How to do HTTPS detection? Zero basic quick start tutorial

in the increasingly strict requirements of website security and compliance, HTTPS protocol has become the standard of website operation, it can not only ensure the security of user data transmission, but also improve the weight of the website in the search engine. However, many operators and webmasters with zero foundation have little knowledge of HTTPS detection methods, core points and subsequent optimization, and it is easy to ignore potential security risks. This article will disassemble the practical operation process of HTTPS detection in an all-round way, so that users with zero foundation can quickly get started and complete professional detection work.

What should be done before HTTPS detection?

before the official launch of HTTPS testing, adequate preparation can make the testing process smoother and the results more accurate and reliable.

1, confirm the basic information of the website

organize the domain name information of the website in advance, including the main domain name, sub-domain name, and the Internet Protocol Address of the server, space service provider, etc. This information can help the detection tool to more accurately locate the detection target and avoid the deviation of the detection results due to the lack of information, especially for websites with multiple sub-domains. The complete domain name list is the basis for the comprehensive detection of HTTPS.

2, sort out the current protocol status of the website

manually visit the website to confirm whether the website is currently HTTP or HTTPS protocol, and whether there are some abnormal page jumps. For example, some inner pages still use the HTTP protocol to load resources. This mixed content problem will affect the overall results of HTTPS detection. Early investigation can make subsequent detection more targeted, and obvious protocol adaptation problems can also be found in advance.

What are the commonly used HTTPS detection tools?

choosing the right HTTPS detection tool is the key to complete the detection efficiently. Different tools have different functions and can meet the detection needs of different scenarios.

1, online free testing tools

such tools have low operating thresholds and are suitable for zero-based users to quickly complete HTTPS detection. Common ones include SSL Server Test of SSL Labs and HTTPS detection function of webmaster tools. Taking SSL Server Test as an example, just enter the website domain name and wait a few minutes to get a complete test report including certificate validity, protocol support, security rating, etc. The content of the report is easy to understand, and the existing risk points will be marked.

2, local client side detection tool

for users who need to frequently carry out HTTPS detection, local client side tools are more efficient, such as OpenSSL, Nmap, etc. This kind of tool needs to be installed on the computer, and the detection is completed through command line operation, which is more powerful and can customize the detection parameters. It is suitable for technicians who have deep needs for HTTPS detection, but the operation threshold is relatively high. Users with zero basics can start with online tools first.

3, HTTPS detection needs to focus on what points?

get the HTTPS test report, you need to focus on the core points of interpretation in order to accurately judge whether the HTTPS protocol status of the website is in compliance.

1, SSL certificate validity

this is the core content of HTTPS detection, it is necessary to focus on whether the certificate authority is regular, whether the certificate is within the valid period, and whether the domain name matches the certificate binding. If the certificate expires or the domain name does not match, the browser will prompt that the website is not safe, which directly affects the user's willingness to visit. In serious cases, the website cannot be opened normally.

2, mixed content problem investigation

HTTPS test report will mark whether there is mixed content, that is, the situation where HTTPS and HTTP resources are loaded on the page at the same time. This kind of problem does not seem to affect the opening of the website, but it will reduce the security level of the entire page. The browser will also display an insecure prompt in the address bar, which will affect the user's trust. It will also affect the overall rating of HTTPS detection.

3, protocol compatibility testing

check the content of the protocol version in the HTTPS test report to confirm whether the website supports TLS1.2 and above, and whether the old version of the protocol with security bugs such as SSL3.0 is disabled. Insufficient protocol compatibility will cause some old browsers to fail to access the website normally, affecting the coverage and user experience of the website.

4. How to optimize the website after HTTPS detection?

completion of HTTPS detection, timely optimization for the problems pointed out in the report, in order to truly play the security advantages of HTTPS protocol.

1, certificate problem optimization

If the HTTPS test finds that the certificate has expired, you need to contact the certificate authority in time to reapply or renew the certificate. After the installation is completed, the HTTPS test will be carried out again to confirm that it will take effect. If there is a domain name mismatch problem, you need to check the domain name information bound to the certificate and reapply for a certificate that exactly matches the website domain name to avoid incompatibility.

2, mixed content issue fix

for mixed content detected by HTTPS, it is necessary to check the resource links in the page one by one, replace all resource links starting with HTTP with HTTPS, or use relative paths to load resources. For third-party resources that cannot be directly replaced, they can be replaced with third-party services that support the HTTPS protocol to ensure that the resource loading of the entire page is completed in the HTTPS environment.

To sum up, HTTPS detection is an important part of ensuring website security compliance. From the early information preparation, to the selection of appropriate tools to carry out detection, to the interpretation of core points and subsequent optimization, each step is closely related. Zero-based users only need to follow the process of this article step by step, they can quickly master the practical skills of HTTPS detection, investigate and repair the security risks of the website in time, improve the security and user trust of the website, and build a solid foundation for the stable operation of the website.
