(Environment) (AWS)(EC2) - (1) VS CODE 환경 에서 SSH 로 접근

익숙한 환경인 VS CODE 환경을 활용 해서 AWS 에 연결 하는 방법을 기록해 두고자 합니다. 

  • VS CODE 환경 에서 SSH 로 접근 하기 
    • 조건
      • AWS 가입 여부/서비스 생성, 시작 여부 확인
    • 사용하고자 하는 서비스에 대한 인스턴스 생성  
      • ECS 의 경우 Ubuntu 운영 체제로 생성하기 를 권장 함 (사유: Linux 사용시.. pip, apt get 사용에 있어 번거로운 과정을 요구 하게 됨)
    • 인스턴스에 대한 접속 정보 확인
    • (예시1 : EC2)
      • 메뉴 : EC2 > 인스턴스 > 인스턴스 ID (클릭) -> 인스턴스 요약 정보
      • 확인 가능한 정보 : 세부 정보, 보안, 네트워킹, 스토리지, 상태 검사, 모니터링, 태그
      • 필수 정보 확보
      • VS Code : "/Users/gshs/.ssh/config" 에 접속 정보 작성/저장
      • Host (AWS-EC2)abpolice_s210106_e221240
        HostName ec2-3-(ㅁㅁㅁㅁㅁ)-76.compute-1.amazonaws.com
        User ec2-user
        IdentityFile ~/.ssh/AWS_abpolice_s210106_e221230.pem
        • Host : 구분 가능한 이름 ( 사용자 작명) 본인의 경우 아이디와 사용 기간 조합
        • Host Name : 접속하고자 하는 서비스 인스턴스에 대한 Public IP 또는 퍼블릭 IPv4 DNS
        • User : 인스턴스 연결 후, 확인 되는 사용자 이름 , 본인의 경우'ubuntu'
        • IdentityFile : 키페어 생성으로 얻게된 pem 파일의, 다운 받은 PC 내 파일 경로 
    • VS Code 연결 실패시 연결 정보를 테스트 할수 있는 방법
      • 콘솔에서 직접 ssh 사용하여 연결, 성공/실패 여부에 따라 연결 정보 오류 검증 가능

[MaritimeCyberTrend] Relationship and prospects between U.S. Chinese maritime operations and maritime cybersecurity

Image
U.S. Sanctions on Chinese Ships & Cybersecurity Compliance The U.S. Trade Representative (USTR)’s sanctions on Chinese shipping and shipbuilding are expected to heighten the importance of cybersecurity regulations in vessel operations. In particular, as the U.S. increasingly frames Chinese-built ships and shipping companies as cybersecurity risks, compliance with maritime cybersecurity standards will become a critical issue for global shipping stakeholders. The United States is increasingly likely to classify Chinese-built vessels as national security and cybersecurity threats, using this as a basis for additional regulations and sanctions. In particular, drawing from past sanctions on Huawei and ZTE, the U.S. may argue that ships built in Chinese shipyards and equipped with Chinese IT systems (navigation, communication, and monitoring equipment) pose risks to the digital maritime infrastructure of the U.S. and its allies. As a result, the U.S. Coast Guard (USCG) is expected to s...

🌐 When a Ship's GPS Is Hacked: The Gap in Global Maritime Cyber Regulations – Examining the Reality of Cyber Incidents and the Shortfalls in Compliance Frameworks As maritime logistics rapidly digitalizes, the 2025 cyber grounding of MSC Antonia marks a clear turning point—showing that the industry must move beyond technology alone and embrace practical cyber resilience in real-world operations. The maritime cyber market has reached a turning point where it must move beyond mere technical compliance; it now requires the integrated operation of real-time threat response capabilities during vessel operation, organizational-level cyber governance, and the practical cybersecurity competence of crew members to effectively bridge the gap between stagnant global regulations and rapidly evolving threats. 📌 1. The 2025 MSC Antonia Incident – A Ship Hacked Mid-Voyage In May 2025, the MSC Antonia, a container ship operated by one of the world’s largest shipping lines, ran aground near Jedda...

Comprehensive List of Shipboard Systems in Commercial Vessels

Image
  Comprehensive List of Shipboard Systems in Commercial Vessels Beyond the core navigation, power, safety, cargo, and crew welfare systems, modern commercial ships incorporate a wide range of specialized systems to optimize operations, improve efficiency, and comply with international maritime regulations. Below is a detailed breakdown of shipboard systems, including advanced and auxiliary systems often overlooked. 1. Navigation & Control Systems (Ensuring Safe and Efficient Maneuvering) 📌 Core systems responsible for vessel control, automation, and positioning. Integrated Bridge System (IBS) – Merges multiple navigation tools into a single console for improved efficiency. Voyage Data Recorder (VDR) – The "black box" that records navigational and operational data for accident investigation. Speed Log System – Measures ship speed over water or ground using Doppler sensors. Echo Sounder (Depth Finder) – Detects underwater terrain to prevent grounding. Rudd...
