Defence in Depth (DiD): Think like a hacker

July 21, 2022

The current threat landscape is rapidly advancing, with cyber criminals constantly upgrading their toolset to break through security defences. If you want to outsmart malicious hackers, it’s time to start thinking like them. Fend them off with various layered defence methods. This is what Defence in Depth (DiD) is all about.

In simple terms, DiD is a cyber security approach in which multiple defensive methods are layered to protect a business. Since no individual security measure can guarantee protection against every attack, combining several layers of security can be more effective.

If you want to protect your business against cyber criminal masterminds, you must stay up to date with the ever-changing threat landscape.

9 threats to protect your business against

While there are numerous threats that businesses like yours must be aware of, let’s take a look at some of the most common ones you need to be aware of:

  1. Ransomware

    Ransomware is a type of malware that threatens to disclose sensitive data or blocks access to files/systems, by encrypting it, until the victim pays a ransom. Failure to pay on time can lead to data leaks or permanent data loss.

  2. Phishing/Business Email Compromise (BEC) 

    Phishing is a cyber crime that involves a hacker pretending to be a genuine person and/or organisation primarily through emails or sometimes other channels like SMS. Known as malicious actors, they use phishing to deliver links or attachments that execute actions such as extraction of login credentials or installation of malware.

    Business email compromise (BEC) is a scam that involves cyber criminals using compromised or impersonated email accounts to manipulate victims into transferring money or sharing sensitive information.

  3. Cloud jacking 

    Cloud jacking, or cloud hijacking, is when hackers exploit cloud vulnerabilities to steal an account holder’s information and gain server access. With an increasing number of companies adopting cloud solutions since the pandemic hit, IT leaders are worried about cloud jacking becoming a significant concern for years to come.

  4. Insider threats 

    An insider threat originates from within a business. It may happen because of current or former employees, suppliers, or other business partners who have access to sensitive business data. Because it originates from inside and may or may not be premeditated, an insider threat is hard to detect.

  5. Denial-of-Service (DOS)/Distributed Denial-of-Service (DDOS) 

    These attacks are common and easy to carry out. When DoS or DDoS attacks happen, 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 

    Artificial intelligence (AI) and machine learning (ML) are two trending topics within the IT world for their path-breaking applications. However, the downside is that AI and ML help hackers be more efficient in developing an in-depth understanding of how businesses guard against cyber attacks.

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

    The adoption of IoT is skyrocketing, and experts estimate that the total number of installed IoT-connected devices worldwide will amount to 30.9 billion units by 2025. However, data sharing without human intervention and inadequate legislation has made IoT a favourite target of cyber criminals.

  8. Web application attacks 

    Vulnerabilities within web applications permit hackers to gain direct access to databases to manipulate sensitive data. Business databases are regular targets because they contain sensitive data, including Personally Identifiable Information (PII) and banking details.

  9. Deepfakes 

    A deepfake is a cyber threat that uses artificial intelligence to manipulate or generate audio/video content that can deceive end users into believing something untrue.

Layer up

To help keep sophisticated cyber threats at bay, you need a robust DiD strategy. Your strategy should involve layering multiple defensive methods such as firewalls, intrusion prevention and detection systems, and endpoint detection and response, to build a security fortress that’s hard to crack.

To do this effectively takes time and effort, so it’s best to collaborate with a partner like Quintech who can implement and maintain your DiD strategy while you focus on running your business.
