A web scanner is a software program that allows you to scan your website for vulnerabilities, such as SQL injection (SQLI) attacks and cross-site scripting (XSS) vulnerabilities. Antivirus software looks for malicious files on your computer that have been sent to you by hackers or people who want to steal your personal information. Like antivirus software, a web scanner scans the Internet for websites that contain malware, spyware, and other malicious code. The program checks all links and images on every page of your site to ensure they are legitimate. The tool can also search for security vulnerabilities in websites while testing their usability.
Types of Scanners
There are three basic types of scanners:HTTP:
This type of scanner will only check HTTP traffic on your website. Using this type of scanner is best if you need to ensure that all content served via HTTP will be tested by your web application scanner.
FTP:
This type of scanner will only check FTP traffic on your website. Using this type of scanner is best to ensure that all content served via FTP will be tested by your web application scanner.
HTTPS:
This type of scanner will only check HTTPS traffic on your website. Using this type of scanner is best to ensure that all content served via HTTPS will be tested by your web application scanner.
Functions of a Web Scanner
Scanner software helps keep your website safe from malware attacks. It scans every page of your website and protects against many kinds of attacks, including:
- Dangerous links that can redirect users to phishing websites
- Malicious code embedded in banner ads or popups
- Hacker malware that can infect your computer when you visit a compromised website
The scanning tools can be helpful in many ways, including:
Spoofing:
The scanners can sometimes detect if a virus or hacker has compromised a website or system. This tool can help you discover where your company's data was lost or stolen.
Security assessment:
They can perform security assessments to test security controls and vulnerabilities on your company's network and systems. This function helps identify weaknesses and make improvements where necessary.
Usability testing:
These tools can also thrive in usability testing when trying new software or web applications before launch. It also helps improve your website's performance by providing statistics about page speed, page loading time, etc. In addition, it also provides details on errors occurring on a page.
How Web Scanner Protects Your Website From Malware
Although it's hard to imagine a web application not being vulnerable, many ways are available to minimize the impact of an attack. One of the most effective ways is using a security web scanner to find and fix potential issues before hackers exploit them. Scanners can be handy in finding security vulnerabilities that other methods cannot detect. For example, a scanner can detect SQL injection attacks on your website and help keep your database safe from hackers.
You can use the scanner to find out whether your website has security holes and help you fix them before it's too late. The program scans the entire site, including all HTML code, CSS stylesheets, JavaScript and images. It checks if there are any errors in files or databases. If problems arise, the program will display them and let you know what to fix before it's too late.
The scanner provides a comprehensive database of malicious files, including trojans, worms and viruses. This database is updated regularly to keep your website safe from new threats. They do this by analyzing the HTML source code of a site. The code makes up your site, including images, Javascript and CSS. The scanner works out what each line of code does, how it interacts with other lines of code and whether there is any potential for an attack.
Conclusion
A web scanner is a program that checks your website for any threats. It can also detect and prevent harmful content from being displayed on your website. There are several tools available, each with its advantages and disadvantages. Some scanners are better than others at detecting threats. While some may only find one type of threat on a page, others may see multiple types. So it is paramount for every user to take care of their online safety and avoid visiting websites with malicious codes. The scanner helps you identify malicious codes and help you remove them from your website to ensure they don't spread to other sites.
