User authentication is the process of verifying an identity claimed by a system entity. There are four main means of authenticating a user's identity: something the user knows (e.g. password), something the user possesses (e.g. smart card), something the user is (e.g. fingerprint), and something the user does (e.g. typing rhythm). Password authentication is widely used but vulnerable to dictionary attacks, password guessing, workstation hijacking, and exploiting multiple password use or user mistakes. Techniques like password hashing with salts and account lockouts help strengthen password authentication against cracking attempts.

Authentication and session v4
Authentication and session management are important aspects of network security. Authentication verifies a user's identity, while session management maintains user access after authentication. Common authentication methods include passwords, multifactor authentication, and digital signatures. Session management uses session IDs and cookies to track authenticated users and can be vulnerable to hijacking attacks. Developers should implement standard security practices like encryption, complex passwords, and short session timeouts to strengthen authentication and prevent session threats.

IRJET- Honeywords: A New Approach for Enhancing Security
This document summarizes a research paper on honeywords, a new approach for enhancing password security. Honeywords involve storing fake passwords (honeywords) along with the real password for each user account. If an attacker tries to login with a honeyword, it triggers an alarm. The document outlines the proposed system, which generates a unique honey index for each account during registration. It stores the hash of the real password along with the correct honey index. If an attacker enters an incorrect password after 3 attempts, the account is blocked. The system creates honeywords after successful login. It also discusses related work and concludes that honeywords make password cracking detectable and more difficult.

Unit-4-User-Authentication.pptx
User authentication is the process of verifying a user's identity before granting access to a system or network. There are several important principles to consider, including using strong passwords, two-factor authentication, least privilege access, secure password storage, regular password updates, and access logs. Following these principles helps ensure security and prevent unauthorized access.

This document discusses securing database passwords. It begins by outlining some challenges with storing passwords in plain text or encrypted form, namely that anyone with access could gain passwords. It then discusses encrypting passwords as more secure but still having issues if the secret is compromised or two users share the same encrypted password. It introduces using a salt to help address known plaintext attacks, and concludes discussing using a hash function and salt to better secure passwords.
Solving problems with authentication
Solving Problems with Authentication discusses common authentication attacks and issues with passwords. It notes that passwords are inherently insecure due to susceptibility to brute force attacks and human error. While services have implemented measures like multifactor authentication and minimum password requirements, these solutions can be complex, costly, and disruptive. The document recommends removing passwords and using alternative authentication methods like biometric authentication and physical security keys. It also suggests decentralizing authentication and allowing multiple login options to improve security without reducing usability.
A Novel Web-based Approach for Balancing Usability and Security Requirements ...
This document describes a novel web-based framework called iPass that aims to balance usability and security requirements for text passwords. The framework educates users on password strength, monitors entered passwords for strength, and provides feedback to help users select stronger passwords that meet usability needs. It was developed to address the conflicting goals of users wanting easy passwords and services requiring strong security. The framework suggests transformed versions of entered passwords or allows user selection from options to improve strength while considering memorability.
finale.ppt.pptx
This document describes a graphical password authentication system project. The project aims to create a more secure authentication method than traditional text passwords by using images and click points. It will have hardware and software requirements and address problems with standard passwords like dictionary attacks. The objectives are to understand human memory for visual information and have users click points on an image as their password. It will provide security advantages over text passwords and be more user-friendly.
MOBILE & WIRELESS SECURITY And MOBILE & WIRELESS SECURITY
This document provides an overview of mobile and wireless security. It discusses the need for security as wireless networks become more prevalent and outlines some common security threats like spoofing, sniffing, tampering and theft. It then describes various security technologies used to address these threats, including cryptography, digital certificates, digital signatures and public key infrastructure. Specific security protocols like SSL, TLS and IPSec are also mentioned. The document emphasizes that securing wireless networks requires considering authentication, data integrity, confidentiality, authorization and non-repudiation across the entire environment.
E0962833

