Zero Trust Network Access (ZTNA) is an information technology security solution that enables organisations to give safe remote access to their applications, data, and services based on clearly defined access control criteria. ZTNA is distinct from virtual private networks (VPNs) in that it provides exclusive access to certain services or apps, whereas VPNs provide access to the whole network. As more users access resources from their homes or other locations, ZTNA solutions can assist in closing gaps in existing secure remote access technologies and approaches. How does ZTNA function? When ZTNA is used, particular apps or resources are only accessible…

Firmware is special software embedded directly into the hardware. It runs independently of APIs, operating systems, or device drivers, giving instructions and guidance for the device to interface with other devices or execute fundamental activities and functions. Without firmware, even the most straightforward gadgets would fail to work. That is why information is frequently kept on a Read-Only Memory (ROM) chip, ensuring it is not accidentally wiped while being close to the device’s metal. Initially, engineers wrote the firmware only on ROM chips, which made it inexpensive to make and ensured that it was not erased or tampered with. Additionally,…

Web Scraping / Web Harvesting is the method of extracting material and data from a website using bots. Web scraping is a way of obtaining vast volumes of data from websites in an automated fashion. Most of the data is unstructured HTML data that is then transformed into structured data in a spreadsheet or database for usage in various applications. There are several methods for extracting data from websites via web scraping. These options include utilising internet services, specific APIs, or writing your web scraping programs from scratch. Numerous large websites, such as Google, Twitter, Facebook, and Stack Overflow, have…

Parallel computing breaks down more significant problems into smaller, independent, frequently comparable components that may be processed concurrently by several processors communicating via shared memory and then merged as an overall method. Parallel computing’s fundamental objective is to enhance available compute capacity to accelerate application processing and issue resolution. Parallel computing infrastructure is often housed in a single datacentre and consists of numerous processors arranged in a server rack; calculation requests are allocated in tiny pieces by the application server and then completed concurrently on each server. Fig.1. Parallel Processing Parallel computing may be classified into four forms accessible from…

An access control list (ACL) is a collection of rules that specify who can access specific digital environments. ACLs are classified into two types: Filesystem ACLs control access to files and directories. Filesystem ACLs inform operating systems about which users can access the system and what rights they are granted.Networking ACLs control access to the network. ACLs in networking inform routers and switches about the types of traffic that can access the network and the permitted activities. Initially, ACLs were the sole means to defend a firewall. There are several types of firewalls and ACL solutions available today. On the…

This blog will discuss Hierarchical Network Architecture. You will understand the Cisco hierarchical model’s three tiers and how they are employed in network architecture. Network design begins with an analysis of the network component; it is beneficial to classify networks based on the number of devices served: A small network supports up to 200 devices.A medium network supports between 200 and 1000 devices.The extensive network supports over 1000 devices. Network architectures differ according to an organisation’s size and requirements. An extensive company network typically comprises a central campus connecting small, medium, and significant locations. This section will discuss generally established…

The first section of this blog discusses what VLAN is and how it works: the benefits, kinds, and use of VLANs in a multiple switched environment. The partition of large broadcast domains into smaller domains is one method that contributes to network performance improvement. Routers prohibit broadcast traffic on an interface due to a design constraint. On the other hand, Routers often have a restricted number of LAN ports. A router’s primary job is transporting data across networks, whereas granting access to a LAN is often kept for access layer switches. Like Layer 3 devices, users can form a virtual…

Monolithic Architecture Monolithic architectures consist of closely connected processes that run as a single service. If demand for a single method of the application increases, creators must scale the architecture. Adding or upgrading the functionalities of a monolithic program gets increasingly difficult as the code base expands, restricting experimentation and making new ideas harder to execute. Monolithic designs enhance application availability by increasing the effect of a single process failure. To begin, let us compare microservices design to monolithic architecture. A monolithic application is composed entirely of code. Enterprise apps are composed of three distinct components: A database is a…

Blockchain technology, as a stimulus for software development, has gained interest in a variety of businesses worldwide. The following are some prominent features of blockchain technology: autonomy, data auditing, asset tokenization, immutability, transparency, and, most importantly, decentralization. Although blockchain technology benefits the technical world in several ways, it currently lacks scalability, resulting in delays when businesses or start-ups consider using blockchain technology. Blockchain is a decentralized ledger technology that focuses on decentralized transaction management. With decentralized transaction management, each node can begin a transaction autonomously, in accordance with the terms specified by a smart contract, without the intervention of a…

Introduction Application security refers to security measures used at the application level to prevent data or code theft or hijacking. It includes security considerations taken during application development and design, as well as strategies and procedures for safeguarding deployed applications. What is the definition of application security? Application security, abbreviated AppSec, encompasses all duties that help development teams implement a secure software development life cycle. Its goal is to enhance security practises and, as a consequence, to detect, rectify, and, ideally, to avoid application security issues. It includes the requirements analysis, design, implementation, testing, and maintenance phases of an application.…
