Samhain is an integrity checker and host intrusion detection system that can be used on single hosts as well as large, UNIX-based networks. It supports central monitoring as well as powerful (and new) stealth features to run undetected in memory, using steganography.
Memory scrubbing consists of reading from each computer memory location, correcting bit errors (if any) with an error-correcting code , and writing the corrected data back to the same location. [ 1 ] Due to the high integration density of modern computer memory chips , the individual memory cell structures became small enough to be vulnerable ...
An attempt to access unauthorized [a] memory results in a hardware fault, e.g., a segmentation fault, storage violation exception, generally causing abnormal termination of the offending process. Memory protection for computer security includes additional techniques such as address space layout randomization and executable-space protection.
F2FS uses the checkpoint scheme to maintain file system integrity. At mount time, F2FS first tries to find the last valid checkpoint data by scanning the CP area. In order to reduce the scanning time, F2FS uses only two copies of the CP. One of them always indicates the last valid data, which is called a shadow copy mechanism.
This allows user-level code to allocate private regions of memory, called enclaves, which are designed to be protected from processes running at higher privilege levels. [ 1 ] [ 2 ] [ 3 ] A TEE as an isolated execution environment provides security features such as isolated execution, integrity of applications executing with the TEE, and ...
By David Shepardson. WASHINGTON (Reuters) -The U.S. House of Representatives is set to vote next week on an annual defense bill that includes just over $3 billion for U.S. telecom companies to ...
Control-flow integrity (CFI) is a general term for computer security techniques that prevent a wide variety of malware attacks from redirecting the flow of execution (the control flow) of a program. Background
The Information reported that the Huawei-led consortium had built at least two HBM production lines, using memory chips from different companies, in a form of internal competition.
