VPC 트래픽 미러링 – 네트워크 트래픽 캡처 및 검사 기능 출시 (서울 리전 포함)

VPC 트래픽 미러링 – 네트워크 트래픽 캡처 및 검사 기능 출시 (서울 리전 포함) 복잡한 서비스 네트워크를 운영하는 것은 쉬운 일이 아닙니다. 네트워크 침입, 손상된 인스턴스 또는 기타 다른 예외를 나타낼 수 있는 비정상적인 트래픽 패턴이나 콘텐츠를 항상 주의 깊게 관찰해야 합니다. 이를 위해 VPC 트래픽 미러링(Traffic Mirroring) 기능을 신규 출시했습니다. 이 기능은 기존  VPC와 함께 사용하여 대규모 네트워크 트래픽을 캡처하고 검사할 수 있습니다. 이 기능을 통해 다음을 수행할 수 있습니다. 네트워크 및 보안 이상 감지 – VPC의 모든 워크로드에서 관심 트래픽을 추출하여 원하는 감지 도구로 라우팅할 수 있습니다. 따라서 기존의 로그 기반 도구를 사용할 때보다 더 빠르게 공격을 감지하고 대응할 수 있습니다. 운영 통찰력 확보 – VPC 트래픽 미러링을 사용하여 보다 정확한 정보를 기반으로 보안 결정을 내리는 데 필요한 네트워크 가시성 및 제어 기능을 활용할 수 있습니다. 규정 준수 및 보안 제어 구현 – 모니터링, 로깅 등을 요구하는 규제 [ more… ]

Introducing tracking prevention, now available in Microsoft Edge preview builds

2019-06-28 KENNETH 0

Introducing tracking prevention, now available in Microsoft Edge preview builds Today, we’re releasing an experimental preview of tracking prevention for Microsoft Edge. We initially demoed this feature at Build 2019 as one of the concepts we’re exploring to offer greater transparency and control over your online data. Microsoft Edge Insiders can now try out tracking prevention by enabling the experimental flag on Microsoft Edge preview builds starting with version 77.0.203.0 (today’s Canary channel release). (Note: Today’s Canary release is not currently available for macOS due to a build issue. Tracking prevention will be available in the next update to the Canary channel on macOS.) Tracking prevention is designed to protect you from being tracked by websites that you aren’t accessing directly. Whenever a website is visited, trackers from other sites may save information in the browser using cookies and other storage [ more… ]
