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

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.

Our IT department has to place a firewall on the web application such as Mod Security that is free and open sourced this is available for Apache, Microsoft and nginx web servers. This web application firewall will defend the users by catching the SQL injection before they can attack. I will recommend that the IT staff to apply any software patches on the database, so we would minimize the vulnerabilities on the server. Furthermore, they should use SQL variable binding with statements on the web application instead of constructing full SQL queries. Also, minimize the error messages when the student user is logging in with their credentials and get the password wrong then is displays that the password was wrong, but not the username. Above all, this plan will help the Aim Higher college prevent any SQL injection attacks in the future, so the users will feel safe in our when exchanging private data with our school information

Even though there are this kind of attacks. This Microsoft SQL Server has the tools and technologies that mitigate this kind of attacks and there are what am going to talk about.

interface to accomplish the attack motivation behind the database or working framework. It is for the most part because of Web application designers who do not take a strict look at to the SQL statements in the programming procedure. SQL injection attacks are predominantly by building a unique SQL statement, usually a blend of various SQL articulations, they will be passed as parameters submitted to the Web application server to accomplish the desired operation of the invaders by the usage of the server side, for example, getting to passwords and other critical data, getting to the host's control rights et cetera..

Injection through user input: the attackers inject SQL statements by giving reasonably user input. A web application can read user data based on the environment in which application is deployed. This helps the attacker to get the user data directly from them.

Some web developers use “blacklist” of words and characters, but some words like delete and semicolons should be allowed in many types of input. I think the best way to prevent is combination of protection. I would recommend to use SQL parameters. SQL parameters are values that are added to an SQL query at execution time, in a controlled manner. I would use patches and updates in exploited database and application as soon as possible. The firewall should be in place to help to filter out malicious data. Adding new rules regarding SQL injections to firewall will help to detect and patch. Also, use appropriate privileges and keep password hash and encrypted. Password should be change regularly, which overlook most of the time. In addition, I would not display a lot information about database architecture from error messages and use the “Remote Only” custom Errors mode, so external hacker will not get any additional information. After all, SQL injection is most popular tool for hackers to obtain and manipulate data, because it is easy to use. However, combination of the protections can keep secure and monitor

A majority of the software risks are associated with the poor programming practices, such as allowing changed in web page or SQL query structures; unrestricted upload of files; improper handling of operating system commands and log message content; unchecked Uniform Resource Locator (URL) redirection and race condition; inappropriate resource management; and weaker defenses including access control, authentication, encryption, and critical resource allocation porousness (Stallings & Brown, 2012). One of the most popular web application attacks is known as Cross Site Scripting (XSS), where the attacker maligns a vulnerable web page or server. When a user visits the compromised web page, the infected code executes in the browser using the web server privileges. XSS attacks can be of many forms, such as: reflected XSS, where the server directly processes the infected script; persistent XSS, where a stored infected script in the server is passed to the client’s browser and gets stored there; stealing of cookies; defacement of the web pages; phishing; execution of exploits; and violation of privacy (Chugh & Gupta,

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

This paper has been compiled as the final project for the course: Boston University, MET CS 674 – Database Security. This paper contains all relevant material which aligns with the mission of this course – to teach students the tools and techniques required to secure and audit a database system in the information technology era.

In this paper we introduce and expound the SQL Injection attacks. Additionally, we present and discuss two SQL injection detection and prevention techniques in detail. First of which is utilizing query tokenization for tackling against SQL Injection (SQLI) attacks. The second one is a hidden web crawler technique which is an innovative process for discovering SQLI attacks.

Human error: Errors caused by people who get into contact with the web application or data servers either as operators or users include; accidental deletion of data, destruction of software programs, configuration or hardware error. Vulnerabilities left by the software developers in software, is another major error. This can include authentication which can be bypassed, failure to validate input and output data, incorrect implementation of encryption, escalation of privileges, and failure to handle errors correctly can be used to attack web application leading to exposure of sensitive data such as customer’s financial data. This can be used to cause fraud to the customer’s bank or credit card.

There are new SQL Server 2012 security features that Microsoft has provided to their database application program. The research paper will cover the most important features, which can be drilled down into four categories:

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.
