Secured Intrusion Protection System through EAACK in MANETSijtsrd
Achieving reliable routing has always been a major issue in the design of communication networks, due to the absence of fixed infrastructure among which mobile ad hoc networks MANETs that can take control of the most adversarial networking environment, and the dynamic network topology the nature of open transmission media. In the MANETs these characteristics also more challenging to make the design of routing protocols. The network topology varies so to determining feasible routing paths for distributing messages in a decentralized is a difficult job. Factors such as the extensive distribution of nodes and open medium, variable wireless link quality topological changes, and propagation path loss become pertinent issues and make MANET unprotected to instructions. Thus, it becomes central to develop a systematic intrusion detection scheme to secure Mobile Ad Hoc networks from intruders. In this project, we put forward and applied an efficient IDS mechanism based on Enhanced Adaptive Acknowledgment EAACK especially made for MANETs which performs better than the earlier techniques such as AACK, TWOACK and Watchdog.

A NOVEL SECURITY PROTOCOL FOR WIRELESS SENSOR NETWORKS BASED ON ELLIPTIC CURV...IJCNCJournal
With the growing usage of wireless sensors in a variety of applications including Internet of Things, the security aspects of wireless sensor networks have been on priority for the researchers. Due to the constraints of resources in wireless sensor networks, it has been always a challenge to design efficient security protocols for wireless sensor networks. An novel elliptic curve signcryption based security protocol for wireless sensor networks has been presented in this paper, which provides anonymity, confidentiality, mutual authentication, forward security, secure key establishment, and key privacy at the same time providing resistance from replay attack, impersonation attack, insider attack, offline dictionary attack, and stolen-verifier attack. Results have revealed that the proposed elliptic curve signcryption based protocol consumes the least time in comparison to other protocols while providing the highest level of security.
Even in difficult places to reach, the new networking technique allows the easy deployment of sensor networks although these wireless sensor networks confront a lot of constraints. The major constraint is related to the quality of information sent by the network. The wireless sensor networks use different methods to achieve data to the base station. Data aggregation is an important one, used by these wireless sensor networks. But this aggregated data can be subject to several types of attacks and provides security is necessary to resist against malicious attacks, secure communication between severely resource constrained sensor nodes while maintaining the flexibility of the topology changes. Recently, several secure data aggregation schemes have been proposed for wireless sensor networks, it provides better security compared with traditional aggregation. In this paper, we try to focus on giving a brief statement of the various approaches used for the purpose of secure data aggregation in wireless sensor networks.
Co-operative Wireless Intrusion Detection System Using MIBs From SNMPIJNSA Journal
In emerging technology of Internet, security issues are becoming more challenging. In case of wired LAN it is somewhat in control, but in case of wireless networks due to exponential growth in attacks, it has made difficult to detect such security loopholes. Wireless network security is being addressed using firewalls, encryption techniques and wired IDS (Intrusion Detection System) methods. But the approaches which were used in wired network were not successful in producing effective results for wireless networks. It is so because of features of wireless network such as open medium, dynamic changing topology, cooperative algorithms, lack of centralized monitoring and management point, and lack of a clear line of defense etc. So, there is need for new approach which will efficiently detect intrusion in wireless network. Efficiency can be achieved by implementing distributive, co-operative based, multi-agent IDS. The proposed system supports all these three features. It includes mobile agents for intrusion detection which uses SNMP (Simple network Management Protocol) and MIB (Management Information Base) variables for mobile wireless networks.

As the popularity of mobile devices and wireless networks significantly increased over the
past years. The wireless adhoc network has now become one of the most vibrant and active
fields of communication and networking research. These networks are a new generation of
networks offering unrestricted mobility without any underlying infrastructure. As their
principle application is in disastrous environments, security is critical. Various challenges are
faced in the adhoc environment, mostly due to the resource poorness of these networks. One
man confront in the design of these networks is their vulnerability to security attacks. The
solutions for conventional networks are usually not sufficient to provide efficient adhoc
operations. Just because of its wireless nature of communication and lack of any security
infrastructure raise several security problems and threats.
In this paper, we briefly review the threats an adhoc network faces and the security goals to
be achieved. Moreover, it also presents existing security schemes used in wireless adhoc
networks in order to handle security threats.

