Security Manager

Security Manager is a fully integrated Antivirus/Anti-Malware engine designed to provide comprehensive protection to Windows Servers and Workstations. More information on this feature can be found in the N-able N-central Online Help.

The security features of N-able N-central provide for flexible deployment and updating without posing undue load on the service provider or end user networks. This is achieved through a distributed update architecture. This architecture is outlined below, and consists of the N-able N-central server, Agents, Probes, and an N-able hosted update server.

Upgrades and Updates

Upgrades and updates to the Bitdefender software can be divided into three categories:

Product Upgrades (Major Releases)

  • The Agent will attempt to download the catalog file from sis.n-able.com every time that is specified in the Maintenance Windows usually every hour.

  • If an upgrade is available, the AV Defender Status service will transition to a Warning state to indicate that an upgrade is available.

  • AV Defender will download from the probe of and apply the upgrades as defined by the maintenance Window or when configured to do so from the All Devices View > Upgrade Monitoring Software. Re-starting devices is usually needed following a product upgrade and the AV Defender Status service will indicate that a restart is required and the Agent will initiate the restart once it is permitted by the Maintenance Window.

 

Product Updates (Hot Fixes)

  1. AV Defender checks the local Update Server for Updates.

  2. The Update Server checks upgrade.bitdefender.com for updates every half hour.

  3. Agents outside of the corporate network checks upgrade.bitdefender.com directly for Updates.

  4. AV Defender Status service will transition to a Warning state.

  5. The Update is downloaded from the Update Server or upgrade.bitdefender.com.

  6. AV Defender Updates are installed by the Maintenance Windows or manually.

Definition File Updates (Security Signatures)

More Information on Definition File Updates

Ensuring that your definition files are up to date is a critical aspect of managing AV Defender. Again, N-able N-central leverages a distributed architecture to make distribution of these files fast and efficient.

  • AV Defender Profiles in N-central allow the user to configure the update frequency as well as the failover behavior.

  • Local Update Servers check for updates from the Bitdefender Update Server (upgrade.bitdefender.com) on a specific schedule.

  • Definition File Updates are downloaded from the Update Server if available or directly from Bitdefender all using port 443.

  • If an update server is configured for a Customer or Site, then AV Defender will use the local update server. If no update servers are selected, the AV Defender Status service will transition to a Warning state.

  • If the Allow Failover to External Update Server property is enabled and Immediately is selected, AV Defender will obtain Definition file updates from upgrade.bitdefender.com.

  • If the Allow Failover to External Update Server property is enabled and After <x> Hours is selected, AV Defender will then try to obtain updates from local update servers after every configured interval period has ended. If it is unable to check for updates for the configured number of hours, it will obtain the next update directly from the Bitdefender update server using port 443.
