• SOME FACTS
• I am not all knowing
• I am hoping you will learn something new here
  today

5

• SOME FACTS
• The Slammer worm was relentless. In the first
  minute of existence, it doubled the number of
  machines that it infected every 8.5 seconds. In
  just three minutes it was scanning 55 million
  targets per second! Within 10-minutes, 90 percent
  of all unprotected computers in the world were
  infected. Luckily that is all that it did was
  spread. What a nightmare it would have been if it
  carried a payload that actually damaged
  computers.

Take steps to ensure yoursystem is secure!

• Securing Your Operating System
• First thing to protecting yourself is to become
  familiar with what types of attacks there are on
  the Internet.
• Always Think First, and Ask QuestionsWhen in
  doubt, DELETE or CLOSE the screen (right click on
  the bottom of the screen and choose close)!
• Be careful who you trust and what information you
• provide online.
• Know what data you have, where it is and that
  its
• secured.
• Dont let your private life become part of the
  Internet.

13

• Securing Your Operating System
• Good Passwords
• At Least 8 Characters Long
• No Dictionary Words - (Forwards OR Backwards)

• Do Not Tell ANYONE! Not Me, Not Anyone!
• If it is absolutely necessary for maintenance
  and/or a trusted repair person you can give them
  a temporary password. After they are done,
  change it immediately.

15

• Securing Your Operating System
• Good Passwords
• Your Password should be a unique combination of
  letters, numbers and a special character
• (i.e. Y_at_nkeyD00dle )

16

• Securing Your Operating System
• Good Passwords
• Example of BAD passwords

17

• Securing Your Operating System
• It is very important to assign passwords to your
  user accounts on your computer this will keep
  your DATA safe and secure
• Setting The Windows Administrators Password
• Start -gt Run -gt control userpasswords2

18
Securing Your Operating System
Highlight Administrator Choose Reset Password
Clear the User Name field and Rename it
19

• Securing Your Operating System
• Setting The Mac OS X Root Password
• Root Account DISABLED by Default
• Net Info Manager
• Authenticate
• Enable Root User
• Create Root Password

• What Is A Virus?
• "A parasitic program written intentionally to
  enter a computer without the user's permission or
  knowledge. The word parasitic is used because a
  virus attaches to files or boot sectors and
  replicates itself, thus continuing to spread.
  Though some viruses do little but replicate,
  others can cause serious damage or affect program
  and system performance. A virus should never be
  assumed harmless and left on a system." --
  Symantec

Securing Your Operating System

• Types of Computer Viruses
• Basic Virus - a piece of software code that is
  developed to attack computers and network
  entities via email or Internet connections. It
  quickly replicates itself and gradually attaches
  to files, programs or the hard drive.
• Trojan Horse - This is a type of benign program,
  a malicious code that doesn't replicate when
  entering a system but can be effectively used to
  open 'back doors.' Trojan Horses allow hackers to
  assume control over a particular system or to
  steal vital data. As an example, QAZ helped
  hackers view the secret source code at
  Microsoft-owned network.
•  Worm - this type of virus has the capability to
  spread itself automatically over the network from
  one computer to the next. During a worm attack,
  users' computers get infected without even having
  to click open email attachment or any program,
  etc. As an example, in the early August of 2003,
  a worm by the name of Blaster infected more than
  1 million computers worldwide. In similar case,
  Welchia, an antidote to Blaster, clogged huge
  amounts of network computers and caused computers
  crashes.
•  Blended or a Combination Attack - covers
  innovative strategies to infect and spread
  various viruses within computer networks. It
  involves basic virus, worm, and Trojan Horse
  techniques where attackers can use peer-to-peer
  networks and instant messaging systems to channel
  such viruses. In the mid-August of 2003, SoBig, a
  virus, infected nearly every other email
  traveling on the Internet at its peak.

• How They Infect
• Open Ports (Worms, Trojans)
• A port is a method on how your computer connects
  to the Internet (it is like a room full of doors
  and you choose which one to go through)
• Removable Media (Floppy Disk, Memory Card)
• Downloads (WWW, FTP, P2P)
• Email (Attachments, Scripts)

• Computer Maintenance Checklist
• At system setup
• Install a surge suppressor/emergency shutdown
  power strip
• Register your software products
• Schedule automated updates
• Read the maintenance section of your manual
• Set up your email to auto-archive older messages
  (if you are using that type of email program
  (i.e. Microsoft Outlook)
• Install anti virus software
• Install anti-advertising/malware software
• Put your software drivers (does anyone know what
  a software driver is??) in a pocket sleeve 3 ring
  binder

Keeping your system up to date
28

• Weekly
• Run a disk scan to check for hard drive issues
  (demo)
• Run a defragmentation program in Windows Vista
  and 7 this is done automatically)
• Run a clean up to delete unneeded files (demo)
• Back up your files to a remote location (I
  suggest Mozy Pro)
• Empty your recycle bin
• Delete your Internet files (demo)
• Clear your browsing history (demo)
• Delete your cookies (demo)
• Update your virus definitions
• Run a full virus scan

Keeping your system up to date
29

• Monthly
• Check for updates
• Delete/uninstall unneeded or unused programs
• Quarterly
• Clean your keyboard and mouse (alcohol pads and
  canned air) I have a story about canned
  air
• Clean your monitor
• Clean your peripherals
• Rebuild your desktop (this is not an easy task,
  please make sure you get a professional to do
  this or ask a friend to help or myself) -- MOST
  IMPORTANT, BACK UP YOUR DATA
• Change all your passwords

Keeping your system up to date
30

• Yearly
• Renew your software update and anti virus
  subscriptions

Keeping your system up to date
31

• Installing Applications
• Only install applications that you need
• If you install to many applications, your hard
  drive will slowly fill up with files and will
  cause it to be slow over time (also, even if you
  think that uninstalling an application will speed
  up your computer, that is not always a truth
  some applications leave behind files and could
  cause issues later on)

Keeping your system up to date
32

• Which Operating System is best for me??
• It is all about preference (what works best for
  me?)

