Technical and Soft Skills for Cybersecurity Roles

#### Technical Skills
Technical skills form the core of cybersecurity operations, enabling professionals to detect, analyze, and neutralize threats. Mastery of these skills is role-dependent but often overlaps across domains.

• Networking Fundamentals

  Understanding TCP/IP, firewalls, VPNs, and subnetting is critical for monitoring traffic, identifying anomalies, and configuring secure networks. For example, a SOC Analyst uses Wireshark to inspect packets for malicious payloads, while a Security Architect designs network segmentation policies to limit lateral movement.

• Operating System Hardening

  Proficiency in securing Windows (e.g., Group Policy, Windows Defender), Linux (e.g., SELinux, AppArmor), and cloud platforms (e.g., AWS IAM, Azure AD) reduces attack surfaces. Ethical hackers exploit misconfigurations (e.g., default credentials) to demonstrate vulnerabilities, while architects implement least-privilege access models.

• Scripting and Automation (Python, Bash, PowerShell)

  Automation streamlines repetitive tasks such as log analysis, vulnerability scanning, or incident response. For instance, a SOC Analyst might use Python to parse SIEM logs (e.g., Splunk, ELK Stack) for patterns, while a Security Architect automates compliance checks with Ansible or Terraform.

• Encryption and Cryptography

  Knowledge of symmetric (AES) and asymmetric (RSA) encryption, hashing (SHA-256), and PKI (Public Key Infrastructure) is essential for securing data in transit and at rest. Ethical hackers crack weak encryption (e.g., WEP vs. WPA3) to test defenses, while architects design TLS 1.3 implementations for web applications.

• Threat Intelligence and Analysis

  Familiarity with MITRE ATT&CK, STIX/TAXII, and OSINT (Open-Source Intelligence) frameworks helps professionals map adversary tactics. SOC teams use MITRE ATT&CK to correlate indicators of compromise (IoCs), while threat hunters proactively search for APT (Advanced Persistent Threat) activity.

• Cloud Security (AWS, Azure, GCP)

  Cloud adoption has shifted security focus to shared responsibility models, IAM policies, and container
