Which of the following policies is a set of rules designed to enhance computer security by encouraging users to employ strong passwords and use them properly?
Correct Answer: D
A password policy is a set of rules designed to enhance computer security by encouraging users to employ strong passwords and use them properly. Password policies are account policies that are related to the users' accounts. Such policies are password-related settings that provide different constraints for the password's usage. Password policies can be configured to enforce users to provide passwords only in a specific way when they try to log on to their computers. These policies increase the effectiveness of the user's computers. Answer option C is incorrect. A group policy specifies how programs, network resources, and the operating system work for users and computers in an organization. Answer option A is incorrect. An information protection policy ensures that information is appropriately protected from modification or disclosure. Answer option B is incorrect. Remote access policy is a document that outlines and defines acceptable methods of remotely connecting to the internal network.
Question 87
In which of the following transmission modes is communication bi-directional?
Correct Answer: B
Question 88
A CCTV camera, which can be accessed on the smartphone from a remote location, is an example of _____
Correct Answer: B
A CCTV camera that can be accessed on a smartphone from a remote location typically uses the Device-to-Cloud communication model. This model involves devices that connect directly to the cloud where data is stored and processed. Users can access this data through an application on their smartphones, allowing for remote monitoring and control. This setup is common for IP cameras that transmit data over the internet, enabling users to view live footage or recordings from anywhere with an internet connection.
Question 89
John has implemented________in the network to restrict the limit of public IP addresses in his organization and to enhance the firewall filtering technique.
Correct Answer: D
Network Address Translation (NAT) is a network function that translates private IP addresses into a public IP address. This technique restricts the number of public IP addresses required by an organization, as multiple devices on a private network can share a single public IP address. NAT also enhances firewall filtering techniques by hiding the internal IP addresses from the external network, which adds a layer of security by making it more difficult for attackers to target specific devices within the organization's network. It is a common practice in network security to use NAT in conjunction with firewalls to manage the traffic entering and leaving the network, ensuring that only authorized access is permitted.
Question 90
Which of the following are the six different phases of the Incident handling process? Each correct answer represents a complete solution. Choose all that apply.
Correct Answer: A,B,D,E,F,G
Following are the six different phases of the Incident handling process: 1.Preparation: Preparation is the first step in the incident handling process. It includes processes like backing up copies of all key data on a regular basis, monitoring and updating software on a regular basis, and creating and implementing a documented security policy. To apply this step a documented security policy is formulated that outlines the responses to various incidents, as a reliable set of instructions during the time of an incident. The following list contains items that the incident handler should maintain in the preparation phase i.e. before an incident occurs: Establish applicable policies Build relationships with key players Build response kit Create incident checklists Establish communication plan Perform threat modeling Build an incident response team Practice the demo incidents 2.Identification: The Identification phase of the Incident handling process is the stage at which the Incident handler evaluates the critical level of an incident for an enterprise or system. It is an important stage where the distinction between an event and an incident is determined, measured and tested. 3.Containment: The Containment phase of the Incident handling process supports and builds up the incident combating process. It helps in ensuring the stability of the system and also confirms that the incident does not get any worse. 4.Eradication: The Eradication phase of the Incident handling process involves the cleaning-up of the identified harmful incidents from the system. It includes the analyzing of the information that has been gathered for determining how the attack was committed. To prevent the incident from happening again, it is vital to recognize how it was conceded out so that a prevention technique is applied. 5.Recovery: Recovery is the fifth step of the incident handling process. In this phase, the Incident Handler places the system back into the working environment. In the recovery phase the Incident Handler also works with the questions to validate that the system recovery is successful. This involves testing the system to make sure that all the processes and functions are working normal. The Incident Handler also monitors the system to make sure that the systems are not compromised again. It looks for additional signs of attack. 6.Lessons learned: Lessons learned is the sixth and the final step of incident handling process. The Incident Handler utilizes the knowledge and experience he learned during the handling of the incident to enhance and improve the incident-handling process. This is the most ignorant step of all incident handling processes. Many times the Incident Handlers are relieved to have systems back to normal and get busy trying to catch up other unfinished work. The Incident Handler should make documents related to the incident or look for ways to improve the process. Answer option C is incorrect. The post mortem review is one of the phases of the Incident response process.
