As the amount of digital data grows, so does the theft of sensitive data through the loss or
misplacement of laptops, thumb drives, external hard drives, and other electronic storage …

Traditionally, file systems were implemented as part of OS kernels. However, as complexity
of file systems grew, many new file systems began being developed in user space …

Parallel applications running across thousands of processors must protect themselves from
inevitable system failures. Many applications insulate themselves from failures by …

Secure data deletion is the task of deleting data irrecoverably from a physical medium. In the
digital world, data is not securely deleted by default; instead, many approaches add secure …

Benchmarking is critical when evaluating performance, but is especially difficult for file and
storage systems. Complex interactions between I/O devices, caches, kernel daemons, and …

Laptops are vulnerable to theft, greatly increasing the likelihood of exposing sensitive files.
Unfortunately, storing data in a cryptographic file system does not fully address this problem …

File systems that manage magnetic disks have long recognized the importance of sequential
allocation and large transfer sizes for file data. Fast random access has dominated metadata …

Computer worms—malicious, self-propagating programs—represent a significant threat to
large networks. One possible defense, containment, seeks to limit a worm's spread by …

Methods, media and systems for responding to a Denial of Service (DoS) attack are
provided. In some embodiments, a method includes detecting a DoS attack, migrating one or …

User file systems offer numerous advantages over their in-kernel implementations, such as
ease of development and better system reliability. However, they incur heavy performance …