IMPLEMENTATION OF A SECURITY PROTOCOL FOR BLUETOOTH AND WI-FI IJNSA Journal
This paper is mainly based on providing security to the wireless networks through which devices like Bluetooth gets connected. The Wi-Fi connections are also prone to various attacks these days. The protocols that are required to provide security to wireless networks can be implemented by creating a wireless scenario using the software Network Simulator. This paper illustrates a scenario to check the security protocol. As NS2 mainly has the implementation of routing protocols, a new protocol should be designed especially for security purpose. This is done by following many tutorials to get a minimum basic
knowledge of NS2, C/C++ coding. The security feature followed in the paper is encryption/decryption of the data that is being exchanged. Data should be ensured as and then there will be a perfect implementation of the protocol. So, the paper throughout concentrates on adding a new security protocol to NS2 and implementation of that protocol by providing a wireless scenario.

Advanced Security Management in Metro Ethernet NetworksIJNSA Journal
With the rapid increase in bandwidth and the introduction of advanced IP services including voice, high-speed internet access, and video/IPTV, consumers are more vulnerable to malicious users than ever. In recent years, roviding safe and sound networks and services have been the zenith priority for service providers and network carriers alike. Users are hesitant to subscribe to new services unless service providers guarantee secure connections. More importantly, government agencies of many countries have introduced legislations requiring service providers to keep track and records of owners of IP and MAC addresses at all time. In this paper, we first present an overview of Metro Ethernet (or Ethernet-To-The-Home/Business (ETTx)) and compare with various IP broadband access technologies including DSL, wireless and cable. We then outline major security concerns for Metro Ethernet networks including network and subscriber/end user security. Next we introduce state-of-the-art algorithms to prevent attackers from stealing any IP or MAC addresses. Our proposal is to use network management in conjunction with hardware features for security management to provide a secure and spoofing-free ETTx network. The key idea behind our proposal is to utilize network management to enforce strict (port, MAC, IP) binding in the access network to provide subscriber security. The paper then proposes an adaptive policy-based security controller to quickly identify suspected malicious users, temporarily isolate them without disconnecting them from the network or validating their contracts, and then carry the required analysis. The proposed controller identifies malicious users without compromising between accurate but lengthy traffic analysis and premature decision. It also provides the ability to make granular corrective actions that are adaptive to any defined network condition.
In our research work we are improving the performance of mobile ad hoc networks under jamming attack by using an integrated approach. The proposed work includes a network with high mobility, using IEEE Along g standard jamming attacks and countermeasures in wireless sensor networks

Traditionally, 802.11-based networks that relied on wired equivalent protocol (WEP) were especially
vulnerable to packet sniffing. Today, wireless networks are more prolific, and the monitoring devices used
to find them are mobile and easy to access. Securing wireless networks can be difficult because these
networks consist of radio transmitters and receivers, and anybody can listen, capture data and attempt to
compromise it. In recent years, a range of technologies and mechanisms have helped makes networking
more secure. This paper holistically evaluated various enhanced protocols proposed to solve WEP related
authentication, confidentiality and integrity problems. It discovered that strength of each solution depends
on how well the encryption, authentication and integrity techniques work. The work suggested using a

Understanding Cybersecurity Breaches: Causes, Consequences, and PreventionBert Blevins
Cybersecurity breaches are a growing threat in today’s interconnected digital landscape, affecting individuals, businesses, and governments alike. These breaches compromise sensitive information and erode trust in online services and systems. Understanding the causes, consequences, and prevention strategies of cybersecurity breaches is crucial to protect against these pervasive risks.
Cybersecurity breaches refer to unauthorized access, manipulation, or destruction of digital information or systems. They can occur through various means such as malware, phishing attacks, insider threats, and vulnerabilities in software or hardware. Once a breach happens, cybercriminals can exploit the compromised data for financial gain, espionage, or sabotage. Causes of breaches include software and hardware vulnerabilities, phishing attacks, insider threats, weak passwords, and a lack of security awareness.
The consequences of cybersecurity breaches are severe. Financial loss is a significant impact, as organizations face theft of funds, legal fees, and repair costs. Breaches also damage reputations, leading to a loss of trust among customers, partners, and stakeholders. Regulatory penalties are another consequence, with hefty fines imposed for non-compliance with data protection regulations. Intellectual property theft undermines innovation and competitiveness, while disruptions of critical services like healthcare and utilities impact public safety and well-being.

