Website Testing: The Elements Involved





Website testing is carried out to assure the web page quality and functioning. It includes so many testing areas and various testing activities to check a website from different angle and perspective.



The ultimate aim of the website testing is to make a website more comfortable to use and easier to navigate. Users can understand the message more clearly with a quality tested website. 





Website Testing includes the following Testing Procedures:


Usability Testing 

To ensure how much a website is user-friendly. An easy to navigate and clear user interface is the key component in order to engage the visitors on the pages. 


Functionality Testing

To check whether the website is working well with its aimed functionalities and features. 

Some of the elements in the Functionality Testing:
Forms Testing with all its fields
Link Testing
Validation Testing
Cookie Testing
Database Testing



Testing for Compatibility

This is to test the compatibility of a website on multiple browsers, operating systems, networks, hardware, software, and many other devices. 



Site Performance Testing

To check the smooth working of a website under expected, unexpected conditions, and environment. Here, the site is checked for the stability under different load conditions (if plenty of users visit the site) and thus the response time, and the speed of the website under different load and conditions are calculated. 



Security Testing

This is a very important test, because if the site is not secure, it will exist NO MORE. The site should be checked thoroughly for any loop holes or security breach through which malicious users or hackers can attack and destroy the site. 

Following Activities Include in the Security Testing:
Penetration testing to detect security loopholes.
Accessing website using incorrect password multiple times.
Checking server log files
Hacking the login details and cracking the password.

Data Security and the Protection Measures


Data Security can be defined as the protection of data from unauthorized access and data theft in its entire life cycle. It means securing the data from unofficial modification or destruction by using physical security means, administrative level controls, logical controls, and other ways of safeguards to restrict accessibility.




The Ways of Securing Data Include:

  • Data Encryption: The data will be converted into a code which required a key to unlock it.
  • Masking of Data: The data will be masked and needs authorization to open it. 
  • Data Backup: Making continuous backup of the data, so the data can be recovered if the master copy is lost. 
  • Erasure of Data: This technique is to ensure that the erased data is completely removed and unauthorized people can’t recover it.
  • Cloud Security: Moving the data to cloud securely in order to protect data. 


Why Data Security?

Data Security has got high concern and companies are spending heavily for data security management. A business –even though it is well established- needs and also depends on a vast pool of reliable data to run its business. Upon losing their valuable data, or altering the data by some intruders can cause an enterprise to fail forever.


Data Protection Measures for Enterprises

Implement multiple layers of security. 
Apply logical security like authorization, authentication, encryption and passwords.
Apply physical security like restricted access and locks on server, storage and networking cabinets. 


Type of Data Security Devices


Firewalls
















Antivirus Scanning devices


















Content Filtering devices

















Intrusion Detection devices 















Preventative devices






















Unified Threat Management (UTM) devices

The Human Like Robots

  
It was considered impossible to create a machine (robot) with feelings and emotions, but it is going to be NOT SO FAR that people can see everywhere robots with human like behavior, feelings and emotions. It has become possible to develop a computer program that can process this type of (emotions) data to create a real humanoid Robot which can have emotions and feelings and can interact with people naturally.

The developers of this robotic emotions code say that programming languages like C, C++, C#, Java, VB.net, Python can be used for this.

Recently, a Japanese telecom company has released a robot ‘Pepper’ which has emotions and feelings. It is considered as the “the first human like robot designed to live and behave with humans.


They say that the Pepper can feel joy, surprise, anger, doubt and sadness.

SDN - Software Defined Networking




Software Defined Networking (SDN) is an approach to using open protocols to execute globally aware software control at the end of the network to access network switches and routers that typically do use closed firmware.

SDN enables the network to be intelligently controlled using software applications. This helps network operators manage the entire network consistently, without bothering the underlying network technology.


Software Defined Networking: The Benefits



SDN has so many benefits to offer like automated load balancing, on-demand provisioning, streamlined physical infrastructure and the capability to scale network resources in lockstep with application and data needs. 


SDN: The Evolution of the Networks

SDN helps the programming of network behavior in a centrally controlled manner through software applications by using APIs. By implementing a common SDN control layer, the network operators can manage the entire network and its devices consistently, regardless of the complexity of the underlying network technology.


The Critical Areas where SDN technology can make a difference:

  1. Network programmability feature: SDN helps network behavior to be controlled and maintained by the software which resides beyond the networking devices.  Hence, network operators can easily tailor the behavior of their networks to accommodate new services. 
  2. Logically centralized intelligence and network control: SDN enables intelligent control and smart management of network resources. With centralized control, bandwidth management, data restoration, network security, and policies can be highly intelligent and well optimized.

The Role of Routers in a Network



What is a Router?

A Network Router is defined as an electronic device that connects multiple networks by sending data packets. Normally, a data packet is forwarded from one router to another router via networks until it reaches its destination node. 
The most common types of Routers are home and small office Routers that simply forward IP packets between home/office computers and the internet.


Functions of a Router

The main function of a Router is to forward the packets based upon a routing table. They also offer traffic segmentation, multiple broadcast domains and define network layer addressing subnets and networks. IP address are assigned to those networks which are defined by Router Network Adapters or Ports. These assigned IP addresses are considered as the default gateway to PCs, computer servers, or other networking devices.

In simple words, Routers communicate with each other to share information about the available paths to send data packets. 






Difference Between A Switch and Router

Actually, Routers and Switches are computer networking devices which allow one or more PCS to connect to other PCs, networked devices, or to other networks.

A switch connects multiple computers together in a LAN. After the first data transfer, it creates a “switch table” which matches the ports to connected devices by their MAC addresses.

A Switch can connect several devices in a LAN, and it can differentiate the computers as the data passes through it. Switches can recognize which port is connected to the device.

In a Router, IP address is stored in a routing table. The Routers Connect two or more networks, but at the same time, a Switch connects two or more nodes in the same network or different networks.






Types of Routers


Wired Router

They are box-shaped devices that connect directly to computers through wired connections. 

One connection port on a wired Router equips it to connect to a modem for receiving Internet data packs, while other set of ports allow it to connect to computers 


Virtual Router

A Virtual Router acts as a default Router for computers sharing a network. This Router works using the VRRP (Virtual Router Redundancy Protocol), which becomes active when a primary physical router fails.


Core Router

A Core Router is a wired or wireless router which distributes Internet data packets within a network, but same time, doesn’t distribute data packets between multiple networks. 


Wireless Router

A Wireless Router forms a wireless local area network (WLAN). The most common standard for WLAN is Wi-Fi. To protect Wi-Fi networks, wireless routers normally employ wireless media access control (MAC) address filtering, and Wi-Fi Protected Access (WPA) security.


Some of the Best Routers Available in the Market, Currently:

  • Cisco Linksys E900 Wireless N300 Router
  • Netgear WNR614 N300 Wi­Fi Router
  • TP-Link TL-WR740N 150Mbps Wireless N Router
  • Netgear WGR614 Wireless-N 150 Router
  • D-Link DSL-2750U Wireless N ADSL2+ 4-Port Wi-Fi 
  • Asus N600 RT N56U Dual-Band Wireless Gigabit Router
  • Apple AirPort Extreme Wireless Router

Advantages of Routers:

  • It can function on both LAN & WAN
  • Router can determine the best path for data 
  • It can connect different media & architectures.
  • Router can easily filter the broadcasts.

Disadvantages of Routers- 

  • Router works only with Routable Protocol.
  • Router is more costly than Hub, Bridge & Switch. 
  • Routing updates will consume bandwidth.
