Electrical grid network has
“Backdoors” to let bad guys in
whenever they choose
Cyber threats are now
considered
"Cybersecurity is
the soft underbelly
of this country."
Weapons of Mass
Destruction!

Cyber Security Act of 2009
“…the president may order a Cybersecurity emergency and order the
limitation or shutdown of Internet traffic"
• Give Federal Government access to detailed network data
• Create a new Cybersecurity “Czar”
• Is supposed to coordinate military, NSA, Commerce & DHS efforts
A Hacker’s View of the State of Idaho:
• Target
• Government networks are a valid target
• Corporations are valid targets
• Individuals are a target
• Identity and privacy information = big target
Overarching Security Issues:
Electrical grid Cyber attacks
• Won’t stop the wind blowing
• Can’t stop the water flowing
• Can stop the power to
• You
• Your house
• Your workplace
• Stoplights...
Growing security trends:
•
Huge increase in spam (Phishing, e-cards, etc.)
•
New Threats: Vishing, Pod-Slurping, Thumb-sucking, more
•
Development of wireless hacking & mobile device viruses
•
Increase in video sharing exploits (PC or mobile)
•
Significant Increase in “Drive-by” malicious-ware websites
•
Increase in “Bots” & rootkits; hard to find or stop

Average people… make
mistakes
• Visit a site with poor security
• Obvious (e.g., pornography)
• Not obvious (e.g., MySpace,
Facebook)
• Even trusted sites – thousands
every day
• Download from the Internet
Average people… make mistakes
• Install potentially dangerous
software
• Freeware / Shareware
• Unchecked software
• Games
• Toolbars (e.g., Google Toolbar)
• Rights & access must be
minimized
Cisco Study: Laptop users bring threats into networks
• 56% believe Internet
is now “safer”
• Less “destructive”
viruses
• More security
products
• Limited awareness
“Script Kiddies” or Hacker intraining
• Use tools developed by real
Hackers
• Find excitement in breaking-in
• “Bragging Rights”
• Often purposely leave evidence
• Build a rep
• Rarely want long term
exploitation
Anyone could be an insider
• Studies show insiders bring huge
losses
• Victims at HUGE risk
• 12 times more likely hit by fraud

If there’s a profit or edge to

• Foreign governments
• Active attacks
• Network “backdoors”
• Use daily or hold for hostilities
If there’s a profit or edge to
gain
• Corporations
• Information is power
• Corporate intelligence activities
growing
• Is it ethical in the market place?
Developing new viruses all the time
• Created mostly by criminals
• A recent popular one is:
• JSRedir-R Trojan or “Gumblar”
• Infecting a new webpage every
4.5 seconds – legitimate sites
• Loads without knowledge
Refining Social Engineering
• “Twitterpornnames”
• Facebook and many other examples
Global cybercrime is the biggest
profit maker for criminals
• Surpassed drug trafficking
• Is not as dangerous as dealing
drugs or robbing banks, etc.
• True hackers selling services to
non-technical criminals
• Expertise is growing rapidly
• Money gets bigger every
month
• Software has vulnerabilities
• We need software
• To do our jobs
• To entertain ourselves
• To make life easier
• Over 90% of attacks are on
known vulnerabilities
• Patches are already out
• “Zero Day” exploits always a
possibility
• Password security is critical!
• Ensures only you can access your computer
• And the network behind it
• Use strong passwords always
• You will be attacked at the point of the weakest link
• NEVER give your network password to anyone else!
• Don’t write it down!
• Use as long a password as you can and ensure it has

• Spyware infects >80% desktops
• P2P software can come with Spyware
• Now too prevalent and insidious
• Your Anti-virus will not find it all
• Precursor to Trojans and/or Botnet

Rogue anti-virus/spyware programs
• Often generate more "alerts" than reputable software
• May bombard you with pop-ups, even when not online
• Use high-pressure sales to convince you to buy RIGHT NOW!
• Other signs of infection include:
• new desktop icons
• new wallpaper
• default homepage redirected to another site
Surfing the web is becoming a more
treacherous adventure

Step 1: Understand that computer user involvement is key to
successful network / cyber security
Step 1a:
Don’t
Be
Scared
Step 2 – Manage Risk
• Rapidly changing landscape for IT solutions
• Constantly changing IT security environment
• Security tools are growing – capability, complexity, cost
• IT budgets won’t increase as quickly as demand
Analyze the security environment – focus on the risk
• What information / resources are you protecting
• What are the threats to your information / assets
• What is the risk to the organization if information /
asset is
• Lost
• Stolen
• Changed
• Develop a security plan to manage your risk
• Develop a security budget based on the security plan
• Assign the right people manage and run with the plan
Step 3: Take security seriously at work

Use strong passwords
Lock your workstations
Use care with e-mails
Do not download from the Internet
Do not install unchecked programs – rely on IT
Be aware of your Anti-Virus – is it running?
Laptop Firewalls should be on if away from the office
Make backups of important files and folders
Use a file encryption process
Ensure Security is part of all Business and IT Plans
Step 4: Take security seriously at home
• Install / Use Anti-Virus & Spyware programs
• Install / Use a Firewall program
• Keep system patched – all your programs
• Use care when reading e-mail
• Make backups of important files and folders
• Use strong passwords (different ones for different sites)
• Use care when downloading and installing
• Consider using a file encryption program
Step 5: Assess success of security procedures:
• Are risks mitigated?.. reduced?
• Modify plan when necessary
• Overcome disappointment; security can’t stop all attacks
• Experts are no longer saying “if” but “when”
Good Security can make you happy
