A classification of SQL injection attacking vector as of 2010. In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).
Code injection is the malicious injection or introduction of code into an application. Some web servers have a guestbook script, which accepts small messages from users and typically receives messages such as: Very nice site! However, a malicious person may know of a code injection vulnerability in the guestbook and enter a message such as:
In applied statistics, the Morris method for global sensitivity analysis is a so-called one-factor-at-a-time method, meaning that in each run only one input parameter is given a new value. It facilitates a global sensitivity analysis by making a number r {\displaystyle r} of local changes at different points x ( 1 → r ) {\displaystyle x(1 ...
MALPAS – A formal methods tool that uses directed graphs and regular algebra to prove that software under analysis correctly meets its mathematical specification. Polyspace – Uses abstract interpretation, a formal methods based technique, [17] to detect and prove the absence of certain run time errors in source code for C/C++, and Ada
SQL injection attacks and cross-site scripting fall into this category. Memory safety. In memory-unsafe programming languages, lower-level issues such as buffer overflows and race conditions can be exploited to take partial or complete control of the software. Spoofing and friends.
Analysis refers to dividing a whole into its separate components for individual examination. [10] Data analysis is a process for obtaining raw data, and subsequently converting it into information useful for decision-making by users. [1] Data is collected and analyzed to answer questions, test hypotheses, or disprove theories. [11]
Static program analysis analyzes a program without actually executing it. This might lead to false positives where the tool reports problems with the program that do not actually exist. Fuzzing in combination with dynamic program analysis can be used to try to generate an input that actually witnesses the reported problem. [51]
Different levels of analysis include: function level - sequences of instruction. file or class-level - an extensible program-code-template for object creation. application level - a program or group of programs that interact. The scope of the analysis determines its accuracy and capacity to detect vulnerabilities using contextual information. [8]
