Overview (computer editor)
The computer editor Overview page has the following tabbed sections:
Hostname: Appears in the Name column on the Computers page. The name must be either the IP address of the computer or the hostname of the computer. Either a fully qualified hostname or a relative hostname can be used if a hostname is used instead of an IP address. You have to specify a hostname that can be resolved or a valid IP address that the Deep Security Manager can access. This is because the communication between the Deep Security Manager and the agent computers are based on the hostname. For relay-enabled agents, all of the computers within the relay group should be able to reach the specified IP address or hostname. If the Deep Security Manager cannot access the target computer the communication direction should be set to Agent/Appliance Initiated (Settings > Computer).
- Display Name: Appears in the Display Name column and in brackets next to the Hostname value.
- Description: a description of the computer.
- Platform: Details of the computer's OS will appear here.
- Group: The computer group to which the computer belongs appears in the list. You can reassign the computer to any other existing computer group.
- Policy: The policy (if any) that has been assigned to this computer.
Keep in mind that if you unassign a policy from a computer, rules may still be in effect on the computer if they were assigned independently of the policy.
- Asset Importance: Deep Security Manager uses a ranking system to quantify the importance of security events. Rules are assigned a severity level (high, medium, low, etc.), and assets (computers) are assigned an "asset importance" level. These levels have numerical values. When a rule is triggered on a computer the asset importance value and the severity level value are multiplied together. This produces a score which is used to sort events by importance. (Event ranking can be seen in the Events pages.) Use this Asset Importance list to assign an asset importance level to this computer. (To edit the numerical values associated with severity and importance levels, go to Administration > System Settings > Ranking.)
- Download Security Updates From: Use the dropdown list to select which relay group the agent/appliance on this computer will download security updates from. (not displayed if agent is acting as a relay.)
The Status area displays the latest available information about the computer and the protection modules in effect on it. Whether the computer is protected by an agent or an appliance (or both in the case of combined mode) is displayed in the top row.
- When the computer is unmanaged the status represents the state of the agent/appliance with respect to activation. The status will display either "Discovered" or "New" followed by the agent/appliance state in brackets ("No Agent/Appliance", "Unknown", "Reactivation Required", "Activation Required", or "Deactivation Required").
- When the computer is managed and no computer errors are present, the status will display "Managed" followed by the state of the agent/appliance in brackets ("Online" or "Offline").
- When the computer is managed and the agent/appliance is in the process of performing an action (e.g. "Integrity Scan in Progress", "Upgrading Agent (Install Program Sent)", etc.) the task status will be displayed.
- When there are errors on the computer (e.g., "Offline", "Update Failed", etc.) the status will display the error. When more than one error is present, the status will display "Multiple Errors" and each error will be listed beneath.
Protection module status
The software that implements Deep Security 9.5 or later protection modules is installed deployed to agents on an as-needed basis. Only core functionality is included when an agent is first installed.
The Status area provides information about the state of the Deep Security modules. The status reflects the state of a module on the agent as well as its configuration in Deep Security Manager. A status of "On" indicates that the module is configured in Deep Security Manager and is installed and operating on the Deep Security Agent.
A green status light is displayed for a module when it is "On" and working. In addition, modules that allow individual rule assignment must have at least one rule assigned before they will display a green light.
- Anti-Malware: Whether anti-malware protection is on or off and whether it is configured for real-time or on-demand scans.
- Web Reputation: Whether web reputation is on or off.
- Firewall: Whether the firewall is on or off and how many rules are in effect.
- Intrusion Prevention: Whether intrusion prevention is on or off and how many rules are in effect.
- Integrity Monitoring: Whether integrity monitoring is on or off and how many rules are in effect.
- Log Inspection: Whether log inspection is on or off and how many rules are in effect.
- Scanner (SAP): Status of the Deep Security Scanner SAP feature.
- Online: Indicates whether the manager can currently communicate with the agent/appliance.
- Last Communication: The last time the manager successfully communicated with the agent/appliance on this computer.
- Check Status: This button allows you to force the manager to perform an immediate heartbeat operation to check the status of the agent/appliance. Check Status will not perform a security update of the agent/appliance. When manager to agent/appliance communications is set to "Agent/Appliance Initiated" the Check Status button is disabled. Checking status will not update the logs for this computer. To update the logs for this computer, go to the Actions tab.
