- CCST-C means Cisco Certified Support Technician - Cybersecurity, an entry-level Cisco credential tested by exam 100-160.
- Cisco lists exam 100-160 at 50 minutes with a USD 125 fee.
- The exam objectives are organized into five domains, from Essential Security Principles through Incident Handling.
- Cisco describes 150 hours of instruction and hands-on experience as preparation guidance, not a mandatory prerequisite.
The Short Answer: What CCST-C Actually Is
CCST-C stands for Cisco Certified Support Technician - Cybersecurity. It is an entry-level certification from Cisco Systems, Inc. that validates foundational knowledge of cybersecurity concepts, basic network security, endpoint protection, vulnerability and risk management, and incident handling. The credential is earned by passing a single exam, 100-160, which Cisco publishes as part of its CCST program.
Because several unrelated credentials in the industry share similar abbreviations, it helps to be precise: everything on this site refers only to the Cisco credential. If you want a deeper treatment of the name itself, our explainers on what CCST-C stands for and the meaning of CCST-C cover the terminology, while the CCST-C certification overview looks at the credential as a whole.
The certification is designed as a starting point. Cisco's own objectives document frames the successful candidate as someone with introductory knowledge and some hands-on exposure, not a seasoned security engineer. That positioning shapes everything about the exam: the vocabulary is broad, the scenarios are practical, and the expectation is that you can recognize and explain core security ideas rather than design enterprise architectures.
Where CCST-C Sits in the Cisco Certification Family
Cisco offers more than one certification with "CCST" or cybersecurity in the name, and candidates regularly confuse them. The table below separates the three you are most likely to encounter.
| Credential | Focus | Relationship to CCST-C |
|---|---|---|
| CCST Cybersecurity (CCST-C) | Entry-level security fundamentals across principles, network security, endpoints, risk, and incident handling | The subject of this site; exam 100-160 |
| CCST Networking | Entry-level networking fundamentals | A separate CCST exam with a different objective set |
| Cisco CyberOps Associate | Security operations and monitoring at the associate level | A distinct certification, not the same as CCST Cybersecurity |
Think of CCST Cybersecurity as the on-ramp. It introduces the vocabulary and mental models that later security-operations coursework builds on, but it is its own credential with its own exam, not a renamed version of anything else in the catalog.
Exam 100-160 at a Glance
The verifiable logistics are short. Cisco lists exam 100-160 as a 50-minute exam with a fee of USD 125. Registration runs through Certiport and Pearson VUE, the delivery channel Cisco points candidates to for the CCST Cybersecurity exam. You can review the official Cisco exam page and the Certiport scheduling page for the current booking flow in your region.
Equally important is what is not established in the official materials we rely on. The objectives document does not give official percentage weights for the five domains, and the sources here do not establish an official question count or a numeric passing score. Treat any site that quotes a precise passing percentage or domain weighting as unverified unless it cites Cisco directly. For a candid look at how scoring information is handled, see our article on the CCST-C passing score, and for money questions beyond the exam fee, the CCST-C certification cost breakdown walks through the pricing picture.
Scheduling windows and availability can vary by testing location, so confirm timing through the booking portal; our guide to CCST-C exam dates and scheduling explains what to look for.
Is there a prerequisite?
Cisco's introductory material describes successful candidates as having roughly 150 hours of instruction and hands-on experience. That figure describes expected preparation, and it is not presented as a mandatory gate you must clear before registering. In practice, that means you can sit the exam without formal coursework, but you should honestly measure whether your background matches what the objectives assume. Our CCST-C requirements guide unpacks eligibility in more detail.
The Five Objective Domains Explained
Everything on exam 100-160 maps to five official domains. Here is what each one actually asks you to know, using Cisco's own objective language as the guide. For a longer walkthrough of all five areas, read our complete guide to the CCST-C exam domains.
Domain 1: Essential Security Principles
The conceptual foundation. You define core terms and then apply them to threats, access control, and cryptography.
- Vulnerabilities, threats, exploits, risks, attack vectors, hardening, and defense-in-depth
- The CIA triad: confidentiality, integrity, availability
- Social engineering variants: phishing, spear phishing, vishing, smishing, and tailgating
- Malware, ransomware, denial of service, botnets, man in the middle, insider threats, and APTs
- AAA, RADIUS, multifactor authentication, and password policies
- Encryption types, hashing, certificates, PKI, and data in transit, at rest, and in use
Domain 2: Basic Network Security Concepts
Where security meets networking. Expect questions that require you to see how protocol behavior creates risk.
- Weaknesses in TCP, UDP, HTTP, ARP, ICMP, DHCP, and DNS
- IPv4 and IPv6 addressing, MAC addresses, CIDR notation, NAT, and network segmentation
- DMZ, virtualization, cloud, honeypots, proxy servers, IDS, and IPS
- Securing a SoHo wireless network: MAC filtering, encryption standards, and SSID considerations
- Secure access technologies: ACLs, firewalls, VPNs, and NAC
Domain 3: Endpoint Security Concepts
The device-level domain, covering operating systems, tooling, policy compliance, patching, and logs.
