8. What is disaster recovery as a service? Combines the physical resources, such as servers, processors, and operating systems, from the applications. Combines multiple network storage devices so they appear to be a single storage device. Offers backup services that use cloud resources to protect applications and data from disruption caused by disaster. Combines networks by splitting the available bandwidth into independent channels that can be assigned in real time to a specific device.

Computer science Requests that are iterated and non-iterated, authoritative and root servers, and DNS records are all discussed in depth.
Let's consider a cybersecurity scenario in which we want to model the rate at which a system is targeted by cyberattacks over a certain period of time. Imagine a company's server being targeted by distributed denial-of-service (DDoS) attacks. These attacks flood the server with a large volume of traffic, causing it to become overwhelmed and unable to respond to legitimate requests. Based on historical data and network analysis, the average rate of DDoS attacks targeting the server is five per hour. What are the probabilities of experiencing different numbers of attacks (0, 1, and 2) within that hour? the calculus, and a explanation of your solution (calculus). please please dont use Ai tools answers by human logic.
A Network Security Design is necessary for a corporation to effectively protect its servers, since most of its operations are performed by servers on a flat network. A demilitarised zone is an option that has not been ruled out. If you could redesign the network from the ground up, what would you change?
The word "network security" refers to a wide range of technology, equipment, and procedures. In its most basic form, it is a collection of rules and settings that use both software and hardware technologies to safeguard the integrity, confidentiality, and accessibility of computer networks and data. Every company, regardless of size, sector, or infrastructure, needs network security solutions to defend itself from the ever-increasing panorama of cyber threats that exist today. Today's network architecture is complicated, and it must contend with a constantly evolving threat environment and attackers who are always looking for and exploiting weaknesses. These flaws may be found in a variety of places, including devices, data, apps, users, and geographic locations. As a result, several network security management tools and apps are now in use to handle specific threats and exploits, as well as regulatory non-compliance. Discuss why you believe network security is important. Are the…
Cybersecurity helps organizations to avoid attacks. It also helps to mitigate the risks if an attack occurs. For instance, network segmentation plays a vital role in reducing the risk of a cyber breach by isolating it. Explain the following: A. What does network segmentation mean; compare it to its flat network counterpart. B. Mention at least two of the best practices for network segmentation (i.e., what should be considered when segmenting an organization’s network)?
Network endpoints and network devices have different security considerations and implications. A user workstation implies certain security issues that remain in the User Domain while network implications remain part of the LAN or LAN-to-WAN Domain. However, during the course of investigating an intrusion, you may have to source data from logs kept in routing devices and end-user systems. Suppose an attacker intrudes upon one of your servers. How do you reconstruct the events of a crime? Log files are the first place to check for administrative issues and security activity. Log files help you put together a timeline of events surrounding everything from a performance problem to a security incident. You can also identify bad system or network activities by observing anomalies from baseline behavior or identifying certain suspicious actions. Testing ensures that your control and monitoring facilities work as intended and maintain proper operation. Monitoring ensures that you capture…
To protect the clouds, identity access management (IAM) is utilized in combination with the shared responsibility paradigm. In terms of context, I'm not sure what this implies.
Chart out two diagrams of networked computers. The first diagram should be a secure network, where all traffic can be checked by a computing device to ensure that it is safe. The second should be a reliable network, where there are many paths for packets to travel so that all packets reach their destination safely and quickly. Then, consider the following questions: What are the differences between these two networks? Do you think that the users of these two different kinds of networks would notice any differences between them? What factors might be affected by the layout of these two networks, and what kinds of tradeoffs to users experience when they choose reliability or security? Can you think of an example of a real-life network you might connect to, and which category it mostly falls into? Consider school internet networks, public Wi-Fi, or cellular data networks as you think of the different ways you connect to various internet networks.
DNS records, iterative and non-iterative searches, authoritative and root servers, and more are all included.
research a criminal case where digital evidence obtained from a network/internet was used to help reach a verdict. Give a brief summary of the case and describe how they impact the digital evidence had. How could errors in the chain-of-custody affect the admissibility of the evidence (e.g. Hashing the files pulled from a network stream. Please cite the source!
Answer all question Q. With the rapid developments of VolP systems, the security of these systems must be integrated with work-place security during the phase itself? Q. Encryption is a way to preserve the of VolP signals? Q. is for media encryption by providing encryption of the RTP media in real time communications namely conferencing and instant messaging? Q._ is affected when encryption requires an additional step of signal and media processing? Q. There should be good encryption mechanisms combined with to avoid attacks from anyone who has physical access to the office LAN?
Recognize the various types of DNS records. Each one should be thoroughly discussed, including examples of how and why they are employed. Is it feasible for a web server and an email server in the same firm to have the same hostname alias?
