FAQs
Q: What does cyber security do?
A: Cybersecurity protects systems, networks, and data from unauthorised access, damage, or theft.
This includes:
- Preventing cyberattacks (e.g. phishing, ransomware)
- Securing devices, websites, and cloud services
- Ensuring backups and recovery plans are in place
- Monitoring for threats and responding to breaches
For businesses, effective cybersecurity also includes staff training, password policies, secure Wi-Fi, and regulatory compliance, all tailored to reduce digital risk.
Q: What is the main role of cyber security?
A: The main role of cybersecurity is to reduce digital risk by protecting data, infrastructure, and systems from cyber threats.
This includes prevention (e.g. secure systems), detection (e.g. threat monitoring), and response (e.g. incident handling).
Ultimately, it’s about ensuring your technology can be used safely, reliably, and legally, especially where client data, financial records, or intellectual property are involved.
Q: What exactly does a cyber security person do?
A: A cybersecurity professional may:
- Monitor systems for suspicious activity
- Investigate security breaches or alerts
- Implement firewalls, antivirus, and access controls
- Test defences (e.g. via ethical hacking)
- Educate users on safe practices
- Write or enforce security policies
Their role depends on the business size and sector, in small firms, they wear many hats; in large organisations, they often specialise.
Q: What are the five main types of cyber security?
A: The five main types of cybersecurity align closely with risk areas across modern IT environments:
- Network Security – Secures internal systems using firewalls, intrusion detection, and VPNs.
- Information Security – Protects data privacy and integrity through encryption and access controls.
- Application Security – Defends apps from threats like SQL injection and cross-site scripting.
- Operational Security (OpSec) – Focuses on internal processes, user behaviour, and permissions.
- Disaster Recovery & Business Continuity – Ensures systems can recover from breaches or outages.
All five layers work together to protect business assets and maintain trust.
Q: What is ransomware and how can it be prevented?
A: Ransomware is a form of malware that locks or encrypts your files until a ransom is paid. It’s often delivered through phishing emails, infected downloads, or software vulnerabilities. Prevention includes using reliable antivirus software, keeping your operating system and apps updated, backing up data regularly (especially offline), training users to spot phishing attempts, and applying strong network security policies.
Q: What is the best defence against ransomware?
A: The best defence is a layered approach: keep all software updated, use a reputable antivirus, train staff on phishing awareness, and back up data frequently, with at least one copy kept offline. Network segmentation, multi-factor authentication, and limiting user permissions can further reduce the impact of an attack. Regular testing of your backup and recovery procedures is also essential.
