Zero Trust: The Ultimate Business Power Move

Oct 16, 2024 | Cyber Security

Brief: As cyber threats evolve and proliferate, businesses need more than just traditional firewalls and VPNs. Enter Zero Trust—a game-changing security framework that demands a rethink of who and what to trust. This guide walks through how to build and implement Zero Trust, giving your business the proactive edge against insider threats and external breaches.

“The enemy is already inside. Assume breach. Protect accordingly.” — Unknown

Why Trust is No Longer Enough

For years, organisations relied on perimeter security—trusting anyone inside their network and blocking outsiders. But as remote work, cloud computing, and increasingly sophisticated threats blur these perimeters, businesses can no longer trust implicitly.

This shift requires a bold move—Zero Trust, where no user, device, or network can be trusted without verification.

What is Zero Trust?

At its core, Zero Trust assumes that no one—not even those inside the network—are to be trusted without verification. It enforces strict access control policies, granting only the minimal privileges necessary and monitoring every user, device, and transaction.

Three Core Pillars of Zero Trust:

  • Verify Every Access Attempt: Never assume a user or device is safe just because they’re inside the network.
  • Least Privilege Access: Users should only be granted the access they need, nothing more.
  • Assume Breach: Continually monitor, analyse, and log activity. If something looks off, treat it as a breach until proven otherwise.

Real-World Example: The Value of Zero Trust in Modern Cyber Security

 

Google’s BeyondCorp: Setting the Standard for Zero Trust

Google’s BeyondCorp initiative revolutionised its approach to internal security after the 2010 Operation Aurora attack, in which hackers infiltrated Google’s corporate network. In response, Google shifted to a Zero Trust model, ensuring every request for access, even from within the company, was thoroughly vetted and verified.

SolarWinds Attack: A Lesson for Everyone

In 2020, the SolarWinds attack exposed the weaknesses of relying on perimeter-based security. Attackers compromised software to gain access to the networks of multiple private-sector organisations and government bodies.

The Business Case for Zero Trust: Why Your Organisation Needs It

In today’s interconnected world, businesses face a higher threat level than ever before. From ransomware attacks to sophisticated phishing scams, cyber criminals are constantly evolving.

1. 85% of Security Breaches Involve Human Error

According to Verizon’s 2023 Data Breach Investigations Report, 85% of breaches are due to human error. Zero Trust minimises this by requiring continuous verification and Multi-Factor Authentication (MFA).

2. 70% of Companies Experience Insider Threats

A Ponemon Institute study found that insider threats account for nearly three-quarters of incidents. Zero Trust minimises these risks by enforcing granular access controls.

3. Fast Detection, Swift Response

According to IBM, the average time to detect and contain a breach is 280 days. Zero Trust can reduce this by detecting anomalies in real-time.

How to Implement Zero Trust in Your Organisation

Step 1: Enforce Multi-Factor Authentication

MFA adds an additional layer of security by requiring users to verify their identity with multiple forms of authentication.

Step 2: Segment Your Network

Network segmentation limits an attacker’s ability to move laterally. It proved effective for organisations during the SolarWinds breach.

Step 3: Enable Real-Time Monitoring and Alerts

Leverage AI-powered security tools to monitor networks in real-time and flag suspicious activities instantly.

Step 4: Continually Educate and Train Employees

Regular training helps staff recognise phishing attempts, deepfakes, and other social engineering attacks.

Zero Trust as a Power Move for 2024 and Beyond

Zero Trust isn’t just a security framework—it’s a business imperative. Are you ready to make the shift? Book a discovery session with F12 to create a Zero Trust roadmap tailored to your organisation.
