An attack that degrades or denies services in an all-optical network (AON).

A method of service disruption by damaging optical fibers.

Service disruption by exploiting optical amplifiers in an AON.

Attacks including eavesdropping and traffic analysis in an AON.

A system's ability to withstand external disturbances.

Clearly defined objectives for evaluating a system.

The system being evaluated for robustness.

Attack at a wavelength switch affecting connections at the same wavelength.

Fiber optic networks that support various services like premium private lines, data center interconnect, IP links, and mobile fronthaul.

A high-bandwidth, low-latency network supporting multiple services.

A network foundation for network slicing using Flex-E and SRv6 features.

Full-service access network using optical splitters and access points

Attack that gathers information about the nature of network traffic.

Interception and later use of sent data.

Gaining access or privileges by impersonation.

Blocking or disrupting a network's services to users.

A framework for defining and simulating errors that a system might encounter during testing. It helps evaluate a system's robustness under stress.

Error Type describes the specific type of error (e.g., flipping bits in CPU registers). Error Location refers to where the error is injected, not necessarily where the fault appears.

This dimension considers when the error is injected and how long it lasts. It helps understand the impact of errors on different system states.

Choosing the specific tasks and activities that the system should be performing during testing. It helps simulate real-world scenarios.

A system that automatically detects malicious activities attempting to breach a network or computer system.

A system that deploys countermeasures to defend against identified intrusions and secure a computing environment.

Firewalls, Access Control, and Cryptography are the primary defense against intrusions, safeguarding networks and data.

Traditional firewalls are not effective against internal attacks like flooding, user-to-root attacks, and port scanning, as they only monitor network boundaries.
