domains.
Docker - ANSWER ✓ Uses Linux Containers for lightweight application
virtualization.
Docker Commit - ANSWER ✓ Creates snapshots of containers for incident
response.
Docker Diff - ANSWER ✓ Shows container changes from its images.
Docker Control Groups (CGroups) - ANSWER ✓ Control groups can be used by
containers to limit resource consumption of one or more containers.
Memory Limit Example - ANSWER ✓ -m 512m --memory-swap 1g limits the
max amount of memory to 512 MB and allows the use of memory swapping.
No Swap Example - ANSWER ✓ -m 512m --memory-swap 512m limits the max
amount of memory to 512 MB and disables swapping.
CPU Limit Example - ANSWER ✓ --cpus="1.5" limits the max allowed CPU use
to one and a half logical CPU cores.
Storage Limit Example - ANSWER ✓ --storage-opt size=100G limits the
maximum allowed space a container can use.
File Limit Example - ANSWER ✓ --ulimit nofile=10000:10000 limits the soft
and hard open file system limits.
Domain-Based Message Authentication & Conformance (DMARC) - ANSWER
✓ An email authentication protocol that builds on SPF and DKIM to provide
domain-level protection against email spoofing and phishing attacks.
Domain Generated Algorithm (DGA) - ANSWER ✓ Malware generated domain
names, such as evil.com, which can change frequently.
, Domain Keys Identified Mail (DKIM) - ANSWER ✓ An email authentication
method designed to detect forged sender addresses in emails using public-key
cryptography.
Due Diligence - ANSWER ✓ A process of investigation and evaluation of a
business or individual prior to signing a contract.
Dwell Time - ANSWER ✓ How long a system or network is compromised before
detection.
Dynamic Access Control (DAC) - ANSWER ✓ Access control that factors in
device, user attributes, and file classification, calculated on the fly.
Dynamic Access Device and User Claims (ABAC) - ANSWER ✓ Conditional
access based on attributes from Active Directory, requiring Kerberos armoring.
Dynamic Authentication - ANSWER ✓ Access control based on temporal,
geographical, behavioral, and frequency factors.
Dynamic Authorization - ANSWER ✓ Access control that can dynamically alter
permissions based on risk and reward.
Egress Analysis - ANSWER ✓ The study of preventing unauthorized data
movement out of a system or network.
EIGRP Neighbor Authentication - ANSWER ✓ SHA should be used
when supported, with MD5 as a reasonable fallback.
Centralized Logging - ANSWER ✓ A method for logging messages from all
network devices, including Cisco routers.
Encrypted File Systems (EFS) - ANSWER ✓ Using Windows PKI to back up the
master key in an HSM, with contents encrypted by a symmetric key.
Evil Twin - ANSWER ✓ A rogue access point masquerading as a legitimate
access point.
