Every time our technology advances, we have to adopt a new essential set of skills. For instance, a few centuries back, no one had to know how to change a tire or reboot their computer system, but today, they’re essential.
For a 21st-century digital citizen, knowing why it’s unwise to give a stranger your phone “Just to make a quick call” is arguably as important as knowing which mushrooms in the forest are safe to eat to a medieval peasant.
With that in mind, here’s how better device hygiene can benefit your cybersecurity.
1. Monitor your own devices
It might sound like common sense, but always keeping your phone on you is key. It only takes a moment of inattention for someone to tamper with it. Plus, carrying it everywhere means you don’t risk leaving it unattended in risky environments.
While it might seem extreme, having software that lets you track your device can be a lifesaver if it’s stolen or tampered with. Also, using another device to keep tabs on your phone’s activity adds an extra layer of control over your own security. Just go through some of the best spy apps and pick the one that suits you the best.
Unlike your phone, which tends to stay locked, computers are often left open and accessible. Taking the time to log out prevents anyone from easily accessing sensitive data or accounts. Moreover, it ensures that you’re the only one using the device each time.
It only takes a few seconds for someone to install malware or, worse, a keylogger. Whenever there are others nearby, be extra vigilant with your devices. Even quick actions, like locking your phone, can prevent unauthorized access and keep your data safe.
2. Understanding common vulnerabilities and exposures
A common vulnerability and exposure, or CVE, is a unique identifier for known security flaws. Think of it like a serial number for vulnerabilities. Each CVE entry provides a name and description for a specific issue, making it easier for developers and cybersecurity professionals to address. Also, it helps everyone speak a common language about these security risks.
When a vulnerability is assigned a CVE, it’s publicly recognized and documented. This transparency is crucial because it alerts organizations and individuals to specific weaknesses that might be exploited. Moreover, with CVEs cataloged and accessible, software vendors can work on fixes, and users can take immediate steps to protect their systems.
Every CVE is a potential doorway into your system. Hackers look for these weaknesses to exploit, whether they’re in your software, operating system, or even connected devices. You can patch or update software before threats escalate by staying updated on CVEs relevant to your systems. Also, awareness of CVEs makes it easier to assess where your security might be vulnerable.
Staying aware of CVEs can feel overwhelming, but there are many ways to make it easier. The National Vulnerability Database (NVD) and tools like CVE feeds or notifications help you track new vulnerabilities as they’re reported. Moreover, many cybersecurity software solutions are programmed to alert you to CVEs affecting your system, simplifying your response process.
3. Regularly update your software
Setting updates to automatic is like setting your cybersecurity on autopilot. You’ll get the latest patches and fixes without even thinking about it. Moreover, it eliminates the risk of forgetting, so you’re always ahead of known security threats.
Not all updates are created equal, and security patches are the ones that matter most. These are the updates specifically designed to combat vulnerabilities. Ensure you’re updating apps you use the most, as they’re prime attack targets.
Some updates sneak in extra permissions that you might not notice. After each update, go back and review the permissions your apps have. This way, you maintain control over what apps can access, ensuring that none have unexpected privileges.
Unused apps are just dormant vulnerabilities. Go through your apps periodically and remove the ones you don’t need. Also, for those you decide to keep, make sure they’re up to date. This reduces your dev ice’s exposure to potential security risks.
4. Use stronger passwords and change them frequently
It’s tempting to reuse passwords, but doing so puts all accounts at risk if just one is compromised. Also, unique passwords make it harder for hackers to gain widespread access, limiting their reach to only what they can initially access.
Password managers are like your personal security vaults. They store and organize complex passwords, so you don’t have to memorize them. Also, they make it easy to access your accounts securely without reusing simple or easily guessed passwords.
Adding two-factor authentication (2FA) gives you an extra layer of security. You’ll need your password and an additional verification, like a code on your phone. Even if someone guesses your password, 2FA will stop them from logging in.
Changing passwords might feel like a hassle, but it keeps your accounts safe by reducing the risk of long-term exposure. Also, updating passwords for sensitive accounts every few months ensures that even if a password is compromised, it won’t be usable for long.
5. Limit access to your devices
If you let someone else use your device, make sure it’s someone you trust. Also, remind them not to log into accounts or download anything unexpected. Shared access can bring unexpected security risks, so it’s best to limit it.
Creating a guest profile allows others to use your computer without having access to your files. Moreover, it restricts their ability to install software or change settings, so you don’t have to worry about compromised security.
Lock screens are simple but effective. Make sure your device is locked whenever you’re stepping away, even for a minute. This way, no one else can quickly access your accounts or sensitive information while you’re away.
Leaving Bluetooth or USB open when it’s not in use opens up unnecessary access points. Moreover, it prevents any unwanted connections, so only the devices you trust have a chance to connect. Remember, the fewer open channels, the better.
6. Be cautious with public Wi-Fi
Public Wi-Fi can be a hacker’s playground. A VPN encrypts your connection, so they won’t see your data even if someone’s snooping. It’s also a good habit to have on any unfamiliar network.
Public Wi-Fi lacks the security of YouTube’s home or office network. It is best to avoid accessing banking apps or other sensitive accounts on public connections. If you must, ensure you’re using a VPN to help secure your data.
Some devices will automatically connect to any available network. Disable this feature, so you’re only connecting to networks you trust. Also, it’s easy to prevent your device from latching onto risky connections without your knowledge.
Your phone’s mobile data is usually more secure than public Wi-Fi. If you need internet on the go, consider using your hotspot. This way, you control the connection and reduce the chances of someone intercepting your data.
Keeping your devices secure is an ongoing commitment
By following device hygiene practices (like updating regularly, monitoring permissions, and staying aware of vulnerabilities), you’re actively reducing the risks that come with a digital life. You don’t have to be a cybersecurity expert; just a few good habits can make a difference. Ultimately, being proactive about device security keeps you one step ahead of potential threats, making your online experience safer, smoother, and more secure.
