BASIC CONCEPTS OF CYBER SECURITY. ~ NIKHIL S. INTRODUCTION TO CYBER SECURITY.
[Audio] Cyber security involves protecting systems, networks, and data from digital threats. This can be achieved by adhering to three principles. The first principle is confidentiality, which ensures that sensitive information is accessible only to authorized users. The second principle is integrity, which ensures that data is accurate and unchanged, preventing unauthorized modification. The third principle is availability, which ensures that information and resources are accessible to authorized users when needed. These principles form the foundation of cyber security..
[Audio] Cybersecurity involves protecting systems, networks, and data from digital threats. This can be achieved by ensuring confidentiality, integrity, and availability. Confidentiality means that sensitive information is accessible only to authorized users. Integrity ensures that data remains accurate and unchanged, preventing unauthorized modification. Availability guarantees that information and resources are accessible to authorized users when needed..
[Audio] Authentication is the first step in securing a system. It involves verifying the identity of a user or device before granting access to resources. This is done using various methods such as passwords, multi-factor authentication, and biometrics. Once a user's identity has been verified, authorization comes into play. This is the process of granting or denying access to specific resources or actions. Finally, accounting keeps track of all user activities, allowing administrators to monitor and analyze system usage..
[Audio] Threats are anything that can harm or damage a computer system or network. These threats can take many forms, such as malware, viruses, hackers, and natural disasters. Risk is the potential harm or loss that could result from a cyber attack or data breach. It's the likelihood of something bad happening, and the severity of the impact if it does happen. An attack occurs when someone tries to harm a computer system or steal information. This can include hacking, phishing, and other types of malicious activity. Impact refers to the damage or consequences that occur if a threat exploits a vulnerability. This can include financial losses, reputational damage, and even physical harm..
[Audio] Individuals play a crucial role in protecting an organization's information systems and data. They are responsible for implementing measures to safeguard against cyber threats. This includes ensuring that the organization's digital assets are secure and protected from unauthorized access, modification, or destruction..
[Audio] The McCumber Cube is a framework that helps us analyze and manage cybersecurity. It has three main dimensions that we need to consider. These dimensions are confidentiality, integrity, and availability. We need to ensure that our information is secure, accurate, and accessible when needed. This cube gives us a comprehensive view of cybersecurity, allowing us to identify potential risks and take proactive measures to mitigate them..
[Audio] Data can exist in three states: storage, processing, and transmission. In the storage state, data is at rest, such as in databases or files. During processing, data is being used by active applications. When transmitting data, it is moving across networks. To protect this data, various measures are employed. These include technology-based solutions like firewalls and encryption, as well as policies and guidelines for managing security. Furthermore, education and awareness programs help users and staff understand the importance of cybersecurity..
