Survey: Security Lags as Cloud Use Rapidly Grows More Complex
BY SHAWNA McALEARNEY
Offering flexibility, convenience and speed to drive business initiatives, the cloud continues to present unrivaled opportunities for innovation—if it can be properly secured. Unfortunately, security efforts are still coming up short in many environments.
“Between the use of multiple cloud platforms and heterogeneous security solutions, to the lack of qualified personnel needed to implement and manage them, enterprises find themselves compromising security to achieve their business objectives,” according to FireMon’s The 2020 State of Hybrid Cloud Security survey of 522 IT and security professionals.

Building a Hardened Container Infrastructure—In and Outside of the Cloud
By MATT GILLESPIE
Bank vaults, mainframes and mountain fortresses are desirable for their lack of subtlety. Protection of their contents is ensured by sheer heft, so proprietors can focus elsewhere.
That calculus changes when low overhead is paramount. For instance, Linux containers epitomize lightweight, ephemeral infrastructure. And workloads that by design exist with only fleeting ties to physical systems must rely elsewhere for protection. Read More

Bringing PKI to the Cloud May Be Easier than You Think—And Already Happening
Most cybersecurity professionals are familiar with public key infrastructure (PKI) as it relates to creating and managing digital identities for people, platforms and devices across an enterprise. That increasingly includes building or outsourcing PKI within the cloud.
“We have always consumed PKI in the cloud, we just haven’t called it that because we have gone out and bought SSL certs that are publicly-rooted from the vendors,” explained Chris Hickman, the chief security officer for PKI-as-a-service provider Keyfactor, during an (ISC)2 roundtable discussion. “If we look at the history of certificates and how they were used, one could easily argue that PKI was actually one of the first applications in the cloud, by virtue of needing a certificate to protect my e-commerce website or my website. In general, that was what I did: I went out and bought a cert. That cert was from somebody who was providing PKI in the cloud. It is actually not a new concept.” Read More

Turning to History to Build Trust in the Cloud Era
By PAUL SOUTH
Amin Vahdat, a Google Fellow and technical lead for the company, is a student of history. The internet’s history, to be more precise.
In the early days of distributed systems, trust was implicit, he recalled. Protocols for routing and the like were not built with an adversarial mindset. Malware, phishing scams and state-sponsored cyber threats were rarely considered (at least publicly). Read More

Again: Who’s Responsible for Vulnerability Management in the Cloud?
By Shawna McAlearney
The debate about who is responsible for security in the cloud, ongoing since the earliest days of cloud computing, has now been tested, thanks to Spectre and Meltdown. Users may not like the answers they are getting from their cloud providers.
The new year ushered in not just one but two incredibly serious hardware vulnerabilities that posed both an immediate threat and long-term implications to cloud computing. These vulnerabilities, resident in many different vendors’ processors and operating systems, could be used to compromise most computer chips to read sensitive information stored in a computer’s memory, including account numbers and passwords.

Customers Have a Role in Reducing the Deluge of Cloud Breaches
By Teri Radichel
As the number of companies moving to the cloud increases, so do cloud breaches. In 2017, a variety of attacks on cloud systems occurred at major corporations and government agencies around the world. One of the most prevalent forms of cloud data leaks stemmed from improperly configured Amazon Web Services (AWS) S3 buckets. Organizations such as Verizon and Booz Allen Hamilton exposed credentials and sensitive data that existed in AWS storage buckets lacking proper configuration. These customers also failed to correctly encrypt the data. Read More

Using the Cloud for Disaster Recovery Requires Different Skills
By Crystal Bedell
It wasn't long ago that business continuity/disaster recovery (BC/DR) was reserved for the privileged few. Only the largest enterprises had the resources to build and maintain a secondary site, so only the largest enterprises had the peace of mind that comes with BC/DR capability. Today, however, that has changed. Cloud computing has democratized BC/DR, making it available to virtually any organization. The concern now is how to use cloud-based BC/DR securely.
According to analyst firm Enterprise Strategy Group (ESG), the number one planned use case for cloud computing is improving data backup and archive. BC/DR comes in second, and has for two years in a row, says Jason Buffington, a senior analyst for ESG. Read More
