ICS-SCADA Dumps With Exact Questions and Answers

Industrial Control Systems (ICS) and SCADA networks typically operate in environments where the available bandwidth is limited. They are often characterized by:

Low processing threshold: ICS/SCADA devices generally have limited processing capabilities due to their specialized and often legacy nature.

Legacy systems: Many ICS/SCADA systems include older technology that might not support newer security protocols or high-speed data transfer.

Weak network stack: These systems may have incomplete or less robust network stacks that can be susceptible to specific types of network attacks.

High bandwidth networks are not typical of ICS/SCADA environments, as these systems do not usually require or support high-speed data transmission due to their operational requirements and the older technology often used in such environments.

A data diode is known as a prebuilt directional gateway that is unidirectional, designed specifically to allow data to travel in only one direction, ensuring secure one-way communication. This feature makes data diodes ideal for environments where it iscritical to prevent any possibility of data leakage or unauthorized access from an external network back to a secure network. Data diodes are commonly used in military and industrial applications, including ICS/SCADA systems, to protect sensitive information.References:

IPsec (Internet Protocol Security) primarily operates in two modes: Transport mode and Tunnel mode.

Transport mode: Encrypts only the payload of each packet, leaving the header untouched. This mode is typically used for end-to-end communication between two systems.

Tunnel mode: Encrypts both the payload and the header of each IP packet, which is then encapsulated into a new IP packet with a new header. Tunnel mode is often used for network-to-network communications (e.g., between two gateways) or between a remote client and a gateway.
