It is recommended that users continually stay informed and adaptable to foster a safe browsing experience for all.
What is ActiveX?
ActiveX is a software framework created by Microsoft that allows applications to share functionality and services across different platforms, especially within web browsers. ActiveX controls are reusable components that can be embedded in webpages, enabling enhanced interactivity and user experiences. While primarily associated with Internet Explorer, ActiveX can be utilized across various applications that support it, making it a versatile tool for developers.
However, due to its deep integration with the Windows operating system, ActiveX can pose significant security risks. Malicious users can exploit ActiveX controls, leading to unauthorized actions on the user’s machine or even unauthorized access to sensitive data. As a result, organizations and individuals must carefully evaluate the use of ActiveX in their applications and environments.
What are the main security risks associated with ActiveX?
The primary security risks associated with ActiveX revolve around its ability to execute code on a user’s machine.
