Use Of Wcf Services And Combination Of Methods For Preventing Sql Injection Attacks Essay

Everyday tech users are increasingly engaged with web and mobile applications. These programs have many uses and can be very helpful in progressive usage. However, these applications also serve as the most accessible point of entry for malicious attackers to wreak havoc. The continual growth and usage of web-applications makes the infrastructure one that is susceptible to attack due to lack of thorough security implementation. The Open Web Application Security Project (OWASP) is a community-based non-profit organization that concentrates on increasing the safety in the realm of web applications. It was started in 2001 and ever since then its primary goal has been to create a high level of transparency in the web applications and software

SQL Injection – an input validation attack specific to database applications where SQL code is inserted into application queries to manipulate the database.

In this thesis, focus on the security aspect of the client side, as well as in terms of the server, where the main objective of this security system to prevent attackers from exploiting the weaknesses of the client side because this would lead ultimately

In this chapter, we will discuss the historical background on the objectives of Web services and security,and it will be touched upon the other subjects such us Confidentiality, integrity, authenticity services, authentication methods, Zero-Knowledge Proof protocols, and Diffie-Hellman key exchange is also discussed.

The Aim Higher college has recently had some issues of sensitive information being stolen from students when registering for classes. I believe that the web application that the student information system is using is a problem named SQL injection. A SQL injection attack is an attack where the attacker can run malicious SQL queries against a web application’s database server and it can be a danger for the users who access the web page because the hacker will look for their personal information records, then delete it or modify the information gained. This type of attack is no joke we have to take action and create a plan to resolve this vulnerability on our database, so the students will register for their courses with our security on their side.

Firstly I will like to talk about the Microsoft SQL Server. According to Vincent (July 2010) Microsoft SQL Server is a relational database managing software developed by Microsoft. Since many years back (1989) the SQL Server has been experiencing a lot attacks. For example

With the quick advancement of Internet, system database security has turned into the center of system security. The exploration of database security innovation against SQL assaults has turned out to be exceptionally earnest. In this paper, we investigate standards of SQL assaults, contemplate a database insurance framework which is utilized between the Web application and the database. The framework gives distinctive defensive measures to customary clients and directors to adequately ensure the security of the database. the part of a Web application and database in the database between the security framework for customary clients and directors

SQL injections are the serious threat to the web applications; they permit attackers to acquire unlimited access to the databases and sensitive data these databases contain. Despite the fact that analysts and experts have proposed different strategies to address the SQL injection attacks. Many solutions are able to solve only some of the issues related to it. This document provides the types

SQL injection is a technique where malicious users inject SQL commands into an SQL statement, via web page input. Injected SQL commands can alter SQL statement and compromise the security of a web application. SQL injection is one of the oldest, most prevalent and dangerous of web application vulnerability. I believe attackers could steal information by following methods. Most web pages have users or given user id to login, and original idea

Use software that was developed using secure software design (SSD) model. For example, software developers should not write dynamic queries for databases and prevent user supplied input which contains malicious SQL from affecting the logic of the executed query. This will help with the following security threat: SQL injection, buffer

The Proliferation and advances in computer network have led to increase Distributed database system In Distributed Database Different user are connected for accessing the data. In distributed database the data from the single local computer can be transferred or distributed on various computer connected at the same physical location. The Data from the database can be distributed to the multiple physical loacation. It is a powerful technology with great potential to help companies focus on how to transfer information by their main branch to the different sub-branch or collected data from their sub branch to their main branch. This is not the easy as we se there is different types of corrupted data on the remote computers. There is also possibility of problem in physical location. The network must be failed in between data transfer. There is also possibility of hacking data in between tansfering. There is some techniques used by Distributed Database for handling this types of problems during information transfering over the different networks.

With the advent of Internet, web applications have become a day to day feature in our lives. Also with the constant usage of online services increasing every day, there has been an equally growing concern regarding the security threats in web applications. One of the most common attacks exploiting the vulnerabilities of various types of applications along with web applications is through the Structured Query Language Injection Attack also known as SQL Injection Attack. Based on a recent study by OWASP, SQL injection attack has the highest rank in revealing web based vulnerabilities. One of the major motivation for the attacker to perform SQL injection attack is for retrieving all the contents from the database without any authorization or permission. It is a code injection technique where an attacker inserts a malicious query in the original legitimate SQL query. After the execution of the query, the attacker has the access to the database and can obtain, change, and update data for which he/she does not have any permission.

SQL Injection is one of the main database attack mechanisms used by hackers to loot organization 's data from databases. Hacker target the application layer program and takes advantage of the improper coding methods to inject SQL command into a web form and then gain access to the database. SQL injection may adversely affect the integrity of the database and may reveal sensitive data of the organization. The intensity of the SQL injection attack vary depend on the capabilities of the backend database in use. With the help of SQL injection hacker can change existing queries, attach additional queries, read in or write to file or execute operating system command from the database. To protect organization data from SQL injection we need to apply security measures in the application layer and in the database layer. The purpose of this study is to analyze the database functionalities/security holes, mainly Oracle and MySQL, and propose the preventive measures database developers need to consider in the database layer while working with these databases to secure data from SQL injection.

Web applications are nowadays serving as a company’s public face to the internet. This has created the need to identify threats and attacks directed to data servers and web applications. Hackers exploit vulnerabilities in input validation and authentication affecting the web application in order to gain illegal access and disclose sensitive data or manipulate it to their benefits.

To move around the network securely and safely for organizations is very important. With the increase of this activity new security challenges came in existence. There are many malicious requesters who try to use organization’s web services by sending fake requests. So there is need to identify which request is sent by genuine requester and malicious requester. To avoid requests from fake requesters there is requirement of access control model that can store data about the person who made request for web service at the time of access request and utilize this data effectively in future while making access control decisions. This
