Administrators can enable auditing of the SMB server and client for support of SMB signing and encryption. If a non-Microsoft client or server lacks support for SMB encryption or signing, it can be detected. When a non-Microsoft device or software states it supports SMB 3.1.1, but fails to...
During UDP communication, the client sends a request packet to the server, and the server returns a response packet to the client. No verification is needed throughout the communication. The UDP protocol is connectionless and lacks a source authentication mechanism. These features are exploited by ...
When the client in Beijing sends a request to retrieve resources fromwww.aliyundoc.com, a domain name resolution request is sent to the local DNS server (LDNS) to retrieve the IP address ofwww.aliyundoc.com. The LDNS checks whether the cache contains the IP address that corresponds towww...
As a result of this vulnerability, the creators of botnet malware have evolved and moved towards a new model that is less susceptible to disruption via a single or a few points of failure. The peer-to-peer botnet model To circumvent the vulnerabilities of the client/server model, botnets ...
A single HTTP request is computationally cheap to execute on the client side, but it can be expensive for the target server to respond to, as the server often loads multiple files and runs database queries in order to create a web page. Layer 7 attacks are difficult to defend against, ...
QUIC is a transport protocol designed to replace TCP and improve web performance. It uses UDP, and HTTP/3 is designed to take advantage of it. When using HTTP/3 over QUIC, it’s faster to establish connections, and congestion control feedback is available to help avoid problems. As mention...

All communication over the Internet is exchanged via ports. Every IP address contains two kinds of ports, UDP and TCP ports, and there are up to 65,535 of each for any given IP address. Services that rely on the Internet (like web browsers, web pages, and file transfer services) rely...
Remote Desktop client for Windows: A standalone MSI installer. When installed, the application name is Remote Desktop. Remote Desktop app for Windows: Comes from the Microsoft Store. When installed, the application name is Remote Desktop.
UDP header format UDP communication process 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...
