in the process of website operation, security risks such as hidden threats always exist, small data leakage to the site is tampered with, may bring serious losses to operators and users. Website vulnerability scanning as a pre-security protection means, can find the hidden security bugs of the website in advance, build a security barrier for the website. This article will start from a zero-based perspective, step by step dismantling the core content of website vulnerability scanning operation logic, tool selection, result processing, etc., so that novices can quickly get started and complete professional security testing.
, how to choose a suitable website vulnerability scanning tool?
the first step to carry out website vulnerability scanning is to choose the right tool to adapt to their own needs, and the function focus and operation threshold of different tools are quite different.
1, online free website vulnerability scanning tool
such tools do not need to download and install, can be used directly through the web, the operating threshold is very low, suitable for personal webmaster or small website basic detection. Common such as webmaster platform security detection tools, 360 website security detection, can quickly complete the scanning of common vulnerabilities, output simple and easy to understand the test report, and do not need to have professional technical knowledge to read the results.
2, locally installed professional website vulnerability scanning tool
such tools need to be downloaded and installed on local devices, such as Nessus, AWVS, etc., the functions are more comprehensive, covering all kinds of vulnerability detection from basic to deep, suitable for users or enterprise-level websites with a certain technical foundation. They support custom scanning rules, batch scanning of multiple sites, and can generate detailed vulnerability analysis reports to provide accurate basis for subsequent fixes, but the operation is relatively complicated and requires time to familiarize with the functions.
What are the basic steps of website vulnerability scanning?
select the tool, you can carry out website vulnerability scanning according to the standardized process, which is the key to obtain accurate detection results.
1, set the scanning target and parameters
first enter the website domain name or Internet Protocol Address to be scanned in the tool. Some tools also support adding multiple scanning targets to achieve batch detection. Then set the scanning parameters according to the website type, such as selecting the type of vulnerability scanned, such as SQL injection, XSS cross-site scripting, weak passwords, etc. You can also choose full-type scanning to cover all possible vulnerabilities. At the same time, set the scanning frequency reasonably to avoid excessive scanning affecting the normal operation of the website.
2, start scanning and monitor the process
confirm that the parameters are set correctly, click the start button to start the website vulnerability scan. The progress can be monitored in real time during the scanning process, and some tools will display information such as the type of vulnerability currently scanned and the number of pages detected. If it is a large website, the scan may take a long time. Try not to interrupt the operation of the tool during this period to ensure the integrity of the scan results.
3, export and save scan reports
scan is completed, the tool will automatically generate a scan report, including the severity of the vulnerability, the scope of impact, detection location and other information. To export and save the report in time, it is recommended to store it in PDF or Word format, which is convenient for subsequent viewing and comparison, and can also provide complete reference materials for subsequent vulnerability fixes.
How to interpret the detection results of website vulnerability scanning?
get the website vulnerability scanning report, accurate interpretation of the results is the core premise of subsequent repair, different levels of vulnerability processing priority difference is obvious.
1, identify the severity of the vulnerability
most website vulnerability scanning tools will be classified into high-risk, medium-risk, low-risk and prompt four levels. High-risk vulnerabilities such as SQL injection, remote code execution, etc., may directly lead to the website is controlled or data leakage, need to be dealt with immediately; medium-risk vulnerabilities may affect the normal operation of some functions of the website, need to be repaired in the short term; low-risk and prompt vulnerabilities have less impact on the website, and can be repaired according to the actual situation.
2, understand the scope of the vulnerability
report will also clearly mark the scope of the vulnerability, such as whether there is a vulnerability in a single page, or there is a problem with the permission system of the entire website. Understanding the scope of influence can help users accurately locate the repair location and avoid blind investigation and waste of time. At the same time, some reports will be accompanied by the principle of vulnerabilities, which can help users understand the cause of vulnerabilities and avoid similar problems from the root cause.
4. What are the suggestions for bug repair after website vulnerability scanning?
complete the website vulnerability scanning and interpretation of the results, timely repair of vulnerabilities in order to truly achieve the purpose of website security protection.
1, prioritize high-risk vulnerabilities
prioritize high-risk vulnerabilities according to the ranking of website vulnerability scanning reports. You can follow the repair suggestions in the report, such as replacing more complex passwords immediately for weak password vulnerabilities; for SQL injection vulnerabilities, filter and verify the database query statements of the website, or use parameterized query methods to avoid vulnerabilities from being exploited. If your own technology is insufficient, you can seek the help of professional security personnel.
2, regular review to verify the repair effect
after the vulnerability repair is completed, it is necessary to carry out the website vulnerability scan again for review to confirm whether the vulnerability has been completely repaired. Some vulnerabilities may be detected again because of incomplete repair or associated vulnerabilities, so the review link is essential. At the same time, it is necessary to record the comparison of the scan report before and after the repair to form a complete security inspection file to provide reference for subsequent website security management.
To sum up, website vulnerability scanning is a key link in the website security protection system. From tool selection and operation execution to result interpretation and repair, each step has a clear operation logic. Zero-based users can quickly master website vulnerability scanning skills as long as they follow the process in this article. Normally carry out website vulnerability scanning, which can find and repair security risks in time, effectively improve the security and stability of the website, and provide reliable protection for website operation and user data security.
