Browser security is the application of Internet security to web browsers in order to protect networked data and computer systems from breaches of privacy or malware. Security exploits of browsers often use JavaScript, sometimes with cross-site scripting (XSS)[1] with a secondary payload using Adobe Flash.[2] Security exploits can also take advantage of vulnerabilities (security holes) that are commonly exploited in all browsers (including Google Chrome,[3] Microsoft Internet Explorer,[4] Mozilla Firefox,[5] Opera,[6] and Safari[7]).
