Artificial intelligence (AI) is creating new opportunities in the world of technology, automating and improving the efficiency of processes. When it comes to cloud security, AI has the potential to transform this field by providing much faster response times, improving threat detection and supporting proactive risk management. In this article we will explore the use and benefits of artificial intelligence in cloud security.
First, let’s explain what cloud security is. This term means all practices, technologies and policies implemented on cloud with the aim of protecting the infrastructure, data and applications from cyber attacks. Cloud security includes several areas as data encryption, network security, access and identity management or compliance.
¿Which are the principal challenges we faced when speaking of Cloud Security?
In recent years, the adoption of cloud computing has increased exponentially, which means that new challenges arise, including:
1.- Multi-tenant environments: It is common for multiple users to share the same resources. This environment paradigm increases the risk of data breaches through which a malicious user could gain access to other people’s data.
2.- Complex network architectures: when we talk about network architectures in the cloud, we are talking about complex designs that can therefore be difficult to secure if you do not have the necessary tools and knowledge.
3.- Dynamic infrastructure: Cloud infrastructure is dynamic by nature, which means it is constantly changing, adding complexity to threat detection and security controls management.
4.- Internal threats: in the cloud, many users (employees, partners, suppliers) access simultaneously, which increases the risk of data breaches such as theft or unauthorized access to stored information.
Benefits of AI in cloud security
Cloud security can benefit from artificial intelligence in a number of ways. Some examples:
1.- Proactive threat detection: Artificial intelligence can improve proactive risk management by analyzing threats in real time as the algorithms used by AI can analyze large amounts of data and identify anomalies and/or patterns that may represent a threat.
2.- Faster response times: Algorithms can reduce threat response times by automatically executing alerts and security checks.
3.- Predictive analytics: Artificial intelligence can detect threats even before they occur, using predictive analytics. This analysis is performed based on historical data to identify patterns and thus predict future events.
4.- Personalized security: AI algorithms can learn from user behavior to identify anomalies and generate alerts. In this way, controls can be customized based on users’ activity in the platform.
5.- Automation: AI can automate many security processes, reducing the workload of security teams, while also minimizing the risk of human error.
Artificial intelligence techniques used in cloud security
1.- Machine Learning (ML): is a technique based on the training of algorithms that learn from data. These algorithms can identify a threat based on the patterns and anomalies they identify. They can even predict future events.
2.- Deep Learning (DL): is a subset of Machine Learning that involves training deep neural networks. DL algorithms can learn from unstructured data such as videos and images, in order to identify threats based on certain patterns.
3.- Natural Language Processing (NLP): this technique is used to teach computers to understand human language. In this way, NLP algorithms can analyze data such as chats, emails, logs, etc. to identify possible threats.
4.- Computer Vision (CV): CV algorithms can analyze visual data like videos or images to teach computers to interpret this data, making it possible to detect possible threats.
AI in public cloud providers
The three major cloud providers, such as AWS, Azure and GCP, already use AI in some of the security services they offer. These are a few examples:
AWS GuardDuty: is a service that analyzes data from different sources such as VPC Flow Logs, CloudTrail, DNS logs to detect threats, based on AI and ML. Some use cases are the identification of compromised instances or port scanning.
Azure Sentinel: is a cloud-native SIEM that uses AI and ML to detect and respond to threats, both in the cloud and OnPrem. Some of the data sources used by Sentinel are activity logs, Security Center alerts or Office 365 logs.
GCP Cloud Security Command Center: is a data security and risk management platform that uses AI and Machine Learning techniques to detect security threats in Google Cloud environments. The data sources analyzed by this platform include virtual machines, Kubernetes clusters or buckets.
AI applied to Identity and Access Management
IAM (Identity and Access Management) is responsible for managing identities and permissions, so it is a key and critical aspect within the field of cloud security. AI can help us within this area, in different ways:
1.- Risk-based authentication: artificial intelligence can analyze user behavior and learn from this activity to detect anomalies or potential threats.
2.- Adaptive access control: with the support of AI, algorithms can learn from user behavior and automatically adjust the permissions set for users.
Artificial intelligence is transforming the world as we know it. There are more and more threats in the field of cybersecurity and this is where the use of technologies like artificial intelligence or machine learning can help us face these problems, improving response times and even anticipating possible future events. The main cloud providers are relying their security services on this technology, which is undoubtedly here to stay and to completely change the way in which we manage the security of our environments.
