CPSC 420 Chapter Notes - Chapter Chapter 9: Antivirus Software, Attack Surface, Port Scanner
Document Summary
When developing a web application, it is important to consider the perpetual variance in user machines. This includes taking into account different screen sizes, browsers, and devices. Additionally, it is important to consider compatibility issues and how to accommodate users with different levels of access. For example, some users may not have javascript enabled, or may be using an older browser version. The web is a living network which is constantly evolving new and improved threats to your operating system. Foremost, installing patches to your browser can substantially reduce the attack surface of a web application by mitigating (or completely eliminating) old vulnerabilities associated with outdated browsers. Secondly, updating commonly used plug-ins, and eliminating unused plug-ins, will decrease the number of open vulnerabilities a hacker or malicious software might exploit. Summarize the risks of using javascript in a web application from a security perspective.
