After 20 years of prominence, distributed denial-of-service (DDoS) attacks may be causing more devastating effects than ever. The first DDoS attack occurred way back on July 22, 1999 when a network of 114 computers infected with a malicious script called Trin00 attacked a computer at the University of Minnesota, according to MIT Technology Review. The infect

The two programming languages, Java and Python, are affected by serious FTP Injection flaws that can be exploited by hackers to bypass any firewall. Attackers can trick Java and Python applications to execute rogue FTP commands that would open ports in firewalls The unpatched flaws reside in the way the two programming languages handle File Transfer Protocol

As we approach Thanksgiving in the U.S., the one thing I look forward to the most — aside from turkey and spending time with my family — is football. As I watch the games, the security geek in me can’t help but notice some parallels between football and network security, particularly firewalls and intrusion prevention. Network Security Playbook During

Firewalls are staples of network security, and for years, they’ve played a part in keeping networks safe by restricting both incoming and outgoing network traffic. Along with antivirus software, they are among the oldest and most widely used cybersecurity tools.But what role should firewalls play in 2016 and beyond? One thing is clear: even though they’ve ev

Full NGFW integration yields streamlined security and greater value from investmentsWe know that security, when done properly, can be a business enabler. But as IT teams build out their security capabilities, the lack of integrated solutions yields lower threat effectiveness and inevitably leads to an explosion of complexity and cost.When Cisco developed the
