Open networks

Protect yourself on open networks

If you connect to an open hotspot such as those commonly provided by hotels, you need to take additional steps to be sure your traffic isn't visible to hackers. Make use of a strong VPN to encrypt all of your traffic over the wireless network. You should also check the hotspot is legitimate when providing credit card details or login information, as sometimes cybercriminals set up fake hotspots.

Practice defense-in-depth

Network security is only one layer of a good security strategy. You should follow best practices for endpoint protection, patching and web security. With the right security practices you can keep yourself secure even if your wireless network is compromised, reducing the odds of a hacker getting away with your data.

Manage visitors and restrict traffic

If you are a business that needs to provide guest or consultant access, consider offering a separate network with restrictions on what guests can access. A hotspot registration portal can be an easy way to restrict access without a lot of administrative effort. Wireless solutions should enable you to easily deploy such networks, allowing visitors only access to the Internet and keeping them away from corporate services.

Manage your wireless access points

Make sure that your wireless access points (particularly those of branch offices and other locations) use the correct security configuration. Many enterprises may have secure wireless at headquarters, but then have weak access point configuration at branch offices. These can act as a back door to the enterprise, undermining your security efforts. Policy management and remote logging are therefore a priority to make sure security is consistent across your environment.
