How Does Cloud Computing Affect Your Attack Surface?


In the world of information security, no topic gains more attention than the constantly evolving landscape of cybersecurity threats. One area of focus that organizations cannot afford to overlook is how their attack surface changes as they leverage cloud computing. But how exactly does cloud computing affect your attack surface? This blog aims to explore this question and divulge key insights concerning this issue.

Key Concepts

Before diving in, there are two crucial concepts to appreciate fully – ‘cloud computing’ and ‘attack surface’.

Cloud computing refers to the delivery of on-demand computing services that often include databases, networking, software, analytics, and intelligence over the cloud. Modern companies increasingly turn to cloud computing for greater efficiency, innovation speed, and cost savings.

The ‘attack surface’ of a system or network refers to the sum of all points or areas where an unauthorized user can try to enter or extract data. The larger the attack surface, the more areas need defending, which presents a bigger challenge for cybersecurity teams.

Pros and Cons

Cloud computing boasts various benefits, including scalability, cost-efficiency, and access from any geographical location. However, it also expands the attack surface, posing significant risks. Loss or leakage of data, insecure APIs, account hijacking, and malicious insiders are just a few risks associated with cloud computing. While taking advantage of the cloud’s benefits, organizations must also plan for these associated security challenges.

Best Practices

To manage the inflated attack surface due to cloud computing, various best practices can help:

1. Cloud Security Assessment: Periodically assess your organization’s cloud security posture to unearth vulnerabilities.

2. Least Privilege Access Control: Grant minimum necessary permissions to each user to limit unauthorized access.

3. Employ Security Automation: Leverage automation tools for round-the-clock monitoring and instantaneous threat alerting.

4. Regular Patching and Updates: Stay current with all required patches and updates to the cloud services you use.

Challenges or Considerations

While best practices can help, understanding the challenges is also crucial. The convoluted nature of cloud environments can make visibility and control challenging. Besides, the shared responsibility model of cloud security means that both the service provider and the user play roles in maintaining security. Also, the scaling of the cloud can lead to the rapid expansion of the attack surface, often beyond an organization’s control or even awareness.

Future Trends

Looking ahead, the complexity and scale of cyber threats are likely to increase, particularly as cloud environments become the norm. Companies will increasingly need to combine artificial intelligence (AI) and machine learning with human expertise to anticipate and mitigate threats effectively.


While cloud computing offers a wide array of benefits, it’s essential to recognize how it affects your attack surface and implement strategies to manage this extended range. Acknowledging the challenges, embracing best practices, and realizing future trends are the key to robust cybersecurity in this age of cloud computing.
