TCP DDoS vulnerabilities and methods of mitigation TCP is vulnerable to several types of DDoS attacks, including: SYN flood SYN floods occur during the initial stage of a three-way handshake by sending TCP connection requests (SYN packets) to every port on a target machine faster than it can ...
TCP and UDP headers have a section for indicating port numbers. Network layer protocols — for instance, the Internet Protocol (IP)— are unaware of what port is in use in a given network connection. In a standard IP header, there is no place to indicate which port the data packet ...
Find out what your public IPv4 and IPv6 address is revealing about you! My IP address information shows your IP location; city, region, country, ISP and location on a map. Many proxy servers, VPNs, and Tor exit nodes give themselves away.

Telnet operates using TCP Port 23 and provides many systems with an unencrypted communications channel for text-based information. It's most common usecase is as an Operations and Management interface (O&AM) for network attached devices; where an administrator will use Telnet to connect via IPv4...
Port 25 is the default SMTP port to send and receive emails. It uses Transmission Control Protocol (TCP) to establish a connection between two computers. SMTP port 25 is a good channel to test your connection or troubleshoot email configuration issues. For example, suppose the server won’t ...
Previously, the SMB server in Windows mandated inbound connections to use the IANA-registered port TCP/445 while the SMB TCP client allowed only outbound connections to that same TCP port. Now, SMB over QUIC allows for SMB alternative ports where QUIC-mandated UDP/443 ports are available for ...
An SMB port is a network port commonly used for file sharing that is susceptible to an exploit known as EternalBlue exploit that resulted in WannaCry.
Like anonymous FTP, it works on port 21. FTP Secure (FTPS) Also known as FTP-SSL, this is an extension of the standard FTP, that upgrades the connection with the implicit use of Transport Layer Security (TLS) or Secure Socket Layer (SSL). The client is immediately expected to challenge...
其实说HTTP协议可靠协议并不是特别的准确,HTTP的可靠性一部分来自于HTTP协议自身,一部分来自于它所依赖的上层TCP协议。 TCP本身就是一个可靠的传输协议,它的可靠性其实就是来自于三次握手,通过客户端与服务器的沟通来确定是否建立连接,UDP就没这么麻烦,传过去就完事了,我管你收没收到。所以基于这样的因素,TCP就不...
