IRJET- Secure Database Management and Privacy Preserving in Cloud ServerIRJET Journal
This document discusses privacy and security concerns regarding database management and data storage in cloud servers. It proposes a solution using cryptosom generation to securely communicate with multiple cloud servers. The key points are:
1) Privacy and security are major concerns for organizations storing data in the cloud as data is no longer under their direct control.
2) The proposed method uses cryptosom generation and identity-based encryption to hide a user's identity and assign encryption keys, improving security of communications with cloud servers.
3) A proxy re-encryption scheme is also described that allows third parties to modify an encrypted ciphertext for one user so that it can be decrypted by another user, without revealing the secret value.

SECURITY FOR SOFTWARE-DEFINED (CLOUD, SDN AND NFV) INFRASTRUCTURES – ISSUES A...csandit
This document discusses the security challenges of software-defined infrastructures including cloud, SDN, and NFV technologies. It outlines several issues such as insecure interfaces/APIs, malicious insiders, account hijacking, virtualization vulnerabilities, and service interruptions for cloud computing. For NFV, the key challenges discussed are hypervisor security issues that could allow attackers to access VMs and compromise the entire infrastructure. The document argues that these technologies introduce both traditional security risks as well as new technology-specific risks, and that a software-defined security approach is needed to address challenges across integrated cloud, SDN, and NFV platforms.
This architecture proposes a hybrid cloud-based firewalling approach to improve performance and reliability. The architecture has both a physical firewall and virtual firewalls in the cloud. Traffic is redirected from the physical firewall to the virtual firewalls in the cloud when the physical firewall becomes overloaded. This improves computational power by leveraging the resources of the cloud. Experimental results showed the hybrid approach improved latency, memory usage, and CPU performance compared to only using a physical firewall.

The document discusses enhancing data security in cloud computing using an addition-composition fully homomorphic encryption scheme. It begins by reviewing prior work on homomorphic encryption schemes, including Gentry's seminal work constructing the first fully homomorphic encryption scheme based on ideal lattices. It notes limitations of prior schemes in terms of computational strain. The document then proposes a new encryption scheme that uses both addition and composition operations to lessen computational strain while supporting faster encryption, larger ciphertexts, and versatility. The scheme is implemented in Java and tested on a basic hardware configuration, showing it enhances data security in cloud computing.
Mobile GIS architecture involves GPS receivers, navigation systems, satellite communication, GIS servers, databases, and mobile/desktop clients. The client sends requests to the server, which retrieves data from its database and sends a response. This communication occurs over a local or private network or the internet.
Cloud GIS has three service models: Software as a Service (SAAS) provides applications via thin clients; Platform as a Service (PAAS) deploys applications using data platforms; Infrastructure as a Service (IAAS) involves configuring all hardware and software.
There are four cloud deployment models: Public cloud for general public access; Private cloud for a single organization; Community cloud for groups agreeing on access; Hybrid cloud
Cloud computing provides various advantages such as reduced costs, improved scalability, mobility and collaboration. However, migrating to the cloud also presents some challenges including security concerns, vendor lock-in, integration issues, and loss of control over IT resources. A successful cloud migration requires careful planning and execution of key stages - planning the project, executing the migration, and monitoring outcomes. It is also important to start small, trust cloud vendors to protect data, maintain user identity management, and plan for potential latency and outages.

