AP Cybersecurity alignment
- 4.3.C.2Ensuring that a computer’s operating system and software applications are updated to the most recent version prevents adversaries from taking advantage of a known vulnerability.Learning objective: Explain why keeping a device’s operating system and software updated makes it more secure.
- 5.2.C.7The principle of least privilege is the idea that entities should be given exactly as much access as they need to perform their function and no more.Learning objective: Determine an appropriate access control model to protect applications and data.
- 5.2.D.1Authorization is when an entity is granted permission to have a certain type of access to a resource. Access controls are put in place to control which users have what types of access to which data.Learning objective: Configure access control settings on a Linux-based system.
AP Networking alignment
- 4.5.A.3Widespread data compromise, service outages, or loss of administrative control can occur when an adversary or malicious software moves laterally across a network. These impacts are more likely in segmented or large networks…Learning objective: Identify the impacts of common threats and vulnerabilities in a managed network.
- 4.5.B.4Security controls to limit the impact of unauthorized access include: • enforcing strong password policies and account lockout settings • applying the principle of least privilege • implementing segmentation to restrict access…Learning objective: Determine appropriate security controls to limit the impacts of common threats and vulnerabilities in a managed network.
- 4.6.B.4Applying and documenting software updates and patches reduces the risk of failure and reduces recovery time if an outage occurs.Learning objective: Identify ways to improve the reliability and availability of networked systems.
