What is cyber security? Give the exact Definition and Best Practices

Definition of cyber security

Cyber security is the use of technology, procedures, and policies to defend against cyber assaults on systems, networks, programmers, devices, and data.

Its goal is to limit the risk of cyber assaults and to safeguard against unauthorized use of systems, networks, and technology.

What is the significance of cyber security?

Security breaches are more expensive.

GDPR (General Data Protection) and DPA (Dpa) 2018 privacy legislation can result in hefty fines for enterprises that experience cyber security breaches. There are other non-monetary expenses to consider, such as reputational harm.

Cyber assaults are becoming more sophisticated.

Cyber assaults are becoming more sophisticated, with attackers employing a wider range of strategies. Social engineering, malware, and ransomware are examples of such threats.

Cybercrime is a multibillion-dollar industry.

According to The Secret Cost of Cybercrime, a 2020research conducted by McAfee as well as the CSIS (Centre for Global development) based on Vanson Bourne data, the global economy losses and over $1 trillion (roughly £750 billion) every year. Political, ethical, and societal motivations can all motivate attackers.

Who needs cyber security?

It is a fallacy to presume that cyber attackers are uninterested in you. Everyone who has access to the Internet need cyber security. This is due to the fact that the majority of cyber assaults are automated and seek to exploit general weaknesses rather than specific websites or organizations.

Examples of common cyber threats include:

Ransomware, botnet software, RATs (remote access Trojans), rootkits and bootkits, spyware, Trojans, viruses, and worms are examples of malware.

Backdoors that allow for remote access.

Formjacking is the practise of inserting harmful code into web forms.

Cryptojacking is the installation of unauthorised cryptocurrency mining software.

DDoS (distributed denial-of-service) assaults, in which servers, systems, and networks are flooded with traffic in order to bring them offline.

DNS (domain name system) poisoning attacks, in which the DNS is compromised and traffic is redirected to hostile sites.

Information security vs. cyber security

Information security is sometimes mistaken with cyber security.

The goal of cyber security is to keep computer systems safe against unauthorised access, as well as from being destroyed or rendered inoperable in other ways.

Information security is a larger category that encompasses the protection of all information assets, whether hard copy or digital.

The legal mandate for cyber security

Organizations must use suitable security measures to protect personal data under the GDPR and DPA 2018. Otherwise, you risk receiving hefty fines.

Every organization's cyber security is a vital business problem.
