IAS Flashcards
reviewer for IAS midterm exam
When did the need for computer security arise?
During World War II with the development of the first mainframes.
What was the main purpose of these early mainframes?
To aid computations for communication code breaking.
How was physical access to these mainframes controlled?
Through badges, keys, and facial recognition.
What were the primary threats to information security in the early years?
Physical theft, espionage, and sabotage.
What was one of the first documented security problems outside these categories?
A software glitch mixing the password file with the message of the day file.
Which code-breaking machine did the Poles crack before World War II?
Earlier versions of the German Enigma machine.
What impact did breaking the Enigma code have on the war?
It allowed Allied forces to anticipate German actions.
How did the complexity of the Enigma machine change over time?
It became increasingly complex, especially the submarine version.
True or False: Information security in the early years was a complex process.
False. It was mainly physical security and document classification.
Why did the need for national security lead to more advanced security measures?
To protect sensitive military information and systems.
What does MOTD stand for?
Message of the day
Besides physical security, what other basic security measures were used early on?
Document classification schemes.
When was ARPANET developed?
The Cold War (June 3, 1968)
What drove the need for more complex information security measures during the Cold War?
The increased use of mainframes for sophisticated tasks.
What was the main limitation of data transfer between computer centers in the 1960s?
Mailing magnetic tapes, which was cumbersome and slow.
What organization initiated the development of a networked communication system in response to this need?
The Department of Defense’s Advanced Research Projects Agency (ARPA)
What was the name of the project that became the predecessor to the internet?
ARPANET
Who is credited as the founder of the internet?
Larry Roberts (developer of the ARPANET project)
What impact did the increased popularity of ARPANET have on security concerns?
It raised concerns about its potential misuse.
Who identified security vulnerabilities in ARPANET in 1973?
Robert M. “Bob” Metcalfe
