Organizations are migrating to the cloud environment to gain agility, flexibility, and scalability in their business operations. Gartner predicts that by 2028, over 50% of companies will leverage cloud platforms to accelerate their business initiatives.
The increased dependence and popularity of the cloud environment expands the attack surface. These are the potential entry points, including network devices, applications, and services that attackers can exploit to infiltrate the cloud and access systems and sensitive data. All this ultimately intensifies the risk of data breaches and regulatory compliance issues. Statistics have found that up to 45% of data breaches occur in the cloud, and the average cost is $4.59 million.
As the possibility for hackers to access sensitive cloud data grows, it’s becoming crucial to address this address. By implementing the best security practices for reducing cloud attack surface, you can protect your digital assets and strengthen the overall security posture.
Understanding the Increased Cloud Attack Surface
The increased dependence on cloud services expands the attack surface. Several factors lead to the expansion of cloud attack surface, including:
Cloud Sprawl:
The adoption of hybrid and multi-cloud environments brings maximum benefits but, at the same time, poses significant security threats. Each cloud environment has its own set of security configurations, controls, and policies, which makes it challenging for the security teams to ensure consistent security across multiple providers.
Insecure APIs:
Cloud services rely upon APIs for seamless integration with third-party applications or services. As the number of APIs increases, they expand the attack surface for attackers to exploit. Hackers can easily target insecure or poorly designed APIs that lack encryption or robust authentication mechanisms and access data resources, leading to data leaks and account takeover.
Shadow IT:
The device or application not approved or supported by the IT team is called shadow IT. Since many of these devices and apps do not undergo the same security controls as the corporate ones, they become more vulnerable to hacking, putting the data stored within them at risk of manipulation.
Security Misconfiguration:
Unaddressed security gaps or errors threaten the cloud assets and data. Attackers can exploit misconfiguration and vulnerabilities in the cloud-hosted services, resulting in data breaches and other cyber attacks.
SaaS Apps Integration:
Cloud environments frequently rely on SaaS applications, which, besides providing operational advantages, introduce SaaS security threats. Vulnerabilities within these apps make them attractive targets for cyber adversaries. They can exploit the security flaws resulting in unauthorized access to sensitive data.
Malware Threats:
As the cloud environment has become more interconnected and accessible, the risk of cloud-native malware also arises. An analysis of the Dagon Locker Ransomware by the DFIR Report has shown how attackers use AWS knowledge to transfer and exfiltrate data.
Considering all these risks, organizations should adopt a strategic and proactive approach to safeguard their cloud networks.
Advanced Cloud Security Solutions to Add to Your Security Stack
Cloud attack surface reduction is a crucial element of any organization’s cybersecurity strategy. Security leaders must invest in various cloud-based services and solutions to fill the security gaps. Below is an insight into some of the best cloud solutions that improve security posture.
Cloud Security Posture Management
Businesses have started using Cloud Security Posture Management (CSPM) solutions that continuously assess and manage the security posture of the cloud infrastructure, applications, and services. Gartner predicts that businesses adopting CSPM solutions can cut down the cloud-based security incidents resulting from misconfigurations by an impressive 80%.
One advantage of using this cloud-native solution is its ability to enforce security policies across the cloud platforms. It applies various security controls like encryption which protects the data from being intercepted and reduces the risk of data breaches. Besides this, the CSPM solution also implements the policies of least privilege, ensuring users get limited access to resources necessary to perform their tasks.
Another benefit of using the CSPM tool is that it plays a vital role in ensuring compliance with industry-standard regulations like SOC2 and GDPR. By evaluating the cloud services against various compliance policies, CSPM identifies non-compliance violation risks and offers recommendations to address them.
Cloud Workload Protection Platform
The cloud workload protection platform (CWPP) is a great solution to secure cloud-based workloads such as containers, serverless functions, and virtual machines (VMs). By continuously monitoring the cloud network, CWPP recognizes vulnerabilities, detects malware, and implements data protection measures.
These solutions consistently enforce security policies and controls across public, private, and on-premises cloud infrastructure. This reduces complexity in managing security and strengthens the overall cloud security posture. It also employs advanced threat detection techniques, including behavioral analysis and machine learning to detect malware and other security threats. Apart from this, CWPP’s microsegmentation abilities enable developers and security teams to isolate workloads and limit lateral movement of threats within a cloud environment.
Cloud Access Security Broker
Cloud Access Security Broker (CASB) is a software tool that acts as an intermediary gatekeeper between cloud providers and cloud consumers to enforce security policies for secure cloud application access and usage. Using CASB gives organizations more visibility across the cloud applications usage, such as device information, and helps safeguard sensitive business data. It employs a Data Loss Prevention (DLP) tool that offers comprehensive visibility into the data moving across the on-premises and cloud environment. This enables security teams to ensure data security by monitoring user access to sensitive data. Also, it uses a combination of other security features, such as shadow IT discovery, encryption and tokenization, to protect cloud data and prevent data loss.
CASB solutions use advanced machine learning techniques and anti-malware and sandboxing technology to detect and mitigate potential threats in the cloud. Another benefit of this security solution is it offers compliance capabilities, which include automated remediation, reporting, and policy enforcement that help companies achieve their compliance objectives.
Best Practices and Recommendation to Enhance Cloud Security
As organizations migrate to the cloud platforms at an unprecedented pace, ensuring their security has become more critical than ever. Here are some of the best practices for minimizing cloud attack surface and boost security:
- Establish regular data backup schedules and use cloud backup solutions to store data in secure and off-site remote servers.
- Perform regular vulnerability assessment and penetration testing to discover and address potential weaknesses and vulnerabilities in the cloud environment.
- Implement robust data governance policies and conduct regular compliance audits to ensure adherence to regulatory requirements and industry best practices.
- Employ API gateways and management platforms for effectively managing and monitoring API requests. They offer features like request validation, caching, and rate limiting that are vital for reducing risks with insecure APIs
- Encrypt the cloud data in transit and at rest and implement proper key management practices to secure encryption keys. This ensures data integrity even if a hacker intercepts the data.
- Develop a detailed incident response plan that includes all the procedures and actionable steps to respond and recover in the event of a security incident or data breach.
- Keeping your software and operating system updated boosts the security of the cloud infrastructure. Enforce a robust patch management process that recognizes, tests, and applies security updates and patches.
- Educate and train all employees about cloud security, potential threats, their roles in protecting cloud data, and best practices to mitigate them. This highlights the importance of security vigilance and strengthens the overall security posture.
Final Thoughts
Businesses increasingly rely on cloud platforms to store, process, and manage their data. But all this ultimately expands the cloud threat landscape. Under such circumstances, businesses must stay informed about the latest cloud security threats and challenges. Using the right tools like CSPM, CAASM, andCASB, along with practicing security measures, helps strengthen overall cloud security.
