Cryptography has been here since we are, we have to remember that to break a cryptography system was the objective of the first computers but also that cryptography and security are always related on iT or other for example: Every poker player should learn a bit about cryptography. Because, in a way, playing poker is actually a form of cryptography. Let me explain. Cryptography is the science of encoding information. Typically encryption is used to encode communications between two parties so that a third party is unable to understand it. For millennia, people have been trying to encrypt their communications—and the field of cryptography has become increasingly important over the years. All of the innovation in cryptography is designed to address one problem. There is an inherent tradeoff between ease-of-use of a cryptographic method and its security. Interestingly, if you are interested only in security—making sure that no one can possibly break your code—and not at all in ea...
Just because it is secure we should always use https, actually right now as developers we have many options to use this protocol for free (GCP, Let's Encrypt). But, what it is http? Hyper Text Transfer Protocol Secure (HTTPS) is the secure version of HTTP, the protocol over which data is sent between your browser and the website that you are connected to. The 'S' at the end of HTTPS stands for 'Secure'. It means all communications between your browser and the website are encrypted. HTTPS is often used to protect highly confidential online transactions like online banking and online shopping order forms. Web browsers such as Internet Explorer, Firefox and Chrome also display a padlock icon in the address bar to visually indicate that a HTTPS connection is in effect. Benefits Customer information, like credit card numbers, is encrypted and cannot be intercepted Visitors can verify you are a registered business and that you own the domain Customers are more...
TC2027 Work with Ken is a complete different way to learn, it challenge your self to improve and to learn exploring the world/internet in a DIY way. I really enjoyed taking the course with him because it was a easy way to learn and to complete the course not to get a good grade but to get the knowledge expect to receive on this course. Course objective: Upon completion of this course, students will have gained an overview of the area of computer security and the basic knowledge needed to understand the risks, threats and vulnerabilities of computer systems in today's world, as well as the controls and protection methods against possible attacks, which are indispensable for these systems to work properly in contemporary companies. They will also be familiar with the existing national and international laws related to computer system security. Yes, for me the course objective was accomplished, and I strongly recommend to take any possible course with Ken, not only because h...
