Cloud computing is the engine of modern business. During the pandemic, it's helped organizations to transition to and sustain mass remote working, optimize IT and enhance resilience. But with this digital transformation comes new cyber security threats.
Comprehensive cloud computing security is essential to mitigate the financial and reputational risks of cyber attacks. It should be multilayered and based on a strong and clear understanding of your responsibilities as a customer of a cloud services provider.
Cloud computing security basics
The most important first step to securing your cloud computing security environment is getting to grips with the shared responsibility model. Broadly speaking, doing so will enable you to understand which part of the environment the cloud provider will secure and which areas are your responsibility. No matter whether you're running on-demand software (SaaS), cloud platforms (PaaS) or cloud infrastructure (IaaS), your data is always yours to secure.
What do attacks look like?
Cloud computing security assets were involved in around a quarter (24%) of breaches last year, according to Verizon's most recent Data Breach Investigations Report. The main risks to your data and cloud systems are:
- Information theft, including customer data and highly sensitive intellectual property.
- Ransomware, which could hobble your organization by locking you out of your cloud accounts.
- Cryptocurrency mining, or malware that secretly mines for digital currency, running up large power bills and degrading equipment.
- Distributed denial-of-service (DDoS) attacks, which could take down your cloud-hosted applications and disrupt the customer experience.
