IJRET : International Journal of Research in Engineering and Technology is an international peer reviewed, online journal published by eSAT Publishing House for the enhancement of research in various disciplines of Engineering and Technology. The aim and scope of the journal is to provide an academic medium and an important reference for the advancement and dissemination of research results that support high-level learning, teaching and research in the fields of Engineering and Technology. We bring together Scientists, Academician, Field Engineers, Scholars and Students of related fields of Engineering and Technology
Network security is important to protect systems from attacks. Firewalls act as the first line of defense, blocking unauthorized incoming and outgoing network traffic based on security rules. Different types of firewalls operate at different layers of the OSI model and provide varying levels of security. No single security measure can guarantee protection, so a defense-in-depth approach using firewalls along with other tools like intrusion detection systems is recommended.
This document discusses one-time passwords (OTPs) and how they are generated and delivered. It defines a password as a sequence of characters used to verify a user's identity when accessing a system. A secure password contains uppercase and lowercase letters, numbers, and symbols. An OTP is only valid for one login session and helps prevent replay attacks. OTPs are generated using algorithms involving pseudorandomness or randomness. Common methods of OTP generation include time synchronization, mathematical algorithms, and challenges. OTPs are then delivered via text message, websites with image grids, or printed hard copies. In conclusion, OTPs provide security advantages and are widely used for activities like creating accounts and making online payments.

This document discusses authentication methods and focuses on graphical passwords. It begins with an overview of common authentication methods like text passwords, tokens, and biometrics. It then discusses the drawbacks of text passwords and introduces graphical passwords as an alternative. The document surveys recall-based and recognition-based graphical password techniques and provides examples like Draw-A-Secret and Passfaces. It concludes by noting the advantages of graphical passwords in usability and security but also disadvantages like longer login times and storage requirements.
The document discusses ethical hacking and describes hackers. It defines ethical hacking as evaluating a system's security vulnerabilities by attempting to break into computer systems. Ethical hackers possess strong programming and networking skills and detailed hardware/software knowledge. They evaluate systems by determining what intruders can access, what they can do with that information, and if intruder attempts can be detected. The document outlines different types of hackers and classes them as black hats, white hats, gray hats, and ethical hackers based on their motivations and how they use their skills.
This document provides an overview of security and hacking. It defines security as protection from harm and defines differences between security and protection. It then discusses what hacking and hackers are, provides a brief history of hacking from the 1960s to present day, and describes different types of hackers like white hat and black hat hackers. The document also outlines the hacking process and some common tools used. It lists some famous hackers and recent news stories about hacking.
This document provides an overview of hacking, including its history, definitions, types, famous hackers, reasons for hacking, and advice on security and ethics. Hacking emerged in the 1960s at MIT and refers to attempting to gain unauthorized access to computer systems. It describes hackers as those who exploit weaknesses in computers. Different types of hacking are outlined such as website, network, password, and computer hacking. Advice is given around using strong unique passwords, backing up data, and contacting authorities if hacked. Both advantages like security testing and disadvantages like privacy harm are discussed.
