"Cybersecurity is the practice of protecting critical systems and sensitive information from digital attacks. Also known as information technology (IT) security, cybersecurity measures are designed to combat threats against networked systems and applications, whether those threats originate from inside or outside of an organization.
In 2020, the average cost of a data breach was USD 3.86 million globally, and USD 8.64 million in the United States."

"Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users via ransomware; or interrupting normal business processes.
Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative."

"Nowadays, using your private computer is not as secure as you think because you leave traces of your activities that anyone can find.
The Tails operating system provides essential facilities for you to hide your identity without getting caught by prying eyes.
You can install Tails on a USB stick which consists of several steps."

"There are, essentially, three main uses of PGP:
***Sending and receiving encrypted emails.
Verifying the identity of the person who has sent you this message.***
***Encrypting files stored on your devices or in the cloud.***
Of these three uses, the first – sending secure email – is by far the dominant application of PGP."
"A third use of PGP is to encrypt files. Because the algorithm used by PGP – normally the RSA algorithm – is essentially unbreakable, PGP offers a highly secure way of encrypting files at rest, especially when used alongside a Threat Detection and Response Solution. In fact, this algorithm is so secure that it has even been used in high-profile malware such as the CryptoLocker malware."