Project Deliverable 5: Network Infrastructure and Security
CIS 499 – Information Systems Capstone
November 25, 2018
Project Scope
The project will comprise of a network design to meet Acme Corporation network infrastructure requirements. The network should accommodate occasional guest users of up to 10 users. The network design will incorporate an FTP server that will use for sharing files. The project should involve separate subnet for guest and LAN networks; the guest network should be restricted to access only FTP service on the FTP server while all other access to the LAN network will be blocked. The project will also involve IP Network Design as well as identification and configuration details of the hardware utilized (Switches and Routers). Included in the network design is the implementation of a Wireless LAN (WLAN) that minimizes the management effort to configure and manage while allowing effective data transmission between the Wireless Application Protocols (WAPs).
Network design
The network will use a star topology where it provides centralized handling of the network and its’ associated security. Each of the floors of the building will have a central server which host switches that link the different rooms via ethernet cables. Each of the rooms will have a switch that is linked to the central server's router. The servers will be linked via fiber optic cables. The ethernet cables will be utilized for connecting individual devices to their associated switches. The network design will involve the utilization of both wired and wireless media. The wireless media will allow for a network connection for portable devices like tablets, cell phones, and laptops.
The switch links allow the traffic getting into the Acme’s LAN from the MAN not to be congested. As more tablets are utilized in the company, the WLAN bandwidth increases significantly to each room. This requires that the WAPs supporting the 802.11n protocol as well as faster 802.11ac standard require additional power. As a result, switches with PoE+ give the required power. These Switches utilize the existing Category-6 cable (Ethernet cables) that allow for remote administration and configuration (Karris, 2009).
Virtual LANs (VLAN) will be used to enables the network administrator to group users into shared broadcast domains irrespective of their physical position in the internetwork. For instance, computer devices utilized by employees on two different floors may be placed on the same VLAN. The staff has their VLAN while the Guest VLAN is used by guests when using wireless access points.
The company's network perimeter that detaches it from the Internet comprises of two border core routers. The border routers should then link to the Virtual Private Network (VPN) Gateway. The Routers link to the servers, wireless access points and switches as well as the LAN (internal network)..

According to a new Gartner report1, “Around 10% of enterprise-generated data is created and processed outside a traditional centralized data center or cloud. By 2022, Gartner predicts this
figure will reach 75%”. In addition to hosting new 5G era services, the other major network operator driver for edge compute and edge clouds is deploying virtualized network infrastructure, replacing many dedicated hardware-based elements with virtual network functions (VNFs) running on general purpose edge compute. Even portions of access networks are being virtualized, and many of these functions need to be deployed close to end users. The combination of these infrastructure and applications drivers is a major reason that so much of 5G era network transformation resolves around edge cloud distribution.
The digital transformation underway is accelerating, enabling new business opportunities both for telecom operators and for enterprises from other industries. The main drivers are the need for increased efficiency, flexibility and new business models enabled by the introduction of 5G and increased adoption of cloud technologies. New services can be expected to be deployed at an unprecedented pace.
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. Key characteristics of cloud computing include broad network access, resource pooling, rapid elasticity, and measured service. Cloud computing provides many advantages such as lower costs, improved performance and collaboration, universal access, and unlimited storage. However, it also has disadvantages like reliance on a stable internet connection, potential security and reliability issues, and limited features compared to desktop software.
RSA Insurance executed a large data migration project to modernize its infrastructure and enable cloud-first strategies.

The concurrency utilities package aims to make concurrent programs clearer, shorter, faster, more reliable, scalable, easier to write, read and maintain.
Defining a Summative Usability Test for Voting Systemswhite paper
This document outlines a proposed approach for conducting a summative usability test of a voting system to evaluate whether it meets specified usability requirements. The test is intended to identify failures in effectiveness, efficiency, and satisfaction rather than diagnose their causes. Key elements that must be defined include the purpose of the test, voting system, user tasks, data collection, and how results will be analyzed. Gaps are noted in establishing specific usability benchmarks and criteria for voting systems to pass or fail the test.
This document summarizes research conducted to develop usability performance benchmarks for voting systems to be included in the Voluntary Voting System Guidelines (VVSG). The research established a standardized testing methodology to measure usability across different voting system technologies. Over 450 test participants used four different voting systems and their interactions were analyzed to determine accuracy, completion rates, and error rates. The results were used to propose benchmark values for three usability measures that all systems must meet: a Total Completion Score of 98%, a Voter Inclusion Index of 0.35, and a Perfect Ballot Index of 2.33. The benchmarks and testing methodology are intended to improve the usability of future voting systems.

