Understanding Cybersecurity Threats
Cybersecurity threats can be systematically categorized using the STRIDE framework. STRIDE stands for Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege. Each category represents a unique type of security threat that can compromise a system.
Key Points
- Spoofing: Unauthorized access or impersonation of a user or system.
- Tampering: Unauthorized modification or manipulation of data or code.
- Repudiation: Ability to deny having acted, typically due to insufficient auditing or logging.
- Information Disclosure: Unauthorized access to sensitive information, such as personal or financial data.
- Denial of Service: Disruption of the system's availability, preventing legitimate users from accessing it.
- Elevation of Privilege: Unauthorized elevation of access privileges, allowing threat actors to perform unintended actions.
STRIDE Framework Details
Spoofing
Spoofing involves unauthorized access or impersonation of a user or system. This violates the Authentication policy.
Tampering
Tampering refers to unauthorized modification or manipulation of data or code. This violates the Integrity policy.
Repudiation
Repudiation is the ability to deny having acted, typically due to insufficient auditing or logging. This violates the Non-repudiation policy.
Information Disclosure
Information Disclosure involves unauthorized access to sensitive information, such as personal or financial data. This violates the Confidentiality policy.
Denial of Service
Denial of Service (DoS) disrupts the system's availability, preventing legitimate users from accessing it. This violates the Availability policy.
Elevation of Privilege
Elevation of Privilege involves unauthorized elevation of access privileges, allowing threat actors to perform unintended actions. This violates the Authorisation policy.
