Data communication cannot be separated from Networking Equipment and supporting devices that accompany it in a data communication process.
Networking has been very developed, so it has entered into various aspects of life and greatly facilitates life both in the Home, Office, Government and other Activities.
The right choice of Products and Services from Networking will help smooth the work process related to data communication.
Since the Covid-19 Pandemic, Networking has grown tremendously to help smooth work, especially in conditions of Working from Home or working remotely.
SMI has experience in building reliable Networking for SOHO, Enterprise and Public.
SOHO network or also termed as single or small office/home office network is mainly referred to a business category involving a small number of workers usually from 1 to 10. It is a type of local area or LAN network connection meant to be used in small businesses.
Like many other LANS, SOHO network may also be a mixture of networks of wireless or wired computers. The SOHO router is more or less the conventional broadband router designed to be operated in such organizations.
A SOHO network may also support a bit larger group of peoples and is generally a privately owned or owned by self employed individuals for a smaller business organization.
SOHO, nowadays, is becoming more and more popular in different sectors including networking circles. As there is increase in the number of smaller business units, the call for SOHO networks is also in demand and is on the rise day by day.
The features and benefits provided by SOHO such as easy to use and setup network etc. makes them an ideal choice for the same. Virtual office is another synonym sometimes used for a SOHO network. SOHO networking is mainly used for the purpose of connecting several computing devices on a single network to share the information effectively with the connected multiple users in the organization.
Each and every connection for a SOHO network needs some of the common connecting devices. Below are mentioned some of the top requirements for setting up a SOHO network:
Router tops the list of the most basic and important requirements for a SOHO network access. They are also the best choice to be used in small offices because of their ability of identifying IP address through each of the computing devices. Some of the good routers will also include an inbuilt option of a firewall system which also helps in preventing malicious attacks which generally comes from the files or data coming from the web.
All the computing devices on the SOHO network will also require a network card along with a network adapter or a network cable. This will be helping you in the process of file sharing when single computer on network known as server will be accessing the network and sharing the files with the shared computer on that network.
Modem is also an essential need for this network as it will be mainly responsible for receiving and communicating the signal from the service provider of the internet.
Every SOHO communication makes use of a large number of apparatus to ensure that the signal is free flowing and the information is transmitted without any loss in the system.
Network cable is also required for this purpose.
The network cable will serve as a medium and set up the link between the modem and the router. Ensure to connect the cable in the appropriate port of each side. Now, begin with SOHO by connecting the computer to the routers and the modem with internet cable.
Device types or requirements
There are many other types of requirements which are a necessity for creating a SOHO network. Few of them can be listed as:
Hardware requirements: These consist of an Ethernet adapter for every computer that you will be connecting on the network. While buying any new equipment, use 100 base T equipments. If you already possess 10 base T adapter cards, buy dual speed 10/100 hub which will help you in maintaining backward compatibility along with the previous equipment and forward compatibility with newer equipment.
Ethernet Hub: The working of a brand is good as the range over which the hub goes. Get the one which has more ports than the number of devices you wish to add to the network. The other thing to be kept in mind while buying is if the hub is 10 base T or 100 base T or both. If you are planning to use older equipment, then it is advised to go for a dual speed hub and if not, then get yourself a 100 base T hub.
Adapter cards: For each of the computer you wish to add to the network, you will need an adapter card. While buying the cards, you will need to make it sure that they will be compatible with operating system and the hardware of the device on which it may be installed. PCI adapters of NE2000 clones are best suited and easy to use on a LINUX operating system. Any of the adapter cards you intend to buy, just make sure they are faster 100 base T cards. You will need to have the knowledge of operating the computer and installing the adapter card for this purpose.
Wireless Network Interface Card (NIC): For each of the computer you wish to add to the network, you will need a wireless network interface card. It is an Ethernet card which also has a built in antenna which helps in communication of the device with the access point.
Wireless Access Point: This will act as central receiver for the device. This wireless access point will be connected to the wired switch or network router.
The SOHO network should be carefully planned keeping the environmental limitations and considerations in mind. There is a range of environmental considerations to be kept in mind before designing a SOHO network especially if you are looking to design a wired network.
Make sure that the routers or any network switches are in a proper area which is confined from flooding dangers and the high humidity factors or not cold enough so that a proper operating temperature is maintained. In case of a wireless network, structure and design of the building should be taken into account and things responsible for reflection or absorption of the radio waves must be taken care of. You won't need any expensive designing but it will be mandatory that you can see the data yourself and nobody else can.
There are also a set of unique and different set of requirements required for a SOHO network. The infrastructure challenge is a big one which can be different from many of the corporate offices Plan a proper outlay of supporting the different devices for longevity. Also, equipments will require a moderately cooler temperature so that they do not get heated up quickly and can function properly for longer use. A ventilated area will serve the purpose.
An Uninterrupted Power Supply (UPS) is also a necessity for setting up the SOHO networks in case of any power failure or power outage so the servers can continue to work normally. Be aware of the wireless network around the building to avoid conflicts between them and make a proper control over it. Don't mix or set up the network at the same frequency as the person next door is using to avoid conflicts.
