Sql Injection Attacks And A Web Application Environment

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

With the intoduction of Web 2.0, sharing information through social networking has increased and as there has been increased business/services over the internet websites are often attacked directly. Hackers either attempt to compromise the network or alternetivly the end-users opening the website.

Abstract - SQL injection is a technique where malicious users can inject SQL commands into an SQL statement through user input. It is among the most common application layer attack techniques used normally. SQL Injection is among topmost attack mechanisms used by malicious user to steal data from organizations. This is one of the types of attack which takes advantage of improper coding to inject SQL commands into form through user input to allow them to gain access to the data.

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.

The top ten most common database attacks are excessive privilege, privilege abuse, unauthorized privilege elevation, platform vulnerabilities, SQL injection, weak audit, denial of service, database protocol vulnerabilities, weak authentication, and exposure of backup data. (Schulman, 2012) The majority of these attacks can be mitigated by firewalls, password protection, and appropriate permissions.

Security is now and again called an "overall concern" in light of the fact that everything required in the Web administrations environment needs some level of insurance against the numerous dangers and difficulties that IT divisions must manage all the time. For instance, SOAP messages should be secure, WSDL records may should be secured against unapproved get to, firewall ports may require extra systems to make preparations for overwhelming burdens and to assess Web administrations messages, et cetera. Since Web administrations are intended for interoperability, an imperative objective of the security innovations is to empower execution environment advances to keep on working while adding security instruments to the Web administrations layers above them.

From the above code, we can tell how server send query to Database. But we can still guess to login without knowing the user’s passward by typing “bob’);-- “( space after the comment’--’ )

Recently, Aim Higher College has seen several cases of sensitive information being stolen from a student information system and posted on the Web. After reviewing Web server and database logs, you believe that the source of the problem is a SQL injection vulnerability. The vulnerability appears to exist in a Web application used by students to register for courses.

“Branch Locator” page is vulnerable to SQL injection attacks. This is a serious vulnerability which involves inserting malicious SQL statements into an input field for execution. By appending SQL statements to the URL of the Branch Locator page, information about the structure of the underlying database was collected. This information was then used to generate further malicious statements. The list of database objects, tables and columns were returned. The

There are various but similar SQL injection codes that are utilized to exploit website accounts. But the Hacker has to be well versed with SQL query language. Not that a quick search and some dedication to obtaining that information is not feasible. Finally having understood the step-by-step SQL injection execution, let’s look into how to mitigate SQL injections. (Kali, 2017)

SQL injection attacks pose a serious security threat and it has become a predominant type of attacks that target web applications utilizing the backend databases. It allows attackers to obtain unauthorized access to the database and retrieve potentially sensitive information. These attacks are launched through specially crafted input to trick the database into executing any SQL queries. In this paper I will present a review of different types of SQL injection and how they could be performed. I will also analyze some of prevention techniques available to mitigate the SQL injection attacks. Finally, I will discuss why it is very important and needs considerable attention.

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.

With advances in technology constantly happening, it can be hard to keep up with all of the latest trends. If organizations cannot keep up with the latest trends, it can lead to flaws in their security. Any flaws in security can have a detrimental effect on an organization’s database. Almost every organization has some sort of database, whether it is for maintaining customers, inventory, or vital information.

IJCSNS International Journal of Computer Science and Network Security, VOL.11 No.1, January 2011 197 An Approach to Detect and Prevent SQL Injection Attacks in Database Using Web Service IndraniBalasundaram 1 Dr. E. Ramaraj2 1 Lecturer, Department of Computer Science, Madurai Kamaraj University, Madurai 2 Director of Computer Centre Alagappa University, Karaikudi. Abstract SQL injection is an attack methodology that targets the data residing in a database through the firewall that shields it. The attack takes advantage of poor input validation in code and website administration.

It is proposed by Junjin [10] for detecting SQL injection attacks over the web application i.e. for tracing SQL input flow using SQLInjectionGen and attack input generation using
