Five Digital Transformation Trends for 2023
Enterprises will need to bridge operational and technology siloes to meet the needs of extremely demanding employees and customers.MEF Introduces First SASE Standard and Zero Trust Framework
The new SASE service standard accelerates managed service providers' ability to offer robust, unified network and security services with Zero Trust to enterprises.Will 2023 be the year of Artificial Intelligence for InfoSec?
Gartner has been saying that “next big thing” in network security is the increased use of artificial intelligence (AI) and machine learning (ML) technologies for years now… Mainly because these technologies have the potential to revolutionize the way that network security is managed by enabling systems to learn and adapt to new threats in real-time.
One of the main benefits of using AI and ML in network security is that they can help to identify and mitigate threats much faster than traditional methods. This is because they can analyze vast amounts of data in real-time, and detect patterns and anomalies that might indicate the presence of a threat. In addition, they can be programmed to take specific actions in response to these threats, such as blocking access to a particular network resource or alerting security personnel.
Another benefit of using AI and ML is that they can help to reduce the workload of security professionals. By automating many of the tasks currently carried out manually, such as analyzing logs and identifying potential threats, AI and ML technologies can free up time for security professionals to focus on more critical tasks.
However, it is essential to note that using AI and Continue reading

Can ChatGPT debug my code? Can it write better code?
Everyone’s talking about it, so why should I not add something too.
Interview question
ChatGPT is pretty amazing. I asked it an interview question, and it just plain solved it. Well, there was one real world imperfection. I asked it to fix that problem, and then it went off the rails. The more I hinted, the worse the code got.
I won’t give the details here, because I want to keep using the question / topic.
Finding bugs
So I wondered if it could find bugs. First an easy one:
Q:
What's the problem with this C++ code:
int* foo() {
auto ret = new int;
int r2 = *ret * 2;
return &r2;
}
A:
There are several problems with the code you provided:
1. The function foo is returning a pointer to a local variable r2,
which is not safe because the memory for r2 is deallocated when the
function returns. This can cause undefined behavior when you try to
access the returned pointer after the function has returned.
2. The function foo is allocating memory for an integer with new int,
but it is not deallocating that memory before the function
returns. This can lead to a Continue readingThe Power of Continuing Education on Certifications
I’m about six months away from recertifying my CCIE and even though I could just go Emeritus now I’m working on completing some continuing education at the end of the year to push it out another three years. I am once again very thankful that Cisco has this as an option instead of taking a test over and over again as the only option to renew my certifications.
As I embark on another journey to keep myself current in the networking community, I realize that the flexibility that education credits offer is more important that just passing a test or learning a new skill. Employers should also be thrilled that knowledge workers have the ability to work on other skills and be recognized for them. Because there are two different paths that this can lead to.
To Be The Best
One of the things that most professionals recognize with continuing education is that you can leverage your skills to race through things. If you’re already an expert at something like BGP or spanning tree why not take courses to improve the depth of your knowledge? This is part of the reason why there are a number of double CCIEs that Continue reading
Closing out 2022 with our latest Impact Report
To conclude Impact Week, which has been filled with announcements about new initiatives and features that we are thrilled about, today we are publishing our 2022 Impact Report.
In short, the Impact Report is an annual summary highlighting how we are helping build a better Internet and the progress we are making on our environmental, social, and governance priorities. It is where we showcase successes from Cloudflare Impact programs, celebrate awards and recognitions, and explain our approach to fundamental values like transparency and privacy.
We believe that a better Internet is principled, for everyone, and sustainable; these are the three themes around which we constructed the report. The Impact Report also serves as our repository for disclosures consistent with our commitments for the Global Reporting Initiative (GRI), Sustainability Accounting Standards Board (SASB), and UN Global Compact (UNGC).
Check out the full report to:
- Explore how we are expanding the value and scope of our Cloudflare Impact programs

s OpenSLP service: CVE-2019-5544 and CVE-2020-3992. Data Clean Rooms: Enabling Analytics, Protecting Privacy
Data clean rooms offer a way for organizations to collaborate with and share data in a protected environment that preserves privacy and governance. Here's why they are on the rise now.Azure Host-Based SDN: Part 1 – VFP Introduction
Azure Virtual Filtering Platform (VFP) is Microsoft’s
cloud-scale virtual switch operating as a virtual forwarding extension within a
Hyper-V basic vSwitch. Figure 1-1 illustrates an overview of VFP building
blocks and relationships with basic vSwitch. Let’s start the examination from
the VM vm-nwkt-1 perspective. Its vNIC vm-cafe154 has a synthetic interface
eth0 using a NetVSC driver (Network Virtual Service Client). The Hyper-V
vSwitch on the Parent Partition is a Network Virtual Service Provider (NetVSP)
with VM-facing vPorts. Vm-cafe154 is connected to vPort4 over the logical
inter-partition communication channel VMBus. VFP sits in the data path between
VM-facing vPorts and default vPort associated with physical NIC. VFP uses
port-specific Layers for filtering traffic to and from VMs. A VFP Layer is a
Match Action Table (MAT) having a set of policy Rules. Rules consist of
Conditions and Actions and are divided into Groups. Each layer is programmed by independent, centralized Controllers without cross-controller dependencies.
Let’s take a concrete example of Layer/Group/Rule object relationship and management by examining the Network Security Group (NSG) in the ACL Layer. Each NSG has a default group for Infrastructure rules, which allows Intra-VNet traffic, outbound Internet connection, and load balancer communication (health check, etc.). We Continue reading
How Cloudflare advocates for a better Internet
We mean a lot of things when we talk about helping to build a better Internet. Sometimes, it’s about democratizing technologies that were previously only available to the wealthiest and most technologically savvy companies, sometimes it’s about protecting the most vulnerable groups from cyber attacks and online prosecution. And the Internet does not exist in a vacuum.
As a global company, we see the way that the future of the Internet is affected by governments, regulations, and people. If we want to help build a better Internet, we have to make sure that we are in the room, sharing Cloudflare’s perspective in the many places where important conversations about the Internet are happening. And that is why we believe strongly in the value of public policy.
We thought this week would be a great opportunity to share Cloudflare’s principles and our theories behind policy engagement. Because at its core, a public policy approach needs to reflect who the company is through their actions and rhetoric. And as a company, we believe there is real value in helping governments understand how companies work, and helping our employees understand how governments and law-makers work. Especially now, during a time in which many Continue reading
