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 READ MORE HERE…

Ripple20 TCP/IP flaws can be patched but still threaten IoT devices

A set of serious network security vulnerabilities collectively known as Ripple20 roiled the IoT landscape when they came to light last week, and the problems they pose for IoT-equipped businesses could be both dangerous and difficult to solve.Ripple20 was originally discovered by Israel-based security company JSOF in September 2019. It affects a lightweight, proprietary TCP/IP library created by a small company in Ohio called Treck, which has issued a patch for the vulnerabilities. Several of those vulnerabilities would allow for remote-code execution, allowing for data theft, malicious takeovers and more, said the security vendor.That, however, isn’t the end of the problem. The TCP/IP library that contains the vulnerabilities has been used in a huge range of connected devices, from medical devices to industrial control systems to printers, and actually delivering and applying the patch is a vast undertaking. JSOF said that “hundreds of millions” of devices could be affected. Many devices don’t have the capacity to receive remote patches, and Terry Dunlap, co-founder of security vendor ReFirm Labs, said that there are numerous hurdles to getting patches onto older equipment in particular.To read this article in full, please click here READ MORE HERE…

Beyond the three critical advisories, 20 have a “High” impact rating. Cisco said that one vulnerability affects Cisco IOS, IOS XE, IOS XR, and NX-OS Software. Five vulnerabilities affect both Cisco IOS and IOS XE Software. Six vulnerabilities affect Cisco IOS Software and 10 affect Cisco IOS XE Software. Three vulnerabilities affect the Cisco IOx application environment.To read this article in full, please click here READ MORE 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 READ MORE HERE…

Healthcare company pivots quickly to support remote workers

Security and performance concerns made it challenging for TrialCard to enable its employees to work from home when the COVID-19 pandemic hit.Customer service agents use a voice-over-IP phone and thin-client computer, both of which were designed to work in an on-premises office environment. “They need those systems to do their day-to-day job,” says Ryan Van Dynhoven, director of infrastructure at TrialCard, a Morrisville, N.C.-based company that helps pharmaceutical manufacturers connect with patients, including providing patient support and clinical trial services.

SASE could bolster security for remote workers

The coronavirus pandemic has accelerated some companies’ plans to adopt secure access service edge (SASE).Last summer, Gartner estimated SASE adoption at less than 1% of enterprises and said it would take five to 10 years before the technology reaches mainstream. But today, SASE is one of the main topics of client interest, according to Gartner analyst John Wheeler.
