Disabling encryption for faster speeds

Which security measure can help protect sensitive data transmitted over a network from interception by unauthorized individuals?

Sharing data openly on public platforms

Using weak passwords for encryption

What is the purpose of conducting regular security audits in relation to computer security policy?

Identifying weaknesses and evaluating compliance with security standards

Ignoring potential security threats

What is the concept of least privilege in computer security policy?

Granting users only the minimum level of access required to perform their job functions

Granting all users unlimited access to all resources

Exposing sensitive information to external entities

Blocking access to essential systems and data

What is the purpose of a data backup policy in computer security?

To ensure data resilience and protection against data loss

To limit data access for all users

To share sensitive data openly without any restrictions

To intentionally delete all data

What is the purpose of a security incident response plan in computer security policy?

To outline procedures for addressing and mitigating security breaches or incidents

To shut down all systems in case of a minor issue

To ignore security incidents and avoid any action

To blame individual users for security breaches

Which of the following is NOT a recommended practice to enhance network security?

Implementing multi-factor authentication

What is the primary goal of network segmentation in a security policy?

To partition a network into smaller subnetworks to improve security

To allow unrestricted access to all network resources

To connect all devices on the same network for easier access

To disable all network security features for faster communication

What is the potential consequence of sharing network login credentials with others?

Increased risk of unauthorized access and security breaches

Improved collaboration and teamwork

Enhanced network performance and speed

Better protection of personal information

Which of the following activities is considered a violation of the acceptable use policy for the network?

Using the network for illegal activities or unethical behavior

Participating in online forums for academic discussions

Collaborating with classmates on group projects

Downloading software from authorized sources

What should users do if they encounter suspicious emails or messages on the network?

Report them to the IT department immediately

Engage with the sender to gather more information

Ignore them and delete the messages

Forward them to other users for awareness

The LMS has been an essential tool in curriculum design and development and in organizing factors that motivate student learning, especially in online distance learning. However, an LMS can be used in blended, hybrid, and in-class delivery modes. It is a software application designed to help in the administration of courses for both students and instructors. Such systems have been designed for use in learning and teaching activities (Chung et al., 2012). They also provide a variety of interaction methods between instructors and learners to facilitate the learning process better, You must remember well-designed LMS could also help improve student skills, such as effective online learning and self-direction (Norouzi, 2014). Students could use the system to enhance performance (perceived usefulness), and they could use such systems with little effort (perceived ease of use) (Venkatesh & Davis, 2000). A majority of higher education institutions have incorporated LMS systems; they have been used in university systems by schools, faculty members, and instructors (Klobas & McGill,. 2010), Because so much of higher education has been focused on course delivery Chapter3 INSTRUCTIONAL DELIVERY SYSTEMS AND EDUCATIONAL TECHNOLOGY i 71 in a physical classroom, the implementation of an LYS has a;ded institutons in transitioning to new online universe of curriculum de!ivery (Georgou!i, & Guerre. 2NS). Repositories, central databases, and online meeting 'oations are all characteristcs of a management system. As a concept, a 'earning management system is a broad idea and an example of technology's inabifity to be specific in terms of a definition. Several requirements a generat overview of what constitutes a leaming management system, such as those listed above Finally, end-user access is also a part of a learning management system with various levels being set up by security. For example, students have read-onty access, faculty members have read and write access, and technical staff has complete access for support and administrative duties (Graf & Chien, 2009). At its core, a learning management system contains internal or Web-based support and management for numerous aspects of learning and teaching (Hiary & Abu-Shawar, 2009). This allows access from numerous locales, usually on a 24-hour basis. When looking at a university or college, this concept begins to grow greatly depending on the organization's size and scope; department, and degree program. Leaming management systems also go by other names such as course management systems, and their use goes beyond higher education institutions to include businesses and individual instructors. Meis)ar-Tal, Kurtz, and Pieterse (2012) mentioned three primary purposes of an CMS. They include the following: 1. to provide students with digital learning materials; 2. to employ interactive learning activities with students in the forums; and 3. to manage the course and the learners. Faculty members who use an LMS to make available lecture notes and other classroom resources for their face-to-face class create a web-enhanced classroom experience. Regardless of its usage, requirements for classification as a learning management system include several key concepts like the availability of assets over networks, providing hosting, administration. and support. With the requirements set, utilization becomes the focal point. A fully utilized learning management system looks at use at the student level, faculty level, and administration level. proper utilization of learning management systems should mirror traditional higher education goals, enhancing students' experiences. For learninä management systems, this creates a central hub for a class activity. For some classes, all activities work in the learning management system, while others only use its resources for select activities.
