IBM service uses DNS to deliver multicloud connectivity

IBM is rolling out a new DNS-based service that will let customers securely control connectivity between distributed multicloud environments.NS1 Connect is one of the first fruits from IBM’s acquisition of DNS specialist NS1 earlier this year. The service is aimed at helping organizations set up the best connection between clouds and end users to deliver applications optimized for performance, cost, security and availability.Core to the NS1 Connect package, which will be available Oct. 17, is traffic-steering technology that intelligently distributes DNS traffic across the network. DNS is often described as the Internet’s phone book, working in the background to match the names of web sites that users type into a search box with the corresponding IP address.To read this article in full, please click here

Can anybody stop Nvidia?

When gaming chip maker Nvidia announced a decade ago that it planned a strategic shift to data center AI, there were many questions: Could they build a full-stack, enterprise-grade offering? Was there even a market for AI?After the company’s latest earnings report, the question is whether anybody can challenge Nvidia as the preeminent AI platform provider for both enterprise and hyperscale data centers.Through clever acquisitions, internal hardware/software development, and strategic alliances, Nvidia positioned itself perfectly to take advantage of the generative AI frenzy created by the release of ChatGPT late last year. Neither industry-wide chip shortages, nor the collapse of its proposed $40 billion purchase of chip rival Arm Ltd. had any noticeable effect on Nvidia’s phenomenal growth.To read this article in full, please click here

DNS security poses problems for enterprise IT

Attacks related to Domain Name System infrastructure – such as DNS hijacking, DNS tunneling and DNS amplification attacks – are on the rise, and many IT organizations are questioning the security of their DNS infrastructure.Most IT organizations maintain a variety of DNS infrastructure for public services (websites and internet-accessible services) and private services (Active Directory, file sharing, email). Securing both internal and external DNS infrastructure is critical due to a growing number of threats and vulnerabilities that malicious actors use to target them. Unfortunately, very few organizations are confident in their DNS security.Enterprise Management Associates (EMA) recently examined the issue of DNS security in its newly published research report, “DDI Directions: DNS, DHCP and IP Address Management Strategies for the Multi-Cloud Era.” Based on a survey of 333 IT professionals responsible for DNS, DHCP and IP address management (DDI), the research found that only 31% of DDI managers are fully confident in the security of their DNS infrastructure.To read this article in full, please click here

Intel updates FPGA product line

Intel refreshed its FPGA line-up with cost-optimized offerings, released its FPGA software stack as open source, and added a new processor design based on the RISC-V architecture.The first of the new products is the Agilex 3 family of power- and cost-optimized FPGAs available in compact form factors. Agilex follows the same product-naming convention as the desktop Core series; 3 is the lowest end of the performance spectrum, followed by 5, 7, and 9 series in ascending order.The Agilex 3 family will come with two branches: the B-Series and C-Series. The B-Series FPGAs have higher I/O density in smaller form factors at lower power than other Intel FPGAs​. B-Series FPGAs are targeted for board and system management, including server platform management (PFM) applications.To read this article in full, please click here

Taking control of your fortunes on Linux

The fortune command is generally considered one of the just-for-fun commands that you’ll find on linux systems, but it can prove useful in some interesting ways.How it works Probably most Linux users run the fortune command only when they’re bored, though I’ve known a few who added the fortune command to the end of their .bashrc files so that every login would provide a little quote or a saying that they’d ponder for as much as 30 seconds before proceeding to more serious work.The fortune command is, however, more versatile than many Linux users realize. In fact, most of the responses to typing “fortune” are not really fortunes at all. Rather than predicting your future or even just the outcome of your day, they provide quotes or lighthearted comments.To read this article in full, please click here

Cisco significantly bolsters security portfolio with $28B Splunk buy

Looking to significantly reinforce its security software portfolio, Cisco has struck a $28 billion cash deal to acquire enterprise and cloud protection company Splunk.Founded in 2003, Splunk’s software platform is known for its wide-reaching ability to search, monitor and analyze data from a variety of systems.

How network security can save security dollars

For the last twelve years, 100% of CIOs have said that they expect to spend more on IT security, making security the only category that just keeps on absorbing investment. Every year in the last three years, over 80% of enterprises have said that their IT security still needed improvement. So, like death and taxes, is security spending growth inevitable? If we keep on the way we have, it sure seems like it. But what might change?Let’s start with what’s important to users. External threats, meaning hacking, are a problem for every CIO. Internal threats, from badly behaving employees, are a problem for three out of four. Data theft is a universal fear, and malware that interferes with applications and operations is an important problem for over 90% of CIOs. As far as approaches or targets are concerned, 100% say access security on applications and data is essential and so is regular malware scanning. If you ask CIOs to pick a single thing they think is essential for IT security, it’s access security.To read this article in full, please click here

Using curl and wget commands to download pages from web sites

One of the most versatile tools for collecting data from a server is curl. The “url” portion of the name properly suggests that the command is built to locate data through the URL (uniform resource locater) that you provide. And it doesn’t just communicate with web servers. It supports a wide variety of protocols. This includes HTTP, HTTPS, FTP, FTPS, SCP, SFTP and more. The wget command, though similar in some ways to curl, primarily supports HTTP and FTP protocols.Using the curl command You might use the curl command to: Download files from the internet Run tests to ensure that the remote server is doing what is expected Do some debugging on various problems Log errors for later analysis Back up important files from the server Probably the most obvious thing to do with the curl command is to download a page from a web site for review on the command line. To do this, just enter “curl” followed by the URL of the web site like this (the content below is truncated):To read this article in full, please click here

AMD introduces Epyc server processors for the edge

AMD has formally launched its new Epyc 8004 Series processors, the fourth generation of server processors developed under the Siena codename. They're specifically built for energy-efficient and differentiated platforms such as the intelligent edge, as well as for data center, cloud services, storage and other applications.The 8004 product family ranges from eight cores to 64 cores. The 8004 core design is known as Zen 4c, as in compact. It has fewer cores, fewer PCIe lanes and fewer memory channels, but the payoff is in much lower power requirements.In an era of ever-increasing power consumption, the 8004 series is going in the opposite direction. The product family has thermal design power (TDP) measurements ranging from about 70 to 225 watts. That’s more along the lines of a desktop processor than a server processor, which can often be double that number.To read this article in full, please click here
