Cloud-based reputation checks is performance.
One of the big challenges with cloud-based reputation checks is performance. Users do not typically want to wait a few seconds while the reputation of potential URLs is checked. Most of us have come to expect that websites are at the immediate tips of our fingers and that access and loading of the content should take place rapidly and immediately. This presents a tricky security problem. Since the reputation service exists in the cloud, the challenge can be summed up as, “How can a reputation be securely retrieved without slowing Web access down so much as to create a poor user experience?”
Sample Answer
There are a few ways to securely retrieve a reputation without slowing web access down so much as to create a poor user experience:
- Use a caching mechanism. This means storing the reputation of frequently visited websites on the user’s computer. This way, the reputation does not have to be retrieved from the cloud every time the user visits the website.
- Use a distributed reputation service. This means using a network of servers to distribute the load of reputation checks. This can help to improve performance and scalability.
- Use a lightweight reputation check algorithm. This means using an algorithm that can quickly and efficiently check the reputation of a website.
