Why Is it Impossible for Online Websites to Know Details About Your System and Hardware, or Security Status?

Online websites, in most cases, cannot directly access detailed information about your system, hardware, or security status due to various limitations and security measures in place. Here are some reasons why:

• Browser sandboxing: Modern web browsers operate in a sandboxed environment, which restricts websites from accessing sensitive information or interacting with the underlying system. This isolation ensures that websites can only interact with the browser and its designated resources, preventing direct access to system-level details.
• Security and privacy protocols: To protect user privacy and prevent unauthorized data access, browsers implement security protocols such as the Same Origin Policy and Cross-Origin Resource Sharing. These protocols restrict the ability of websites to access data from other domains or retrieve sensitive information without explicit user consent.
• Limited client-side access: Web technologies like JavaScript have limitations on accessing certain client-side information. Browsers enforce restrictions on accessing hardware-specific details or system-level information to prevent potential security risks and protect user privacy.
• User consent requirements: Websites typically require user consent to access specific information or request permissions for certain actions. For example, accessing geolocation, camera, or microphone requires explicit user permission through browser prompts. This helps ensure that users have control over which websites can access their data or device capabilities.
• Security measures and firewalls: Firewalls and security software on user devices act as a barrier between the internet and the system, preventing unauthorized access and protecting sensitive information. These measures prevent websites from directly accessing system details or security status.
• Privacy-focused browser settings: Users can configure their browser settings to enhance privacy and restrict information sharing. Features like "Do Not Track," cookie settings, and browser extensions can limit the data websites can collect, including system-related details.