- Clear Warnings/Errors: Dismisses any alerts or errors on this computer.
- ESXi server: If the computer is a virtual machine protected by a virtual appliance, the hosting ESXi server is displayed.
- Appliance: If the computer is a virtual machine protected by a virtual appliance, the protecting appliance is displayed.
- ESXi Version: If the computer is an ESXi server, the ESXi version number is displayed.
- Filter Driver version: If the computer is an ESXi server, the filter driver version number is displayed. If you are using DSVA 9.6 or later with ESXi 6.0 or later, "N/A" will be displayed because no filter driver is in use.
- Guests: If the computer is an ESXi server, the virtual appliance and guests are displayed.
- Appliance Version: If the computer is a virtual appliance, the appliance version number is displayed.
- Protected Guests On: If the computer is a virtual appliance, the IP of the ESXi server and the protected guest are displayed.
VMware virtual machine summary
This section displays a summary of hardware and software configuration information about the virtual machine on which the agent/appliance is running (VMware virtual machines only).
Alert when TPM monitoring detects changes to ESXi hypervisor configuration: The Trusted Platform Module (TPM) is a hardware-based encryption module attached to a VMware ESXi. It monitors the boot sequence of an ESXi and generates an encrypted signature. Changes to the ESXi boot sequence could represent corruption of the stored image, tampering, or unexpected or unauthorized updates or other types of changes.
A newly installed Deep Security agent/appliance needs to be "activated" by the Deep Security Manager before policies, rules, requests for event logs, etc. can be sent to it. The activation procedure includes the exchange of SSL keys which uniquely identify a manager (or one of its nodes) and an agent
An unactivated agent/appliance can be activated by any Deep Security Manager.
Agents/Appliances can only be deactivated locally on the computer or from the Deep Security Manager which activated it. If an agent/appliance is already activated, the button in this area will read Reactivate rather than Activate. Reactivation has the same effect as activation. A reactivation will reset the agent/appliance to the state it was in after first being installed and initiate the exchange of a new set of SSL keys.
When you change the configuration of an agent/appliance on a computer using the Deep Security Manager (apply a new intrusion prevention rule, change logging settings, etc.) the Deep Security Manager has to send the new information to the agent/appliance. This is a "Send Policy" instruction. Policy updates usually happen immediately but you can force an update by clicking the Send Policy button.
This displays the version of the agent/appliance currently running on the computer. If a newer version of the agent/appliance is available for the computer's platform you can click the Upgrade Agent or Upgrade Appliance button to remotely upgrade the agent/appliance from the Deep Security Manager. You can configure the Deep Security Manager to trigger an alert if new versions of the agent/appliance software running on any of your computers by going to the Administration > System Settings > Updates tab.
Versions 9.5 and later of the Windows and Linux Agents can be configured to act as Deep Security relays. Relays distribute security and software updates throughout your network. Click Enable Relay to enable this functionality on the agent. Once an agent has relay functionality enabled, it will retrieve the latest security and software updates and distribute them according to your existing updates settings. For more information about relays, see About relay-enabled agents.
The Create Diagnostic Package button creates a snapshot of the state of the agent/appliance on the computer. Your support provider may request this for troubleshooting purposes.
If you have lost communication with the computer, a diagnostics package can be created locally. For more information, see Create a diagnostic package.
TPM (ESXi hypervisors only)
A Trusted Platform Module (TPM) is a type of chip that is used for hardware authentication. VMware uses the TPM with its ESXi hypervisors. During the boot sequence, an ESXi writes a SHA-1 hash of each hypervisor component to a set of registers as it loads. An unexpected change in these values from one boot sequence to the next can indicate a possible security issue worth investigating. Deep Security can monitor the TPM on an ESXi after every boot and raise an Alert if it detects any changes. If you select the option to enable TPM monitoring on an ESXi which doesn't support it, the option will be automatically disabled.
The minimum requirements for TPM monitoring are
- Deep Security Manager 9+
- vCenter 5.1+
- ESXi 5.1+
- TPM/TXT installed and enabled on the ESXi (consult your VMware documentation for details)
- The Deep Security Integrity Monitoring Module must be properly licensed.
