Fundamental cybersecurity practices – Protecting yourself and your organisation

Cybersecurity isn’t a buzzword reserved for tech giants and government agencies – it’s a vital shield that protects all of us in our digital world. From safeguarding your personal information to ensuring the smooth operation of entire organisations, cybersecurity is the invisible force standing between our most valuable data and the ever-evolving threats that seek to exploit it.

Cybersecurity refers to the practice of safeguarding computers, networks, software applications, and sensitive data from unauthorised access, cyberattacks, damage, or theft. It keeps you and your organisation safe from threats like phishing, malware, and ransomware. By maintaining robust cybersecurity measures, both individuals and organisations can reduce their vulnerability to digital threats, ensure the confidentiality and integrity of their information, and maintain business continuity in an environment where cyber risks are constantly evolving.

What does cybersecurity do?

Cybersecurity safeguards the sensitive information, online activities, and digital assets that are essential to our personal and professional lives. It keeps your bank accounts secure, your organisation’s systems operational, and your personal devices safe. 

As we become more connected and reliant on existing online structures, we open ourselves to more risks. One weak password or a single outdated system can lead to major consequences. 

Cyberattacks not only affect IT departments, they disrupt supply chains, damage reputations, expose customer data, and can even shut down critical services. Leading UK retail brand Marks & Spencer (M&S) recently reported a cyberattack that disrupted its online services and resulted in the theft of some customer data. Although no payment or account details were exposed, the breach has affected online operations and is expected to continue causing service delays into July. This is just one of many examples of how learning how to identify vulnerabilities and improve defenses is a must-have skill.

Understand common threats and vulnerabilities

Here are a few key risks to look out for:

• Phishing: Fake emails or messages that trick you into giving away personal data.
• Malware: Harmful software that infects devices or networks.
• Ransomware: Malware that locks you out of your systems until a ransom is paid.
• Insider threats: Risks that come from within your organisation.
• Unpatched software: Outdated programs that haven’t been updated with security fixes.

Being cybersecurity-aware means being ready, not scared.

Know the difference between active and passive reconnaissance

Reconnaissance is the first step in many cyberattacks. 

Active reconnaissance involves scanning or probing your systems. It’s noisy and easier to detect. 

Passive reconnaissance is quieter and collects information without directly interacting with your systems. When you understand how attackers think, you’re better prepared to stop them.

Know the difference between hackers and cybersecurity professionals

Hackers find weaknesses in systems to exploit them. Cybersecurity professionals find those same weaknesses to fix them. The difference is intent. Ethical hacking is a key part of cybersecurity, and it plays a vital role in protecting our digital environment.

Ethical hacking is also known as penetration testing or white-hat hacking. It involves simulating cyberattacks under controlled conditions to identify security flaws before malicious actors can exploit them. These professionals follow strict legal and professional guidelines, working with organisations to strengthen defences and improve system resilience.

Improve your cybersecurity habits

You can start building stronger digital habits today:

• Use unique, strong passwords for each account.
• Turn on two-factor authentication.
• Keep your devices and software up to date.
• Don’t click suspicious links or download unknown attachments.
• Use trusted antivirus software and firewalls.

When you understand how systems work, you’ll know how to protect them.
