Axis products with AXIS OS 11 now support IEEE 802.1AE MACsec, significantly enhancing security in zero-trust networks

Enhanced data encryption with AXIS OS 11.8

With AXIS OS 11.8, MACsec is enabled by default (through EAP-TLS/Dynamic CAK mode). Data is encrypted at the Ethernet Layer 2 (data link) network level, safeguarding the integrity of data being transferred between Axis devices and MACsec-enabled Ethernet switches. Because it operates at layer 2, MACsec can encrypt and protect data that could not previously be encrypted such as NTP, DHCP for general device operation, and RTP/RTSP for video streaming. Even if a user is already implementing HTTPS or a different form of encryption at another layer, adding MACsec at layer 2 effectively double encrypts the data, ensuring that an attacker would need to intercept and decrypt both layers in order to see or steal critical information. This makes the attacker’s job considerably more difficult, significantly increasing protection against attacks including denial of service, intrusion, man-in-the-middle data insertion and eavesdropping.

Zero-touch integration pairs with zero-trust strategy

“Customers benefit from security features that are enabled by default and that do not require any pre-configuration,” says Andre Bastert, Global Product Manager of AXIS OS. “They lower installation complexity, and thereby, literally save time and money. These security features are great examples of zero-trust security that do not require more time from customers.  With the increase in the convergence of OT (operational technology) and IT (information technology), these standard security mechanisms are what IT professionals expect of smart IoT products, and we are meeting their needs as part of Axis’ long-term strategy to enable secure, zero-touch integration of Axis network products into zero-trust networks.”

Seamless onboarding and integration

The adoption of IEEE 802.1AE MACsec builds on Axis’ implementation of the IEEE 802.1AR Secure Device Identity (DevID) standard, together with IEEE 802.1X EAP-TLS network access control. Default support for the three IEEE standards on Axis devices enables automated device onboarding, authentication, and end-to-end encryption, providing IT professionals with standard mechanisms to efficiently and securely integrate Axis devices into a corporate network. 

MACsec allows for an exchange and verification of encryption keys between a MACsec-enabled device and switch. Data within each Ethernet frame is then encrypted and decrypted in real time using AES-GCM 128-bit, enabling fast and secure transfer of data. AXIS OS 11.8 supports the two standard IEEE 802.1AE security modes: dynamic CAK (EAP-TLS), which is automatic and enabled by default, and static CAK (pre-shared key) for manual configuration.

Secure onboarding of an Axis device can be done through IEEE 802.1X EAP-TLS port-based network access control, in combination with an Axis device’s support for IEEE 802.1AR. IEEE 802.1AR is part of the Axis Edge Vault cybersecurity platform and enables automatic authentication in an IEEE 802.1X network. Axis loads unique, IEEE 802.1AR-compliant Initial Device Identifiers (IDevIDs) into a tamper-protected hardware cryptographic computing module that is embedded in Axis IoT products at the time of manufacture, protecting the IDevIDs against probing. 

Seamless onboarding can be achieved with any network access control solution that supports the IEEE standards; for instance, with HPE Aruba Networking ClearPass Policy Manager, for which an integration guide is available.
