A security log is used to track security-related information on a computer system. Examples include: Windows Security Log; Internet Connection Firewall security log; According to Stefan Axelsson, "Most UNIX installations do not run any form of security logging software, mainly because the security logging facilities are expensive in terms of disk storage, processing time, and the cost ...
Apple says that System Integrity Protection is a necessary step to ensure a high level of security. In one of the WWDC developer sessions, Apple engineer Pierre-Olivier Martel described unrestricted root access as one of the remaining weaknesses of the system, saying that "[any] piece of malware is one password or vulnerability away from taking full control of the device".
The system was launched as Mac OS X, renamed OS X from 2012—2016, [10] and then renamed macOS as the current Mac operating system that officially succeeded the classic Mac OS in 2001. The system was originally marketed as simply "version 10" of Mac OS, but it has a history that is largely independent of the classic Mac OS. It is a Unix-based ...
Apple File System was announced at Apple's developers’ conference (WWDC) in June 2016 as a replacement for HFS+, which had been in use since 1998. [11] [12] APFS was released for 64-bit iOS devices on March 27, 2017, with the release of iOS 10.3, and for macOS devices on September 25, 2017, with the release of macOS 10.13.
Intel-based Macs would run a new recompiled version of OS X along with Rosetta, a binary translation layer which enables software compiled for PowerPC Mac OS X to run on Intel Mac OS X machines. [130] The system was included with Mac OS X versions up to version 10.6.8. [131] Apple dropped support for Classic mode on the new Intel Macs.
macOS for Intel supports the NX bit on all CPUs supported by Apple (from Mac OS X 10.4.4 – the first Intel release – onwards). Mac OS X 10.4 only supported NX stack protection. In Mac OS X 10.5, all 64-bit executables have NX stack and heap; W^X protection. This includes x86-64 (Core 2 or later) and 64-bit PowerPC on the G5 Macs.
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.
Hierarchical File System (HFS) is a proprietary file system developed by Apple Inc. for use in computer systems running Mac OS. Originally designed for use on floppy and hard disks , it can also be found on read-only media such as CD-ROMs .
