Cisco buys Internet BGP monitoring firm Code BGP

Aiming to bolster its assessment of Internet traffic health, Cisco has acquired Code BGP, a privately held BGP monitoring startup, for an undisclosed amount.Code BGP will slide into Cisco’s ThousandEyes network intelligence product portfolio and bring a cloud-based platform that, among other features, maintains an inventory of IP address prefixes, peerings and outbound policies of an organization via configured sources, like BGP feeds. Border Gateway Protocol (BGP) tells Internet traffic what route to take, and the BGP best-path selection algorithm determines the optimal routes to use for traffic forwarding.Then, the system lets customers see and interact with this inventory in real-time through an open API and bring real-time detection of BGP hijacking, route leaks, and other BGP issues according to the company. Adding such capabilities will let ThousandEyes further expand its BGP monitoring and incident analysis capabilities to maintain health of the Internet as well as key applications and services, according to Joe Vaccaro vice president of products for Cisco’s ThousandEyes in a blog about the acquisition. To read this article in full, please click here

GigaIO introduces single-node AI supercomputer

Installation and configuration of high-performance computing (HPC) systems can be a considerable challenge that requires skilled IT pros to set up the software stack, for example, and optimize it for maximum performance – it isn't like building a PC with parts bought off NewEgg.GigaIO, which specializes in infrastructure for AI and technical computing, is looking to simplify the task. The vendor recently announced a self-contained, single-node system with 32 configured GPUs in the box to offer simplified deployment of AI and supercomputing resources.Up to now, the only way to harness 32 GPUs would require four servers with eight GPUs apiece. There would be latency to contend with, as the servers communicate over networking protocols, and all that hardware would consume floor space.To read this article in full, please click here

Network giants unite to fight security risks

A group of industry stalwarts is banding together to help enterprises, services providers and telcos fight cyber foes.The Network Resilience Coalition includes AT&T, Broadcom, BT Group, Cisco Systems, Fortinet, Intel, Juniper Networks, Lumen Technologies, Palo Alto Networks, Verizon and VMware. Its aim is to deliver open and collaborative techniques to help improve the security of network hardware and software across the industry.The coalition was brought together under the Center for Cybersecurity Policy & Law, a nonprofit organization dedicated to improving the security of networks, devices and critical infrastructure. The Center has a broad security mission, but at least for now, it wants the Resilience group to focus on routers, switches and firewalls that are older, may have reached end-of-life vendor support, or have been overlooked for security patching or replacement. To read this article in full, please click here

The real risk of AI in network operations

OK, you used to worry about nuclear war, then pandemics, then maybe an asteroid hitting earth or the sun going nova. Now, some want you to add AI to the list of things to worry about, and yes, you should probably do that. I’d hold off on worrying that AI will end life on earth, but users themselves tell me that AI does pose some risks, particularly the current ultra-hot “generative AI” that ChatGPT popularized. That’s particularly true for those who want to apply it to network operations.I got input from 197 senior IT and network professionals over the last month, and none of them believed that AI could lead to the mass extinction of humanity. Well over half said that they hadn’t seen any crippling long-term downsides to AI use, and all of them said that their company used AI “somewhere.” Thirty-four offered real insight into the use of AI in network operations, and I think this group offers us the best look at AI in network missions.To read this article in full, please click here

EnGenius to release Wi-Fi 7 router for the enterprise

Enterprise networking hardware vendor EnGenuis will release one of the first Wi-Fi 7-enabled routers for business use, the company announced this week.The ECW536 uses the Qualcomm Networking Pro 1220 chipset, and features a 4x4x4 antenna configuration. It’s got two 10Gb ethernet ports, and boasts several security enhancements, including business-class encryption protocols, RADIUS and isolated guest access.The main draw, however, is Wi-Fi 7 connectivity. Wi-Fi 7, also known as 802.11be, is the latest and greatest Wi-Fi specification, although official certification from the IEEE isn’t expected to start until the second half of 2024. The key upgrades in Wi-Fi 7 include wider channels (up to 320MHz), 4K quadrature amplitude modulation rather than 1K, and muiltilink operation, which uses multiple radio bands at the same time to serve one connection. All that adds up to a substantially increased theoretical throughput peak, at 46Gbps.To read this article in full, please click here

Assigning sudo privilege to users on Linux

The sudo command is a very important command on Linux systems. You might say that it allows users to run privileged commands without logging in as root, and that is true. However, the more important point is that it allows individuals to manage Linux systems – adding accounts, running updates, installing applications and backing up the system – without requiring these things be done using the root account. This is consistent with the policy that says root privilege should only be used as needed and that no one should simply log in as root and run all of their commands. Doing routine work using the root account is considered dangerous because any typos or commands run in the wrong location can have very serious consequences.To read this article in full, please click here

UK competition agency provisionally OKs Broadcom’s $6B VMware acquisition

The UK’s Competition Market Authority (CMA) has provisionally cleared Broadcom’s proposed acquisition of VMWare, paving the way for the $61 billion deal to go ahead.In November 2022, the CMA announced it was launching an in-depth investigation into the proposed deal, looking into whether the proposed merger “may be expected to result in a substantial lessening of competition within any market or markets in the United Kingdom for goods or services.”In particular, the CMA was concerned that the deal could harm the ability of Broadcom’s rivals to compete with VMware’s server virtualisation software, and if there would be a potential financial benefit to Broadcom and VMware if they were to make rival products work less well with VMware’s softwareTo read this article in full, please click here

Gartner: Generative AI not yet influencing IT spending, but enterprises should plan for it

While the hype around generative AI is palpable, enterprise IT spending so far has not been impacted by it.That is one of the main takeaways from Gartner’s quarterly IT spending forecast, which finds that worldwide IT spending is projected to total $4.7 trillion in 2023, an increase of 4.3% from 2022.Data center systems spending was down slightly year-over-year, but most other enterprise spending will increase, including software, IT and communications services outlay. according to the research firm.“IT projects are shifting from a focus on external facing deliverables such as revenue and customer experience, to more inward facing efforts focused on optimization,” said John-David Lovelock, distinguished VP analyst at Gartner, in a statement.To read this article in full, please click here

Cisco hosts containerized firewall on Catalyst switches to protect mixed IT/OT networks

Cisco announced a containerized firewall package for its venerable Catalyst switch family that’s designed to help enterprise customers with mixed IT and OT systems more easily segment network resources and save money by consolidating network and security deployments.Specifically, Cisco built a Docker-based container for its Secure Firewall Adaptive Security Appliance (ASA) that can be hosted on its Catalyst 9300 access switches. Cisco Secure Firewall ASA combines firewall, antivirus, intrusion prevention, encryption and virtual private network (VPN) support.The firewall supports up to 10 logical interfaces, which can be used for segmentation. This segmentation helps limit the ability of an attacker to move laterally within the network by containing any breach to a specific zone, wrote Pal Lakatos-Toth, an engineering product manager with Cisco’s security business group, in a blog about the news.To read this article in full, please click here

Creating a directory tree with a single command

The mkdir command can do more than create a single directory. It can create multiple directories at once and can even create an entire directory structure with a single command. The required command will be a tad complex, but not particularly challenging.NOTE: If you try to set up a multi-level directory structure with a command like the one shown below, it won't work if the initial directories ("this" and "that") don't already exist.$ mkdir this/that/the_othermkdir: cannot create directory ‘this/that/the_other’: No such file or directory Add a -p (for "parents") and the missing directories will be created and your this/that/the_other directory structure will be set up in your current directory as intended.To read this article in full, please click here
