CompTIA CyberSecurity Analyst (CySA) CSO-003 Mini Deep Dive

Learn host and OS hardening to reduce attack surface, covering Windows registry, config files, file permissions, encryption, and access controls with baseline configs and auditing.

Explore cloud identity and access management with a hands-on AWS IAM demonstration. Learn how to create users, groups, roles, and policies, enable MFA, and analyze permissions with Access Analyzer.

Master identity and access management essentials, including federation, transitive trust, and single sign-on with protocols like SAML and OpenID, plus mfa, pam, and casb for cloud and on-premises.

Understand encryption concepts, including symmetric and asymmetric methods, non-repudiation, PKI and digital signatures, and apply them to disk encryption and secure web traffic.

Explore indicators of malicious activity by examining network attacks, including APTs and man-in-the-middle threats, plus host and application attacks. Learn to identify social engineering tactics and resolve them.

Identify secure network design concepts and common attacks, from zero trust to lateral movement, and learn mitigation using NetFlow, endpoint protection, and access control.

Identify social engineering attacks such as phishing, whaling, and baiting, and understand obfuscation techniques that disguise URLs. Avoid them by validating domains, spotting misspellings, and using antivirus and password managers.

Explore tools and techniques to determine malicious activity, including Wireshark for network traffic, DLP systems for PII data, SIM tools, saw tools, log analysis, and JSON considerations for the exam.

Explore threat intelligence and threat hunting to identify threat actors, their tactics and procedures, collection methods, assess confidence levels, and deploy active defense and a honeypot to contain threats.

Explore standardized processes and operations for cybersecurity teams, compare siem and soar, explain stix language, and cover incident response lifecycle phases, stakeholders, threat feeds, and data enrichment use cases.

Explore security operations tools and tool sets—SIEMs, SOARs, monitoring tools, APIs, webhooks, and plugins—and the single pane of the glass for holistic visibility.

Explore asset discovery and scanning using map scans to identify devices by Mac addresses and fingerprinting tools, while planning scheduled scans with operations and networks, and reviewing Nessus and Openvas.

Master CVSS interpretation to prioritize vulnerability remediation and manage alert fatigue. Understand CIA triad implications, asset inventory, and vulnerability assessment for effective risk management.

Learn how threat models secure development by testing systems and identifying threats before they occur. Compare STRIDE, PASTA, VAST, TRIKE, and OCTAVE, with tools like OWASP Threat Dragon and Mtmt.

Learn the software development life cycle and how secure coding integrates security from requirements to deployment. Explore threat modeling, security design, and compliance testing with CERT and OWASP guidance.

Explore attack methodology frameworks, starting with the cyber kill chain, and identify the key frameworks every defender should know.

Explore the containment, eradication and recovery phase (phase three) of incident response, detailing actions to prevent spread, eradicate threats, restore operations, with central, distributed and coordinated teams.

Move through the cyber kill chain framework and the diamond model to map adversary activity, and apply evidence acquisition, chain of custody, non-repudiation, containment, eradication, recovery, and post-incident review.

Explore reporting vulnerabilities and incident response reporting and communications within domain 4.0 reporting and communication. Develop skills to clearly convey security findings through focused reporting and communications.

Explore vulnerability reporting and compliance reports. Identify inhibitors for remediation and examine metrics and KPIs.

Identify inhibitors to remediation, including MOUs, SLAs, and baselines with KPIs defined by SMART criteria, that can delay vulnerability remediation.

Declare incidents to notify stakeholders with documentation and channels like Slack or email, led by the CERT team, then follow the incident handling guide through detection, escalation, containment, and recovery.

Navigate the course closeout by tackling practice questions, reviewing the exam process, and planning continuing education to complete the CompTIA CySA CSO-003 mini deep dive.
