Encryption in Public Clouds

Why Cloud Data Encryption Matters?

In recent years, you have likely heard the term data encryption come up in conversation more frequently. As an ever-growing amount of our data becomes digital, the need for proper encryption has become increasingly important.

The integration of digital technology into all areas of business has resulted in more of our data being stored on computers and websites targeted by hackers. This has significantly increased the number of data breaches occurring, put encryption into the public spotlight, and heightened organizations’ vulnerability to malware attacks. For numerous reasons, like misconfigured storage repositories and unpatched vulnerabilities, this trend is likely to continue. Data encryption interest, products, and research are all on the rise due to these aforementioned factors.

Encryption’s Role in Preventing Ransomware

As mentioned, data encryption has been big news as of late but not in a way IT professionals would have hoped. From stolen consumer information to sensitive data leaks, it seems that no one’s data has been safe as of late. Data encryption’s ascendancy to the public conscience emerged with the proliferation of a type of malware attack called ransomware.

The effects of these attacks have been far reaching—the Equifax breach impacted 145 MM consumers and the recent breach of a top hotel chain resulted in nearly 500 MM consumers’ data being hacked. In addition to these large-scale attacks, companies must also keep in mind that more employees working remotely on a wide range of devices expands the threat landscape.

The effectiveness of data encryption in ransomware also highlights why it should be a cornerstone of any company’s security posture. Given its capability to make data unreadable to those who do not have the key to unlock it, encryption can be a powerful tool for protecting data confidentiality. We are now moving to a world where every piece of data should be encrypted, whether in transit between devices or stored at rest in your servers.

Encryption and the Public Cloud

The meteoric rise of the public cloud has compounded the need for proper data encryption, as data security requires new knowledge and skill sets in short supply, often leading to misconfigured and insecure solutions. Companies need to adopt the approach that every piece of data in their possession, on-premises or in the cloud, must be encrypted to protect confidentiality in the event of a security breach.

Practices to Mitigate Leaks

In order to fully understand data encryption, you’ll first need to learn the basics of encryption, the prerequisites of data confidentiality, key management, and how data encryption works in each of the top tier public clouds. There are many practices to mitigate data leaks, and the guide below delves deeply into these respective practices. This includes a discussion of what the CIA triad means for data encryption, symmetric or secret key encryption, envelope encryption, and other unique encryption methods specific to AWS, Microsoft Azure, and Google Cloud.
