101. A vulnerability scanner is a) a prepared application that takes advantage of a known weakness. b) a tool used to quickly check computers on a network for known weaknesses. c) an application that captures TCP/IP data packets, which can maliciously be used to capture passwords and other data while it is in transit either within the computer or over the network. d) a situation in which one person or program successfully masquerades as another by falsifying data and thereby gaining illegitimate access.
John Martin, a highly skilled computer technician with a master's degree in computer science took a low profile evening job as a janitor at Kent Manufacturing Company. Since the position was low level no security clearance or background check was necessary. While working at nights, John snooped through offices for confidential information regarding system operations, internal controls, and the financial thresholds for trans-action that would trigger special reviews. He observed employees who were working late, type in their passwords, and managed to install a Trojan horse virus onto the system to capture the IDs and passwords of other employees. During the course of several weeks, john obtained the necessary IDs and passwords to set himself up in the system as a supplier, a customer, systems administrator, which gave him access to most of the accounting system’s functions. As a customer, John ordered inventory that was shipped to a rented building and later sold. As a system…
A computer system has a weak password protection and also has been allowed to access free internet network, explain in detail using combination of CMD command and python codes, to conduct simple vulnerability assessment of a software installed on a such computer system.
Take, for example, the vulnerability that was just discovered in the system that handles authentication and access management. How much would operating procedures have been altered if this were the case? Does the company retain a record of the money that it has blown through?
Suppose you receive a letter, which appears to come from your company’s mail server stating that the password for your account has been changed, and that an action is required to confirm this. However, as far as you know, you have not changed the password! What may have occurred that led to the password being changed? What type of malware, and on which computer systems, might have provided the necessary information to an attacker that enabled them to successfully change the password?
It's possible that a single individual is behind DDoS attacks, but the mechanics of these attacks are murky at best.
during a penetration test, Chris recovers a file containing hashed passwords for the system he is attempting to access. What type of attack is likely to succeed against the hashed passwords?
Assume that you will need to confirm that your account has been renewed after getting a message from the mail server that is associated with your organization. Yet, to the best of your knowledge, you have not altered the password in any way! The password was changed at some point for unknown reasons. What type of malware, and on what devices would it have been present, might have provided an adversary with the information they need to successfully reset the password?
Computer Science Describe how to investigate an intrusion incident such as a redirect attack on a Windows laptop, with malware upload, what would you likely find going through the laptop and network information (hint: going through pcap files, system logs, security logs, and registry hive (ntuser.dat, etc...), and the file looking for artifacts)? In your opinion, how would you likely validate findings (artifacts), to confirm their accuracy and significance, found on the system and network?
Critically examine the morality of the argument that individuals who create and distribute nonmalicious viruses and worms are doing the computing technology industry a good service because they expose vulnerabilities in systems which otherwise might go undetected. Thus, such individuals indirectly help to make computers secure because they force systems administrators to beef up their security apparatuses by creating patches and implementing other measures to prevent further attacks.
