Designing for Security
Feeling safe, open and secure are important elements of secure design.
Application development can pose challenges such as handling errors, exceptions,
and variables that may arise. If an exception is thrown, it needs to be
addressed appropriately. "Failsafe" blocks access when the system is unavailable
or inconsistent, ensuring access is granted only to the right owner in an
appropriate manner. "FailSecure" is a bit different, blocking access entirely
when the system is unavailable or inconsistent.
When it comes to "FailSafe," it's about minimizing damage in case of system
failure, such as handling incomplete transactions. For "FailSecure," it's a new
way of dealing with the right owners, ensuring that access is granted to the
right ones only. It's crucial to know how to handle failures, power outages, and
other issues to ensure the right thing is done.
Finding a Balance
We want the system to overlook minor issues or mistakes, veering towards
permissiveness, while avoiding accidentally shutting the whole system down.
Functionality should be available and executed when intended, leaving the right
switches and openings open. It's crucial to leave some options available if a
failure occurs.
Addressing Specifics
It's important to consider specific functions and mechanisms while ensuring that
functions are available when we need to execute them. It's also crucial to
address the importance of addressing specific functions mechanisms. Lastly,
consider controlling a function or process and terminating it if necessary.
Monitoring functions and processes should also be a priority.
