IPSec can be used to protect communications between IIS and other servers A+ certificate(http://www.aplus-220-701.com)
that IIS must communicate with and between the administrative workstation and the IIS server. IPSec can also block communications that are not authorized. By requiring an IPSec-negotiated transport for data passed between computers, the confidentiality of the data is protected and the computers with which the IIS server will communicate are restricted. Blocking communications that are not authorized is important because doing so can eliminate attacks based on other protocols. IPSec blocking policy could be set, for example, to block all access except through port 80 (HTTP), port 443 (HTTPS) and, if required, 3389 terminal services. Access can also be controlled by blocking some types of access by specific server.
Two examples of using IPSec are shown in CompTIA A+ Practical Application(http://www.aplus-220-701.com)
. In the first figure, an administrative workstation on the internal network is used to administer an IIS server in the perimeter network. If the administrator workstation attempts ...
... a connection to the IIS server, an IPSec session is negotiated. IPSec policies on the IIS server and on the administrative workstation identify the IP addresses of each other and require certificates for authentication. In the second figure, data requested from the SQL server is returned. Both the request and response are encrypted. In the remote administration example, the data passes through the firewall because appropriate ports are configured.

Follow these guidelines when determining permissions to set for Web sites and virtual directories:
Remove the Read permissions if the entire site uses scripted content.
Do not set Write and Scripts Only permissions or Write and Scripts And
Executables permissions on the same directory.Doing so will allow visitors to add scripts or modify scripts and execute them.
Do not set Write and Script Source Access permissions or Read and Script Source Access permissions on the same directory.Allowing visitors to read
scripts might allow them to read free Microsoft certification exam papers(http://www.examshots.com/vendor/Microsoft-1.html)
sensitive data such as passwords. Allowing visitors to write scripts might allow them to do harm to the data or Web server.
