A GENERIC FRAMEWORK FOR DEVICE PAIRING IN UBIQUITOUS COMPUTING ENVIRONMENTSIJNSA Journal
Recently secure device pairing has had significant attention from a wide community of academic as well as industrial researchers and a plethora of schemes and protocols have been proposed, which use various forms of out-of-band exchange to form an association between two unassociated devices. These protocols and schemes have different strengths and weaknesses – often in hardware requirements, strength against various attacks or usability in particular scenarios. From ordinary user’s point of view, the problem then becomes which to choose or which is the best possible scheme in a particular scenario. We advocate that in a world of modern heterogeneous devices and requirements, there is a need for mechanisms that allow automated selection of the best protocols without requiring the user to have an in-depth knowledge of the minutiae of the underlying technologies. Towards this, the main argument forming the basis of this research work is that the integration of a discovery mechanism and several pairing schemes into a single system is more efficient from a usability point of view as well as security point of view in terms of dynamic choice of pairing schemes. In pursuit of this, we have proposed a generic system for secure device pairing by demonstration of physical proximity. The contributions presented in this paper include the design and prototype implementation of the proposed framework along with a novel Co-Location protocol.

Holistic privacy impact assessment framework for video privacy filtering tech...sipij
The document presents a Holistic Privacy Impact Assessment Framework (H-PIA) for evaluating video privacy filtering technologies. The framework is based on the UI-REF normative ethno-methodological framework for Privacy-by-Co-Design. The H-PIA framework integrates key holistic performance indicators (KPIs) comprising objective and subjective evaluation metrics. It assesses the optimal balance of privacy protection and security assurance for privacy filtering solutions negotiated through user-centered co-design. Both objective automated tests and a subjective user study are conducted to evaluate filtering performance based on criteria like efficacy, consistency, disambiguity, and intelligibility. Results confirm the framework enables optimally balanced privacy filtering while retaining necessary information.

This document discusses the security benefits and challenges of virtual desktop infrastructure (VDI). Key points include:
- VDI provides security benefits like centralized execution, zero data at the endpoint, and remote access. However, it does not reduce the overall attack surface or protect against advanced threats.
- While the datacenter is more secure than individual endpoints, VDI desktops are still equally susceptible to zero-day exploits and malware as legacy desktops. Patching and recovery processes are also similar between VDI and physical desktops.
- Some security solutions like client-side hypervisor isolation aim to address these issues by virtualizing vulnerable tasks, but do not fully solve the problem on their own. A layered security approach

This document discusses heuristic evaluation as a usability testing technique. It defines heuristic evaluation as a practical approach to problem solving and discovery that may not be optimal but is sufficient for immediate goals. The document lists Nielsen's 10 usability heuristics for interface design, such as visibility of system status and user control and freedom. It provides examples for each heuristic and advises that heuristic evaluation should not replace talking to users, but can help identify usability issues before user testing.
The document outlines 10 usability heuristics for user interface design: 1) keep users informed of system status, 2) use language familiar to users, 3) allow users easy exit from unwanted states, 4) be consistent in design, 5) prevent errors from occurring, 6) make needed information visible rather than requiring recall, 7) support both inexperienced and experienced users, 8) avoid unnecessary information, 9) help users recognize, diagnose, and recover from errors, and 10) provide help documentation that is easy to use. It also describes a workshop where groups will evaluate examples based on 2 assigned heuristics.
Rolf Molich and Jakob Nielsen developed a set of heuristics for interface design in 1990. In 1994, Nielsen refined these heuristics into 10 key principles: (1) keep users informed of system status, (2) speak the users' language with familiar words, (3) allow easy exit from unwanted states, (4) be consistent in design standards, (5) prevent errors from occurring, (6) make objects and actions visible to minimize memory load, (7) support both inexperienced and experienced users, (8) avoid irrelevant information for clean design, (9) help users recognize, diagnose and recover from errors, and (10) provide help that is easy to search and focused on tasks

The document provides an overview of design process and factors that affect user experience in interface design. It discusses various principles and heuristics to support usability, including learnability, flexibility, and robustness. The document outlines principles that affect these factors, such as predictability, consistency and dialog initiative. It also discusses guidelines for improving usability through user testing and iterative design. The document emphasizes the importance of usability and provides several heuristics and guidelines to measure and improve usability in interface design.
