What is WiFi ?

WiFi, the short for “wireless fidelity,” is the name of a popular wireless networking technology for wireless local area networking with devices based on the IEEE 802.11 standards. It uses radio waves to provide wireless high-speed Internet and network connections.

What is LiFi ?

LiFi, the short for “light fidelity”, is a wireless optical networking technology for wireless communication between devices using light to transmit data. In its present state only LED lamps can be used for the transmission of visible light. It is a safer, greener and cheaper technology as it does not have any radio waves or any other type of waves.

Following poster mentions feature comparison between WiFi and LiFi technology.

To conclude

After carefully examining the above two technologies, it is quite evident that the new LiFi technology is not the replacement of WiFi technology. Both WiFi and LiFi has its own advantages and limitations. Although LiFi seems to be temptingly faster many people believe that LiFi will just remain as an alternative to WiFi and might not replace it completely.

Blockchain is a term that everybody is hearing about nowadays. It is undeniably a cunning invention. Defined in simple terms, blockchain is an original method to identify who owns what through technology. In this short post, we will tell how blockchain and cyber security relate.

“The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value.” Don & Alex Tapscott, authors Blockchain Revolution (2016)

Through this technology, one can keep track of transactions and is able to connect a million of computers across the globe. This is accomplished through adding those machines to a public accessible “ledger”, that until now can not be hacked or corrupted.

Let’s imagine it a database available, and continuously being updated across a network. Every transaction occurring over this database is known as a “block”.

Prohibiting individuals from controlling the data available, would limit chances of failure. Some of the main advantages of using blockchain are transparency, and decentralization.

Blockchain to Enhance Security

So how would blockchain and cyber security relate? We all rely on our web identifications and passwords, and are very cautious of any information thefts. Ensuring a secure identity is very crucial for any online interaction.

With Blockchain, security is enhanced through the encryption technology.

Technically speaking, blockchain uses a public key (users address), a private key (like passwords), and a paperwallet that allows individuals to protect their keys.

Blockchain technology is an innovation in cyber security, however the complications of the technology are to be taken into consideration and may hinder development in its application.

Why CIATEC?

CIA TEC name was inspired by two main fields of interest, information security field represented by CIA triad (Confidentially, Integrity and Availability) and information technology being the wide umbrella covering several topics underneath it, with emphasis on IT Service Management (ITSM), IT Security and Digital Strategy.

Work in Progress

CIATEC is still a new born that is being nourished by an ambitious small team of beautiful minds with solid background in digital and information technology, systems management, network management, information security, IT security and IT operations management.

We believe that there is always a room for improvement. We invite you to share with us any suggestions or comments about CIATEC here or through our social media channels:
