How does a spear phishing attack differ from a general phishing attack? whether message has embedded javascript or not size of the message number of targets and custom messages whether message has malware attached or not - CORRECT ANS number of targets and custom messages Is it OK to use the same password for all of our accounts? yes because using different passwords is hard to remember no because a compromise of one account leads to a compromise of all accounts using the...

Cryptography is? The science of keeping information secure (confidentiality and integrity). Encryption is? A subset of cryptography, refers to the transformation of unencrypted data to encrypted data. Plaintext or cleartext is? Unencrypted data. (message) Ciphertext is? Encrypted data. Decryption is? The process of recovering the plaintext message from the ciphertext. Cryptanalysis is? The science of breaking through the encryption used to create the ciph...

Considering the CIA triad and the Parkerian hexad, which of the following is true? Parkerian is more complete but not as widely known Salting a password makes it hard to guess by brute force Cybersecurity countermeasure are the tools and techniques we use to reduce risk Which of the following was not stolen in the OPM breach? money In the Maroochy Shire, the actual threat was a disgruntled former employee What do we call the process in which the client aut...

How many total tcp/tcp6 ports are listening? (count each row as one) 7 How many total udp/udp6 ports are listening (you won't see "LISTEN" by any of these)? (count each row as one) 6 The value after the last colon in the "Local Address" column is the port number; are the port numbers the same for the tcp/tcp6 and udp/udp6 ports? no The rightmost column now shows PID/Program name; what is the program name associated with tcp port 22 (either one)? sshd The line...

CYSE 101 FINAL STUDY SET questions and correct answers 2023What is access control? A security technique that regulates who or what can view or use resources in a computing environment It enables administrators to manage access at a more granular level Authentication Authentication is the step after identification It is to determine whether the claim of the identity is true Because access control is typically based on the identity of the user who requests access to a resource, a...

CYSE 101 FINAL questions with complete solutions 2023Cybersecurity countermeasures are: the tools and techniques we use to reduce risk One vulnerability in air traffic control system case was unauthenticated messages What does non-repudiation mean? suffuncent evidence exists such taht a user cannot deny an action What is the Parkerian hexad compared to the CIA triad Parkenian has 6 elements including the 3 from the CIA but is not as widely known Why does access co...

CYSE 101 Midterm with complete solution 2023CYSE is concerned with What are the cyber components of a system? What are the threats and vulnerabilities of that system (i.e., risk)? How do we reduce the risk by designing in security? What to answer for Case Studies What happened? (the facts) "Summary here" What vulnerabilities were exploited? Ex: Unencrypted data and code at rest, exposed electronics, exposed cryptographic keys By what/whom and how (threat)? Ex: H...

CYSE 101 questions with complete solutions 2023Vulnerability vs. Threat A vulnerability is a weakness that can be use to harm us, meanwhile a threat is an entity that seeks to exploit a weakness and harm us. Logical Controls • Passwords • Encrptions • Firewalls • Intrusion Detection Systems • Logical Access Controls Utility usefulness of data Interception attack against confidentiality Concept of defense in depth for layers of confidentiality Data L...