Cloud Computing for National Security Applications
1. CLOUD COMPUTING FOR NATIONAL SECURITY APPLICATIONS
A DATALINE WHITE PAPER
INTRODUCTION
Through collaboration with leading industry partners, Dataline is integrating an end-to-end
solution for secure cloud computing. Called Service Oriented Architecture – Real Time (SOA-
R), this solution integrates:
• Real-time services oriented architecture;
• Multi-tiered, high-performance storage;
• Event driven automated workflows;
• Mission specific applications and web services;
• Highly reliable, virtualized, hardware infrastructure;
• Efficient wide area networking with accelerate geosynchronous satellite IP throughput; and
• Information access through secure Mobile Adhoc Networking.
SOA-R provides the benefits of cloud computing and secure ad-hoc mobility in a modular,
standards-based implementation framework. By exploiting the advantages of a service oriented
approach, web services and interfaces specific to the national security business domain are being
developed and enhanced for deployment from and interface with a cloud computing
infrastructure. By doing this, Dataline, in concert with its partners, can provide leading edge
solutions without the risk typically associated with early adoption of leading edge technologies.
Like cloud computing, SOA-R has dual meanings. Whereas cloud computing refers to both a
platform and type of application, SOA-R refers to a solution framework and domain specific
solutions. To help understand these twin dualities consider the following descriptions:
• A cloud computing platform dynamically provisions, configures, reconfigures, and de-
provisions servers as needed. In a SOA-R framework, the provisioning, configuring,
reconfiguring and de-provisioning of servers is driven by national security domain specific
rules, metrics and mission guidelines
• Cloud applications are applications that are extended to be accessible through the Internet
from large datacenters and powerful servers that host Web applications and Web services.
SOA-R applications are extended to be accessible through highly secure virtual private
networks (VPN) tunnels and secure private networks (e.g. NIPRnet and SIPRnet). SOA-R
applications are typically composite applications, served from powerful servers, and
provided through Web Services from multiple organizations and datacenters.
P a g e | 1 of 9
2. The SOA-R framework uses event-driven workflows to provide:
• Intra-workflow component reuse;
• Faster workflow execution;
• Distributed/parallel workflow execution;
• Normalizes workflow design;
• Enhanced business process interoperability;
• Enhanced information sharing;
• Ability to implement more sophisticated IT architectures;
• Reduces ad-hoc workflows; and
• Easier business process redefinition.
Figure 1 - SOA-R leverages the Event Driven Services Oriented Architecture first developed and deployed by
Great-Circle Technologies 1
SOA-R Solution Framework
The deployment of a secure cloud computing platform to support national security missions
requires an integrated solution across the following specific functional areas:
• Secure and highly scalable datacenters (Northrop Grumman, Dataline)
• Services Oriented Architecture and Mission Relevant Applications (GCT, IBM, Dataline)
• Hardware and software virtualization (IBM, Google, VMware) 2
• Secure Global and regional networks
• Secure wireless ad-hoc networking and network clients (Harris, L-3, Cisco, Dataline)

