Cross-site scripting

A vast array of techniques is implemented to counter the cross site scripting attacks (XSS) that only seems to increase in number and complexity day by day. However, all the prevention practices to avert the XSS attacks can be classified based upon the place it is deployed. Validation checks can be setup at server-side, client-side or at both end points. 1. Server Side Validation: Before any data is passed to the server or the database, it needs to be systematically checked and validated to reduce

associated security threats also grow. Two of the most common, and dangerous, threats to web applications are Cross-Site Request Forgery (CSRF) and Cross-Site Scripting (CSS); in fact, both threats appear in the 2013 OWASP Top 10 list of critical security risks. Understanding the threat of CSRF and CSS is essential to reducing the risk faced by users and developers of web applications. CSRF Cross-Site Request Forgery (CSRF) is an attack technique that exploits browser and HTTP weaknesses to send unauthorized

Some types of web application flaws are mostly caused by an attack, a threat or a weakness. To present these security vulnerabilities, I have taken into consideration the results from OWASP (Open Web Application Security Project) organization, which is focused on improving the security of software. According to OWASP, top 10 most dangerous web vulnerabilities are listed below. • Injection Flaws Injection flaws, such as SQL, OS, and LDAP injection, allow attackers to relay malicious code through

INTRODUCTION Wireless networking has numerous benefits. Productivity remarkably enhances due to the higher accessibility to the information resource. Network configuration as well as reconfiguration becomes easier, quicker, and overall less expensive. Nonetheless, this technology also poses new threats as well as brings change in the already existing profile of risk in the information security. Explaining this terminology, as we all know that the communication occurs "through the air" utilizing

results for and to that user, without properly sanitizing the request [17]. A common example of a potential vector is a site search engine where user searches for a string and the search string will typically be redisplayed verbatim on the result page to indicate what was searched for. If this response does not properly escape or reject HTML control characters, a cross-site scripting flaw will ensue

in order to defend against malicious app upload (i.e.) everything was functioning properly until the defence mechanism got revealed by the Finger printing attack by two security researchers in order to understand the security of the bouncer. Cross site scripting is one of the most frequent cyber-attacks and it ranked number three in the OWASP top ten for the current year (2013), it is very simple to trick the user to click on a malicious link the attacker has even more advantage if the user is browsing

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

This report documents the results from the penetration test of the Ernst and Young Credit Union external website (http://10.55.3.101). Full authorisation has been given to conduct the test, which was carried out in a manner that simulates an attack from a malicious user. The objectives were to: - establish if a remote attacker could penetrate the security mechanisms of the Ernst & Young Credit Union. -evaluate the impact of such a breach on the security of confidential information and on the infrastructure

Using the internet has become an everyday task for many people in their day to day lives but they don’t think about the risk that could come with it. When people hear the words youtube, twitter, pinterest or even craigslist they don’t think about the systems running these programs. When individuals use these social media platforms or web based apps on their phones or computers often they’re not thinking about the big picture web 2.0 running all these websites and web based applications. Individuals

OpenID is a decentralized, single sign-on authentication system for internet sites that require authentication for use. It was developed out of the need to create a different, easier and more secure, type of authentication system than using a password. OpenID was developed using the open source software model to be an interoperable protocol independent from any single organization OpenID allows users to log into websites with one single ID, instead of the user having to create and manage multiple
