What Is ISC2 Certified in Cybersecurity (CC) Certification ?
ISC2 Certified in Cybersecurity (CC) certification is designed for people who are new to the field. This is a cybersecurity certification for beginners. This was done because more and more people are joining the cybersecurity workforce without having direct IT experience. The ISC2 Certified in Cybersecurity (CC) certification gives employers trust that you understand the right technological concepts and have proved that you can learn on the job.
Understanding Security Principles (Domain 1 Overview)
Domain 1 of ISC2 Certified in Cybersecurity may appear difficult, but it is based on simple, repeatable ideas. Whether you’re studying for the ISC2 Certified in Cybersecurity (CC) exam or just want to know what all the acronyms mean, this guide makes it easy to understand. Fol technical terms will be explained in this chapter of isc2 cc certification:-
- Information security, IT security, and cybersecurity
- The CIA Triad vs. DAD
- IAAA: The Four-Step Access Checkpoint
- Access Control Models
- Privacy and PII
- Risk Management.
- Security Controls
- Governance vs. Management.
- Policy, Standard, Guideline, Procedure
- Law and Ethics in Security
- Ethics (ISC2 Code)
InfoSec, IT Security, and Cybersecurity
What’s what?
- 🛡️ InfoSec protects all information physical and digital.
- 💾 IT Security protects the systems that store and move that information.
- 🌐 Cybersecurity guards internet connected systems against online threats.
Think of it like layers of protection:
- ☂️ InfoSec is the umbrella
- 🧥 IT Security is the jacket
- 🌧️ Cybersecurity is the outer shell facing the storm
The CIA Triad vs. DAD
Good guys:
- 🔒 Confidentiality – Only authorized users access data
- 🧮 Integrity – Data stays accurate and untampered
- 🕐 Availability – Data and systems are accessible when needed
Bad guys (DAD):
- 💥 Disclosure – Sensitive info gets leaked
- ✏️ Alteration – Data is changed without permission
- 🔥 Destruction – Systems or data are wiped or crashed
Example:
Online banking should encrypt statements (C), ensure transactions aren’t tampered (I), and stay up on payday (A).
IAAA: The Four-Step Access Checkpoint
Every secure system follows this access flow:
1. 👤 Identification – “I am Amina.”
2. ✅ Authentication – “Prove it” (password, MFA, biometrics)
3. 🧾 Authorization – “What can I access?”
4. 📜 Accountability – “Log everything so we know who did what”
Rule of thumb:
No shared accounts. No excuses. 👎
Access Control Models
Choose the access model that fits the environment:
- 🧍♀️ DAC (Discretionary) – User controls access (e.g., home folder)
- 🛡️ MAC (Mandatory) – System enforces labels (e.g., “Top Secret”)
- 👔 RBAC (Role-Based) – Based on job title or department
- 📍 ABAC (Attribute-Based) – Based on context like time, location, device
Scenario:
A payroll analyst (RBAC) can access data only during business hours from HQ (ABAC), but can’t see executive bonuses (MAC).
Privacy and PII
PII = Personally Identifiable Information 🕵
Examples: name, address, email, phone number, IP address
- US: Patchwork of laws (HIPAA, state breach laws)
- EU (GDPR): Strict, global, and non-negotiable
GDPR Rules to Remember:
- 72-hour breach notification
- Right to access and delete data
- Privacy by design required
- Huge fines if you ignore it 💸
Risk Management
Three key ingredients:
- 🎯 Threat – Something that can go wrong
- 🧱 Vulnerability – A weakness that can be exploited
- 🚨 Impact – How bad it would be if it happens
Security Controls: Build Layers
Three categories:
- 🧠 Administrative – Policies, training, HR procedures
- 💻 Technical – Firewalls, encryption, MFA, logging
- 🏢 Physical – Locks, cameras, gates, guards
Six control types:
- 🛑 Preventive
- 👁️ Detective
- 🛠️ Corrective
- 🔄 Recovery
- ⚠️ Deterrent
- 🧩 Compensating
Example:
- Security signage (⚠️ Deterrent)
- Firewall (🛑 Preventive)
- Backup system (🔄 Recovery)
Governance vs. Management
- 🏛️ Governance: Sets goals, risk tolerance, and oversight (board/C-suite)
- 🧑💼 Management: Builds and runs the tools and processes to meet those goals
Think of it like a ship:
- Governance sets the course 🧭
- Management steers the ship and monitors the radar 🛳️
Policy, Standard, Guideline, Procedure
Get these right and everyone works smarter:
- 📋 Policy – The mandatory high-level rule
- 📐 Standard – The required specifics
- 🧾 Guideline – The recommended best practice
- 🧪 Procedure – The step-by-step “how-to”
Quick Tip:
- Policy says “Encrypt data”
- Standard says “Use AES-256”
- Guideline says “Use 4-word passphrases”
- Procedure says “Follow these steps to enable encryption on your device”
Law and Ethics in Security
Legal obligations:
- 🏥 HIPAA – Protects health data
- 🧑💻 CFAA – US anti-hacking law
- 💳 PCI-DSS – Payment card protection (contractual)
- 🌍 GDPR – Global privacy law with strict rules
Ethics (ISC2 Code):
- 🌍 Protect society and public trust
- 💬 Be honest and responsible
- 🧠 Stay competent and keep learning
- 📈 Elevate the profession
Real-world example:
You find a password on a sticky note. Don’t use it.
Report it. Educate. Enable MFA.
