Twenty-five years ago, cybersecurity was not a conventional word in the vocabulary of IT. But it is now. In this chapter, you will get to know about the history of cybersecurity and how it came into existence.
Cybersecurity is all about reducing threats when people are in the process of dealing with technology. It encompasses the full range of protection against any online risk or vulnerability, which comprises information security assurance and cyber law enforcement.
Database security is the technique that protects and secures the database against intentional or accidental threats.

Rootkits are a collection of tools or sets of applications that allow the administrator-level access to a computer or a network. These rootkits are fed into the host computer by a cracker (malicious hacker) either by exploiting a known vulnerability of the system or cracking the password.
A computer virus is a program or a piece of code that is specifically designed to spread from computer systems to another computer and interfere with computer operation without the victim's knowledge.
System hacking is defined as the compromise of computer systems and software to access the target computer and steal or misuse their sensitive information. Here the malicious hacker exploits the weaknesses in a computer system or network to gain unauthorized access to its data or take illegal advantage.
Mostly, people talk about hacking from the attacking point of view and deal with logical security. Still, physical security is also a matter of concern from both malicious hackers and penetration tester's point of view. Penetration testing against physical targets is also a common phase of testing.
In other words, social engineering refers to the psychological manipulation of a human being into performing actions by interacting with them and then breaking into normal security postures.

Scanning is another essential step, which is necessary, and it refers to the package of techniques and procedures used to identify hosts, ports, and various services within a network.
Footprinting is the technique to collect as much information as possible about the targeted network/victim/system. It helps hackers in various ways to intrude on an organization's system.
