Accessibility services are essential for many people to use an application. Security policy should not remove that legitimate access through a blanket blocking rule.
Evaluation approach
Distinguish the presence of a service from the risk that it controls a sensitive operation. Examine platform signals and the application workflow together.
Application example
Test payment confirmation with a screen reader on a real device. The security warning itself also needs to be accessible.
Limits and considerations
A policy that forces every accessibility service to be disabled can exclude legitimate users.
Separate accessibility from abuse
A person using a screen reader or assistive input tool should not be classified as risky solely because the service is enabled. Investigate the detection product's observation and its effect on the particular sensitive flow.
Testing should extend beyond a security researcher's device to actual assistive-technology workflows. Focus order, error messages and additional verification steps must remain usable. Tightening policy without monitoring which user groups experience false blocks can damage access.
Checks and decisions
- Test with assistive technology
- Define risky behavior
- Offer alternative verification
Assess risky behavior separately from the use of assistive technology.
