A virtual private network (VPN) is a virtualized extension of a private network across a public network, such as the Internet.

It enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.

Applications running across the VPN may therefore benefit from the functionality, security, and management of the private network.

A security hacker is someone who seeks to breach defenses and exploit weaknesses in a computer system or network.

Hackers may be motivated by a multitude of reasons, such as profit, protest, information gathering, challenge, recreation, or to evaluate system weaknesses to assist in formulating defenses against potential hackers.

The subculture that has evolved around hackers is often referred to as the computer underground.

In cryptography, encryption is the process of encoding a message or information in such a way that only authorized parties can access it.

Encryption does not of itself prevent interference, but denies the intelligible content to a would-be interceptor.

In an encryption scheme, the intended information or message, referred to as plaintext, is encrypted using an encryption algorithm, generating ciphertext that can only be read if decrypted.

For technical reasons, an encryption scheme usually uses a pseudo-random encryption key generated by an algorithm.

It is in principle possible to decrypt the message without possessing the key, but, for a well-designed encryption scheme, considerable computational resources and skills are required.

An authorized recipient can easily decrypt the message with the key provided by the originator to recipients but not to unauthorized users.

A computer virus is a type of malicious software program ("malware") that, when executed, replicates by reproducing itself (copying its own source code) or infecting other computer programs by modifying them.

Infecting computer programs can include as well, data files, or the "boot" sector of the hard drive.

When this replication succeeds, the affected areas are then said to be "infected" with a computer virus.

The term "virus" is also commonly, but erroneously, used to refer to other types of malware.

"Malware" encompasses computer viruses along with many other forms of malicious software, such as computer "worms", ransomware, trojan horses, keyloggers, rootkits, spyware, adware, malicious Browser Helper Object (BHOs) and other malicious software.

The majority of active malware threats are actually trojan horse programs or computer worms rather than computer viruses.

The term computer virus, coined by Fred Cohen in 1985, is a misnomer.

Viruses often perform some type of harmful activity on infected host computers, such as acquisition of hard disk space or central processing unit (CPU) time, accessing private information (e.g., credit card numbers), corrupting data, displaying political or humorous messages on the user's screen, spamming their e-mail contacts, logging their keystrokes, or even rendering the computer useless.

However, not all viruses carry a destructive "payload" and attempt to hide themselves—the defining characteristic of viruses is that they are self-replicating computer programs which install themselves without user consent.

The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide.

It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.

The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing.
