What Is a Man in the Middle (MITM) Attack?
Simply put, MITM is an attack in which a third party gains access to the communications between two other parties, without either of those parties realising it. The third party might read the contents of the communication, or in some cases also manipulate it. So, for example, if Gerald sends Leila a message, intending it to be private, and Max intercepts the message, reads it, and passes it on to Leila, that would be a MITM attack. If Gerald wants to transfer £100 to Leila’s bank account, and Max intercepts the transaction and replaces Leila’s account number with his own, that would also be a MITM attack (in this case, Max is putting himself ‘in the middle’ between Gerald and his bank).
Why should I care?
Partly because MITM attacks can undermine so much of our modern way of life. In a connected life, we depend on the reliability and security of every connection. It’s not just about your conversations, messages and emails, either. If you can’t trust the connections you make to websites and online services, you may be vulnerable to fraud or impersonation, and if your connected devices and objects can’t communicate securely and reliably, they may put Continue reading
Guest blog on network automation at THG Tech
Hello my friend,
I’m very proud of working for THG as we are developing really outstanding technical solutions with a high level of automation. If you run massive-scale networks (like we do in the data centre field), the automation is a single option to survive.
These days many people speak about network automation, but what is it in a nutshell? What role does it play? What are the customer expectations to the network and IT business related to the network automation.
Some answers to these questions and many more useful and interesting information you can find in my guest blog in THG Tech blog
Follow me there as well, if you like the post.
Support us
P.S.
If you have further questions or you need help with your networks, I’m happy to assist you, just send me message. Also don’t forget to share the article on your social media, if you like it.
BR,
Anton Karneliuk

Congratulations to Roy Lexmond on Passing CCDE Practical Exam!
I am very glad to announce that Roy Lexmond from my April CCDE training class passed CCDE Practical exam yesterday in France.
Below is his success story and here is his earlier feedback for the class. I should say that He really likes the design and open to learn new things and very clever.
Please join me to congratulate Roy for his great achievement!
On 19th May in France (Paris) I passed CCDE practical exam. My preparation was done with the cisco learning network excelsheet, Ciscolive video’s, internetworkexpert SP&CCDE courses, Orhan Ergun CCDE Bootcamp and www.orhanergun.net. I attended the Orhan Ergun bootcamp in April-May with lots of great people which helped me prepare well. I really think that the bootcamp helped me to focus on key technologies and discuss them with other people (very important for me) and to understand how to approach the exam.
It was a challenge and took me 2 years, my satisfaction is extreme! and learned alot during those 2 years and still learning. My next goal will be CCIE-SP wich covers some great content inline with the topics the CCDE already covered.

Flat/Single Area OSPF network is not a problem!
Flat OSPF network, or single area OSPF networks are real. In fact most of the OSPF network today deployed, is flat OSPF networks. But how many routers can be placed safely in an OSPF area ? Any number from the real world OSPF deployment ? I will share in this post.
Let me explain what it is first and then will share you some numbers from the real network which I engaged recently.
As you might know, OSPF has two levels of hierarchy. Backbone and Non-Backbone areas.
Why Non-Backbone Areas are used in OSPF?
The reason is scalability and manageability. At least in theory. I don’t see so many multi area OSPF design though I teach in very detail in my CCDE classes. But that is for the exam purpose.
There are some very large scale networks use OSPF for scalability, so, IP but satellite (Sometimes called an Access POP) POPs are in Non-Backbone area they place.
But there is manageability aspects of having multi area OSPF design. They group their slow speed access and metro or aggregation networks in different OSPF areas and place high speed backbone/core routers in a backbone OSPF area (Area 0).
But, we generally forget Continue reading
The EVPN Dilemma
Got an interesting set of questions from a networking engineer who got stuck with the infamous “let’s push the **** down the stack” challenge:
So I am a rather green network engineer trying to solve the typical layer two stretch problem.
I could start the usual “friends don’t let friends stretch layer-2” or “your business doesn’t really need that” windmill fight, but let’s focus on how the vendors are trying to sell him the “perfect” solution:

Prevent lateral compromise with microsegmentation
It’s an unfortunate reality of information security: Eventually, everyone gets compromised. Manufacturers, banks, tech support companies, retail giants, power plants, municipal governments … these are just some of the sectors that have been affected by high-profile data breaches in recent months. Everyone gets hacked. You will, too.
This isn’t cause for despair. It simply means that effective security has to focus on more than just intrusion prevention. Hackers will eventually get into any network, if they’re willing to spend enough time and money doing so. But whether or not they get anything useful once they’ve gained entry—that’s another story.
Good network design can minimize the damage incurred during an attack. There are more ways to approach this than will fit in a single article, so this blog will only focus on network segmentation, and its smaller sibling, microsegmentation.
What is network segmentation?
Network segmentation is the practice of dividing a network into one or more subsections. Each subsection usually contains different kinds of resources and has different policies about who has access to that segment. There are a variety of ways to accomplish the division.
Network segmentation runs along a spectrum from the purely physical to the purely logical. The Continue reading
