To sum up,
Computer networks play a major role in the technology sphere. Recent years have seen the importance of ensuring that an organization’s network is connected. Computer networks are often associated with the increasing number of computers. Many companies and governments are taking measures to improve network security. Network security is still a major concern for many people despite these measures. This paper provides an overview of the security challenges that organizations face and possible solutions. The paper also highlights the newest network security principles, trends and procedures. As such, both performance and security are important considerations in the implementation of a networking system.
IntroductionCurrently we are able to send and receive data comprising electronic mail, audio or video merely through the click of a push button. The Internet has been the fastest-growing infrastructure of recent times. Numerous technological innovations have revolutionized the way we live. But, these new technological developments have made it difficult to protect data in a satisfactory manner. Due to the fact that many deals are now conducted via internet, it is important for transactions to be safe and secure. Network security is a major concern in the modern world. Networking is not just about protecting information. It also covers a variety of other fields.
In addition, new technologies such as mobile, cloud storage, E-commerce, and fin-tech require a more advanced telecommunication network. These solutions are used to store confidential data of individuals, so their security is a must. To ensure the economic and security of every republic, it is essential to protect and grow next-generation networks. The regime’s strategies and tasks require efficient next-generation telecommunication networks.
BackgroundThe Australian communications industry is a key enabler for economic and social development. Communication is essential for everyone. Although communications have been required in Australia since the beginning of time, the adoption and rapid growth of telecommunications has transformed business models. The main activities of telecommunications are: telecommunication services, infrastructure to implement the services (including cable and free TV), as well as telecommunications technologies. The Australian content distribution and production, such as film, television and print media.
Even though telecommunications has a negligible direct impact on Australia’s employment and economy, it is a major enabler for other socioeconomic sectors. Many industries rely on telecommunications to run their business. In the case of social media and e-commerce; the industries of information, communication and media are most affected.
In order to grow the Australian economy and other sectors, it is necessary to implement a Next Generation Telecommunication Network. Telecommunication Network Project (NGN) has set the following goals:
Implementation a faster accessible telecommunications system.
Acceptability of the user is important
Integrating the telecommunications network with existing networks.
Design OverviewNGN is a collection of network services and designs that are layered into a single architecture. The Netflow/IPFIX flow record provides an integrated approach to data transmission in the next generation network. The network is used to collect the transmission data using dedicated tools. Transmission analysis systems retrieve the data to perform billing, congestion detection, and network security. The provider edge retrieves the transmission data and sends it to the intrusion detection system. The provider-edge is an edge router that’s connected to a network. The intrusion detection system analyzes transmission data transmitted through the Provider’s edge and alerts if malicious or unauthorized transmissions are detected.
Network LayersService Provision layerTechnologies used at the service provision layer:
Voice over Internet Protocol
The Service layer is an abstract network layer. Its goal is to serve as a middleware for third-party systems and services at a higher application level. The service layer provides servers controlled by a provider of telecommunication networks. The APIs are retrieved by application-layer servers of the third-party provider. Service-layer interfaces are also available at minor resource levels.
Control Panel LayerTechnologies:
The control plane is that part of the system responsible for signal transmission. Control packets can be sent or initiated by a router. Control planes are used to manage and configure systems.
Three simple elements make up any telecommunications plan: the control, management and data planes. The data plane is aided by the control and management planes. The dataplane contains the signals that are sent in the current network. The management signal plane is an extension of the control signals. The three mentioned planes in standard telecommunications are implemented by the firmwares of switches and routing devices.
The control plane is removed from the hardware of the telecommunications network and integrated into the software. This allows the access of telecommunication networks programmatically. This makes it easier to manage the network.
Transport LayerTechnologies for Control Panel Layer
SwitchesThe OSI transport layer is responsible for the end-to-end communications through the network. The layered architecture of protocols, additional network devices and application procedures allows consistent communication across multiple hosts. It is the transport layer that has to provide quality and reliability for the end-user. It is also responsible for error-correction. Transport layer enables host to transmit or accept error-corrected packets, messages, information and data through network connection. The network is what facilitates the multiplexing.
Access PanelThe Cisco 3-tier-network representation’s lowest level, the access-panel, ensures that packets reach the end-user devices. Access Panel is often referred to by the term desktop layer as it focuses primarily on connecting client computers to the network. Access Panels include hubs, switches, multi-stations and access units.
Core Network DesignCore Network Design, Aggregation, Access Layers and the Data Center Architecture are layers. These layers have been defined concisely and broadly throughout the paper.
