Cause Your Connection Isn't Secure
SSL certificates use encryption to perform identity verification, SSL is also a complete encryption protocol, and SSL is technically not an encrypted connection. Unfortunately, it is technically possible for our computer to establish an encrypted connection to a malicious site disguised as a legitimate site. Your Browser only understands encryption by using an SSL certificate. So if the site has a valid certificate, then it encrypts the connection with the site. But if the site's certificate is invalid or missing, it will not create an encrypted connection. Basically, any site that has an SSL certificate also uses SSL encryption, then both roads in tandem.
Causes Your Connection isn't Secure
There are several reasons why sites may be listed as unsafe sites. One of the possibilities is that the site you visit has a certificate with the wrong configuration. Setting up an SSL certificate is difficult, especially if the site administrator has upgraded the SSL service because not everyone is doing it right. Configuration errors can also occur when the server software is updated and potentially unsynchronized. It could also be because the site administrator forgot to renew the SSL certificate. These things are commonplace because maintaining an SSL certificate isn't an easy thing. The certificate also becomes invalid if the admin changes the site's hosting provider or the Internet service, provider. The change causes the new URL or IP Address do not match because it isn't listed in the previous certificate.
Errors that occur are not necessarily a website manager error. The Browser is in tandem with the certificate but doesn't always synchronize with all the latest. So if your browser isn't the latest version, it could cause a copy of the certificate to disappear. The last possibility is that the site you're aiming for has never had a certificate. Reputable and trustworthy certificates require a fee. All certificates also require technical knowledge. This is why some website managers choose not to question certificates.
How to identify unsafe websites
Most modern browsers consistently and explicitly identify unsafe sites.
Browser on desktop
When a site encounters a constraint like the one above, the browser will add a Not Secure tag at the far left of the navigation (where the URL is displayed), usually with a picture of an unlocked padlock. The image of the padlock is accompanied by an "I" information icon, or other gesture describing the site as unsafe. Users can read the information by clicking the Not Secure tag. The information displayed is about the site itself and why the site does not meet browser security standards.
Browser on mobile
Due to its compact design and focus on efficiency of screen use, browsers on mobile phones usually don't display the text of Your connection isn't secure. They rely solely on differentiation on the icons. Like the browser on the desktop, the browser on the phone shows a secure site with a green locked lock image. While for unsafe sites are marked with an open padlock or an "I" information icon. The Browser on your phone can also display information related to that site by clicking the information icon.
How to solve Your Connection isn't Secure
- Update your browser. The easiest thing to do is to update your browser to the most recent version.
- Use an SSL checker. You can check it by entering the URL into the SSL checker. The SSL Checker will tell you all about the site. From the IP Address, the certificate issuer, until when the certificate expires. Once the SSL checker provides the result, you can compare it with the information you can by clicking on the information icon on the website. If there is a difference between the two, you will be difficult to identify the problem. But when both of them display the same information, the mistake will actually be a clue about how serious the problem is at the site.
- Use HTTPS Everywhere. If the above checks reveal a simple problem, which actually has a valid certificate, you only need to take precautions before returning to browsing. For computers using Firefox, Chrome, or Opera as browsers, you can install the HTTPS Everywhere extension to ensure all your connections are encrypted. By installing the extension, if the certificate doesn't match, you still have an encrypted connection.
- Avoid websites. If you've run everything but there's still an error, it could be a serious problem. You have to be careful. Make sure you enter the URL correctly. If you've previously bookmarked, open the website from bookmarks and check if Your connection isn't secure (Not Secure) tag. If the tag exists, do not visit the site for a while. Let the website maintainer resolve the issue.
There are several reasons why sites may be listed as unsafe sites. Your connection isn't secure may occur due to the setting of the SSL certificate being problematic. The Browser will give you a warning if the website is indeed an unsafe site. So it's better not to open the website for a while. Find a completely secure site to keep sensitive data protected.
