  • Addressing CIP: A Thailand Case Study by Chaiyakorn Apiwathanokul CISSP, GCFA, IRCA:ISMS Chief Security Officer PTT ICT Solutions Co., Ltd. A Company of PTT Group Note: CIP = Critical Infrastructure Protection
  • Addressing CIP: A Thailand Case Study by Chaiyakorn Apiwathanokul, CISSP, GCFA, IRCA:ISMS Synopsis: In many countries where Critical Infrastructure Protection is not yet a regulatory requirement or is not taken into account seriously by their government; the perception, understanding, collaboration and qualified workforce is big challenge. Many misperceptions about securing those systems make it hard to convince management and stakeholders to support activities and investments. However, the legislation is not the only way to go; there are still many other factors that can be pulled into the scene ex. BCM, Risk Management and etc. to help attract the managements. As a security professional, how can we make things better? How can we utilize other mechanisms available to help addressing this challenge? In Thailand even though we do not explicitly issues a law specifically for CIP, we have done something to addressed CIP in some extents. We help raise awareness and understanding through trainings and seminars to demonstrate the vulnerability and exploitability of such systems. We introduce ISO27001 as a basic security management framework. Of course, there are many other things that need to be done to address this challenge.

  • Transportation System From a movie
  • Italian Traffic Lights In the real world Event: Feb, 2009 Italian authorities investigating unauthorized changes to traffic enforcement system Impact: Rise of over 1,400 Lessons learned: traffic tickets costing > 250K  Do not underestimate the Euros in two month period insider threat Specifics: Engineer accused of  Ensure separation of conspiring with local authorities duties and auditing to rig traffic lights to have shorter yellow light causing spike in camera enforced traffic tickets
  • Transportation – Road Signs In the real world Event: Jan 2009, Texas road signs compromised Impact: Motorists distracted and provided false information Specifics: Some commercial road signs can be easily altered because their instrument panels are frequently Lessons learned: left unlocked and their default  Use robust physical access passwords are not changed. controls "Programming is as simple as  Change all default passwords scrolling down the menu selection," a  Work with manufacturers to blog reports. "Type whatever you want identify and protect password to display … In all likelihood, the crew reset procedures will not have changed [the password]." 8
  • Building Automation System (BAS) From a movie
  • Security Guard Busted For Hacking Hospital's HVAC, Patient Information Computers, July 2009 In the real world • "A former security guard for a Dallas hospital has been arrested by federal authorities for allegedly breaking into the facility's HVAC and confidential patient information computer systems. In a bizarre twist, he posted videos of his hacks on YouTube, and was trying to recruit other hackers to help him wage a massive DDoS attack on July 4 -- one day after his planned last day on the job. • Jesse William McGraw, 25, also known as "GhostExodus," "PhantomExodizzmo," as well as by a couple of false names, was charged with downloading malicious code onto a computer at the Carrell Clinic in order to cause damage and as a result, "threatened public health and safety," according to an affidavit filed by the FBI . McGraw worked as a night security guard for United Protection Services, which was on contract with hospital, which specializes in orthopedics and sports medicine."
  • In the real world CIA Admits Cyber attacks Blacked Out Cities • The disclosure was made at a New Orleans security conference Friday attended by international government officials, engineers, and security managers. • The CIA on Friday admitted that cyberattacks have caused at least one power outage affecting multiple cities outside the United States.

  • Commonly Claim: The system is isolated In the real world Virus Found On Computer In Space Station NASA confirmed on Wednesday that a computer virus was identified on a laptop computer aboard the International Space Station, which carries about 50 computers. The virus was stopped with virus protection software and posed no threat to ISS systems or operations, said NASA spokesperson Kelly Humphries. … The SpaceRef report suggested that a flash card or USB drive brought on board by an astronaut may have been the source of the laptop infection.
