Fail-safe is not just a term that evokes the Cold War era — it is a basic principle of safety and security engineering. Things will inevitably go wrong, and when they do, these safeguards all the difference in how they go wrong and with what consequences. While passengers would be inconvenienced if a railroad signal system malfunctioned and trains came to a halt, there is no real, lasting harm done as long as there are no train wrecks.

This is a classic example of fail-safe behavior, but the principle applies just as strongly to cloud and third-party risks. Unfortunately, many organizations are failing to take protective measures to keep their data safe in the cloud and in the hands of third parties.

Minimizing Cloud and Third-Party Risks

According to Infosec Island, the need for fail-safe protective measures exists even in the absence of deliberate attacks. In one recent instance, a telecommunications company shared customer data with an analytics firm, and a cloud service “bucket configuration” error caused the unprotected customer data to go live on the open internet.

This was a case of innocent error, but that doesn’t change the potential damage done. In real life, organizations must contend not only with human mistakes, but also with malicious acts ranging from sophisticated malware attacks to phishing emails and other social engineering attacks targeting employees.

Preventing Data Security Train Wrecks With Encryption

The good news is that fail-safe protections are available to minimize cloud and third-party risks — they just need to be used. Broadly speaking, valuable or sensitive data can be either destroyed or stolen. The basic protection against data loss is secure off-site backup.

But the greater current threat seems to be data theft, for which the basic fail-safe protection is encryption. Encrypted data can still be stolen, but it is useless to the thieves. The theft is also harmless to the victim organization, since encrypted data cannot be exposed or compromised. Even the likelihood of theft is diminished, because once data thieves run into encryption, they lose interest and go looking for more vulnerable victims. As media headlines show, they don’t have to look very far.

A Fail-Safe Layer of Security

The bad news is that too many organizations fail to use encryption to protect their data. There are the usual excuses about complexity, overhead and the problems of key management. There is also a widespread perception that encryption is suitable only for data at rest, not for application data. But encryption technology has made great strides, allowing data to be protected at the application level with granularity extending to the columnar level.

The cloud and complex third-party relationships are here to stay, and organizations are still responsible for securing their data. Encryption can provide a powerful fail-safe layer of security to ensure that your data is protected even when it is out of your hands.

How Posture Management Prevents Catastrophic Cloud Breaches

We've all heard about catastrophic cloud breaches. But for every cyberattack reported in the news, many more may never reach the public eye. Perhaps worst of all, a large number of the offending vulnerabilities might have been avoided entirely through proper cloud configuration. Many big cloud security catastrophes often result from what appear to be tiny lapses. For example, the famous 2019 Capital One breach was traced to a misconfigured application firewall. Could a proper configuration have prevented that breach?…

How to Implement Cloud Identity and Access Governance

Creating identity and access governance across cloud environments is crucial for modern organizations. In our previous post, we discussed how important human and non-human identities are for these environments and why their management and the governance of their access can be difficult. In the face of these challenges, our cloud identity and access governance (CIAG) approach offers an orchestration layer between cloud identity and access management (IAM) and enterprise IAM, as the following graphic shows. As we continue our CIAG…

How Do You Plan to Celebrate National Computer Security Day?

In October 2022, the world marked the 19th Cybersecurity Awareness Month. October might be over, but employers can still talk about awareness of digital threats. We all have another chance before then: National Computer Security Day. The History of National Computer Security Day The origins of National Computer Security Day trace back to 1988 and the Washington, D.C. chapter of the Association for Computing Machinery’s Special Interest Group on Security, Audit and Control. As noted by National Today, those in…

Why Are Cloud Misconfigurations Still a Major Issue?

Cloud misconfigurations are by far the biggest threat to cloud security, according to the National Security Agency (NSA). The 2022 IBM Security X-Force Cloud Threat Landscape Report found that cloud vulnerabilities have grown a whopping 28% since last year, with a 200% increase in cloud accounts offered on the dark web in the same timeframe. With vulnerabilities on the rise, the catastrophic impact of cloud breaches has made it clear that proper cloud security is of the utmost importance. And…
