Which type of memory is less secure due to remote access capabilities?

RAM
ROM
Virtual Storage
Cache Memory

The correct answer is: Virtual Storage

Virtual storage refers to a memory management capability that allows for the creation of an abstraction layer over physical memory, enabling systems to use disk storage to extend available memory. This type of storage can make data accessible over a network, making it less secure. Since data stored in virtual storage can be remotely accessed by different users and applications via network protocols, there is a heightened risk of unauthorized access or data breaches, which is a concern when considering security. In contrast, other types of memory such as RAM, ROM, and cache memory typically operate within the confines of the physical hardware or local machine and do not have the same level of remote access capabilities. This makes them inherently more secure against remote attacks. ROM, for instance, is read-only and is not meant to be modified or accessed remotely, while RAM and cache are used for immediate data processing and do not store data for external access.
