Learning Security with Mayur

There's nothing more comforting than indulging in a slice of homemade cake paired with a piping hot cup of coffee or tea. Sounds rejuvenating, right? Take the flour, eggs to beat, powdered sugar and a cup of milk. Follow the recipe and viola the cake is ready to eat... Are you wondering if the focus of this blog has shifted to food recipes rather than security? Well, that’s not the case. However, we can learn a lot from our kitchen friends and apply them to understand quite a few concepts of security. Today we will learn about the various cloud service models and how are they so similar to baking a cake. If you have not heard the term “cloud” , there is nothing to worry about. In the simplest of terms, you can consider cloud as “someone else’s computer - a very big one which has unlimited storage and processing capacity.” The official definition is as follows: “Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of con

Well , most people started talking about privacy only after GDPR came into existence. However , Samuel Warren and Louis Brandeis published “The Right to Privacy” in 1890 in the Harvard Law Review. They set forth the definition of privacy as “the right to be left alone.” This definition , although written in the context of the physical world can easily be extended to the digital world. Through this blogpost , lets try to understand the definition of privacy and its types. We will also explore the origins of privacy so as to better enable to understand the various laws and resolutions passed in this regard. Section 1 of the California Constitution says , “All people are by nature free and independent and have inalienable rights. Among these are enjoying and defending life and liberty, acquiring , possessing and protecting property, and pursuing and obtaining safety , happiness and privacy.” Hence , privacy has been defined as the desire of the people to freely choose the circu

Dear Readers, Your love and support are what drives me to move forward and find new ways to make this blog more engaging for you. As a constant endeavor to help you with the preparation of the certifications such as SSCP, CISSP, CompTIA Security +, CCSP, etc. I have now collaborated with Simpliv.  For those who are unaware, Simpliv is a global online learning marketplace similar to  Udemy. Simpliv believes that learning has no boundaries. It brings learning to any person who wants to learn, whether it is management, technology, life sciences or any other subject of interest. A belief which I share with Simpliv that lead me to choose them for launching my courses on this platform too. Currently, only 1 course on SSCP is live now on the platform. However, around 7-8 courses will be launching in a few weeks time. [ This post will be updated with links of new courses]. Sharing the link for the course. https://www.simpliv.com/itcertification/systems-security-certified-pr

The Recipe is simple. Setup a network. Add a bit of internet to the mix. To improve the taste, add firewalls, IDS, IPS, and some monitoring programs. It's time to divide the network so that it can be served as per the requirements of the guests. Segment one part while segregating the other. Viola… The dish is ready to be served. Well, the dish cannot be served unless and until we learn the differences between network segmentation and segregation. I find them confusing and maybe you would do it. If you do, let’s finish this confusion once and for all through this blog post. I would like to approach this through layman terms rather than confusing myself with all sorts of fancy terms and technologies. If you look at a hotel on a whole, it’s a big building. Now no one person would like to book the entire building completely. So in order to maximize the revenue, the hotel person segments or in a way divides this complete hotel into various smaller portions called rooms. These ro

Paul is flying on an airplane from Bangkok to Hawaii. While the air hostess serves him a glass of champagne, Paul enjoys the calmness of the clouds around him. His flight is about to land in another 20 minutes. The pilot is communicating with the air traffic controller at the Hawaii airport. However, he is not able to connect to him. The traffic controllers are not responding back to him. Meanwhile, frantic calls are underway with the President and other top ministers. The decision is YES. Yes to pay to the hacker whose ransomware has crippled the entire system and thousands of lives are at stake. If you feel that is fiction, it can be, but what is the guarantee that this cannot be a real scenario. In today’s age, everything is possible. We saw hospitals hacked in the UK through ransomware, metro rails displaying ransomware riddled messages, what’s stopping the airports or other critical infrastructure being hacked? The Threat Quantum Airports have always been highly targeted

A credit card sized computer remains hidden in a laboratory connected to its network for a period of 10 months. During these 10 months, the attacker was able to enter into the systems and applications that were not approved for access. The system administrators did not check as to what devices were connected on the network. The attacker then took advantage of the weaknesses in the laboratory’s network to remain undetected for 10 months, stealing 23 files in the process. Two of these files contained information on International Traffic in Arms Regulations, which controls the transfer of military and space-related technology, related to the Mars Science Laboratory Mission. If you are wondering if this is from a fiction novel or a TV series, you are wrong. This is the attack which has happened at NASA. Yes, you read it right. The world’s most advanced space lab was hacked due to an unauthorized Raspberry Pi computer connected to the JPL servers. Welcome to the brave new world wher

Time passes so quickly that it's hard to believe for me that another year has gone by and this blog is now celebrating its 2nd birthday. This journey started two years ago after the completion of my CISSP certification. The year has been full of love and support from all the readers across the globe. This year saw around 90+ posts written on various topics involving security. The focus was however in explaining various topics of CISSP and SSCP in the simplest manner possible. Cybersecurity awareness series, blockchain, DevSecOps, etc. were also focussed upon. There were some months where I slowed down, but what pushed me forward was the love and support from multiple readers across the world. The best thing for a blogger is when he receives a mail from one of the readers who says "Thank you for writing. Your blog has helped me a lot". There are many readers who helped me correct some of the anomalies in the free practice question section while some gave their valua
