AP Cybersecurity alignment
- 2.1.D.3Risk assessment considers two factors: • The likelihood of an attack against a specific vulnerability • The severity of the projected damage from an attack against a specific vulnerabilityLearning objective: Describe the risk assessment process.
- 2.1.E.4Risk mitigation implements security controls to reduce the likelihood or impact of a risk.Learning objective: Identify strategies for managing risk.
- 2.2.B.1Threats include human adversaries seeking to cause harm or disruption as well as natural disasters. Natural disasters can cause physical damage or destruction to computers and data as well as disruption of digital services…Learning objective: Explain how threats can exploit common physical vulnerabilities to cause loss, damage, disruption, or destruction to assets.
AP Networking alignment
- 4.1.A.5When availability is compromised, systems have unexpected periods of time when they are out of service. A breach of availability can be identified by: • an inability to access systems, networks, or resources • slow or dropped…Learning objective: Identify evidence of compromised confidentiality, integrity, or availability.
- 4.4.B.4When multiple next hops are available, the route with the lowest metric is chosen. Metrics can change over time based on network conditions such as congestion, device failure, or changes in link speed, which may cause data to…Learning objective: Explain how routing protocols and metrics influence the path of data.
- 4.6.B.1Redundancy improves network reliability by ensuring backup solutions are available if a primary system fails. Common redundancy strategies include: • implementing backup power through generators or UPS • connecting secondary…Learning objective: Identify ways to improve the reliability and availability of networked systems.
