You must have visited a website, but faced with the message “This site is not secure” or “Your connection is not secure”. There are several ways to analyze problems, measure risks, and reduce threats or hazards. But what exactly is the connection is not secure? When your browser marks a website as an insecure site, the browser actually detects a problem with SSL that validates the site’s identity.
SSL certificates use encryption to verify identity, SSL is also a complete encryption protocol, and SSL is not technically an encrypted connection. Unfortunately, it is technically possible for our computers to make encrypted connections to malicious sites masquerading as legitimate sites. 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 lost, it won’t make an encrypted connection. Basically, every site that has an SSL certificate, also uses SSL encryption, so the two go hand in hand.
Cause Your Connection is Not Secure
There are several reasons why a site might be listed as an unsafe site. One possibility is that the site you are visiting has a certificate with an incorrect configuration. Setting an SSL certificate is indeed difficult, especially if the site administrator has upgraded the SSL service, because not everyone does it correctly. Configuration errors can also occur when the server software is updated and is potentially out of sync. It could also be because the site administrator forgot to renew the SSL certificate. These things are common because maintaining an SSL certificate is not easy. The certificate also becomes invalid if the admin changes the site’s hosting provider or internet service provider. These changes cause the new URL or IP Address does not match, because it is not registered on the previous certificate.
Errors that occur are not always the fault of the website manager. Browsers do go hand in hand with certificates, but don’t always synchronize with all the latest ones. So, if your browser isn’t the latest version, it could be that that causes the copy of the certificate to disappear. The last possibility is that it is possible that the site you are aiming for has never had a certificate. Certified certificates that can be trusted require a fee. All certificates also require technical knowledge. This is why some website managers choose not to question certificates.
How to Identify an Unsafe Website
Most modern browsers consistently and explicitly identify unsafe sites.
- Browser on the desktop
When a site experiences problems like the one above, the browser will add a Not Secure tag at the left end of the navigation (where the URL is displayed), usually with a picture of an unlocked padlock. The padlock image is accompanied by an “i” information icon, or other cues that describe 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
Because of the compact design and focus on efficient use of the screen, browsers on mobile phones usually do not display the text Your connection is not secure. They only rely on the differentiation of icons. Like a browser on a desktop, a browser on a cell phone shows a secure site with a picture of a locked padlock in green. Meanwhile, insecure sites are marked with an open padlock or “i” information icon. Browsers on mobile phones can also display information related to the site by clicking the information icon.
How to Overcome Your Connection is Not Secure
- Update the browser. The easiest thing to do is to update the browser to the most recent version.
- Use SSL checker. You can check by entering the URL into the SSL checker. SSL checker will tell you everything about the site. From the IP Address, the certificate issuer, until when the certificate expires. After the SSL checker provides these results, you can compare them with the information you can by clicking on the information icon on the website. If there are differences between the two, it will be difficult for you to identify the problem. But when they display the same information, the error will only be a clue about how serious the problem on the site.
- Use HTTPS Everywhere. If the above examination reveals a simple problem, which actually has a valid certificate, you only need to take precautions before browsing again. For computers that use Firefox, Chrome, or Opera as a browser, you can install the HTTPS Everywhere extension to ensure all connections are encrypted. By installing the extension, if the certificates do not match, you still have an encrypted connection.
- Avoid web sites. If you have run everything but there is still an error, it could be that the problem is a serious problem. You must be careful. Make sure you enter the URL correctly. If you have previously bookmarked, open the website from Bookmark and check if there is a tag Your connection is not secure (Not Secure). If the tag exists, don’t visit the site for a while. Let the website manager resolve the problem.
Don’t Carelessly Enter the Website
There are several reasons why a site might be listed as an unsafe site. Your connection is not secure can occur because SSL certificate settings are in trouble. The browser will give a warning if the website is indeed a site that is not safe. So it’s better not to open the website for a while. Look for sites that are completely safe so that sensitive data remains protected.