1.INTRODUCTION
The recent advances in wireless network technologies and the rising applications as web 2-0,
mobile TV and streaming content led to the standardization of the 3rd generation partnership
project (3GPP). The next generation wireless communication systems world wide standardized as
4G which has increased security and very much reliable communication. In terms of architectural
design 4G is more interoperability across the HetNet environments and also it is operate on the
TCP/IP architectural design procedure[3]. When 3rd generation communication is moving to the
4th generation communication, many organizations are repairing for their 4G such as
IEEE802.16m, International Telecommunication union (ITU), Vodafone, China mobile
communications and many next generation mobile network vendors like Motorola and
Samsung[2]. Now a days many definitions of 4G arises which provides a bandwidth of 1000
Mbps in mobile equipment and in normal 1Gbps. It is surrounding with heterogeneous networks
having number of Radio Access Technology and Radio Access network[1]. The enabling
technologies which is interconnected for 4G are orthogonal frequency division multiplexing,
vertical handover protocols and in advance multiple input and multiple output and cognitive radio
network are also included. Table 1 shows main threads and risk and design decisions of 4G is
given below.

The Wimax architecture has an access serving network to provide the service stations or mobile
stations which is a connection to network service provider. But the 3GPP LTE architecture has
two core networks such as GPRS and EPC network. The GPRS core network offer network
connections for existing RANs and Evolved packet core network to give network connections to
evolved RAN and 3 GPP IP Access.
2.1 IP Multimedia subsystem security architecture
The IMS (IP Multimedia subsystems) is an important overlay on top of the network infrastructure
like 3 GPP. It aims to protect the all IMS sessions in between the end-users and IMS servers. It
also offering it’s authentication and authorization mechanisms. There are two parts of IMS
security and are described below.
First-hop Security: It secures the first hop from the end-user to the proxy-call session
control function.
Network domain security: It protects the rest of hops between call session control
functions inside IME core.
2.2 Next Generation network security architecture
The next generation network security mostly secures the IMS security. It divided in to two
security domains.

Access view security: it secures the first hop for the end-user device to access the
network.
Core view security: It covers security within intra operated domain.
2.3 8-Security dimensions of 4G Network
The 8-security dimensions take care to measures implemented to counter threats and potential
attacks.
Figure 2: 8-Security dimension analysis
Access control which measures protection level against unauthorized use of network
resources.
Authentication which measures confirmation level for the identities of each entity using
the network.
Non-repudiation which prove the origin of the data or identifies the cause of an event or
action.
Data confidentiality is to ensure that data is not disclosed to unauthorized users.
Communication security is to allow information to flow only between authorized end
points.
Data integrity is to ensure the accuracy of data so it can be modified, deleted, created or
replicated without authorization and also provides an indication of unauthorized attempts
to change the data.
Availability is to ensure that there is no denial of authorized access to network elements,
stored information, Information flows, services and applications due to network-
impacting events.

