Email Authentication And Security: Protecting Your Business Communication
In today’s digital world, email security can’t be an afterthought. Organizations must implement a multi-layered approach to IT security, encompassing everything from infrastructure to network setup. Just like other cyber threats, email scams and attacks constantly evolve. To stay ahead of the curve, robust email authentication is essential. Protect your sensitive information and hard-earned company reputation.
Don’t wait until it’s too late! Proactive email authentication is crucial to stop attacks before they happen.

Domain Attack Surface Management And Monitoring
Our Approach:
Email, the lifeline of your business communication, faces growing cyber threats. At CTS, our cutting-edge email authentication and security methods verifies senders and protects information. Safeguarding your organization from data breaches and financial losses.
As cybercriminals continue to advance their tactics, your digital environment demands robust authentication. We help configure and monitor using three must-have authentication methods; SPF, DKIM, and DMARC. Protecting your email domain and preventing phishers from harming your customers and hard-earned brand reputation
Inbound & Outbound Spam And Phishing
This service is commonly known as a Spam Filter. It can be integrated into your email server or provided as a third-party service. The Spam Filter scans and monitors all incoming and outgoing emails through your email server, such as Office 365. Its primary function is to safeguard against various threats including spam, phishing attempts, viruses, and malicious emails.
Domain Authentication
This process involves three key components, each designed to fortify your domain against spoofing and impersonation attempts. This includes:
- SPF, which stands for Sender Policy Framework
- DKIM, or DomainKeys Identified Mail
- DMARC, which stands for Domain-based Message Authentication, Reporting, and Confirmation
DKIM and SPF work alone, while DMARC combines all three to protect your sending domain.
Domain Authentication
SPF - Sender Policy Framework
This protocol gives domain owners the capability to specify a list of authorized email servers permitted to send emails on their domain’s behalf.
- EX – v=spf1 ip4:x.x.x.x include:spf.protection.outlook.com -all
DKIM - DomainKeys Identified Mail
This email authentication method adds a digital signature to outgoing emails. Ensuring the authenticity and integrity of the message by allowing the recipient to verify that the email originates from a legitimate sender and has not been tampered with during transit.
- This is implemented via CNAME records generated by your email server (Office 365)
- Selector_1 & Selector_2 keys
DMARC - Domain-Based Message Authentication, Reporting & Confirmation
This protocol empowers domain owners to instruct email receivers on how to handle unauthenticated emails sent from their domain by integrating the capabilities of DKIM and SPF and provides a reporting mechanism.
A 3rd party service to manage and monitor DMARC to provide reports and forensic data. Implemented in phases:
• Phase 1 – p=none : Take no action
• Phase 2 – p=quarantine : Deliver to the spam folder
• Phase 3 – p=reject : Don’t send the message at all
The Domain Authentication Power Trio:
DMARC, SPF, And DKIM
Domain Owner Publishes DMARC Record:
The organization owning the sending domain publishes a DMARC record within their DNS (Domain Name System) records. This contains precise instructions on how recipient mail servers should handle emails claiming to originate from the domain.
Incoming Email Arrives At Recipient's Mail Server:
When an email is dispatched from a domain implementing DMARC, it makes its way to the recipient’s mail server.
Mail Server Checks For DMARC Record:
The recipient’s mail server then scans for the presence of a DMARC record within the sending domain’s DNS.
SPF And DKIM Authentication:
Then, the mail server conducts SPF and DKIM authentication checks on the incoming email. SPF verifies the email's legitimacy by confirming its origin from an authorized server, while DKIM validates the email's integrity & authenticity through digital signatures.
DMARC Policy Check:
In the event of DMARC failure, the recipient’s mail server assesses the policy outlined in the DMARC record.
Reporting & Feedback:
DMARC incorporates reporting mechanisms in which the recipient’s mail server sends feedback reports to the domain owner. This provides details regarding email authentication results, failed attempts, and other information that facilitates the monitoring and enhancement of email security.
Strengthening CMMC Compliance: Integrating SOC, SIEM, & Email Authentication and Security
For organizations striving for CMMC compliance, strong email authentication and security is crucial. CMMC emphasizes the importance of data protection and emails are a prime target for breaches. Therefore, domain authentication protocols like SPF, DKIM and DMARC verifies senders and prevents phishing attempts from stealing sensitive data. In addition, SOC & SIEM provides an additional layer of cyber protection by monitoring and analyzing email traffic with quick detection & response to potential threats. Together, these cutting-edge cyber services provide the solutions needed for organizations seeking CMMC compliance.

















Benefits of Email Authentication & Security:
Stronger Defense Against Spoofing:
At CTS, our email authentication and security protocols help verify the legitimacy of all incoming emails. Therefore, it is much hard for hackers to spoof your organization's email address or trick employees into divulging sensitive information & data through phishing scams.
Protection of Brand Reputation:
Phishing scams that spoof your company's email address can cause serious harm to your hard-earned brand image and reputation. Email authentication and security protects against this by ensuring the legitimacy of your emails.
Improved Email Deliverability:
Traditional spam filters can often flag legitimate business emails as spam, especially if email authentication protocols are not in place. Therefore, implementing email authentication and security solutions can improve your sender reputation and ensure your emails reach intended recipients.
Regulatory Compliance
Email authentication and security measures, including SPF, DKIM, and DMARC, play a crucial role in achieving CMMC compliance by verifying sender identities and preventing phishing attacks. Implementing these measures ensures the protection of controlled unclassified information (CUI) exchanged via email, aligning with CMMC requirements for safeguarding sensitive data.
