On the Internet, the characteristics of ActiveX plug-in software are: general software needs users to download and install separately, while ActiveX plug-in can be automatically downloaded and prompted to install by IE browser when users browse to a specific webpage. A prerequisite for installing ActiveX plug-ins is that they must be approved and confirmed by users.
ActiveX plug-in technology is a common software technology based on Windows platform in the world. Apart from the real-name plug-in of network, many softwares are developed in this way, such as Flash animation player plug-in, Microsoft MediaPlayer plug-in and CNNIC universal website plug-in.
how can browsers ensure the security of ActiveX plug-ins?
When distributing software through the Internet, the security of software is a very noticeable problem. IE browser ensures the security of ActiveX plug-ins in the following ways:
ActiveX uses two complementary strategies: security level and certification to pursue further software security;
Microsoft provides a set of tools that can be used to increase the security of ActiveX objects;
With Microsoft's verification code tool, you can sign an ActiveX control, which tells users that you are indeed the author of the control and that no one else has tampered with it;
in order to use the verification code tool to sign components, you must obtain a digital certificate from a certificate authority; A certificate contains information indicating that a specific software program is genuine, which ensures that other programs can no longer use the logo of the original program. The certificate also records the date of issuance. When you try to download the software, Internet Explorer verifies the information in the certificate and whether the current date is before the expiration date of the certificate. If the information is not up-to-date and valid at the time of downloading, Internet Explorer will display a warning;
in the default security level of IE, before installing ActiveX controls, users can choose whether to continue installing and running the software according to their trust in the software publisher and the software itself.
The network real-name plug-in is signed by the digital certificate issued by Verisign, an international authoritative security manufacturer, so it can ensure the authenticity and security of the network real-name plug-in.
If you want to delete the installed ActiveX plug-ins, you can install a windows Optimizer, which has related functions, and you can choose which ActiveX plug-ins you don't want to install, such as 3721, China Post and other annoying ActiveX plug-ins.
