When a stream cipher like RC4 is used twice with the same key, it becomes vulnerable to a ciphertext-only attack. In this type of attack, the attacker has access to several ciphertexts that are encrypted with the same key but does not know anything about the plaintexts. By analyzing these ciphertexts, an attacker can gain insights into the plaintext or even recover parts or all of it. References := Cisco Cybersecurity source documents or study guide (I need to search for specific references as I don’t have direct access to Cisco’s proprietary content)

 Phishing is considered a low-bandwidth attack because it does not require the use of significant network resources. Instead, it relies on social engineering to deceive individuals into providing sensitive information or clicking on malicious links, often through email or other communication methods1.

 SOC metrics in relation to security incidents typically refer to the time it takes to detect the incident. These metrics are crucial for evaluating the effectiveness of incident response and remediation efforts by SOC teams. For example, metrics like the Mean Time to Detect (MTTD) enable organizations to assess how quickly they can identify a security incident, which is essential for reducing the impact of the incident on the organization.
