CompTIA® Security+® Exam Prep

Explore the CompTIA Security+ exam prep course introduction, detailing 90 questions in 90 minutes with a 720 passing score, and previewing chapters on threats, cryptography, identity and access management.

Compare attack types, actors, and tactics while exploring information security basics, risk, assets, and the cyber attack lifecycle from planning to actions on objectives, including social engineering and defense.

Explore the types of security controls—administrative, technical, and physical—and how preventive, detective, and corrective measures build defense in depth, with incident response and business continuity planning.

Assess security posture using software tools through reconnaissance, fingerprinting, and scanning to collect data, map assets, and identify vulnerabilities.

Explore basic cryptography concepts, including encryption and decryption, confidentiality, authentication, and integrity. Compare symmetric and asymmetric systems, discuss keys, hashing, digital signatures, and public key infrastructure.

Explore how a public key infrastructure uses private and public keys to issue and sign certificates, establishing a chain of trust via certificate authorities and managing lifecycles, storage, and revocation.

Learn to implement identity and access management controls by defining authentication, authorization, and accounting; apply multi-factor options, tokens, biometrics, and audit logging to secure access.

Implement identity and access management with least-privilege access, policy-driven authentication and authorization, and ongoing auditing and recertification across Active Directory, groups, and organizational units.

Explore implementing a secure network architecture with network access control, zones and segments, DMZs, and firewalls to isolate and protect critical assets.
