Which of these is a common form of removable storage?
Hard Disk Drive (HDD)
Solid State Drive (SSD)
USB Flash Drive
Network Attached Storage (NAS)
USB flash drives are portable removable storage devices commonly used to transfer files. SSDs and HDDs are internal or external drives but not typically considered removable like USB sticks.
AES is an acronym for which encryption standard?
Automatic Encryption System
Asymmetric Encryption Standard
Advanced Encryption Standard
Advanced Electronic Security
AES stands for Advanced Encryption Standard, a symmetric encryption algorithm widely used for securing data at rest and in transit. It was adopted by NIST in 2001.
What is the primary purpose of access control?
To encrypt stored data
To limit resource access to authorized entities
To classify data by sensitivity
To perform backups automatically
Access control enforces policies that allow only authorized users or processes to interact with resources. Encryption and backups are separate security measures.
Which backup type stores data changed since the last full backup?
Differential Backup
Full Backup
Synthetic Backup
Incremental Backup
A differential backup captures all changes since the last full backup. Incremental backups capture changes since the last incremental or full backup.
Which regulation governs personal data protection in the European Union?
HIPAA
PCI DSS
SOX
GDPR
The General Data Protection Regulation (GDPR) is the EU regulation that sets guidelines for the collection and processing of personal information. HIPAA covers US healthcare data.
Which risk is most associated with public cloud storage solutions?
Multi-tenancy data leakage
Printer sharing vulnerabilities
Physical theft of on-site hardware
Local file system corruption
Public clouds host data from multiple tenants on shared infrastructure, creating a risk of data leakage between tenants. Physical theft is more relevant to on-premises deployments.
Which protocol is primarily used to secure data in transit over the web?
SHA-1
AES
MD5
TLS
Transport Layer Security (TLS) is the standard protocol for encrypting data in transit on the web. AES and SHA-1 are cryptographic algorithms but not transport protocols.
Which access control model assigns permissions based on user roles?
Discretionary Access Control (DAC)
Attribute-Based Access Control (ABAC)
Mandatory Access Control (MAC)
Role-Based Access Control (RBAC)
RBAC grants permissions to users based on predefined roles, simplifying administration. DAC is owner-based, MAC is policy-driven, and ABAC uses attributes.
A storage strategy aims for near-zero Recovery Point Objective (RPO). Which technique achieves this?
Monthly backups
Synchronous replication
Differential backups
Asynchronous replication
Synchronous replication copies data in real time to a secondary site, ensuring minimal data loss and a near-zero RPO. Asynchronous replication has a data lag.
What is the main purpose of a data retention policy?
Determine how long data must be kept
Assign user access rights
Define encryption key lifecycles
Classify data by risk level
A retention policy specifies how long different categories of data must be stored before deletion. It supports compliance and storage management.
Which physical control is most effective for securing an on-premises data center?
Data encryption
Network segmentation
Badge access readers
Antivirus software
Badge access readers control who physically enters the data center, preventing unauthorized individuals from accessing servers. Antivirus and encryption address digital threats.
Which classification label typically applies to highly sensitive corporate data?
Internal
Public
Confidential
Archive
Confidential classification is used for highly sensitive data that requires strict access controls. Public data has no restrictions, and internal data is less critical.
Which strategy ensures off-site recovery capability after a primary data center failure?
In-memory caches
Off-site backups
Virtual private network tunnel
Local RAID arrays
Off-site backups store data at a separate geographic location, enabling recovery if the primary site fails. Local RAID protects against disk failures only.
What does tokenization do to sensitive data?
Compresses it for storage
Replaces it with a non-sensitive equivalent
Deletes the original records
Encrypts it with a public key
Tokenization replaces sensitive data with surrogate tokens, preserving format while removing the actual data. Encryption transforms data but tokens are random placeholders.
Which cloud deployment model provides physical server isolation for a single tenant?
Shared Virtual Private Cloud
Dedicated Host
Community Cloud
Public Cloud
A dedicated host allocates physical servers to a single tenant, providing isolation at the hardware level. Public and shared models host multiple tenants on the same hardware.
How does frequent encryption key rotation enhance data security?
It increases encryption performance
It simplifies backup procedures
It reduces storage overhead
It limits the window of exposure if a key is compromised
Regular key rotation limits how long a compromised key remains valid, reducing exposure. While it may add operational complexity, it strengthens overall security.
Which data storage resilience technique uses fragmentation and distribution?
RAID 0
Erasure Coding
Data Compression
Volume Snapshotting
Erasure coding breaks data into fragments, encodes it with redundant pieces, and distributes it across locations. This offers higher fault tolerance than RAID 0 or snapshots alone.
FIPS 140-2 compliance is primarily concerned with which aspect?
Outlining data classification levels
Defining access control policies
Validating cryptographic modules
Setting network segmentation rules
FIPS 140-2 is a U.S. government standard that certifies the security of cryptographic modules. It does not address access control or data classification directly.
Implementing least privilege in a hybrid cloud environment requires:
Granting root access to all administrators
Disabling multi-factor authentication
Allowing all inbound connections
Using role-based policies and network segmentation
Least privilege means users and services receive only the access necessary to perform their tasks. Combining RBAC with network segmentation enforces this across environments.
In data classification, which factor is least likely to determine sensitivity?
Legal and regulatory requirements
Data format (e.g., CSV vs database)
Strategic value to the organization
Potential business impact
Sensitivity is driven by legal, business, and strategic factors rather than the file format. CSV or database format does not inherently affect data sensitivity.

Cheat Sheet

  1. Understand Data Classification - Imagine your data as a library of secrets: some books are public, others are locked away. By sorting information into public, internal, confidential, and highly confidential tiers, you'll always know which security measures to apply. 12 Common Storage Security Best Practices for Enterprises and SMBs
  2. Implement Robust Encryption - Encryption is like translating your messages into a secret code only you and authorized friends can read. Always encrypt data both at rest and in transit using modern algorithms so prying eyes stay locked out. Essential Data Storage Security Best Practices to Know
  3. Enforce Access Controls - Role-based access control (RBAC) is your digital bouncer, ensuring only the right people get into the VIP section of your data. By assigning permissions based on roles, you reduce insider threats and keep sensitive files off-limits. Secure Data Storage Solution
