Looking ahead to the network technologies of 2023

TH Author , , ,

What’s the single most important thing that enterprises should know about networking in 2023? Forget all that speeds-and-feeds crap you hear from vendors. The answer is that networking is now, and forever, linked to business applications, and those applications are linked now to the way that we use the Internet and the cloud. We’re changing how we distribute and deliver business value via networking, and so network technology will inevitably change too, and this is a good time to look at what to expect.Growth in Internet dependence
First, the Internet is going to get a lot better because it’s going to get a lot more important. It’s not just that the top-end capacities offered will be raised, in many cases above 2 Gbps. Every day, literally, people do more online, and get more interactive, dynamic, interesting, websites to visit and content to consume. Internet availability has been quietly increasing, and in 2023 there will be a significant forward leap there, in large part because people who rely on something get really upset when it’s not working.To read this article in full, please click here READ MORE HERE…

What is Zero Trust Network Architecture (ZTNA)?

TH Author , ,

Zero Trust is a term coined by John Kindervag while he was an analyst at Forrester Research to describe a strategic framework in which nothing on the network is trusted by default – not devices, not end users, not processes. Everything must be authenticated, authorized, verified and continuously monitored.The traditional approach to security was based on the concept of “trust, but verify.” The weakness of this approach is that once someone was authenticated, they were considered trusted and could move laterally to access sensitive data and systems that should have been off-limits.Zero Trust principles change this to “never trust, always verify.” A Zero Trust architecture doesn’t aim to make a system trusted or secure, but rather to eliminate the concept of trust altogether. Zero Trust security models assume that an attacker is present in the environment at all times. Trust is never granted unconditionally or permanently, but must be continually evaluated.To read this article in full, please click here READ MORE HERE…

Data center networking trends to watch for 2023

TH Author , , , , ,

Hybrid and multicloud initiatives will continue to shape enterprise IT in 2023, and the impact on data-center networking will be felt across key areas including security, management, and operations. Network teams are investing in technologies such as SD-WAN and SASE, expanding automation initiatives, and focusing on skills development as more workloads and applications span cloud environments.“The most important core trend in data centers is the recognition that the hybrid cloud model – which combines current transaction processing and database activities with a cloud-hosted front-end element for the user interface – is the model that will dominate over time,” said Tom Nolle, president of CIMI Corp. and a Network World columnist. The industry is seeing a slow modernization of data center applications to support the hybrid-cloud model, Nolle says, “and included in that is greater componentization of those applications, a larger amount of horizontal traffic, and a greater need to manage security within the hosted parts of the application.”To read this article in full, please click here READ MORE HERE…

Palo Alto targets zero-day threats with new firewall software

TH Author , ,

Palo Alto Networks has released next-generation firewall (NGFW) software that includes some 50 new features aimed at helping enterprise organizations battle zero-day threats and advanced malware attacks.The new features are built into the latest version of Palo Alto’s firewall operating system – PAN 11.0 Nova – and include upgraded malware sandboxing for the company’s WildFire malware-analysis service, advanced threat prevention (ATP), and a new cloud access security broker (CASB).WildFire is Palo Alto’s on-prem or cloud-based malware sandbox that is closely integrated with Palo Alto’s firewalls. When a firewall detects anomalies, it sends data to WildFire for analysis. WildFire uses machine learning, static analysis, and other analytics to discover threats, malware and zero-day threats, according to the vendor.To read this article in full, please click here READ MORE HERE…

2022 holiday DDoS protection guide

TH Author , , , , ,

The holiday season is an exciting time for many people as they get to relax, connect with friends and family, and celebrate traditions. Organizations also have much to rejoice about during the holidays (for example, more sales for retailers and more players for gaming companies). Unfortunately, cyber attackers also look forward to this time of year to celebrate an emerging holiday tradition—distributed denial-of-service (DDoS) attacks.

Should security systems be the network?

TH Author ,

Recently during a research interview with a small but fast-growing business, for the first time I encountered an organization with a “no-network-vendor” network. That is, instead of using Cisco or Dell or even a white-box solution for switching and routing, the company deployed only Fortinet equipment for its entire network. That is, every network component is part of the security infrastructure for them.They built the network this way not just to bake security into its core (a great idea in itself) but also for:
ease of management: they have one tool, it manages every component
ease of deployment: they have only two or three versions of each appliance, all the same except for capacity and port count
ease of expansion to new locations: every site is the same as any other site of similar size

They have a small stock of replacement appliances on the shelf, with which they provide rapid recovery for all locations. They could easily also consume security-operations center as-a-service, and use professional services for nearly all the rest of their network operations. In essence, their security solution could become their complete network solution as well.To read this article in full, please click here READ MORE HERE…

IoT security strategy from those who use connected devices

TH Author ,

Freeman Health System has around 8,000 connected medical devices in its 30 facilities in Missouri, Oklahoma, and Kansas. Many of these devices have the potential to turn deadly at any moment. “That’s the doomsday scenario that everyone is afraid of,” says Skip Rollins, the hospital chain’s CIO and CISO.Rollins would love to be able to scan the devices for vulnerabilities and install security software on them to ensure that they aren’t being hacked. But he can’t.”The vendors in this space are very uncooperative,” he says. “They all have proprietary operating systems and proprietary tools. We can’t scan these devices. We can’t put security software on these devices. We can’t see anything they’re doing. And the vendors intentionally deliver them that way.”To read this article in full, please click here READ MORE HERE…