The document summarizes key principles of user interface design from Donald Norman's book "The Design of Everyday Things". It states that well-designed objects are easy to understand and use as they provide visible clues to operation, while poorly designed objects can be difficult and frustrating as they provide no or false clues. The result is a world filled with user frustration.
User Experience Design - Designing for othersBART RADKA
The document discusses user-centered design (UCD). It describes UCD as a multistage process that allows designers to understand how users will interact with a product from the user's perspective. The key stages of UCD are analysis, design, implementation, and deployment. During analysis, user research such as field studies and usability testing is conducted. In the design stage, prototypes are created and tested. Implementation involves working with development teams. Deployment includes gathering user feedback. The goal of UCD is to create products that meet users' needs and are easy to use.
This document provides an overview of interaction design rules and usability requirements. It discusses various types of design rules including principles, standards, heuristics and guidelines. Specific principles are outlined to support usability in terms of learnability, flexibility and robustness. Examples of standards and guidelines are also described. Nielsen's 10 heuristics and Shneiderman's 8 golden rules for interface design are summarized. The document emphasizes the importance of user-centered design and involvement through iterative prototyping and evaluation. Key questions for user-centered design are listed regarding identifying stakeholders and understanding user needs.
This document provides summaries of several guidelines and methods for human-computer interaction (HCI). It discusses Shneiderman's Eight Golden Rules for designing user interfaces, Norman's seven principles of interaction design, Norman's model of the interaction process, Nielsen's ten usability heuristics, contextual inquiry for understanding user needs, and cognitive walkthrough for evaluating design. The summaries focus on key principles for making interfaces easy to use, learn, and remember through consistency, feedback, affordances, mapping to real world concepts, error prevention, and minimizing memory load.
This document provides an overview of intelligent user interfaces and user adaptivity. It discusses how intelligent interfaces can improve human-computer interaction by adapting to individual users based on their characteristics and behaviors. The benefits of adaptive systems include supporting tasks, information finding, and learning. Designing such systems poses usability challenges around transparency and control. Data can be collected explicitly from users or implicitly from their actions. There is a growing need for adaptive systems as technology increases in complexity and scope.
Usability Engineering General guidelinesREHMAT ULLAH
This document discusses general usability guidelines for user interface design. It outlines several key principles: [1] The interface should keep users informed of system status and progress. [2] The interface language and concepts should match the users' language and mental models. [3] Users should feel in control and have freedom within the system to undo or redo actions. [3] Consistency in terminology, actions, and behaviors is important for usability.
Ten Usability Heuristics by Jakob Nielsen.pptxsharmiladevi941
1) The 10 usability heuristics provide guidelines for interface design including visibility of system status, matching the system design to real world concepts, giving users control and freedom, maintaining consistency, preventing errors, using recognition over recall, providing flexibility and efficiency, having an aesthetic and minimal design, helping users recover from errors, and providing helpful documentation.
2) Some key guidelines within the heuristics are to always inform users of the system status, speak the user's language with familiar concepts, clearly label ways to exit tasks, maintain consistency across interfaces, eliminate error-prone conditions, reduce memory demands on users, allow for customization and shortcuts, remove unnecessary elements, and give constructive error messages.

Before spending your budget on Evaluating Interfaces with Users, it's essential to do a evaluation at your end.
At SwitchMe, I took a session with my team of developers to explain importance and method of Evaluating Interfaces at our end first.
Evaluation techniques can be used at all stages of the design process to test interfaces and identify problems. There are two main categories of evaluation: expert analysis and user participation. Expert analysis includes cognitive walkthroughs, heuristic evaluations, and review-based evaluations. User participation evaluations involve testing with users and can be done in laboratories, fields studies, or experiments. A variety of techniques exist within each category to gather both qualitative and quantitative feedback. Choosing an evaluation method depends on factors like the design process stage, desired objectivity, and available resources.
This document provides an overview of intelligent user interfaces and user-adaptive systems. It discusses agents and intelligent agents, different types of agent models, and the benefits of user adaptivity. Specifically, it explains how systems can adapt their behavior and interfaces based on individual user data to improve functions like task assistance and information recommendation. The document also covers challenges regarding usability and data collection, and anticipates a growing need for user-adaptive systems in the future due to increasing user and context diversity.
