Study Notes
Wireless and Mobile Security Overview
- Wireless networks present unique security challenges compared to wired networks due to signal broadcasting and external accessibility.
- Many commercial wireless networks are not regulated by customers, making traffic vulnerable to potential threats.
RFID Technology
- RFID systems use active, semi-active, or passive tags to transmit information.
- Tags operate on three frequency ranges:
- Low-frequency RFID: Used for short-range applications, such as entry access, subject to inconsistent standards globally.
- High-frequency RFID: Supports near-field communication and offers a longer readable range, suitable for various applications, including inventory management.
- Ultra-high-frequency RFID: Fastest reading with the longest range, effective in scenarios requiring distance from readers.
- RFID tags are susceptible to attacks, including destruction, cloning, and traffic interception.
Bluetooth Security Threats
- Bluetooth attacks include bluejacking (sending unsolicited messages) and bluesnarfing (unauthorized data access).
- Pairing codes for Bluetooth devices are often weak, leading to vulnerabilities.
- Bluetooth impersonation attacks exploit weaknesses in mutual authentication and role-switching within Bluetooth specs, prompting concerns for device security.
Wireless Attack Techniques
- Disassociation attacks force devices to disconnect, offering attackers a chance to initiate reconnection processes with malicious setups.
- The deauthentication frame can be spoofed to disconnect a device, and while WPA2 networks are vulnerable to this, WPA3 enhances security with protected management frames.
Network Design Considerations
- Effective Wi-Fi network design demands optimal placement and configuration of wireless access points (WAPs) to ensure performance and security.
- Conducting site surveys is crucial to gauge existing network configurations and identify suitable WAP locations, particularly in established structures.
- Wireless signal must be contained within intended spaces to prevent unauthorized external access, necessitating careful planning during the deployment phase.
