2018 Cyberthreat Defense Report: Where IT Security Is Going

What keeps you awake at night? We asked IT security professionals the same question and found that these issues are top of mind: malware and spear phishing, securing mobile devices, employee security awareness and new technologies that detect threats capable of bypassing traditional signature-bas...

New DDoS Reflection-Attack Variant

This is worrisome: DDoS vandals have long intensified their attacks by sending a small number of specially designed data packets to publicly available services. The services then unwittingly respond by sending a much larger number of unwanted packets to a target. The best known vectors for these...
