USE SYSKEY ON WINDOWS 7 TO ENCRYPT THE SAM TO HARDENING SYSTEM Very few netbook computers support BitLocker, which means that they are Date: 25/10/2013 vulnerable to utilities that allow you to boot from a USB device and reset the local Source: LINK Permalink: LINK administrator password. The way to ensure that this type of attack doesn’t work is Document Version: 1.0 to use SYSKEY to encrypt the SAM database. Total Chars: 1937 Total Words: 369 Created by: HeelpBook Page: 1 Obviously this solution can be used even on laptops and desktop computers. SYSKEY is a tool that has been around for some time on Windows client operating systems, but most administrators don’t bother using it because it makes recovering a computer difficult in the event that auser forgets their password. In some cases you want to do all that you can do to protect the data on a netbook computer. To do this, you should use SYSKEY to encrypt the SAM database and use EFS to encrypt any locally stored files and folders. To accomplish this, perform the following steps: Log on to Windows 7 with an account that has local administrator access. Type SYSKEY into the textbox on the start menu. Click OK at the UAC prompt. Select the Encryption Enabled Option. Select the Password Startup Option. Enter the Startup Password that must be entered each time. Reboot the computer. From now on the Startup Password must be entered to unlock the SAM database before local logon will be allowed.

C2 Security Evaluation vs. Certification Setting up a C2-compliant System Abstract Microsoft® Windows NT® operating system provides a rich set of security features. However, the default out-of-the-box configuration is highly relaxed, especially on the Workstation product. This is because the operating system is sold as a shrink-wrapped product with an assumption that an average customer may not want to worry about a highly restrained but secure system on their desktop. This assumption has changed over the years as Windows NT gains popularity largely because of its security features. Microsoft is investigating a better secured default configuration for future releases. In the meantime, this white paper talks about various security issues with respect to configuring all Windows NT version 4.0 OS products for a highly secure computing environment.

Syskey Password Cracker Software Free Download Syskey.Exe Utility Is No Longer Supported in Windows 10, Windows Server 2016, and Later Versions
syskey password cracker software free download Syskey.exe utility is no longer supported in Windows 10, Windows Server 2016, and later versions. Windows 10, version 1709, Windows Server, version 2004 and later versions of Windows no longer support the syskey.exe utility. Applies to: Windows 10 - all editions, Windows Server 2019, Windows Server 2016 Original KB number: 4025993. Changes detail. The following changes are made: The syskey.exe utility is no longer included in Windows. Windows will never prompt for a syskey password during startup. Windows will no longer support installing an Active Directory domain controller by using Install-From-Media (IFM) that was externally encrypted by the syskey.exe utility. If an operating system (OS) was externally encrypted by the syskey.exe utility, you can't upgrade it to Windows 10 version 1709, Windows Server version 2004, or a later version of Windows. Workaround. If you want to use boot-time OS security, we recommend that you use BitLocker or similar technologies instead of the syskey.exe utility. If you use Active Directory IFM media to install replica Active Directory domain controllers, we recommend that you use BitLocker or other file encryption utilities to protect all IFM media. To upgrade an OS that's externally encrypted by the syskey.exe utility to Windows 10 RS3 or Windows Server 2016 RS3, the OS should be configured not to use an external syskey password. For more information, see step 5 in How to use the SysKey utility to secure the Windows Security Accounts Manager database. More information. Syskey is a Windows internal root encryption key that's used to encrypt other sensitive OS state data, such as user account password hashes.

Advantages and Disadvantages of EFS and Effective Recovery of Encrypted Data Whitepaper

One of the innovations in the Microsoft Windows 2000 and the NTFS 5.0 file system was the Encrypting File System (EFS) technology, which is designed to quickly encrypt files on the com- puter hard drive. NTFS by itself has built-in protection. However, as is frequently the case, it very quickly required additional security. The reason was the wide-spread use of NTFSDos-type utilities, which made it easy to circumvent the NTFS security system, gaining access to it through DOS, thus ignoring the set access rights. The EFS system uses both public and private key encryption and CryptoAPI architecture. EFS can use any symmetrical file encryption algorithm from the following list: Microsoft Windows 2000 used DESX, Windows XP used 3DES, and Windows XP SP1, 2003 and the new Windows Vista use AES. File encryption does not require the user to execute any preliminary operations. During the first encryption of the file, an encryption certificate and a private key are automatically issued for the user. One of the distinguishing convenient features of EFS is that the files remain encrypted when they are transferred to a different folder or to a different NTFS drive.

Review NTFS Basics
Australian Journal of Basic and Applied Sciences, 6(7): 325-338, 2012 ISSN 1991-8178 Review NTFS Basics Behzad Mahjour Shafiei, Farshid Iranmanesh, Fariborz Iranmanesh Bardsir Branch, Islamic Azad University, Bardsir, Iran Abstract: The Windows NT file system (NTFS) provides a combination of performance, reliability, and compatibility not found in the FAT file system. It is designed to quickly perform standard file operations such as read, write, and search - and even advanced operations such as file-system recovery - on very large hard disks. Key words: Format, NTFS, Volume, Fat, Partition INTRODUCTION Formatting a volume with the NTFS file system results in the creation of several system files and the Master File Table (MFT), which contains information about all the files and folders on the NTFS volume. The first information on an NTFS volume is the Partition Boot Sector, which starts at sector 0 and can be up to 16 sectors long. The first file on an NTFS volume is the Master File Table (MFT). The following figure illustrates the layout of an NTFS volume when formatting has finished. Fig. 5-1: Formatted NTFS Volume. This chapter covers information about NTFS. Topics covered are listed below: NTFS Partition Boot Sector NTFS Master File Table (MFT) NTFS File Types NTFS File Attributes NTFS System Files NTFS Multiple Data Streams NTFS Compressed Files NTFS & EFS Encrypted Files . Using EFS . EFS Internals . $EFS Attribute . Issues with EFS NTFS Sparse Files NTFS Data Integrity and Recoverability The NTFS file system includes security features required for file servers and high-end personal computers in a corporate environment.

SOLUTION: “This Is Microsoft Support” Telephone Scam – Computer Ransom Lockout
SOLUTION: “This is Microsoft Support” telephone scam – Computer ransom lockout Posted on April 10, 2013 A trend of the past couple of years has been for scammers to contact computer owners directly via telephone in the United States in an effort to convince them that there is a problem with their PC and they’ll need to pay to have it fixed. In general, these people cannot fix anything, and instead they merely charge exorbitant fees for absolutely nothing. In other words, they scam you. The call generally goes something like this: 1. A foreigner with a thick Indian accent identifies himself as a member of Microsoft Support or similar. 2. He informs you that you have a number of critical problems with your PC and that you will need to have it fixed. 3. To convince you, he offers to connect remotely and pulls up your Event Log (eventvwr.msc). He then filters for Warnings, Errors, and Critical events and uses that as evidence that your PC will soon fail to work correctly if you do not pay him to correct it. The astute among you have probably already sensed that something here is seriously wrong, and it’s not your PC. It’s the fact that someone is calling you to tell you there is a problem with your computer. No one will ever do that. The only way they could possibly know there is a problem is by hacking or guessing. In this case, it’s mere guesswork, and it’s not even correct most of the time.