“Merlin and Minerva Story Map”, Great-Circle Technologies, 2007

We are including middleware, input/output and network virtualization in this requirement as well.
P a g e | 2 of 9
3. Northrop Grumman’s Mission Systems sector is one of the premier integrators of complex,
mission-critical systems. The sector develops and sustains systems that enable the Department of
Defense, Department of Homeland Security and the intelligence community to execute missions
at all levels: tactical, operational and strategic. Northrop Grumman is also the industry leader in
secure messaging systems, providing accreditable systems that process the most sensitive data of
the defense and intelligence communities. Northrop Grumman is the only company that can
deliver systems that send secure messages from one source to many addresses located across
multiple security enclaves. As an example of their capability, as the prime contractor for the
Army's Force XXI Battle Command Brigade and Below (FBCB2) program, Mission Systems is
replacing paper maps and voice radio communications with digital capabilities. As a large-scale
integrator, Northrop can provide its ability to design, deliver and operate mission critical end-to-
end IT infrastructures to the SOA-R team.
As an IBM Premier Partner, Dataline serves as the server, storage and middleware technology
integrator for SOA-R implementations. In this role, Dataline provides the server hardware,
storage technology, virtualization technology, SOA middleware and infrastructure management
middleware for the core cloud computing platform. In collaboration with Great-Circle
Technologies, Dataline designs and implements the enterprise service bus, all required storage
tiers and the cloud hardware and application provisioning strategy.
Figure 2 - Example high level cloud architecture
SOA-R also features an IBM WebSphere DataStage based Real Time Integration Architecture
(RTIA). This solution component features an event-driven, message-based and trigger based
infrastructure for the cost-effective integration of multiple applications. WebSphere DataStage
can operate in real-time, capturing messages or extracting data at a moment's notice on the same
platform that also integrates bulk data. This provides a key advantage over implementations that
require the use of two separate products to achieve the same functionality. This architecture
facilitates:
• Real-time performance.
• Scalability (number of nodes, communicating applications and fault tolerance).
P a g e | 3 of 9
4. • Construction of integration objects across applications, databases and systems without
generating or having to manage code separately.
• Elimination of any requirement of altering or compromising the modularity of existing
system by decoupling.
• Users and owners of applications / systems retaining control of their systems by not placing
Real Time Integration (RTI) functionality in line with their application code.
• Easy maintenance on production front.
• Low cost rework at the end of the development cycle. 3
Great-Circle Technologies serves as the subject matter lead on most SOA-R implementations. In
this crucial position, GCT designs all domain area workflows and selects specific applications
for use within the event-driven SOA architecture. GCT’s core expertise is in providing
innovative solutions that bridge the “best value” of standards-based commercial off-the-shelf
technologies (COTS/SCOTS) with existing government-owned technologies (GOTS). Key to
their success has been an ability to tailor pragmatic mission-oriented solutions that utilize
advanced geospatial intelligence technologies.
In cloud implementations, Hadoop, an open source implementation of the Google File System, is
the SOA-R preferred framework for running large data processing applications. This approach
allows the creation and execution of applications using Google’s MapReduce programming
paradigm, which divides the application into small fragments of work that can be executed on
any node in the cloud computing cluster. It also transparently supports reliability and data
migration through the use of a distributed file system. Using Hadoop, the cloud can execute
parallel applications on a massive data set in a reasonable amount of time, enabling
computationally-intensive services such as retrieving information efficiently, customizing user
sessions based on past history, or generating results based on Monte Carlo (probabilistic)
algorithms. SOA-R Team implementations are also well positioned to leverage any innovations
flowing from the IBM-Google cloud computing collaboration. 4
Since the SOA-R framework is designed to support national security missions, SOA-R solutions
typically leverage government provided global and regional communications networks. To do
this efficiently, SOA-R uses two key Dataline technologies: SkipWare® and SCPS-M™. These
technologies accelerate IP throughput over a geosynchronous satellite by a minimum of 17x the
rate of standard TCP. Improvement ratios increase significantly when run over errored and
asymmetric links. These protocols also achieve bandwidth efficiencies in excess of 90%, before
payload compression. Because SkipWare® and SCPS-M™ are designed to operate in a gateway
model, it is not necessary to deploy them on every remote client machine. A single gateway
serves the entire LAN, allowing for simple, unobtrusive integration into the network. Smart
congestion controls and transparent bridging features make these protocols true plug-and-play
technologies. SkipWare and SCPS-M are also designed to interoperate with other common

