Data Analysis vs. Data Analytics

Analysis is focused on understanding the past; what happened and why it happened. Analytics focuses on why it happened and what will happen in the future.

  • Some treat data analysis as a process, part of data analytics, while data analytics as a discipline.
  • Data analysis answers, “What happened?” while data analytics answers, “Why, and What will happen next?
  • Data analysis relies on descriptive statistics, while data analytics relies on inferential statistics.

Attribute-Based Access Control (ABAC)

An access control method where subject requests to perform operations on objects are granted or denied based on:

  1. assigned attributes of the subject,
  2. assigned attributes of the object,
  3. environment conditions, and
  4. a set of policies that are specified in terms of those attributes and conditions.

Context-Based Access Control (CBAC)

The term CBAC is coined by Cisco, not a typical access control mechanisms you encountered in most of the CISSP study guides or NIST guidelines.

The Context-Based Access Control (CBAC) feature of the Cisco IOS® Firewall Feature Set actively inspects the activity behind a firewall.

Which of the following indicators provided by threat feeds provides the most value?
A. Host Artifacts
B. Domain Names
C. Hash Values
D. Tools

Criticality Analysis and BIA

  • Criticality is the degree of impact of missing something important, e.g., critical process, activity, resource, or system. Criticality analysis is the process of determining the criticality.
  • Business impact analysis (BIA) that comprising criticality analysis identifies
    1. critical activities that support the delivery of products and services,
    2. supporting activities and dependencies, and
    3. other assets and resources.
  • The more critical an activity is, the shorter its tolerable downtime is. BIA identifies activities and determines their MTDs, RTOs, and RPOs to prioritize them as critical activities. In summary, criticality analysis is part of BIA.
