Encryption in c

RuleSet of traffic parameters and other conditions in a Rule Base (Security Policy) that cause specified actions to be taken for a communication session. Base. In some cases you may need to configure the Encryption Domain in a granular way. You can configure the VPN domain of a Security Gateway per community, which makes it safer and easier to control the VPN communities that are logically separated. Example 1 Security Gateway A (Partner A) is part of Community-1. Security Gateway B (Partner B) is part of Community-2. Security Gateway C (Corporate Branch) is part of both Communities 1 and 2. The network behind Security Gateway C - 10.2.2.0 is split into 2 networks using the 255.255.255.128 subnet mask. In this scenario, the administrator limits the access from Security Gateway A in community 1 to some of the resources behind Security Gateway C which is also part of community 1. To allow access to the required resources from Security Gateway A to resources protected by Security Gateway C, the administrator configures an Encryption Domain per the specific community so although Security Gateway C is a part of another community (Community 2) which is configured differently. The access is limited to the specific Encryption Domain: network 10.2.2.0/25. Configuring the Encryption Domain per Community Open the VPN community. Double click the center Security Gateway that participates in more than one VPN community (Security Gateway C in this scenario). The VPN domain configuration window opens. Select the option. Configure the Encryption Domain. In our example the encryption domain includes the network we allow partner B to access. Click . Example 2 Using the same setup, you can use the Encryption Domain per Community configuration to allow access between host 1 and host 2 in both directions. The configuration changes are applied to the Encryption Domain of Security Gateway-C per each relevant community, in this example Communities 1 and 2. Note - In previous versions to get this functionality the vpn_route.conf file was used. Configuration: Community Encryption Domain Install On Community-1 Network behind Security Gateway-C Host-2 Security Gateway-C Security Gateway-A Community-2 Network behind Security Gateway-C Host-1 Security Gateway-C Security Gateway-B Create a new host (Host-2 behind Security Gateway-B) to represent the Encryption Domain of Security Gateway-C to publish for Security Gateway-A. Create a new host (Host-1 behind Security Gateway-A) to represent the Encryption Domain of Security Gateway-C to publish for Security Gateway-B. Create a new Network group to include the current Encryption Domain of Security Gateway-C and the additional host (Host-2) for Community-1. Create a new Network group to include the current Encryption Domain of Security Gateway-C and the additional host (Host-1) for Community-2. For Community-1 change the Encryption Domain for Security Gateway-C, use the

And host 2 in both directions. The configuration changes are applied to the Encryption Domain of Security Gateway-C per each relevant community, in this example Communities 1 and 2. Note - In previous versions to get this functionality the vpn_route.conf file was used. Configuration: Community Encryption Domain Install On Community-1 Network behind Security Gateway-C Host-2 Security Gateway-C Security Gateway-A Community-2 Network behind Security Gateway-C Host-1 Security Gateway-C Security Gateway-B Create a new host (Host-2 behind Security Gateway-B) to represent the Encryption Domain of Security Gateway-C to publish for Security Gateway-A. Create a new host (Host-1 behind Security Gateway-A) to represent the Encryption Domain of Security Gateway-C to publish for Security Gateway-B. Create a new Network group to include the current Encryption Domain of Security Gateway-C and the additional host (Host-2) for Community-1. Create a new Network group to include the current Encryption Domain of Security Gateway-C and the additional host (Host-1) for Community-2. For Community-1 change the Encryption Domain for Security Gateway-C, use the new group created in step 3. For Community-2 change the Encryption Domain for Security Gateway-C, use the new group created in step 4. This type of configuration "tricks" the satellite gateways to think that the destination host is part of Security Gateway-C 's Encryption Domain. Therefore, the satellite gateways encrypt the packets that they send to the center Security Gateway. The center Security Gateway decrypts the packets, re-encrypts them, and then re-routes them to the other satellite gateways. Specific VPN Domain for Gateway Communities If a Security Gateway participates in more than one VPN Community, you can configure a different VPN Domain for the Security Gateway for each VPN Community in which it participates. In SmartConsole, you can configure a specific VPN Domain for a Security Gateway in the Security Gateway object or in the VPN

In this scenario, the administrator limits the access from Security Gateway A in Community 1 to some of the resources behind Security Gateway C, which is also part of Community 1. To allow access to the required resources from Security Gateway A to resources protected by Security Gateway- C, the administrator configures an Encryption Domain per the specific community. On Security Gateway-C, the administrator must configure two Encryption Domains: one for Community 1 and one for Community 2. Domains The access is limited to the specific Encryption Domain: network 10.2.2.0/25. Configuring the Encryption Domain per Community Open the VPN community. From the left tree, click . In the section, double-click the center Security Gateway that participates in more than one VPN community (Security Gateway- C in this scenario). The VPN domain configuration window opens. Select the option. Select the applicable Network or Group object (or create a new object). Configure the Encryption Domain. In the example, the encryption domain includes the network that we allow partner B to access. Click . Example 2 Using the same setup, you can use the Encryption Domain per Community configuration to allow access between host 1
