Telephone System Is a Bad Example of Hierarchical Addresses

Networking engineers proposing strict hierarchical addressing scheme as a solution to global BGP table explosion often cite the international telephone system numbering plan (E.164) as a perfect example of an addressing plan that uses hierarchy to minimize routing table sizes. Even more, widespread mobile roaming and local number portability indicate that we could solve IP mobility and multihoming if only insert-your-favorite-opinion-here.

US security agencies warn of threats to indusctial, utility control networks

Key US government security organizations are warning industrial control system (ICS)/supervisory control and data acquisition (SCADA)-basednetworks are being threatened by bad actors armed with custom software tools.The Department of Energy (DOE), Cybersecurity and Infrastructure Security Agency (CISA), National Security Agency (NSA) and Federal Bureau of Investigation (FBI) issued a joint warning that certain advanced persistent threat (APT) actors have shown the ability to gain full system access to compromised ICS/SCADA systems.

Nokia pulls most of its business from Russia

Finland-based telecommunications equipment giant Nokia has announced that it would cease most of its operations in Russia, in response to that country’s month-old invasion of Ukraine.Nokia said in a statement that it would suspend equipment deliveries, accept no new orders and move “our limited R&D activities” out of the country, saying that “it has been clear for Nokia since the early days of the invasion of Ukraine that continuing our presence in Russia would not be possible.”Russia accounted for less than 2% of the company’s net sales in 2021, according to Nokia, which added that the move will not affect the bottom line in a significant way, and that the company expects to hit all of its immediate earnings targets going forward.To read this article in full, please click here

Hedge 126: George Michaelson on ISDN

ISDN, while an old technology, is still around in many parts of the world. When will it go away? George Michaelson joins Tom Ammon and Russ White to discuss the end of ISDN. The conversation then veers into old networking technologies, and the importance of ISDN in setting the terms and ideas we use today—ISDN is one of the key technologies around which network engineers built their mental maps of how to build and maintain networks.

The Key to Networking is First Getting a Good Night’s Sleep

Anyone who’s ever gone to a networking event knows that they can be exhausting. You’re constantly meeting new people, exchanging business cards, and trying to make a good impression. It’s no wonder that so many people end up burning out quickly.

The key to networking effectively is actually quite simple: getting a good night’s sleep beforehand.

How much sleep do you need to be at your best for networking events?

Most people need around eight hours of sleep per night to function at their best. However, if you know you have an upcoming networking event, it’s important to get even more sleep than usual. Try to get at least nine or ten hours of sleep the night before. This will help ensure that you’re well-rested and won’t be as likely to feel exhausted during the event.

How can you make sure you get enough sleep?

There are a few different things you can do to make sure you get enough sleep. First, avoid caffeine in the evening. Caffeine can stay in your system for up to eight hours, so it’s best to avoid it after lunchtime.

Second, establish a bedtime routine and stick to it as much as possible. Continue reading

Day Two Cloud 142: OpenZiti Serves Up Zero Trust For Applications (Sponsored)

Today's Day Two Cloud episode bites into OpenZiti, an open-source project that brings zero trust principles to networks and applications. OpenZiti builds an overlay network to enforce zero trust. It has several moving parts including edge routers, a controller, and SDKs. OpenZiti was created by NetFoundry, our sponsor for this episode. Guest Clint Dovholuk takes us through the nitty-gritty of how it works.

Ransomware Attacks: You Can’t Protect What You Can’t See

To combat the rising tide of ransomware attacks, businesses are focusing on their IT inventory for the information they need to properly defend themselves.

Red Hat Insights for Ansible Automation Platform New Report : Modules

Red Hat Insights is a suite of cloud services available on the Red Hat Hybrid Cloud Console, powered by an expert system that is built upon years of data collected from across Red Hat’s worldwide customer base. For Red Hat Ansible Automation Platform customers, it provides predictive analytical reporting of your Ansible automation.

This blog breaks down the new reports that analyze module usage within the Ansible Automation Platform.

In summary, module usage is really important because modules can contain security vulnerabilities and require updates to support new integrations of hardware or software. It is paramount to know which modules you are using in your automation.

Let's look at each report and what each of them can deliver for you.

Reports

Most used modules

Description: The number of job template and task runs, grouped by Ansible module usage.

Use Case: You can use this report to discover which modules are being used the most across your automation, helping you to check things like organization-wide adoption of purpose-built modules over potentially less performant, catch-all solutions.

Example:

This chart shows how the file and gather_facts modules are the most used, but also shows that over the past 6 Continue reading

Cloudflare partners with Kentik to enhance on-demand DDoS protection

We are excited to announce that as of today, network security teams can procure and use Magic Transit, Cloudflare’s industry-leading DDoS mitigation solution, and Kentik’s network observability as an integrated solution. We are excited to help our customers not just with technical simplicity, but business process simplicity as well.

Why monitoring and mitigation?

Distributed Denial of Service (DDoS) attacks are highly disruptive to businesses everywhere. According to the Cloudflare DDoS Attack Trends report, in the first half of 2021 the world witnessed massive ransomware and ransom DDoS attack campaigns that interrupted critical infrastructure, including oil pipelines, healthcare, and financial services. In the second half, we saw a growing swarm of attacks, including one of the most powerful botnets deployed (Meris), with record-breaking network-layer attacks observed on the Cloudflare network.

Along with an increase in severity, there is a proliferation of automated toolkits that make it simple and cheap for anyone to launch these attacks. Detecting and stopping these attacks manually is not effective, and network security engineers are increasingly turning to automated tools to help ensure network and application availability.

DDoS protection has evolved over the years from appliances to hybrid models to fully Internet-native solutions, like Continue reading

Cisco pushes for more recycling of its used gear

Cisco is introducing a new payment scheme to encourage customers to recycling its hardware, alongside a new partner incentive to repurpose or recycle its end-of-use products.The two schemes aim to help Cisco CEO Chuck Robbins build on the vendor’s 2018 sustainability pledge and a commitment to have 100% of hardware returned at the end-of-use.Building the circular economy The Cisco Green Pay payment scheme will see customers offered a 5% incentive on Cisco hardware at the outset of their purchase and a predictable payment strategy over five years. Once the term is up, the product is recovered by Cisco free of charge and the customer receives a certificate confirming that it has entered the circular economy.To read this article in full, please click here
