Cisco urges patching flaws in data-center, SD-WAN gear

Cisco has issued a number of critical security advisories for its data center manager and SD-WAN offering customers should deal with now.On the data center side, the most critical – with a threat score of 9.8 out of 10 – involves a vulnerability in the REST API of Cisco Data Center Network Manager (DCNM) could let an unauthenticated, remote attacker bypass authentication and execute arbitrary actions with administrative privileges on an affected device.Cisco DCNM lets customers see and control network connectivity  through a single web-based management console for the company’s Nexus, Multilayer Director Switch, and Unified Computing System products.To read this article in full, please click here

Counterfeit Cisco switches raise network security alarms

In a disconcerting event for IT security professionals, counterfeit versions of Cisco Catalyst 2960-X Series switches were discovered on an unnamed business network, and the fake gear was found to be designed to circumvent typical authentication procedures, according to a report from F-Secure.F-Secure says its investigators found that while the counterfeit Cisco 2960-X units did not have any backdoor-like features, they did employ various measures to fool security controls. For example, one of the units exploited what F-Secure believes to be a previously undiscovered software vulnerability to undermine secure boot processes that provide protection against firmware tampering. To read this article in full, please click here

Options grow for migrating mainframe apps to the cloud

Mainframe users looking to bring legacy applications into the public or private cloud world have a new option: LzLabs, a mainframe software migration vendor.Founded in 2011 and based in Switzerland, LzLabs this week said it's setting up shop in North America to help mainframe users move legacy applications – think COBOL – into the more modern and flexible cloud application environment.Read also: How to plan a software-defined data-center network At the heart of LzLabs' service is its Software Defined Mainframe (SDM), an open-source, Eclipse-based system that's designed to let legacy applications, particularly those without typically available source code, such as COBOL, run in the cloud without recompilation.To read this article in full, please click here

IDC: Covid-19 hits SD-WAN, data center gear; enterprise impact varies

While the previously hot SD-WAN market has slowed and IT budgets overall are under pressure, the COVID-19 pandemic has created demand for other network capabilities such as improved network-management and collaboration tools, according to IDC.The virus has caused recessionary economy that has forced enterprises across the globe to rapidly and dramatically shift their operations, according to Rohit Mehra, vice president, Network Infrastructure at IDC. “The reality of that is we have seen two years of IT digital transformation in two months,” Mehra told the online audience of an IDC webinar about the impact of the pandemic on enterprise networking.To read this article in full, please click here

Fannie Mae’s journey to SD-WAN means less reliance on MPLS and VPNs

About a year and a half ago, some Texas employees of the Federal National Mortgage Association (Fannie Mae) were leaving work early to work at home over the enterprise VNP because it gave them better application performance and less congestion than the office network.That’s also when the agency started moving toward a cloud-first environment and away from its legacy hub-and-spoke WAN.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?To read this article in full, please click here

Cisco warns of Nexus switch security weakness

Cisco is telling customers of its Nexus core data-center switches to fix or work around a vulnerability that could leave the boxes open to a denial of service attack.The vulnerability, found in the Nexus NX-OS software gets a 8.6 score out of 10 on the Common Vulnerability Scoring System, making it a “High” risk problem.Cisco said the vulnerability is due to an affected device unexpectedly decapsulating and processing IP-in-IP packets that are destined to a locally configured IP address. IP in IP is a tunneling protocol that wraps an IP packet within another IP packet.To read this article in full, please click here

Cisco takes aim at supporting SASE

Cisco is embracing the secure-access service edge (SASE) architecture put forth by Gartner with plans to upgrade some of its existing products to reach the goal of delivering access control, security and networking to cloud services.The enterprise shift to SASE will be gradual as they figure out the best way to connect their increasingly remote workforce to distributed resources delivered from corporate data centers and as cloud services, Cisco says.Network pros react to new Cisco certification curriculum “Flexibility will be fundamental as IT chooses among multiple security and networking capabilities that best fit their operations, regulatory requirements, and types of applications,” said Jeff Reed, senior vice president of product, Cisco’s Security Business Group in a blog post. “Security services can be predominantly delivered from the cloud to provide consistent access policies across all types of endpoints. However, globally distributed organizations may need to apply security and routing services differently according to regional requirements.”   To read this article in full, please click here
