What is Cyber Security?

Everything you need to know about protecting your organisation from cyber attacks.

Cyber security definition

Cyber security is the application of technologies, processes and controls to protect systems, networks, programs, devices and data from cyber attacks.

It aims to reduce the risk of cyber attacks, and protect against the unauthorised exploitation of systems, networks and technologies.

Cyber security vs information security

Cyber security is often confused with information security.

  • Cyber security focuses on protecting computer systems from unauthorised access or being otherwise damaged or made inaccessible.
  • Information security is a broader category that looks to protect all information assets, whether in hard copy or in digital form.

The legal requirement for cyber security

The GDPR (General Data Protection Regulation) and DPA (Data Protection Act) 2018 require organisations to implement appropriate technical and organisational security measures to protect personal data – or risk substantial fines.

Cyber security is a critical business issue for every organisation.

The three pillars of cyber security

Cyber security should address people, processes and technology.

This holistic approach is essential: technological measures need processes to govern how they are used and staff training to ensure those processes are followed.



Every employee needs to be aware of their role in preventing cyber threats. Cyber security staff need to stay up to date with the latest risks, solutions and qualifications.



Documented processes should clearly define roles, responsibilities and procedures. Cyber threats are constantly evolving, so processes need to be regularly reviewed.



From access controls to installing antivirus software, technology can be utilised to reduce cyber risks.

Why is cyber security important?

The costs of cyber security breaches is rising

Privacy laws such as the GDPR and DPA 2018 can mean significant fines for organisations that suffer cyber security breaches. There are also non-financial costs to be considered, like reputational damage.

Cyber attacks are increasingly sophisticated

Cyber attacks continue to grow in sophistication, with attackers using an ever-expanding variety of tactics. This includes social engineering, malware and ransomware (used for PetyaWannaCry and NotPetya).

Cyber security is a critical, board-level issue

New regulations and reporting requirements make cyber security risk oversight a challenge. The board will continue to seek assurances from management that their cyber risk strategies will reduce the risk of attacks and limit financial and operational impacts.

Cyber crime is a big business

In 2018, the cyber crime economy was estimated to be worth $1.5 trillion, according to a study commissioned by Bromium. Attackers can also be driven by political, ethical or social incentives.


What are the consequences of a cyber attack?

Cyber attacks cost organisations billions of pounds and can cause serious damage. Impacted organisations stand to lose sensitive data, and face fines and reputational damage.

Cyber security checklist

Boost your cyber defences with these must-have security measures:

1. Staff awareness training

Human error is the leading cause of data breaches, so you need to equip staff with the knowledge to deal with the threats they face.

Staff awareness training will show staff how security threats affect them and help them apply best-practice advice to real-world situations.

2. Application security

Web application vulnerabilities are a common point of intrusion for cyber criminals.

As applications play an increasingly critical role in business, it is vital to focus on web application security.

3. Network security

Network security is the process of protecting the usability and integrity of your network and data. This is achieved by conducting a network penetration test, which scans your network for vulnerabilities and security issues.

4. Leadership commitment

Leadership commitment is the key to cyber resilience. Without it, it is very difficult to establish or enforce effective processes. Top management must be prepared to invest in appropriate cyber security resources, such as awareness training.

5. Password management

Almost half of the UK population uses ‘password’, ‘123456’ or ‘qwerty’ as their password. You should implement a password management policy that provides guidance to ensure staff create strong passwords and keep them secure.
