Snort是一个开源的网络入侵检测系统(NIDS),其源码提供了丰富的功能和灵活的配置选项,用于实时监控和分析网络流量,以识别潜在的安全威胁。它支持多种协议和平台,并具备高度可扩展性,广泛应用于网络安全领域。
Snort是一款开源的入侵检测系统(IDS),它基于GPL许可,以下是一个简单的Snort源代码示例,用于检测TCP连接中的异常行为:
#include <stdio.h> #include <stdlib.h> #include <string.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> int main(int argc, char *argv[]) { if (argc != 3) { printf("Usage: %s <ip> <port> ", argv[0]); exit(1); } const char *ip = argv[1]; int port = atoi(argv[2]); int sockfd = socket(AF_INET, SOCK_STREAM, 0); if (sockfd < 0) { perror("socket"); exit(1); } struct sockaddr_in server_addr; memset(&server_addr, 0, sizeof(server_addr)); server_addr.sin_family = AF_INET; server_addr.sin_port = htons(port); inet_pton(AF_INET, ip, &server_addr.sin_addr); if (connect(sockfd, (struct sockaddr *)&server_addr, sizeof(server_addr)) < 0) { perror("connect"); exit(1); } char buffer[1024]; ssize_t bytes_received = recv(sockfd, buffer, sizeof(buffer) 1, 0); if (bytes_received < 0) { perror("recv"); exit(1); } buffer[bytes_received] = '