Based on the information provided, it is difficult to definitively say which risk is "bigger" without more context about the system and environment. Some factors to consider when comparing risks include:
- Likelihood of occurrence
- Potential impact of an exploit
- Existing controls and their effectiveness
- Cost to address
A structured approach like assigning ratings (e.g. high, medium, low) across these dimensions can help to systematically compare risks. Ultimately, the organization's priorities and risk tolerance also influence which risks should be addressed first. Regular re-evaluation is important as the environment changes over time. Addressing the highest priority risks based on a well-defined analysis process helps to strengthen security in a cost-effective manner.
CHAPTER 7 Authentication and Authorization On
CHAPTER
7
Authentication and
Authorization
One of the most common ways to control access to computer systems is to
identify who is at the keyboard (and prove that identity), and then decide what
they are allowed to do. These twin controls, authentication and authorization,
respectively, ensure that authorized users get access to the appropriate
computing resources, while blocking access to unauthorized users.
Authentication is the means of verifying who a person (or process) is, while
authorization determines what they’re allowed to do. This should always be done
in accordance with the principle of least privilege—giving each person only the
amount of access they require to be effective in their job function, and no more.
Authentication
Authentication is the process by which people prove they are who they say they
are. It’s composed of two parts: a public statement of identity (usually in the form
of a username) combined with a private response to a challenge (such as
a password). The secret response to the authentication challenge can be based on
one or more factors—something you know (a secret word, number, or passphrase
for example), something you have (such as a smartcard, ID tag, or code
generator), or something you are (like a biometric factor like a fingerprint or
retinal print). A password by itself, which is a means of identifying yourself
through something only you should know (and today’s most common form of
challenge response), is an example of single-factor authentication. This is not
considered to be a strong authentication method, because a password can be
intercepted or stolen in a variety of ways—for example, passwords are frequently
written down or shared with others, they can be captured from the system or the
network, and they are often weak and easy to guess.
Imagine if you could only identify your friends by being handed a previously
agreed secret phrase on a piece of paper instead of by looking at them or hearing
their voice. How reliable would that be? This type of identification is often
portrayed in spy movies, where a secret agent uses a password to impersonate
someone the victim is supposed to meet but has never seen. This trick works
precisely because it is so fallible—the password is the only means of identifying
the individual. Passwords are just not a good way of authenticating someone.
Unfortunately, password-based authentication was the easiest type to implement
in the early days of computing, and the model has persisted to this day.
Other single-factor authentication methods are better than passwords. Tokens
and smart cards are better than passwords because they must be in the physical
possession of the user. Biometrics, which use a sensor or scanner to identify
unique features of individual body parts, are better than passwords because they
can’t be shared—the user must be present to log in. However, there are ways to
defeat these methods. Tokens and card ...
Addressing Insider Threat using "Where You Are" as Fourth Factor Authentication
This document proposes using location as a fourth factor for authentication in addition to the traditional three factors of what you know, what you have, and what you are. It aims to address limitations of current authentication techniques for dealing with insider threats. Specifically, current methods do not provide continuous identification tracking or allow for real-time enforcement of security policies. The document outlines general rules an authentication system should follow, including not hindering users or violating physical laws. It argues that using accurate location tracking from real-time locating systems could satisfy the rules by providing continuous authentication without inconveniencing users. The document then discusses requirements for an insider threat prevention system that would actively monitor for malicious insider behavior using location as the fourth authentication factor.
Encryption During Communication
This document discusses encryption and secure communication. It explains that encryption encodes messages using algorithms and keys so that only authorized parties can decode it, preventing unauthorized access. The two main types of encryption algorithms are symmetric, for sending information, and asymmetric, for sending both information and keys. Standards like ISO/IEC 27001 provide requirements for establishing and maintaining an effective information security management system to address risks through controls like encryption. PECB offers training and certification services related to ISO standards to help organizations securely implement management systems.

Investigating the Combination of Text and Graphical Passwords for a more secu...
Security has been an issue from the inception of computer systems and experts have related security issues with usability. Secured systems must be usable to maintain intended security. Password Authentication Systems have either been usable and not secure, or secure and not usable. Increasing either tends to complicate the other.
Text passwords are widely used but suffer from poor usability, reducing its security. Graphical Passwords, while usable, does not seem to have the security necessary to replace text passwords. Attempts using text or graphics only have mixed results. A combination password is proposed as a potential solution to the problem.
This paper explores combination as a means of solving this password problem. We implemented three password systems: Text only, Graphics only and a Combination of Text and Graphics. Remote evaluations were conducted with 105 computer science students. Results from our evaluations, though not conclusive, suggest promise for combination passwords.
Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

This document describes a graphical password authentication system project. The project aims to create a more secure authentication method than traditional text passwords by using images and click points. It will have hardware and software requirements and address problems with standard passwords like dictionary attacks. The objectives are to understand human memory for visual information and have users click points on an image as their password. It will provide security advantages over text passwords and be more user-friendly.
MOBILE & WIRELESS SECURITY And MOBILE & WIRELESS SECURITY
This document provides an overview of mobile and wireless security. It discusses the need for security as wireless networks become more prevalent and outlines some common security threats like spoofing, sniffing, tampering and theft. It then describes various security technologies used to address these threats, including cryptography, digital certificates, digital signatures and public key infrastructure. Specific security protocols like SSL, TLS and IPSec are also mentioned. The document emphasizes that securing wireless networks requires considering authentication, data integrity, confidentiality, authorization and non-repudiation across the entire environment.

