    How to harden your computer:

    Post by Rex31056 on Sat Oct 12, 2013 2:48 am

    LIST:

    Know

    -How to delete a user.

    -How to check the properties of files on the desktop icons. You never know what you can find!

    -How to pay attention to you virtual surroundings!

    -How to Watch out for malicious files (like Mine craft) !!!

    -How to watch out for registry errors.

    -How to access: http://support.microsoft.com/kb/136393

    WHEN IN COMPETITION

    -If you can’t click an icon on the desktop, make sure the background is not trolling you!!!

    -Check the properties of files. (Check the file paths)

    -Never trust a program you do not recognize!

    -Delete the bad .bats

    -Tools>FolderOptions>ShowHiddenFolders

    -Delete “Bad Guy” Users (Ec: Abstergo)

    -Use Task Manager to stop suspicious services.

    -BTW, NEVER DELETE SERVICES FROM THE SYSTEM!

    -Go to admin tools in the control panel

    -Never make suspicious users administrator.

    -Right click in My Computer and disable remote desktop.

    -Best way to complete tasks:

    1.) Go to Control Panel

    2.) Make the view in icons

    3.) Select admin. Tools

    - Make sure your Drive isn’t shared to the network.

    -Uninstall some useless programs.

    -Go to security center.

    -Download AntiVirus at some point in the competition.

    -Windows Defender is an antivirus program.
    END DOC*

    Not sure what will not be and will be in the competition but it seems the stuff we covered in class would be important so we should just go in depth on that type of stuff. (access control, user privileges, firewall, networking) I think they also said it was point-based so prioritize working on any clues we’re given first. Remember to check properties of applications for clues and suspicious activity.

    -Physical Security

    * Use BIOS (Basic Input and Output System) to disable booting from external devices

    * Set password to protect these (optional)

    * Full disk encryption using bitlocker if we can use internet

    * Difficult passwords should be made (15+ characters)

    * UPDATE COMPUTER

    * Uninstall unnecessary applications

    -Access Control

    * Disable or remove non-user accounts (start-> search bar-> run -> lusrmgr.msc or navigate through admin tools)

    * Verify administrator and guest accounts are disabled (should be default on windows 7)

    * Reset main account password to be difficult

    * Check shared files/drives

    * Download antivirus if internet is available in competition

    * Disable unused protocols

    * Gpedit.msc in run to set up software restriction policies

    -Network Control

    * Disable IPv6 if IPv4 is available

    COMPUTER CONFIGURATION HAS A LOT OF THINGS

    A short warning

    Post by NightWind on Wed Oct 16, 2013 8:43 am

    When accessing hidden folders,DO NOT TOUCH ANYTHING IF YOU DON'T KNOW WHAT YOU ARE DOING!
    This includes Program Data folder,AppData folder(which has Sun Microsystems Java VM files),and GUEST folder.
    Deleting or modifying these without proper knowledge will RUIN your computer.
    Also if you're not sure if it's bad .bat file or not,DO NOT OPEN IT.
    Instead,open up Notepad,drag that file into the screen,and see if there's some baddies inside the code.
    This includes "Flood" virus,"Win32.Melt" virus,"Death.bat" virus and BatchVBSFusion (Visual Basic and Batch fusion) viruses.
    If there's something related to deleting or overwriting,moving,opening files or folders,it's suspicious file.
    Also Flood and Melt virus has this algorithm: (simplified for non-programmer users)
    Code:
    Start
    Do "something"
    Blah
    Blah
    Blah
    .
    .
    .
    goto Start
    Also it is advised NOT to click on Download button in some sites like FileHippo,4Shared,Dropbox,Box,CrackInn.org,or any unknown sites.
    LOOKY HERE:
    Except for ThePirateBay,there's NO VIRUSES.

    You can literally SCREW UP your computer if you mistreat BIOS(Basic Input & Output System)!
    DO NOT TOUCH fan speed(called FAN PWM),S.M.A.R.T on Foxconn(America Megatrends BIOS,so-called AMIBIOS),CPU Clock,Serial ATA(SATA) connection settings and Parallel ATA(PATA) drive settings,Video driver settings(forced),and most importantly,POWER SAVING FEATURES.
    Just go to a page related to "Boot Sequence" and change order,CD Drive goes to top,HDD goes to middle,and external devices goes to bottom.
    If you're unsure if it's CD-ROM drive or HDD,check the code on the left.

    Or if you screwed up something,look at the key code while resetting(it's called Splash screen,that shows up before POST),and press it.
    Press Pause/Break key if it goes too fast.
    Common keys are F1,F6,F8,F12,Delete,Ctrl+Shift+ESC,Escape(ESC).
    Go to main menu,select Load Optimized Default,press Y and Enter,and wait for the computer to reset.

    If you messed up something and you can't get past the Splash screen(POST failed),go to the back of the computer,undo TWO screws at your RIGHT side with vent(if you are seeing ports) and undo the cover,find a jumper named "CMOS CLEAR" or "CMOS_1",and briefly change the position from Default to Reset.
    Or remove coin cell battery from the motherboard and replace it with + side labeled facing you,or to the top.
    TURN OFF THE COMPUTER BEFORE DOING THIS!
    Because this deals with ADMINISTRATIVE LEVEL OF ACCESS,you can literally trash the computer,no matter how good or bad it is.
    I've seen many students ruining computers while setting things with BIOS Menu. (And I used to pick those thrown-away computers and reuse it)

    More on this later.
