The last IDC study confirms that Cloud is one of the most preferred storage solutions for companies. In 2017, total spending for Cloud infrastructure deployment jumped from 20,9% to $46,5 billion. Likewise, hybrid Cloud infrastructures (use of private and public Cloud) are more and more abundant.
The future of hybrid Cloud security
In 2017, public Cloud deployment increased the fastest (+26%). If spending on traditional infrastructures still represented the majority, it was in free fall in 2016 (-62%).
For 2018, Cloud will remain important and will become a competitive advantage "thanks to the value creation capabilities allowing by APIs" according to Diego Segre, IBM Europe vice-president and business partner. IDC predicts the spending to increase by more than 23% in 2018. According to the same study, investments in Cloud and particularly in public Cloud will continue to grow until 2021 to reach more than $277 billion in the USA.
According to Gartner, in 2018, 60% of companies having implement visibility and control tools for it Cloud will experience one-third fewer security breaches. And until 2020, public Cloud workloads are expected to suffer 60% fewer security incidents than those hosted in the traditional datacenter.
If Cloud tends to be democratized, the security of it remains the main concern for companies. However, a few simple elements are to take into account. We show you below, seven tips to start well and secure your hybrid infrastructure:
Tip n°1: plan the deployment
Time is money. This is also the hybrid Cloud main problem for businesses. Indeed, it wishes to migrate to a new infrastructure as quickly as possible to be operational and take advantage of the Cloud power. But, setting up such an infrastructure take times, and wanting to go too fast put its security in danger.
To properly organize its hybrid infrastructure, the company must view it as a new project to allow the necessary resources and time. It is imperative to build on solid foundations to avoid a complete resumption of a strategy that will have a direct impact on the business activity. Without this, the company could suffer financially from subsequent cyberattacks. And, when you know that in 2017, cyberattacks have cost $7,9 million on average to French companies, it is better to make upstream arrangements.
Tip n°2: restrict accesses
Enterprises make the mistake of thinking that everything on its network or Cloud is protected. But, without security tools (such as Elastic Workload Protector for example), it is not the case.
All data could be exposed in the Internet. To avoid that, you have to apply a zero-trust policy. This approach must be implemented in every environments and applications of the company. This latter has to verify, first of all, communications between its networks, infrastructures and applications. An access separation is also necessary, by level of responsibility (give certain privilege access to administrators) for example. It is judicious to give administrators and users access to only environments they need (development and pre-development environments and limitate the production for developers). Cloud providers (like Azure or AWS) provide these access managements.
Tip n°3: protect what is the most valuable: data
Companies must focus on what is the most important for them, which is it main asset. And data are often this precious asset. According to McAfee, any companies are looking to secure their data by restricting the access. Unfortunately, it is not the best solution, especially in a hybrid cloud. To identify their cyber risk exposure, companies must perform continuous security testing in order to improve the hybrid infrastructure global security process. Keys management (encryption or secret ones) is also essential to protect data, as well as virtual disks encryption. Carry out IT inventories continuously to gain visibility and standardize the security policy are also means to implement to protect data.
Tip n°4: strengthen policies and access rights
Skyhigh' survey (2016) of Cloud using revealed that each company used more than 1 400 different Cloud services. Likewise, an employee used in average 36 distinct Cloud services at work (collaboration, email box, files or content sharing services...).
In order to better manage these different services using, regroup access to it is the best option. Whereas Cloud providers offer to join identities, Identity Management solutions offer unique connexion portals. The best practise to set up, in order to reduce security risks due to multiple connexions is to have a unique authentication for each user.
Tip n°5: gain visibility for a more efficient and safer Cloud
Besides data protection and identity and access management, it is necessary for a company to have visibility. Gain visibility on your Cloud infrastructure is improving the management and the security of this one. Knowing in real time which resources and data are used by which users allow to be proactive in the potential security breaches management.
Security solution with API allow to make an inventory of the entire infrastructure, detects bad configurations hackers can exploit and brings it to the attention of the technical teams so they can be corrected before the creation of a malware. In addition, you can launch vulnerability scans continuously if you choose Elastic Workload Protector to better understand your risk of cyber attacks.
Tip n°6: automate security policies
Once users individually connected and the visibility improved, a strict and unique security policy for the all IT needs to be elaborated. Rules can be different according to Cloud services but the global action policy has to be the same. In addition, the goal is to centralize this security strategy management.
Policies, as well as efforts to increase visibility, also give the company a better chance of spotting abnormal behaviour or a breach. By setting rules and looking for malicious behaviour, IT security teams can detect attackers before they have time to do any damage.
Security teams alone do not have the time to continuously check the IT, that is why automatic Cloud security analysis solutions exist.
Tip n°7: reduce complexity and improve management with indicators
It is difficult to imagine driving a car without knowing its speed or fuel level for instance, the same goes for the management of a company and its security. To improve every cloud project security, organizations need data about their performance. Measuring success is important, as well as knowing it weaknesses. Visibility and security are the most important as the company's cloud projects grow, because hybrid cloud complexity issues will also grow.
Multi-Cloud and Hybrid Cloud are just a click away. The security of its infrastructure should no longer be a barrier in 2018. Learn more about how Elastic Workload Protector works. Our innovative Cloud Analytics solution fit all types of environments and can adapt to your various infrastructures.
