We follow a systematic and yet agile approach to test website security. This helps our customers gain an extremly accurate and elaborate results along with a knowledge base and years of experience on the subject matter. We follow OWASP Top 10 standard to find and report vulnerabilities.
Vulnerabilities in PHP can be in several different forms. The basic definition of vulnerability is some weakness in the system that allows someone to do something malicious to the system, which in this case is the web server. One form of vulnerability is via a poorly written PHP script by a user, which can be done by mistake or with malicious intent. Another form is by not understanding all the various settings that can be used with PHP and thus the administrator of the web server does not implement settings which are necessary for security. There are other vulnerabilities that exist which can cause a denial of service to the user (crashing the web server, flooding the network with traffic to where it is unusable, etc.). The following identifies some examples of these vulnerabilities and gives a more detailed explanation of each type of vulnerability.
Valency Networks is one of the best web application and website security testing company in India and abroad. Our experience tells us that, while PHP scripts are not inherently bad, the user could either inadvertently write a script that allows the vulnerability or maliciously create a script to take advantage of certain PHP functions. A web administrator may not need to worry about such scripts for the main website that he/she manages, but other users on the system which create and publish web content could create bad PHP scripts. The web server administrator must be aware of such issues with PHP so none of the pages on the system have vulnerabilities.
There are two major types of PHP vulnerabilities, local and remote. The local vulnerabilities are designed such that the attack is being made on the system on which the PHP script resides. A remote vulnerability executes a PHP script on one web server, which in turn goes out to get another PHP script and then is executed on the web server. In this instance, an attacker could place a PHP script on some other server which would cause vulnerability to a web server which executed it. Then the attacker can essentially tell the web server they are trying to exploit to grab that PHP file and execute it, causing the web server to be vulnerable.
Some vulnerabilities are introduced by incorrectly or not setting certain configuration parameters for the PHP module. Certain commands are not as well known as others or may not be documented properly. Many of these configuration parameters are known by the PHP community, but many web server administrators are not part of that community and do not know much about PHP.
Microsoft .NET Framework is prone to a security-bypass vulnerability. An attacker can exploit this issue to bypass certain security restrictions and perform unauthorized actions. This may aid in further attacks. Any system designed without considering security assessment leads to non compliance and may come under security threats. Such systems are vulnerable to harmful attacks. The guide below will foster the strengthening of applications and mitigate the risk of probable attacks and reduce unauthorized activities.Read More
One of the main design considerations for the Java platform is to provide a secure environment for executing mobile code. Java comes with its own unique set of security challenges. While the Java security architecture can protect users and systems from hostile programs downloaded over a network, it cannot defend against implementation bugs that occur in trusted code. Such bugs can inadvertently open the very holes that the security architecture was designed to contain, including access to files, printers, webcams, microphones, and the network from behind firewalls. In severe cases local programs may be executed or Java security disabled. These bugs can potentially be used to turn the machine into a zombie computer, steal confidential data from machine and intranet, spy through attached devices, prevent useful operation of the machine, assist further attacks, and many other malicious activities. The choice of language system impacts the robustness of any software program. The Java language and virtual machine provide many features to mitigate common programming mistakes. The language is type-safe, and the runtime provides automatic memory management and bounds-checking on arrays. Java programs and libraries check for illegal state at the earliest opportunity. These features also make Java programs highly resistant to the stack-smashing and buffer overflow attacks possible in the C and to a lesser extent C++ programming languages. These attacks have been described as the single most pernicious problem in computer security today. The explicit static typing of Java makes code easy to understand (and facilitates static analysis), and the dynamic checks ensure unexpected conditions result in predictable behaviour .Read More
