What Is Cybersecurity and Why Is It Important?

Cybersecurity is something that every business or organisation needs to know about – and individuals too.

It’s the digital equivalent of securing your home, making sure that all access points are locked and alarm systems are switched on and regularly tested.

For businesses, good cybersecurity practices are absolutely critical. A data breach or a malicious attack on websites, cloud systems or communication networks could be disastrous. It could lead to huge financial losses, compliance breaches and serious damage to the company’s reputation.

This is why it’s well worth getting to grips with what cybersecurity is and why it’s so important.

What Is Cybersecurity?

Cybersecurity is the practice of protecting digital networks, systems and data. There are lots of potential threats that need to be defended against, including:

• Cyber attacks and hacks – attempts by criminals to break into systems, networks, or accounts to steal data, disrupt operations, or gain unauthorised access.
• Malware – this is where malicious software is installed without the user’s knowledge, where its purpose is to steal information, infiltrate systems and potentially even damage devices 
• Phishing – these are scams where attackers trick people into revealing sensitive information – such as passwords or payment details – usually through deceptive emails or messages.
• Ransomware – this is a particularly dangerous type of malware which locks or encrypts data, and demands payment for its release. 

Cybersecurity is able to defend against these threats, by putting safeguards, technologies and software in place to cover all bases. It’s all about multi-layered protection, spanning network and email security, endpoint protection to safeguard individual devices, identity and access management, data encryption and backup, and many other areas.

Why Cybersecurity Is So Important

Modern businesses run on digital systems, and they also rely on data. Unfortunately, this data – from customer details and financial information to intellectual property and internal communications – is a prime target for cybercriminals.

Unless your organisation is able to proactively and robustly safeguard its data and systems from malicious attacks, there could be serious (and expensive) consequences. 

These can include:

• Significant financial loss through ransom payments, theft, or fraud – in fact, recent data puts the cost of cybercrime for UK businesses at a staggering £30.5 billion
• Operational downtime that disrupts workflows, damages productivity and prevents trading
• Reputational damage that erodes customer trust
• Legal and regulatory consequences, particularly in relation to GDPR and data protection
• Long-term business disruption, which can be particularly damaging for smaller organisations with fewer resources.

How Does Cybersecurity Work?

At its core, cybersecurity aims to deliver on three key fronts – confidentiality, integrity and availability. 

Confidentiality is all about managing authorised data access and ensuring valuable data is safeguarded from theft or loss. Integrity refers to keeping data accurate and free from unauthorised changes – for example, an attacker could change bank details for payments, without the organisation being aware of it. 

The last principle is availability, which means ensuring that systems are up and running when they are needed. 

A number of practices are employed by cybersecurity specialists, including:

• Firewalls and network filtering
• Antivirus and endpoint protection
• Multi-factor authentication (MFA)
• Secure configuration and patch management
• Threat monitoring and detection systems
• Cybersecurity training for employees. 

Preventative vs. Reactive Security Measures

Best practice within cybersecurity is focused on being proactive and preventative, which means stopping attacks and breaches before they happen. It’s about closing the gaps that malicious third parties can use to find their way into your systems. 

Measures such as password management and access control, firewall and antivirus software updates, vulnerability patching and strong authentication policies can all stop threats in their tracks. 

However, there is also a place for reactive measures within cybersecurity. Even with robust defence solutions in place, there’s still always the risk of an attack or breach. Cybercrime is becoming more sophisticated every day, and it can be hard for some organisations to keep up. 

If a threat is detected, reactive measures aim to respond quickly and effectively. This is done through measures such as carrying out forensic investigation and analysis on the source of the attack, rapid patching and system updates, and containment procedures (for example, isolating a device infecting with malware). 

Business continuity and incident response plans are very important in these situations, as they enable pre-planned measures to be enacted quickly.
