In order to take a more proactive stance against malicious users and attackers, IIS is installed in a highly secure and locked mode. Requests for Dynamic Content Return 404 Error This alternative, however, still presents a security risk because the TCB permission is very powerful.įor more information, see Configuring Worker Process Identities and IIS and Built-in Accounts in the Help that comes with IIS Manager. As an alternative, and if your application needs permission to use the Trusted Computing Base (TCB), run the application as a configurable identity and assign the TCB permission to the configurable identity. If it is absolutely necessary to use the LocalSystem account on an application, run that application in a new application pool in its own virtual directory so you can reduce the attack surface by isolating the application. You should avoid using the LocalSystem account when possible.
The LocalSystem account has access to almost all resources on the operating system, and therefore creates serious security implications. If you migrate applications to IIS 6.0 while the server is in worker process isolation mode, and if your applications previously ran in-process (in Inetinfo.exe) as LocalSystem, the applications may fail to access resources because of the restrictions set forth by the Network Service identity. Network Service is an account with few user rights and therefore provides better security by restricting access to resources on the Web server. Applications running in this mode use the Network Service identity, by default.
