  This short paper is presented in observance and promotion of November, the
National Month of Critical Infrastructure Security and Resilience (CISR),
established by the United States Department of Homeland Security in 2013. The
CISR term focuses on essential assets (critical infrastructures) and two
ultimate goals of making them secure and resilient. These assets and goals were
put together in 2013 in the now well-known Presidential Policy Directive on
CISR (PPD-21). This paper presents easy-to-ready material laying down the
building blocks of CISR - what it means to you as a regular citizen,
professional, or government worker. This paper presents concepts behind
security and resilience pertinent to various types of activities - from every
day to field-specific activities. This paper also presents basic elements to
the field: 1. high-level introduction to the organizational units dealing with
CISR in the United States; 2. explanation of basic terms and a list of further
reading material; and 3. several discussion topics on the vision and future of
CISR in critical infrastructure cyber-physical systems.
