During a recent Google Cloud Weeklies session on AI and data, the conversation revolved around multimodal strategies—the integration of various data types, cloud platforms, and AI models to optimise performance and drive innovation. As I listened, I was struck by how closely this concept aligns with best practices in cybersecurity. Just as businesses leverage multimodal AI to optimise performance and innovate, they must also adopt a multilayered defence strategy to protect their data and IT systems.
Just as AI thrives by processing information from multiple sources—structured and unstructured data, text, audio, and images—a strong cybersecurity strategy must also leverage multiple layers of protection. Relying on a single security solution is no longer sufficient in today’s rapidly evolving cyber threat landscape. Instead, businesses must implement a multilayered approach that includes everything from application security testing to proactive monitoring and cloud security solutions.
The Essence of Multimodal Strategies
In the realm of AI and data, a multimodal approach integrates different data forms—such as text, images, and audio—across multiple cloud environments and AI models. By harnessing diverse data sources, including previously hard-to-access “dark data”, businesses can unlock deeper insights and develop more robust solutions. For example:
Self-driving cars process images (camera feeds), radar signals, and real-time GPS data to make decisions.
AI chatbots combine voice recognition, sentiment analysis, and text-based data to provide more human-like responses.
This multimodal framework ensures AI systems are resilient, efficient, and capable of adapting to complex environments.
Why Cybersecurity Needs a Multilayered Approach
Cybersecurity operates on a similar principle—no single security measure can fully protect a business from modern threats. Attackers constantly evolve their tactics, and defending against them requires a layered, multi-faceted strategy that secures everything from networks and endpoints to cloud applications and data storage.
Effective cybersecurity isn’t just about stopping attacks—it’s about proactively mitigating risks across multiple layers, ensuring resilience against evolving threats.
Key Layers of a Multilayered Cybersecurity Approach
1 - Application Security
Ensures that software applications are designed and maintained to resist attacks. Regular code reviews, penetration testing, and security frameworks help identify and mitigate application-level threats.
Why it matters: Vulnerabilities in software applications are prime targets for attackers. Even minor coding flaws can become an entry point for malware or data breaches.
Key defences:
Static & Dynamic Application Security Testing (SAST & DAST)
Web Application Firewalls (WAFs)
DevSecOps integrations
2 - Endpoint Security & Detection Response (EDR)
Protects individual devices like computers, smartphones, and tablets from malicious activities. Implementing antivirus software, regular patch updates, and user education are crucial components.
Why it matters: Laptops, smartphones, and IoT devices are common entry points for cyber threats. Endpoint protection is critical in preventing ransomware, phishing, and malware attacks.
Key defences:
Endpoint Detection & Response (EDR)
Mobile Device Management (MDM)
Application whitelisting & disk encryption tools
3 - Network Security Management
Safeguards the integrity of data as it travels across internal and external networks. Firewalls, intrusion detection systems, and secure VPNs are essential tools for monitoring and defending network traffic.
Why it matters: Cybercriminals exploit network vulnerabilities to launch DDoS attacks, intercept communications, or move laterally through a system.
Key defences:
Intrusion Detection & Prevention Systems (IDS/IPS)
Next-Generation Firewalls (NGFWs)
Zero Trust Network Access (ZTNA)
Network Access Control (NAC)
4 - Cloud Security Solutions
Ensures data stored and processed in the cloud remains protected against cyber threats and unauthorised access.
Why it matters: With businesses relying more on cloud services, securing cloud environments is more critical than ever.
Key defences:
Cloud Access Security Brokers (CASBs)
Data encryption & configuration management tools
Threat intelligence platforms
5 - Identity & Access Management (IAM)
Manages and controls who can access systems, data, and applications within a business.
Why it matters: Unauthorised access remains one of the biggest threats to data security. Weak passwords, poor access controls, and phishing scams all contribute to data breaches.
Key defences:
Multi-Factor Authentication (MFA) & Single Sign-On (SSO)
Privileged Access Management (PAM)
Behavioural analytics for anomaly detection
6 - Password Management
Ensures that users create, store, and manage secure passwords to protect accounts and prevent credential-based attacks.
