Advanced system settings

Several features for advanced users are located on Administration > System Settings > Advanced.

Primary Tenant Access

By default, the primary tenant can access your Deep Security environment.

If the primary tenant enabled the "Primary Tenant Access" settings in your environment, however, you can prevent the primary tenant from accessing your Deep Security environment, or grant access for a limited amount of time.

Load Balancers

Agents are configured with a list of Deep Security Manager and Deep Security Relays. When multiple managers and relays are deployed without a load balancer, agents will automatically contact the managers and relays using a round robin sequence.

To better scale your network, you can put a load balancer in front of the managers or relays. When you configure the load balancer hostname and port numbers, it will override the IP address or hostname and port numbers currently used by the agents.

The script generator uses the address of the Deep Security Manager that you are connected to. This ensures that the scripts continue to function even if one of the Deep Security Manager nodes fails or is down for maintenance or upgrades.

Multi-tenant Mode

1. Select Enable Multi-Tenant Mode.
2. In the wizard that appears, enter your Multi-Tenant Activation Code and click Next.
3. Select the license mode, either:
   • Inherit Licensing from Primary Tenant: All tenants use the same licenses as the primary tenant.
   • Per Tenant Licensing: Tenants themselves enter a license when they log in for the first time.
4. Click Next.

Deep Security Manager Plug-ins

Plug-ins are modules, reports and other add-ons for the Deep Security Manager. Trend Micro occasionally produces new or additional versions of these which are distributed as self-installing packages.

SOAP Web Service API

Much of the Deep Security Manager's functionality can be controlled via SOAP-invoked Web services. The WSDL (Web Services Description Language) can be found at the URL displayed in the panel on the page. For assistance with Deep Security Manager's Web services API contact your support provider.

Status Monitoring API

The REST Status Monitoring API lets you query the Deep Security Manager (including individual Manager Nodes) for status information such as CPU and memory usage, number of queued jobs, total and Tenant-specific database size. For assistance with Deep Security Manager's REST Status Monitoring API contact your support provider.

Export

Export file character encoding: The character encoding used when you export data files from the Deep Security Manager. The encoding must support characters in your chosen language.

Exported Diagnostics Package Language: Your support provider may ask you generate and send them a Deep Security diagnostics package. This setting specifies the language the package will be in. The diagnostic package is generated on Administration > System Information.

Whois

Whois can be used to look up which domain name is associated with an IP address when you review logged intrusion prevention and firewall events. Enter the search URL using "[IP]" as a placeholder for the IP address to look up.
(For example, "http://reports.internic.net/cgi/whois?whois_nic=[IP]&type=nameserver".)

Licenses

Hide unlicensed Protection Modules for new Users determines whether unlicensed modules are hidden rather than simply grayed out for subsequently created Users. (This setting can be overridden on a per-user basis on Administration > User Management > Users > Properties).

Scan Cache Configurations

CPU Usage During Recommendation Scans

This setting controls the amount of CPU resources dedicated to performing Recommendation Scans. If you notice that CPU usage is reaching unreasonably high levels, try changing to a lower setting to remedy the situation. For other performance controls, see Administration > Manager Nodes > Properties > Performance Profiles.

Logo

You can replace the Deep Security logo that appears on the login page, at the top right of the Deep Security Manager GUI, and at the top of reports. Your replacement image must be in PNG format, be 320 px wide and 35 px high, and have a file size smaller than 1 MB. A template is available in the installfiles directory of the Deep Security Manager.

Click Import Logo to import your own logo, or click Reset Logo to reset the logo to its default image.

Manager AWS Identity

You can configure cross-account access. Select either:

• Use Manager Instance Role: The more secure option to configure cross-account access. Attach a policy with the sts:AssumeRole permission to the Deep Security Manager's instance role, then select this option. Does not appear if the Deep Security Manager does not have an instance role, or if you're using an Azure Marketplace or on-premise installation of Deep Security Manager.
• Use AWS Access Keys: Create the keys and attach a policy with the sts:AssumeRole permission before you select this option, and then type the Access Key and Secret Key. Does not appear if you're using an Azure Marketplace or on-premise installation of Deep Security Manager.

Application control

Each time you create an application control ruleset or change it, it must be distributed to all computers that use it. Shared rulesets are bigger than local rulesets. Shared rulesets are also often applied to many servers. If they all downloaded the ruleset directly from the manager at the same time, high load could cause slower performance.

Using Deep Security Relays can solve this problem.

• If you don't have multi-tenancy, go to Administration > System Settings > Advanced and then select Serve application control rulesets from relays.

  

• In multi-tenancy, the primary tenant (t0) can't access other tenants' (tN) configurations, so t0 relays don't have tN application control rulesets. (Other features like IPS don't have this consideration, because their rules come from Trend Micro, not a tenant.)

  Other tenants (Tn) must create their own relay group, then select Serve application control rulesets from relays.
