5.3 DDoS Attacks 5.3.1 Attack Trend In 2018, we observed 148,000 DDoS attacks (down 28.4% from 2017), which generated a total of 643,100 TB of attack traffic, about the same volume as observed in 2017. This trend suggests that while the number of DDoS attacks is lower, the size of the attack are growing. Large […]

Overview Today, VMware released five vulnerabilities for Harbor Container Registry, including two officially classified as critical vulnerabilities (CVE-2019-19025, CVE-2019-19023), and two high-risk vulnerabilities (CVE-2019-19029, CVE- 2019-19026), and a medium-risk vulnerability (CVE-2019-3990).

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 […]
