How to Protect Your Laptop From Hacking

Electronic technology is hugely relevant today, so much so that almost everything we use daily, from smartphones to laptops and even home appliances, depends on it. Think about it. You can communicate and share content with family and friends, learn new things online, place orders and have them delivered to your doorstep, and even run complex business operations with ease.


But then, imagine the cost that comes with such convenience. We’ve all heard of the risks associated with sharing personal information over the internet. But sometimes, even the most cautious users get hacked—a prevalent menace known to cost the world $8 trillion annually. Typically, hackers exploit vulnerabilities in electronic devices, such as PCs, through malware, viruses, and trojan horses.


And if you’re unlucky enough to fall victim, your laptop can be used to access stored and shared data or even target other users. So, how do you prevent this from happening?

How To Protect Your Laptop From Hacking

Key Takeaways

  • Invest in reputable antivirus software: Protect your laptop from malware and viruses by using reliable antivirus programs like Norton 360, Bitdefender, or McAfee.
  • Use strong passwords: Prevent brute force attacks by creating strong passwords with a mix of letters, numbers, and special characters, and avoid using the same password for multiple accounts.
  • Avoid connecting to unsecured networks: Be cautious when connecting to open Wi-Fi networks, as they expose your device to security threats. Consider using a VPN service for added protection.
  • Keep your operating system and applications updated: Regularly update your laptop's operating system and installed applications to patch known vulnerabilities and enhance security.
  • Enable two-factor authentication: Add an extra layer of security by enabling two-factor authentication, which requires a code from your phone or email to log in to your account.
  • Limit user account privileges: Use standard user accounts for regular activities and reserve admin accounts for administrative tasks to minimize security risks.
  • Encrypt and back up your data: Protect your sensitive information by encrypting your data and regularly backing it up to external storage or cloud services.
  • Beware of phishing attacks: Stay vigilant against phishing attempts by avoiding clicking on suspicious links or downloading attachments from unknown sources.
  • Increase cybersecurity awareness: Stay informed about cybersecurity threats and best practices through security blogs, industry newsletters, and online courses to better protect yourself against cyber attacks.

Invest in Reputable Antivirus Software

Antivirus software serves as a proactive defense mechanism against malware and viruses, which may infect your laptop and put your data at risk. This tool is a must-have, especially if you actively use the internet or store sensitive information on your device. While Windows comes pre-installed with one, you need to enhance your PC’s protection by getting a reliable third-party program, such as Norton 360, Bitdefender, and McAfee.

However, before you settle for any software, consider factors like:

  • Cost of subscription
  • Compatibility
  • Features offered
  • Malware detection rates
  • Impact on system performance

Many premium programs come with free trial periods, during which you can ascertain the level of protection on offer. There are also free versions that offer essential features but lack additional functionalities. In such cases, understand your security needs before settling for a particular product.


Use Strong Passwords

Brute force attacks are one of the common methods hackers use to gain access to a victim’s devices. The technique involves running automated scripts that cycle through a list of possible password combinations until it finds one that works. About 80% of all data breaches stem from this type of attack, as it has a high success rate.


Your best bet against brute-forcing is to use strong passwords that are more than 12 characters long and include a combination of letters, numbers, and special characters. You can consider using a password manager to generate such unique passwords for all your online accounts. A pro tip: don’t use the same password for two or more accounts to prevent one breach from affecting all.


Avoid Connecting to Unsecured Networks

Finding an open network that allows you to surf the net endlessly, download or upload heavy files, and even stream your favorite videos for free is every user’s dream. But here’s a catch: most such connections are unsecured—meaning they are not encrypted, which exposes your device to threats. And so you know, malware, viruses, and trojan horses spread more quickly over the internet.


Once connected, your laptop may be infected and then accessed without your authorization, which could result in data loss. To prevent this, always be aware of the network you’re on. Avoid connecting to free networks whenever possible, and when you have to, use a VPN service to help hide your online activities from third parties and encrypt your traffic.


Keep Your Laptop’s Operating System and Applications Updated

Microsoft and other developers consistently release updates and patches for their products to fix any known vulnerabilities and address bugs. Unfortunately, many users don’t apply these updates, exposing their devices to hackers. To maintain optimal security, ensure your operating system (OS) is up-to-date. You can do so by:

  • Heading to “Settings” > “Update & Security” and enabling Windows Update.
  • Navigating to “System” > “Advanced System Settings” > “Advanced Tab” and checking for updates under “Automatic Updates.”
  • Using a third-party program such as Patch My PC.

The same applies to applications that run on your device. Check if there are any updates and install them to enhance overall security.


Enable Two-Factor Authentication

Two-factor authentication (2FA) is an additional layer of security that prevents unauthorized access to your laptop, even if a hacker is able to acquire your password. It works by requiring you to enter a code from your phone or email every time you attempt to sign in to your account. So, even if the hacker guesses the correct password, they won’t be able to log in to your device without access to your secondary method.


Limit the Privileges of Your User Account

Your user account determines who has access to specific resources such as folders, processes, and system files, including administrators and standard users. If you are using a standard account, some of these resources are blocked, which makes it difficult for malware and viruses to operate. However, an admin account does the opposite—affording the user unlimited access to everything on the device.


While admin accounts offer convenience, they’re also a liability and must only be used for administrative purposes. So, create standard user accounts for regular activities and restrict admin accounts to only those authorized to perform administrative tasks or in situations when it’s needed.


Encrypt and Back-up Your Data

Data encryption is a security feature that ensures all information on your laptop is securely stored in unreadable formats, making it inaccessible to unauthorized users. This way, if your device is stolen or accessed without authorization, it’s still protected. You can encrypt your data using the built-in tool in the Windows OS or any other third-party product.


It’s also imperative to back up your files to external storage devices such as USB drives or a remote server (cloud) to help you restore them in case of an attack. This also ensures all your data is safe, even if you lose your PC.


Avoid Phishing

Phishing attacks are a big threat to users, with many of them aimed at tricking you to install malicious programs on your device. A typical phishing attack begins with an email or text that claims to come from a reputable organization or person. However, once you click on a link or download a file attached to the message, it allows the hacker to install malware that helps them gain control of your device and access your sensitive information.


Don’t fall for this technique—only download attachments from trusted sources, and never click on links in emails that you’re not certain of. If in doubt, run a background check on the sender on Nuwber.


Increase Your Cybersecurity Awareness

Staying updated on the latest security news is a sure way to understand the risks associated with technology use, which is a critical step in enhancing your cybersecurity. Make it a habit to read security blogs, subscribe to industry newsletters, or follow reputable cybersecurity experts on social media to be in the know. You can also take online courses on the subject.


Conclusion

Cyber attacks are on the rise, and the only way to survive is by taking your security seriously and understanding the risks. So, consider the above tips when enhancing your laptop’s protection to ensure the information you hold is secure.
