Cybersecurity tips for students: How to protect your data and devices

What is cybersecurity for students?

Cybersecurity for students refers to the habits you should practice to protect your digital devices, personal information, and school or college accounts from hackers, scams, and malware.

Why is cybersecurity important for students? 

Cybersecurity is important if you are a student because it protects you from identity theft, data loss, and device damage while you study, socialize, and attend classes online.

College students are prime targets for cybercriminals because of their frequent use of online spaces and multiple devices, yet many underestimate the threat.

Key cybersecurity risks for students include:

• Phishing: Phishing is when scammers use personalized emails or messages to impersonate university staff and encourage you to click unsafe links. These attacks are often highly sophisticated and hard to spot, but they can lead to the theft of your login credentials, bank details, or Social Security number.
• Social engineering: Social engineering attacks use fraudulent emails or messages designed to trick you into revealing confidential information. They usually offer something like a free download or gift card. Using social engineering, attackers can exploit your trust, fear, or curiosity to get you to send money or reveal login credentials.
• Credential theft: If you reuse the same passwords across your academic and personal accounts, a single breach can let cybercriminals access your other accounts — including ones storing sensitive research — or sell your details on the dark web. This personal information can be used to illegally apply for, receive, or take over student loans or financial aid. 
• Malicious downloads: Downloading EdTech software, academic materials, or plugins from untrusted sources can infect your devices with malware that steals sensitive data, spies on your activity, or hijacks system resources.
• Ransomware: Cyberattackers often target campus networks to lock systems and steal sensitive data. While your school or institution should manage its overall network defense, it’s important to be aware of the personal risks of ransomware — malicious software designed to lock you out of your computer or encrypt your files. 
• Job scams: Online fraudsters can easily target students with fake jobs or financial aid offers. These offers may seem legitimate, but many will go on to demand upfront payment or “investment,” or manipulate you into handing over your bank or Social Security details.

Using a VPN in school or university can help neutralize some of these threats, especially when connecting to public Wi-Fi in libraries and cafes. A VPN prevents hackers from intercepting your passwords, data, and personal emails and can also reduce the risk of network snooping.

Cybersecurity tips for students

Using a VPN is a strong defense against cyber threats, but it works best alongside other habits. Many students and young people are intimidated by the idea of implementing cybersecurity measures because they think it’s too hard, or they worry they’ll get it wrong and put their much-needed laptops, phones, and tablets at risk.

Lots of information online tells you what you need to know about cybersecurity, but it can be overwhelming and difficult to know which sources to trust.

Use public and campus Wi-Fi carefully

Staying safe on public Wi-Fi takes a mix of technical defenses and safe browsing habits. Yes, you do need a VPN, especially when it comes to protecting your device on public Wi-Fi, like in a coffee shop or library.

Campus Wi-Fi can seem safer, but it is still vulnerable to cyber threats. For example, evil twin cyberattacks involve hackers setting up fake, malicious Wi-Fi hotspots that mimic the names of legitimate university networks. If you connect to one of these networks, a hacker can intercept your login details or steal your personal data.

As well as using a VPN, disable automatic connections so your device doesn't automatically join a network set up by a hacker. You should also turn off file sharing and AirDrop while on public Wi-Fi, to stop attackers from sending malicious files to your devices.

Create strong passwords and use a password manager

Strong passwords play a big role in protecting your online accounts and data. You’ve probably heard that you should never reuse the same password across multiple accounts, but the complete online safety advice goes a lot further.

A longer password is better because one that’s 16 to 64 characters is a lot harder to crack than a shorter one. Avoid replacing letters with numbers (bots can easily spot this trick) and use a mix of upper and lowercase letters. 

Always create a unique password when setting up a new account and use different passwords for different sites and apps. You can use a password manager to store them securely so you don't have to remember them. 

Use multi-factor authentication

Multi-factor authentication (MFA) is a security process that requires two or more different types of verification — such as a password, fingerprint, or one-time code — to access your account.

You may enable MFA on Google or your email inbox, for example. Sometimes after you enter your password, the app or service asks you to authenticate your login with a fingerprint or a one-time passcode. You may also be asked to answer a security question or use an authenticator app.

Using two or more authentication methods may seem like a pain, but it significantly reduces the risk of your account being hacked or compromised. 

Check your social media privacy settings

When you’re browsing social media, cybersecurity is probably the last thing on your mind, but apps like Instagram, TikTok, and Snapchat can also be vulnerable to scams, identity theft, and malware distribution.

So how can you protect yourself on social networking sites and apps? First, be careful what you post. Attackers can use information from your profile — such as your location, recent life events, or interests — to craft convincing phishing emails or scam messages. Online dating scams are rife, and scammers can easily manipulate you into oversharing information, sending money, or clicking malicious links if you are too trusting.

Posting seemingly innocuous details like your pet’s name or date of birth can also provide hackers with the exact answers needed to crack your security questions and hijack your personal or financial accounts. 

To protect yourself on social media, set your account to private, never click on unfamiliar links, and be wary of follow requests or DMs from people you don't know.

Use secure cloud storage for assignments

When storing your assignments, use secure cloud storage that puts privacy first and protect your account with a hard-to-guess password and multi-factor authentication. 

Not all encryption is equal, so it’s best practice to use cloud services that advertise “zero-knowledge” or end-to-end encryption to protect your coursework. These providers don't hold a master key to your files. End-to-end encryption is different from standard encryption, where the provider holds the decryption keys and could technically access your data. 

Examples of standard encryption cloud storage providers include Google Drive and Microsoft OneDrive. If you're looking for zero-knowledge encryption, NordLocker offers secure cloud storage where only you can access your files.