Most of the devices purchased and used in a SOHO network are basically a scale down version of the exact equipment that is used for the enterprise network. For instance, a router can also add security configuration and specific static routes, but it most probably be in graphical user interface system so that one can easily understand the process without any training requirement. There will also not be available the redundancy and flexibility that you will be getting in an enterprise networking system. Thus, this should probably not be suitable for use in larger networks.
SOHO equipment should only be used in a SOHO environment and not meant to be used at larger networks. You need to know that the equipments are less capable and are a smaller version of the big ones. Network, power and environmental conditions are all different for these types of equipments. Also, this will be costing you some lesser bucks because of the lesser features and can help in financial trade off. The device is designed to meet the needs of fewer people, so it will have lesser speed and also contains redundancy limitations. These also do not have a lot of management options available to them, there are not a lot of command line and not a lot of diagnostics that you can perform in an enterprise network. There are also not a lot of options available for upgradability, this means that it will be limited by the amount of internet bandwidth that will be coming to your home or the building.
The most important process for setting up a SOHO network is to know about the compatibility requirements. The hardware requirements, software requirements, adapter cards etc. and all the basic equipments required have to work in collaboration to build up a good working SOHO network. This will make it easier to troubleshoot and make up for a stronger network.
Every site for the SOHO network will be configured identically to make the network as a standardized unit. Make sure the network pieces can all talk between them properly even if it is a wired connection or a wireless one. The wireless access points may not function or communicate the same way all the other wireless technologies does. So, the enterprise will be providing that standard set of SOHO for both the wired and wireless infrastructure.
TCP/IP protocol is generally used these days to communicate the wireless technologies and in a SOHO configuration setting, the TCP/IP may also be standardized from site to site. An interesting compatibility requirement between the various operating systems like Windows, MAC OS or LINUX etc. need to be made sure that they are built in a SOHO. Backup requirements in a SOHO may also be a little bit different.
SOHO businesses are exaggerating with the advancement in technology which allows the workers from home to attach to internet whenever and wherever they want. With the services and goods being made especially for these smaller networks, the SOHO network and its demand is on the rise and you just need to make sure of the whole system working together. Get ready to even open you small office at maybe from your home with these little yet big SOHO networks..
"Enterprise network" denotes the IT infrastructure that midsize and large organizations use to provide connectivity among users, devices, and applications. The goal is to support the organizations' objectives by consistently delivering connected digital services reliably and securely to workers, partners, customers, and, increasingly, also things.
A well-designed enterprise network provides the proper connectivity for all users, things, devices, and applications present in an organization, as appropriate for the role, purpose, and location of each
Campus, branch, and Internet of Things (IoT): These networks provide fixed and mobile access to users and things. They are present in all areas of an organization, both in offices and in operational spaces such as manufacturing and warehouse facilities. These networks are optimized for transparent, secure access and high density.
Data center and hybrid clouds: These networks connect to and among applications, workloads, and data, within on-premises data centers and private and public cloud services. They're optimized for low latency, security, and mission-critical reliability.
Wide-area networks (WANs): These networks connect facilities, buildings, or campuses to other branches, to data centers, or to cloud resources. They're optimized for user experience and bandwidth efficiency.
Wi-Fi 6, 5G, and newly opened frequency bands for ultra-fast, short-range transmissions are enabling access to high-speed wireless connectivity for more users and IoT devices in more settings. At the same time, 400 Gbps is the new standard for high-speed data center networks. These innovations are spurring productivity enhancements and continued innovation across organizations.
Automated and intelligent networks
Increasingly, network management is being automated, with software that can recognize connected devices, profile them, and determine whether they can be trusted. They can detect performance problems or potential threats and respond automatically. Artificial intelligence (AI), machine learning (ML), and machine reasoning (MR) are now making networks smarter by adapting to the unique needs of each organization and customizing recommendations.
More and more enterprises are aligning their networks to intent-based networking (IBN) principles. Intent-based networks use advanced analytics along with software-defined networking (SDN)-based automation to continuously align network performance to changing business needs. They capture business intent, translate it into policies that can be applied consistently across the network, and continuously monitor and adjust network performance to help achieve desired business outcomes.
Widespread mobility and cloud adoption require an enhanced approach to protecting users, applications, and data. A zero-trust security framework helps to prevent unauthorized access, contain breaches, and reduce the risk of an attacker's lateral movement through the network
A well-designed enterprise network provides the proper connectivity for all users, things, devices, and applications present in an organization, as appropriate for the role, purpose, and location of each.
Optimized user experience
An enterprise network can help improve the user experience through proactive network optimization, faster issue resolution, proper prioritization of essential traffic, and helping to ensure security and privacy.
Readiness for digital transformation
An enterprise network can be designed to support digital initiatives needed to quickly adapt to rapidly evolving needs, including expansion, scaling, growth, and introduction of new services.
Easier network management
Network management tools such as network controllers give administrators the ability to set access rules and permissions for users and departments, add new users or functions easily, and monitor performance and take corrective action, all from a central interface.