Unit 7 performing user interface designPreeti Mishra
The document discusses user interface design principles and models. It provides three key principles for user interface design:
1. Place users in control of the interface and allow for flexible, interruptible, and customizable interaction.
2. Reduce users' memory load by minimizing what they need to remember, establishing defaults, and progressively disclosing information.
3. Make the interface consistent across screens, applications, and interaction models to maintain user expectations.
It also describes four models involved in interface design: the user profile model, design model, implementation model, and user's mental model. The role of designers is to reconcile differences across these models.
1. There are three types of design rules: principles, standards, and guidelines. Principles are abstract rules with low authority but high generality. Standards are specific rules with high authority but limited application. Guidelines have lower authority but more general application.
2. Usability principles include learnability, flexibility, and robustness. Learnability principles focus on predictability, synthesizability, familiarity, generalizability, and consistency. Flexibility principles relate to dialogue initiative, multithreading, task migratability, substitutivity, and customizability. Robustness principles involve observability, recoverability, responsiveness, stability, and task conformance.
3. Well-known guidelines and heuristics
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.

2. Heuristic Evaluation
• Goal: Identifying usability problems in existing
systems
• Checking compliance with a set of usability
principles
• Performed individually
• Results will be aggregated
2
3. Heuristic Evaluation
• Freely explore the interface or perform
certain tasks
• You can go through the interface several times
• You should specify:
– The problem
– The heuristic(s)
– The severity
3
4. IT security management (ITSM) tools
• IT security management tools are components
in the design, development, and maintenance
of a secure information technology
infrastructure.
– Examples: network firewall, intrusion detection
system, identity and access management system
• Characteristics of the ITSM environment
– Complex, collaborative, people with different
backgrounds
4
6. 1 – Visibility of activity status
Provide users with awareness about the status of the activity
distributed over time and space, including the other users
involved in the activity, their actions, and distribution of work
between them; rules that govern the activity; tools,
information, and material that are used in the activity; and
progress toward the activity objective. Provide
communication channels for transferring the status of the
activity. While providing awareness is crucial, provide
awareness only about what a user needs to know to complete
his actions.
6
7. 2- History of actions and changes on
artifacts
Allow capturing the history of actions and
changes on tools or other artefacts such as
policies, logs, and communication between
users. Provide a means for searching and
analyzing historical information.
7
8. 3- Flexible representation of
information
Allow changing the representation of
information to suit the target audience and
their current task. Support flexible reports.
Allow tools to change the representation of
their input/output for flexible combination
with other tools.
8
9. 4- Rules and constraints
Promote rules and constraints on ITSM activities, but
provide freedom for users to choose different paths
that respect the constraints. Constraints can be
enforced in multiple layers. For example, a tool could
constrain the possible actions based on the task, the
chosen strategy for performing the task (e.g., the order
of performing actions), the social and organizational
structure (e.g., number of subjects involved in the task,
policies, standards), and the competency of the user.
9
10. 5- Planning and dividing work between
users
Facilitate dividing work between the users involved in
an activity. For routine and pre-determined tasks,
allow incorporation of a workflow. For unknown
conditions, allow generation of new work plans and
incorporation of new users.
10
11. 6- Capturing, sharing, and discovery of
knowledge
Allow users to capture and store their knowledge
explicitly by generating documents, web-pages, scripts,
and notes or implicitly by providing access to a history
of their previous actions. Tools could then facilitate
sharing such knowledge with other users. Furthermore,
tools should facilitate discovery of the required
knowledge source including artefacts or a person who
possess the knowledge and provide means of
communicating with the person who possesses the
knowledge.
11
12. 7- Verification of knowledge
For critical ITSM activities, tools should help SPs validate their
knowledge about the actions that are required to perform the
activity. Allow users to validate their knowledge by
performing actions and validating the results on a test system
before applying them to the real system. Allow users to
document the required actions in the form of a note or a
script; this helps the users or their colleagues to review the
required actions before applying them on the system.
12
14. 1 - Visibility of system status
The system should always keep users informed
about what is going on, through appropriate
feedback within reasonable time.
14
15. 2 - Match between system and the real
world
The system should speak the users' language,
with words, phrases and concepts familiar to the
user, rather than system-oriented terms. It
should follow real-world conventions, making
information appear in a natural and logical
order.
