Could merely visiting a web site push a root CA as trusted onto my PC?

If you are an IT administrator, you may be concerned about the security of your computer systems and the data they contain. As such, you may be wondering if merely visiting a website can push a root certificate authority (CA) as trusted onto your computer. The short answer is yes, it is possible, but there are steps you can take to protect yourself.

When you visit a website, the server may push a root certificate authority (CA) to your computer. This certificate authority is a trusted third party that is used to verify the authenticity of the website you are visiting. If a malicious website pushes a root CA onto your computer, it can be used to intercept and decrypt data sent to that website. This could result in a data breach, as the malicious website will have access to sensitive information such as login credentials and financial data.

To protect your computer from malicious websites pushing root CAs onto it, you should make sure that you have updated your computer’s security settings. This includes installing the latest security patches and enabling a firewall. Additionally, you should make sure that your browser is set to reject any websites that are not using an SSL/TLS certificate.

You should also be aware of the risks associated with downloading software from the internet. Before downloading any software, you should read the license agreement and check the publisher’s website for any information about the program. If the publisher is not a trusted source, you should avoid downloading the software.

Finally, you should consider using a secure web proxy. A secure web proxy will filter out any websites that are known to be malicious or contain malicious code. It will also help to protect your computer from root CAs being pushed onto it from malicious websites.

In summary, it is possible for a malicious website to push a root certificate authority (CA) as trusted onto your computer. To protect yourself, you should make sure that your computer’s security settings are up to date, your browser is set to reject websites that are not using an SSL/TLS certificate, and use a secure web proxy. By taking these steps, you can help to protect your computer from malicious websites pushing root CAs onto it.
