Cybercentry Security Onion: A Simple Guide for Cybercentry Community Members
Share
What is the Cybercentry Security Onion?
The Cybercentry Security Onion is a layered approach to protect Cybercentry Community Members. Just like an onion, which has multiple layers, this model safeguards your assets and information through various security levels.
The Cybercentry community thrives on knowledge sharing, and this guide builds on that principle by encouraging members to take simple, consistent steps to improve their security. Each layer focuses on practical tips, ensuring that members can protect themselves effectively.
What is the OSI Model?
The OSI (Open Systems Interconnection) Model is a framework that explains how computers and networks communicate. It is divided into seven layers, each with specific tasks to ensure smooth communication. By applying security measures to each layer, you create a strong defence for your cryptocurrency trading.
Think of this as your personal crypto security checklist, building layer by layer for maximum protection.
The Cybercentry Security Onion with the Seven Layers of the OSI Model
1. Physical Layer – Protecting Your Devices
What It Is: This is about securing the hardware you use, like your computer, smartphone, or hardware wallets.
How to Stay Safe:
• Use a hardware wallet (e.g., Ledger or Trezor) to store private keys offline.
• Lock your devices in a secure place when not in use, such as a safe.
• Avoid buying second-hand devices unless you trust the source.
2. Data Link Layer – Securing Your Local Network
What It Is: This layer secures your home internet connection.
How to Stay Safe:
• Set a strong Wi-Fi password using the Three Random Words method. For example: "applenemobiro" is easy to remember, but it is random enough to stop attackers from guessing it.
• Ensure your router is using WPA3 encryption (check your router settings for this option).
• Regularly update your router’s firmware to fix security issues.
3. Network Layer – Safe Internet Browsing
What It Is: This layer protects your activity when browsing online.
How to Stay Safe:
• Use a VPN (e.g., ProtonVPN) to encrypt your internet traffic and hide your location.
• Avoid trading on public Wi-Fi unless you are using a VPN for added security.
• Activate your device software firewall to block unwanted access.
4. Transport Layer – Securing Data in Transit
What It Is: This layer ensures that your data is safe as it moves across the internet.
How to Stay Safe:
• Only use websites that start with https:// (look for the padlock icon in your browser).
• Avoid clicking on links in unsolicited emails or messages.
• Install browser extensions like uBlock Origin to block harmful websites.
5. Session Layer – Keeping Your Accounts Secure
What It Is: This layer manages your sessions when logging into platforms.
How to Stay Safe:
• Use Two-Factor Authentication (2FA) for all your accounts to add an extra layer of security.
• Create strong, unique passwords for each account and store them in a password manager like Dashlane, LastPass, or 1Password. For example: With a password manager, you can securely store complex passwords like "Gy#3k@zP&9" or easily remember strong ones like "applenemobiro"
• Regularly review account activity to detect unauthorised access.
6. Presentation Layer – Ensuring Accurate Information
What It Is: This layer ensures that the information displayed to you is reliable.
How to Stay Safe:
• Double-check wallet addresses before sending funds – scammers can manipulate clipboard data.
• Use trusted blockchain explorers (e.g., Blockscout) to verify transactions.
• Only use official versions of apps downloaded from trusted sources.
7. Application Layer – Protecting Your Apps and Platforms
What It Is: This layer is where you interact with trading platforms and wallets.
How to Stay Safe:
• Use smart wallets that provide alerts for suspicious activity and verify transactions.
• Download apps only from official app stores or websites.
• Be wary of phishing attempts – always check URLs and avoid clicking on links in emails.
Core Layers: Always Be Ready
Incident Response – Knowing What to Do
What It Is: This is your plan for when things go wrong.
How to Stay Safe:
• Back up your wallet’s seed phrase offline in a secure, fireproof location.
• Report scams to the platform or relevant authorities.
• Keep a list of emergency contacts for your wallets and exchanges.
Threat Intelligence – Staying Informed
What It Is: Keeping up to date with the latest scams and threats.
How to Stay Safe:
• Regularly update your software, apps, and tools to patch vulnerabilities.
• View trusted resources like the Solidity Scan for cryptocurrency security scores.
• Set Notifications to ‘All Messages’ for the report-scammers channel to share and learn about emerging risks.
Why Use the Cybercentry Security Onion?
Each layer of the OSI Model adds protection to your cryptocurrency trading. Start with the basics:
• Create strong passwords using the Three Random Words method, like "applenemobiro" or use a password manager.
• Enable 2FA for your accounts.
• Use a hardware wallet for long-term storage.
• As you add more layers, your defences become stronger, making it harder for attackers to breach.
Remember: Security is an ongoing process. Small, consistent improvements will keep you ahead of the threats.
