A Location Based Cryptosystem For Mobile Devices Using Improved Rabin AlgorithmEditor IJMTER
As per the recent studies, the volatile growth has been seen in the use of mobile devices as
the supporting technology for accessing Internet based services, as well as for personal
communication needs in networking. Various studies indicate that it is impossible to utilize strong
cryptographic functions for implementing security protocols on mobile devices. Our research negates
this. Explicitly, a performance analysis focused on the most commonly used cryptographic protocols
based on the location address (latitude & longitude) of the user for mobile applications and projected
provably secure authentication protocol that is more efficient than any of the prevailing
authentication protocol is being used by the network security methods. Understanding the use of
public key cryptography which makes potential use of discrete logarithms problem. The security of
ECC depends on the difficulty of Elliptic Curve Discrete Logarithm. To provide secure
communication for mobile devices, authenticated protocol is an important primitive for establishing
trusted connection. In this paper, it has been shown that the location based system using improved
Rabin Algorithm provides a better security and acquires much less energy consumption than the
existing authentication protocols.
Evaluation of enhanced security solutions inIJNSA Journal
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
Defence-in-Depth Strategy and integration of biometric solution in 802.11i. Comprehensive in-depth
comparative analysis of each of the security mechanisms is driven by review of related work in WLAN
security solutions.

Network security is a dynamic art, with dangers appearing as fast as black hats can exploit vulnerabilities. While there are basic “golden rules” which can make life difficult for the bad guys, it remains a challenge to keep networks secure. John Chambers, Executive Chairman of Cisco, famously said “there are two types of companies: those that have been hacked, and those who don’t know they have been hacked”. The question for most organizations isn’t if they’re going to be breached, but how quickly they can isolate and mitigate the threat. In this paper, we’ll examine best practices for effective cybersecurity – from both a proactive (access hardening) and reactive (threat isolation and mitigation) perspective. We’ll address how network automation can help minimize cyberattacks by closing vulnerability gaps and how it can improve incident response times in the event of a cyberthreat. Finally, we’ll lay a vision for continuous network security, to explore how machine-to-machine automation may deliver an auto-securing and self-healing network.

Intrusion detection and anomaly detection system using sequential pattern miningeSAT Journals
Abstract
Nowadays the security methods from password protected access up to firewalls which are used to secure the data as well as the networks from attackers. Several times these types of security methods are not enough to protect data. We can consider the use of Intrusion Detection Systems (IDS) is the one way to secure the data on critical systems. Most of the research work is going on the effectiveness and exactness of the intrusion detection, but these attempts are for the detection of the intrusions at the operating system and network level only. It is unable to detect the unexpected behavior of systems due to malicious transactions in databases. The method used for spotting any interferes on the information in the form of database known as database intrusion detection. It relies on enlisting the execution of a transaction. After that, if the recognized pattern is aside from those regular patterns actual is considered as an intrusion. But the identified problem with this process is that the accuracy algorithm which is used may not identify entire patterns. This type of challenges can affect in two ways. 1) Missing of the database with regular patterns. 2) The detection process neglects some new patterns. Therefore we proposed sequential data mining method by using new Modified Apriori Algorithm. The algorithm upturns the accurateness and rate of pattern detection by the process. The Apriori algorithm with modifications is used in the proposed model.

Bluetooth is an essential wireless standard for short-distance and low-power wireless networks. Health
departments’ contact-tracing applications depended on Bluetooth technology to prevent infectious diseases
from spreading, especially COVID-19. The security threats of the Bluetooth-based contact-tracing
applications increased because an adversary can use them as surveillance tools that violate the user’s
privacy and revealpersonal information. The Bluetooth standard mainly depends on the device address in
its authenticated pairing mechanism (Secure Simple Pairing), which can collect with off-the-shelf
hardware and software and leads to a tracking attack. To avoid the risk of tracking based on this security
vulnerability in the Bluetooth protocol, we suggest a novel authentication protocol based on a non-
interactive zero-knowledge scheme to substitute the authentication protocol used in the Bluetooth standard.
The new protocol can replace the authentication protocol in the Bluetooth stack without any modification
in the device pairing flow. Finally, we prove the security of our proposed scheme against the man-in-the-
middle attack and tracking attack. A performance comparison with the authentication algorithm in the BLE
standard shows that our method mitigates the tracking attack with low communication messages. Our
results help enhance the contact-tracing application’s security in which Bluetooth access is available.