Why it matters: Weak passwords remain one of the most common entry points for hackers. Credential stuffing attacks, phishing scams, and brute force attempts exploit poor password practices to breach sensitive accounts.
Key defences:
Use of password managers to generate and store strong passwords
Regular password updates and monitoring for leaked credentials
Enforcing Multi-Factor Authentication (MFA) for added security
7- Cyber Threat Intelligence & Dark Web Monitoring
Provides real-time insights into emerging cyber threats and stolen credentials being traded on the dark web.
Why it matters: Hackers are actively trading stolen credentials and sensitive data on the dark web. Monitoring for these leaks allows businesses to act before a breach leads to financial loss or reputational damage.
Key defences:
Dark web monitoring for exposed credentials
Threat intelligence feeds to anticipate attacks
Automated incident response tools
Threat hunting
8 - Data Loss Prevention (DLP) & Compliance
Protects sensitive data at rest, in transit, and in use from being accessed, shared, or stolen by unauthorised users.
Why it matters: Data breaches often lead to regulatory fines, loss of customer trust, and operational disruptions. Therefore, it is critical to ensure data security at all stages.
Key defences:
Endpoint & Network-based DLP solutions
Cloud-based DLP tools
Privacy impact assessment platforms
Backup & Recovery
9 - Email & Domain Security
Ensures malicious emails are filtered before they reach inboxes while also preventing domain spoofing, phishing, and business email compromise (BEC).
Why it matters: 90% of cyberattacks begin with phishing emails. Attackers disguise emails as legitimate, tricking users into clicking malicious links, downloading malware, or handing over sensitive credentials. Without proper domain security, attackers can spoof legitimate business emails, leading to financial fraud and data breaches.
Key defences:
Secure Email Gateway (SEG) – Filters phishing emails, malware, and spam before delivery
DMARC, SPF, and DKIM authentication – Prevents attackers from spoofing company email domains
AI-powered phishing detection – Identifies suspicious patterns in emails before users interact with them
URL & attachment scanning – Blocks malicious links before they are clicked
10 - Staff Awareness & Security Training
Empowers employees to recognise and respond to phishing, social engineering, and cybersecurity threats, turning them into the first line of defence.
Why it matters: Human error accounts for over 80% of data breaches. Even the best security systems won’t help if an employee clicks on a phishing link, reuses weak passwords, or falls for a social engineering scam. Regular security training is essential to ensure employees can identify threats and take the right action.
Key defences:
Phishing simulation tests – Train staff to recognise fraudulent emails and scams
Security awareness training – Covers password hygiene, phishing, and social engineering tactics
Role-based access control (RBAC) – Limits employee access to only what they need
Incident response drills – Prepare employees to react correctly in case of a breach
11 - Proactive Monitoring & Threat Detection
Utilises continuous monitoring, AI-driven analytics, and security automation to identify and mitigate threats before they escalate.
Why it matters: Cyber threats are constantly evolving, and real-time threat detection is crucial in preventing data breaches and system compromises. Traditional security tools often operate in isolation, leading to missed connections between different security events
Key defences:
Security Information & Event Management (SIEM) systems
Automated threat detection & response (XDR, MDR, SOC Monitoring)
Extended Detection & Response (XDR) – Unifies endpoint, network, cloud, and email security into a single system for faster and more accurate detection
Behavioural analytics to detect anomalies
Bridging AI and Cybersecurity: The Synergy of Multimodal and Multilayered Approaches
In both AI and cybersecurity, diversity and redundancy are key to success. Just as AI integrates multiple data types and models, cybersecurity must incorporate multiple layers of defence to protect an organisation’s most valuable assets.
AI relies on various data types (text, images, video, audio) → Cybersecurity relies on various security layers (network, endpoint, identity, application security).
AI benefits from multiple learning models for resilience → Cybersecurity benefits from multiple defence mechanisms to prevent breaches.
AI adapts in real-time to changing inputs → Cybersecurity must continuously evolve to address new threats.
