In cybersecurity, risk is represented by the combination of an asset, a threat, and a vulnerability. This means that for a risk to exist, there must be something of value (an asset) that could be negatively impacted, a potential source of harm (a threat), and a weakness that could be exploited (a vulnerability). The presence of an asset alone does not constitute a risk without the potential for a threat to exploit a vulnerability. Similarly, a threat without the ability to exploit a vulnerability does not pose a risk to an asset. Therefore,the representation of risk encompasses all three elements: the asset that needs protection, the threat that could cause harm, and the vulnerability that could allow the threat to affect the asset.

Circuit-level gateway firewall technology operates at the session layer of the OSI model. This type of firewall validates TCP or UDP sessions before allowing traffic through, without inspecting the contents of the data packets. It acts as a handshaking device between trusted clients or servers and untrusted hosts, ensuring that the session packets adhere to established rules for a connection. The session layer, which is Layer 5 in the OSI model, is responsible for setting up, managing, and terminating the connections between applications1234.

References: The information about the operation of circuit-level gateways at the session layer is supported by networking resources and documentation1234.

To provide an accurate answer, I would need to know the specific types of UPS and their corresponding uses and advantages as they relate to the options provided (i.e., 1-v, 2-iv, etc.). However, based on general knowledge, the three main types of UPS systems are:

• Standby UPS (Offline UPS): Provides basic protection and is suitable for less critical equipment or environments with fewer power fluctuations.
• Line-Interactive UPS: Offers a moderate level of protection with the ability to correct minor power fluctuations without switching to battery, making it suitable for business environments.
• Online UPS (Double Conversion UPS): Delivers the highest level of protection by continuously converting incoming AC power to DC and back to AC, ensuring a consistent and clean power supply suitable for critical and sensitive equipment.

Without the specific context or details provided in the question, it’s challenging to match these types to the given options accurately. Typically, the selection of a UPS type would depend on the criticality of the systems it’s protecting, the environment, and the budget available.

References: The general descriptions of the UPS types are based on industry-standard practices and can be found in various educational resources on UPS systems123.

Non-repudiation is a fundamental attribute of network defense that ensures that neither party can deny the authenticity of their communications. In the context of Simran’s actions as a network administrator, by mandating authentication before any connection establishment or message transfer, she is ensuring that the identity of the communicating parties can be confirmed and that the parties cannot later deny having sent or received the messages. This is crucial for maintaining accountability and trust within the network, as it provides irrefutable proof of the origin and integrity of the communications.

References: The concept of non-repudiation is widely recognized in cybersecurity and network defense literature as one of the key attributes that contribute to the security and integrity of digital communications. It is often discussed alongside other core principles such as integrity, availability, authentication, and confidentiality123.
