Tampering attack involves unauthorized physical or logical modification of a device, its firmware, or its software to change behavior, inject malicious code, or extract secrets. Relevant concepts: device/firmware integrity, secure boot and chain-of-trust, anti-tamper hardware (e.g., TPM, secure elements), and the distinction between network-layer attacks (Man-in-the-Middle, DDoS) versus endpoint compromise.

Step-by-step reasoning:
1. Identify symptoms implied by the scenario: persistent device misbehavior or altered firmware/behavior rather than simple traffic interception or service disruption. Those symptoms point to integrity compromise of the device itself, which is the hallmark of a tampering attack.
2. Map attack types to symptoms:
   - Man-in-the-Middle (MitM) intercepts or alters communications in transit but does not change device firmware/behavior.
   - DDoS aims to overwhelm resources and cause unavailability; it does not modify device internals.
   - Tampering modifies the device software/hardware—matching the scenario’s description of changed device behavior or unauthorized code.
3. Determine appropriate mitigations: Network defenses like firewalls or stronger encryption protect communications but do not prevent an attacker from modifying a device’s firmware. Secure boot and anti-tamper measures operate at device startup and hardware level to ensure only authenticated, signed firmware runs and to detect/prevent physical tampering—directly addressing tampering attacks.

Why the correct options are correct:
- "The attack in this scenario is Tempering attack" is correct because the core problem is modification of device/firmware integrity rather than interception or denial of service.
- "To prevent such kind of attack, we can deploy secure boot with anti-tamper measures" is correct because secure boot enforces a cryptographic chain-of-trust and anti-tamper hardware detects/prevents physical or firmware modification.

Why other options are incorrect:
- "Man-in-the-Middle attack" and "DDoS attack" do not modify device internals and therefore don’t match the observed tampering behavior.
- "Deploy firewall at the gateway" and "deploy strong encryption algorithm" protect network traffic but do not stop unauthorized firmware or hardware modifications.

Conclusion: The correct answers are "The attack in this scenario is Tempering attack" and "To prevent such kind of attack, we can deploy secure boot with anti-tamper measures", which matches the provided answer.
