Security Standards Conclusion

This module discussed the concept of security and demonstrated several security threats.
You also learned about the categories of resources that need protection, the attributes of an effective security system, and the types of people who make security systems necessary.

Now that you have completed this module, you should be able to:
  1. Describe security and security statistics
  2. Define risk analysis
  3. List the attributes of an effective security system
  4. Describe security standards in current use
  5. Plan a security policy for your business
  6. Increase security effectiveness by establishing organizational training

  14. Password cracking: An attempt by a hacker to access a network using possible passwords. A dictionary file is often used to crack passwords.
  15. Password sniffing: Finding a way to intercept the transmission of a password during the authentication process. A sniffer is a program used to intercept passwords.
  16. Security system: All components used by a company to provide a security strategy, including hardware, software, employee training, and a security policy.
  17. Social engineering: The use of tricks and disinformation to gain access to passwords and other sensitive information.
  18. Sniffer: A program used to intercept passwords.
  19. Spoofing: A form of identity theft in which a hacker attempts to defeat authentication. Specific examples include IP spoofing, ARP spoofing, router spoofing, and DNS spoofing.
  20. System snooping: The action of a hacker who enters a computer network and begins mapping the contents of the system.
  21. Trojan (trojan horse): A file or program that purports to operate in a legitimate way, but which also has an alternative, secret operation, such as emailing sensitive company information to a hacker. A trojan horse is a specific program that destroys information on a hard drive.
