Source code injection is a kind of attack in which applications are modified from the outside by injecting pieces of code that are intended to modify how these applications operate and the functions of the application are changed massively. This kind of attack makes the applications that are being affected and attacked more vulnerable to the attacks that are being meted out on them and with this in mind, the applications can respond to the demands of the attackers that have injected the code into the applications and with this in mind, the performance of the application is greatly impacted.
The other reason for the source code injection being very dangerous for the modern application is the fact that the modification of the internal structure of the application makes it very hard for this application to run the functions and operations that were originally meant for it and this keeps the application exposed to other dangers that result from the modification of the source code.
The source code getting modified could also mean that security weaknesses are being introduced into the application and these weaknesses are being taken advantage of by the hackers and programmers that introduced them into the application in the form of the source code injection.
The source code injection also makes the application perform less effectively than it was originally designed and intended to operate which is a reason why modern applications are designed to stop working or shut down some of the sessions when the digital signature of the application itself has been modified. This is the reason modern applications are being designed with a unique digital signature that will indicate whether the internal structure of the application has been modified or not.
With this reference in place, the source code injection will be very easy to observe, and noticing it once it has taken place will be much easier as the application will be able to note the difference in the running of the application and this will prompt it to alert other applications that are charged with security such as firewalls and other applications on the system.
With this made possible, the dangers of the source code injections are greatly reduced with the users of the systems getting to make use of the application without the modification of the source code which means they can make full use of the application and this also makes it possible for them to have an easier time with the application.
The security of modern information systems is derived from the very applications that are run on the systems and with applications being secured against the source code injection kind of attacks, they can stay safe and secure away from the attacks of the hackers that seek to introduced flaws to normally functional applications which also makes it harder for the hacker to obtain information from the application or take advantage of it in any way.
