How To Build a Defense in Depth Strategy

To help understand what a defense in depth strategy is, imagine a castle surrounded by a moat, high walls, and a drawbridge. These fortifications were designed to protect the castle and its inhabitants from potential attackers. Modern organizations must take a similar approach to protect their valuable assets from various cyber threats.

A defense in depth strategy is a security approach that uses multiple layers of defense to protect against different types of attacks. Just like a castle’s defenses, a defense in depth strategy is designed to make it difficult for attackers to penetrate the organization’s perimeter and gain access to sensitive information.

Elements of a Strong Defense in Depth Strategy

To protect your organization against various types of cyberattacks, you need multiple layers of cybersecurity in place. Read on to learn some of the essential elements of a strong defense in depth strategy:


Investing in a firewall is a crucial aspect of a defense in depth strategy. Firewalls act as a barrier between the outside world and your environment, much like a moat around a castle. Firewalls help prevent unauthorized access and stop cyberattacks at the perimeter. As a result, they are often considered the first line of defense.

Next-Generation Antivirus

Hackers have become more sophisticated, and traditional antivirus solutions may no longer be enough to protect your organization. A next-gen antivirus solution can help prevent cyberattacks by checking all HTTP, HTTPS, SMTP, and FTP traffic for malicious code embedded within the traffic and blocking access to infected sites. If a firewall is a moat, then a next-generation antivirus is like a solider standing guard at the drawbridge.

Endpoint Security

Endpoint security solutions act as your castle wall and can help protect businesses by identifying more threats, enforcing compliance and policy, and ultimately reducing the cost of potential attacks. By opting for an endpoint security solution that includes detection, alerting, and response, you can better protect your endpoints.

DNS Protection

Paired with endpoint security, DNS protection can help further protect your environment from malicious attacks by blocking and filtering traffic to and from malicious sites infected with malware or having questionable or dangerous content.

Email Security

While looking at your infrastructure security is crucial, a defense in depth strategy wouldn’t be complete without looking at your IT security through the lens of potential weaknesses due to human error. Email is a prime example of that because it is the most common entry point for cyberattacks, and organizations need to take steps to protect against email-based threats. TPx’s Managed Inbox Detection and Response (IDR) equips your staff with an intuitive tool that offers easy reporting, automated scanning, and professional human threat evaluation of suspicious emails.

Security Awareness Training

To reduce human error even further, you should treat your employees as a defense mechanism against cyber threats. By employees with effective security awareness training, they can better understand proper cyber hygiene, the security risks associated with their actions, and ways to identify cyberattacks they may encounter via email and the web.
