Ii jamming jamming unlike eavesdropping and traffic

II. Jamming
Jamming, unlike eavesdropping and traffic analysis, will fully interrupt legitimate user communications.
Figure 5b depicts a jamming attack. The malicious node can cause deliberate intrusion, causing
legitimate users' data communications to be interrupted. Jamming can also make it impossible for
approved users to access radio services. Active attack solutions are usually detection-based.
III. Dos and DDos
An adversary's network resources can be depleted by DoS attacks. DoS is a network availability breach
caused by a security attack. A DoS assault can be launched using jamming. When there are several
distributed adversaries, a DDoS can be created. A DDoS model is shown in Figure 5c. Both DoS and DDoS
are active attacks that can be used at various layers. Detection is currently used to identify DoS and DDoS
attacks. DoS and DDoS will undoubtedly become a major challenge for operators as the penetration of
large devices in 5G wireless networks increases. In 5G wireless networks, DoS and DDoS attacks will use a
large number of connected devices to target the access network. A DoS attack can be classified as either
a network infrastructure DoS attack or a device/user DoS attack, depending on the target. A DoS attack
on network infrastructure can target the signalling plane, user plane, management plane, support
systems, radio resources, logical and physical resources, and so on. DoS attacks on devices and users can
target battery, memory, disc, Processor, radio, actuators, and sensors.

IV. MITM
The attacker secretly takes control of the communication channel between two legitimate parties in an
MITM attack. The MITM attacker has the ability to intercept, alter, and overwrite communication
messages sent between two legitimate parties. A MITM assault is depicted in Figure 5d. MITM is a form
of active attack that can be launched at various levels. MITM attacks, in particular, are designed to
jeopardize data security, integrity, and availability. MITM attack is one of the most common security
threats, according to Verizon's data investigation study. False base station based MITM is an attack in
which an attacker induces a legitimate user to build a link with a fake base transceiver station in a legacy
cellular network [42]. To avoid false base station-based MITM, mutual authentication between the
mobile device and the base station is usually used.
Network security in 5G and privacy solution in a systematic way
The new design, technologies, and use cases in 5G wireless networks introduce new security features
and specifications. Authentication (entity authentication, message authentication), confidentiality (data
confidentiality, privacy), availability, and honesty are the four types of security services covered
throughout this section.