Security in Software Defined Networks (SDN): Challenges and Research Opportun...Editor IJCATR
In networks, the rapidly changing traffic patterns of search engines, Internet of Things (IoT) devices, Big Data and data centers has thrown up new challenges for legacy; existing networks; and prompted the need for a more intelligent and innovative way to dynamically manage traffic and allocate limited network resources. Software Defined Network (SDN) which decouples the control plane from the data plane through network vitalizations aims to address these challenges. This paper has explored the SDN architecture and its implementation with the OpenFlow protocol. It has also assessed some of its benefits over traditional network architectures, security concerns and how it can be addressed in future research and related works in emerging economies such as Nigeria.
NIST's work underpins most of today's top science and technology challenges, such as cyber-security, biometrics, voting equipment standards, and nanotechnology, just to name an important few.

Security and risk analysis in the cloud with software defined networking arch...IJECEIAES
Cloud computing has emerged as the actual trend in business information technology service models, since it provides processing that is both costeffective and scalable. Enterprise networks are adopting software-defined networking (SDN) for network management flexibility and lower operating costs. Information technology (IT) services for enterprises tend to use both technologies. Yet, the effects of cloud computing and software defined networking on business network security are unclear. This study addresses this crucial issue. In a business network that uses both technologies, we start by looking at security, namely distributed denial-of-service (DDoS) attack defensive methods. SDN technology may help organizations protect against DDoS assaults provided the defensive architecture is structured appropriately. To mitigate DDoS attacks, we offer a highly configurable network monitoring and flexible control framework. We present a dataset shift-resistant graphic model-based attack detection system for the new architecture. The simulation findings demonstrate that our architecture can efficiently meet the security concerns of the new network paradigm and that our attack detection system can report numerous threats using real-world network data.
Every 25 years or so, telecom networks get totally re-designed. The last big re-build came with the internet in the early 1990s. Now “IP networking” technology is giving way to another technology cycle known as “software defined networking”. SDN is a new architecture for telecom networks in which the emphasis shifts from hardware to software. It will be hugely disruptive because it fundamentally changes who controls the telecom network. In the report we predict some of the winners and losers.
This includes short description about modern computer network technologies like: 5G Technology, Artificial intelligence (AI), Augmented Reality and Virtual Reality, IoT, Edge/cloud computing, WIFI-6, SDN, SD-WAN, DevOps etc.
A review on software defined network security risks and challengesTELKOMNIKA JOURNAL
Software defined network is an emerging network architecture that separates the traditional
integrated control logic and data forwarding functionality into different planes, namely the control plane and
data forwarding plane. The data plane does an end-to-end data delivery. And the control plane does
the actual network traffic forwarding and routing between different network segments. In software defined
network the networking infrastructure layer is where the entire networking device, such as switches and
routers are connected with the separate controller layer with the help of standard called OpenFlow
protocol. The OpenFlow is a standard protocol that allows different vendor devices like juniper, cisco and
huawei switches to be connected to the controller. The centralization of the software defined network
(SDN) controller makes the network more flexible, manageable and dynamic, such as provisioning of
bandwidth, dynamic scale out and scale in compared to the traditional communication network, however,
the centralized SDN controller is more vulnerable to security risks such as DDOS and flow rule poisoning
attack. In this paper, we will explore the architectures, the principles of software defined network and
security risks associated with the centralized SDN controller and possible ways to mitigate these risks.

