- Ensures security measures extend throughout the supply chain, guarding against vulnerabilities originating from external partners or vendors.
- Constantly monitors infrastructure operations and conducts assessments to identify and mitigate potential risks or vulnerabilities.
4. Endpoint Security
Endpoint security focuses on securing individual devices or endpoints (such as laptops, desktops, smartphones, and tablets) from cyber threats. An example that demonstrates the importance of endpoint security is the ransomware attack on the healthcare provider, NHS (National Health Service), in 2017.
During the NHS cyberattack, ransomware known as WannaCry targeted endpoints that ran outdated versions of the Windows operating system. The malware encrypted files on infected devices and demanded ransom payments in exchange for decryption keys.
Key features of Endpoint Security:
- Shielding endpoints from viruses, malware, and other malicious software.
- Monitoring and controlling incoming and outgoing network traffic on endpoints.
- Ensuring timely updates and patches for software vulnerabilities on endpoints.
- Real-time monitoring of endpoint activities and immediate response to security incidents
5. Data Security
Data security involves protecting digital data from unauthorised access, theft, or corruption throughout its lifecycle. An example that illustrates the importance of data security is the Facebook-Cambridge Analytica scandal that surfaced in 2018.
In this incident, a third-party app collected user data from millions of Facebook profiles without their explicit consent. This data was later shared with Cambridge Analytica, a political consulting firm, for targeted political advertising purposes.
Key features of Data Security:
- Protects sensitive data by converting it into an unreadable format, only accessible with an encryption key.
- Restricts and manages access to data, ensuring that only authorised individuals can view or modify it.
- Alters or hides specific data elements to prevent unauthorised access while maintaining usability.
- Ensures adherence to data protection laws, regulations, and internal policies governing data usage and storage.
6. IoT (Internet of Things) Security
IoT (Internet of Things) security refers to the measures taken to safeguard the vast network of interconnected devices, sensors, and systems that comprise the IoT ecosystem. An illustrative example that highlights the significance of IoT security is the Mirai botnet attack in 2016.
The Mirai botnet exploited vulnerable IoT devices, such as internet-connected cameras and routers, by using default or weak credentials to infect them and recruit them into a botnet. These compromised devices were then used to launch massive distributed denial-of-service (DDoS) attacks, disrupting internet services worldwide.
Key features of IoT (Internet of Things) Security
- Implements strong authentication methods to ensure only authorised devices can access the network or IoT ecosystem.
- Secures data both in transit and at rest, preventing unauthorised access or manipulation of sensitive information.
- Ensures regular updates and patches for IoT devices to address cyber security vulnerabilities and maintain their resilience.
- Divide IoT networks into isolated segments to contain breaches and limit the impact of compromised devices.
- Prioritises user privacy by ensuring data collection and usage adhere to consent and privacy regulations.
7. Mobile Security
Mobile security refers to the methods and tools used to protect smartphones, tablets, and other mobile devices from security threats and vulnerabilities. An example that vividly illustrates the significance of mobile security is the case of the FaceApp controversy in 2019.
FaceApp, a popular mobile application that allowed users to apply various filters to their photos, gained widespread attention. However, concerns arose regarding its privacy and security practices. The app’s terms of service and privacy policy raised alarms over data privacy as it granted the app broad permissions to access and use user-generated content and images.
Key features of Mobile Security:
- Safeguards data on mobile devices through encryption, ensuring that even if the device is lost or stolen, data remains protected.
- Implements strong authentication methods like biometrics, PINs, or two-factor authentication to prevent unauthorised access.
- Enables remote management of devices, enforcing security policies, and ensuring compliance across the device fleet.
- Utilises solutions that proactively identify and mitigate mobile-specific threats like malware, phishing, or network attacks.
8. Network security
Network security refers to the measures and practices designed to protect a network infrastructure from unauthorised access, misuse, modification, or denial of network resources and data. An illustrative example of network security is the WannaCry ransomware attack that occurred in 2017, which exploited vulnerabilities in Microsoft’s Windows operating system.
WannaCry propagated through a network by exploiting a vulnerability in the Server Message Block (SMB) protocol, affecting unpatched Windows systems.

- Implementing measures to control and manage access to systems, data, and facilities.
- Protecting physical assets, locations, and infrastructure from unauthorised access or harm.
- Developing and enforcing security policies and procedures tailored to the organisation’s needs.
10. Zero Trust
Zero trust is a security concept centred around the principle of not automatically trusting anything inside or outside a network perimeter. Instead, it advocates for strict identity verification and continuous authentication to ensure secure access to resources, regardless of the location of the user or device. An example that illustrates the implementation of zero trust is Google’s implementation of BeyondCorp.
Google’s BeyondCorp is a zero-trust security framework that rethinks traditional network security models. Instead of relying on a trusted internal network and perimeter-based security, BeyondCorp focuses on verifying every access request, treating all network traffic as untrusted.
Key features of Zero Trust:
- Emphasises continuous authentication and verification of user and device identities.
- Divide networks into smaller, isolated segments to restrict lateral movement in case of a breach.
- Consistently evaluates and scrutinises network traffic and user behaviour for potential threats.
- Enables secure access to applications and resources regardless of the user’s location or device.
So this was all about types of cyber security. In the evolving landscape of digital threats, understanding and implementing securities for different types of cyber security attack measures remains pivotal in safeguarding our interconnected world.
