Cyber Security CSIA
Well elaborated summarized study guide 2024
Information Security - ✔✔✔Hardware, operating system, and application software that work together
to collect, process, and store data for individuals and organizations
Risk - ✔✔✔Likelihood that something bad will happen to an asset
Threat - ✔✔✔Any action that could damage an asset
Vulnerability - ✔✔✔A weakness that allows a threat to be realized or to have an effect on an asset
CIA Triad - ✔✔✔Confidentiality (people can see it), Integrity (people who can edit it are able to edit),
Availability (make sure systems are always up and online)
End User - ✔✔✔The weakest link in the Security of IT Infrastructure
Internet of Things & its challenges - ✔✔✔The interconnection via the Internet of computing devices
embedded in everyday objects, enabling them to send and receive data.
Security, privacy, interoperability, legal+regulatory, e commerce + compliance, economic development
issues
BYOD and the challenge it presents - ✔✔✔Bring your own device. Issues with mobile computing.
Network, usability, security
, OSI Reference Model, layers, and uses - ✔✔✔Open Systems Interconnection (Physical, Data Link,
Network, Transport, Session, Presentation, Application)
LAN - ✔✔✔Local Area Network; Provide network connectivity for computers located in the same area
WAN - ✔✔✔Wide Area Network; Connect systems over a large geographic area
TCP/IP - ✔✔✔A suite of protocols that operate at both the Network and Transport layers of the OSI
Reference Model
Governs all activity across the Internet and through most corporate and home networks
Developed by the DoD to provide a highly reliable and fault-tolerant network infrastructure (security
was not a focus)
IP address - ✔✔✔IPv4 addresses
Four-byte (32-bit) addresses that uniquely identify every device on the network
Still the most common
IPv6 addresses
Are 128 bits long
Provide more unique device addresses
Are more secure
Firewall - ✔✔✔Controls the flow of traffic by preventing unauthorized network traffic from entering or
leaving a particular portion of the network
Business Impact Analysis - ✔✔✔An analysis of an organization's functions+activities that classifies
them as critical or noncritical
