  1. 1. 1Cyber Threats
  2. 2.  At the end of this lesson, the student should be able to:  Define cyberterrorism and cyberwarfare;  Identify five types of cyber attacks and understand the damage that cyber attacks can inflict;  Discuss several recent examples of cyber attacks;  Identify and explain the roles of two organizations involved in defending US cyberspace. Counterintelligence 2
  3. 3. “The use of computer networks to shut down critical infrastructure (such as energy, transportation, government operations) or to coerce or intimidate a government or civilian population.” (Source: Center for Strategic and International Studies) Cyber Threats 3
  4. 4.  Information war “The use of computers and other devices to attack an enemy’s information systems as opposed to an enemy’s armies or factories.” (Source: American Heritage New Dictionary) Cyber Threats 4
  5. 5.  Trojan Horse: A computer program that conceals harmful code. A Trojan horse usually masquerades as a useful program that a user would wish to execute. Virus: A program that infects computer files, usually executable programs, by inserting a copy of itself into the file. These copies are usually executed when the infected file is loaded into memory, allowing the virus to affect other files. Unlike a computer worm, a virus requires human involvement (usually unwitting) to propagate. Cyber Threats 5
  6. 6.  Phishing: Using emails and websites designed to look like those of legitimate businesses/government agencies to deceive internet users into disclosing personal data, e.g. bank and financial account information and passwords. DoS (Denial of Service): A method of attack from a single source that denise system access to legitimate users by overwhelming the target computer with messages and blocking legitimate traffic. It can prevent a system from being able to exchange data with other systems of use the internet. Cyber Threats 6
  7. 7.  Distributed Denial of Service (DDoS): A variant of the DoS attack that uses a coordinated attack from a distributed system of computers rather than from a single source. It often makes use of worms to spread to multiple computers that can then attack the target. Counterintelligence 7
  8. 8. Titan Rain (2003+) Series of coordinated attacks on US computers Thought to be Chinese in origin NASA, Lockheed Martin, and other vital organizations penetrated Counterintelligence 8
