An attacker doesn’t need an IoT botnet or massive resources for a denial of service attack to knock large servers offline; researchers warned that all it takes is one laptop for a “ BlackNurse ” attack to bring vulnerable Cisco, SonicWall, Palo Alto and Zyxel firewalls to their knees. MORE
New and innovative security tools seem to be emerging all the time, but the frontline defense for just about every network in operation today remains the trusty firewall. They aren’t perfect, but if configured correctly and working as intended, firewalls can do a solid job of blocking threats from entering a network, while restricting unauthorized traffic from leaving. The problem network administrators face is that as their networks grow, so do the number of firewalls. MORE

While always an integral part of a company’s security procedures, firewalls are becoming even more important as more companies move to the cloud and software defined networks. A firewall is a network security system that controls and monitors incoming and outgoing network traffic, based on preset security parameters. Firewalls create a barrier between a secure internal network and a potentially less-secure outside network. MORE

SAN FRANCISCO -- In some ways, Google is like every other large enterprise. It had the typical defensive security posture based on the concept that the enterprise is your castle and security involves building moats and walls to protect the perimeter.

And employees complained about having to go through a sometimes slow, unreliable VPN. MORE
