Why it’s Important to Secure your Network Beyond Passwords When Travelling – Driftwood Journals
If you’re going to protect your network at home or work, then you’ll need to understand passwords, and how to devise the most secure ones. But passwords alone, while fundamental, are just one component of a secure modern network. Many of the threats posed by today’s internet, which range from phishing to malware, are best addressed through a layered approach which brings together many different techniques.
This becomes even more important when travelling, as you’re often accessing accounts, devices, and sensitive information from unfamiliar locations and networks. So, what are these techniques, and how might they be used to protect your home network and your data while you’re away from home?
Use Multi‑Factor Authentication (MFA)
A password is just one means of proving that a user is authorised to access a given system. But passwords can be leaked or guessed. In order to truly secure a network, you might use other factors, like biometric markers of external devices, like phones. If you’ve ever been texted a one-time password, then you’ve made use of multi-factor authentication.
For travellers, MFA is especially valuable because it helps protect your accounts even if login details are compromised while using public connection abroad. Whether your accessing travel bookings, banking apps, or cloud storage, a second layer of verification can prevent unauthorised access.
Strengthen Network Defences with Firewalls and Encryption
A firewall, properly configured, can be an essential means of preventing certain kinds of access to your system. The good news is that most modern operating systems come with a firewall, and that by understanding how they work, you’ll have a great new means of protecting yourself and your data.
The same applies to encryption, which is fundamental to how modern browsers work, and an essential means of restricting access to sensitive data, especially while it’s in transit. Before travelling, it’s worth checking that your devices have firewall protection enabled and that all software is up to date, helping to reduce your exposure to cyber threats while on the move.
Secure Remote Access and Public Wi‑Fi Usage
Among the most popular forms of encryption today are Virtual Private Networks, which are a fantastic means of keeping your communications private, and interacting with a remote server without the possibility of third parties snooping on your transmissions.
There are VPN services available for a variety of platforms, and you can make use of yours with little technical knowledge. A VPN Mac client might allow you to get started right from Mac OS.
VPNs are particularly useful for travellers who regularly connect to hotel, airport, train station, or cafe Wi-Fi networks. These public connections can be convenient, but they may not offer the same level of security as your home network. Using one helps keep your browsing, logins, and personal data protected while you’re exploring new destinations.
Implement Continuous Network Monitoring
If you aren’t able to monitor your network, then you won’t understand when it’s under threat. The more quickly you can detect anomalies and act to deal with them, the better positioned you’ll be to keep your data safe.
As well as keeping an eye on network traffic, you’ll also want a system in place for regularly backing up and safeguarding your data. Thankfully, this is something that many cloud storage platforms offer by default, and you don’t need to.
For frequent travellers, remote monitoring can also provide peace of mind. Security alerts, device notifications, and cloud-based backups make it easier to spot suspicious activity and recover important files, even when hundreds or thousands of miles from home.
