What is Cybersecurity?
Cybersecurity is all about keeping our computers and data safe from the not so good people online. Cybersecurity is the same as having a bodyguard for your digital self. Just like we lock the doors of our homes to keep thieves out, cyber security locks the doors of our digital world. The CIA triad represents the three principles of cyber security; confidentiality, integrity, and availability.
These three principles work together to protect your information. Confidentiality means that only those who are allowed can view your information. Integrity means that your data means the data is correct and not altered. Finally, availability means you are able to access your information at will.
Common Cyber Threats You Should Know
1. Phishing Attacks
Phishing is like a fake email that looks real. Bad people send these emails to trick you. They might say they are from your bank or a website you use. They want you to give them your password or credit card number.
2. Malware
Malware is bad software that gets into your computer. It can steal your files or make your computer slow. Viruses, worms, and trojans are all types of malware.
3. Ransomware
This is very dangerous malware. It locks all your files and asks for money to unlock them. Many businesses have lost millions of dollars because of ransomware.
4. Social Engineering
This is when bad people trick you by pretending to be someone else. They might call you and say they work for your internet company. Then they ask for your personal information.
Types of Cybersecurity
Type | What It Protects | Example |
Network Security | Internet connections | Firewalls, VPN |
Information Security | Data and files | Encryption, Passwords |
Application Security | Software and apps | Updates, Secure coding |
Endpoint Security | Devices | Antivirus, Device management |
Cloud Security | Online storage | Access controls, Encryption |
How to Protect Yourself Online
Strong Passwords
When creating passwords, make them hard to guess. Always try to put a mixture of big, small letters, numbers and symbols. Do not ever use the same passwords for everything.
Good password: Sunshine!River_92BlueTree
Bad password: password123
Two-Factor Authentication
This adds extra security to your accounts. Even if someone knows your password, they need a second thing to get in. This could be a code sent to your phone.
Keep Software Updated
Updates fix security problems. Always install updates for your computer, phone, and apps. Turn on automatic updates if you can.
Be Careful with Emails
Do not click on links or download files from emails you do not trust. If an email looks suspicious, delete it. When in doubt, ask someone for help.
Use Antivirus Software
Good antivirus software can find and remove malware from your computer. Keep it updated and run scans regularly.

Creating a Personal Security Plan
Every person needs a security plan.Here is how to create one:
Step 1: List Your Devices Write down a list of all your devices. You should include computers, phones, tablets and smart home devices.
Step 2: List Your Accounts Write down a list of all of your online accounts: your email, social media accounts, banking accounts, shopping sites, and anything else.
Step 3: Secure Your Stuff Use strong passwords, two-factor authentication, and security software on all accounts and devices.
Step 4: Make Backups Copy and save your important stuff. If you lost everything but had a backup, you wouldn’t lose everything.
Step 5: Review Every Few Months Review your security regularly, at least every few months. Whenever possible, change your passwords, update your software, and delete accounts you no longer use.
Common Mistakes to Avoid
Using Weak Passwords
Still using passwords like “123456” or “password”? Asking to get hacked. Use strong and unique passwords without reusing them.
Clicking on Everything
Do not click on links or download files without thinking. Many attacks start with a single click on the wrong thing.
Ignoring Updates
Software rarely works perfectly. When companies release software updates it’s to fix security holes. If you don’t update they can gain access.
Sharing Too Much Online
Don’t share too much online or any social media platform. If you are not careful, criminals can use this information to attack you.
Not Having Backups
If some disasters happen and you lose all of your data with no backups, you might have just lost it all forever. Always keep copies of your important things, at a minimum once a month.
The Future of Cybersecurity
Technology is always evolving which means that cybersecurity is too. Many new threats emerge on a daily basis. There will always be a demand for people who know and understand security threats.
Artificial intelligence is changing the landscape of how we proactively fight against cybercriminals. AI has made it possible to detect threats faster than humans can.
Cybercriminals are taking advantage of this growing technology, too. They are leveraging AI technology to build better attacks on the users of the technological devices that they steal from.
The Internet of Things (IoT) grows by connecting more and more devices to the internet. Your car, refrigerator, doorbell, etc. may all be on the internet at the same time, which always creates a possibility for a fault of not protecting your data.
Conclusion
Cyber safety and security is not just for computer experts anymore; we all must have an understanding of safety and security to stay secure online. Start with simple things like strong passwords, or being careful about emails.
