    Most mid-sized to large enterprises have already moved some of their infrastructure,  data, and workloads into the cloud for better agility, efficiency, and cost savings. Nearly  three-quarters of businesses are running a hybrid and/or multi-cloud strategy today,  according to Forrester Research

    Cloud migrations are often part of larger corporate digital transformations that include  the adoption of DevOps strategies, microservices, APIs, containers, and more. Security  is never the driver — though it may be the most important passenger. Numerous surveys  of IT professionals show that security remains their biggest concern, and often an  outright obstacle to their cloud adoption. Companies want to know: 

    How can they ensure security and compliance controls are in place as they transition  to the cloud, and are not a barrier to transformation? 

    How can they ensure that security and compliance are consistent across cloud asset  deployments as well as the assets that remain on-premises? 

    How can they actually buy down the risk around their data with the right security  investments as they move to the cloud? 

    To make cloud transformations as efficient and successful as possible, companies must  remain secure and compliant throughout. And there are three keys to ensure secure and  compliant cloud migrations, which every enterprise IT and security leader should know.  They are: 

    Standardize security practices across your cloud, hybrid, and Multi-Cloud assets 

    Use modern security platforms built for the cloud automation era 

    Use Defense-in-Depth to protect APIs, applications and data, wherever they reside

 Standardize security practices 

across your entire hybrid/multi-cloud infrastructure 

Every company’s business transformation is different, and performed at a different pace.  Some companies jump in head-first, quickly moving all of their data and workloads off  premises onto Infrastructure as a Service (IaaS) public cloud offerings. Others move  more cautiously, keeping legacy applications and data on-premises, and surgically  creating a limited number of new workloads and processes in private clouds. Most  companies are somewhere in the middle, moving some data and workloads to a hybrid  set of public and private clouds from a variety of providers, but keeping other data in  place for unique strategic reasons.

Many companies choose a multi-cloud strategy in order to avoid overdependence  on any one vendor. Statistics back that up, showing that companies on average are  using almost 5 different public and private clouds today. With so many different cloud  deployment and service models available today,  the number of different clouds used by companies is set  to grow, not shrink. Flexibility, as you can see, is key. 

However, this cloud diversity creates additional governance and security challenges.  You still need to ensure that consistent compliance and security practices are followed.  Without strong controls and best practices everywhere, your business is neither secure  nor compliant. You don’t want to protect against a threat in your legacy on-prem systems  while leaving it undefended in the cloud.  

The environment sometimes dictates your security tools. But when you have a choice,  it can be quicker to achieve standardized controls through a comprehensive solution, as  long as the footprint is broad enough. This way, you can achieve a single pane of glass  that enables complete visibility across your enterprise.

 Modern security platform for the cloud  automation era 

Today’s cloud-enabled enterprises strive to be agile, collaborative, highly-automated,  and efficient. Manually moving workloads and technologies to the cloud is a step  backwards, being slow, labor-intensive, and error-prone. And that can ultimately lead to  more security vulnerabilities, as well as wasted time and money. 

That’s why modern enterprises are rebuilding or refactoring business applications on  microservices and cloud technology. They’re investing heavily in cloud orchestration and  automation to smooth and simplify every facet of their business IT infrastructure and  lifecycle processes. 

Take the modern agile development practice of Continuous Integration/Continuous  Delivery, aka CI/CD. Here, developers strive to deliver features and application changes  more quickly. Ensuring the code doesn’t inadvertently create security vulnerabilities is  key. However, manually combing through code to find potential vulnerabilities can slow  down the CI/CD process to a crawl. What’s needed is a solution that automatically spots  vulnerabilities, or prevents exploits by default. 

Organizations should adopt the same mindset where ever it must deliver security. Your  security solution shouldn’t just support the cloud, but actively enable and support  efficient cloud workloads and workload migrations with rich automation, DevOps, and  DevSecOps capabilities.

Modern enterprises also rely heavily on open APIs. On a technical level, APIs connect  public and private clouds, and help orchestrate the management of the data and  resources on them. On a business level, open APIs are key to building partner  ecosystems and accelerating innovation.  

To protect your cloud infrastructure, your security solutions must protect your critical  APIs and manage access to them by applications and users, including privileged insiders.  

Finally, your ability to rapidly deploy the protection your data needs at cloud speed can  hinge as much on your security vendor’s contract, as its technology itself. A software  license that provides flexibility and agility is key to success, too.

Defense-in-depth for applications, APIs  and data, wherever they reside 

One of the benefits of an on-premises-only infrastructure is the ability for security  teams to lock it down and minimize the attack surface. There is a massive cost to your  business, though, as you greatly hamper your employees’ productivity, and their ability to  innovate, partner, and quickly grab business opportunities.  

If not executed securely, migrating to the cloud can cause your organizations’ threat  surface to balloon, exposing you to a potential explosion of attacks and leading to  breaches whose financial damage outweighs all of your cloud-earned gains. To stay  ahead of threats while protecting cloud migration, you need a multi-layered security  architecture that provides autonomic defense-in-depth.  

Start with application security. Web application and API firewalls can be your first line of  defense, creating a hard-to-penetrate barrier against malware and hackers. Complement  that with DDoS protection to ensure your websites and applications remain up, even  when facing the most ferocious packet firehoses. Bot management can also quickly  identify and automatically prevent automated attacks, while Account takeover protection  leverages AI to block botnet traffic as well as attackers using stolen user logins.  

Moreover, security shouldn’t just guard the walls and perimeters of their clouds. For best  protection, it should reside adjacent or within the cloud applications and data. This will  protect your business’s crown jewels against insider threats such as careless handling,  compromised accounts, or privileged users that are malicious.  

Such data security should also include protection and oversight for data that is  increasingly stored in born-in-the-cloud databases, aka Databases-as-a-Service  (DBaaS), such as Amazon RDS, Azure SQL, Google Cloud SQL and others. 

Buying your risk down 

And remember: when implementing a defense-in-depth strategy, businesses are best  guided by a thorough threat assessment that takes a risk buydown approach. Creating  a comprehensive inventory of threats is a great first step. However, technology should  always serve business risk and outcomes. So the next step is even more key: calculating the potential financial losses if each of those vulnerabilities is exploited. Financial  damage can result from lost sales, regulatory penalties, brand reputation damage, and more.  

Using such an outcome-led methodology enables security teams to weight risk properly,  and invest rationally. Rather than buying impressive-sounding technologies simply for  their own sake, IT and security leaders can now put their dollars into security layers that  offer the greatest ROI in terms of reducing financial risk. In this way, a risk buydown  mindset works perfectly with a defense-in-depth approach.
