Security Concerns in Mobile Networks
Mobile networks have traditionally relied on implicit trust among partners, but this approach has flaws. One-sided authentication means only users are authenticated by the network, not vice versa. Lack of transparency and insecure SS7 roaming interfaces also pose risks.
New Approach: Zero Trust Policy
The industry is moving towards a zero-trust policy where no one trusts anyone else. This includes networks, operators, and vendors. Security testing, audit, and compliance requirements are becoming essential.
Challenges in 5G Networks
- Extensive data collection
- Location tracking (devices and baseband)
- IoT vulnerabilities
- Network vulnerabilities
- Supply chain risks
Ways to Fix Them
- Implement zero-trust architecture
- Flawless implementation of security features according to specifications
- Test and audit networks regularly
- Continuous monitoring facilities
- Proper defense against denial-of-service attacks
Conclusion
New attacks will always emerge, but it’s essential to address existing vulnerabilities and implement robust security measures to prevent repeated attacks.
