Types of Web Application Flaws

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

It is not uncommon to find various organizations complaining about security flaws in their information systems. Failing to prevent or mitigate the security flaws may lead to system breakdown, errors, and loss of crucial information. This is why it is important for users of information systems to find the right solutions that can help counter and mitigate security flaws. One common problem with security flaws connected with information systems or networks is that the security flaws occur in multiples. Technological advances have, fortunately, made it possible for people and organizations to prevent and detect such security flaws using security strategies. Layered Security and Defense in Depth are two strategies that can help prevent attacks and protect information systems against security flaws. The two strategies are similar but are based on completely two different concepts. This paper compares and contrasts the Layered Security and Defense in Depth Strategies by explaining how each of the two functions. Additionally, the paper includes an explanation about the advantages and disadvantages of the two strategies.

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

If we turn the clock backwards about 10 or 15 years, we find that people do not care much for the security of the web due to the lack of trying to exploit web applications for personal interests. But more recently, the issues related to the security of the Web began to grow, but unfortunately, there are many Web applications that have been developed, but these applications are started without any design for security.

Web application security is a form of security that deals specifically with the security of websites, their applications and web services. At advanced levels, web application security touches on the principles of web application security but applies them directly to Internet and Web systems.

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.

Security flaws or vulnerabilities have increased and spread rapidly over the past several years. More and more vulnerabilities are being discovered by security experts worldwide. Some of these flaws have proved to be extremely dangerous and lethal as they have caused unmeasurable damages to industries and organizations as well as individual users. Security vulnerability can be identified as a fault or weakness in a product or system that allows an attacker to exploit and manipulate that particular vulnerability and compromise the confidentiality, integrity and availability of that product or system (Definition of a Security Vulnerability ).

The Server-Side Includes attack allows the exploitation of a web application by injecting scripts in HTML pages or executing arbitrary codes remotely. It can be exploited through manipulation of SSI in use in the application or force its use through user input fields. The attacker can access sensitive information, such as password files, and execute shell commands. The SSI directives are injected in input fields and they are sent to the web server. The web server parses and executes the directives before supplying the page. Then, the attack result will be viewable the next time that the page is loaded for the user's browser.

Is a program which communicates with a web application through the web front-end in order to identify potential security vulnerabilities in the web application and architectural

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.

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.

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.

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.

The greatest area of vulnerability and potential for damage or data loss of web applications and

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.
