With the increase in businesses migrating to the cloud for vital strategy formulation, extension and competition, companies recognize the requirement for new security concerns. Surprisingly, as it would seem, among the respondents to the Ermetic-IDC survey, two-thirds of CISOs claim that their organizations have been victims of a cloud data breach during the last 18 months. Remember, 38% targeted them much more frequently, with 10 or even 100 breaches.
The benefits of cloud computing are evident, but its risks also have to be protected. Organizations must be cautious while treading this modern information technology landscape. They need to understand both what cyber security can offer them in terms of improvements and what it will take to protect the accountability of their business, staff, and clientele from cyber threats.
What is Cloud Security Architecture?
Cloud security architecture reveals the approach of both the provider and the user in their joint effort to ensure the security of the cloud. It divides the responsibility of those who are supposed to safeguard and the ways.
People involved in business, providers or customers, handle the specific technical features in their related sectors or departments. Secure cloud applications and the control of access to them also occur.
For securing apps, examples of measures include:
- Encoding data for transfer and keeping it as safe as possible while it is being stored
- Developing tools like website application firewalls or bot management to prevent system attacks and secure data extraction.
- Detecting and destroying malware. Preventing unauthorized access to critical data is significant.
- Monitoring the reports and log activities throughout the cloud environment.
For access to apps, security measures include:
- Regarding network security solutions, SASE (secure access service edge) is the most prospective as network protection must rely heavily on the cloud, combined with SD-WAN, secure web gateway, and cloud access security broker.
- Authentication techniques like multi-factor authentication (MFA) and single sign-on (SSO) are umbrellas to protect the organization and users from data breaches and fraud.
- Remote access mechanisms are designed through the recommended VPN-less proxy secure digital offices.
The security architectural design is significant because cloud security is complex. Risks such as uncontrollable device access, failure of MCNPs, and hazards like APTs require attention. The abbreviations as a service include models like infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS) and desktop as a service (DaaS), where both the provider and the customer manage their unique architectures.
When it comes to cloud security, who should take responsibility?
The answer to what security tasks in the cloud are shared by the cloud service provider and the user might ultimately depend on the type of service and how it will be used; however, cloud security duties are usually shared to some extent. Another example is when customers engage the services of an IaaS provider from a public cloud provider. The provider will take care of the physical interfaces, the hypervisors and the data storage layer. Meanwhile, customers will only handle the application level or the Operating System/Data layer.
This infrastructure is the cloud, where the provider takes care of the low-level details like the optimal software for computing, database, and other hardware usually maintained by the cloud center. Meanwhile, the client will instead concentrate on the aspects, such as permission to access and firewall configurations.
In Public Cloud services like Platforms as a Service (PaaS), Software as a Service (SaaS), and Desktop as a Service (DaaS), more security features are provided by the cloud provider, unlike in Infrastructure as a Service (IaaS), where the responsibility for security falls more on the cloud consumer. For instance, in a SaaS setting, consumers are not required to be in charge of server administration, database management, encryption encodings, and so on. However, this shouldn’t discourage businesses from recognizing that SaaS still carries risks; users must assess the provider and determine how to manage application access securely.
The ownership of the private and hybrid clouds is typically attributed to the companies that are solely meant for their use. This type of cloud shifts the responsibility of cybersecurity to the companies. On one hand, there is undoubtedly an increase in the level of security in private as well as hybrid cloud data, brought about by a reduced dependence on shared infrastructure; on the other hand, there arises a requirement for greater involvement on the part of the client in the security of his data.
What are the main security challenges of primary clouds?
There are numerous security challenges in the cloud or heightened relative to their on-premises counterparts. These include:
- Traffic Filtering, Monitoring, and Blocking: WAFs play a vital role in cloud security and in handling the humongous volume of traffic from various cloud applications. Failure to screen this traffic could result in it transmitting malware and requests from malicious bots.
- Protection of APIs: The numerous cloud APIs connecting to other services may result in costly data breaches if improperly protected and allow unauthorized data transfer.
- Bot identification and management: Botnets are responsible for numerous automated cyberattacks and, therefore, require proper identification and management to avoid issues like brute-force login attempts.
- Malware, APTs, and cyberattacks: The public accessibility of the cloud computing stack exposes it to constant and widespread pressure from various cybersecurity threats, which may cause access disruptions and compromise sensitive information. Thus, it is one of the fundamental cloud security risks.
- Inadequate or ill-defined security measures in cloud security controls: The failure of companies to update security controls that are necessary while migrating applications into the cloud is one of the common reasons, and this can cause problems relating to the lack of proper security.
- Misconfiguration: Incorrect configurations of cloud resources can go unnoticed for an extended period before a security breach occurs.
- Network/WAN security: The transition from the MPLS WAN architecture through SD-WAN to support cloud applications mandates adopting new security mechanisms and architectures like Secure Access Service Edge (SASE) for secure access to Software as a Service (SaaS) and replacing the traditional centralized security model of WANs.
Top AWS Services for Cloud Security
#1 AWS Identity and Access Management (IAM)
AWS Identity and Access Management (IAM) refines precise access control, helping to set permissions to determine who can access which AWS resources and under what conditions. Use this fine-grained access control to protect AWS resources while targeting the principle of least privilege.
- How it works: To define access permissions to AWS resources, IAM policies do it. These policies can be attached to IAM roles in the account or to specific AWS resources. When a request is made by a client to AWS, IAM evaluates this request against the policies and either permits or denies it. The “Understanding how IAM works” section in the IAM User Guide should be referred to for more details.
- The IAM Policy Language: IAM uses a policy language known as JSON to enable users to precisely state their access requirements using actions, resources, and conditions specified in policies. For more insights, see the IAM JSON policy reference.
- Types of Policies for Access: IAM offers the flexibility to apply policies to both IAM roles and the AWS resources supporting resource-based policies. Identity-based policies and resource-based policies collaborate in defining access control. Visit the “Policies and permissions in IAM” section of the IAM User Guide for more information about the policy types.
- Preventive guardrails: Preventive guardrails allow for the establishment of boundaries for maximum permissions in IAM roles. Service control policies, permissions boundaries, and session policies can be utilized to control the permissions assigned to an IAM role. To learn more about establishing a preventive guardrail, look at the “Data perimeters on AWS” resource.
