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 reading

The 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

Data center networking trends to watch for 2023

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

What is Cloud Computing? According to ChatGPT.

DALL-E picture generated from the answer.

I was curious, given all the ChatGPT love, what it would make of some of our favorite topics. I was both impressed and unimpressed.

Impressed. ChatGPT instantly generated an response that might make a good answer in a Miss Universe contest. You know, the kind of answer delivered with a radiant smile calculated to offend no one yet still sounds comprehensive and deep.

Unimpressed. The answers are a mile wide and an inch deep. There's not a lot of insight. It's more of a zeitgeist oracle. Nothing wrong with that, but I don't think we'll be unemployed soon. It's as many have predicted about AI/ML. These are tools to augment us, flawed humans, not replace us...yet.

Thank you for agreeing to be interviewed today.

You're welcome! I'm happy to answer any questions you have. Please go ahead and ask your first question.

BrandPost: How AI, Automation, and Zero Trust Can Improve Enterprise Networks

The cyberthreat landscape weighs heavily on the minds of business and IT leaders — and for good reason. Statista reports that in this year’s third quarter alone, nearly 15 million data records were exposed worldwide.The risk of data breaches places intense pressure on IT and security teams to ensure corporate networks are not only protected, but also kept up to date. That’s a tall order given the increasingly complex network architectures that mix on-premises and cloud infrastructure. In addition, hybrid workforces have created multiple paths for data and apps traffic that must be secured.To read this article in full, please click here

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

The unintended consequences of blocking IP addresses

In late August 2022, Cloudflare’s customer support team began to receive complaints about sites on our network being down in Austria. Our team immediately went into action to try to identify the source of what looked from the outside like a partial Internet outage in Austria. We quickly realized that it was an issue with local Austrian Internet Service Providers.

But the service disruption wasn’t the result of a technical problem. As we later learned from media reports, what we were seeing was the result of a court order. Without any notice to Cloudflare, an Austrian court had ordered Austrian Internet Service Providers (ISPs) to block 11 of Cloudflare’s IP addresses.

In an attempt to block 14 websites that copyright holders argued were violating copyright, the court-ordered IP block rendered thousands of websites inaccessible to ordinary Internet users in Austria over a two-day period. What did the thousands of other sites do wrong? Nothing. They were a temporary casualty of the failure to build legal remedies and systems that reflect the Internet’s actual architecture.

Today, we are going to dive into a discussion of IP blocking: why we see it, what it is, what it does, who it affects, Continue reading