15
16. 3 - User control and freedom
Users often choose system functions by mistake
and will need a clearly marked "emergency exit"
to leave the unwanted state without having to
go through an extended dialogue. Support undo
and redo.
16
17. 4 - Consistency and standards
Users should not have to wonder whether
different words, situations, or actions mean the
same thing. Follow platform conventions and
terminology which are familiar to the user.
17
18. 5 - Error prevention
Even better than good error messages is a
careful design which prevents a problem from
occurring in the first place. Either eliminate
error-prone conditions or check for them and
present users with a confirmation option before
they commit to the action.
18
19. 6 - Recognition rather than recall
Minimize the user's memory load by making
objects, actions, and options visible. The user
should not have to remember information from
one part of the dialogue to another. Instructions
for use of the system should be visible or easily
retrievable whenever appropriate.
19
20. 7 - Flexibility and efficiency of use
Accelerators -- unseen by the novice user -- may
often speed up the interaction for the expert
user such that the system can cater to both
inexperienced and experienced users. Allow
users to tailor frequent actions.
20
21. 8 - Aesthetic and minimalist design
Dialogues should not contain information which
is irrelevant or rarely needed. Every extra unit of
information in a dialogue competes with the
relevant units of information and diminishes
their relative visibility.
21
22. 9 - Help users recognize, diagnose, and
recover from errors
Error messages should be expressed in plain
language (no codes), precisely indicate the
problem, and constructively suggest a solution.
22
23. 10 - Help and documentation
Even though it is better if the system can be
used without documentation, it may be
necessary to provide help and documentation.
Any such information should be easy to search,
focused on the user's task, list concrete steps to
be carried out, and not be too large.

Editor's Notes
The ITSM version
The goal of heuristic evaluation is to identify usability problems in a system. The heuristic evaluation method employs a set of usability principles, called heuristics, to guide the evaluators in identification of usability problems. Each evaluator inspects the interface and checks the compliance of the interface with the heuristics. Heuristic evaluation is performed individually by each evaluator and then the results from different evaluators are aggregated into a set of usability problems.
During heuristic evaluation, you can freely explore an interface and identify problems or you can use scenarios to focus on a specific part of the system. In this study, we will use scenarios to limit the scope of the evaluation. You can walk through the steps of each scenario and perform them on the interface once or multiple times. Also, you are free to explore other parts of the interface to become familiar with the interface. But we are only interested in identifying problems related to the provided scenarios. For each problem that you identify, you should specify 3 components: First, the problem itself. Second, the scenario in which you identified the problem. Third, the heuristic (or heuristics) with which you found the problem. You might find problems that can’t be associated to a heuristic. For those problems, just record the problem, and scenario.
As we are going to evaluate an IT security management tool, I want to give you a quick background about this class of applications. IT security tools are components in the design, development, and maintenance of a secure information technology infrastructure. Tools like network firewalls, intrusion detection systems, and identity and access management systems are examples of IT security management tools. The environment in which these tools work has certain characteristics. First, it is complex. Everyday, new security issues arise in this environment that need to be addressed in a timely fashion. Many tasks of security administrators are not routine, and require knowledge and expertise. Second, this environment is collaborative. It means that different stakeholders in the organization need to collaborate with each other to perform their tasks. Third, the stakeholders involved in IT security management have different background. There are security administrators, managers, employees, and external contractors who need to collaborate with each other to perform IT security management tasks.
Now I will present the heuristics you will be using today. For each heuristic, I will describe it and give an example of how it can be applied to an IT security management tool, in this case, a network firewall. There are 7 heuristics that I will describe. They are called ITSM heuristics. I will go through them in this tutorial and give examples of how they can be applied to IT security tools.
IT security management activities are distributed over time and space and they include multiple users. These users work in an organizational environment and must comply with the rules in the organization (e.g., the security policy, privacy policy, and other organizational rules) and standards. Therefore, the tool should provide the required awareness about the status of the activity, the other users involved, the progress toward activity objectives, rules, available tools, etc., about the activity, to all of the stakeholders of the tool. It is important to only provide the status that users really need to know, not more.