Chrono Defend: Time-Traveling Safeguards through NGFW Firewall InnovationSecurityGen1
As the digital landscape expands exponentially, a paradigm shift in cybersecurity has emerged – the NGFW (Next-Generation Firewall) heralds a new era of safeguarding data in the quantum realm. Drawing inspiration from the mysterious world of quantum mechanics, the NGFW Firewall Nexus is a technological marvel that harnesses the power of quantum computing to decode and decrypt threats at a speed that defies classical computing limits. Its encryption algorithms are the equivalent of a digital lock that can only be unlocked by the right quantum key, rendering cyber intruders powerless.
However, this massively connected environment created by 5G and edge-based
computing presents a new and highly vulnerable threat landscape with potentially more
significant security risks to consider as cloud, data and IoT threats merge. Adversaries will
be able to spread malware via IoT networks, disrupt core functions and use routers as IoT
botnets to launch DDoS attacks. In this scenario, protecting the legacy LTE network will be
as crucial as the standalone 5G networks – as while a few 5G networks will be built from
scratch; most will need to integrate and interoperate with existing technologies and
infrastructure. All this means that traditional, rule-based security systems will no longer be

Whitepaper - Software Defined Networking for the Telco Industry
1. SOFTWARE DEFINED NETWORKING
IN THE TELCO INDUSTRY
White paper
V1.0 - 11/10/2016
How could it improve cyber security?
What changes would it mean for network and telco employment?
2. Every year, maintaining the security of a network grows more and more
difficult. As networks become more complex (with more users, increased
traffic, a greater number of devices), threats to organisations are
becoming much more frequent, more targeted, and more sophisticated.
The telecoms industry is one which has been particularly fraught with an increasing volume of cyber
risks. According to research from the Ponemon Institute, in 2015 alone the industry lost around £6.3
million in cyber crime. What’s more, two of the UK’s largest telecommunications firms experienced
cyber attacks within a few weeks of one another.
In March 2016, a study from the Centre for Economic and Business Research (CEBR) was reported in the
Telegraph which surrounded the security of the telecoms industry. As part of the study, the economists
at the CEBR modelled how a real cyber-attack would affect a cross section of the British economy.
CYBER SECURITY IN TELCO
79%
..of security professionals working at enterprise
organisations claim that network security is more
difficult now than it was two years ago
3. In parallel with the growing threat of cyber security, Software Defined Networking (SDN) technology is
fast being adopted by telecoms carriers and service providers. This technology is key to scaling up the
network capacity and it's capability to fuel internet demands from the likes of:
cloud services
mobile-enabled services
live streaming
the internet of things.
The results of their research showed that the telecoms sector is highly vulnerable to attacks and breaches
due to the sensitive information held and the value of this data.
CYBER SECURITY IN TELCO
£52.5m
British companies hold approximately..
worth of sensitive information, including financial
details and intellectual property.
The Emergence of SDN
4. In addition to scale, SDN is being implemented for it’s potential to reduce capital expenditure and operational
expenditure for Tier 1 telecoms providers. What’s more, it increases flexibility and efficiency due to its ability
to ramp up or ramp down network services on demand.
CYBER SECURITY IN TELCO
When designing and implementing SDN services and solutions, telecom carriers now have a great cyber
security opportunity to centralise, automate and improve attack detection and mitigation.
By separating the control and data planes, SDN is not restricted by physical devices to control and
manage network traffic flows. As such, with no physical barriers, SDN controllers can monitor traffic,
detect threats, and mitigate attacks anywhere in the network with the use of a centralised
software-based network security solution.
Improving Cyber Security using SDN
SDN enables network management to be decoupled from the data flow and,
by centralising the control segments of the network, network traffic can be
monitored and directed from a central point using software. Furthermore,
standardised API’s in newer SDN controllers enable the network to respond
to user and application demands in a faster and more efficient way.
“The key [to SDN enabled cyber security] is to implement a network security
solution that can take advantage of SDN’s dynamic nature.”
- LOUIS SCIALABBA IN SDN, SERVICE PROVIDER
5. The network defence solution can take advantage of the programmability of SDN to improve cyber security
for the entire network with enhanced network agility.
An SDN network can also automatically respond to changes in network behaviour. SDN can make it easier to
