Cloud computing is on a rise but one thing that always haunts organisations is security. It has always been the number 1 concern when it comes to public cloud. The hesitation has its roots in the belief that cloud systems are less secure than traditional systems. Unlike this debate, security is the top most common priority for both traditional and cloud environment. And with cloud coming with benefits like scalability, storage, elasticity and costs, a secured environment make it a totally worth it bet. Here, we bring to you possible cloud security challenges and expert tips to overcome these.
Security and Compliance Certifications
There are various standard security and compliance certifications in cloud computing and it is important to pay some attention to the cloud provider’s kitty. Certification such as ISO 27017:2015, ISO 9001:2008 and the Multi-Tier Cloud Security Standard Level – 3 are few of the reputed certifications that can be considered while making a decision over cloud providers. The financial ability of the providers to invest on secure technologies should also be considered.
IAM to Combat Cloud Security Challenges
Identity Access Management (IAM) are tools that help enterprises to manage user identities and access in the cloud. The IAM technology includes various services for identity management and access management. Most of the enterprises institute these along with other governance and authentication services. Also, it is important to do some white hat security tests to check the vulnerability of the IAM.
Cloud Access Security Brokers
CASBs or Cloud Access Security Brokers are in high demand these days. This trend is owing to the growing popularity of hybrid and multicloud models. This protects the data that is transferred between the client systems and cloud providers. CASBs also perform various analysis to track any suspicious behaviour.
Multicloud Security Snags
Multicloud computing enables a mix and match approach through which enterprises can choose different services and cloud providers as per their need. In most of the multicloud models, data travels across public internet increasing the risk of security. Besides, due to multi providers, there is lack of standardisation. One of the ways around here is educating teams on all security policies and establishing a common method for managing automation and monitoring across clouds.
Network Security Groups
These are really helpful in overcoming public cloud security challenges. Network security groups protect public cloud from outside access. They also help teams to manage access controls for networks in a public cloud. For different cloud providers, the process might be different and therefore it is important to study the set up of network security groups for the respective provider. To avoid potential threats, one should avoid accessing databases directly over the internet and should create a three-tier cloud security mode to control communication between apps and services.
A Multi-layered Cloud Security Framework
This is to ensure additional security. Here, the first layer is a secure virtual machine layer, the second layer is cloud data layer, their one is cloud storage layer and fourth is is virtual network monitor layer. Access to each of these layers should be restricted to only authorised users.
These are few cloud security tips that will help IT pros to overcome security challenges in a cloud environment. If you have any more insight or tips, feel free to mention it in the comment section below.
Are you constantly worried about cloud security? Have you been getting emails from clients on securing cloud environment? Here are 5 simple steps towards securing your cloud environment.
1. Peripheral Security – Define your security policies and identify access management
2. Network Security – Define security policies for VPC, VPN & ACL
3. Host Threats – To ensure protection from virus infections
4. Host Access Control – To ensure tracking for all login related activities
5. Application Security – Deploy web application firewall to avoid any form of attacks against applications
Cloud is the new normal
Around 3 years ago, this was a slogan that AWS followed but today it is a reality. Cloud is no longer an option in today’s age but almost a standard requirement of enterprises. Be it banking, ecommerce, retail or pharmaceutical, cloud is being used as a solution across industries. While bigger companies have started migrating to cloud, the smaller and newbies are building on cloud. Enterprises are building and operating services in the cloud and this shift in the last five years is huge. While security remains one of the most common discussions around cloud, enterprises are not talking about those concerns. Instead they are talking about how to operate hybrid platforms with on-premise and public cloud infrastructure. Thus, the trend of cloud computing being normal is pretty evident.
Do we have enough skills is the question?
While cloud is at its peak, the gap in the industry is for cloud computing skills. Cloud is emerging right from year 2012 and the demand is increasing. However, companies are facing issues in finding the right competencies in cloud. Continuous training in cloud has become a major challenge and a big necessity for the enterprises as AWS keep creating new products and releases. Recent studies state that large enterprises are investing big on developing cloud skills and conducting training programs to skill educate their developers. With players like Microsoft Azure and Google Cloud platform, there are a lot of certifications that is being introduced along with AWS cloud certifications.
AWS no more lonely
While AWS is still the leader in the cloud space, there are other players who have emerged and competing in the same space. Microsoft Azure is grabbing decent share in the market after AWS and their customer base is also on the rising trend. Google cloud platform is also gaining grounds but as compared to AWS and Microsoft Azure, it is quite far in terms of adoption and customer base. However, with the growing demand we might see aggressive competitions between these cloud providers.
Migration continues to accelerate
The graph of companies migrating to cloud is growing since last couple of years. While the initial shift was seen among small and mid-size companies, recently it is observed that large companies are also following the same path. A recent report has stated that while 77% companies relied on traditional infrastructure back in 2015, by the next year, this number is assumed to reduce to almost 45%.
Cloud security remains the big threat
Security is still the biggest concern when it comes to cloud computing. There are more security measures that is being introduced and adopted by developers. In the coming years, it is expected that security will become the basic feature of cloud where safety can be assumed.
Artificial intelligence the next big thing
The biggest players in cloud including AWS have introduced artificial intelligence based cloud services and looks like, this will be next big thing in this sector. There will be more automated deployment of products and data using cloud. Machine learning and artificial intelligence will shape the cloud industry quite a bit in the next few years.
These are few things that are trending in the industry. It would be interesting to observe these progresses in the near future.

Cloud computing is gaining grounds across industries. Not just IT but cloud computing is being extensively used in banking, hospitality, retail, ecommerce, healthcare and more industries. According to Gartner’s research, industries are viewing cloud computing as an evolving medium to succeed in the market place.
As compared to retail and ecommerce, banking and insurance are more hesitant to welcome cloud computing due to security issues. For instance, private clouds are more preferred in the insurance industry as they are considered more secure when compared with public clouds. On the other hand, in the banking sector, cloud is used for administrative functions like email and file sharing as the cloud environment might not be secure enough for banking transactions. Though security has evolved hugely in recent years in cloud computing, few industries have not accepted it with open arms due to lack of knowledge around security and well-equipped resources to manage cloud security.
While insurance and banking are reluctant to use cloud computing extensively, other industries like retail, media, ecommerce and manufacturing is using cloud as never before. In the retail industry, cloud implementations are majorly Iaas or Paas. All aspects like security, vendor maturity functions are deployed in cloud in the retail industry. Media for the obvious reasons of providing accessibility to users is exploring a cloud-based deployment to enable multiscreen entertainment. Manufacturing is massively using cloud for logistics, sales support functions, HR, product development and other manufacturing operations.
Cloud Computing in the Manufacturing IndustryManufacturing is one industry apart from IT that is making the most use of cloud computing. Let’s have a look at how cloud is revolutionizing the manufacturing industry.
