The AK-SM 800A offers secure system control and monitoring whilst including energy saving functions that contribute to continuous and autonomous energy savings for your stores.

Danfoss takes security seriously and as part of our continued improvements, new measures are being implemented. Please review below important security updates included in the latest AK-SM 800A software update that may impact your upgrade experience

System Manager AK-SM 800A software package v4.0x and above enhances your product's security features to meet internationally recognized regulations such as the NIS2 and CRA Directives. Also following the global standard IEC 62443-4-1 Standard regarding IT security by design principles

In compliance, Danfoss is now defaulting to a strong security posture on the System Manager Ak-SM 800A, via software package 4.0.x and above. This feature is called Session Control and when combined with HTTPS improves overall security of your product.

What is Session Control?

Sesson control in the AK-SM 800A is an authentication rules engine/module and is intended to improve the overall security posture of your system. Session control offers different configuration settings (Backward compatibility, Permissive and Strict). Depending on how these settings are configured, the remote interface will need to comply accordingly.

What is a remote Interface?

The term remote interface refers to StoreView Browser 5 (SvB5), StoreView Web (SvW), Alsense™ (Danfoss Digital services) and 3rd party XML1.0. SvB5, SvW and Alsense™ already support Session control. 3rd party XML1.0 users will need to update requests if Strict mode remains selected (see below).

What are these Session Control settings?
The important aspect to note is that immediately after installing System Manager AK-SM 800A software package 4.0.x and above, Strict mode is set by default. These settings can always be managed via the System Manager Configuration>Security menu (Supervisor permission level required).

After AK-SM 800A software package 4.0.x is installed, Strict mode is default, what does this mean?

• Your AK-SM 800A now requires secure Internet standard of HTTPS (encrypts all data in transit)
• In Strict mode, 3^rd Party XML communications to the AK-SM 800A cannot contain usernames/passwords and must provide the session token in the AKSM-auth header
• For AK-SM 800A systems that have 3^rd party XML interfaces, Danfoss has supporting documentation, please contact Danfoss Technical Support
• Depending on your method of upgrade a pop-up message will be presented, informing of Strict mode but also allowing fall back to Backward compatible
• Depending on your method of upgrade your remote browser session my be lost. In this event you may need to manually type https in front of your system managers IP / DNS name
• After the software installation you may revert back to (weaker configuration) by selecting ‘Backward Compatible’ mode – Danfoss recommends Strict mode.

Important installation notes for System Manager Release 4.0.x

Before upgrading to Release4.0, take a moment to review your current implementation. For instance: check how your AK-SM 800A network is configured, are any 3rd Party XML entities involved?

After installation of System Manager software package 4.0x the unit will reboot and will Immediately default to Strict enforce level.

If you are uncertain about your AK-SM800A's current configuration for web communications, we strongly recommend performing on-site update only or having personnel on-site or contact Danfoss Technical support for further guidance

If your AK-SM 800A application is already configured for HTTPS, the remote update will not require any additional manual steps apart from confirming Strict mode.

If your AK-SM 800A application is configured for HTTP, there will be a workaround to support a remote update dependent on network setting (detailed guidelines will follow), but in case of any doubt an on-site update is always recommended.
