When users browse online, they often forget to clear the data from their web browser cache. However, this means that browsers can locally save sensitive website information such as bank account numbers and email passwords. If there is no company practice in place for staff to perform basic security measures like clearing their cache, malware can enter their systems, find private data, and send it to hackers, leading to dire consequences for companies.
How Browser Caches Store Web Data
A cache is a repository of stored data that is used to speed up the process of retrieving data. If a user accessing a resource already has some of its data stored in a cache, then the user does not need to retrieve that data from the resource—he or she can simply use it from the cache. But if the cache is empty, he or she must obtain all of it from the resource, which can be time-consuming.