Privacy is to provide for the protection of information that could be derived from the
observation of network activities.
3. 4G WIRELESS SECURITY ISSUES
3.1 Physical layer issues
Both WIMAX and LTE are subject to two key vulnerabilities at the physical layer. By
deliberately inserting man-made interference on to a medium, a communication system can stop
functioning due to a high signal-to-noise ratio. There are two types of interference that can be
carried out: (i) noise (ii) multicarrier. Noise interference can be performed using white Gaussian
noise (WGN). In the case of Multi-carrier interference, the attacker identifies carriers used by the
system and injects a very narrowband signal on to those carriers[4]. Interference attacks can be
easily carried out as the equipment and knowledge to carry out such attacks are widely available.
Our analysis indicates that interference is easy to detect using radio spectrum monitoring
equipments. Using radio-direction-finding tools, the interfering source can be traced[1]. In
addition, increasing the power of the source signal and using spreading techniques can increase
it’s resilience against interference. While the possibility of interference is significant, since it is
easy to detect and address, we believe it’s impact on the WIMAX/LTE network and users will be
limited[13].
3.2 WiMAX-MAC-Layer security issues
To establish initial access with base station then IEEE802.16[11] Radio interface standard
describes several steps in order for a mobile station, that includes seven steps. The steps are initial
ranging and time synchronization, upper level parameter acquisition, basic capabiliiities
negotiation, scanning and synchronization, mobile station authorization and key exchange,
registration with the serving base station and the last step by which connection established.
Among these steps five step involved non secure traffic and two other two steps involved secure
traffic exchange based on the device authentication standards of Wi-max[6].
3.3 Denial of service security issues
The DoS attack are a concern for Wi-max network. These attack can be initiated through simple
flooding attacking on authenticated management frames[2].
3.4 Wi-Fi security issues
Wireless LANs based on WI-FI technology have been available for more than a decade.
However, the WI-Fi technology has most often been used in homes and public places such as
airports, hostels, and shopping malls where security is seeming less critical, although the cost
benefits of Wi-Fi could be attractive to enterprise environments thanks to increased mobility,
lower operational costs, and flexibility. Accordingly, security researchers have focused on
security threats and solutions in Wi-Fi networks to make it applicable to the enterprise

environments. The original security mechanism of Wi-Fi called wired equivalent privacy (WEP),
had a number of security flaws arising from the mis-application of cryptography, e.g. the use
of RC4 stream cipher and CRC-32 authentication[3]. Regarding this, a comprehensive security
evaluation based on the ITU-T X.805 standard has been performed[9].To remedy the security
flaws of Wi-Fi, several solutions have been proposed. The Robust Security Network (RSN) for
the IEEE 802.Ix standard’s port based network access control is a layer-2 authentication
mechanism and specifies how EAP can be encapsulated in the Ethernet frames. RSA Laboratory
and Cisco have developed TKIP to mitigate the weakness of RC4 via frequent renewal of
encryption key[5].
3.5. Possible Threats on 4G
The 4G may face lot of possible security Risks. The various heterogeneous technologies access
the infrastructure, so potential security needed to secure technologies . Also it may collapse of the
entire network infrastructure when multiple service providers share the core network
infrastructure. In 4G wireless , end-user equipments can also become a source of malicious
attacks worms, viruses, calls and spam mails and so on. The spam over internet, the new spam for
VoIP results a serious problem like the today’s E-mail spam[2]. As like the above VoIP threats
other 3 more VoIP Threats are (1) spoofing that misdirects communications, modifies data, or
transfers cash from a stolen credit card number. (2) Standard input point registration hijacking
that substitutes the IP address of packet header with attacker’s own. (3) Dropping of private
conversation that intercepts and CRYPT arises IP packets.
4. PROPOSED 4G FOUR LAYER SECURITY MODEL
The proposed 4 layer security model integrated into the two frameworks, peripheral and core
which allows to explore new security concepts. In this model 3 separate security layers such as
network architecture security, network transport security and service and application security are
used. It is designed to provide coherent heterogeneous communication on a global scale and it
also provide continuous connectivity through the seem less operation of multiple mobile
networks. These are accessible by mobile nodes, providing features like cognitive radio and
vertical handover.

Peripheral network
Core network
Figure 3-Proposed four layer security model which is integrated in to the two frameworks
In this proposed model two frame works are used.
Peripheral frame work which runs on the mobile node and interacts with wireless
access networks.
Core framework which runs in a distributed fashion in the core infrastructure.
By this double organized frame work, a multi layer security system arises that interacts with
those two frameworks to provide a secure environment.

5. CONCLUSION
To better understand the security of 4G network we represent their different security accepts like
physical layer issues, WiMAX-MAC layer issues, QoS issues and 4G Wi-Fi security issue. This
study also discussed 8-security dimension of 4G network and represent possible threats on 4G.
By the proposed four layer security model we try to avoid unsecureness of next generation
wireless communication.
