Cisco sounds warning on 3 critical security patches for DNA Center
Cisco issued three “critical” security warnings for its DNA Center users – two having a Common Vulnerability Scoring System rating of 9.8 out of 10.The two worst problems involve Cisco Data Center Network Manager (DCNM). Cisco DNA Center controls access through policies using Software-Defined Access, automatically provision through Cisco DNA Automation, virtualize devices through Cisco Network Functions Virtualization (NFV), and lower security risks through segmentation and Encrypted Traffic Analysis. More about SD-WAN How to buy SD-WAN technology: Key questions to consider when selecting a supplier How to pick an off-site data-backup method SD-Branch: What it is and why you’ll need it What are the options for security SD-WAN? In one advisory Cisco said a vulnerability in the web-based management interface of DCNM could let an attacker obtain a valid session cookie without knowing the administrative user password by sending a specially crafted HTTP request to a specific web servlet that is available on affected devices. The vulnerability is due to improper session management on affected DCNM software.To read this article in full, please click here

Oracle does-in Dyn, resets DNS services to cloud
Some may call it a normal, even boring course of vendor business operations but others find it a pain the rump or worse.That about sums up the reaction to news this week that Oracle will end its Dyn Domain Name System enterprise services by 2020 and try to get customers to move to DNS services provided through Oracle Cloud. More about DNS: DNS in the cloud: Why and why not DNS over HTTPS seeks to make internet use more private How to protect your infrastructure from DNS cache poisoning ICANN housecleaning revokes old DNS security key Oracle said that since its acquisition of Dyn in 2016 and the ensuing acquisition of Zenedge, its engineering teams have been working to integrate Dyn’s products and services into the Oracle Cloud Infrastructure platform. “Enterprises can now leverage the best-in-class DNS, web application security, and email delivery services within Oracle Cloud Infrastructure and enhance their applications with a comprehensive platform to build, scale, and operate their cloud infrastructure," according to Oracle's FAQ on the move. "As a result, Dyn legacy Enterprise services are targeted to be retired on May 31, 2020 with the exception of Internet Intelligence.”To read this article Continue reading

Cisco issues critical security warnings on SD-WAN, DNA Center
Cisco has released two critical warnings about security issues with its SD-WAN and DNA Center software packages. The worse, with a Common Vulnerability Scoring System rating of 9.3 out of 10, is a vulnerability in its Digital Network Architecture (DNA) Center software that could let an unauthenticated attacker connect an unauthorized network device to the subnet designated for cluster services. More about SD-WAN How to buy SD-WAN technology: Key questions to consider when selecting a supplier How to pick an off-site data-backup method SD-Branch: What it is and why you’ll need it What are the options for security SD-WAN? A successful exploit could let an attacker reach internal services that are not hardened for external access, Cisco stated. The vulnerability is due to insufficient access restriction on ports necessary for system operation, and the company discovered the issue during internal security testing, Cisco stated.To read this article in full, please click here

Cisco offers cloud-based security for SD-WAN resources
SAN DIEGO— As many companies look to SD-WAN technology to reduce costs, improve connectivity and streamline branch office access, one of the key requirements will be solid security technologies to protect corporate resources.At its Cisco Live customer event here this week, the company took aim at that need by telling customers it added support for the its cloud-based security gateway – known as Umbrella – to its SD-WAN software offerings. More about SD-WAN How to buy SD-WAN technology: Key questions to consider when selecting a supplier How to pick an off-site data-backup method SD-Branch: What it is and why you’ll need it What are the options for security SD-WAN? At its most basic, SD-WAN lets companies aggregate a variety of network connections – including MPLS, 4G LTE and DSL – into a branch or network-edge location and provides a management software that can turn up new sites, prioritize traffic and set security policies. SD-WAN's driving principle is to simplify the way big companies turn up new links to branch offices, better manage the way those links are utilized – for data, voice or video – and potentially save money in the process.To read this article in full, please Continue reading
