A 2007 paper from Hebrew University suggested security problems in the Windows 2000 implementation of CryptGenRandom (assuming the attacker has control of the machine). Microsoft later acknowledged that the same problems exist in Windows XP, but not in Vista. Microsoft released a fix for the bug with Windows XP Service Pack 3 in mid-2008. [2]
Microsoft codenames are given by Microsoft to products it has in development before these products are given the names by which they appear on store shelves. Many of these products (new versions of Windows in particular) are of major significance to the IT community, and so the terms are often widely used in discussions before the official release.
The paper's conclusions were based on disassembly of the code in Windows 2000, but according to Microsoft applied to Windows XP as well. [6] Microsoft has stated that the problems described in the paper have been addressed in subsequent releases of Windows, which use a different RNG implementation.
Windows XP has been criticized for its vulnerabilities due to buffer overflows and its susceptibility to malware such as viruses, trojan horses, and worms.Nicholas Petreley for The Register notes that "Windows XP was the first version of Windows to reflect a serious effort to isolate users from the system, so that users each have their own private files and limited system privileges."
Windows File Protection (WFP), a sub-system included in Microsoft Windows operating systems of the Windows 2000 and Windows XP era, aims to prevent programs from replacing critical Windows system files. Protecting core system files mitigates problems such as DLL hell with programs and the operating system.
In Windows XP, Windows Server 2003, and Windows Server 2003 R2, after a grace period of 30 days, the operating system cannot be used at all until the activation process is completed successfully. [12] [13] In Windows Vista RTM, after a grace period of 30 days, the operating system will boot only into a reduced functionality mode. The reduced ...
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
All versions from Windows 3.0 to Windows Server 2003 R2 contain this security flaw. [2] However, Windows NT 4.0 and Windows XP, unless patched, are more vulnerable than earlier versions because their default installation enables Windows Metafile code execution, the source of the vulnerability. [3] Later versions of Windows do not have this ...