The Core Layer — This layer provides the packet-switching-back-plane to all transmissions throughout the data centre. The core layer connects a series combination elements to deliver a durable Layer three-directed material without any point of failure. This core-layer supports interior routing protocols (such as EIGRP, OSPF) and loads-balances traffic across the site and aggregation core layers using Cisco Express forwarding-hashing algorithms. *
The Aggregation Layer modules — This is the layer that runs important tasks, such as service module incorporation. It also handles spanning trees, repeating default gateways, and Layer 2 definitions. The aggregation layer is used to transmit multi-tier server-to-server traffic. It can use services such as firewalls and server load-balancing to protect and improve the system.
This layer is where the servers physically connect to the network. These server systems include blades servers connected to fundamental switches, 1RU, blades servers connected via pass-through cabling and mainframes. The access layer of a telecommunications network is comprised of sectional switches. Switches can be configured in Layer 3 or Layer 2 to satisfy the needs of different broadcast domains and administrators. Network RequirementsWe want to offer ecommerce to our clients to allow them to get our services in a more convenient way. For this reason, we require a very safe network due to the high level of protection our product has. This technique will also allow us to allocate different budgets on our employees and to offer different bonuses. We will create our own protocols for security. We will be using our own servers for all security measures. As soon as this network is set up, digital certificates are required. SSL enhancements and vulnerability scanning must also be considered.
First, we’ll check DNS servers. This is what converts domain names to IP addresses. Many options are available, but we will use our own native DNS server to secure our net. Century Link will serve as our ISP. Their DNS will be used for the unclassified web. On an internet application server, we will have DHCP services running. OSPF/BGP/static routes will be used to run the network protocols. (Bishop), We will assign non-public addresses to host machines which go through a network address translation once they leave the network. We’ll have a regional CA authority to handle any client services. All active hosts may have native CA authorization. The certs must be updated frequently. Users can also use two-issue authentication. Cyber team may handle this. The client support will be provided by a combination of technical and sales groups. The groups will also monitor the system to prevent any issues from occurring, as well as push updates. All support will be provided in-house for security. We can select and build the items once a budget approval has been granted. For security, we’ll be using servers in-house. The Cisco 7030 is a good example of an external firewall, demilitarized zones, active and passive Intrusion Detection System (IDS), and zone. A firewall with an ACL, Access management List (also known as Access management List), must be set up to prevent certain traffic from ports. Splunk software can be used to program the department. It will monitor traffic actively and send alerts to state personnel in the US. It will also monitor cyber-attacks. The HBSS will cover all firewalls and antivirus. The Network will have to be connected to the internet. In addition to being compliant, it had to be auditable, and comply with American state, data Assurance or Data Assurance compliance, for reasons of legal and safety. DISA (Defense Data System Agency) on category compliance is required for all traffic that crosses the system. This will ensure the network’s proprietary compliance. OSPF is used with BGP for dynamic routing. The benefits of OSPF are that it is open source and can be used by all devices. It automatically detects Next Hop equipment. OSPF has a downside when their list of networks becomes large. This can cause a slowdown because OSPF is trying to keep it up to date. BGP, also known as (OSPF), can be utilized on the server’s backplane. Its biggest benefit is the ability to create as big a list of networks as possible. OSPF could be used to create a very native-like network. BGP, on the other hand, would be used to route WAN traffic and connect nodes.
You can tell it where you want to go. Tell it where you want it to go. This gives you consistency. It makes it very difficult to keep up with the changes. Once you have a few devices, it’s easy to manage. However, as soon as you add more devices, the process becomes difficult. You can’t perform Quality of Service checks because it will create a bottleneck. OSPF will automatically be used in conjunction with Static. Cisco routers will be used for science routing. All cisco instruments will be used to keep everything uniform and make sure that it is compatible. Routing tables are used by routers to determine the next hop address where a packet should be sent. Routers maintain routing tables and store them in RAM. This is usually done to confirm the path to a network destination. Microsoft lets you revoke or issue digital certificate. These are commonly used to modify SSL Sessions and to demonstrate your identity as a computer, extranet or website. Certificate Services can be run on any certificate server. These servers may be organized according to 4 different certification authorities. The Enterprise Root CA is the server in the Windows domain’s hierarchy.
Internet InfrastructureThe Internet is a global network of computers with unique network addresses. The telecommunication network’s pcs connect to the Internet through an online service supplier. After a computer is connected directly to the internet through an online provider, it receives a short-lived web Protocol. A permanent net protocol is still connected to the internet through the area space network. The TCP/IP stack includes:Applications Protocol Layer: this allows computers to access the globe Wide net, emails and therefore the File Transfer Protocols. Transmission control protocol (TCP Layer): This forwards frames towards the Media Access address (MAC Address) using a particular port on a computer. IP Layer – This layer is used to direct packets at a certain pc using its science address. Hardware Layer : frames are reborn as network signals from binary. They are local area networking cables, Wi-Fi, and modems.
