Mitigation Strategies Analysis for jverdi/jvfloatlabeledtextfield

Mitigation Strategy: Accessibility Compliance (Direct JVFloatLabeledTextField Handling)

1. Mitigation Strategy: Accessibility Compliance (Direct JVFloatLabeledTextField Handling)

   • Description:

     1. Initial Setup:
        • When initializing the JVFloatLabeledTextField instance, directly set its accessibilityLabel property. This provides the primary description for screen readers. Example (Swift):

          let emailField = JVFloatLabeledTextField()
          emailField.accessibilityLabel = "Email Address"

        • Set the accessibilityHint property on the JVFloatLabeledTextField to provide additional context, if necessary. Example:

          emailField.accessibilityHint = "Enter your registered email address"

     2. Dynamic Updates:
        • If the floating label's text (the title property of JVFloatLabeledTextField) changes dynamically to display an error message, immediately update the accessibilityLabel of the same JVFloatLabeledTextField instance to reflect the error. Example:

          if emailField.text?.isValidEmail() == false {
              emailField.title = "Invalid Email" // Assuming you modify the title
              emailField.accessibilityLabel = "Email Address - Invalid format"
          }

        • Consider using UIAccessibility.post(notification:argument:) with .announcement in conjunction with the JVFloatLabeledTextField, to ensure the error is clearly announced. This is related to the component, as it's triggered by the component's state.

   • List of Threats Mitigated:

     • Information Disclosure (Indirect, Component-Specific): (Severity: Medium) - Prevents screen readers from misinterpreting the JVFloatLabeledTextField due to incorrect or missing accessibility information, specifically related to the dynamic floating label.
     • Accessibility Violations (Component Level): (Severity: Low, but legally important) - Ensures the JVFloatLabeledTextField component itself is accessible, contributing to overall application accessibility.

   • Impact:

     • Information Disclosure: Risk significantly reduced for this specific component. Screen reader users get accurate information about the JVFloatLabeledTextField's state.
     • Accessibility Violations: Risk related to the JVFloatLabeledTextField is eliminated (assuming thorough implementation).

   • Currently Implemented:

     • accessibilityLabel is set during initialization in UserProfileViewController.swift and RegistrationViewController.swift for the JVFloatLabeledTextField instances.
     • No dynamic updates to the JVFloatLabeledTextField's accessibilityLabel are performed.

   • Missing Implementation:

     • Dynamic updates to the accessibilityLabel of the JVFloatLabeledTextField instances are missing in all view controllers.

Mitigation Strategy: Secure Labeling (Direct JVFloatLabeledTextField Properties)

2. Mitigation Strategy: Secure Labeling (Direct JVFloatLabeledTextField Properties)

   • Description:

     1. Clear placeholder and title:
        • When creating the JVFloatLabeledTextField, set its placeholder and title properties to text that clearly and unambiguously describes the expected input. These are the direct properties of the component that control its visual labeling. Example:

          let firstNameField = JVFloatLabeledTextField()
          firstNameField.placeholder = "First Name"
          firstNameField.title = "First Name" // Floating label text

     2. Avoid Sensitive Terms in placeholder and title:
        • Do not use terms like "Password," "PIN," etc., in the placeholder or title properties of the JVFloatLabeledTextField unless the field is absolutely intended for that sensitive data. This directly controls what the user sees as the label.

   • List of Threats Mitigated:

     • Phishing (Indirect, Component-Specific): (Severity: Medium) - Reduces the risk of the JVFloatLabeledTextField itself being used to mislead users due to its displayed labels.
     • User Error (Component Level): (Severity: Low) - Helps prevent users from entering the wrong data into the JVFloatLabeledTextField due to unclear labeling on the component itself.

   • Impact:

     • Phishing: Risk reduced by ensuring the JVFloatLabeledTextField's own labels are not misleading.
     • User Error: Risk reduced at the component level by providing clear labels directly on the JVFloatLabeledTextField.

   • Currently Implemented:

     • Most JVFloatLabeledTextField instances have reasonably clear placeholder and title values.
     • No specific documented check to ensure sensitive terms are avoided in the JVFloatLabeledTextField's properties.

   • Missing Implementation:

     • A review of all JVFloatLabeledTextField instances to ensure their placeholder and title properties are unambiguous and avoid sensitive terms is needed.

Mitigation Strategy: Careful Customization and Testing (of JVFloatLabeledTextField)

3. Mitigation Strategy: Careful Customization and Testing (of JVFloatLabeledTextField)

   • Description:

     1. Minimize Customizations:
        • If you customize the appearance or behavior of JVFloatLabeledTextField (beyond basic properties like placeholder and title), keep those customizations as minimal as possible. The more you deviate from the default, the higher the risk of introducing issues.
     2. Thorough Testing:
        • Specifically test any customizations made to the JVFloatLabeledTextField. This includes visual testing, functional testing, and performance testing. Focus on how your changes affect the component's behavior.
     3. Code Review:
        • Have another developer review any code that customizes the JVFloatLabeledTextField, looking for potential errors or unintended side effects.

   • List of Threats Mitigated:

     • Unexpected Component Behavior: (Severity: Variable, potentially Medium) - Reduces the risk of customizations introducing bugs or unexpected behavior in the JVFloatLabeledTextField itself.
     • Performance Issues (Component-Specific): (Severity: Low to Medium) - Helps identify and prevent performance problems caused by customizations to the JVFloatLabeledTextField.

   • Impact:

     • Unexpected Component Behavior: Risk reduced by careful coding and testing of customizations.
     • Performance Issues: Risk reduced by identifying and addressing performance bottlenecks related to the customized component.

   • Currently Implemented:

     • Basic customizations (e.g., font, color) are used in some view controllers.
     • No specific, documented testing procedure focuses on JVFloatLabeledTextField customizations.
     • No formal code review process specifically targets JVFloatLabeledTextField customizations.

   • Missing Implementation:

     • A dedicated testing plan for JVFloatLabeledTextField customizations is missing.
     • A formal code review process for these customizations is missing.
