Security challenges in mobile communication systems

1. Open transmission medium

Wireless communication relies on open radio waves making it susceptible to eavesdropping, data interception and unauthorized access in which confidential information like calls, messages and data transmissions can be compromised. 

2. Device vulnerability

Mobile devices are attractive targets for malware and hacking due to their portability and personal data storage hence data theft, financial loss, identity theft and device malfunctions are at potential risks.

3. Data security and privacy

Mobile devices store most amounts of personal and sensitive data, making data security and user privacy paramount .Data breaches, can lead to identify theft, financial loss, and reputational damage.

4. Network infrastructure security

Complex network infrastructure with numerous access points creates vulnerabilities for attacks an operates and denial of services, data breaches and network manipulation can disrupt services and compromise user data.

5. Lack of user awareness

Many users are unware of mobile security risk best practices, making them vulnerable to attacks increased susceptibility to phishing scams, malware infections, and social engineering attacks.

6. Emerging technologies

New technologies like 5G,IOT and mobile edge computing introduce new attack vectors and security complexations increased attack surface and potential for sophisticated attacks targeting vulnerabilities in these technologies.

7. User authentications and authorization

Verifying user identities and granting appropriate access privileges in a mobile environments in challenging unauthorized access to devices, accounts and sensitives information can occur.
