Being out in public with your device often poses more threats (both physical and digital) to your information compared to being in your home or office environment. It is also worth considering who has access to that environment, an example being young family members that wouldn't consider the value of the device and it's data that they have access to.
Rogue Wi-Fi hotspot
A rogue Wi-Fi hotspot is an access point set up by an malicious user. It’s meant to mimic a legitimate access point provided by a business, such as a coffee shop that provides free Wi-Fi to its patrons. Most people don’t think twice before connecting to a free public Wi-Fi service.
Once connected to a rogue access point, the malicious user is able to eavesdrop on network traffic and potentially steal sensitive information such as account credentials and personal information. It also has the potential to provide access to your device for malicious software to be installed and run without your knowledge.
If you are unsure about a certain Wi-Fi access point, for example the wireless network requires no password or has a suspicious name; it is safer to either use your mobile data allowance, or just not connect. This will protect your device, as well as your personal data.
If you are on public transport or in a public location, refrain from accessing sensitive information such as corporate, personal and other confidential information as the possibility of ‘shoulder surfing’ (someone reading your screen behind you), or being overheard could occur.
Never leave your device unattended; whether it be in the library, unsecured office and especially out in public.
