Upon establishing his new startup, Tom hired a cloud service provider (CSP) but was dissatisfied with their service and wanted to move to another CSP. What part of the contract might prevent him from doing so?
Answer: C
During a cybersecurity operation, a CEH professional discovered an unknown Bluetooth Low Energy (BLE) device actively transmitting pairing signals. The professional decided to breach the BLE device using a crackle. The device was seen pairing and exchanging keys, leading to the establishment of a secure connection. However, the professional only managed to capture LL_ENC_REQ and LL_ENC_RSP packets, but not the Long-Term Key (LTK). Which of the following best describes the professional’s next course of action?
Answer: D
Harper, a software engineer, is developing an email application. To ensure the confidentiality of email messages, Harper uses a symmetric-key block cipher having a classical 12- or 16-round Feistel network with a block size of 64 bits for encryption, which includes large 8 ֳ— 32-bit S-boxes (S1, S2, S3, S4) based on bent functions, modular addition and subtraction, key-dependent rotation, and XOR operations. This cipher also uses a masking key (Km1) and a rotation key (Kr1) for performing its functions. What is the algorithm employed by Harper to secure the email messages?
Answer: A
Peter, a system administrator working at a reputed IT firm, decided to work from his home and login remotely. Later, he anticipated that the remote connection could be exposed to session hijacking. To curb this possibility, he implemented a technique that creates a safe and encrypted tunnel over a public network to securely send and receive sensitive information and prevent hackers from decrypting the data flow between the endpoints. What is the technique followed by Peter to send files securely through a remote connection?
Answer: A
Bob wants to ensure that Alice can check whether his message has been tampered with. He creates a checksum of the message and encrypts it using asymmetric cryptography. What key does Bob use to encrypt the checksum for accomplishing this goal?
Answer: C
Which among the following is the best example of the hacking concept called "clearing tracks"?
Answer: D
A logistics company recently found that some of its fleet vehicles equipped with smart locking systems were compromised, leading to vehicle thefts. The cybersecurity team suspects that attackers captured unique signals emitted by the key fobs during regular usage. To effectively confirm and prevent this attack in the future, what should the security team prioritize?
Answer: A
What is the following command used for?
Answer: C
In a healthcare organization, the network security team detects unusual network activity, indicating advanced sniffing techniques used by a potential attacker. Upon investigation, it’s found that the attacker exploits vulnerabilities in medical imaging protocols to intercept patient data. The security team must identify the specific sniffing technique being used and take action to protect patient privacy. Considering the scenario, which sophisticated sniffing technique poses the greatest challenge for the security team, potentially compromising patient data security?
Answer: B
Following an attack on its mobile infrastructure, an e-commerce company is reconsidering its mobile security strategies. In an event where an attacker has been able to gain partial root access to the mobile application, which of these tactics will offer the most effective barrier to additional exploitation?
