Study Notes
Introduction to Information Security
- Definition of information security: A well-informed sense of assurance that information risks and controls are in balance.
- Modern computer security history began during World War II with code-breaking computations by the first mainframes.
- Early concerns centered on physical controls and limiting access to sensitive information in military locations.
History of Computer Security
- 1968: Maurice Wilkes discusses password security in "Time-Sharing Computer Systems."
- 1970: Willis H. Ware publishes "Security Controls for Computer Systems," highlighting the need for computer security. It was classified until 1979.
- 1973: Schell, Downey, and Popek emphasize the need for security in military systems in "Preliminary Notes on the Design of Secure Military Computer Systems."
- 1975: FIPS examines DES (Digital Encryption Standard) in the Federal Register.
- 1978: Bisbey and Hollingworth publish "Protection Analysis: Final Report," discussing vulnerabilities in operating system security and automated vulnerability detection.
- 1979: Morris and Thompson's paper "Password Security: A Case History" examines the design history of password security for remote systems.
- 1979: Dennis Ritchie addresses secure user IDs, secure group IDs, and system problems in "On the Security of UNIX" and "Protection of Data File Contents."
- 1982: The U.S. Department of Defense publishes the first version of TCSEC (Trusted Computer Security), known as the Rainbow Series.
- 1984: Grampp and Morris examine physical control, management commitment, employee education, and administrative procedures in "The UNIX System: UNIX Operating System Security."
- 1984: Reeds and Weinberger emphasize the vulnerability of security techniques to privileged users in "File Security and the UNIX System Crypt Command."
- 1992: The Internet Engineering Task Force develops the Simple Internet Protocol Plus (SIPP) Security protocols, now known as IPSEC security.
The 1960s
- The ARPA (Advanced Research Projects Agency) examines redundant network communications.
- ARPANET, developed by Larry Roberts, was the foundation of the internet.
The 1970s and 80s
- The ARPANET's growth revealed security issues like insecure dial-ups, lack of user identification, and absent authorization.
- Rand Report R-609 emerged as the foundation of computer security studies.
- Information security shifted focus from physical security to securing data, access control, and broader organizational involvement.
- MULTICS (Multiplexed Information and Computing Service) was designed with security integrated into core functions, influencing UNIX development.
The 1990s
- The Internet's growth created the need for secure communication between networks.
- Early internet security was a low priority.
- The DEFCON conference was founded for information security professionals.
2000 to Present
- The Internet's interconnectedness amplified security vulnerabilities.
- State-sponsored information warfare increased the need for improved security.
What is Security?
- Security is a state of being protected from harm or danger.
- Organizations need multiple layers of security for operations, infrastructure, people, functions, communications and information.
- The protection of information, systems, and hardware involved in its use, storage, and transmission.
- The CIA triangle (Confidentiality, Integrity, and Availability) is now considered inadequate.
- A comprehensive model includes other critical characteristics of information security.
