PCES-30-01 Exam Topics and Domains
PCES-30-01 is organized into 4 weighted domains.
Security Essentials
The CIA Triad and Beyond
- Explain the concepts of Confidentiality, Integrity, and Availability
- Evaluate trade-offs between strong Security and system Usability in real-world scenarios
- Explain how Authenticity and Accountability extend the CIA model
- Provide examples of accountability measures and authenticity in action
IT Threats and Risks
- Identify and classify threats and risks to IT systems (malware types, phishing/social engineering, DoS/DDoS)
- Differentiate malware types: viruses, worms, trojans, ransomware, spyware
- Explain motivations behind threat actors (financial gain, disruption, espionage)
- Describe basic protection measures (encryption, antivirus, MFA, backups, layered defenses)
Consequences of Data Loss, Theft, or Modification
- Explain potential impacts of losing critical information (financial, operational, HIPAA/GDPR)
- Describe security and reputational consequences of data theft (IP theft, PII exposure)
- Describe consequences of manipulated or altered data (safety, operational, reputational)
Losses from System Unavailability
- Analyze operational, financial, and safety impacts of system downtime in critical environments
- Explain lost sales/revenue, emergency fix costs, delays in critical services, compliance issues
IT Systems Security
Security Principles and Practices
- Explain why security is a continuous process (monitoring, updating, patching)
- Implement technical safeguards: firewalls, IDS, IPS, VPNs
- Apply organizational safeguards: least privilege, device restrictions, limited trust, anonymization, security training, prod/test isolation
- Apply secure development practices: peer reviews, early security requirements, log anonymization
System Hardening
- Implement a system hardening process (when/how often
- remove unnecessary services, apply updates, configure secure settings)
Network Security Basics
- Explain roles of ports, protocols, and services (HTTP, HTTPS, SSH, FTP
- open port vulnerabilities)
- Configure basic network security settings (disable unused services/ports, segmentation, isolation)
Authentication, Authorization, and Access Control
- Differentiate authentication (verify identity) and authorization (grant permissions)
- Configure secure password-based authentication (policies: expiry, history, complexity)
- Describe components and benefits of multi-factor authentication (SMS, authenticator apps, hardware tokens)
Cloud and Remote Security Basics
- Identify security risks of cloud storage (misconfigured buckets, shared responsibility model)
- Apply best practices for securing SaaS apps and remote access (VPNs, device hardening for remote workers)
Python for Security Operations
Using Python for Ethical Security Assessments
- Conduct authorized security assessments (written permission, port scans via socket/python-nmap, identify open ports/services)
- Perform basic vulnerability checks (outdated software, weak/default passwords in test environments)
- Gather information legally/ethically (WHOIS queries, banner grabbing)
Using Python for Defensive Security
- Detect outdated/insecure websites (check SSL/TLS validity and expiry with ssl and socket
- alert on near-expiry)
- Monitor OS processes for suspicious activity with psutil (CPU, memory, network patterns)
- Automate system security checks and responses (firewall status, pending updates, notify admins, restart services)
- Execute OS-level commands with subprocess (antivirus scans, log archiving/cleanup)
Event Correlation
- Correlate logs from multiple sources (firewall, server, authentication logs
- failed login patterns, correlated alerts)
Security Reporting
- Generate structured reports (export to CSV, JSON, PDF
- include timestamps, IPs, threat types
- visual summaries)
- Document and report test results (actionable recommendations from automated outputs)
Scheduling and Orchestration
- Schedule recurring scans/checks (cron, Task Scheduler, APScheduler)
- Automate backups and verify them (check completion, validate integrity and recovery)
- Chain security tasks (checks, backups, cleanups, reporting in sequence)
Secure Development & Implementation in Python
Secure Coding Practices
- Perform static analysis with linters (pylint, flake8)
- Validate and sanitize user input (parameterized queries against SQL injection, block XSS by escaping HTML)
- Apply output encoding and escaping (HTML, XML, JSON)
- Implement secure file and exception handling (sanitize file paths against directory traversal, hide tracebacks/paths)
- Manage sensitive configuration data securely (env variables for passwords/API keys, avoid committing secrets)
Using Security Libraries and Tools
- Encrypt and decrypt data with cryptography (Fernet keys, encrypt/decrypt text or files)
- Use paramiko for secure communications (SSH connections, SFTP transfers)
- Handle documents/files securely (PyPDF2 password protection, python-docx and openpyxl to sanitize
- detect malicious macros)
Data Integrity and Authenticity
- Verify file integrity with hashes (SHA-256+
- why MD4/MD5 are insecure due to collisions)
- Validate downloaded files with checksums (compare computed vs published values)
