Machine learning focuses on a computer algorithm that accesses and analyzes an immense amount of data to make accurate predictions and decisions. The cause of malfunction in machine learning is due to adversarial attacks. The need for adversarial attacks is to help the hackers to misappropriate and gather the required information. The use of adversarial attacks is both ethical and unethical way. The notable use cases are hacking confidential information, unethical hacking, cybersecurity, and many more.
Adversarial machine learning is a specific technique used in machine learning to misguide a model with spiteful input and execute an adversarial attack. Adversarial examples are implied in machine learning models as input to produce the mistake in the model. An adversarial example is a fraudulent version of a valid input, where the corruption is done by adding a disturbance of a small magnitude to it. Adversarial machine learning can be considered either a white or black-box attack.
The most common strategies of adversarial machine learning are evasion attacks, poisoning attacks, model stealing, and inference. Some popular methods of adversarial attacks are Limited-memory Broyden-Fletcher-Goldfarb-Shanno (L-BFGS), Fast Gradient Sign method (FGSM), Jacobian-based Saliency Map Attack (JSMA), Deepfool attack, Carlini & Wagner attack (C&W), Generative adversarial networks (GAN) and Zeroth-order optimization attack (ZOO).
Several defense mechanisms were also developed for the machine learning models, such as threat modeling, attack simulation, information laundering etc. Some real-world applications of adversarial attacks are spam filtering, computer security, malware and computer virus analysis, cyber warfare, and more intelligent applications. Future scopes of adversarial attacks focus on building perturbation mounting methods and adversarial attack detection methods.
Improved Model Robustness: AML techniques can help enhance the robustness of machine learning models, making them more resilient to various attacks. This is particularly important in critical applications like cybersecurity, where adversarial attacks can have severe consequences.
Enhanced Security: By identifying and defending against adversarial attacks, AML contributes to the overall security of machine learning systems. It is crucial in applications involving data privacy, financial transactions, or sensitive information.

Increased Trust in AI: As AML techniques become more widely adopted, they can help build trust in AI systems among users and stakeholders. Knowing that models are designed to resist adversarial manipulation can instill confidence in their reliability.
Improved Generalization: Adversarial training, a common AML technique, often results in better generalized models. It means they perform well on a broader range of inputs, including those not specifically encountered during training.
Adversarial Attack Sophistication: Adversarial attackers continually develop more sophisticated and creative attack techniques. Keeping up with the evolving nature of adversarial attacks is a significant challenge, as defenses must adapt to new and unknown threats.
Lack of Theoretical Foundations: This lacks a comprehensive theoretical framework for understanding why adversarial examples work and how to prevent them. This makes it challenging to develop robust defenses based on well-established principles.
Scalability Issues: It can be computationally expensive, making scaling for large and complex machine learning models challenging. Training robust models often require significantly more resources than training non-robust models.
Data Limitations: Gathering and creating adversarial training data can be difficult and costly, especially for domains where labeled data is scarce or expensive. It limits the applicability of AML techniques in certain settings.
Evaluation Metrics: Determining the effectiveness of AML techniques and assessing model robustness requires the development of appropriate evaluation metrics, which can be challenging to define and implement.
Legal and Ethical Concerns: AML techniques can raise legal and ethical concerns, particularly when applied to sensitive domains such as healthcare or criminal justice. Ensuring that AML practices align with legal and ethical guidelines is crucial.
Computer Vision:
Image Classification: AML protects image classification models from adversarial attacks, ensuring they remain accurate and reliable even when faced with manipulated or perturbed images.
Object Detection: Adversarial examples can be crafted to confuse object detection systems. AML techniques help defend against such attacks, which are crucial in applications like autonomous vehicles.
Natural Language Processing (NLP):
Text Classification: Applied to protect text classification models such as sentiment analysis or spam detection from adversarial text inputs designed to mislead the model.
Language Generation: AML can be used to defend against adversarial inputs that aim to manipulate the output of language generation models, ensuring they produce appropriate and safe content.
Healthcare: Adversarial techniques safeguard medical image analysis models, ensuring accurate diagnoses even when medical images are tampered with. Also, protecting patient data in healthcare systems from adversarial attacks is another important application.
Cybersecurity: AML is applied in intrusion detection systems to detect malicious network traffic, malware, and cyberattacks that use adversarial techniques to evade detection. It also protects the critical infrastructure and systems from adversarial attacks is a significant application of AML in cybersecurity.
