Endpoint protection products are designed to protect against remote attacks through continuous monitoring or isolation of the network traffic and protected operating system/applications using a software agent installed on the host operating system. Given that most endpoint protection products are designed to protect laptop and desktop clients and client applications rather than servers/server applications, NSS tests endpoint protection products by attempting to compromise client applications using “target initiated” exploits, including those against web browsers such as Microsoft Internet Explorer and Mozilla Firefox; email clients such as Microsoft Outlook, Mozilla Thunderbird, and Lotus Notes; desktop publishing and office productivity tools such as Adobe Acrobat, Microsoft Word, PowerPoint, and Excel; and media players such as Windows Media Player, Apple QuickTime, and Real Audio/Video.
