Secure Data Storage
Ensuring all data stored in the cloud is protected against breaches with encryption, redundancy, and secure access controls.
Virtualization Security
Specific measures to protect the virtualized environments underpin cloud computing, including secure virtual network and hypervisor security.
8. Operational Security
Operational Security involves the processes and decisions for handling and protecting data assets. This includes:
Incident Response
The methodology an organization uses to respond to and manage a cyberattack.
Disaster Recovery and Business Continuity
Strategies that help organizations recover from cyberattacks and continue operations with minimal downtime.
User Training
Educating employees about how to identify and avoid security threats.
9. Cryptography
Cryptography secures information and communications through codes so that only those for whom the information is intended can read and process it. It encompasses:
Symmetric Encryption
Uses a single key for both encryption and decryption.
Asymmetric Encryption
It uses public and private keys to encrypt and decrypt messages.
Hash Functions
Used to ensure data integrity, converting information into a cryptographic hash representing it.
10. Physical Security
Physical security is essential to protecting the hardware and facilities that house computer systems, networks, and data. It encompasses:
Access Controls
Mechanisms like biometric scans, key cards, and PIN codes restrict physical access to sensitive areas.
Surveillance
CCTV cameras and other monitoring techniques detect unauthorized activities around secure facilities.
Environmental Controls
Systems to protect equipment from fire, flooding, and other environmental hazards.
11. Mobile Security
Mobile security has become increasingly important with the ubiquitous use of mobile devices. It protects personal and corporate information stored on smartphones, tablets, and laptops. Components include:
Mobile Device Management (MDM)
Software that allows IT administrators to control and secure mobile devices across an organization.
Mobile Application Management (MAM)
Focuses on securing individual applications by managing their deployment and updating.
Secure Wi-Fi
Protocols to ensure that connections over public or private Wi-Fi networks are secured against eavesdropping and data theft.
12. Supply Chain Security
Supply chain security addresses the risks introduced by third-party vendors and suppliers within an organization’s ecosystem. This includes:

User and Entity Behavior Analytics (UEBA)
Detecting deviations from normal behaviour to identify malicious or risky activities.
Predictive Analytics
Using machine learning models to predict potential threats based on historical data.
15. Zero Trust Security
Zero Trust is a security concept centred on the belief that organizations should not automatically trust anything inside or outside their perimeters. Instead, they must verify anything and everything trying to connect to its systems before granting access. This includes:
Microsegmentation
Dividing security perimeters into small zones to maintain access for separate network parts.
Least Privilege Access Control
Ensuring users have only the access they need for their job functions.