In addition to security applications and devices, such as firewalls and secure Internet gateways, an enterprise network becomes a primary detector of threats and an enforcer of security and compliance. It does so with device identification, profiling, and verification, network monitoring, authentication, access controls, segmentation, and device and account management.
Flexible software subscriptions
Enterprise networks that use subscription-based licensing get continuous access to the latest networking and security innovations. They are better able to keep pace with their expanding demands as technologies and requirements change.
Seamless cloud integration
As more and more data and applications are developed, deployed, and delivered across multiple public clouds, enterprise networks provide seamless connectivity between users and cloud applications. They also optimize workloads between on-premises locations and public clouds.
Network security combines multiple layers of defenses at the edge and in the network. Each network security layer implements policies and controls. Authorized users gain access to network resources, but malicious actors are blocked from carrying out exploits and threats.
protects your network and data from breaches, intrusions and other threats. ... Network Security involves access control, virus and antivirus software, application security, network analytics, types of network-related security (endpoint, web, wireless), firewalls, VPN encryption and more..
Firewalls put up a barrier between your trusted internal network and untrusted outside networks, such as the Internet. They use a set of defined rules to allow or block traffic. A firewall can be hardware, software, or both. unified threat management (UTM) devices and threat-focused next-generation firewalls..
Email gateways are the number one threat vector for a security breach. Attackers use personal information and social engineering tactics to build sophisticated phishing campaigns to deceive recipients and send them to sites serving up malware. An email security application blocks incoming attacks and controls outbound messages to prevent the loss of sensitive data.
Anti-virus and anti-malware software
"Malware," short for "malicious software," includes viruses, worms, Trojans, ransomware, and spyware. Sometimes malware will infect a network but lie dormant for days or even weeks. The best antimalware programs not only scan for malware upon entry, but also continuously track files afterward to find anomalies, remove malware, and fix damage..
Software-defined segmentation puts network traffic into different classifications and makes enforcing security policies easier. Ideally, the classifications are based on endpoint identity, not mere IP addresses. You can assign access rights based on role, location, and more so that the right level of access is given to the right people and suspicious devices are contained and remediated...
Not every user should have access to your network. To keep out potential attackers, you need to recognize each user and each device. Then you can enforce your security policies. You can block noncompliant endpoint devices or give them only limited access. This process is network access control (NAC)...
Any software you use to run your business needs to be protected, whether your IT staff builds it or whether you buy it. Unfortunately, any application may contain holes, or vulnerabilities, that attackers can use to infiltrate your network. Application security encompasses the hardware, software, and processes you use to close those holes...
To detect abnormal network behavior, you must know what normal behavior looks like. Behavioral analytics tools automatically discern activities that deviate from the norm. Your security team can then better identify indicators of compromise that pose a potential problem and quickly remediate threats.
Data loss prevention
Organizations must make sure that their staff does not send sensitive information outside the network. Data loss prevention, or DLP, technologies can stop people from uploading, forwarding, or even printing critical information in an unsafe manner.
Data Loss Prevention..
Intrusion prevention systems
An intrusion prevention system (IPS) scans network traffic to actively block attacks. IPS (NGIPS) appliances do this by correlating huge amounts of global threat intelligence to not only block malicious activity but also track the progression of suspect files and malware across the network to prevent the spread of outbreaks and reinfection....
Mobile device security
Cybercriminals are increasingly targeting mobile devices and apps. Within the next 3 years, 90 percent of IT organizations may support corporate applications on personal mobile devices. Of course, you need to control which devices can access your network. You will also need to configure their connections to keep network traffic private....
A virtual private network encrypts the connection from an endpoint to a network, often over the Internet. Typically, a remote-access VPN uses IPsec or Secure Sockets Layer to authenticate the communication between device and network...
A web security solution will control your staff’s web use, block web-based threats, and deny access to malicious websites. It will protect your web gateway on site or in the cloud. "Web security" also refers to the steps you take to protect your own website.
Wireless networks are not as secure as wired ones. Without stringent security measures, installing a wireless LAN can be like putting Ethernet ports everywhere, including the parking lot. To prevent an exploit from taking hold, you need products specifically designed to protect a wireless network.k...
The main difference between server and storage is that the server is a hardware device or a program that provides services to the client machines in the network according to their requests while the storage is a component in the computing device that stores data for long-term accessing. A server provides various services to multiple clients. They store and manage data, allows sharing resources, perform computation and many more. There are powerful servers running in data centres for efficient and reliable communication. However, storage refers to secondary memory that stores data permanently. It allows the processor or the CPU to transfer its data to the memory (RAM) for short-term data access.
Server technology has come a long way in the last 10 years. Why 10 years? No real reason, really. I chose that figure pretty much arbitrarily. Because whether you pick 20 years or two years, as with all things in technology — and in life — change is the only constant. Just consider the fact that what we in IT call servers today are vastly different from what we called them just 10 years ago. In fact, a “server” today isn’t even necessarily an actual physical device. With this in mind, let’s take a look at six of the biggest trends now operative in server technology.
A thin client is a computer that runs from resources stored on a central server instead of a localized hard drive. Thin clients work by connecting remotely to a server-based computing environment where most applications, sensitive data, and memory, are stored.
