Moving away from VPNs as a means to protect corporate networks at the perimeter and moving toward zero-trust network access requires careful enterprise planning and may require implementing technologies that are new to individual organizations.ZTNA employs identity-based authentication to establish trust with entities trying to access the network and grants each authorized entity access only to the data and applications they require to accomplish their tasks. It also provides new tools for IT to control access to sensitive data by those entities that are deemed trusted.To read this article in full, please click here READ MORE HERE…

Who’s selling SASE and what do you get?

Secure access service edge (SASE) architecture rolls networking and security into a cloud service, making it easier for enterprises to provide simple, secure access to corporate resources, but it’s still in its infancy. Vendors and service providers sell offerings that they call SASE, but what they actually provide and how they provide it varies widely.SASE—pronounced “sassy”- is a term coined last year by Gartner, and it combines software-defined WAN (SD-WAN) with access control and security, all bundled as a cloud service.To read this article in full, please click here READ MORE HERE…

Survey: Zero Trust benefits remote work during pandemic

(Editor’s note: An August 2020 Enterprise Management Associates survey of 252 North American and European IT professionals found that most had accelerated their adoption of Zero Trust networking framework. This article by EMA Vice President of Research Networking Shamus McGillicuddy further details the results of the “Enterprise Zero Trust Networking Strategies: Secure Remote Access and Network Segmentation” report.)The COVID-19 pandemic has prompted 60% of enterprises to accelerate their Zero Trust networking strategies. Just 15% of organizations slowed down in response to the public-health crisis, and 25% reported no effect, according to Enterprise Management Associates research.To read this article in full, please click here READ MORE HERE…

Juniper upgrades security software with threat intelligence, VPN package

Juniper Networks has added new components to its security portfolio to help customers get a better handle on potential threats as well as improve risk detection and response.The new products are aimed at figuring out who and what devices are on the network and then offering the security intelligence to help them address threats at every point on the network, said Samantha Madrid vice president of product management in the Security Business & Strategy business at Juniper Networks.Security is always a challenge but even more so now when customers have mass-scale remote workforces, Madrid said.

Cisco turns out security patches 25 high-threat flaws for IOS, IOS XE

If you are a security admin with lots of systems running Cisco IOS and IOS XE software today is decidedly not your day.Cisco this week posted 25 “High” rated security advisories that stem from 34 vulnerabilities the company suggests should be fixed as soon as possible. The vulnerabilities impact a wide-range of Cisco gear as IOS and IOS XE are the company’s most widely used operating systems. The warnings affect firewalls, wireless access points and switches.Network pros react to new Cisco certification curriculum
For example, one of the highest rated threats–with an 8.6 out of 10 threat level, are multiple vulnerabilities in the Zone-Based Firewall feature of Cisco IOS XE Software that could let an remote attacker to cause the device to reload or stop forwarding traffic through the firewall,resulting in a denial of service (DoS).To read this article in full, please click here READ MORE HERE…

What is SASE? A cloud service that marries SD-WAN with security

Secure access service edge (SASE) is a network architecture that rolls software-defined wide area networking (SD-WAN) and security into a cloud service that promises simplified WAN deployment, improved efficiency and security, and to provide appropriate bandwidth per application.Because it’s a cloud service, SASE (pronounced “sassy”) can be readily scaled up and scaled down and billed based on usage. As a result, it can be an attractive option in a time of rapid change.[Get regularly scheduled insights by signing up for Network World newsletters.]
While some vendors in this space offer hardware devices to connect at-home employees and corporate data centers to their SASE networks, most vendors handle the connections through software clients or virtual appliances.To read this article in full, please click here READ MORE HERE…

How the network can support zero trust

Simply stated, zero trust calls for verifying every user and device that tries to access the network and enforcing strict access-control and identity management that limits authorized users to accessing only those resources they need to do their jobs.Zero trust is an architecture, so there are many potential solutions available, but this is a look at those that fit in the realm of networking.[Get regularly scheduled insights by signing up for Network World newsletters.]
Least privilege
One broad principle of zero trust is least privilege, which is granting individuals access to just enough resources to carry out their jobs and nothing more. One way to accomplish this is network segmentation, which breaks the network into unconnected sections based on authentication, trust, user role, and topology. If implemented effectively, it can isolate a host on a segment and minimize its lateral or east–west communications, thereby limiting the “blast radius” of collateral damage if a host is compromised. Because hosts and applications can reach only the limited resources they are authorized to access, segmentation prevents attackers from gaining a foothold into the rest of the network.To read this article in full, please click here READ MORE HERE…

Are newer medical IoT devices less secure than old ones?

Experts differ on whether older connected medical devices or newer ones are more to blame for making healthcare networks more vulnerable to cyberattack.The classic narrative of insecure IoT centers on the integration of older devices into the network. In some industries, those devices pre-date the internet, sometimes by a considerable length of time, so it’s hardly surprising that businesses face a lot of challenges in securing them against remote compromise.To read this article in full, please click here READ MORE HERE…
