0.2 Understanding accessible experiences

Comment: Web sites are fast becoming something we cannot live without, but it is insecure. User confidence is vital, and it does not matter what the skill, knowledge, experience or ability level a user has, we must develop web sites that are safe to use and do not create additional risks to the user.

Proposed change: In the sentence "The goal of any web project should be to create web experiences that are accessible, usable and enjoyable for everyone." add the word "safe" so that it reads "The goal of any web project should be to create web experiences that are accessible, usable, safe and enjoyable for everyone." This would necessitate an additional column in Table 1

Safe

The user's privacy, data and computer systems are not compromised while they accomplish their goals.

Examples

No malicious code was downloaded while downloading the web content

The user has confidence in the integrity of the information in the video

The audio description and video are available when the user requires

By changing browser settings or the type of user agent, the user should not be at greater risk than other users

5.1 Web technologies

Comment: In the choice of technology, how it is implemented and maintained, and how it interacts with the user, the servers and third-parties should be understood so that the security risks, and hence accessibility issues, are considered during the selection stage.

Proposed change: Add another bullet point "whether the technology could introduce additional security vulnerabilities and how these would be mitigated;"

5.3 The technology selection process

[I feel there should be an additional bullet point here relating to security, but can't think of a suitable one just yet]

Comment: ?

Proposed change: Add another bullet "??????" in "Ensuring your audience will be able to do the following with your web content:" after "understand it;"

6.3 User Agent Accessibility Guidelines (UAAG) --

Comment: While the website should be usable in popular browsers, this is not sufficient for testing purposes. Developers/programmers needs to realise that people will try and access the content using "non-browser" tools to look for vulnerabilities and the website should be secure enough to protect users and itself from such threats. This requires testing beyond "popular browsers".

Proposed change: Add "Note 6 - The website must secure enough to protect itself and its users from security vulnerabilities which may not be apparent by limiting testing to 'a reasonable range of web browsers'. OWASP has produced a detailed testing guide http://www.owasp.org/index.php/Category:OWASP_Testing_Project"

8.2.3.3 Validation --

Comment: Security testing should also be undertaken at the same time.

Proposed change: Add "The Security of the website should be validated by ensuring that vulnerabilities identified in the compliance to OWASP Top 10 are mitigated. A comprehensive testing methodology is published by OWASP as 'OWASP Testing Guide' http://www.owasp.org/index.php/Category:OWASP_Testing_Project"

8.2.3.4 Conformance inspection --

Comment: Undocumented or unwanted functionality can often lead to security vulnerabilities. For a webpage to conform, every aspect must be validated; this requires a full understanding of the webpage and how it interacts with the user, data, servers, etc.

Proposed change: Add to the end of the first paragraphs "All aspects elements within the webpage must be inspected. Thus any undocumented features, functions or security vulnerabilities must also undergo validation testing. undertake a validation test .  The web page site code should be reviewed to ensure no security vulnerabilities exist that may hamper the usage and accessibility. OWASP provides a s very methodical approach to security code review that is available under 'OWASP Code Review Guide' http://www.owasp.org/index.php/Category:OWASP_Code_Review_Project"

8.2.3.6 Expert review -

Comment: Security is an aspect of quality (see ISO 9126)

Proposed change: Add "Quality can not be achieved without ensuring proper security. Security is a quality vector and should be taken into consideration while conducting expert reviews. OWASP experts familiar with methodologies can help review the application from security standpoint and help ensure high quality."

Comment (DC): Are we going out on a limb here offering up free "consultancy" services from "OWASP experts" ?

Annex F - F.1.2 Web developer -

Comment: Security is an aspect of quality (see ISO 9126). Content cannot may not be accessible if there are security vulnerabilities.

Proposed change: Add "It is also important for a web developer to learn secure coding. This will help reduce the risk of security vulnerabilities in the website and provide users with a better usability and accessibility of the content. OWASP has defined best practices for secure coding aided with code snippets and examples that can help developers to learn the art of secure coding."

Annex G - G.2 Criteria for measuring success

Comment: Without validated security, there is no way to ensure that webpages conform to accessibility requirements.

Proposed change: Add as a new bullet point under a) "How well the risk of getting compromised through a security vulnerability is mitigated? (degree of risk vs. usability)" and as a new bullet point under b) "How low is the threat of user’s computer becoming infected through malicious code from the website? (Degree of confidence in the website for efficient utilization)" and as a new bullet point under c) "Perceived security (Peace of mind / trust / reliable and secure user experience)"

Annex H (informative) Contracting web design and auditing services --

Comment: User confidence is vital, and it does not matter what the skill, knowledge, experience or ability level a user has, we must develop web sites that are safe to use and do not create additional risks to the user. Webpages and websites with security vulnerabilities are not accessible unless the vulnerabilities are also validated for conformance.

Proposed changes: In H.1.1 add " In regards to web security, OWASP a globally recognized community has produced tools, specifications and guidelines focusing on best coding practices, security code review, Testing Guide, Code Review and Top 10 vulnerabilities (considered as a de-facto list for most of the compliances such as PCI-DSS, VISA etc). All of OWASP resources are free to use.", In H.1.3 add another item "awareness of website security issues", in H.3.1 add another item "Will security implications be included in the testing?" and in H.3.2 add another item "Does the supplier use the OWASP Application Security Verification Standard (ASVS) to provide a level of confidence in the security of the project"

Comment (DC): VISA compliance? Also is the ASVS release quality yet?

Bibliography - Useful web contents --

Comment: OWASP has the most comprehensive resources available for specifying, designing, developing, testing and operating web applications. For example, the Top 10 project is referenced in the PCI Data Security Standard. http://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project

Proposed change: Add "Open Web Application Security Project (OWASP) http://www.owasp.org"

Draft Text version 1
''The format for providing feedback requires a comment and proposed change. As feedback is provided PER SECTION, we cannot assume anyone will read the feedback to other sections first i.e. each comment/change must stand on its own merits.''

We may also need some generic WHO ARE OWASP text.
