Security (WGU)
Information Security - CORRECT ANSWER-Protecting an organization's information
and information systems from unauthorized access, use, disclosure, disruption,
modification, or destruction.
Compliance - CORRECT ANSWER-Requirements that are set forth by laws and
industry regulations.
CIA - CORRECT ANSWER-Confidentiality, Integrity, Availability
Confidentiality - CORRECT ANSWER-Refers to our ability to protect our data from
those who are not authorized to use/view it
Integrity - CORRECT ANSWER-The ability to prevent people from changing your data
in an unauthorized or undesirable manner
Availability - CORRECT ANSWER-Refers to the ability to access our data when we
need it
Possession/Control - CORRECT ANSWER-refers to the physical disposition of the
media on which the data is stored. (tape examples where some are encrypted and
some are not)
Authenticity - CORRECT ANSWER-whether you've attributed the data in question to the
proper owner or creator. (altered email that says it's from one person when it's not -
violation of the authenticity of the email)
Utility - CORRECT ANSWER-refers to how useful the data is to you.
Attacks - CORRECT ANSWER-interception, interruption, modification, and
fabrication
Interception - CORRECT ANSWER-attacks that allow unauthorized users to access
your data, applications, or environments. Are primarily attacks against confidentiality
,Interruption - CORRECT ANSWER-attacks that make your assets unusable or
unavailable to you temporarily or permanently. DoS attack on a mail server, for example.
May also affect integrity
Modification - CORRECT ANSWER-attacks involve tampering with our asset. Such
attacks might primarily be considered an integrity attack but could also represent an
availability attack.
Fabrication - CORRECT ANSWER-attacks involve generating data, processes,
communications, or other similar activities with a system. Fabrication attacks primarily
affect integrity but could be considered an availability attack as well.
Risk - CORRECT ANSWER-is the likelihood that an event will occur. To have risk there
must be a
threat and vulnerability.
Threats - CORRECT ANSWER-are any events being man-made, natural or
environmental that could cause damage to assets.
Vulnerabilities - CORRECT ANSWER-are a weakness that a threat event or the threat
agent can take advantage of.
Impact - CORRECT ANSWER-takes into account the value of the asset being
threatened and uses it to calculate risk
Risk Management Process - CORRECT ANSWER-Identify assets, identify threats,
assess vulnerabilities, assess risks, mitigate risks
Defense in Depth - CORRECT ANSWER-Using multiple layers of security to defend
your assets.
Controls - CORRECT ANSWER-are the ways we protect assets. Three different types:
physical, logical, administrative
Physical Controls - CORRECT ANSWER-environment; physical items that protect
assets think locks, doors, guards, and, fences or environmental factors (time)
Logical Controls - CORRECT ANSWER-Sometimes called technical controls, these
protect the systems, networks, and environments that process, transmit, and store our
data
, Administrative Controls - CORRECT ANSWER-based on laws, rules, policies, and
procedures, guidelines, and other items that are "paper" in nature. They are the policies
that organizations create for governance. For example, acceptable use and email use
policies.
Preparation - CORRECT ANSWER-phase of incident response consists of all of the
activities that we can perform, in advance of the incident itself, in order to better enable
us to handle it.
Incident Response Process - CORRECT ANSWER-1. Preparation
2. Detection and Analysis (Identification)
3. Containment
4. Eradication
5. Recovery
6. Post-incident activity: document/Lessons learned
Detection & Analysis - CORRECT ANSWER-where the action begins to happen in our
incident response process. In this phase, we will detect the occurrence of an issue and
decide whether or not it is actually an incident, so that we can respond appropriately to
it.
Containment - CORRECT ANSWER-involves taking steps to ensure that the situation
does not cause any more damage than it already has, or to at least lessen any ongoing
harm.
Eradication - CORRECT ANSWER-attempt to remove the effects of the issue from our
environment.
Recovery - CORRECT ANSWER-restoring devices or data to pre-incident state
(rebuilding systems, reloading applications, backup media, etc.)
Post-incident activity - CORRECT ANSWER-determine specifically what happened, why
it happened, and what we can do to keep it from happening again. (postmortem).
Identity - CORRECT ANSWER-who or what we claim to be. Simply an assertion.
Authentication - CORRECT ANSWER-the act of providing who or what we claim to be.
More technically, the set of methods used to establish whether a claim is true
