For complex cyber threats, AI security plays an important role in defending businesses. As businesses migrate to cloud and hybrid environments, they face challenges like data sprawl and expanded attack surfaces. Cybercriminals continuously develop new tactics to exploit these vulnerabilities, while the shortage of cybersecurity experts only adds to the pressure.

The number and severity of cyber-attacks are rising steadily. Recent data shows that the global average cost of a data breach reached $4.45 million in 2023, a 15% rise over three years. This surge underscores the growing need for AI security solutions to combat these threats.

AI security automates threat detection and response, catching cybercriminals in action and reducing potential damage. Advanced AI tools can identify malware, isolate harmful software, and block repeated login attempts to prevent brute-force attacks. This proactive defense enables businesses to stay ahead of attackers and protect sensitive data.

AI-powered systems continuously analyze data, adapting to new attack methods in real-time. By evolving with each threat, these systems enhance their ability to detect even the most sophisticated cyber risks. This adaptability is key in minimizing vulnerabilities and maintaining robust security.

Companies that neglect AI security face significant financial losses. Data breaches in organizations without AI security cost an average of USD 5.36 million, 18.6% higher than the global average. Even those with basic AI security reported a substantial reduction in breach costs, proving its value in reducing financial risks.

However, AI security is not without its challenges. Its effectiveness depends heavily on the quality of its training data. If this data is biased or tampered with, it can lead to incorrect threat detection and flawed decision-making. For instance, biased data could skew hiring processes, favoring certain demographics unfairly.

Cybercriminals also leverage AI to amplify their attacks, automating the search for vulnerabilities and launching more convincing phishing scams. Recent findings reveal that AI-driven cyberattacks are on the rise, with 75% of senior cybersecurity leaders noting an increase in such incidents.

Despite these risks, only 24% of current AI projects are sufficiently secured. Moving forward, organizations must prioritize secure AI development to harness its benefits while upholding ethical standards and safeguarding against misuse. Investing in AI security is essential to stay resilient in the face of evolving cyber threats.

3 Pillars of AI Security

AI Data Security
Machine learning and deep learning models require diverse, large, and reliable datasets for effective training, validation, and retraining. Ensuring that training datasets are well-represented is crucial to avoid biases in the AI model. Yet, to adhere to global privacy laws, these datasets must be pre-cleaned and anonymized, which is often overlooked by many organizations.

Neglecting structured AI data storage and failing to secure data in transit can expose systems to severe threats like data theft or data poisoning—two significant challenges in AI security.

Risk: Privacy and Copyright Breaches
Building a robust AI model generally demands ten times more data than the model’s parameters. Yet, global privacy regulations limit how AI developers can use customer data in model training. Despite this, some developers continue using personally identifiable information (PII) without proper legal consent.

Companies like Spotify and OpenAI have faced substantial legal issues due to non-compliance. Spotify was fined $5.4 million for not disclosing data usage in its AI model under GDPR regulations. OpenAI is also dealing with legal challenges for allegedly using copyrighted personal data without proper authorization. New regulations like the EU AI Act and the UK’s AI Regulation Bill are emerging to strengthen data confidentiality measures and control unauthorized data use in AI models.

Solution: Data Minimization and Anonymization

Without strong anonymization measures, sensitive data might leak into the AI model’s training dataset, creating two significant risks:

  • Legal Compliance Issues: Organizations might fail to meet required privacy protection standards.
  • Cybersecurity Threats: Hackers can manipulate AI models to reconstruct sensitive training data and commit data theft.
    To counter these risks, adopting privacy-preserving techniques is essential for robust AI security. Methods like homomorphic encryption (HE), differential privacy, secure multiparty computation (SMPC), and federated learning are valuable tools. For example, Sony’s privacy toolbox integrates several of these techniques, automatically cleansing datasets of sensitive information and using secure training algorithms. Their approach also evaluates the AI model’s resistance to known threats like model inversion and membership inference attacks (MIA).

Risk: Data Poisoning
Data poisoning attacks aim to manipulate the training data, introducing biases or errors that degrade model performance. Even minor data tampering can cause “concept drift,” where the AI model misclassified objects—like identifying Ford cars as Ferraris. More severe attacks can fully compromise AI security, leading to model dysfunction.

A recent breach demonstrated the scale of this risk when a cybersecurity firm accessed 723 accounts with exposed HuggingFace API tokens from major companies like Meta and Google. This access created a vulnerability, allowing attackers to alter the data directly, paving the way for large-scale data poisoning.

Solution: Data Validation and Ongoing Model Monitoring

The OWASP AI Security and Privacy Guide outlines essential practices to shield AI systems against data poisoning:

Data Quality Checks: Integrate automated checks into data pipelines to ensure incoming data accuracy.

Layered Data Protection: Use encryption, firewalls, and secure transfer protocols to protect training data.

Advanced Model Monitoring: Continuously track model performance for any anomalies or sudden changes in data patterns.

Leading AI teams also use a strategy of training multiple models on varied data subsets, then combining them into a single predictive ensemble. This approach boosts AI security by minimizing the risk of data poisoning, as attackers would need to compromise several models simultaneously to succeed

Robust Model Development

AI models and software systems are both vulnerable to threats, either through flaws in coding or dependencies. Insecure code or unmonitored dependencies can create gaps in your model’s AI security, inviting cyberattacks. Additionally, using open-source libraries or pre-trained models often introduces hidden vulnerabilities that compromise your company’s security.

