A Survey on SQL injection: vulnerabilities, attacks, and prevention techniques

In this paper, we present a detailed review on various types of SQL injection attacks, vulnerabilities, and prevention techniques. Alongside presenting our findings from the survey, we also note down future expectations and possible development of countermeasures against SQL injection attacks

An overview of the planned CCAT software system

CCAT will be a 25m diameter sub-millimeter telescope capable of operating in the 0.2 to 2.1mm wavelength range. It will be located at an altitude of 5600m on Cerro Chajnantor in northern Chile near the ALMA site. The anticipated first generation instruments include large format (60,000 pixel) kinetic inductance detector (KID) cameras, a large format heterodyne array and a direct detection multi-object spectrometer. The paper describes the architecture of the CCAT software and the development strategy.Comment: 17 pages, 6 figures, to appear in Software and Cyberinfrastructure for Astronomy III, Chiozzi & Radziwill (eds), Proc.

Stateful Testing: Finding More Errors in Code and Contracts

Automated random testing has shown to be an effective approach to finding faults but still faces a major unsolved issue: how to generate test inputs diverse enough to find many faults and find them quickly. Stateful testing, the automated testing technique introduced in this article, generates new test cases that improve an existing test suite. The generated test cases are designed to violate the dynamically inferred contracts (invariants) characterizing the existing test suite. As a consequence, they are in a good position to detect new errors, and also to improve the accuracy of the inferred contracts by discovering those that are unsound. Experiments on 13 data structure classes totalling over 28,000 lines of code demonstrate the effectiveness of stateful testing in improving over the results of long sessions of random testing: stateful testing found 68.4% new errors and improved the accuracy of automatically inferred contracts to over 99%, with just a 7% time overhead.Comment: 11 pages, 3 figure

A detailed survey on various aspects of SQL injection in web applications: vulnerabilities, innovative attacks and remedies

In today’s world, Web applications play a very important role in individual life as well as in any country’s development. Web applications have gone through a very rapid growth in the recent years and their adoption is moving faster than that was expected few years ago. Now-a-days, billions of transactions are done online with the aid of different Web applications. Though these applications are used by hundreds of people, in many cases the security level is weak, which makes them vulnerable to get compromised. In most of the scenarios, a user has to be identified before any communication is established with the backend database. An arbitrary user should not be allowed access to the system without proof of valid credentials. However, a crafted injection gives access to unauthorized users. This is mostly accomplished via SQL Injection input. In spite of the development of different approaches to prevent SQL injection, it still remains an alarming threat to Web applications. In this paper, we present a detailed survey on various types of SQL Injection vulnerabilities, attacks, and their prevention techniques. Alongside presenting our findings from the study, we also note down future expectations and possible development of countermeasures against SQL Injection attacks

Optimization of Asset Allocation

ABC International Inc. is a leading contractor along significant mining and offshore operations. It owns a huge count of equipment, which is more than 32,000, and the count is increasing with expanding business. Equipment managers are currently required to find and append all the details of equipment at different locations manually. This takes lot of time and effort. Also the accuracy of the data is also a challenge in some situations. This should be handled through an automated system called Optimization of asset allocation where an equipment inventory report is generated which includes all equipment attributes. This can be achieved through SSRS (SQL Server Reporting Services)

Survey and Comparative Analysis of SQL Injection Attacks, Detection and Prevention Techniques for Web Applications Security

Web applications witnessed a rapid growth for online business and transactions are expected to be secure, efficient and reliable to the users against any form of injection attacks. SQL injection is one of the most common application layer attack techniques used today by hackers to steal data from organizations. It is a technique that exploits a security vulnerability occurring in the database layer of a web application. The attack takes advantage of poor input validation in code and website administration. It allows attackers to obtain illegitimate access to the backend database to change the intended application generated SQL queries. . In spite of the development of different approaches to prevent SQL injection, it still remains a frightening risk to web applications. In this paper, we present a detailed review on various types of SQL injection attacks, detection and prevention techniques, and their comparative analysis based on the performance and practicality.

An Evaluation of Open Source Unit Testing Tools Suitable for Data Warehouse Testing

Verification and validation are two important processes in the software system lifecycle. Despite the importance of these processes, a recent survey has shown that testing of data warehouse systems is currently neglected. The survey participants named besides others modest budget and the lack of appropriate tools as potential reasons for this circumstance. In order to verify these reasons, the paper at hand presents an evaluation of unit testing tools suitable for data warehouse testing. To address the modest budget problem, the range of evaluation candidates is limited to no charge, open source solutions, namely AnyDbTest, BI.Quality, DbFit, DbUnit, NDbUnit, SQLUnit, TSQLUnit, and utPLSQL. The evaluation follows the IEEE 14102-2010 guidelines for evaluation and selection of computeraided software engineering tools in order to guarantee benefits from a practioners’ as well as scientific point of view. It results in a detailed overview of how the testing tools meet criteria such as different testing functionalities. At least one tool, namely DbFit, can be identified as a promising candidate with regard to the requirements
