Study Notes

Security Risks in Mobile Systems

  • Messaging systems (SMS, MMS) are a source of security risks
  • Connection channels (Wi-Fi networks, GSM) are vulnerable to attacks
  • Software/OS vulnerabilities and malicious software pose security threats
  • User recognition/authentication, encryption methods (WEP, WPA/WPA2), and VPN/HTTPS can mitigate security risks
  • Restricting access to known MAC addresses also enhances security

Intermittent Connectivity in Mobile Devices

  • Mobile devices may have intermittent connections to Wi-Fi or the Internet
  • Data must be buffered to prevent loss during periods of connectivity
  • Data transfer mechanisms must handle frequent generation/receipt of data during intermittent connections

Energy-Constrained Mobile Devices

  • Mobile devices have limited power and thermal budgets due to small size, lack of fans, and restricted surface area
  • Battery life is a key constraint due to limited power storage, complex data management, and security requirements
  • Platform power and optimization can mitigate energy-constrained challenges
  • User experience and power management policies must consider hardware resources, user interaction, sensor inputs, and computational/protocol optimizations

Trends in Mobile Computing

  • The number of smartphone subscriptions worldwide is forecast to grow, surpassing six billion
  • China, India, and the United States have the highest number of smartphone users
  • Enhanced user experience, improved technology, and increased connectivity/computing options are driving the move to mobile computing
  • Mobile devices now feature improved battery life, faster processors, user-friendly materials, power-efficient displays, and high-bandwidth networks

This quiz covers the security risks associated with mobile systems, including messaging systems, connection channels, software vulnerabilities, and malicious software. It also explores mitigation options such as user authentication, encryption methods, and secure internet access.
