According to charles pfleeger an information system is secure when – According to Charles Pfleger, an information system is secure when it protects against unauthorized access, use, disclosure, disruption, modification, or destruction of information.
Pfleger’s definition of information system security is based on the CIA triad of confidentiality, integrity, and availability. Confidentiality means that information is only accessible to authorized users. Integrity means that information is accurate and complete. Availability means that information is accessible to authorized users when they need it.
According to Charles Pfleger, an information system is secure when it can withstand unauthorized access, use, disclosure, disruption, modification, or destruction. This is true for any information system, whether it’s a large enterprise system or a small telephone system in an office complex . An information system must be secure in order to protect the confidentiality, integrity, and availability of its data.
Definition of an Information System
An information system (IS) is a set of interrelated components that collect, store, process, and distribute information to support decision-making, management, and operations in an organization.
According to Charles Pfleeger, an information system is secure when it protects against unauthorized access, use, disclosure, disruption, modification, or destruction of information. For example, a large company has an inspection system in place to ensure that its information systems are secure.
This system includes regular security audits, vulnerability assessments, and penetration testing. By implementing these measures, the company can help to protect its information systems from unauthorized access and other threats.
Components of an IS include hardware, software, data, processes, and people. Functions of an IS include data entry, data storage, data processing, information retrieval, and information dissemination.
According to Charles Pfleeger, an information system is secure when it maintains confidentiality, integrity, and availability. Much like a living being is an autonomous system , an information system must be able to protect itself from threats and maintain its own integrity.
By understanding the principles of information security, we can ensure that our systems are safe and secure.
Security of an Information System
Information system security (ISS) is the protection of information systems from unauthorized access, use, disclosure, disruption, modification, or destruction.
According to Charles Pfleeger, an information system is secure when it can resist unauthorized access, use, disclosure, disruption, modification, or destruction. Like how the 5 main tasks of an operating system keep your computer running smoothly, an information system’s security measures protect it from malicious attacks and ensure its integrity.
ISS is important because it ensures the confidentiality, integrity, and availability of information. Confidentiality means that information is only accessible to authorized individuals. Integrity means that information is accurate and complete. Availability means that information is accessible when needed.
According to Charles Pfleeger, an information system is secure when its confidentiality, integrity, and availability are protected. These three components are essential for any information system, as they ensure that data is kept confidential, accurate, and accessible. The fourth major component of an information system is security, which ensures that the system is protected from unauthorized access, use, disclosure, disruption, modification, or destruction.
Charles Pfleger’s Definition of Information System Security
Charles Pfleger defines information system security as “the process of protecting information systems from unauthorized access, use, disclosure, disruption, modification, or destruction.”
According to Charles Pfleeger, an information system is secure when it’s resistant to unauthorized access, use, disclosure, disruption, modification, or destruction. A procurement information system is an example of a secure information system, as it’s designed to protect sensitive data from unauthorized access and use.
Key elements of Pfleger’s definition include:
- Protection:ISS is about protecting information systems from threats.
- Unauthorized:ISS is concerned with preventing unauthorized access, use, disclosure, disruption, modification, or destruction of information systems.
- Information systems:ISS is concerned with protecting all aspects of information systems, including hardware, software, data, processes, and people.
Attributes of a Secure Information System
According to Charles Pfleger, a secure information system has the following attributes:
- Confidentiality:Information is only accessible to authorized individuals.
- Integrity:Information is accurate and complete.
- Availability:Information is accessible when needed.
- Accountability:Individuals are responsible for their actions within the information system.
- Assurance:There is a reasonable level of confidence that the information system is secure.
Threats to Information System Security, According to charles pfleeger an information system is secure when
Common threats to information system security include:
- Malware:Malicious software, such as viruses, worms, and Trojan horses, can damage or destroy information systems.
- Hackers:Individuals who gain unauthorized access to information systems to steal data or disrupt operations.
- Insiders:Employees or contractors who have authorized access to information systems but misuse their privileges.
- Natural disasters:Events such as hurricanes, earthquakes, and floods can damage or destroy information systems.
- Human error:Mistakes made by users can lead to security breaches.
Methods for Ensuring Information System Security
Methods for ensuring information system security include:
- Access control:Restricting access to information systems to authorized individuals.
- Encryption:Encrypting data to protect it from unauthorized access.
- Firewalls:Blocking unauthorized access to information systems from the internet.
- Intrusion detection systems:Detecting and alerting to unauthorized access attempts.
- Security awareness training:Educating users about information system security risks and best practices.
Challenges in Achieving Information System Security
Challenges in achieving information system security include:
- The increasing sophistication of threats:Threats to information system security are becoming more sophisticated and difficult to detect and prevent.
- The interconnectedness of information systems:Information systems are becoming increasingly interconnected, which makes them more vulnerable to attack.
- The lack of security awareness:Many users are not aware of the risks to information system security and do not take appropriate precautions.
- The cost of security:Implementing and maintaining information system security measures can be expensive.
Final Wrap-Up
Ensuring the security of information systems is a complex and challenging task. However, by understanding the threats to information systems and implementing appropriate security measures, organizations can protect their information assets and maintain the confidentiality, integrity, and availability of their information.
According to Charles Pfleeger, an information system is secure when it can resist unauthorized access, use, disclosure, disruption, modification, or destruction. This means that the system must be protected against a variety of threats, including both internal and external attacks.
For example, a manufacturer uses electrical fuses in an electronic system to protect against power surges. Similarly, an information system can use a variety of security measures to protect against unauthorized access, such as firewalls, intrusion detection systems, and access control lists.
