first and most important step of operational security - ANSWER: identify our most
critical information assets

threat - ANSWER: something that has the potential to cause harm to us

ex: security controls not very rigorous that can allow one to easily change source
code

deterrent controls - ANSWER: designed to discourage those who might seek to
violate our security controls from doing so

monitoring is in place, violations for breaking the law..

, more complex security measures, such as the use of iris scanners, mantraps, and
identification badges

administrative controls - ANSWER: background checks, periodic drug tests

main method of ensuring availability - ANSWER: backups like RAIDs

subnet - ANSWER: small network divided from a larger network

firewall - ANSWER: a mechanism for maintaining control over the traffic that flows
into and out of our network

packet filtering - ANSWER: looks at the contents of each packet in the traffic
individually and makes a gross determination, based on the source and destination
IP addresses, the port number, and the protocol being used, of whether the traffic
will be allowed to pass.

Since each packet is examined individually and not in concert with the rest of the
packets comprising the content of the traffic, it can be possible to slip attacks
through this type of firewall.

stateful packet inspection - ANSWER: like packet filtering but able to keep track of
traffic on a granular level

will only allow traffic through that is part of a new or already established connection

knows when the connection has been closed and further traffic should not
legitimately be present

deep packet inspection - ANSWER: capable of analyzing the actual content of the
traffic that is flowing through them

proxy servers - ANSWER: serve as a choke point in order to allow us to filter traffic
for attacks or undesirable content such as malware or traffic to Web sites hosting
adult content

DMZ (demilitarized zone) - ANSWER: layer of protection between the device, such as
our mail server, and the Internet, and between the rest of our network and the
device

Signature based IDses - ANSWER: They maintain a database of the signatures that
might signal a particular type of attack and compare incoming traffic to those
signatures

works well, except when we encounter an attack that is new, or has been specifically
constructed in order to not match existing attack signatures
