Cybersecurity Attack Types, Impacts And Countermeasures TYPES OF ATTACKS

COUNTERMEASURES

Confidentiality Attacks: Unauthorized access to sensitive data via spyware, malware, brute-forcing, or cloning.

Encryption: Use TLS and database encryption to secure sensitive data.

Integrity Attacks: Malicious data modification, including false data injection, random delays, and replay attacks. Availability Attacks: Disruption of system functions, such as denial-of-service DoS) attacks.

Resilient Software Design: Implement secure algorithms, robust state estimators, and secure coding practices. Hardware Security Modules HSMs Ensure software authenticity, integrity, and secure communication. User Authentication: Require multifactor authentication for sensitive data access. Cross-Verification: Compare onboard and cloud BMS computations to detect anomalies.

IMPACTS OF ATTACKS

Physical Protection: Secure housing, remove unnecessary ports, and hardwire components.

Functional Impacts: Malfunctions, such as "denial-of-charging" attacks.

Data Transparency: Involve human oversight in data and algorithmic decisions.

Financial Loss: Premature maintenance or battery replacement due to degradation.

Wireless BMS Security: Secure keys, Authenticate and Encrypt wireless communication and secure debug ports.

Safety Risks: Overcharging, over-discharging, or compromised cooling systems causing thermal runaway or fires.

Anomaly Detection: Combine battery modeling, state estimation, and statistical methods to detect false data injection attacks.

Side Impacts: Corrupted data affecting future battery models and algorithms.

Defense-in-Depth: Layer physical, network, and device security with a zero-trust approach.

Grid Instability: V2G attacks disrupting frequency and voltage in the power grid.
