Port 443, used for securing HTTPS traffic, has gained a lot of importance in the modern digital era. Encryption is beneficial to secure all sensitive information like login details, passwords, bank account numbers, etc. When data is exchanged on a regular port like port 80, all the informatio...
This article explores what is an open port and closed port? Risks of open ports, port scanning and how to monitor. Learn more on attack surface reduction.
UDP is a stateless transmission protocol, which reduces TCP's handshake, acknowledgment, windowing, retransmission, and congestion control mechanisms. When sending data, the UDP client does not determine whether the host is reachable or whether the server is started. Similarly, the UDP client ca...
Port numbers. Each port is assigned a unique number, ranging from 0 to 65535, which identifies the type of service or application. For example, HTTP typically uses port 80, while HTTPS uses port 443. TCP and UDP protocols.Ports operate using either the transmission control protocol (TCP) or...

TFTP uses port 69 for requests. Subsequently, communication is established via individually assigned port numbers (between 1024 and 65535), which the TFTP server sends to the requesting client in the form of TIDs (Transfer Identifiers). Note Many operating systems have already implemented their ...

If the protocol types, source IP address ranges, and destination IP address ranges are the same, the rule that defines the smallest Layer 4 port number (TCP/UDP port number) range is processed. If the preceding ranges are all the same, the rule with the smallest ID is processed. ...
