Study Notes

Hacking

Involves unauthorized access to computers or networks, typically through the internet.
Motivations include data theft and system sabotage.
Cyberterrorism includes internet-based attacks by terrorists.
Wireless networks are common targets due to their accessibility and ease of hacking compared to wired networks.

War Driving and Wi-Fi Piggybacking

War driving involves searching for unsecured Wi-Fi networks by driving around a location.
Wi-Fi piggybacking refers to unauthorized access of an unsecured Wi-Fi network from a nearby location.
These activities can foster illegal behavior.

Access Control Systems

Designed to manage access to facilities, networks, and databases.
Identification systems verify users attempting to access services.
Identity Management (IDM) helps administer user access to corporate systems.

Possessed Knowledge Access Systems

Use secret information known only to the individual for access verification.
Passwords, comprising a combination of characters, are essential for securing access to devices and networks.
Pins and passcodes serve as numerical passwords, utilized in conjunction with usernames.

Possessed Object Access Systems

Rely on physical objects (e.g., smart cards, RFID badges) for identification.
Security tokens can be lost, leading to potential access issues.

Encryption

Converts data into an unreadable form (cipher) to protect it from unauthorized users.
Utilizes both private key (symmetric) and public key (asymmetric) encryption methods for data security.
Enhances protection for data transmitted over networks, including secure web pages using Transport Layer Security (TLS).

Network Security Measures

Employ WPA3 for robust Wi-Fi security.
Regular software updates and security patches are critical.
Implement the principle of least privilege, granting only necessary access permissions.

User Training and Awareness

Educating users about security risks and best practices is vital to protect against unauthorized access.

Role-Based Access Control (RBAC)

Limits system access based on user roles within an organization.
Regular audits help in identifying unusual activities and safeguarding the system.

Biometric Access Systems

Utilize unique physical traits (e.g., fingerprints, facial recognition) for user identification.
Effective for access control to secure locations and systems, including ATMs.

Controlling Access to Wireless Networks

Secure network routers are essential for protecting wireless communications.
Standards like WEP, WPA, and WPA2 enhance network security.

Firewalls

Serve as protective barriers against unauthorized access to networks or computers.
Monitor both incoming and outgoing traffic to only permit authorized data.
Personal firewalls can be standalone applications or integrated into operating systems, such as Windows Firewall.

Enhanced Access Protection

Strong passwords should incorporate a mix of uppercase and lowercase letters, numbers, and symbols.
Ensure secure password reset procedures are in place.
Implement Two-Factor Authentication (2FA), using two different forms of user verification.
