Hacking is a typical method for breaching personal and confidential information. As a result, hacking is also known as infiltration. Intrusions, on the other hand, were not always recognized as theft and were employed for productive purposes. A person or corporation that does ethical hacking and receives incentives from a network or system owner for testing can enter an apparatus (system or network) to locate, repair, and expose network flaws. Most ethical hackers, also known as black hat hackers, test systems using different approaches, methodologies, and tools. Because today's life is lived in a digital world, we need to protect our privacy from cyber-attacks. The proposed paper discussed ethical hacking and its ramifications, in which black hackers "hack" networks. The proposed research emphasizes ethical hacking tactics. This research also examines the impact of ethical hacking on business, education, health, society, the workplace, technology, sensitive information, and human life. Finally, a brief survey based on certain questions is better to grasp the public's understanding of ethical hacking. In summary, this research offers the user fascinating and helpful information when working on ethical hacking.

The potential of information technology has influenced the efficiency and quality of healthcare worldwide. Currently, several republics are incorporating electronic health records (EHRs). Due to reluctance of technological adaptation & implementational complexities, electronic health record systems are not in practice. Due to the emphasis on achieving general compatibility, users may perceive systems as being imposed and providing insufficient customizability, which may exacerbate issues in a setting of national implementation. EHS improves patient safety and confidentiality and ensures operative, effective, well-timed, reasonable, and patient-centred care, all of which substantially impact healthcare quality. Blockchain technology has been used by the EHS system, which supports web-based accessibility and availability. The difficulties of exchanging medical data can now be overcome by consumers using an infrastructure based on cloud computing. A variety of cryptographic approaches have been employed to encrypt and safeguard the data. This review paper aims to highlight the role and impact of blockchain in EHR. The proposed research describes cryptography methods, their classifications, and the challenges associated with EHR to identify gaps and countermeasures.

Cognitive Radio is artificially intelligent radio. This research paper work presents an application of Cognitive Radio and Dynamic Spectrum Access with the help of fuzzy logic considering the inputs: radio and satellite frequency and outputs: adjust power and modulation. This research paper shows the real approach of comparing the simulation and design algorithm result and its successful use.
