DLL hell is an umbrella term for the complications that arise when one works with dynamic-link libraries (DLLs) used with older Microsoft Windows operating systems, [1] particularly legacy 16-bit editions, which all run in a single memory space.
FIDO uses the concept of TEE in the restricted operating environment for TEEs based on hardware isolation. [13] Only trusted applications running in a TEE have access to the full power of a device's main processor, peripherals, and memory, while hardware isolation protects these from user-installed apps running in a main operating system.
Meltdown exploits a race condition, inherent in the design of many modern CPUs.This occurs between memory access and privilege checking during instruction processing. . Additionally, combined with a cache side-channel attack, this vulnerability allows a process to bypass the normal privilege checks that isolate the exploit process from accessing data belonging to the operating system and other ...
User Interface Privilege Isolation (UIPI) is a technology introduced in Windows Vista and Windows Server 2008 to combat shatter attack exploits. By making use of Mandatory Integrity Control, it prevents processes with a lower "integrity level" (IL) from sending messages to higher IL processes (except for a very specific set of UI messages).
Mandatory Integrity Control is defined using a new access control entry (ACE) type to represent the object's IL in its security descriptor.In Windows, Access Control Lists (ACLs) are used to grant access rights (read, write, and execute permissions) and privileges to users or groups.
In a system with process isolation, limited (controlled) interaction between processes may still be allowed over inter-process communication (IPC) channels such as shared memory, local sockets or Internet sockets. In this scheme, all of the process' memory is isolated from other processes except where the process is allowing input from ...
Confidential computing is a security and privacy-enhancing computational technique focused on protecting data in use.Confidential computing can be used in conjunction with storage and network encryption, which protect data at rest and data in transit respectively.
INTEGRITY-178B is the DO-178B–compliant version of INTEGRITY. It is used in several military jets such as the B-2, [2] F-16, F-22, and F-35, and the commercial aircraft Airbus A380. [3] Its kernel design guarantees bounded computing times by eliminating features such as dynamic memory allocation.