- Windows, macOS, and Linux security features, Windows Defender, host-based firewalls, CLI, PowerShell, permissions, and privilege escalation
- Assessment tools such as netstat, nslookup, and tcpdump
- Policy verification: hardware and software inventory, backups, PCI DSS, HIPAA, GDPR, BYOD, encryption, and configuration management
- Updates and patching for operating systems, applications, drivers, and firmware
- Reading Event Viewer, audit logs, syslog, and spotting anomalies
- Malware removal: scanning, reviewing scan logs, and remediation
Domain 4: Vulnerability Assessment and Risk Management
How organizations find weaknesses, rank them, and plan for the worst.
- Vulnerability identification, management, and mitigation; active versus passive reconnaissance; port scanning and automation
- Threat intelligence: CVEs, vulnerability databases and their limitations, cybersecurity reports and news, subscription services, and secure documentation sharing
- Risk management: vulnerability versus risk, ranking risks, mitigation strategies, risk levels, and data classification
- Disaster recovery and business continuity: DRP and BCP features, natural and human-caused disasters, and backup controls
Domain 5: Incident Handling
What happens when something goes wrong, from detection through response and reporting.
- Monitoring security events, escalation criteria, and the roles of SIEM and SOAR
- Packet captures, log entries, and identifying suspicious activity
- Digital forensics and attribution: Cyber Kill Chain, MITRE ATT&CK, the Diamond Model, TTPs, evidence sources, artifacts, preservation, and chain of custody
- Compliance impact on incident handling: GDPR, HIPAA, PCI-DSS, FERPA, and FISMA reporting and notification
- Incident response elements and lifecycle stages drawn from NIST Special Publication 800-61
Hands-On Skills the Exam Expects You to Recognize
CCST-C is a knowledge exam, but its objectives are written around things technicians actually do. That is why hands-on practice pays off even when the test itself is not a lab. A few concrete areas deserve attention.
Command-line and endpoint tooling
Domain 3 names netstat, nslookup, and tcpdump explicitly. You should be able to describe what each reveals: active connections and listening ports, DNS resolution behavior, and captured packet traffic. Running them yourself, even briefly, makes the exam's tool-recognition questions far easier than reading about them. The same goes for navigating file and directory permissions and understanding how privilege escalation happens.
Reading logs and spotting the odd one out
Interpreting Event Viewer entries, audit logs, and syslog is a named objective. Practice distinguishing routine noise from a suspicious pattern, because Domain 5 builds on exactly this skill when it asks when an event should be escalated.
Frameworks you should be able to place
The objectives mention the Cyber Kill Chain, MITRE ATT&CK, the Diamond Model, and the NIST 800-61 incident response lifecycle. At this level you are expected to explain what each framework is for and where it fits, not to apply it to a complex investigation. Knowing which framework describes attacker phases, which catalogs tactics and techniques, and which defines response stages is the practical goal.
Key Takeaway
Pair every concept with a tool or a setting. When you read about segmentation, picture an ACL or a DMZ; when you read about log analysis, open Event Viewer or review syslog entries. The exam's scenarios reward that kind of linked recall.
Who Should Take It and Where It Leads
CCST-C suits people at the start of a security path: students, career changers, help desk and IT support staff who want to move toward security, and junior technicians who already touch endpoints and networks. Because it is explicitly entry-level, it works as a structured way to learn the vocabulary employers expect before pursuing deeper credentials.
Roles that value this foundation tend to sit near the front lines: support and service desk positions with a security slant, junior security or SOC-adjacent roles, and IT generalist jobs where someone needs to understand patching, access control, and incident escalation. Because the exam covers escalation, logging, and basic response, it signals that you can contribute to those workflows without needing hand-holding on terminology. Our overview of CCST-C jobs explores the roles in more depth.
On earnings and value, we avoid quoting numbers here because compensation depends heavily on region, employer, and experience. The CCST-C salary guide and the analysis of whether the certification is worth it discuss how to weigh the credential against your own goals.
Preparing: Sequencing the Domains
The most useful planning decision is order. Build from concepts to tools to operations, so each week gives the next one something to stand on. A sample arrangement:
Domain 1: Principles
- Lock in CIA, AAA, and the threat vocabulary first, since every later domain reuses it
- Separate encryption, hashing, and PKI so you can tell them apart under pressure
Domain 2: Network security
- Review protocol weaknesses alongside addressing, NAT, and CIDR
- Walk through DMZ, IDS/IPS, firewall, VPN, and NAC placement
Domain 3: Endpoints
- Run netstat, nslookup, and tcpdump yourself and read real logs
- Cover patching, backups, and compliance-driven policy checks
Domains 4 and 5: Risk and incidents
- Practice ranking risks and distinguishing DRP from BCP
- Map frameworks and the NIST 800-61 lifecycle to sample scenarios, then take timed practice sets
That ordering works because Domain 5 leans on everything before it: you cannot judge when to escalate a suspicious log entry without knowing the threats, protocols, and endpoint behavior it implies. For a fuller plan, see the CCST-C study guide, and for a compact refresher the CCST-C cheat sheet condenses the must-know facts. If you are wondering how demanding the material is before committing, read how hard the CCST-C exam is. When you are ready to test yourself under realistic conditions, the CCST-C practice tests are built around these exact five domains.
