The NTFS File System
The NTFS File System OVERVIEW: This lab is part of a series of lab exercises intended to support courseware for Forensics training. The development of this document is funded by the Department of Labor (DOL) Trade Adjustment Assistance Community College and Career Training (TAACCCT) Grant No. TC-22525-11-60-A-48. In this lab, students will enumerate hosts on the network using various tools. This lab includes the following tasks: 1 – Examining the NTFS File System 2 – Using a HEX Editor to explore an NTFS Partition 3 – Verifying and viewing the image details 4 – Analyzing an NTFS Partition With Autopsy Key TermDescription The acronym NTFS stands for New Technology File System. The NTFS File System was originally introduced with the Windows NT. NTFS is a journaling file system which means it keeps a log of changes being written to the disk. If a computer is shutdown improperly, it will have a better NTFS chance of recovery if it has a journaling file system. Files and folder access can be restricted with the security feature of NTFS. Starting with Windows 2000, Microsoft included the Encrypted File System, or EFS, as an NTFS feature. EFS allows users to encrypt files to protect against unauthorized access. A Feature of the NTFS File system that allows you to encrypt files and folders. The feature EFS became available on the NTFS File system starting with Windows 2000, and is still available today on Windows 10 and Server 2016. An Alternate Data Stream, or ADS, is a feature of the NTFS file system that allowed compatibility ADS with older versions of the Mac OS. -
Mac Keyboard Shortcuts Cut, Copy, Paste, and Other Common Shortcuts
Mac keyboard shortcuts By pressing a combination of keys, you can do things that normally need a mouse, trackpad, or other input device. To use a keyboard shortcut, hold down one or more modifier keys while pressing the last key of the shortcut. For example, to use the shortcut Command-C (copy), hold down Command, press C, then release both keys. Mac menus and keyboards often use symbols for certain keys, including the modifier keys: Command ⌘ Option ⌥ Caps Lock ⇪ Shift ⇧ Control ⌃ Fn If you're using a keyboard made for Windows PCs, use the Alt key instead of Option, and the Windows logo key instead of Command. Some Mac keyboards and shortcuts use special keys in the top row, which include icons for volume, display brightness, and other functions. Press the icon key to perform that function, or combine it with the Fn key to use it as an F1, F2, F3, or other standard function key. To learn more shortcuts, check the menus of the app you're using. Every app can have its own shortcuts, and shortcuts that work in one app may not work in another. Cut, copy, paste, and other common shortcuts Shortcut Description Command-X Cut: Remove the selected item and copy it to the Clipboard. Command-C Copy the selected item to the Clipboard. This also works for files in the Finder. Command-V Paste the contents of the Clipboard into the current document or app. This also works for files in the Finder. Command-Z Undo the previous command. You can then press Command-Shift-Z to Redo, reversing the undo command. -
MULTIPLE ACCUDRAW SHORTCUT FILES by Seth M
MULTIPLE ACCUDRAW SHORTCUT FILES By Seth M. Cohen, ProSoft NET Is your MicroStation desktop cluttered with toolframes & toolbars? Are you sacrificing precious desktop real estate because “YOU GOTTA HAVE THAT ICON”? If so, then creating multiple AccuDraw key-in shortcuts will let you reclaim your desktop! What is AccuDraw? According to the MicroStation/J help, “AccuDraw is a drafting aid that evaluates such parameters as your current pointer location, the previously entered data point, the last coordinate directive, the current tool's needs, and any directive you have entered via either keyboard shortcuts or AccuDraw options. AccuDraw then generates the appropriate precision coordinates and applies them to the active tool”. The topic that we will be discussing is AccuDraw shortcuts. ACCUDRAW SHORTCUTS The functionality of AccuDraw shortcuts is to run MicroStation key-in commands. This is accomplished by the user creating a shortcut to a desired key-in by associating two alphanumeric characters to that key-in. Here is an example of how to create an AccuDraw shortcut, and how they can make drafting more efficient, and increase your MicroStation desktop. Wouldn’t it be nice if…….you could turn off the display of, let’s say, 150 reference files without having to: 1) Open the Reference File Dialog box 2) Select all the reference files 3) Click the display toggle on the Reference File Dialog to off 4) Click the Update All icon to refresh the view Well with AccuDraw, you could set two shortcuts to toggle all the reference files on and off. Here’s how: First, we will define two shortcuts that will act like switches. -

Startup Keyboard Shortcuts Press the Key Or Key Combination Until The
Startup keyboard shortcuts Press the key or key combination until the expected function occurs/appears (for example, hold Option during startup until Startup Manager appears, or Shift until "Safe Boot" appears). Tip: If a startup function doesn't work and you use a third-party keyboard, connect an Apple keyboard and try again. Key or key combination What it does Option Display all bootable volumes (Startup Manager) Shift Perform Safe Boot (start up in Safe Mode) C Start from a bootable disc (DVD, CD) T Start in FireWire target disk mode N Start from NetBoot server X Force Mac OS X startup (if non-Mac OS X startup volumes are present) Command-V Start in Verbose Mode Command-S Start in Single User Mode To use a keyboard shortcut, or key combination, you press a modifier key with a character key. For example, pressing the Command key (the key with a symbol) and the "c" key at the same time copies whatever is currently selected (text, graphics, and so forth) into the Clipboard. This is also known as the Command-C key combination (or keyboard shortcut). A modifier key is a part of many key combinations. A modifier key alters the way other keystrokes or mouse clicks are interpreted by Mac OS X. Modifier keys include: Command, Control, Option, Shift, Caps Lock, and the fn key (if your keyboard has a fn key). Here are the modifier key symbols you can see in Mac OS X menus: (Command key) - On some Apple keyboards, this key also has an Apple logo ( ) (Control key) (Option key) - "Alt" may also appear on this key (Shift key) (Caps Lock) - Toggles Caps Lock on or off fn (Function key) Startup keyboard shortcuts Press the key or key combination until the expected function occurs/appears (for example, hold Option during startup until Startup Manager appears, or Shift until "Safe Boot" appears). -

Get Your Default KDE and GNOME Desktops in Line by David D
Get Your Default KDE and GNOME Desktops in Line by David D. Scribner As mentioned in my last article, Get Your Default KDE and GNOME Menus in Line, the User Manuals for the KDE and GNOME GUI environments include instructions on modifying the user’s menus and desktop properties. Just as with the menus however, modifications to the desktop settings made by individual users are stored in the user’s home directory and have no affect on the “defaults” installed for new users. Being the system administrator, you may have custom desktop wallpaper, shortcut icons and panel (or Kicker, as KDE now calls it) icons that differ from those set up in the default configurations. If you wish to have the default desktops installed for new users tailored to include selected application icons in the panel or kicker (taskbar), or changes to the default desktop shortcuts, background, colors or style that GNOME and KDE normally set up for those new users, you will have to make a few modifications. This article is intended to cover the basic tasks of customizing such default installations. Since customizing the default desktops for your new users result in changes to the installed files, back up any of these files/directories before proceeding with any modifications! Desktop Configuration Skeletons Items pertaining to the desktop you want your new users to be greeted with are perhaps easiest to configure by placing the relevant KDE and GNOME desktop configuration files in the /etc/skel directory. You could modify the master files KDE and GNOME use to create new user setups, but they may be overwritten should you upgrade to a newer version of the environment. -