Risk: Exposed Model Components
The rapid evolution of AI tools, libraries, and frameworks has accelerated model development. Open-source and commercial solutions have democratized access, speeding up AI innovation. Yet, depending on third-party tools significantly raises the risks to AI security.

Researchers have shown how manipulated machine learning models can distribute malware within organizations. Tests using PyTorch have proven this risk, and similar vulnerabilities exist in TensorFlow, scikit-learn, and Keras. When companies pull pre-trained models from public sources like HuggingFace, they may unknowingly expose themselves to AI threats.

Solution: Strengthen Your Development Toolchain
Secure all AI development components—hardware, software, libraries, APIs, and infrastructure—from trusted providers. This reduces the AI security risks from external dependencies. Follow NCSC’s guidelines for improving supply chain security in technology acquisition, especially for AI systems.

Always scan pre-trained models for tampering or misuse. Modern security tools can detect malicious code hidden within machine learning files, enhancing overall AI security. Apply robust software development practices using standards like ISO/IEC 27090 and OWASP ASVS to ensure all AI components are secure.

Risk: Underperforming AI Models
Building generative AI models is resource-intensive, yet over 80% of these models are abandoned before deployment. Even deployed models often fail to meet expectations due to AI security lapses or inadequate real-world adaptation.

Real-world data often deviates from training datasets, leading to reduced model efficiency. Studies by Sophos revealed that high-performing malware detection models quickly degrade when exposed to real-world conditions. Rushing a model’s release can create technical debt, compromising its security and driving up operating costs.

Solution: Address AI Technical Debt
Weak AI model performance is often due to hasty development decisions that favor immediate gains over long-term AI security. Google’s analysis highlighted several causes of technical debt in machine learning, which can undermine a model’s reliability:

  • Data Entanglements: Mixing data sources makes it challenging to optimize model components individually.
  • Hidden Feedback Loops: Misleading data correlations can lead to biased AI model outputs.
  • Undeclared Consumers: Models feeding untracked systems may generate unforeseen dependencies.
  • Data Dependency Issues: Unnecessary data packages increase complexity without adding model value.
    AI teams must focus on eliminating technical debt to enhance model performance and reduce costs. Establishing robust ModelOps practices—like continuous integration, model versioning, and automated retraining—can significantly strengthen AI security. This approach ensures quicker model releases without compromising on robustness or quality.

Enhanced Model Operations

Deploying AI in production environments presents significant challenges. Real-world usage exposes AI models to evolving threats, making AI security crucial. Attackers often target these models to manipulate outputs or access other systems. Research has even shown how GPT models can be exploited to deliver harmful code into developer environments.

Risk: Data Breach and Leakage
Securing AI models is essential to prevent unauthorized access to user inputs or outputs. Hackers can exploit vulnerabilities to extract sensitive data from model memory. Google Brain’s project revealed that even minor tweaking could expose confidential data, like fake social security numbers.

Data leaks also happen through technical errors. For instance, OpenAI experienced a data breach in March 2023, exposing users’ personal details. Such incidents underline the need for stringent AI security protocols to protect data integrity.

Solution: Implement Comprehensive Data Management
Implement strong data management practices to safeguard against data breaches. Identity and Access Management (IAM) controls are crucial for restricting data access to only authorized personnel. Model version control systems (VCS) help track changes and prevent unauthorized use of sensitive data.

Encrypt data in storage and during transmission to reduce breach risks. Generative AI models should include input validation to block malicious data entries. Companies like JPMorgan have embraced advanced techniques like fully homomorphic encryption (FHE) and privacy-preserving machine learning (PPML) to enhance AI security.

Risk: Adversarial Attacks on Models
Evasion attacks pose another threat to AI security. Hackers use prompt injections or exploit design flaws to manipulate AI behavior. For instance, researchers at Tencent altered Tesla’s autopilot performance with minor visual changes.

Such attacks may also involve phishing attempts targeting Machine Learning-as-a-Service (MLaaS) users to steal AI models. These attacks not only degrade performance but also risk data and intellectual property theft.

Solution: Reinforce AI Security Policies
Effective asset management is key to robust AI security. Maintain an accurate inventory of AI assets and track their usage. Apply strict data management policies, enforcing minimal access principles for sensitive data interactions.

Adopt cryptographic model signing techniques to certify AI models’ integrity for downstream users. This approach strengthens AI security by preventing unauthorized modifications and ensures greater trustworthiness.

Risk: Model Drift
Model drift undermines the predictive accuracy of AI systems over time. Changes in data patterns or evolving tasks can lead to this degradation. For instance, Zillow’s property valuation model significantly miscalculated house values, costing millions in losses.

Model drift can manifest as data drift or concept drift. Data drift occurs when input data distributions change. Concept drift arises when the core task the model addresses shifts. Both scenarios pose severe risks to AI security and decision accuracy.

Solution: Continuous Model Monitoring and Retraining
Deploy automatic drift detection systems to identify early signs of model degradation. Algorithms like the Population Stability Index (PSI) and Kolmogorov-Smirnov (K-S) tests are effective for data drift detection.

Monitor key performance metrics like recall, precision, and F1-score to track concept drift. Continuous oversight helps distinguish natural drift from malicious interference. Automated retraining can enhance model reliability, driving better operational insights and reducing downtime.
