WI-FI SOLUTIONS & SECURITY

WI-FI SOLUTIONS & SECURITY:


We provide wi-fi solutions for homes offices hotels and hospitals to provide wireless access around site. We assure fully feasible wireless coverage to access network around site

We provide wi-fi environments such as:


  • • Educational institutes: Educational facilities are under tremendous demand to provide fast, reliable WiFi for students and faculty alike. With limited dedicated personnel and budgets and where many have multiple devices that require robust connectivity, we have the simple, affordable, and proven wireless solutions that make connected learning easier and available for all.

  • • Hotels & offices : Guest and employee satisfaction and are a top priority for you, and part of creating that loyalty includes delivering a strong, consistent WiFi experience. For many hotels & offices, existing WiFi solutions are having a negative impact on guest and employee satisfaction. The right wireless infrastructure can solve that problem. NR networks features a complete wireless solution designed for hotels and offices

  • • Hospitals: Electronic health records, immediate access to health information, and continuous connectivity across the facility are key to delivering superior patient care.Therefore, the ability to connect a wide range of devices; maintain wireless connectivity across the facility; store, protect, and share sensitive patient data; and maintain reliable, high performance are essential. NR networks delivers complete networking solutions for hospitals.

ABOUT WIFI SECURITY :


A consideration on any computer network, security is especially important on Wi-Fiwireless networks. Hackers can easily intercept wireless network traffic over open air connections and extract information like passwords and credit card numbers. Several Wi-Fi network security technologies have been developed to combat hackers, of course, although some of these technologies can be defeated relatively easily.

Network Data Encryption :


Network security protocols usually use encryption technology. Encryption scrambles data sent over network connections to hide information from humans while still allowing computers to properly decipher the messages. Many forms of encryption technology exist in the industry.

Network Authentication :


Authentication technology for computer networks verifies the identity of devices and people. Network operating systems like Microsoft Windows and Apple OS-X include built-in authentication support based on user names and passwords. Home network routers also authenticate administrators by requiring them to enter separate login credentials.

Ad Hoc Wi-Fi Network Security :


Traditional Wi-Fi network connections go through a router or other wireless access point. Alternatively, Wi-Fi supports a mode called ad hoc wireless that allows devices to connect directly to each other in a peer to peer fashion.

Lacking a central connection point, the security of ad hoc Wi-Fi connections tends to be low. Some experts discourage the use of ad-hoc Wi-Fi networking for this reason.

Common Wi-Fi Security Standards :


Most Wi-Fi devices including computers, routers, and phones support several security standards. The available security types and even their names vary depending on a device's capabilities.

WEP stands for Wired Equivalent Privacy. It is the original wireless security standard for Wi-Fi and is still commonly used on home computer networks. Some devices support multiple versions of WEP security

  • • WEP-64-bit key (sometimes called WEP-40)
  • • WEP 128-bit key (sometimes called WEP-104)
  • • WEP 256-bit key

and allow an administrator to choose one, while other devices only support a single WEP option. WEP should not be used except as a last resort, as it provides very limited security protection.

WPA stands for Wi-Fi Protected Access. This standard was developed to replace WEP. Wi-Fi devices typically support multiple variations of WPA technology. Traditional WPA, also known as WPA-Personal and sometimes also called WPA-PSK (for pre-shared key), is designed for home networking while another version, WPA-Enterprise, is designed for corporate networks. WPA2 is an improved version of Wi-Fi Protected Access supported by all newer Wi-Fi equipment. Like WPA, WPA2 also exists in Personal/PSK and Enterprise forms.

802.1X provides network authentication to both Wi-Fi and other types of networks. It tends to be used by larger businesses as this technology requires additional expertise to set up and maintain.

802.1X works with both Wi-Fi and other types of networks. In a Wi-Fi configuration, administrators normally configure 802.1X authentication to work together with WPA/WPA2-Enterprise encryption. 802.1X is also known as RADIUS.

Network Security Keys and Passphrases :


WEP and WPA/WPA2 utilize wireless encryption keys, long sequences of hexadecimal numbers. Matching key values must be entered into a Wi-Fi router (or access point) and all client devices wanting to join that network. In network security, the term passphrase can refer to a simplified form of an encryption key that only uses alphanumeric characters instead of hexadecimal values.

However, the terms passphrase and key are often used interchangeably.

Configuring Wi-Fi Security on Home Networks :


All devices on a given Wi-Fi network must use matching security settings. On Windows 7 PCs, the following values must be entered on the Security tab of Wireless Network Properties for a given network:

  • • Security type refers to authentication options including Open, Shared, WPA-Personal and –Enterprise, WPA2-Personal and –Enterprise, and 802.1X. The Open option utilizes no authentication, while Shared utilizes WEP for authentication.
  • • Encryption type options available depend on the Security type chosen. Besides None, which can be only used with Open networks, the WEP option can be used with either WEP or 802.1X authentication. Two other options, called TKIP and AES, refer to specialized encryption technologies usable with the WPA family of Wi-Fi security standards.
  • • An encryption key or passphrase can be specified in the Network security keyfield when required.
  • • The Key Index, a value between 1 and 4, refers to the position of the matching key stored on the wireless router (access point). Many home routers allow four different encryption keys numbered 1 through 4 to be configured in order to support legitimate clients without forcing them to all use a common key.
