    Study Notes

    Assessing the Need for Secure Programming

    • Cyber-attacks can be prevented by using secure programming
    • Examples of cyber-attacks include data breaches, hacks, and cyber warfare
    • Cyber warfare is the use of technology to attack a nation, causing comparable harm to actual warfare

    Open Source and Reliance on the Internet

    • Open source software provides freedom to:
      • Run the program for any purpose
      • Study how the program works and adapt it to your needs
      • Redistribute copies to help others
      • Improve the program and release improvements to the public
    • Access to the source code is a precondition for these freedoms
    • Reliance on the internet increases the need for secure programming

    Industry Regulations and Complexity of Networks

    • Industry regulations include:
      • Healthcare
      • Department of Defense
      • Data Protection
      • Financial institutions
    • Complexity of networks today includes:
      • Diverse network technologies
      • Misconfigurations
      • Lack of knowledge about the network makes managers downplay vulnerabilities

    Security

    • Security is holistic and consists of:
      • Physical security
      • Technological security
      • Operational security

    Physical Security

    • Physical security measures protect personnel, critical assets, and systems against deliberate and accidental threats
    • Physical assets include:
      • Information assets

    Technological Security

    • Application security includes:
      • Web browser
      • Web server
      • Database
    • OS security (host)
    • Network security

    Operational Security

    • Policies include:
      • Password policy – complexity
      • Social engineering awareness
    • Standards include:
      • How policies should be implemented and enforced
    • Procedures include:
      • Step-by-step instructions on how to implement policies
    • Guidelines include:
      • Recommendations relating to a policy

    Security Objectives - CIA Triad

    • Security is concerned with the protection of assets against threats
    • Threats related to confidentiality, integrity, or availability (CIA)
    • Attacks against CIA are called Disclosure, Alteration, and Destruction (DAD) attacks
    • A target is said to be secure when the possibility of undetected theft or tampering is kept to an acceptable level

    Security Goals

    • Authentication
    • Authorization
    • Confidentiality
    • Data/message integrity
    • Accountability
    • Availability
    • Non-repudiation

    Authentication

    • Authentication mechanisms use any of four qualities to confirm a user's identity:
      • Something the user knows
      • Something the user has
      • Something the user is
      • Something the user can do
    • Multifactor authentication

    Authorization

    • Authorization is the act of checking whether a user has permission to conduct some action
    • Access control list (ACL) is used by many operating systems to determine whether users are authorized to conduct different actions

    Confidentiality

    • Confidentiality is the protection of assets from unauthorized access

    Data/Message Integrity

    • Data/message integrity is the protection of assets from unauthorized modification or alteration

    Availability

    • Availability is the protection of assets from unauthorized denial or destruction
    • A denial of service (DoS) is an action that prevents or impairs the authorized use of networks, systems, or applications by exhausting resources

    Accountability

    • Accountability is the ability to determine who the attacker or principal is in the case that something goes wrong or an erroneous transaction is identified
    • Find out vulnerabilities, fix bugs, improve the application, and use digital forensics

    Non-Repudiation

    • Non-repudiation is the ability to ensure undeniability of a transaction by any of the parties involved
