Linux Network Namespaces 1. What are Linux Network Namespaces? A Network Namespace is a virtualization technology provided by Linux that allows the creation of multiple independent network environments, each with its own network interfaces, routing tables, iptables rules, etc. This is similar to network isolation in virtual machines or containers, but is more lightweight. Features … Read more

1. Definition of Asymmetric Encryption Algorithms An asymmetric encryption algorithm is a type of encryption technology that uses a pair of keys for encryption and decryption. Unlike symmetric encryption, asymmetric encryption uses two keys: a public key for encrypting data and a private key for decrypting it. Only the recipient who possesses the private key … Read more

Executive SummaryIn recent years, an increasing number of protocols capable of causing UDP reflection attacks have come to the forefront, such as CoAP[1], Ubiquiti[2], WS-Discovery[3], OpenVPN[4], and a certain DVR protocol[5]. These attack methods differ from the well-known reflection attack types like DNS, SSDP, NTP, and Memcached, posing certain challenges for DDoS attack protection. In … Read more
Variety is the spice of life. Change is the spice of life. 1. Introduction to HTTP and HTTPS HTTPS = HTTP + SSL Similarities In most cases, HTTP and HTTPS are the same because they both use the same underlying protocol. As an HTTP or HTTPS client—browser—establishes a connection to the web server on a … Read more
