5G-WLAN Security 151
With Software Defined Networking, the control logic is moved from the underlying
infrastructure to a controller in the control layer. With this, software will be implemented upon the central SDN controller to provide the consistent and efficient management over entire 5G networks. Hence, an SDN‐based authentication enabled
scheme using SCI transfer is designed to provide fast authentication in 5G networks.
In addition, seamless authentication during frequent handovers is achieved through
SDN‐based authentication.
7.4.1 WIFI-5G Security Challenges with Respect to a Large Number
of Device Connectivity
In general, there are two classes of security requirements in WiFi or the 5G network,
namely the mobile user’s privacy and data integrity protection. The most common
types of security challenges with increased device connectivity are [11,12]:
● Impersonation attacks: with this type of attack, the intruder pretends to impersonate
a legitimate user to attack the networks. This case is common at the gateways,
where the packet switch interoperates from one network (WiFi) to another
network (5G);
● Network security flaws: this is where authentication of the network (5G or WiFi) is not
provided to the end user. Hence, the intruder can pretend to be a legitimate user and
join in any of the networks from where malicious packets can be forwarded and
switched to the other networks at WiFi‐5G gateways;
● Anonymity gains: once the intruder gains the information on the end users habits.
then it is easy to compromise the network through calling patterns that can be used
against the end user;
● Attacks against confidentiality: the intruder makes use of the loop holes in either
circuit switched or packet switched network architecture (WiFi or 5G networks). In
addition, the flaws in the communication protocols between the networks and the
end user can trace out to attack the network by comprising weak confidentiality
algorithms. Examples of this type are Brute force attacks, cryptanalysis‐based attacks
and non‐cryptanalysis attacks;
● Denial of Service (DoS) attacks: the intruder floods the network to disable the end
users and then accesses the network either by performing the attack using physical or
logical intervention. Denial of service attack is the most prominent security attack on
wireless networks.
7.4.2 Security Challenges in 5G Networks and WiFi
[13] clearly describes the security issues that exist in 5G Networks and WiFi. Since
similar network architecture (UMTS, LTE) with different modulation/ demodulation,
data rates and cell coverage area (sensing/transmission) are used in 5G networks, the
issues described in [13] will exist in 5G networks. The “Issue Type” and “Issue
Description” for security issues in 5G networks are clearly described in Table.7.1.
The possible security attacks in the packet‐switched based radio access network
(WiFi) are briefly described in (Table 7.2) below:
