Email is by far the most common mode of business communication. However, it is frequently overlooked in terms of cybersecurity. Basic spam filters are no longer adequate. As many as 90% of cyber attacks begin with phishing, and it only takes one mistake for a catastrophic attack to occur.
Something has to change in this situation. As part of our series on best practises for security, we're taking a closer look at email security and some of the steps you can take in your business.
Phishing attacks have become more sophisticated in recent years, resulting in hundreds of thousands of breaches each year. However, there are some warning signs that your team can use to stop hackers in their tracks.
"Google will never send an unsolicited message asking you to provide your password or other sensitive information by email or through a link. If you're asked to share sensitive information, it's probably an attempt to steal your information."
Most corporations, including banks, will have a similar policy.
Accessing Wi-Fi that isn't password-protected poses a slew of risks to work devices. Email is particularly vulnerable. If you use public Wi-Fi to access your email, any malicious users on that network can essentially act as a middleman, intercepting any emails sent. Even if you don't open your email app, inboxes update automatically when you connect to a new network, so we recommend not connecting at all.
If you don't have a signal, using mobile data or a colleague's mobile hotspot is the way to go. VPNs can also be used, but only to encrypt data sent rather than to prevent it entirely.
When it comes to email, multi-factor authentication (MFA) is something to think about. This service adds an extra layer of security and virtually guarantees your safety from brute-force hacking attempts. Microsoft claims that MFA can prevent 99.9% of account compromise attacks.
MFA does not require any external hardware or complicated processes to be implemented. It doesn't even have to be implemented immediately across your entire team. We recommend beginning with a role-based approach, in which employees who handle the most sensitive data are the first to receive the most up-to-date security measures.
Best practises must be supported by the best software. There are numerous options for businesses to consider when it comes to securing their company emails. Password managers, spam filters, threat protection, and phishing awareness training are just a few examples.
