Which algorithm does the value from the previous question (ans = 6) indicate your shadow file used? SHA-256 SHA-512 MD5 Blowfish SHA-512 Will salts be the same between both accounts? no 00:42 04:07 What is a salt? salt is made up of random bits added to each password instance before its hashing. Salts create unique passwords even in the instance of two users choosing the same passwords salt is random data that is used as an additional input to a one-way ...

What are we trying to protect in CYSE? - CORRECT ANS Confidentiality, integrity and availability (of information, systems resources etc.) What is confidentiality? - CORRECT ANS unauthorized users cannot access sensitive information What is integrity? - CORRECT ANS Information is complete and uncorrupted What is availability? - CORRECT ANS Authorized users can get to the information or resources What is vulnerability? - CORRECT ANS a flaw, weakness or hole in a system or component What i...

For what might we use the tool Kismet? You use the kismet tool in order to find and detect wireless devices. Explain the concept of segmentation and why it might be done. We divide a network into multiple smaller networks each acting as its own small network called a subnet. Here we can control the flow of traffic. We may do this to prevent unauthorized network traffic or attacks from reaching portions of the network we would prefer to prevent access. What risks might be present ...

In a data breach (such as the OPM case) which security characteristic of data has been violated? Confidentiality Which of the following about vulnerabilities and threats is not true? A vulnerability or a threat, but not both, are required to create risk 00:17 04:07 Considering the CIA triad and the Parkerian hexad, which of the following is true? Parkerian is more complete but not as widely known Which of the following is not true about complex and automatically...

CYSE 6 fully solved latest 2023 (graded A+)For what might we use the tool Kismet? to detect wireless devices What is the difference between a stateful packet filtering firewall and a basic packet filtering firewall? A stateful packet filtering firewall tracks sessions between systems What tool mentioned in the text might we use to scan for devices on a network, to include fingerprinting the operating system and detecting versions of services on open ports? nmap What is th...

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...
