Not all applications should be allowed to run in your environment. This episode explores application control mechanisms like whitelisting and sandboxing. You'll learn how whitelisting enforces control by allowing only approved executables, and how sandboxing isolates applications to prevent them from affecting system integrity. We also discuss implementation strategies, policy management, and how to handle exceptions. These controls are especially valuable in high-security or highly regulated environments. CISSPs must understand how to limit application behavior to reduce attack surfaces and contain potential damage.
