Are flashcards effective for the SecurityX (CASP+) exam?

Yes. Flashcards use active recall — retrieving an answer from memory — which research shows is one of the most effective study methods, especially in short, spaced sessions. SecurityX is dense with terminology (cryptography, PKI, zero trust, frameworks, risk formulas), which is exactly what flashcards drill best.

What topics do the SecurityX (CASP+) flashcards cover?

All four CAS-005 domains: Security Engineering & Cryptography (symmetric/asymmetric crypto, PKI, HSM/TPM, post-quantum), Security Architecture (zero trust, segmentation, cloud shared responsibility, DLP), Security Operations (SIEM/SOAR, incident response, forensics, red/blue/purple teams), and Governance, Risk, and Compliance (SLE/ARO/ALE, risk treatment, due diligence, frameworks).

Are the SecurityX (CASP+) flashcards free?

Yes — 100% free, all four study modes, no paywall.

Do these flashcards match the current SecurityX (CASP+) exam blueprint?

Yes. The cards are organized to CompTIA's current CAS-005 exam objectives (CASP+ was rebranded SecurityX in 2024), covering all four scored domains in their official proportions, including applied cryptography, zero trust, and risk management.

Why is CASP+ now called SecurityX?

CompTIA rebranded the CASP+ certification as SecurityX in 2024 as part of its Xpert Series of expert-level credentials. It's the same advanced security practitioner certification; the current exam version is CAS-005, which replaced CAS-004. You'll see both 'CASP+' and 'SecurityX' used interchangeably, so these flashcards cover one and the same exam.

Should I use flashcards alone to pass SecurityX (CASP+)?

No — flashcards are for the terminology and concept layer, and they're excellent for that. But SecurityX is scenario-driven and includes hands-on performance-based questions (PBQs), so pair the cards with our free study guide for depth and the practice test for applied, exam-style questions before test day.

How should I sequence flashcards, the study guide, and the practice test?

Read a module in the study guide, drill that module's flashcards in Type and Quiz modes until recall is fast, then confirm with the practice test across scenario-level questions. Repeat per domain, leading with Security Engineering (31%) and Security Architecture (27%). It's a learn → recall → prove loop.

Encryption using one shared secret key for both encrypting and decrypting — fast, ideal for bulk data (e.g., AES); the challenge is securely distributing the key.

Asymmetric encryption

Encryption using a public/private key pair (e.g., RSA, ECC) — solves key exchange and enables digital signatures, but is slower than symmetric.

AES (Advanced Encryption Standard)

The modern, widely trusted symmetric block cipher used for bulk data encryption; supports 128-, 192-, and 256-bit keys.

A widely used asymmetric algorithm based on the difficulty of factoring large numbers; used for key exchange and digital signatures.

Elliptic Curve Cryptography (ECC)

Asymmetric cryptography that delivers equivalent strength to RSA with much shorter keys — efficient for mobile and constrained devices.

A key-exchange algorithm that lets two parties derive a shared secret over an insecure channel; the ephemeral variant (DHE/ECDHE) provides forward secrecy.

Cryptographic hash function

A one-way function mapping input of any size to a fixed-length, irreversible digest (e.g., SHA-256) — provides integrity, not confidentiality.

A secure 256-bit cryptographic hash from the SHA-2 family, used for integrity verification and digital signatures.

Hash-based Message Authentication Code — a hash combined with a secret key to provide both integrity and authenticity of a message.

A value created with a sender's private key that proves authenticity, integrity, and non-repudiation; verified with the sender's public key.

Assurance that a party cannot deny having performed an action — provided cryptographically by digital signatures.

Random data added to a password before hashing so identical passwords produce different hashes, defeating precomputed (rainbow-table) attacks.

Deliberately slow password hashing (bcrypt, PBKDF2, Argon2) that increases the cost of brute-force attacks.

Public Key Infrastructure (PKI)

The framework of CAs, RAs, and policies that creates, distributes, validates, and revokes digital certificates binding identities to public keys.

Certificate Authority (CA)

The trusted entity in a PKI that signs and issues digital certificates and can revoke them.

Registration Authority (RA)

The PKI entity that verifies a requester's identity before the CA issues a certificate.

Digital certificate (X.509)

A document binding a verified identity to a public key, signed by a CA so relying parties can trust the key.

Certificate Revocation List (CRL)

A published list of certificates a CA has revoked before their natural expiry.

Online Certificate Status Protocol — a real-time query to check whether a single certificate has been revoked, instead of downloading a full CRL.

A trusted anchor (e.g., a root CA or hardware module) from which a chain of trust is built.

Hardware Security Module (HSM)

A tamper-resistant device that generates, stores, and uses cryptographic keys inside a hardened boundary; keys never leave in plaintext.

Trusted Platform Module (TPM)

A chip embedded in a host for secure boot integrity measurement and hardware-backed key storage.

Storing a recoverable copy of cryptographic keys with a trusted third party for business continuity or legal access.

Perfect forward secrecy (PFS)

Use of ephemeral session keys so that compromise of a long-term private key cannot decrypt previously recorded sessions.

TLS (Transport Layer Security)

The protocol that secures data in transit (e.g., HTTPS) using a hybrid of asymmetric key exchange and symmetric encryption.

A protocol providing an encrypted channel for remote login and command execution.

SSH File Transfer Protocol — secure file transfer running over an SSH-encrypted channel.

