While it's always a good idea to take steps to protect your online accounts and sensitive information, there may not be a foolproof way to completely prevent cookie and session theft. However, there are some steps you can take to minimize the risk.
Firstly, it's important to keep your browser and operating system up-to-date with the latest security patches. This helps to protect against known vulnerabilities that could be exploited by attackers.
Another important step is to use strong, unique passwords for each of your accounts and to enable two-factor authentication wherever possible. This makes it much more difficult for attackers to gain access to your accounts, even if they do manage to steal your cookies or sessions.
As for the specific question about using Brave's "Intrusion Prevention" component to protect your cookies and sessions, it's difficult to say without more information about how exactly the component works and where Brave stores its sessions and cookies. However, it's worth noting that there is always a trade-off between security and convenience, and blocking access to certain folders could potentially cause issues with Brave's functionality.
