For example, security features like Windows Defender Device Guard can continue to operate with integrity even if the NT kernel is compromised because it uses VBS to protect the processes that apply code integrity policies to the system. The Security Center which was on Vista has been absorbed in the Action Center. Winlogon is the interactive login manager for Windows based systems. In addition to facilitating encryption, Windows 7 aims to ease compliance requirements related to IT security through new policies and a greater level of detail in security logs.
