A managed module is a standard 32-bit Microsoft Windows
portable executable (PE32) file or a standard 64-bit Windows portable executable (PE32+) file that
requires the CLR to execute. By the way, managed assemblies always take advantage of Data Execution
Prevention (DEP) and Address Space Layout Randomization (ASLR) in Windows; these two features
improve the security of your whole system.
Data Execution Prevention
Data Execution Prevention (DEP) is a security feature that can
help prevent damage to your computer from viruses and other security threats.
Computer programs set aside a portion of your computer's memory
for data, and another portion for instructions that your programs use. Hackers
can try to trick programs into running (also known as executing) harmful data placed in your computer's memory as
if it were instructions. This could allow a hacker to take control of your
computer.
DEP can help protect your computer by monitoring your programs to
make sure that they use computer memory safely. If DEP notices a program trying
to run instructions from the portion of memory used for data, DEP closes the
program and notifies you.
