Nmap supports, among others, the following techniques: TCP connect (), TCP SYN (half open), ftp proxy (bounce attack), ICMP (ping sweep), FIN, ACK sweep, Xmas Tree, SYN sweep, UDP, and Null scans. You can also do OS detection via TCP/IP fingerprinting 4, decoy scanning, and fragmentation scanning.

This is commonly referred to as a Christmas Tree Packet and is intended to increase processing on in-path network devices and end hosts to the target.
Amid network transformations, security measures also had to evolve. With vital personal and business data being shared on computer networks every day, security has become paramount in light of increased network attacks. A network attack can be defined as any method, process, or means used to maliciously attempt to compromise network security. client dev tun proto tcp remote 192.168.0.28 1194 resolv-retry infinite nobind persist-key persist-tun ca OpenVPN+CA.crt cert UserCertificate.crt key UserCertificate.key cipher AES-256-CBC verb 5 I created the certificate authority and the server/user certificate : Then i had some firewall and NAT rules :
