Sql Attack Paper

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

Each distributed DB perform some procedures to protect the data from any threats may occur through transactions. First is access control methodology which prevent unauthorized access to data. Second, inference control which prohibit users from inferring confidential data of other individuals using queries. Finally, flow control to prevent information from flowing to unauthorized persons in a way that violates organization policies.

5) The SQL keyword CONSTRAINT is used in conjunction with the SQL keywords PRIMARY KEY and

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.

There are several attacks that target databases as a sensitive source of data. According to Schulman’s article (2015) “Top 10 Database Attacks”, some of these attacks uses existing vulnerability in the underlying platform, database

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.

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

The company can prevent, remediate, or mitigate the attacks. During the establishment of prevention and

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.

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.

Database security mainly concerns with protecting data and the applications of the databases that are stored. In the realms of Information security and computer security, the database security is the special topic. Database administrators may also be responsible for misconfiguration of controls within the software where database is stored. Database monitoring is also an important security layer. Electronic signatures and encryption and many other new technique are introduced to protect databases. Over the years, the database security has developed a very large number of different techniques to assure integrity, availability, and data confidentiality. However, there are also threats, which are related to these databases. The threats take advantage of the loop wholes in these databases. As discussed earlier in the outline about how this security issue has brought huge problems in the company. Databases are the integral part of the company because it contains a lot of sensitive information about the company and even the information of their clients is stored in these databases. Therefore, their security is of high importance and each company in the market should consider it, as the world is becoming a data oriented.1

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.

The most important functionality that it offers is that it can help create an out-of-band stateful TCP connection between the attacker and the database which can then help us emulate an actual scenario where the system is under attack.

According to David Litchfield, founder of NGS Software "We see it all the time". "It is behind the breach half a million credit card numbers stolen by Russian groups or information from the Drug Enforcement Agency sold to drug runner. This is a documented case of SQL injection does not get the respect it deserves”
