Fundamentals of information security

Technology has covered almost all facets of today ' s world.
From dusk to dawn, we are engaged digitally.

From smartphones at home to meet all our daily needs, to make a fund
transfer,

to ordering a refill of groceries, everything is just a click away.

A typical day at the workplace involves dealing with connecting to intranet/internet servers.
A relaxed weekend at dine-in will involve the attendees taking customer's orders through a tablet.
The customer paying the bill through a Credit/Debit card.
All these transactions involve accessing the internet.
Hence it becomes important that everyone is aware of the risks involved in using digital data and its protection.

Online applications these days can be accessed through desktops, laptops, cell phones, etc.
These applications are highly interconnected.

For instance, Using the same cell phone a user can update his status on a social media website.
He can transfer funds online the next minute.
He/she might also use the same cell phone to access their personal identification details from the government database.
To top it all, he/she might use the same email account for registering in various banking, social networking applications, etc.
A weak password to this account is a temptation for hackers.
By gaining access to this email account they might be able to access other applications linked with this account.
A vulnerable email account can make other applications vulnerable too.

What is Security?

Cyber Security

There is no such thing as absolute security.
The quality or state of being secure.
