Google Chrome has enhanced user data security by enabling the hardware-mandatory stack protection technology first adopted on Windows 10 last year. Enhanced security on the browser can help limit attackers from exploiting security bugs on the system. The hardware-enhanced stack protection technology can be used with computers based on Windows 20H1 (December Update) or later, and can be used on processors with Control Flow Enforcement Technology (CET) (such as AMD Zen 3 Ryzen and the 11th generation Intel CPU). It is also part of Chrome 90, the browser version that Google released last month.

Although Google Chrome already has a multi-process architecture that reduces the severity of errors, stack protection aims to further enhance security by using CET chip security extensions. This enables the CPU to maintain the shadow stack and the existing stack, which cannot be directly manipulated by ordinary program code.

Stack protection technology is designed to provide security protection to prevent the use of development technologies such as return-oriented programming (ROP) and jump-oriented programming (JOP). Attackers often use these two techniques to access the system by executing malicious code through the browser. This technique may allow attackers to execute a small part of their code, but is designed to prevent them from trying to run malicious code completely.

That being said, Google does admit that in some cases stack protection can be bypassed. Therefore, it is working hard to introduce another Windows-centric technology called Control Flow Guard (CFG), which further reduces the scope of use by attackers.

If your Windows 10 system has a CET-compatible CPU, you can check whether Chrome is using hardware enforcement protection through Windows Task Manager.It can be viewed in the following ways detail > Select column And enable Hardware forced stack protection Options in the task manager application.

Similar to Google’s efforts, Microsoft in February activated Support for Intel CET in Edge 90 (Canary). Mozilla is also committed to enabling CET support to provide the same hardware protection on its Firefox browser.
