Defense in Depth (DiD): Think Like a Hacker

The National Institute of Standards and Technology (NIST) definition of DiD: “The application of multiple countermeasures in a layered or stepwise manner to achieve security objectives. The methodology involves layering heterogeneous security technologies in the common attack vectors to ensure that attacks missed by one technology are caught by another.”

Cybercriminals are always on the hunt for new ways to bypass security defenses, so think like a hacker and adopt measures to stay ahead of them.

Common threats to your business

1. Ransomware

This type of malware threatens disclosure of sensitive data or blocks access to files/systems by encrypting them until you pay a ransom. Failure to pay leads to data leaks or permanent data loss.

2. Phishing/Business email compromise (BEC)

Phishing involves cybercriminals masquerading as genuine persons or organization primarily through emails or SMS. They deliver links or executable attachments that initiate actions such as extracting login credentials or installing malware.

Business email compromise (BEC) is when cybercriminals use compromised or impersonated email accounts to manipulate you into transferring money or sharing sensitive information.

3. Cloud jacking

Cloud jacking - or hijacking - exploits cloud vulnerabilities to steal an account holder’s information and gain server access. With more and more companies adopting cloud solutions, cloud jacking is a significant concern.

4. Insider threats

These threats originate from within a business and may or may not be premediated. They come from current or former employees, vendors or other business partners who have access to sensitive business data; the origin may be very difficult to trace.

5. Denial-of-Service/Distributed Denial-of-Service (DoS and DDoS)

Common and easily executed, hackers flood the targeted system with multiple data requests, causing it to slow down or crash.

6. Artificial intelligence (AI) and machine learning (ML) hacks

Just as AI and ML are utilized for convenience to make significant technological progress in many applications, cybercriminals use these tools to develop an understanding of how businesses attempt to guard against cyberattacks and to prevent cyber incidents.

7. Internet of Things (IoT) risks and targeted attacks

Cybercriminals love IoT devices due to the ease of data sharing without human intervention and current inadequate legislation.

8. Web application attacks

Vulnerabilities within web applications permit hackers to gain direct access to databases to manipulate sensitive data. Many business databases contain sensitive data, including Personally Identifiable Information (PII) and banking details.

9. Deepfakes

A deepfake is a cyberthreat that uses artificial intelligence to manipulate or generate audio/video content that can deceive end users into believing something untrue. What do you do when you cannot trust your own eyes and ears?


Holding sophisticated cyberthreats at bay demands a robust DiD strategy. Layer multiple defensive methods, like firewalls, intrusion prevention and detection systems, endpoint detection and response (EDR), and more to build a security fortress.

DiD requires time and effort. Sydow, Inc. can implement and maintain your DiD strategy while you focus on your business.