• Windows 7
• MAC OS X
• Linux (Ubuntu, Fedora, Red Hat)
• No matter which Operating System you choose,
  always remember, it can get a virus, you need to
  keep it up to date and you need to back up your
  data

35

• Wired vs. Wireless
• Some Pros and Cons
• Wired can be more fast (some wired connections
  have faster speeds than wireless)
• Wireless allows you to be anywhere in your home
  and still connected to the Internet
• Wired connections can be more secure (in some
  cases than wireless)
• Wireless connections can be less secure if you
  dont have the proper encryption enabled on your
  wireless access point

Connecting to the Internet
36

• Which Internet Browser is best for me
• It is all about preference (what works best for
  me?)
• Windows Internet Explorer
• Integrates really well with Windows OS
• Probably the most targeted (hacked, virus)
  browser in the world
• Mozillas Firefox
• It is very extendable (customizable)
• Apples Safari
• Apples answer to browsing
• Not very customizable
• Googles Chrome
• Googles answer to browsing
• Not very customizable
• Opera
• Operas answer to browsing
• Not very customizable

38

• Safe/Smart Surfing
• First rule of smart surfing? Remain as anonymous
  as possible. That means keeping all private
  information private. Here are some examples of
  private information that you should never give
  out on the Internet
• full name
• home address
• phone number
• Social Security number
• passwords
• names of family members
• credit card numbers

Connecting to the Internet
39

• Keeping your information safe on the Internet
• The best way is not to put anything out there
• No personal information should be shared with
  anyone you dont know
• If you use Facebook, MySpace, Linkedin, etc
  understand that everything you say, express and
  post (i.e. photos) are available for the world to
  see Also, remember that once something is
  posted on the Internet it could potentially be
  there forever. The all mighty Google may have
  already cataloged it.

• If you have children, it might be a good idea to
  use some sort of preventative measures to keep
  them safe
• First thing is talk to them about Internet and
  let me know the about the dangers keeping their
  personal information safe
• If you are worried that they might go to unsafe
  places on the Internet you can install programs
  on to your computer to help them stay safe (i.e.
  McGruff SafeGuard, CYBERSitter and NetNanny).
  Windows Vista and Windows 7 have a similar
  programs built-in

Connecting to the Internet
41

• Downloading Files, Music and Applications from
  the Internet
• My best advise to you about any of this is dont
  do any of it
• If you have to download something, I suggest you
  have updated AntiVirus software and Anti-Malware
  software
• For Music, I suggest using iTunes or another
  reputable company to download your music. Stay
  away from companies like LimeWire and other
  free music download sites. They typically have
  a lot of virus associated with them

Connecting to the Internet
42

• Email
• The best way to keep from getting these, is to
  only open emails from people you trust
• SPAM (video)
• Phishing
• These people are trying to get you to give them
  information about personal online accounts (i.e.
  ebay, paypal, etc)
• Attachments
• Only time you should open email from anyone is if
  you trust the person and you are expecting
  something from them (next to Phishing, this is
  the 1 way people get virus)

Connecting to the Internet
43

• Email
• Dont get fooled by the emails with attachments
  like, If you forward this email you will receive
  100 in 100 days
• Remember if you are going to forward an email to
  friends and family, it is important to not
  include the previous email addresses from the
  attached email.
• Also, if you have a group of emails that you plan
  to send to, it is best to blind carbon copy (BCC)
  them

• Malware
• Malware, short for malicious software, is
  software designed to infiltrate a computer system
  without the owner's informed consent. The
  expression is a general term used by computer
  professionals to mean a variety of forms of
  hostile, intrusive, or annoying software or
  program code.1 The term "computer virus" is
  sometimes used as a catch-all phrase to include
  all types of malware, including true viruses. -
  wikipedia
• Intrusive-ware (not an official term, that is
  what I call it)
• It is almost the same as Malware however, it has
  all of the characteristics of a legitimate piece
  of software. Example, a program that looks and
  feels like your AntiVirus program however, it
  keeps telling you that you have virus and the
  only way to make these pop-ups go away, is to buy
  their software. Now they may have your money,
  your computer and possibly your identity.

• Misconceptions about your computer
• Upgrading (to the next version of Windows, Linux
  or MAC OS X) will not always fix the issue
• Running a virus scan and/or a anti-malware will
  not always fix your issue

47

• Keeping yourself from having to call a technician
  or repair person
• Follow these 4 simple rules
• Be mindful of where you go on to the Internet (if
  you think it is doesnt look or feel right, then
  it isnt close your browser and/or just turn off
  your computer)
• Update your computer with your AntiVirus
  definitions and Window Updates
• Back up your data to an external hard or an
  external company (i.e. Mozy Pro)
• Follow the Weekly, Monthly, Quarterly, Yearly
  plan (as mentioned above)
