How can you prevent caching of sensitive data at client or proxies?

How can you prevent caching of sensitive data at client or proxies?

To explain:

1. The cache-control “no-store” option will prevent the request and response from being stored by the cache.
2. Adding the “private” option will prevent proxies from caching the page.
3. The “Back” button can be stopped from showing sensitive data by setting the option “must-re-validate.”

Which of the following would best help to mitigate the risk of sensitive data exposure?

Encrypt data during transport and at rest. Minimize data surface area. Use the latest encrytion algorithms. Disable autocomplete on forms that collect data.

Which of the following is an example of root cause for sensitive data exposure?

Sensitive data exposure occurs as a result of not adequately protecting a database where information is stored. This might be a result of a multitude of things such as weak encryption, no encryption, software flaws, or when someone mistakenly uploads data to an incorrect database.

What’s the best way to cache sensitive data?

If the majority of your traffic is personalized data then you should use HTTPS and rely primarily on browser caches. Make use of this cache by setting Expire header and ETag. Additionally, the Cache-Control: no-store advises browsers to not cache the data on a persistent storage, the data can only be cached on RAM.

What are the best practices for caching in ASP.NET?

Use a sophisticated cachemanager like https://github.com/enyim/memcached-providers; that can have cache-groups. Some data has to be stored for a long time, some short time. Some data has to be stored in ASP.Net cache, etc.

When do you need to use caching in an application?

Caching can also be used to avoid repeating computations while the application is running. If an operation transforms data or performs a complicated calculation, it can save the results of the operation in the cache.

When to use caching to avoid repeating computations?

Caching can also be used to avoid repeating computations while the application is running. If an operation transforms data or performs a complicated calculation, it can save the results of the operation in the cache. If the same calculation is required afterward, the application can simply retrieve the results from the cache.
