When you install a web server on your PC, it is often times necessary to perform a free web server security test to make sure that your system has no security vulnerabilities. Vulnerability scans are performed by scanning the HTTP traffic sent from the web server. The scanning method for HTTP traffic is somewhat different from that of the usual traffic that comes through your email or IM. In particular, the difference in scanning protocol affects the response codes that are used when a hacker attempts to gain access to your server. In order to bypass these security checks, the hacker changes the IP addresses or ports that are normally used with standard HTTP.
One of the best ways to find out if your internet service provider has any flaws is to perform a free web server security test that checks for common flaws. Commonly, the scanning will detect holes in security which allow an attacker to gain access to your website and does not even have to be able to write code that could be exploited. Common problems that can be found during a scan include web application firewalls, databases, and configuration vulnerabilities. A web application firewall can prevent hackers from accessing your files, while database security checks identify if the information can be read from the database.
Another way to check to see if your web application security is up to date is to perform a free web server security test that compares your current SSL/TLS configuration to known weak spots in the SSL/TLS protocol. One of the most vulnerable areas for an SSL/TLS implementation is the usage of cookies. Cookies are used to track visitors to a website and can contain sensitive information such as IP addresses and URLs. An SSL/TLS implementation will commonly contain cookies, however the use of these can cause protocol failures and greatly affect the performance of websites. While a website can be adapted to eliminate cookies, this is a very time consuming process and may not always be possible.
A free web server security test that can identify phishing attempts and fraudulent websites can be performed using a free domain security radar tool. When you utilize a free web domain security testing service you can alert you to the presence of malicious websites falsifying innocent looking websites as legitimate. The tools work by scanning the URL’s in the body of text for common irregularities. The scan will then reveal if there is an encoding error or if there is a space character inserted.
It should be possible to create custom modules for web security testing purposes. One approach is to create a module that performs common functions for common HTTP protocols and look for HTTP connection leaks and any other weaknesses that may exist in the current platform. Another approach is to create a test harness that allows for the integration of different protocols within a web security suite. Some of the common tests that can be performed with the free web server security tools include FTP uploading and downloading, username guessing, denial of service, password guessing, and the protocol reverse engineering.
Many of the attacks against the HTTP server can also be conducted against the Cookie Flag module. This module controls the set of information sent with each HTTP request and has the ability to hijack information during server execution. A free web server security test that attacks the Cookie Flag must be able to identify the “Cookie” information within the response.
Some of the most popular methods of attacking the Cookie Flag include using Apache to hijack the” Cookie” directive, using curl to extract the” Cookie” information and using Mod CGI to change the “arge” of the response. Any requests with the “http” prefix before the”.” will be denied. There are two problems with this approach. First, most web applications that do not use Mod CGI will detect the attack and terminate the process before the “http” prefix is received.
Second, if the mod-cgic method of changing the “arge” of the response is employed, most sites will display an error message. The response will then be served without cookies. In addition, Mod-CGI modifies the response headers, so that most websites will reject the response. These vectors can be combined to create new vulnerabilities, as well.
