Top Five Cloud Security Myths

Security isn't taken for granted in the cloud... and that's the way it should be.

While movement to the cloud keeps accelerating, fears about security hang on. Let’s take a look at the most common myths about cloud security that might be holding businesses back from taking advantage of the flexibility and scalability of the cloud model.

1. The cloud is inherently less secure than enterprise data centers.
This is the piece of “common sense” that hangs on, but the data just doesn’t bear it out. Alert Logic, a provider of cloud-enabled security solutions, does regular studies of its customers, looking at the actual threats they experienced. For the last few years, they’ve been finding that cloud hosting provider customer are less likely to experience most types of threats, and when they are impacted, it’s less frequent that what’s seen in enterprise data centers.

Security isn't taken for granted in the cloud... and that's the way it should be.

2. Cloud security is my cloud vendor’s job.
Security is never your vendor’s job, no matter where your infrastructure lives. Yes, your vendors play an important role – but ultimately it’s your job. First, as part of your discovery process in choosing a vendor, you should be asking them about security – from their own physical security and management processes to the types of solutions they can offer through their partners. Second, when you are working with any IaaS provider, you are paying them to manage the infrastructure portion of the IT stack – there’s still an application layer that you’re in control of, and web-facing applications are a prime vector for attacks. Your vendor is your partner in building a holistic security strategy for your infrastructure.


3. Customers will not be comfortable with data residing in the cloud.
True, some customers won’t, but that’s not a concern based on data (see item 1). You need to remind your customers that data on a well-managed and properly secured cloud instance is much safer than data in an enterprise data center without proper monitoring for intrusion, without a rock-solid process for collecting and analyzing logs, without 24×7 monitoring of security data, or without a proactive process of identifying and patching vulnerabilities. It’s the management, not the location. If you’re looking at cloud options, you understand that; being transparent with your customers about how you protect them can go a long way to easing these fears.

4. The cloud is home to hackers and criminals.
Yes, there are bad guys using the cloud as a base of operations. Before the cloud, when dedicated hosting was hot, there were bad guys setting up shop at hosting providers. A good service provider will have a solid fraud management program to root out and boot out the bad actors. Ask them about it. And remember – even though there will always be some criminals using the cloud (and traditional hosting and their own data centers), what you need to worry about is what their targets are – and if you’re a target, where they’ve set up shop will be less relevant that the strength of your defenses.

5. Securing the cloud is too complicated.
This one has a basis in truth – securing cloud infrastructure is not the same as securing a traditional data center, much to the chagrin of traditional security vendors who’ve tried to shoehorn traditional products into a new environment with less than stellar results. Cloud security solutions have to be designed to work in multitenant environments. They need to be able to autoscale with cloud instances and they can’t depend on a server having the same IP address all the time. When you’re looking at security solutions, ask questions. How did the vendor handle cloud challenges? Do they work with the leading cloud infastructure vendors who are developing the technology that drives the cloud? In other words – are they cloud aware? If so, they’ll have cut through that complexity for you.

The bottom line: in the cloud, like everywhere else, security is critical. Your cloud provider should be ready to have frank discussions with you about the right approach – and a robust set of tools to keep your infrastructure safe. Let those discussions guide your cloud strategy, and you’ll have an advantage over businesses that are driven by myths.

Microservices are a type of software architecture where large applications are made up of small, self-contained units working together through APIs that are not dependent on a specific language. Each service has a limited scope, concentrates on a specific task and is highly independent. This setup allows IT managers and developers to build systems in a modular way. In his book, “Building Microservices,” Sam Newman said microservices are small, focused components built to do a single thing very w...

In most cases, it is convenient to have some human interaction with a web (micro-)service, no matter how small it is. A traditional approach would be to create an HTTP interface, where user requests will be dispatched and HTML/CSS pages must be served. This approach is indeed very traditional for a web site, but not really convenient for a web service, which is not intended to be good looking, 24x7 up and running and UX-optimized. Instead, talking to a web service in a chat-bot mode would be muc...
More and more companies are looking to microservices as an architectural pattern for breaking apart applications into more manageable pieces so that agile teams can deliver new features quicker and more effectively. What this pattern has done more than anything to date is spark organizational transformations, setting the foundation for future application development.
