Number of kernel exploits by year collected by Microsoft This growing trend is evidenced by the data collected by Microsoft threat analysts on the number of known kernel exploits for Windows #What is the most secure web browser for windows software#In most software sandboxes, the kernel attack surface is left unrestricted providing attackers who have achieved code execution within a sandboxed app the opportunity to “escape” and escalate the attack. When sandboxes are in place, malicious code delivered by a successful application exploit is restricted from accessing data and resources on the host operating system, which prevents attacks from performing lateral movement or exfiltrating sensitive information.Īttackers have adapted their tactics rapidly in response to widespread sandboxing by shifting their attention to kernel attacks. Software isolation seeks to contain the damage in the event an application is successfully compromised by an exploit. In recent years, software isolation of commonly attacked applications such as browsers and document readers have become ubiquitous. The ability to refresh the container when a user logs off means malware does not have a place to persist. The WDAG container provides a temporary, contained environment for users to experience the Internet. Doing so provides the highest level of protection against zero-day exploits, unpatched vulnerabilities, and web-based malware. #What is the most secure web browser for windows windows 10#WDAG for Microsoft Edge is the strongest form of isolation today, and now with the recently released Windows 10 version 1709, also known as the Fall Creators Update, users of Windows 10 Enterprise can run the Microsoft Edge browser in a fully isolated hardware environment. WDAG introduces a slimmed down version of the Hyper-V virtualization technology to bring Azure cloud-grade isolation and security segmentation to Windows applications with Microsoft Edge. One example of these kinds of disruptive approaches can be found in Windows Defender Application Guard (WDAG). Some of the most impactful improvements will come by way of attack surface area reduction and architectural change. In Windows 10 we’re not just delivering tit for tat point solutions for the latest attacks instead we’re looking closely at the root causes and are transforming the platform such that we can eradicate entire classes of attacks. The good news is that defenders are also innovating and disrupting long reliable attack methods with new technologies. In response to increased investments in defense, attackers are adapting and improving tactics at breakneck speed. Innovation in the attack space is constant as adversaries increase in both determination and sophistication.
