Definition 1 of 273
ensures data is available when needed to authorized users
Exposure factor (ef)
quantitative decision making
Cascading (composition Theory)
Availability (CIA Triangle)
Definition 2 of 273
used to establish communication sessions between trusted partners; operate on the session layer
(layer 5); known as circuit proxies; manage comms based on the circuit, not the content of the
traffic
qualitative decision making
discretionary access controls
circuit level gateway firewalls
secure sockets layer (SSL)
,Definition 3 of 273
allows systems to support multicasting - the transition of data to multiple specific recipients; used
by IP hosts to register their dynamic multicast group membership; via IGMP a server can transmit
data for an entire group rather than a separate signal for each recipient; IP protocol field value is
2 (0x02)

Definition 4 of 273
verification that a person is who they say they are; ex: entering a password or PIN, biometrics, etc
- always a two step process with identifying
authorization
authentication
identification
non-repudiation
Definition 5 of 273
establishing, maintaining, and terminating communication sessions between two PCs; manages
dialogue control:
simplex: one way communication
half-duplex: two way communication but only one direction can send data at a time
full-duplex: two way communication - data can be sent both directions simultaneously
session layer (layer 5)

unicast transmission

Definition 7 of 273
Category A: Verified protection, the highest level of security
Category B: Mandatory protection
Category C: Discretionary protection
Category D: Minimal protection

Term 8 of 273
direct sequence spread spectrum (DSSS)
responsible for adding routing and addressing information to the data; accepts the
segment from the transport layer and adds information to it to create a packet
CPU supplied with the memory location address but indirect involves addresses who are
not on the same page as the current instruction running; may be used as an operand
counting the number of times each letter appears in the ciphertext
employs all available freq's in parallel (simultaneously); higher rate of throughput than
FHSS; uses an encoding mechanism (chipping code) to help reconstruct distorted data
, Term 9 of 273
statistical attack
long term plan that is fairly stable; defines the org's security purpose; useful to forecast
about 5 years and serves as a planning horizon - long term goals and vision (high level)
exploits statistical weakness such as floating point errors and inability to produce truly
random numbers; vulnerability in hardware
describes a system that is always secure no matter what state it is in; boots into a secure
state, maintains a secure state through all transitions, and allows subjects to access
resources only in a secure manner
required whenever industry or legal standards are applicable to your organization (NERC
CIP, FISMA)
Term 10 of 273
digital certificate standard X.509
certificates contain the following:
- version of X.509
- serial number
- signature algorithm identifier
- issuer name (the CA)
- validity period
- subject's name
- subject's public key
secure sockets layer (SSL) - VPN like security protocol that operates at the transport layer;
designed to support HTTPS but is capable fo securing any application layer protocol
derivative of PaaS; provides on demand online access to specific software applications or
suites without the need for local installation
to obtain legal restitution a company must demonstrate a crime was committed, suspect
committed that crime, and took reasonable efforts to prevent the crime
files are accurate, policy in place, proper authentication, compliance with laws and
regulation