Based on the information provided, it is difficult to definitively say which risk is "bigger" without more context about the system and environment. Some factors to consider when comparing risks include:
- Likelihood of occurrence
- Potential impact of an exploit
- Existing controls and their effectiveness
- Cost to address
A structured approach like assigning ratings (e.g. high, medium, low) across these dimensions can help to systematically compare risks. Ultimately, the organization's priorities and risk tolerance also influence which risks should be addressed first. Regular re-evaluation is important as the environment changes over time. Addressing the highest priority risks based on a well-defined analysis process helps to strengthen security in a cost-effective manner.
CHAPTER 7 Authentication and Authorization On
CHAPTER
7
Authentication and
Authorization
One of the most common ways to control access to computer systems is to
identify who is at the keyboard (and prove that identity), and then decide what
they are allowed to do. These twin controls, authentication and authorization,
respectively, ensure that authorized users get access to the appropriate
computing resources, while blocking access to unauthorized users.
Authentication is the means of verifying who a person (or process) is, while
authorization determines what they’re allowed to do. This should always be done
in accordance with the principle of least privilege—giving each person only the
amount of access they require to be effective in their job function, and no more.
Authentication
Authentication is the process by which people prove they are who they say they
are. It’s composed of two parts: a public statement of identity (usually in the form
of a username) combined with a private response to a challenge (such as
a password). The secret response to the authentication challenge can be based on
one or more factors—something you know (a secret word, number, or passphrase
for example), something you have (such as a smartcard, ID tag, or code
generator), or something you are (like a biometric factor like a fingerprint or
retinal print). A password by itself, which is a means of identifying yourself
through something only you should know (and today’s most common form of
challenge response), is an example of single-factor authentication. This is not
considered to be a strong authentication method, because a password can be
intercepted or stolen in a variety of ways—for example, passwords are frequently
written down or shared with others, they can be captured from the system or the
network, and they are often weak and easy to guess.
Imagine if you could only identify your friends by being handed a previously
agreed secret phrase on a piece of paper instead of by looking at them or hearing
their voice. How reliable would that be? This type of identification is often
portrayed in spy movies, where a secret agent uses a password to impersonate
someone the victim is supposed to meet but has never seen. This trick works
precisely because it is so fallible—the password is the only means of identifying
the individual. Passwords are just not a good way of authenticating someone.
Unfortunately, password-based authentication was the easiest type to implement
in the early days of computing, and the model has persisted to this day.
Other single-factor authentication methods are better than passwords. Tokens
and smart cards are better than passwords because they must be in the physical
possession of the user. Biometrics, which use a sensor or scanner to identify
unique features of individual body parts, are better than passwords because they
can’t be shared—the user must be present to log in. However, there are ways to
defeat these methods. Tokens and card ...
Addressing Insider Threat using "Where You Are" as Fourth Factor Authentication
This document proposes using location as a fourth factor for authentication in addition to the traditional three factors of what you know, what you have, and what you are. It aims to address limitations of current authentication techniques for dealing with insider threats. Specifically, current methods do not provide continuous identification tracking or allow for real-time enforcement of security policies. The document outlines general rules an authentication system should follow, including not hindering users or violating physical laws. It argues that using accurate location tracking from real-time locating systems could satisfy the rules by providing continuous authentication without inconveniencing users. The document then discusses requirements for an insider threat prevention system that would actively monitor for malicious insider behavior using location as the fourth authentication factor.
Encryption During Communication
This document discusses encryption and secure communication. It explains that encryption encodes messages using algorithms and keys so that only authorized parties can decode it, preventing unauthorized access. The two main types of encryption algorithms are symmetric, for sending information, and asymmetric, for sending both information and keys. Standards like ISO/IEC 27001 provide requirements for establishing and maintaining an effective information security management system to address risks through controls like encryption. PECB offers training and certification services related to ISO standards to help organizations securely implement management systems.

Investigating the Combination of Text and Graphical Passwords for a more secu...
Security has been an issue from the inception of computer systems and experts have related security issues with usability. Secured systems must be usable to maintain intended security. Password Authentication Systems have either been usable and not secure, or secure and not usable. Increasing either tends to complicate the other.
Text passwords are widely used but suffer from poor usability, reducing its security. Graphical Passwords, while usable, does not seem to have the security necessary to replace text passwords. Attempts using text or graphics only have mixed results. A combination password is proposed as a potential solution to the problem.
This paper explores combination as a means of solving this password problem. We implemented three password systems: Text only, Graphics only and a Combination of Text and Graphics. Remote evaluations were conducted with 105 computer science students. Results from our evaluations, though not conclusive, suggest promise for combination passwords.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Guidelines For Ethical Nudging In Password Authentication
- 1. Guidelines For Ethical Nudging In Password Authentication Presented by: S.M.Nurnobi ID NO: 170103020022
- 2. Abstract Nudging has been adopted by many disciplines in the last decade in order to achieve behavioral change. Information security is no exception. A number of attempts have been made to nudge end-users towards stronger passwords. Here we report on our deployment of an enriched nudge displayed to participants on the system enrolment page when a password has to be chosen.
- 3. Preamble The password is intended to be a secret shared exclusively between the password owner and the system the password controls access .Passwords can leak for a number of reasons. They could be guessed, for example, especially if weak passwords are chosen, as users tend to do Leaked passwords permit unauthorized access to sensitive personal or organizational data in a way that is sometimes very hard to detect.
- 4. Password Expiry Alternatives • Notifications. • Alerts. • Multi-Password. • Multi-Factor. • Multi-Channel. • One-Time Passwords. • Expire Intelligently.
- 5. • The aim of the investigation was to develop an intervention that was powerful enough to induce people to create stronger passwords. • We implemented a strength-dependent password expiry scheme.
- 6. Enriched Nudge Nudge Figure : The Nudge
- 7. Figure : The Incentive Incentive
- 8. Reminder Figure : The Reminder
