Essay On Web Application Attack

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

This type of attack is usually used for bringing down the systems at once by constantly sending massive amount of URL requests or overloading the server’s network traffic with bogus information. This is purposefully done to either a user’s system or the whole network to interrupt it partially or render it completely useless. When the system is brought down to its knees, the crackers either transform the complete system/website or do some manipulate some particular component to benefit from

Next is Denial of Service. According to Conklin, White, Williams, Davis, and Cothren (2012), a Denial of Service (DoS) attack is an attack intended to disrupt a system or service from operating normally. The attacker will attempt, through means of crashing the system, closing out a logged on session, or overwhelming a machine with multiple

In order to overcome all these problems I will suggest IBM mail servers which have all these features. The company can face a big problem if a new version released, the up gradation of the software

Web application vulnerabilities account for the largest portion of attacks outside of malware. It is crucial that any web application be tested for vulnerabilities and any issues be fixed prior to production deployment.

System/application attacks fall within three categories: denial or destruction, alteration, and disclosure. This paper will cover some common system/application domain vulnerabilities: unauthorized physical and logical access to resources, weaknesses in server operating system and application software, and data loss.

Denial of Service (DoS) attack is a very common cyber menace that renders websites and other online means inaccessible to intended users. There are various types of DoS threats and nearly all directly target the core server structure. Others abuse weaknesses in application and communication proprieties. DoS is also used as a cover-up for other wicked actions, and to take down security applications like web firewalls. A prosperous DoS attack is very obvious and impacts the entire online user base.

Injection Attacks where the attacker deposits the scripts into a web request to execute at the client-end (Wadlow, 2009).

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.

Also, it is very difficult to track the origin of attack and to know that an attack has happened. The attack can be found when the user contacts the site after the attack or if the website occasionally checks for some miscellaneous code in their database.

Denial-of-service is an attack aimed to refuse access for legitimate users and disrupt service availability according to www.msdn.microsoft.com. This type of security threat according to www.tech.co.uk is rapidly increasing on the Internet due to open doors on Websites. By using the Internet, companies increase the risk of denial of service attack. Denial of service can also be caused by too many connected to a server at the same making run slow or unavailable to others. People who deliberately abuse a network server are often difficult to track down.

Distributed denial of service is hard to block. Due to much traffic, system could not tolerate the unacceptable requests from different machines. A single user is attacked from the number of attackers. The millions of requests force the computer to shut down. The main purpose of denial of service is to disturb business of specific organization. The normal work is effected such as make server unavailable to its regular users. A single blockage of an IP address could not stop the attack.

In today’s highly connected digital ecosystem, our lives, businesses, communications, and a lot of activities depend on the websites and web applications. All websites contain sensitive data and deliver business-critical information services to the targeted audience. Due to the rapidly increasing use of websites and web applications, vulnerabilities have become quite rampant. Even the smallest security loophole can give cybercriminals a chance to destroy the web-based business, damage customer confidence, and brand reputation in a short time span.

In recent years many types of work is done by web application. Web application plays imperative function in recent years. But now a days hacker can freely ingress web application by using many type of techniques. So it’s mean that web application visualize different kind of security threats. But Sql injection is one of the top most bad attack techniques in the web application. This type of techniques sanction the hacker to gain information to organization database. Attacker dripped the information in online transaction, online banking, paper , mail etc. Data and information is very vital issue in organization, business and industries. Now a days attacker can expose freely of all the sensitive information in database. So
