Electronic communications travel over large networks with many different parts. The scale and complexity of these networks, such as the Internet, mean there are potential security concerns when communicating electronically.
The primary concern with electronic communications is that it's possible for someone to intercept a message without the sender or recipient noticing. There are different ways this can be done, such as a “man-in-the-middle attack”, but this should not be a cause for alarm for Canadians provided due caution is observed.
In today's digital age, a large amount of personal information is shared electronically, by phone, email, text, and online. It is especially important to take steps against potential eavesdroppers. Using the following precautions can help:
- Be aware of what information is considered sensitive. This can range from banking details to dates of birth. Not everything you send or receive is sensitive, but be selective about when and who your share this information with.
- Use encryption to protect personal information. Doing business online depends on sending personal information. Encryption protects it. Many websites and browsers automatically encrypt traffic between each other.
- Exercise caution when using certain technologies. Some devices are less secure than others. Wireless technologies, such as Bluetooth, can be vulnerable to interception.
- Assess how trustworthy a network is. Some networks are more trustworthy than others. For example, a properly secured home or office Wi-Fi is generally safer than publicly available Wi-Fi. Do not trust or connect to unknown networks.
Secure communications are important to protecting your business' and customer's privacy and security.
