Why You Need to Watch Out When Using Public Wi-Fi

By: McAfee

If you’re like most people, you like to stay connected whether you are traveling or just on the go. That’s why it can be tempting to connect to free, public Wi-Fi networks, but you should know that these networks could open you up to some serious risks.

Public Wi-Fi networks often lack a security measure called encryption, which scrambles the information sent from your computer or device to the router so strangers cannot read it. Without this security measure in place, the information you send over these networks can potentially be intercepted by cybercrooks.

This information could include your banking and social media passwords, as well as your identity information. A nosy cybercriminal could also potentially snoop on you by watching which websites you visit, and what you type into web forms.

In fact, it is so easy to steal your information over unsecured networks cybercrooks sometimes set up malicious Wi-Fi hotspots in high-traffic areas, like airports, with the intention of grabbing users’ information.

That’s why if you have to connect when you’re away, you should only use secure and well-advertised Wi-Fi networks. You can usually tell if they use encryption because they require a password to join.

If you have to do something sensitive online, like check your bank account balance or make a purchase, try to stick to webpages that start with “HTTPS” rather than just “HTTP”. The “S” stands for secure and indicates that the site uses encryption to protect your data. You can also look for a green lock icon at the beginning of the browser address, which indicates that the website connection is secure.

If you are on your mobile phone, you can skip the Wi-Fi network altogether and connect using the cellular network. It is somewhat more secure since it’s harder for cybercrooks to sniff out your individual data from others on the network.

If you travel a lot, consider investing in a Virtual Private Network (VPN), which is a piece of software that allows you to create a secure connection to another network over the Internet. Anyone potentially trying to snoop on you will only see that you are connected to the VPN, and not what you are doing.

Of course, the most important thing is to remember that using public Wi-Fi is always risky, and requires some extra steps to protect your data.

Here are some more tips to help keep you safe:

  • Think twice before connecting to any public Wi-Fi network, especially if it does not require a password to join.
  • Avoid using free, public computers. Cybercriminals sometimes place compromised computers in legitimate Wi-Fi hotspots with the intention of spreading malware or stealing your data.
  • Try to save sensitive transactions, like banking and online shopping, for your secure home or work networks.
  • If you do use a public network, stick to sites that begin with “HTTPS” so you know they are secure. The HTTPS Everywhere browser extension can direct you to encrypted pages when available. Also, look for the green lock icon in the browser’s address bar.
  • When using your laptop, make sure to turn off “sharing” of your folders and devices so no one else on the network can access them. A quick web search can tell you how to do this on your operating system.
  • Use comprehensive security software and keep it up-to-date. If your software includes a firewall, make sure to enable it.

Smart and Frictionless Zero Trust Access for the Workforce

Providing secure access and a frictionless user experience are typically competing initiatives, but they don’t have to be! Read on to learn why.

In our world today, context changes quickly. We work from home, coffee shops and the office. We use multiple devices to do work. And on the flip side, attackers are becoming increasingly savvy, getting around security controls, such as multi-factor authentication (MFA), to gain unauthorized access.

To quote Wendy Nather, Cisco’s head of Advisory CISOs, “Trust is neither binary nor permanent.” Therefore, security controls must constantly evaluate for change in trust, but without adding unnecessary friction for end-users.

It’s no surprise that the recently published Cybersecurity Readiness Index, a survey of 6,700 cybersecurity leaders from across the globe, revealed that more progress is needed to protect identity, networks and applications.

To address these challenges and to make zero trust access for the workforce easy and frictionless, Cisco Duo announced the general availability of Risk-Based Authentication and enhancements to our enterprise ready Single Sign-On solution at Cisco Live EMEA 2023 earlier this week.

Risk-Based Authentication

Chart showing how Risk-Based Authentication starts by evaluating the risk signal analysis based off of device trust, location, wi-fi fingerprint, and known attack patterns. Based of off this, it decides what kind of authentication is required - including no authentication, Duo push 2FA, verified Duo push, FIDO2 authenticator - before allowing (or blocking) access to corporate resources.

Risk-Based Authentication fulfills the zero trust philosophy of continuous trust verification by assessing the risk level for each access attempt in a manner that is frictionless to users. A higher level of authentication is required only when there is an increase in assessed risk. Duo dynamically detects risk and automatically steps up authentication with two key policies:

1. Risk-Based Factor Selection

The Risk-Based Factor Selection policy detects and analyzes authentication requests and adaptively enforces the most secure factors. It highlights risk and adapts its understanding of normal user behavior. It does this by looking for known attack patterns and anomalies and then allowing only the more secure authentication methods to gain access.

For example, Duo can detect if an organization or employee is being targeted for a push bombing attack or if the authentication device and access device are in two different countries, and Duo responds by automatically elevating the authentication request to a more secure factor such as phishing resistant FIDO2 security keys or Verified Duo Push.

Chart showing how Risk-Based Authentication, when picking up on known attack patterns, will either request a Verified Duo Push or Block access.

2. Risk-Based Remembered Devices

The Risk-Based Remembered Devices policy establishes a trusted device session (like “remember this computer” check box), automatically without asking the user the check a box, during a successful authentication. Once the session is established, Duo looks for anomalous IP addresses or changes to a device throughout the lifetime of the trusted session and requires re-authentication only if it observes a change from historical baselines.

The policy also incorporates a Wi-Fi Fingerprint provided by Duo Device Health app to ensure that IP address changes reflect actual changes in location and not normal usage scenarios such as a user establishing an organizational VPN (Virtual Private Network) session.

Chart showing how Risk-Based Authentication, when using location and wi-fi fingerprint to determine that risk levels are low, won't require authentication.

Duo uses anonymized Wi-Fi Fingerprint to reliably detect whether the access device is in the same location as it was for previous authentications by comparing the Wi-Fi networks that are “visible” to the access device. Further, Duo preserves user privacy and does not track user location or collect any private information. Wi-Fi Fingerprint only lets Duo know if a user has changed location.

Single Sign-On

A typical organization uses over 250 applications. Single sign-on (SSO) solutions help employees access multiple applications with a single set of credentials and allow administrators to enforce granular policies for application access from a single console. Integrated with MFA or passwordless authentication, SSO serves as a critical access management tool for organizations that want to implement zero trust access to corporate applications.

Chart showing how Duo SSO integrates with SAML 2.0 and OIDC applications

Duo SSO is already popular among Duo’s customers. Now, we are adding two new capabilities that cater to modern enterprises:

1. Support for OpenID Connect (OIDC)

An increasing number of applications use OIDC for authentication. It is a modern authentication protocol that lets application and website developers authenticate users without storing and managing other people’s passwords, which is both difficult and risky. To date, Duo SSO has supported SAML web applications. Supporting OIDC allows us to protect more of the applications that our customers are adopting as we all move towards a mobile-first world and integrate stronger and modern authentication methods.

2. On-Demand Password Resets

Password resets are expensive for organizations. It is estimated that 20-50% of IT helpdesk tickets are for password resets. And according to a report by Ponemon Institute, large enterprises experience an average loss of $5.2 million a year in user productivity due to password resets.

When logging into browser-based applications, Duo SSO already allows users to reset passwords when they have expired in the same login workflow. And we heard from our customers that users want the option to proactively reset passwords. Now, Duo SSO offers the convenience to reset their Active Directly passwords before they expire. This capability further increases user productivity and reduces IT helpdesk tickets.

Risk-Based Authentication and enhancements to Duo SSO are available now to all paying customers based on their Duo Edition. If you are not yet a Duo customer, sign up for a free 30-day trial and try out these new capabilities today!
