The rise of cloud services has made it easier than ever for businesses to operate and collaborate remotely. This has also led to a surge in the use of business email services such as Gmail and Microsoft Exchange. However, this convenience comes with an increased number of different types of email attacks. If attackers are able to gain access to your business email account or other cloud services, they could potentially wreak havoc on your company’s operations and expose sensitive data - with consequences that can last long after the attack. In this blog post, we’ll take you through some of the ways you can secure your business email and protect your company from cyber threats.
Know Your Email Service Provider (ESP) Basics
Use Strong Passwords and MFA
Implement Email Encryption
Monitor your Network Activity
- Password brute force attacks: Attackers try to guess your password. They may also use a password harvesting tool to access your account.
- Social engineering: Attackers try to trick you or your employees into giving up your login credentials.
- Malware: Attackers install malicious software on computers and devices within your network. This malware can give attackers remote access to your systems.
- Phishing: Attackers send spoofed emails that try to trick you into clicking malicious links or downloading harmful attachments.
- DNS poisoning: Attackers redirect the DNS server to point to a server under their control. This can allow attackers to intercept traffic, such as emails, and redirect it to a server they control. You can use network monitoring software to track the activity and alerts on your network. This can help you detect malicious activity before it results in a breach.
Lock Down Privileged Account Use
- Require multifactor authentication to access sensitive accounts.
- Restrict the amount of time an individual has access to an account.
- Log account activity and terminate accounts if they’re no longer being used.
