Security domain definition
A security domain is a set of resources and permissions, protected by a common security policy, that applies to specific applications, groups of objects, or environments. This framework applies consistent security measures across these areas to protect data, resources, and users. Each organization develops its own policies based on its needs, and these policies are reviewed periodically to ensure they remain effective.

Security domain types
- Frameworks and standards. Frameworks and standards provide security teams with a structured path to achieve security.
- Application security. Application security includes the security of all the apps that you and other users on your network use to complete tasks.
- Risk management. Risk management is a separate security domain that monitors, assesses, and manages the risks that organizations and their users are exposed to.
- Governance. Governance involves making decisions about which security policies and protocols an organization will use. It also includes the implementation of the policies and protocols throughout the whole network.
- Threat research. Threat research involves collecting and analyzing potential cybersecurity threats and attacks.
Examples of security domains
- Network security domain: Protects the network infrastructure, including firewalls, routers, and switches, to prevent unauthorized access and ensure secure communication.
- Application security domain: Focuses on securing software applications, including web applications, by applying measures like encryption and vulnerability testing to protect data and functionality.
- User access control domain: Manages user permissions and access rights to ensure that only authorized individuals can access specific systems, applications, or data.
- Cloud security domain: Protects data and applications hosted in cloud environments by applying policies and security measures such as encryption, access control, and monitoring.
- Data security domain: Focuses on protecting sensitive data, both in storage and during transmission, using encryption, backup, and secure access methods to prevent unauthorized exposure.
- Physical security domain: Protects physical infrastructure, such as data centers and hardware devices, by controlling access to facilities and implementing surveillance measures.
Security domain management
Security domain management involves overseeing and enforcing security policies, processes, and technologies within specific domains to protect data, resources, and systems. It’s a process of ensuring an organization’s security measures are effective, compliant, and evolving to address emerging threats. Key aspects of security domain management include:
- Policy development and compliance: Creating security policies tailored to the organization’s needs but also adhering to industry standards and regulations.
- Access control and risk management: Managing user access to resources and assessing potential risks to minimize vulnerabilities and prevent unauthorized access.
- Monitoring, auditing, and incident response: Continuously monitoring security systems, auditing logs, and responding swiftly to security breaches or incidents to minimize impact.
- Security awareness and training: Educating employees about security best practices and threats to ensure they follow security protocols and recognize risks.
- Technology integration and continuous improvement: Integrating new security technologies and regularly updating systems and processes to adapt to evolving security challenges.
