  What is digital twin? Digital twin is increasingly becoming popular since 2018, as the virtual replicas of physical assets. Simply said, this buzz word refers to a technology that helps carry out features like device simulation during development, ingestion of real-world data about a physical object or system as inputs and producing the outputs or simulations based on those inputs helping scientists and IT professionals run simulations before actual devices are built and deployed. Digital twin technology has now moved to multiple industries and vastly merging in the Internet of Things, artificial intelligence and data analytics helping augment deployments for peak efficiency and create other what-if scenarios. Via simulation of real object and its interactions with its surroundings, this technology helps provide a more accurate representation of the shape an object than a physical replica. The power of digital twins can be extended to virtually any technology such as clou...

1.     Introduction to zero trust: A more and more raging buzz word in the world of information security, Zero Trust Architecture refers to the “defense in depth” approach of implementing security concepts removing the process of automatically trusting actors and devices integrated in network. Zero trust architecture provides a thorough end to end approach to enterprise resource and data security controls interwoven around identity (person and nonperson entities), credentials, access management, operations, endpoints, hosting environments, and the interconnecting infrastructure. Zero trust leads to ultimately verifying every single component trying to connect to the system before granting access. Relying on fine grained methods such as micro-segmentation and granular perimeter enforcement based on users, zero trust helps to control security over controls such as trusting a user, machine or application for gaining access to a part of the enterprise network. Zero ...

Introduction to digital wallets  Digital wallet, also referred as "e-Wallet" allows people to perform electronic transactions without the need to have physical cards. Not only does it allows to perform payment and transactions, but also is handy to store other identity documents such as loyalty card(s) within the wallet. It also eliminates the need to carry multiple physical cards. Now as we have understood in simple words the meaning of digital wallets let us understand how do digital wallet transactions work. Steps of a digital wallet transaction being performed To use a digital wallet, the user needs to open the wallet application on mobile. To do this users can either use facial recognition, fingerprint identification, or PIN codes (based on the phone model and the configuration) Post unlocking the application, the user next selects the stored payment method for use, as digital wallets allows to store multiple cards There can be two type of transactions for digital wallet...

What is a data diode? A data diode is hardware device that is often called a "unidirectional security gateway". It is placed between two networks with different levels of security and controls the flow of information in a safe, one-way transfer of data between segmented networks. In terms of security, network data flowing through data diodes makes it impossible for an insecure or hostile network to imbibe malware or access the system. Data diodes allows data processing in real time to information management systems protecting valuable information and network infrastructure from theft, destruction, tampering, and human error, mitigating potential loss of thousands of dollars and countless hours of work. Data diode design maintains physical and electrical separation of source and destination networks, establishing a non-routable, completely closed one-way data transfer between networks eliminating external points of entry to the sending system, preventing intruders and contagio...
