ADM Defender

ADM Defender provides preset and customizable firewall profiles. Intelligent security protection can proactively prevent suspicious IP addresses from connecting to your NAS. ADM can also monitor network transmission packets to intercept suspicious network activities. The new design makes it easier to enable the firewall and additional security protections. ADM Defender proactively prevents suspicious connections, which can help further reduce the risks of malware and attacks to further improve data security.


Overview:

Information about various security protection settings can be displayed here.


Trusted List:

IP addresses specified in the trust list have the highest priority in allowing connections and will override addresses found in automatic blacklist.


Intelligent Security Protection:

  • Auto Black List:
    The automatic blacklist blocks IP addresses that make too many unsuccessful attempts to log in within a set amount of time. Specific policies can be changed by administrators in Settings.
  • Risk Detection Greylist:
    When enabling risk IP detection, ADM will check the addresses of devices that attempt to connect to a NAS. IP addresses that are not in the automatic blacklist by the firewall and the trustlist are given a risk rating. By comparing addresses with the risk detection greylist stored on ADM, the AbuseIPDB online database, the existence of addresses already found in the ADM risk detection greylist, or addresses exceeding a specified risk value will be directly blocked, preventing login. The blocked IP will be directly added to the greylist.
    The period of time an IP address is blocked can be set in Settings. By default, a suspicious IP address will be permanently blocked. The minimum time an address can be blocked is seven days.
    Before using this feature, please first sign up for an account at AbuseIPDB and obtain an API key. Click here to view instructions. Individual accounts have a maximum checks or reports per day. To increase the number of checks and reports, a paid plan from AbuseIPDB is required.

Firewall:

Use the firewall to allow or deny IP addresses, entire ranges, and/or entire countries access to your NAS. ADM Defender provides Intranet only and location-restricted profiles that can be applied directly by default as well as the ability to add custom profile. Customized firewall profiles can be configured to protect all or specific network interfaces, ports and protocols.
To ensure continued access when denying all connections to your NAS, ensure that your device IP addresses have been added to the allow list, otherwise all devices will be locked out.


To define IP addresses by geolocation, the Geo IP Database app on App Central must be installed first.
