In a building intercom mobile communication network, all communication between the mobile station and the fixed network occurs through the wireless interface. However, since this interface is open, it poses significant risks. Attackers can exploit vulnerabilities in the wireless interface to intercept, eavesdrop on, or even tamper with the communication channels, thereby gaining unauthorized access to sensitive information. This could involve modifying, inserting, deleting, or retransmitting messages to spoof mobile user identities, deceive network terminals, or disrupt services. Based on the nature of the attacks, they can generally be categorized into three main types: unauthorized access to data, unauthorized access to network services, and threats to data integrity.
### 1. Unauthorized Access to Data Attacks
The primary goal of unauthorized data access attacks is to obtain user data and/or signaling data transmitted via the wireless interface. Several methods are commonly used:
- **Eavesdropping on User Data**: Intercepting and obtaining user communication content.
- **Eavesdropping on Signaling Data**: Gaining access to network management data and other critical information.
- **Wireless Tracking for Active Attacks**: Collecting mobile user identity and location information for tracking purposes.
- **Passive Transport Stream Analysis**: Inferring user communication content and purpose.
- **Active Transport Stream Analysis**: Attempting to gain access to internal system information.
### 2. Unauthorized Access to Network Service Attacks
In this type of attack, attackers impersonate legitimate mobile users to fraudulently access network services and evade payments. They may also use counterfeit mobile identities to enjoy free network services at the expense of others. Specific behaviors include:
- Impersonating legitimate users to access network services.
- Creating counterfeit service networks.
- Misusing authentication parameters to pose as legitimate users.
- Abusing user privileges to access services without payment.
- Misusing network services for illegal profit generation.
### 3. Threats to Data Integrity Attacks
Data integrity threats target both user data streams and signaling data streams in the wireless interface. Attackers aim to deceive data recipients by altering, inserting, deleting, or retransmitting these data flows. The scope of these attacks extends beyond the wireless interface to include communication interfaces between Base Station Subsystems (BSS) and Mobile Switching Centers (MSC). Key manifestations include:
- Manipulating user data streams to gain unauthorized network service access or disrupt communications.
- Modifying signaling data flows to interfere with communications or gain illicit access.
- Spoofing communication participants to deceive the network.
- Manipulating downloadable applications to interfere with mobile terminal operations.
- Disrupting the normal functioning of the mobile terminal.
- Tampering with data stored in network units to gain improper access rights.
### 4. Post-Service Repudiation Attacks
Post-service repudiation attacks occur after communication has taken place, where parties deny participation or responsibility to avoid payment or accountability. Examples include:
- Denying payment from senders.
- Refusing to pay for message services sent by recipients.
- Evading responsibility for receiving message services.
In radio communication networks, numerous insecurities exist, including wireless eavesdropping, identity impersonation, data falsification, and denial of service. These vulnerabilities directly impact the overall security of the community. Addressing these issues requires concerted efforts from manufacturers and developers to enhance network security measures and protocols.
By implementing robust encryption, authentication mechanisms, and continuous monitoring systems, we can significantly reduce the risk of unauthorized access and data breaches. Additionally, fostering awareness among users about safe practices can further strengthen the network's resilience against malicious activities. Continued research and innovation will play a crucial role in mitigating these challenges and ensuring the long-term security of building intercom mobile communication networks.
