    layer of the IT learning continuum that seeks to inform and focus an employee's attention on issues related to security within the organization - explains the what but not the how of security
  3. training
    layer of the IT learning continuum designed to teach people the skills to perform their IS-related tasks more securely - teaches what people should and how to do it

  5. least priviledge - give each person the minimum access necessary to do his job

  8. Computer Security Incident Response Team (CSIRT) aka Computer Incident Response Team (CIRT) or a Computer Incident Response Center (CIRC)
    a capability set up for the purpose of assisting in responding to computer security-related incidents that involve sites within a defined constituency
  9. constituency

  14. system integrity verification tools
    scan critical system files, directories, and services to ensure they have not been changed without proper authorization
  15. log analysis tools
    analyze the information collected in audit logs using some form of pattern recognition to identify potential security incidents
  16. network and host indrusion detection systems (IDS)
    monitor and analyze network and host activity and usually compare this information with a collection of attack signatures to identify potential security incidents
  17. intrusion prevention systems
    augment an intrusion detection system with the ability to automatially block detected attacks
  18. system integrity verivfication tools
    log analysis tools
    network and host intrusion detection systems (IDS)
    intrusion prevention systems
