Automotive Design Process

Creating a vehicle involves an attractive design process starting with sketches, dividing the vehicle into front and rear sections, and utilizing computer-aided design (CAD).

External Design Factors

• Aerodynamics: Drag coefficient and air friction.
• Ergonomics: Driver and passenger comfort.
• Specifications: Ground clearance, fuel tank capacity, wheel size, bumper dimensions, and engine type.

Measurement and Technical Conditions

Key considerations include visibility, mechanical features, ease of manufacturing, and safety standards.

Body Design and Software

Designers utilize Computer-Aided Design (CAD) and Computer-Aided Engineering (CAE). Common software includes Catia and other engineering programs.

Social Engineering

Social engineering consists of manipulating or deceiving people in order to obtain information or make them perform an action, usually without them realizing the attack. Instead of directly attacking technology, the attacker exploits human behavior and trust. It is the basis of many cyberattacks, especially phishing.

Phishing

Phishing is a social engineering attack in which an attacker impersonates a legitimate or trusted entity in order to deceive the victim into revealing sensitive information or performing an action. It may use fraudulent emails, websites, domains or servers and can be used to obtain credentials, banking or personal information, money, or to make the victim open a malicious link or file.