Historical information could be in the form of use-histories by other people or the subject himself. Use histories can be employed to reflect on work and getting feedback from peers. In IT security, reflecting on work is important as the actions are performed on the system by different stakeholders. Moreover, security regulations require the system to keep a history of actions.
As IT security tools have different stakeholders, tools should be able to present information in the format suitable to the target audience. Furthermore, to address complexity, providing different presentation of data allows the user to view information from different perspectives and help them understand complex scenarios. From a different view point, security admins like to combine their tools together to address different problems. Therefore, tools should be able to present their information in a way that can be used by other tools and also accept inputs from different tools.
As ITSM tool designers can’t predict all the conditions that a tool user might face, they should provide freedom for users to choose the way they want to perform the activities. Therefore, while there should be multiple ways for users to perform activities, constraints should be enforced by the tool so the user can only choose those paths that are not violating any of the constraints.
Because the use of ITSM tools involves multiple stakeholders, the tool should provide facilities for dividing work between different stakeholders. For those tasks that have a routine procedure, incorporation of a workflow in the tool would be a good idea. But for unknown conditions, tool should provide ways for users to generate plans for performing the activity (for example, showing who is available to perform a task or allow a workflow to be created dynamically)
To address problems in the complex and evolving environment of ITSM, a subject needs to use the knowledge and experience of other stakeholders involve in the activity. To facilitate accessing distributed knowledge, ITSM tools should enable their users to express their knowledge in a form of a document, web-page, or script that can be used by other users and also facilitate identification and access to the required knowledge sources for accomplishing the activity. In cases that documenting knowledge is not feasible, a method for finding and starting collaboration with the person who possesses the knowledge should be provided.
Many actions in ITSM are responses to new, unseen and complex situations. These actions should be performed on systems that are critical to the organization. Moreover, the actions are distributed in time and space and the result of an action can't be evaluated in real time. Therefore, the cost of errors in these actions is huge. To find a solution to a new or complex problem, a security admins usually consults different information sources and combines them into a single plan (a plan, a guide document, a check list, etc.) This plan extracted from different sources might not be correct. Therefore, it should be verified before applying it to the system. Therefore, ITSM tools should allow users to rehearse the action on a non-critical, test system, evaluate the outcome of the action, and then apply it on the critical system. If something goes wrong in the rehearsal, the user can re-examine his or her interpretation of the external sources. After successful rehearsal, users can perform rehearsed actions on the critical artifact. To facilitate this process, tools should help creation of a non-critical system from a critical system, and help the process of applying rehearsed plan on the critical system.
Now I will present the heuristics you will be using today. For each heuristic, I will describe it and give an example of how it can be applied to an IT security management tool, in this case, a network firewall. There are 7 heuristics that I will describe. They are called ITSM heuristics. I will go through them in this tutorial and give examples of how they can be applied to IT security tools.
The system should keep users informed about what is going on in the system, through appropriate feedback within reasonable time, so that users can accurately determine the right action to perform on the system and also can determine the result of their actions.
Users can understand the system if it matches what the users know from the real world. [Nielsen heuristic itself with modifications] Therefore, the system should speak the users' language, with words, phrases, and concepts familiar to the user, rather than using system-oriented terms. It should follow real-world conventions, making information appear in a natural and logical order.
Users often make mistakes in choosing their actions. Therefore there should be a way for users to exit an undesirable state. Supporting undo or redo is an example of a shortcut for exiting such an unwanted state.
When using a system, users should not have to wonder whether different words, situations, or actions mean the same thing. It is better if the system can follow platform conventions and terminology which are familiar to the user.
Even better than good error messages is a careful design that prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action.
Minimize the user's memory load by making objects, actions, and options visible. The user should not have to remember information from one part of the dialogue to another. Instructions for use of the system should be visible or easily retrievable whenever appropriate.
Different users might use system in different ways. For example a novice user might prefer to go through more steps that help him do the tasks successfully, but an expert user might prefer a very straightforward way for performing an action that he is familiar with. Therefore, it would be good if the tool provides customization in a way that helps users tailor their frequent actions and choose the way they want to perform their tasks.
Dialogues should not contain information which is irrelevant or rarely needed. Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.
Error messages should be expressed in plain language (no codes), precisely indicate the problem, and constructively suggest a solution.
Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused on the user's task, list concrete steps to be carried out, and not be too large.
