What are the security risks of C-Mail forwarding?
Data Leakage:
- Sensitive information can be inadvertently sent to unauthorized recipients if forwarding rules are misconfigured or compromised.
Phishing and Spoofing:
- Attackers can use forwarding to redirect emails to external addresses, making it easier to conduct phishing attacks or impersonate legitimate users.
Compliance Violations:
- Forwarding emails outside the organization can lead to breaches of data protection regulations, such as GDPR or HIPAA, especially if sensitive data is involved.
Loss of Control:
- Once emails are forwarded outside the organization, you lose control over how the information is used or shared, increasing the risk of data misuse.
Increased Attack Surface:
- Forwarding can create additional entry points for attackers, who may exploit forwarded P-Mail emails to gain access to internal systems or information.
Audit and Monitoring Challenges:
- Tracking and auditing forwarded emails can be difficult, making it harder to detect and respond to security incidents.
What are some best practices for email security?
Use Strong Passwords:
- Create complex passwords that include a mix of letters, numbers, and special characters.
- Avoid using easily guessable information like birthdays or common words.
Enable Two-Factor Authentication (2FA):
- Add an extra layer of security by requiring a second form of verification, such as a code sent to your phone.
Regularly Update Passwords:
- Change your passwords periodically and avoid reusing old passwords.
Be Cautious with Links and Attachments:
- Do not click on links or open attachments from unknown or suspicious sources.
- Verify the sender’s email address before interacting with any content.
Use Encryption:
- Encrypt sensitive emails to protect the content from being accessed by unauthorized parties.
Regularly Update Software:
- Keep your email client and security software up to date to protect against vulnerabilities and threats.
Monitor Account Activity:
- Regularly check your email account for any unusual activity or unauthorized access.
Educate Yourself and Others:
- Stay informed about the latest email security threats and educate others in your organization about best practices.
Implement Email Filtering:
- Use spam filters and antivirus software to detect and block malicious emails.
Limit Email Forwarding:
- Disable automatic forwarding to prevent sensitive information from being sent to unauthorized recipients.
