In today’s digital world, our personal information is more vulnerable than ever. From social security numbers and addresses to credit card details, hackers are constantly seeking to gain access to our sensitive data. With just a few key pieces of information, a malicious actor can impersonate you, gain control of your identity, and cause significant harm.
However, you can take control of your digital safety. This article will provide you with essential steps to protect yourself and your family from these threats. By making some small, mindful changes to your daily habits, you can significantly reduce your risk of being hacked.
Safeguarding Your Mobile Devices
Your smartphone is a gateway to your personal life. Here’s how you can make it more secure.
The Dangers of Unsecured Wi-Fi and Bluetooth
One of the easiest ways for hackers to gain access to your phone is through your Wi-Fi and Bluetooth connections. Keeping these features on all the time gives hackers easy access.
When your Wi-Fi and Bluetooth are constantly active, hackers can see a list of the networks you’ve connected to in the past. They can then create a fake network with the same name, tricking your phone into automatically connecting to their device.
Once your phone is connected to the hacker’s device, they can:
- Access your stored data and spy on all the information you input.
- Install malware on your phone, making it difficult to trace their presence.
Actionable Advice: To protect your phone, you should always turn off your Bluetooth and Wi-Fi when you are not actively using them.
Strengthening Your Passwords and Accounts
Passwords are your first line of defense. Don’t make it easy for hackers to get past them.
The Importance of Unique Passwords
Never use the same password for multiple accounts. Using one password acts like a master key that can unlock your entire digital life. Once a hacker gains access to one account, they can try that same password on all your other websites, including banking, social media, and email.
- Use Unique Passwords: Each of your accounts should have its own, unique password.
- Change Passwords Regularly: It’s a good practice to change your passwords at least once a year to keep your accounts secure.
Embrace Two-Factor Authentication (2FA)
A two-step authentication process, also known as Two-Factor Authentication (2FA), provides a critical layer of security. This requires you to verify your identity with a second piece of information in addition to your password.
Many popular services, including social media sites and email providers, now offer this feature. When you log in from a new device, a temporary code is sent to your registered phone number or email address. While a hacker might get hold of your password, it’s highly unlikely they will also have access to your phone’s messages to get the verification code.
Important Tip: If you change your email or phone number, be sure to update this information with your online accounts immediately to avoid being locked out.
Using Strong Passphrases and Password Managers
For websites that contain sensitive data, like your email or bank account, use a long and unique passphrase. An example of a strong passphrase is: +HISpl@tinumDr@gonBreathsfire.
For other, less sensitive websites, you can use a password manager to store your passwords securely. Password managers like Password Safe and LastPass encrypt all the passwords stored on your device, ensuring they are protected.
Securing Your Network and Browsing Habits
Your internet connection and browsing habits can also open the door to hackers.
The Necessity of HTTPS
When browsing the web, always make sure you are using HTTPS (Hypertext Transfer Protocol Secure). If a website’s address bar shows “HTTP” without the “s,” it means the connection is not encrypted. This allows anyone to view the information you are transmitting or receiving.
Tool Recommendation: The program HTTPS Everywhere is a valuable tool that automatically encrypts all information sent between your browser and the websites you visit.
Protecting Your Home Wi-Fi
Your home Wi-Fi network is a potential entry point for hackers. Here’s how to secure it:
- Change the Default Password: Your router comes with a default password on a sticker. You must change it! Default passwords are too easy for hackers to guess.
- Choose WPA-2 Encryption: When setting up your Wi-Fi, always choose WPA-2 for the security encryption type.
- Avoid WEP and WPA: These older encryption standards have known flaws that can give up your network password in seconds.
Some routers offer the option to hide the SSID (Service Set Identifier), which makes your Wi-Fi network invisible to others. While this sounds secure, it can force your devices to constantly search for the network, potentially making them vulnerable to connecting to a strange or fake network during the scan.
Protecting Your Devices and Software
Software security is just as important as network security.
Understanding IoT and Smart Devices
Modern homes are filled with Internet of Things (IoT) devices, such as smart fridges, ovens, and baby monitors. While these offer convenience, the companies that create them are still working out the kinks (flaws or bugs) in their security. A notable example is when a hacker hijacked a baby monitor and spoke foul-mouthed things to a child.
As security expert Stanislav says, even if you are told a device is secure, it might not be. Ultimately, the security of your devices is your responsibility.
Keeping Your Computer Secure
- Firewall: Always keep your firewall turned on. This program helps block unauthorized access to your computer. Most operating systems come with a built-in firewall, but you can also purchase a third-party program.
- Antivirus Software: Keep your antivirus software updated. These programs are designed to prevent malicious software from embedding itself in your computer. When a threat like a virus or a worm is detected, it works to remove it.
- Antispyware Technology: Just as its name suggests, antispyware prevents malicious software that spies on your computer activity. Some spyware collects your data without consent and even produces unwanted pop-up ads. Ensure this technology is also kept up to date.
- Regular System Updates: Keeping your operating system and software updated is crucial. Each new update includes fixes for security flaws discovered since the last version. By ignoring updates, you give hackers an easier way to access your machine.
Email and Phishing Scams
Your email is a common vector for hacker attacks. Never open an email from someone you do not know. These emails can contain malicious code or viruses that can infect your computer and allow a hacker to gain access to your machine and data.
The Final Step: Turn It Off
When you are not using your computer, turn it off. While it may be convenient to leave your computer on for quick access, spyware and viruses can still access your machine and allow hackers to get in without you knowing. Powering down your device cuts off this potential entry point.
