Know about legacy system security risk. Legacy systems are often a threat because they may not be receiving security updates from their vendors. End-of-life (EOL) is the point at which a manufacturer no longer produces a product. End-of-service-life (EOSL) or end-of-support (EOS) are those that are no longer receiving updates and support from the vendor.
Know about risk frameworks. A risk framework is a guideline or recipe for how risk is to be assessed, resolved, and monitored. The primary example of a risk framework referenced by the CISSP exam is the Risk Management Framework (RMF) defined by NIST in SP 800-37 Rev. 2. Others include ISO/IEC 31000, ISO/IEC 31004, COSO, Risk IT, OCTAVE, FAIR, and TARA.
Understand social engineering. Social engineering is a form of attack that exploits human nature and human behavior. The common social engineering principles are authority, intimidation, consensus, scarcity, familiarity, trust, and urgency. Such attacks may be used to elicit information or gain access through the use of pretexting and/or prepending. Social engineering attacks include phishing, spear phishing, business email compromise (BEC), whaling, smishing, vishing, spam, shoulder surfing, invoice scams, hoaxes, impersonation, masquerading, tailgating, piggybacking, dumpster diving, identity fraud, typo squatting, and influence campaigns.
Know how to implement security awareness training and education. Before actual training can take place, awareness of security as a recognized entity must be created for users. Once this is accomplished, training, or teaching employees to perform their work tasks and to comply with the security policy, can begin. All new employees require some level of training so that they will be able to comply with all standards, guidelines, and procedures mandated by the security policy. Education is a more detailed endeavor in which students/users learn much more than they actually need to know to perform their work tasks. Education is most often associated with users pursuing certification or seeking job promotion.
Know about security champions. Often a security champion is a member of a group who decides (or is assigned) to take charge of leading the adoption and integration of security concepts into the group's work activities. Security champions are often non-security employees who take up the mantle to encourage others to support and adopt more security practices and behaviors.
Understand gamification. Gamification is a means to encourage compliance and engagement by integrating common elements of game play into other activities, such as security compliance and behavior change.
Know about the need for periodic content reviews and effectiveness evaluations. It is important to perform periodic content reviews of all training materials. This is to ensure that the training materials and presentation stays in line with business goals, organizational mission, and security objectives. Some means of verification should be used to measure whether the training is beneficial or a waste of time and resources.
