Nokia Service Routing Certification and my experience

Introduction 

   Many times I heard that certification is just wasting time. And only real experience does matter. Of course, real experience is important. But often It’s so hard to get experience. E.g. your current job can’t give you opportunities to work with some technologies and you can’t get a new promotion or change a job, because you don’t have some experience. A typical loop. And in my opinion, certification is one of the suitable tools to break this loop and expand your opportunities.

Benefits of every certification:

    - We always need motivation for learning something. Every certification consists of several levels. Step by step approach. Levels are goals for us. And it helps to keep motivation on a high level. And every achieved level helps to feel more confident.
    - Every certification program has proper learning tools. Self-study guides, books, online/offline courses, etc. It helps to save time so we can just start to study.
    - Certification is not the main goal. Preparing is the main goal. And preparing results. For example, notes. Notes were useful before exams as well as they will be useful in the future.

Dealing with Cloud Challenges

Here’s a message I got from one of my subscribers (probably based on one of my recent public cloud rants):

I often think the cloud stuff has been sent to try us in IT – the struggle could be tough enough when we were dealing with waterfall development and monolithic projects. When products took years to develop, and years to understand.

And now we’re being asked to be agile and learn new stuff all the time about moving targets that barely have documentation at all, never mind accurate doco! We had obviously got into our comfort zone and needed shaking out of it!

Always interested to hear your experiences with the cloud networking though – it’s what I subscribed to ipspace.net for TBH as I think it’s the most complete reference source for that purpose and a vital part of enterprise networking these days!

It’s always extremely nice to hear someone finds your work valuable ;) Thanks a million!

Report: 5G network slicing could leave flaws for bad actors to exploit

5G networks that incorporate legacy technology could be vulnerable to compromise via a lack of mapping between transport and application layers, according to a report by Ireland-based AdaptiveMobile Security. 5G resources What is 5G?

Dridex Reloaded: Analysis of a New Dridex Campaign

Dridex is a banking Trojan. After almost a decade since it was first discovered, the threat is still active. According to a report published by Check Point [1], Dridex was one of the most prevalent malware in 2020. The recent Dridex campaign detected by VMware demonstrates that this ongoing threat constantly evolves with new tactics, techniques, and procedures (TTPs), which exhibit great differences with respect to the variants we’ve collected from campaigns since April 2020 (as discussed in the section Comparison with old Dridex samples). 

In this blog post, we first examine the recent Dridex attack by looking into some of VMware’s NSX Advanced Threat Prevention telemetry, which showcases the magnitude of the campaign. We then present the analysis for the most distinctive aspects of the attack, from the techniques leveraged by the XLSM downloader to the main functionality of the DLL payloads. Finally, we provide a comparison to some other Dridex variants seen in the past, which leads to the conclusion that the Dridex variant from the January 2021 campaign is very different from previous variants.

The Insecurity of Ambiguous Standards

Why are networks so insecure?

One reason is we don’t take network security seriously. We just don’t think of the network as a serious target of attack. Or we think of security as a problem “over there,” something that exists in the application realm, that needs to be solved by application developers. Or we think the consequences of a network security breach as “well, they can DDoS us, and then we can figure out how to move load around, so if we build with resilience (enough redundancy) we’re already taking care of our security issues.” Or we put our trust in the firewall, which sits there like some magic box solving all our problems.

The problem is–none of this is true. In any system where overall security is important, defense-in-depth is the key to building a secure system. No single part of the system bears the “primary responsibility” for “security.” The network is certainly a part of any defense-in-depth scheme that is going to work.

Which means network protocols need to be secure, at least in some sense, as well. I don’t mean “secure” in the sense of privacy—routes are not (generally) personally identifiable information (there are always Continue reading

6G: Vast and mysterious promises

But 5G’s seemingly interminable rollout should not preclude wildly premature and breathless anticipation over its successor. Let’s face it, the time will come when we’ll all be complaining about the limitations of puny little 5G.

The Week in Internet News: Facebook Calls for Changes in Legal Protections for User Content

Rewriting the rules: Facebook, during a hearing in the U.S. Congress, called on lawmakers to revamp Section 230 of the Communications Decency Act of 1996, which protects websites from lawsuits for content posted by users, NBC News reports. Websites should be protected if they adopt user moderation practices largely in line with Facebook’s own rules, ZDNet noted. The change could give Facebook an advantage while upending much of the rest of the Internet, The Verge suggested.

Competition in space: The competition among satellite-based broadband providers is heating up, with OneWeb launching 36 new satellites from eastern Russia, The BBC reports. The company, now primarily owned by Indian conglomerate Bharti Global and the U.K. government, now has 146 broadband satellites deployed. The company plans to offer broadband service later this year to northern latitudes, including the U.K., Northern Europe, Alaska, Canada, and other areas. Meanwhile, three rural counties in North Carolina are testing broadband service from SpaceX, another satellite provider, as a way to provide Internet service to students, GCN says.

Bad virus information: Facebook and Twitter have removed millions of posts containing misinformation about COVID-19 in recent months, The Straits Times reports. Since last year, Continue reading

A new Cloudflare Web Application Firewall

A new Cloudflare Web Application Firewall
A new Cloudflare Web Application Firewall

The Cloudflare Web Application Firewall (WAF) blocks more than 57 billion cyber threats per day. That is 650k blocked HTTP requests per second. The original code that filters this traffic was written by Cloudflare’s now CTO and the WAF has since received many accolades including the highest score for ability to execute in the 2020 Gartner Magic Quadrant for WAF.

Because we value replacing code when it is no longer as maintainable, performant, or scalable as it once was, we regularly rewrite key parts of the Cloudflare stack. That’s necessary as our enormous growth makes yesterday’s solutions unworkable. For some time, we have been working on replacing that original LuaJIT code John wrote with new code, written in Rust, along with an improved UI.

We are now excited to announce a new Cloudflare Web Application Firewall.

Starting today, 10% of newly created accounts on Cloudflare will be given access to the new WAF whenever a Pro plan zone or above is added. This percentage will increase to 100% of new accounts over the month of April, after which migration efforts will commence for existing customers. Enterprise customers may migrate early by contacting their account team.

Playing games with Tensorflow

As a fun project, I recently built a web app to play checkers online against the computer. This post tries to outline the methodology I used. If you want to checkout the results, I would encourage you to try the web link above, change the difficulty level to ‘hard’ and play a round against the computer. You will be playing against a very simple neural network model that is, as far as I can tell, reasonably effective.

The standard approach to developing a game AI for something like board games is the “MiniMax” algorithm. Implementing “MiniMax” for a game like checkers is a relatively simple task; one needs to components:

  • A method of generating valid moves for a play given a board position;
  • A scorer function that evaluates the “goodness” of a given board position for a play;

There are multiple sets of possible rules for the game of checkers. I used the “Spanish draughts” rule set popular in Portugal: men move forward only; flying kings and mandatory moves on a 8×8 board. The minimax algorithm is independent of the particular rule-set used.

The scorer function must be able to look at a given player position and determine a score. Continue reading