Be aware when using online banking services

Banks are often associated with high security, but careless use can still be risky. Cybercriminals can create highly convincing scam emails and texts that mimic your bank to trick you into revealing login information or one-time passwords, while hackers can intercept the data traffic between your device and your bank’s servers on unsecured public networks.

When out and about, use a VPN for online banking and avoid logging into your banking app on public Wi-Fi networks. Always log out when you’re finished and use a strong password and MFA to protect your account. Never give your online login details to anyone over the phone — legitimate banks will never ask you to share this information outright.

Pay attention to your smart devices

As a student, you probably spend a lot of time in public spaces like libraries, coffee shops, and around campus — and you never know who’s snooping. 

Although you may trust those around you, it’s best to err on the side of caution when it comes to your smart devices. Never leave your mobile phone or laptop unattended, and ensure you lock the screen with a strong passcode or biometrics.

To ensure your device stays secure, you should also keep software up to date because out-of-date apps and systems can leave known vulnerabilities unpatched. Delete apps you're not using and share files responsibly with your peers — restrict link access on documents, revoke access to group folders after use, and use zero-knowledge encryption where possible.

You may have other smart devices in your room, such as a smart speaker, lighting, or streaming devices. Student housing is particularly vulnerable to IoT attacks for this reason. Networks become congested, and cybercriminals can easily scan for unpatched or unsecured hardware to infiltrate. 

To reduce the risks, never connect these devices to the same Wi-Fi network as your laptop or your phone. Instead, use your router's guest network feature to isolate smart devices and change the admin password of every new device immediately during setup. Turn off universal plug and play (UPnP) in your router settings to prevent smart devices from bypassing firewall rules.

Secure your data while studying abroad

Traveling abroad poses even more complex security threats. Staying safe requires protecting your devices from insecure networks and preventing physical theft.

To protect your devices when traveling or living in a foreign country, use a trusted VPN, back up your data, and delete sensitive information stored in your devices (like passwords saved in a notes app). 

You should also turn off auto-connect settings to prevent your device from silently connecting to malicious hotspots disguised as public networks. 

Be attentive when using AI

Using AI comes with risks, even for students who use it often. First, don’t rely on AI tools for studying or essay writing, because even the most sophisticated chatbots get details wrong. Double-check information in AI overviews and chatbot responses and verify your sources. 

Before pasting anything into an AI tool, remove or replace details that identify you — your name, student ID, university email, or login credentials. Swap them for placeholders like “[Name]” or “[Student ID].” You can also opt out of data training in the settings of ChatGPT, Claude, or Gemini so your conversations aren't used to train future models. Finally, avoid uploading entire essays or thesis drafts. If your text is stored in an AI tool's dataset and later surfaces in similarity-checking databases, your own work could get flagged as unoriginal when you submit it.

Learn to recognize phishing

Phishing is a form of cyberattack where scammers disguise themselves as trustworthy entities or individuals to get you to click suspicious links or reveal sensitive information. 

Recent phishing statistics are important to pay attention to. Email phishing is by far the most common type of attack, but other types of phishing include:

Spear phishing: A targeted attack where cybercriminals research you or your organization/university to craft highly personalized, convincing messages that often use your real name or student credentials.

Smishing: SMS phishing, or phishing conducted via text messages. These are often unexpected messages containing urgent alerts like fake package deliveries or tax refunds to reel you in. Usually, they contain malicious links or ask for personal information. 

Vishing: Voice phishing, where attackers impersonate bank representatives or government officials over the phone, using social engineering to ask for your passwords, PINs, or private information.

Signs of phishing attempts include an unusual sense of urgency, mismatched sender display names and addresses, suspicious links or URLs, and generic or unusual greetings (for example, “Dear Student” rather than your actual name).

To protect yourself from phishing, use a security tool like a next-gen antivirus from NordVPN. This tool inspects links after you click on them and checks the destination website in real time to make sure it’s legitimate. If it detects a phishing attempt, it blocks the site immediately. 

A next-gen antivirus also integrates with most email clients and browser extensions to analyze files and attachments and block fileless attacks and unauthorized code executions. 

What to do if you are hacked?

Getting hacked can happen in different ways, and even the smartest people may fall victim eventually. Here’s what to do if the worst happens. 

What to do if your device is hacked:

1. 1.Immediately disconnect from the internet or switch to airplane mode to cut off the hacker’s remote connection.
2. 2.Remove the malicious software by running a deep scan with a trusted antivirus scanner, while offline.
3. 3.Revoke hardware permissions to your camera, microphone, and location services in your privacy and security settings.
4. 4.Cover your webcam and turn off the device completely if it shows signs of unauthorized remote control.
5. 5.Check your downloads and applications folders for unfamiliar programs or extensions installed at the time of the breach, and delete them.
6. 6.Unplug and check any external hard drives or USB sticks.

What to do if your account is hacked:

1. 1.If you think one of your accounts has been hacked, immediately log out of all sessions and devices to terminate the hacker’s access.
2. 2.Change your login details immediately, using a new complex password. Remember to save these credentials in a password manager.
3. 3.Update your recovery information, and confirm it’s your email and phone number and not the attacker’s.
4. 4.Reset your multi-factor authentication and relink any authenticator apps.
5. 5.If you think your email account has been hacked, check your settings to verify the hacker hasn’t set up hidden rules to forward your incoming email or verification codes to themselves.
6. 6.Let your classmates, professors, and family members know that your account may have been hacked and advise them not to click on any suspicious links sent in your name.
