MACsec知らなかった。レイヤー2で強力な暗号化を提供するIEEE 802.1AE規格。フレームのEtherTypeとペイロードを暗号化。データ発信元の保証など。へー。ということはARP Spoofing対策にもなる?MACsecの解説としても有用記事だ
AWS Direct Connect 接続に MACsec セキュリティを追加する | Amazon Web Services
AWS Direct Connect は、MACsec セキュリティ(IEEE 802.1AE)をサポートし、ネットワークから AWS に到着するまでのデータを保護するための新しい選択肢を提供します。このリリースにより、Direct Connect は、10Gbps および 100Gbps のリンクに対して、ネイティブ、ニアラインレート、およびポイントツーポイントの暗号化を提供します。専用接続(Direct Connect のイーサネットポートが単一の顧客に専用化されている場合)で一部のロケーションで利用できる MACsec は、利用可能な最高速度で AWS への安全な接続が必要な場合に最適な選択肢です。

AWS Direct Connect extends MACsec functionality to supported Partner Interconnects
AWS Direct Connect now supports IEEE 802.1AE MAC Security Standard (MACsec) encryption on Partner-owned interconnects terminated on supported physical devices. Partners using supported devices can now encrypt the Layer 2 connection between their edge network device and the Direct Connect device https://aws.amazon.com/directconnect/locations/ where MACsec is supported. MACsec is designed to deliver native, near line-rate, point-to-point encryption at Layer 2 between AWS’ network device and the Partner’s edge device on the other end of that connection. Partners who enable the feature can now encrypt all customer traffic traversing the secured link. The https://web.archive.org/web/20210404164829/https://docs.aws.amazon.com/directconnect/latest/UserGuide/Welcome.html?sc_channel=ta&sc_campaign=dx100g&sc_geo=mult&sc_country=global&sc_outcome=pa&sc_medium=dx-docs provides instructions for how to set up MACsec on supported 10Gbps and 100Gbps interconnects. Partners can request MACsec-capable interconnects and manage the new feature through the https://web.archive.org/web/20210404164829/https://console.aws.amazon.com/directconnect/v2/home or supported APIs.

A lot of people have to be brow-beaten into adopting MACsec, 802.1x, and MFA. NSPM-12 ought to be codifying current practice rather than forcing USG agencies to pull their heads out of their rectums.

Mein Horror ist immer Wifi Access Point zwischen Drucker und Wanddose. Den sieht niemand und der exfiltriert dir alle druckjobs. Print on Demand hilft auch nicht.

Deshalb wäre ich interessiert wer hier schon 802.1x + MACSec an Druckern implementiert hat?

PKI für die Drucker?

This is sort of the predecessor of the 64x800 - bad picture but if you notice half of the ports have air vents up and down. They are the half 16 which do macsec.

This device is used at the edge of AWS premises (ie az to az) so that traffic only leaves encrypted.

AWS Direct Connect announces 100G expansion in Makati City, Philippines
Today, AWS announced the expansion of 10 Gbps and 100 Gbps dedicated connections with MACsec encryption capabilities at the existing https://aws.amazon.com/directconnect location in the ePLDT data center near Makati City, Philippines. You can now establish private, direct network access to all public AWS Regions (except those in China), AWS GovCloud Regions, and https://aws.amazon.com/about-aws/global-infrastructure/localzones/ from this location. The Direct Connect service enables you to establish a private, physical network connection between AWS and your data center, office, or colocation environment. These private connections can provide a more consistent network experience than those made over the public internet.  For more information on the over 146 Direct Connect locations worldwide, visit the https://aws.amazon.com/directconnect/locations/ section of the Direct Connect https://aws.amazon.com/directconnect.
