Cloud Security!

Cloud security is a collection of procedures and technology designed to address external and internal threats to business security. Organizations need cloud security as they move toward their digital transformation strategy and incorporate cloud-based tools and services as part of their infrastructure.

Why is cloud security important?

In modern-day enterprises, there has been a growing transition to cloud-based environments and IaaS, Paas, or SaaS computing models. The dynamic nature of infrastructure management, especially in scaling applications and services, can bring a number of challenges to enterprises when adequately resourcing their departments. These as-a-service models give organizations the ability to offload many of the time-consuming, IT-related tasks.

As companies continue to migrate to the cloud, understanding the security requirements for keeping data safe has become critical. While third-party cloud computing providers may take on the management of this infrastructure, the responsibility of data asset security and accountability doesn't necessarily shift along with it.

By default, most cloud providers follow best security practices and take active steps to protect the integrity of their servers. However, organizations need to make their own considerations when protecting data, applications, and workloads running on the cloud.

Security threats have become more advanced as the digital landscape continues to evolve. These threats explicitly target cloud computing providers due to an organization's overall lack of visibility in data access and movement. Without taking active steps to improve their cloud security, organizations can face significant governance and compliance risks when managing client information, regardless of where it is stored.

Cloud security should be an important topic of discussion regardless of the size of your enterprise.  Cloud infrastructure supports nearly all aspects of modern computing in all industries and across multiple verticals.

However, successful cloud adoption is dependent on putting in place adequate countermeasures to defend against modern-day cyberattacks. Regardless of whether your organization operates in a public, private, or hybrid cloud environment, cloud security solutions and best practices are a necessity when ensuring business continuity.

What are some cloud security challenges?

• Lack of visibility

It's easy to lose track of how your data is being accessed and by whom, since many cloud services are accessed outside of corporate networks and through third parties.

• Multitenancy

Public cloud environments house multiple client infrastructures under the same umbrella, so it's possible your hosted services can get compromised by malicious attackers as collateral damage when targeting other businesses.

• Access management and shadow IT

While enterprises may be able to successfully manage and restrict access points across on-premises systems, administering these same levels of restrictions can be challenging in cloud environments. This can be dangerous for organizations that don't deploy bring-your-own device (BYOD) policies and allow unfiltered access to cloud services from any device or geolocation.

• Compliance

Regulatory compliance management is oftentimes a source of confusion for enterprises using public or hybrid cloud deployments. Overall accountability for data privacy and security still rests with the enterprise, and heavy reliance on third-party solutions to manage this component can lead to costly compliance issues.

• Misconfigurations

Misconfigured assets accounted for 86% of breached records in 2019, making the inadvertent insider a key issue for cloud computing environments. Misconfigurations can include leaving default administrative passwords in place, or not creating appropriate privacy settings.

What types of cloud security solutions are available?

• Identity and access management (IAM)

Identity and access management (IAM) tools and services allow enterprises to deploy policy-driven enforcement protocols for all users attempting to access both on-premises and cloud-based services. The core functionality of IAM is to create digital identities for all users so they can be actively monitored and restricted when necessary during all data interactions

• Data loss prevention (DLP)

Data loss prevention (DLP) services offer a set of tools and services designed to ensure the security of regulated cloud data. DLP solutions use a combination of remediation alerts, data encryption, and other preventative measures to protect all stored data, whether at rest or in motion.

• Security information and event management (SIEM)

Security information and event management (SIEM) provides a comprehensive security orchestration solution that automates threat monitoring, detection, and response in cloud-based environments. Using artificial intelligence (AI)-driven technologies to correlate log data across multiple platforms and digital assets, SIEM technology gives IT teams the ability to successfully apply their network security protocols while being able to quickly react to any potential threats.

• Business continuity and disaster recovery

Regardless of the preventative measures organizations have in place for their on-premise and cloud-based infrastructures, data breaches and disruptive outages can still occur. Enterprises must be able to quickly react to newly discovered vulnerabilities or significant system outages as soon as possible. Disaster recovery solutions are a staple in cloud security and provide organizations with the tools, services, and protocols necessary to expedite the recovery of lost data and resume normal business operations.

How should you approach cloud security?

The way to approach cloud security is different for every organization and can be dependent on several variables. However, the National Institute of Standards and Technology (NIST) has made a list of best practices that can be followed to establish a secure and sustainable cloud computing framework.

The NIST has created necessary steps for every organization to self-assess their security preparedness and apply adequate preventative and recovery security measures to their systems. These principles are built on the NIST's five pillars of a cybersecurity framework: Identify, Protect, Detect, Respond, and Recover.

Another emerging technology in cloud security that supports the execution of NIST's cybersecurity framework is cloud security posture management (CSPM). CSPM solutions are designed to address a common flaw in many cloud environments - misconfigurations.

Cloud infrastructures that remain misconfigured by enterprises or even cloud providers can lead to several vulnerabilities that significantly increase an organization's attack surface. CSPM addresses these issues by helping to organize and deploy the core components of cloud security. These include identity and access management (IAM), regulatory compliance management, traffic monitoring, threat response, risk mitigation, and digital asset management.
