astsu

astsu 작동 방식 일반 포트 스캔 정의된 포트로 대상에 TCP Syn 패킷을 보냅니다. 포트가 열려 있으면 nmap 스캔을 사용하여 포트에서 실행 중인 서비스를 확인하고 발견된 모든 포트를 출력합니다. 네트워크 내 호스트 발견 라우터 IP를 기준으로 모든 가능한 IP를 매핑합니다. 그런 다음 각 IP에 ICMP 패킷을 보내고 응답을 기다립니다. 응답을 받으면 온라인 호스트의 IP를 배열에 저장하고, 모든 호스트를 확인한 후 온라인 상태인 모든 호스트를 출력합니다. OS 스캔 대상에 ICMP 패킷을 보내고 응답을 기다립니다...

A High-Throughput FPGA Architecture for Real-Time TCP-SYN Scan Detection

TCP-SYN port scanning often precedes cyber-attacks, and early detection of scanner fingerprints embedded in packet headers can provide timely intrusion alerts. Existing approaches are either too computationally expensive for line-rate operation or limited to offline analysis. This brief presents ...
