Which domain of the CBSE curriculum specifically addresses vulnerabilities in Ethereum smart contract code?
Answer: Smart Contract Security
Smart Contract Security is the CBSE domain dedicated to identifying and remediating vulnerabilities such as reentrancy, integer overflow, and access control flaws in smart contract code.
The CBSE exam places emphasis on understanding threat modeling. Which framework is most commonly referenced for blockchain threat modeling in the curriculum?
Answer: STRIDE
STRIDE (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) is the most widely referenced threat modeling framework in blockchain security curricula including CBSE.
A CBSE candidate must understand 51% attacks. What resource does an attacker need to control to execute one on a Proof-of-Work network?
Answer: More than half of the network's total hashing power
A 51% attack on a Proof-of-Work blockchain requires an attacker to control more than 50% of the network's total hash rate, enabling double-spend and chain reorganization.
Which CBSE curriculum topic covers the security implications of using oracles in decentralized applications?
Answer: DeFi and Oracle Security
DeFi and Oracle Security is the CBSE domain that examines how oracles introduce off-chain data trust assumptions and can be manipulated to compromise on-chain logic.
According to the CBSE body of knowledge, which attack exploits a smart contract calling an external contract before updating its own state?
Answer: Reentrancy
A reentrancy attack occurs when a malicious contract repeatedly calls back into the vulnerable contract before the initial execution updates its balance or state, as seen in the 2016 DAO hack.
In the CBSE curriculum, which layer of blockchain architecture is primarily responsible for peer discovery and data propagation?
Answer: Network (P2P) layer
The Network or P2P layer handles peer discovery, block propagation, and transaction broadcasting across nodes in a blockchain network.
The CBSE exam expects candidates to know about cold wallet security. What is the primary security advantage of a hardware (cold) wallet over a software (hot) wallet?
Answer: It generates keys in a secure enclave never exposed to an internet-connected device
Hardware wallets store and use private keys within a secure, air-gapped chip that never exposes the key material to an internet-connected host, dramatically reducing remote attack exposure.
