Presentation Transcript

  1. Introduction • For any business, websites are their digital identity and protection against the top vulnerabilities like XSS is essential • XSS attacks have a wide range of damages • Hackers steal away with crucial & sensitive data present on the website for performing identity theft

  2. What are XSS Attacks? • Cross-site scripting or XSS attacks are security policy which is carried out by the attackers on client-side webpages’ codes • This attack has been in existence for more than 3 decades now • All major websites have been at least once under this vulnerability attack • Attackers use XSS vulnerabilities for stealing user data or controlling the user session • Also used as a component of a major phishing scam

  3. Types of XSS Attacks • Reflected XSS- Also known as non-persistent XSS attack. Here malicious scripts are diverted to another website on the user browser • Stored XSS- Also known as persistent XSS, where malicious code is directly inserted into the web application • DOM XSS- Here the malicious script is present in the Document Object Model rather than the HTML

  4. How XSS Attack Works • XSS attacks are different from other application layer attacks • The application of a user is attacked and not his server • It works by placing a malicious code using a client-side script on the web application’s output • The common motive behind an XSS attack is to gather insights from cookie data • Client-side scripts don’t have direct impact on the server-side information

  5. Preventing XSS Attacks Using a Website Vulnerability Scanner • The website owners can use a website vulnerability scanner when they develop their web applications. • A website scanner tool gives a full audit of security weaknesses along with flaws present in the site • A web security scanner also ensures the user website is also secured against top website vulnerabilities

  6. Preventing XSS Attacks Using an SDL • SDL stands for Security Development Lifecycle • Adding SDL in the web application limits the number of coding errors and security breaches • It ensures that websites become less vulnerable to any XSS attack • SDL assumes that all data received by web application is coming from a non-trustworthy source

  7. Preventing XSS Attacks Having a Crossing Boundaries Policy • A crossing boundary policy allows the authenticated users to enter their login information again before giving access to users for certain pages and services on the website • Crossing boundaries policy can be expanded further so that the session gets terminated if two IP address have similar session data

  8. How VTMScan Helps ESDS VTMScan is a 1-click vulnerability, threat and malware scanner for the user websites and web applications It checks for vulnerabilities like- OWASP Top-10 Vulnerabilities, Cross-Site Scripting (XSS), LFI-RFI Detection, etc. Provides a comprehensive report to the user regarding the vulnerabilities present on his website and web applications
