Cisco warns a critical patch is needed for a remote access firewall, VPN and router

Cisco is warning organizations with remote users that have deployed a particular Cisco wireless firewall, VPN and router to patch a critical vulnerability in each that could let attackers break into the network.The vulnerability, which has an impact rating of 9.8 out of 10 on the Common Vulnerability Scoring System lets a potential attacker send malicious HTTP requests to a targeted device. A successful exploit could let the attacker execute arbitrary code on the underlying operating system of the affected device as a high-privilege user, Cisco stated. More about edge networking How edge networking and IoT will reshape data centers Edge computing best practices How edge computing can help secure the IoT The vulnerability is in the web-based management interface of three products: Cisco’s RV110W Wireless-N VPN Firewall, RV130W Wireless-N Multifunction VPN Router and RV215W Wireless-N VPN Router. All three products are positioned as remote-access communications and security devices.To read this article in full, please click here

ICANN urges adopting DNSSEC now

Powerful malicious actors continue to be a substantial risk to key parts of the Internet and its Domain Name System security infrastructure, so much so that The Internet Corporation for Assigned Names and Numbers is calling for an intensified community effort to install stronger DNS security technology. Specifically ICANN is calling for full deployment of the Domain Name System Security Extensions (DNSSEC) across all unsecured domain names. DNS,often called the internet’s phonebook, is part of the global internet infrastructure that translates between common language domain names and IP addresses that computers need to access websites or send emails.  DNSSEC adds a layer of security on top of DNS.To read this article in full, please click here
