Accounting (also called auditing) tracks user activity like time spent and services accessed. The document provides details on different authentication methods like passwords, PINs, smart cards, and digital certificates. It emphasizes the importance of strong passwords and changing them regularly.
This document discusses several key concepts in information system security:
Authentication involves verifying the identity of a user or system, usually through passwords, ID cards, or biometrics. Authorization determines what resources a user can access after authentication. Privacy/confidentiality ensures sensitive personal data and messages are kept secret through encryption. Integrity keeps information from being altered without authorization. Availability ensures security services and data remain accessible. Non-repudiation prevents denied participation in online transactions. Auditing records network activity and communications for security monitoring through system logging.
This document discusses information system security. It defines information system security as collecting activities to protect information systems and stored data. It outlines four components of an IT security policy framework: policies, standards, procedures, and guidelines. It also discusses vulnerabilities, threats, attacks, and trends in attacks. Vulnerabilities refer to weaknesses, while threats use tools and scripts to launch attacks like reconnaissance, access, denial of service, and viruses/Trojans. Common attacks trends include malware, phishing, ransomware, denial of service, man-in-the-middle, cryptojacking, SQL injection, and zero-day exploits.
