Cloud Computing SECURITY AND COMPLIANCE CONSIDERATIONS
There are little question on-premises deployments of mission-critical business applications that provide more control over data because it resides within the four walls of an organization’s network infrastructure. However, businesses can not ignore the advantages of moving these applications to the cloud, including cost savings, scalability, flexibility, and modernization.
Unlike other tools that companies use, mission-critical business applications, like ERP, CRM, PLM, HCM, SCM, and BI, perform incredibly complex and integrated functions that keep businesses running, making the business heavily hooked into these applications. because their teams move these essential functions and their associated sensitive data to the cloud, it’s understandable they begin to feel concerns about security and compliance.
Before an enterprise makes any decisions, it’s essential to think about the highest security and compliance measures which will keep applications protected and up to regulatory standards before, during, and after migration. These seven areas are great building blocks for conversations with both SaaS and IaaS cloud service providers (CSPs), mission-critical application vendors, and businesses providing security technologies.
1. Data Residency and Compliance
From customer and financial information to human resources and property data, mission-critical applications house vast amounts of sensitive information. Top-of-mind regulations, like GDPR and SOX, can dictate where the info is stored, how privacy must be guaranteed, and when reports and controls are due.
When choosing an application vendor or cloud service provider, compliance is paramount. But sometimes the burden of proof can fall on the business. If CSPs and application vendors can’t support the extent of your business needs, consider choosing an answer that helps automate audit tasks, and addresses potential red flags. This visibility and automation can help address issues faster and continuously adhere to key regulatory standards year-round.
2. User Provisioning, Authorization, and Single Sign-On
. Without this data, employees can inadvertently cause serious security and compliance issues by exposing or sharing sensitive information they shouldn’t have access to within the first place. They also open the potential for bad actors to spoof worker logins and tap into a huge amount of critical data.
This area encompasses the management of access and important authorizations, ensuring segregation of duties is correctly enforced and other controls around user authentication, access, and authorization. For business applications, this is often closer to the normal approach to security and equally important to make sure the system is reliable to the business.
3. User Activity and Access Monitoring
Does an entry-level employee usually generate customer reports? Can a contractor always share sales data? Without understanding what baseline activity seems like, within their mission-critical applications, organizations are going to be unable to acknowledge anomalous activity when it occurs.
User activity and access monitoring functionality provides visibility to assist detect abnormal and malicious behavior. If you’re working with an IaaS or SaaS model, you would possibly require customized solutions, but the necessity for greater visibility into your application remains an equivalent.
4. Vulnerability Management
With a SaaS model, organizations shift patch accountability to the SaaS provider. In an IaaS model, businesses can outsource some patching to the CSP, but that generally doesn’t include patching your mission-critical applications. When it comes right down to it, protection should be a priority for the business.
Additionally, regardless of the cloud service model (SaaS, PaaS, IaaS), organizations must also assess for security vulnerabilities within the customizations and extensions of their business applications, as those are developed by humans and should contain security vulnerabilities.
Organizations should also work collaboratively to make sure systems are up-to-date with security patches. But because security teams have trouble maintaining with patch management thanks to the sheer volume of updates, technology vendors can provide tools that aggregate and prioritize patches supported the vulnerability level and risk for the precise business.
5. Disaster Recovery Planning
One of the foremost significant benefits of moving to the cloud is that uptime responsibility is shifted to the CSP. As a business, it’s now their job to stay the mission-critical applications up and running.
However, it’s still important to know the CSP’s plan should something fail. It’s also important to know what the program is internally should there be unexpected downtime within a neighborhood of your business’s key functions.
Cloud deployments and hybrid deployments provide flexibility to include better disaster recovery strategies, but that ought to be accounted for at the answer design phase – understanding that business applications are critical for the fulfillment, and will operate with resiliency from the beginning.
6. Due Diligence and repair Level Agreement
Understanding and validating compliance are often difficult. Some mission-critical business application vendors and CSPs provide standards they adhere to, while others are often difficult to know.
Companies moving to the cloud got to ask fundamental questions on the service level agreement between all the parties involved within the migration to know potential risks. Once all the knowledge is obtained, a risk management approach should be taken to look at the advantages against the potential pitfalls.
Finally, the foremost important concept to include in due diligence is that the approach of “trust but verify.” Even within the cases that the CSP is liable for security controls and security-related operations, the customer is ultimately liable for the info itself. it’s key to validate that the safety controls are correctly implemented. this could be checked periodically.
7. Incident Response
Since business-critical applications not only hold the foremost sensitive information a business has but also are the key driver to keep the organization running, hackers are increasingly homing in on vulnerable modules for attacks.
With recent IDC data showing, 64% of ERP deployments are breached within the last 24 months, businesses got to be ready for an event. This readiness starts with a response plan in situ but should include the right tools to spot, secure, and remediate the vulnerability when a breach occurs.
These seven points should be considered when migrating mission-critical business applications,, to cloud computing. Discuss these with CSPs and application vendors and when gaps arise, look for purpose-built security tools that help deliver the increased level of protection that’s needed within the cloud.
Finally, reports, guidelines, and checklists from leading independent workgroups, just like the Cloud computing Security Alliance, can help businesses prepare as they start the complicated journey of cloud migrations. While the journey needs careful and thoughtful planning, cloud migrations open up vast cost savings, flexibility, and business continuity benefits.
