- Consider the following example: Your company's mail server sends you an email informing you that your password has been changed and that you must take action to confirm this. However, to the best of your knowledge, you have not changed the password. What's going on? What caused the password to be changed, and why was it changed? How did an attacker acquire the necessary information to properly reset the password? Was it a virus, and what systems was it infecting?Imagine that a virus was attached to an email that was sent to Jim, and that this email caused Jim to get infected with the virus. Are you able to provide a description of this attack, including the vulnerabilities, hazards, and those who committed it?SCENARIO 1: You have just completed a routine security audit on the company’s information systems, and you found several areas of vulnerability. For example, file permissions have not been updated in some time, no comprehensive password policy exists, and network traffic is not fully encrypted. You noted these areas, among others, in a report to your supervisor. The report included specific recommendations to fix the problems. Your supervisor responded by saying that budgets are tight right now, and she could not approve your requests to resolve these issues. As an IT professional, you are very uncomfortable with the risk level, but you have been unable to sway your supervisor. When you discussed the situation with a colleague, he said, “Why worry about it? If it’s good enough for her, it should be good enough for you.” What do you think of your colleague’s advice, and why? Is this an ethical question? If you are still is uncomfortable, what are your options? SCENARIO 2: You work for a…
- Imagine if a virus were to be attached to an email and delivered to Jim, causing him to become infected. Can you describe this assault in terms of its vulnerabilities, dangers, and the perpetrators?Think about a situation in which hackers got access to information by installing malware on the POS systems of more than a million credit and debit card terminals across the world. The initial malicious code had been caught by the firewall, and an alarm had been sent, but it had been disregarded. The hackers began downloading the information that had been gathered. Cyber thieves have gained access to the system in order to steal credit and debit card information. Because of an excess of notifications from its network security equipment, the company acknowledged that they had disregarded many of the warnings. What would you do if you were the organization's Chief Technical Officer (CTO) in order to alleviate the issue of alert overstimulation?Think about a situation in which hackers got access to information by installing malware on the POS systems of more than a million credit and debit card terminals across the world. The initial malicious code had been caught by the firewall, and an alarm had been sent, but it had been disregarded. The hackers began downloading the information that had been gathered. Cyber thieves have gained access to the system in order to steal credit and debit card information. The stolen credentials are insufficient to get access to the company's point-of-sale equipment. Are there any other tools or techniques the hackers may use in order to traverse the company's network and install the malware?
- Consider the following scenario: you get a message from your company's mail server informing you that the password for your account has been changed and that you must confirm the change. According to what you know, you have not altered the password! What may have motivated the password change, and how did it happen? Was it a virus, and if so, on which computers, that may have given an attacker with the information they needed to successfully reset the password?Consider the scenario that you are the system administrator of London School which is in Muscat. You found that on one of the staff computers installed with Spyware which are connected to the Local Area Network. Suggest any four prevention techniques for the malware mentioned in the scenario.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?
- Consider the following scenario: you receive a notification from your company's mail server informing you that the password for your account has been changed and that you must confirm the change. According to what you know, you have not altered the password! What may have motivated the password change, and how did it happen? Was it a virus, and if so, on which machines, that may have provided an attacker with the information they needed to successfully reset the password?A "distributed denial of service attack" is what it is termed, and it may be orchestrated by a single individual. How do you define it?It is incumbent upon you to authenticate the updated password in the event that the email server of the organization notifies you of a password modification. As of now, there have been no observable alterations made to the passwords. A novel passphrase has been enforced. Why? Which type of malware could potentially provide an unauthorized user with the necessary access to modify a password, if any?
