Practical guides to protect yourself and your organization online
Preventing Data Breaches
A data breach is when sensitive information is accessed without authorization. Here is how to protect yourself and your organization.
Use Strong, Unique Passwords
Never reuse passwords across accounts. Use a password manager to generate and store complex passwords with at least 16 characters, mixing letters, numbers, and symbols.
Enable Multi-Factor Authentication (MFA)
Always enable MFA on every account that supports it. This adds a second layer of verification beyond your password, making unauthorized access significantly harder.
Keep Software Updated
Outdated software contains known vulnerabilities. Enable automatic updates on your operating system, browsers, and all applications to patch security holes promptly.
Be Cautious with Email Links
Phishing emails are the #1 cause of data breaches. Never click suspicious links or download unexpected attachments. Verify the sender address and hover over links before clicking.
Monitor Your Accounts
Regularly review bank statements, account activity, and set up alerts for unusual login attempts. Early detection limits the damage of a breach.
Limit Data Sharing
Only provide personal information when absolutely necessary. The less data you share online, the less there is to steal in a breach.
Preventing Data Loss
Data loss can happen due to hardware failure, accidental deletion, cyberattacks, or natural disasters. Protect your valuable data with these practices.
Follow the 3-2-1 Backup Rule
Keep 3 copies of your data, on 2 different types of storage media, with 1 copy stored offsite or in the cloud. This ensures recovery even if primary storage fails.
Use Cloud Storage
Sync important files to cloud services like Google Drive, OneDrive, or Dropbox. Cloud providers replicate your data across multiple data centers for redundancy.
Automate Backups
Set up automatic backups so you never forget. Schedule regular backups of your critical files, databases, and system configurations.
Encrypt Sensitive Data
Use encryption for files containing personal, financial, or proprietary information. Even if data is stolen, encryption renders it unreadable without the key.
Test Your Backups
A backup is only useful if you can restore from it. Periodically test your backup restoration process to confirm data integrity and recovery time.
Use Version Control
For important documents and code, use version control systems. This allows you to roll back to previous versions if files become corrupted or accidentally modified.
Online Etiquette
Good digital etiquette creates a respectful and professional online environment. Follow these guidelines in all online interactions.
Think Before You Post
Everything you post online can be permanent. Once something is shared, you lose control over who sees it and how it is used. Pause and consider consequences before posting.
Respect Privacy
Never share someone else personal information, photos, or private conversations without their explicit consent. Respect digital boundaries just as you would in person.
Communicate Professionally
Use proper grammar, avoid ALL CAPS (which reads as shouting), and be mindful of tone in emails and messages. Professional communication builds trust and credibility.
Do Not Feed the Trolls
Responding to provocateurs online only escalates conflict. Disengage from toxic conversations, use block/mute features, and report abusive behavior.
Credit Original Creators
When sharing content, always attribute it to the original author or creator. Plagiarism and content theft are taken seriously online and can damage your reputation.
Be Inclusive
Use accessible language, avoid jargon when talking to general audiences, and be mindful of cultural differences in global online communities.
Digital Hygiene
Just like personal hygiene keeps you healthy, digital hygiene keeps your devices, accounts, and data secure and running smoothly.
Review App Permissions
Regularly audit which apps have access to your camera, microphone, location, and contacts. Revoke permissions for apps that no longer need them.
Clear Browser Data Regularly
Clear cookies, cache, and browsing history periodically. This prevents tracking, frees up storage, and reduces the risk of session hijacking.
Log Out of Unused Sessions
Log out of accounts on devices you no longer use, shared computers, or old browsers. Active sessions are entry points for unauthorized access.
Use Secure Wi-Fi Networks
Avoid conducting sensitive transactions on public Wi-Fi. If you must use public networks, always use a VPN to encrypt your traffic.
Keep Devices Physically Secure
Never leave devices unattended in public places. Use screen locks, biometric authentication, and enable remote wipe capabilities in case of theft.
Unsubscribe and Clean Up
Unsubscribe from newsletters you no longer read, delete unused accounts, and remove old apps. A smaller digital footprint means less attack surface.
