have one already, create a CA certificate for each Infranet Enforcer:

a. Create a certificate signing request (CSR) for an Infranet Controller server certificate,

and use the CA certificate to sign the server certificate.

b. Import the server certificate into the Infranet Controller.

c. Import the CA certificate into the Infranet Enforcer.

3. On each Infranet Enforcer, create the Infranet Controller instance:

a. On the Infranet Enforcer, select Configuration > Infranet Auth > Controllers.

b. Click New.

c. Enter the parameters as prompted. The password in the second section must be

the NACN password you entered in Step 1.d.

d. Click OK.

e. Repeat Step 3b through Step 3d for all of the Infranet Enforcers.

f. On the Infranet Controller, select UAC > Infranet Enforcer > Connection and

check that all the Infranet Enforcers have been added.

4. On NSM, delete the Infranet Enforcer firewalls from the global domain:

a. In the global domain, select Device Manager > Devices to list all the devices.

b. Right-click each Infranet Enforcer firewall device and select Delete from the list.

5. On NSM, delete the $infranet instances from the Object Manager:

a. Select Object Manager > Authentication Servers.

Network and Security Manager 2010.3 Release Notes

b. Right-click each $infranet_n object and select Delete from the list.

c. Select VPN Manager > VPNs, and check that you do not have any $infranet objects

under VPN Manager. These objects are usually deleted automatically when you

remove the firewall.

6. Create a new subdomain for the Infranet Enforcers:

a. Select Tools > Manage Administrators and Domains.

b. Select the Subdomains tab.

c. Click the Add icon.

d. In the New Subdomain dialog box, enter an appropriate name for the subdomain

so you know what it will be used for, and then click OK.

e. From the drop-down list at the top left side, select your new domain. The new

domain is empty, but it can use objects from the global domain. If you do not

remove the $infranet instances from the main domain, you risk having duplicate

$infranet names. In addition, add a Single Infranet Enforcer or Infranet Enforcer

Cluster.

f. Repeat Step 5 and Step 6 for every Infranet Enforcer or Infranet Enforcer Cluster

you need to add to NSM. When finished, you should see $infranet instead of

$infranet_# in each of the domains except global.

7. In NSM, add the Infranet Enforcer objects to the new domain:

a. Select Device Manager > Devices.

b. Click the Add icon, and then select Device to start the Add Device Wizard.

c. In the New Device window, provide a name for the device, a color for its icon in

NSM, and check Device is Reachable.

d. Follow the instructions in the wizard to add and import the device.

e. Repeat Step 7b through 7d for each Infranet Enforcer device.

You must reimport the configuration each time you use an Infranet Enforcer. Otherwise,

a NACN password mismatch is possible because the Infranet Controller dynamically

changes this password periodically. It is also good practice to do a “Summarize Delta

Config” and ensure that no $infra policies are present. If there are, the Infranet

Controller has changed something on the Infranet Enforcer since you last imported

the device configuration.

NOTE: If you choose not to reimport the configuration, be sure to update the

Infranet Controller and Infranet Enforcer at the same time.

Important SSL VPN and Infranet Controller Instructions

Usage Guidelines for Applying NSM Templates to SA and IC Clusters

SA/IC cluster configuration data is composed of Cluster Global (CG), Node-Specific

(NS), and Node-Local (NL) data, which are abstracted in NSM as cluster objects and

cluster member objects. The cluster object contains only CG data, while the cluster

member object contains NS and NL data. Template promotion and application to clusters

should be compliant with the cluster abstraction.

Recommended

•Templates that are applied to cluster objects should only include CG data. Templates

that are applied to cluster member objects should only include NS/NL data. These

guidelines apply to templates that are created from scratch or through promotion.

•To replicate the configuration from one cluster (source) to another cluster (target)

through templates, promote the configuration from the source cluster object to a

cluster template, and then apply that template to the target cluster object.

•To replicate the configuration from one cluster member (source) to another cluster

member (target), promote the configuration from the source cluster member object

to a member template, and then apply that template to the target cluster member

object.

Not Recommended

•Do not apply any template that contains NS/NL data to a cluster object. Application

of a template that contains NS/NL data can result in unexpected UI behavior and

update results (such as, NS/NL data from the template being ignored or NS/NL data

in cluster objects is invisible).

•Do not apply any template promoted from a cluster object or a standalone device to

a cluster member object. Node-specific settings in the template appear in the member

object but do not appear in the delta configuration. As a result, these settings appear

in the template but are not pushed to the back-end cluster node.

The following list shows the NS and NL configuration settings. All other settings are CG.

Best Practices

This section contains information about recommended practices when using NSM.

Maintaining the NSM GUI Server

For optimal NSM server performance, follow these maintenance procedures every few

months.

On the NSM GUI client:

•Delete old entries from the Job Manager in each domain.

•Purge old database versions using Tool > Database Versions.

If the size of the NSM database in /usr/netscreen/GuiSvr/var/xdb continues to increase

considerably despite the recommended practices, you can manually remove all domain

versions using the procedure documented in KB11731. For details, see

http://kb.juniper.net/KB11731.

Creating a Self-Signed TLS Certificate Between the NSM Client and the NSM Server

A self-signed certificate is a certificate that has not been signed by a third party, such as,

a well-known Certificate Authority (CA).

To create a self-signed certificate between an NSM server and an NSM client:

1. Download the file CreateCerts.zip from

http://kb.juniper.net/library/CUSTOMERSERVICE/GLOBAL_JTAC/BK14949/C

reateCerts.zip

2. Copy the file to the NSM server and unzip it.

#unzip createCerts.zip

Best Practices

3. Edit the file createCerts.sh and modify the section Default certificate generation

fields to update your current installation and the corresponding contact information

of your organization.

0.organizationName_default - <Name of Customer’s

Organization>stateOrProvinceName_default - <State>localityName_default -

<City>countryName_default - <Country>emailAddress_default - user@example.com

4. Run the shell script #sh Createcerts.sh

NOTE: The script produces a certificate with a timestamp that is nearly

10 years beyond the current date.

The following is an example of the output when the script is executed:

root@nsm/]# sh createCerts.sh

Enter NSM installation path[/usr/netscreen]>