Access Networks DesignTechnologyTo connect dedicated internet line, the network must have the following infrastructure.
Backup server: If the internet is down, it’s important to have a server that can store data. This backup computer should be strategically plugged into the switch so it can be accessed by any or all of the computers licensed within the network.
Firewall: it is important to enable the firewall in the software that connects devices to the web to protect them from malicious intrusion. To ensure the security of web access, it is also necessary to install antivirus, antispyware or antimalware.
Operating System: Laptop devices need operating systems that allow dial-up sessions. Users will also need a browser system such as net soul to access the internet.
Ethernet: Computers are required to be linked to the backup server and router through a local area network. This connection is made through LAN cable.
Switch: The switch is an intelligent networked device that can communicate efficiently with other devices. Switches save money and increase productivity for businesses by sharing data and allocating resources.
Justification of technologyThe proposed telecommunications system is a Wide Area Network. For it to function properly, both cable and wireless computer networks are required. Some of the resources that are used to build this network in order to serve the demographics effectively and fully include:
Cloud Computing: Cloud-based computing allows for a large number users to backup their information. These users are also able to share resources on-the-go. It allows for quicker information sharing and access.
Firewalls are designed to block intrusions using a variety methods. Firewalls are used to mask IP addresses and prevent intrusion. Firewalls allow external computers to communicate with each other before they reach the computer intended for a particular network. Firewalls only allow connections from verified, reliable networks. Additionally, firewalls with packet-filtering evaluate every packet and reject all that do NOT meet the requirements for security.
Wireless modems are essential because the telecommunications system is deployed over a vast area. Wireless networks are easily accessible by mobile users. Wireless networks can also be used where fiber-optic cables cannot be installed.
Implementation of NetworksThe implementation phase of a planned telecommunications project can be one of the most crucial parts of the whole project. For a triple crown implementation, there are some major tasks that must be completed in the implementation phase. These major tasks are also necessary to ensure that the electronic network is accepted by users. Following are a few of the major tasks that must be accomplished during the implementation phase.
* The coordination and organization of implementation.
* Training for users.
* Documentation on the proposed telecommunications network.
* Create an expert team to support the network.
* Implementation of the electronic network requires a special process.
* Conduct a survey of the network website before implementation.
* Purchase hardware and computer codes for implementation.
* Convert the needed information to a form that can be read by the network.
* Prepare the positioning of the network for its implementation.
Use the following to calculate the amount of resources needed for the final phase:
* Hardware – LAN cables, routers and computers are all needed to implement the system.
* Software. The package is needed to implement the planned telecommunications system. It includes Antivirus, Malware protection, Network Automation package and Network Monitoring package.
* Data needs – these are the datasets that will be needed to implement the project. Personnel IDs, for example, may be required to create personnel authentication accounts. These accounts would be used to modify the licensed personnel’s access to the planned electronic telecommunications network.
* Physical facilities – A site should be set aside for the development of an electronic network.
Some of these risks include:
* Network Specifications are broken down – during implementation, certain network requirements may conflict. Network engineers may notice that some network specifications are unclear or incomplete. A complete network analysis could be done at the beginning stages to solve this problem.
* Underestimation risks – This is a result of underestimating the budget or timeline. To ensure that the network is programmed and estimated correctly, engineers need to keep track of previous events.
The lack of proper implementation can lead to procedural risks. The problem could be resolved with a clear division of responsibility within the part that implements.
* Technical risks: To keep within the allocated budget, the management may choose to purchase a less expensive package. This could cause the computer network to lose its practicality.
* Uncontrollable dangers – These are risks that cannot be controlled by network engineers. They include risks associated with government policies or package periods of time.
Network analysisThe method of project analysis begins at the development stage and is then divided into validation, human factor assessment, and clinical evaluation. Verification evaluates the product development according to its specific functionalities. It ensures that the product is complete, consistent and accurate. Validation confirms that the product performs as designed in the $64000 operating environment. Human factors analysis is a crucial part of the system analysis.
When users are unable to adopt the new network, they will resist. It is therefore important to include coaching as part of network development. Users are usually reluctant to learn about new technologies.
Training CriteriaTo prepare the users for IT training, the system provider must introduce coaching material, implement a coaching protocol, and guide the right program. The network division must be obliged to support the supplier and ensure the training sessions cover all aspects.
