FBI Warning: New DDoS Reflection Attacks Are Coming, Are You Ready?
agosto 7, 2020
According to ZDNet’s reports, FBI released a warning last week that some new network protocols were used by criminals to launch large-scale DDoS attacks. Three protocols and one Web applications were found as DDoS attack vectors, including CoAP, WS-DD, ARMS and Web-based Jenkins.
(mais…)SDN-based Intelligent DDoS Cleaning System
dezembro 16, 2019
Traditional DDoS protection solutions are designed to address flexibility, scheduling, and value addition requirements. However, the advent of the software-defined networking (SDN) technology, especially its combination with network virtualization, provides a new way to deploy security devices. NSFOCUS’s SDN-based intelligent cleaning system discussed here can intelligently detect DDoS attacks and work out an optimal cleaning policy before selecting the most appropriate cleaning resources in real time, thus implementing intelligent traffic cleaning on demand to effectively protect users from DDoS attacks.

DDoS to Loom Large in the 5G Era
julho 9, 2019
Today, 5G is around the corner and, in the foreseeable future, it will definitely bring more convenience to our lives. Higher rates of mobile terminals, more devices connected to the Internet of Things (IoT), more convenient remote services… All these will lead us to a brand new era of the Internet of Everything (IoE). With constant breakthroughs in technological innovation, cybersecurity should also move at the same rate. (mais…)

Traceback of a DDoS Attack
janeiro 1, 2018
An abnormal increase in the CPU usage of a telecom carrier’s 4G firewall substantially slowed down the access from some iPhone users to the Apple website. We suspected that the carrier was hit by a DDoS attack. With the visualized traceback function of NSFOCUS Big Data Security Analytics (BSA), we made a drill-down analysis of […]

Flying at 40,000 feet above the ground always gives one a sense of clarity. Looking down on the world from such a height can make a person feel somewhat insignificant. However, my trip today is very noteworthy. I will be landing in Las Vegas in a few hours and the next four days will be filled with excitement, entertainment, and education. I am not going to Vegas for the adult playground activities like many of my fellow passengers. I am going there to attend the most exciting event of my career; the 2016 Sales Kickoff for a widely-unknown company in the U.S. called NSFOCUS IB. (mais…)
Anatomy of an attack: network bandwidth exhaustion
janeiro 5, 2016
Track: Technical
Author: Vann Abernethy, Field CTO, NSFOCUS
DDoS attacks come in three basic flavors: network-layer, application-layer and a hybrid of the two. This is a somewhat simplistic view but when you look at the strategy for taking someone down via DDoS, the two primary vehicles are either exhaustion of available network bandwidth or the overwhelming of back-end processing power (which can be directed either at the server system itself or the applications residing on them). The most efficient approach to take down a target will depend on the target itself. This is why it is important for every company to consider all of the assets that could become targets when designing anti-DDoS protection. (mais…)
