Cloud Security Threats Ranked Top 7 and Their Defensive Measures
Modern businesses can't escape the cloud - it's a crucial part of everyday operations. But, as more businesses interact with the cloud, the attack surface widens, making cloud-based attacks one of the top threats. In 2023, a staggering 80% of companies saw an increase in these attacks on their cloud environments. To keep your company afloat, protecting your cloud resources is a must. Here's a breakdown of the top cloud security risks, along with some real-world examples of breaches and strategies to fend them off.
1. Supply chain attacks
With the growing popularity of SaaS applications, supply chain attacks are on the rise. By compromise a single SaaS app, hackers can impact hundreds of companies and thousands – even millions – of customers. High-profile supply chain attacks in the last five years include both the SolarWinds and Colonial Pipeline hacks. In 2023, Okta, a leading identity and authentication management service provider for nearly 20,000 customers, disclosed a significant breach in which hackers were able to access the private data of Okta's customers and their customers. The breach went undetected for weeks, giving hackers ample time to wreak havoc.
2. Database attacks
Companies with extensive software development functions that are relying on vast cloud environments need to prioritize database security. Hackers can target unprotected databases using various tactics, including installing malware and SQL injections. The State of Software Supply Chain Security 2024, reported a 28% year-over-year increase in the total number of malicious packages uploaded to open-source repositories.
3. Vulnerability exploits
The rapid development cycles of SaaS applications lead to software vulnerabilities. As more organizations adopt cloud-based software, exploiting known and zero-day vulnerabilities is becoming a popular tactic for ransomware groups. The MOVEit breach was caused by a zero-day vulnerability, as was the EstateRansomware attack on Veeam's backup software.
4. Account compromise and credential stuffing attacks
With the number of SaaS applications in use growing, credential stuffing and account compromises present a growing threat. With something as simple as a leaked or stolen password and email address combination, hackers can test those same combinations across multiple SaaS applications, increasing their odds of success.
5. Misconfigured or exposed databases
A vast amount of sensitive data is exposed due to databases that weren't properly secured. This can be due to poor implementation of encryption, insufficient access control, or misconfigurations. In 2019, hackers stole the data of 419 million Facebook users from an unsecured database.
6. Advanced persistent threats (APTs)
APTs involve a hacker gaining unauthorized access to a network and sitting undetected for prolonged periods, typically conducted by state-sponsored groups. Cloud environments are ideal for APTs because ownership for their security is split between the cloud provider and the customer. Without the appropriate visibility or detection tools, hackers can lurk in the cloud and exfiltrate data.
7. Risk of non-compliance
Non-compliance with regulations can lead to fines, investigations, and negative publicity in the event of a data breach. After violating the NYDFS's Cybersecurity Regulation in 2023, OneMain Financial Group was fined $4.25 million.
To secure your cloud environment, implement 24/7 detection and response, visibility and monitoring tools, enhanced data protection tools, and access management protocols. A managed security services provider can help identify specific security needs and create an effective cloud security program.