5. networking protocols, including TCP, DVB and SCPS-TP. Because SkipWare and SCPS-M are
based on IETF-standard TCP, all community experience and diagnostic tools associated with
TCP can be also applied to SkipWare.
Dataline has years of experience leveraging these global networks through its Data
Communication Device. With the addition of NSA approved Type 1 encryption, classified IP
connectivity can be provided through Ethernet, serial, wireless, cellular or satellite uplink within
an IPSEC VPN tunnel. This Everything on IP (EoIP) infrastructure provides direct email, IP-
based voice or video, mapping, network drive access and “behind-the-firewall” Internet access as
necessary.5 Access to web services also provides mash-up capability as well. Information can
also be pushed via subscriptions or event-driven SOA workflow processes.
SOA-R solutions can also leverage the CISCO mobile ad hoc networking solution as a
component. These networks are emerging as a means for delivering the benefits of IP networking
to users operating beyond the reach of a fixed network. In ad hoc networks mobile nodes
associate on an extemporaneous or ad hoc basis. Ad hoc networks have a number of
distinguishing characteristics when compared to conventional networking solutions:
• Self Forming: nodes that come within radio range of each other can establish a network
association without any pre-configuration or manual intervention
• Self Healing: nodes can join or leave on a rapid basis without impacting operation of the
remaining nodes
• No Infrastructure: in an ad hoc network, mobile nodes form their own network, and
essentially become their own infrastructure
• Peer to Peer: traditional networks typically support end systems operating in client-server
mode. In an ad hoc network, mobile nodes can communicate and exchange information
without prior arrangement and without reliance on centralized resources
• Predominantly Wireless: historically networks have been mostly wired, and enhanced or
extended through wireless access. The ad hoc environment is essentially wireless, but can be
extended to support wired resources
• Highly Dynamic: mobile nodes are in continuous motion and ad hoc networking topologies
are constantly changing.
Collectively, these characteristics will enable ad hoc networks to deliver timely information to a
new and under-served class of users. Ad hoc networking solutions can be applied to virtually any
scenario that involves a cadre of highly mobile users or platforms (which may include stationary
devices as well), a strong need to share IP-based information, and an environment in which fixed
infrastructure is impractical, impaired, or impossible. SOA-R ad hoc networking uses the Cisco
RFC 4938 extensions for Ethernet-based communications between a router and a device such as
a mobile radio that operates in a variable bandwidth environment and has limited buffering
capabilities. These extensions provide a point-to-point over Ethernet (PPPoE) session-based
mechanism for sharing radio network status such as link quality metrics and establishing flow
control between a router and an RFC 4938-capable radio. An RFC 4938 radio initiates a Layer 2

6. PPPoE session with its adjacent RFC 4938 router on behalf of every router/radio neighbor
discovered in the network. These Layer 2 sessions are the means by which radio network status
for each neighbor link gets reported to the router. The radio establishes the correspondence
between each PPPoE session and each link to a neighbor. Cisco’s RFC 4938 solution enables
network-based applications and information to be quickly and reliably transported over
directional radio links. Fast convergence and optimal route selection ensure satisfactory delivery
of mission-critical, delay-sensitive traffic. 6

7. National Security Mission Relevance
According to Google CEO Eric Schmidt "Cloud computing is the story of our
lifetime….Eventually all devices will be on the network." He also, however, stated that with the
exception of security requirements, "there's not that much difference between the enterprise
cloud and the consumer cloud" 7 . SOA-R addresses that important difference.
Cloud computing advantages include:
• Location of infrastructure in areas with lower costs of real estate and electricity
• Sharing of peak-load capacity among a large pool of users, improving overall utilization
• Separation of infrastructure maintenance duties from domain-specific application
development
• Separation of application code from physical resources
• Ability to use external assets to handle peak loads (no requirement to engineer for highest
possible load levels)
• No requirement to purchase assets for one-time or infrequent intensive computing tasks 8
In today’s operational, fiscal, and environmentally friendly environment, all national security
agencies are being driven to look at the advantages offered by cloud computing. SOA-R answers
that need. When the SOA-R framework is engineered into a domain-specific solution, all
technical, operational, procedural and environmentally friendly agency information technology
requirements can be addressed in a service oriented, event-driven, globally networked, secure
infrastructure. Defense, homeland security, justice and intelligence agencies all can benefit by
considering SOA-R as the core of their transition to cloud computing.