A protocol suite that authenticates and encrypts IP traffic, commonly used to build VPN tunnels.

Post-quantum cryptography (PQC)

Algorithms designed to resist attacks by large quantum computers, which could break today's RSA and elliptic-curve cryptography.

Designing systems so cryptographic algorithms can be swapped out without re-architecting — essential for the post-quantum transition.

“Harvest now, decrypt later”

The threat of an adversary recording encrypted traffic today to decrypt it once quantum computers mature.

Homomorphic encryption

Encryption that allows computation on ciphertext without decrypting it, so data stays protected during processing.

An attack that tries every possible key or password until the correct one is found; defeated by large key spaces and key stretching.

When two different inputs produce the same hash output; resistance to collisions is why MD5 and SHA-1 are deprecated.

Hard-coding the expected certificate or public key in a client so it rejects any other, even from a valid CA.

A trusted execution environment that isolates sensitive code and keys from the main operating system.

A security model that removes implicit trust based on network location and verifies every request on identity, device, and context — “never trust, always verify.”

The zero-trust tenet of authenticating and authorizing every request on identity, device health, and context — no implicit trust from location.

The zero-trust mindset of designing as if an attacker is already inside — segmenting, encrypting, and monitoring to contain damage.

Layering multiple, overlapping controls (data, app, host, network, perimeter, people) so that if one fails, others still protect the asset.

Dividing a network into isolated zones (VLANs, subnets) so traffic between them passes through controls, limiting lateral movement.

Segmentation pushed down to individual workloads or hosts, enforcing zero-trust policy at a fine granularity.

The classic card. Do you know this one?

Click Study Flashcards above to open the flashcard hub — hundreds of SecurityX (CASP+) cards you can flip, match, type, or quiz yourself on. Every card is drawn from the four official CAS-005 domains, so you study exactly what the exam tests.^[2] Pair them with our free practice test and study guide.

CompTIA SecurityX (CASP+) is one of the 14 CompTIA certifications — explore our CompTIA flashcards to compare and prep across the whole family.

SecurityX (CASP+) Flashcard Study Modes

Four modes run on the same 136 cards. Flip is quiet study, one term at a time. Match is a timed term-to-definition game that rewards fast recognition. Type shows the definition and asks you to produce the term, so a front like OCSP has to come out of memory rather than off a list. Quiz turns the same cards into multiple choice.

Why Flashcards Work for SecurityX (CASP+)

Security Engineering & Cryptography carries 36 cards and the largest share of the exam at 31%, so it is the natural place to spend early sessions. The cards drill algorithm names, protocol choices, and the supporting vocabulary around key handling: RSA and SHA-256 sit next to HMAC, while Salt and Key escrow test whether you can explain a control rather than just recognize the word. IPsec and SFTP cover secure transport.

Security Architecture holds 32 cards against a 27% weight, and the terms lean toward design decisions and deployment models. Expect network segmentation and perimeter ideas such as VLAN and Air gap, modern access and edge concepts including SASE, ZTNA, and SD-WAN, plus cloud service model cards like IaaS and SaaS where the distinction is what the provider manages versus what you manage.

Security Operations also has 32 cards and 22% of the exam. These fronts cover the tooling and the people side of detection and response. SIEM and SOAR test whether you can separate aggregation from automation, Honeypot and Playbook cover deception and repeatable process, and exercise roles show up through Red team, Blue team, and White team. Legal hold pulls in evidence handling.

Governance, Risk & Compliance rounds out the deck with 36 cards and a 20% weight. The terms are frameworks, regulations, and legal standards you must tell apart under pressure: ISO 27001 and ISMS on the management system side, GDPR, HIPAA, and PCI DSS on the regulatory side, CMMI and ITIL as maturity and service management references, and Due care as a liability concept.

SecurityX (CASP+) is dense with terminology — cryptographic primitives, PKI, zero trust and segmentation, the incident-response lifecycle, security teams, and the SLE/ARO/ALE risk formulas.^[2] Spaced flashcards are the most efficient way to keep it all fresh. Used alongside our practice test and study guide, they turn review time into measurable progress.

SecurityX (CASP+) Flashcards by Domain

The cards are organized by the four official CAS-005 domains. Drill the highest-weighted ones first — Security Engineering and Security Architecture make up nearly 60% of the exam:^[2]

SecurityX (CASP+) flashcards by domain and weight
Domain	Exam weight
Security Engineering & Cryptography	31%
Security Architecture	27%
Security Operations	22%
Governance, Risk, and Compliance	20%

How to Get the Most Out of These Flashcards

Start heaviest. Open with the 36 cards in Security Engineering & Cryptography; it holds 31% of the exam and shares the largest card count, so early gains there pay off broadest.
Type-drill the lookalikes. Run HMAC and OCSP in Type mode until the definitions produce the term instantly, since related crypto acronyms are the easiest ones to confuse under time pressure.
Match the architecture acronyms. Use Match for fronts like SASE, ZTNA, and CASB, where the exam expects fast recognition of what each model controls rather than a long explanation.
Switch when Quiz stops surprising you. Once Quiz runs clean across Security Operations terms such as SIEM and SOAR, move to the practice test for scenario-length questions the cards cannot simulate.
Rotate, do not cram. Work one domain per sitting and cycle all four across the week, so the 136 cards stay in rotation; pair weak fronts with the study guide before returning.