collect network usage information, which could support improved algorithm design used to detect intrusions,
threats and attacks. A new generation of applications can harness better-informed SDN agents to improve
traffic anomaly detection and mitigation in networks, which may allow them to stop malicious intruders
before they enter the critical areas of the network.
According to Jennia Hizver, Consulting Practice Security Researcher and Consultant at AT&T, in her
article entitled “The security benefits of Software Defined Networking”, “the biggest benefit of
SDN-enabled security is that it presents an opportunity for intelligent response on a granular basis by
selectively blocking malicious traffic while still allowing normal traffic flows”.
Dave Shackleford of Voodoo Security states in his article “How SDN will enable automated network
security” that SDN promises centralised control and traffic management, which can result in automated
network security and security-defined network routing that could transform the way we secure the
network and the applications or data running across it. For example, SDN security applications are
capable of acting on any anomalies by diverting specific network flows to special security enforcement
points or security services (e.g. firewalls and intrusion detection/prevention systems), thus enabling
untoward events and threats to be monitored in highly dynamic IT environments, with the potential
for achieving greater network security visibility.
Moreover, with SDN, it is possible to define a virtual network architecture that closely maps the logical
architecture of an application, thus modelling all application items on a single private virtual network.
As such, the rules for appropriate and inappropriate communication among the parts in the system,
and the rules for the private network communication with the rest of the broader network systems
can be outlined clearly – which wasn’t possible with previous traditional network architectures
(Peter Christy, Research Director at 451 Research).
On the other side of the coin, there are also potential SDN-related security concerns which have been
discussed in the public domain. As with any new technologies introduced, further security measures -
policies, better authentication, authorisation and access procedures, etc. – needs to be implemented
to safeguard systems and data security in an SDN network deployment.
CYBER SECURITY IN TELCO
What the Experts are Saying
6. With all these exciting new potentials, how does SDN-enabled security transform future network and
telco roles?
According to Kelly Jackson Higgins, Executive Editor of DarkReading.com, traditional network security
roles will eventually operate using software-defined networking (SDN) and virtualisation skill sets. “It’s
a logical evolution: as the network and its services become more software-driven and virtualised, it
only makes sense that security would join the party” and “a new software-defined security model
also will require a cultural shift”.
Rather than security professionals updating each firewall separately, firewall rules could be pushed to
all devices via SDN “in a matter of seconds,” (Warren Wu, Senior Director of Products at Fortinet). Network
engineers will need to upskill and learn how to work with SDN controllers, and how to manage the
interaction with applications and orchestration systems that connect via APIs, as well as the security
control aspects that comes with it.
CYBER SECURITY IN TELCO
How does SDN-enabled security transform future network and telco roles?
7. Will roles such as “SDN/NFV Network Security Architects”, “SDN Protective
Monitoring Analysts” and/or “SDN Security Developer” roles start
dominating our IT Recruitment market?
At aap3, we believe that there will be a changing trend in the marketplace, away from Network and
Security engineers, with the traditional skills based on network hardware configuration. What's more,
there will be a requirement for a blend of skills that includes an understanding of coding and
development languages for software configuration. That’s not to say that these “traditional” skills will
become redundant, as they still form the core of networking and network security, but that a change
in skill set, or perhaps an entirely new job type, will be needed to cope with future technology demands.
For businesses, this might mean that they have to invest in external training for their existing staff, whilst
re-evaluating their skills requirements for new positions. A decision will have to be made between
upskilling existing employees, replacing with new skill sets, or potentially increasing the employee base
temporarily to bring these new skills into the business.
Alternatively, businesses can leverage external suppliers to provide technical resources to help them
bridge the gap between current and future technologies, providing professional contractors or managed
services resources to deliver upgrades and manage and maintain network infrastructure without the
need for potentially expensive in-house expertise.
