Layered Security
• Layered security implements different access controls and utilizing various tools and devices within a security system on multiple levels. • Compromising the system would take longer and cost more than its worth. • Potential downside is the amount of work it takes to create and then maintain the system.

Principles of Operating System Security
Principles of Operating SystemSecurityOperating system security is a critical aspect of ensuring the confidentiality, integrity, and availability of data within a computer system. The principles of operating system security are essential guidelines that help protect the system from unauthorized access, data breaches, and malicious attacks.One of the key principles of operating system security is the principle of least privilege. This principle states that users and processes should only be granted the minimum level of access and permissions necessary to perform their required tasks. By limiting access rights to only what is needed, the risk of unauthorized activities and potential security breaches is greatly reduced.Another important principle of operating system security is the concept of defense in depth. This principle involves implementing multiple layers of security controls to protect the system from various types of threats. By employing a combination of access control mechanisms, encryption, firewalls, intrusion detection systems, and other security measures, organizations can create a strong defense against potential security breaches.Access control is another fundamental principle of operating system security. Access control mechanisms, such as user authentication, authorization, and accounting, help ensure that only authorized users can access resources and perform specific actions within the system. By properly configuring access controls, organizations can prevent unauthorized access and maintain the confidentiality and integrity of their data.Auditing and monitoring are also critical principles of operating system security. Regular auditing of system logs and monitoring of network traffic can help organizations detect and respond to security incidents in a timely manner. By monitoring system activity and keeping detailed logs, organizations can identify suspicious behavior, track system changes, and investigate security breaches effectively.Secure configuration management is another important principle of operating system security. By ensuring that systems are properly configured, regularly updated, and patched with the latest security updates, organizations can reduce the risk of security vulnerabilities and exploits. Secure configuration management practices help maintain the overall security posture of the system and mitigate the risk of security incidents.Additionally, secure coding practices are essential principles of operating system security. By following secure coding guidelines and best practices, developers can create secure and robust applications that are less vulnerable to security exploits and attacks. Secure coding practices, such as input validation, secure error handling, and memory management, help prevent common security vulnerabilities, such as buffer overflows and injection attacks.In conclusion, the principles of operating system security are vital guidelines that help organizations protect their systems and data from security threats. By following these principles, organizations can establish a strong security posture, reduce the risk of security breaches, and safeguard the confidentiality, integrity, and availability of their data. Implementing robust security measures, such as least privilege, defense in depth, access control, auditing, monitoring, secure configuration management, and secure coding practices, can help organizations enhance the security of their operating systems and mitigate the risk of security incidents.。

第15章计算机伦理、道德与法规主要知识点：(1) 计算机伦理学(2) 计算机职业伦理规范(3) 职业理想与职业道德(4) 信息产业的法律法规本章重点：计算机职业伦理规范，职业道德，信息产业的法律法规本章难点：计算机职业伦理规范，信息产业的法律法规教学时数：2学时思维导论：15.1 计算机伦理学15.1.1 计算机伦理学概述计算机伦理学（computer ethics）是对计算机行业从业人员职业道德进行系统规范的新兴学科。
1．计算机伦理学的产生与发展1985年，美国著名哲学杂志《形而上学》发表了泰雷尔•贝奈姆的《计算机与伦理学》和杰姆斯•摩尔的《什么是网络伦理学》两篇论文，成为西方计算机伦理学兴起的重要标志。
美国学者斯平内洛在《信息技术的伦理方面》一书中提出了计算机道德是非判断应当遵守的三条一般规范性原则。
一是“自主原则”；二是“无害原则”；三是“知情同意原则”。
西方学者还对计算机“职业”、“职业人员”、“职业道德”的特殊性问题作了探讨。
2．建设计算机伦理的重要性信息时代的来临，迫切需要全社会高度重视计算机伦理的建设。
计算机技术依然处在探索与发展的过程中，必须借助人类特有的伦理智慧和道德精神的指引，才能防止研究与应用的急功近利，把技术上的“不确定性”对社会可能带来的危害降低到最低程度。
3．构建计算机伦理的基本原则（1）促进人类美好生活原则。
（2）平等与互惠原则。
（3）自由与责任原则。
（4）知情同意原则。
（5）无害原则。
4．计算机伦理学的内容（1）隐私保护。
（2）预防计算机犯罪。
（3）知识产权保护。
（4）软件盗版。
（5）病毒扩散。
（6）黑客。
（7）行业行为规范。
15.1.2 计算机职业伦理规范1．美国计算机伦理研究的实践美国计算机伦理问题研究中比较集中研究的现实道德问题有，计算机信息技术（包括软件、硬件、网络、专家系统）的知识产权问题，计算机犯罪、“黑客”与网络安全问题，信息与网络时代的个人隐私权的保护问题，信息技术产品对消费者和社会的责任问题，信息网络技术应用者个人的自由权利与道德责任问题，为控制国际互联网“色情音像”、“攻击言论”、“虚拟伤害”而建立审查制度的问题，企业信息技术与反不正当竞争的问题等。
可信计算机评估准则
可信计算机评估准则英文回答：The Trusted Computing Evaluation Criteria (TCE) was released by the National Information Assurance Partnership (NIAP) in 2004. It is an evaluation criteria for commercial off-the-shelf (COTS) information technology (IT) products that are designed to provide trusted services in support of security-sensitive applications.The TCE is based on the Common Criteria for Information Technology Security Evaluation (CC), which is an international standard for evaluating the security of IT products. The TCE extends the CC by adding requirements for trusted computing, such as:The ability to measure the integrity of the system.The ability to control access to the system.The ability to audit the actions of the system.The TCE is a voluntary standard, but it is often usedby governments and organizations to evaluate the securityof IT products.中文回答：可信计算评估准则（TCE）是由国家信息安全保障伙伴关系(NIAP) 于 2004 年发布的。

The cyber-criminal profile is not the stereotypical under-privileged person from an economically deprived household. household These cyber-criminals come from more affluent homes, with access to computers and Internet connectivity Teens and adolescents are committing the majority of computer crimes.
Can students indulge in questionable activities?? Might even be good students in school?
The Dilemma
Ryan & Ryan
Are we as IA educators only adding to the problem by teaching computer security vulnerabilities in our classrooms? Can we teach students to defend information infrastructures without teaching them how to attack such infrastructures either in theory or in practice?? We rely on the ready availability of useful tools ranging from scripting languages to programs and systems for cryptography, , firewall, , malicious code detection, , intrusion access control, detection, trusted networking, forensic analysis and a host of other relevant and valuable functions. Some student might abuse the information and techniques taught to them
