Architecture for XaaS Security in the Cloud

Cloud security architecture: What is it?

It is necessary to have a cloud security architecture in place. Prior to developing policies and solutions to avoid and mitigate risks, a company should examine its current cloud security posture. Enterprises and individuals alike may use untrusted personal and corporate devices to access a wide range of cloud-based and on-premises resources.

Why do you need this Architecture?

Prioritizing security is essential as more and more companies rely on the cloud for their operations. There is a lot of off-network data that passes through cloud services that aren’t properly protected. Businesses find it difficult to monitor and control data flows due to the proliferation of personal devices and cloud computing. Network security protections are bypassed when working together in the cloud. Unmanaged devices storing private data pose a security risk. Security and risk management experts have a difficult time keeping track of the myriad devices, networks, and clouds that exist today. Attackers are enticed to attempt a breach by these security mosaics. Many common internal security measures don’t translate well to the public cloud. Because of this, businesses must treat cloud security as a new issue and create a cloud security architecture to adequately protect this complicated environment.

Patterns of cloud security architecture

Your company’s security can be improved with the correct pattern. It can help you protect the confidentiality, integrity, and availability (CIA) of your cloud data assets and respond to threats. You have the option of implementing your own security measures or relying on third-party services or the services of your cloud provider. What else compromises it? 

  • Controls for security—technologies and processes—are frequently included in the cloud security architecture paradigm. Controls should take into account the location of the service provider (business, cloud, or third party).
  • Trust boundaries between cloud services and their components
  • Security protocols like SSL, IPSEC, SFTP, LDAPS, SCP, SAML, OAuth, etc.).
  • Management of tokens: techniques of authentication and authorization
  • AES, Triple DES, RSA, and Blowfish are some of the most popular algorithms, some of which has a key length of 128 bits.
  • Capturing and prioritising security events and sending them to the appropriate security personnel.

The following attributes should be used to describe each security measure:

  • What is the purpose of the service? like authentication, encryption, and the collection of event data.
  • Location can be in the public cloud, with a third party, or on-site. The management and performance of services are influenced by geographical considerations.
  • Using what method, for example, do you get to the service? SSH, HTTPS, and REST
  • What is sent to and received by the service?
  • Mechanisms of control—how does the service keep things under control? Authentication of users, programmes, and data in a persistent state.
  • Who is it that makes use of or gains from this service? It includes endpoints as well as users, business leaders, and security analysts.


Models for securing the cloud (IaaS, PaaS, and SaaS)

All the above have different cloud security architectures (part of Anything as a Service, XaaS). The following is a list of security concerns for each of the models listed.

Architecture of IaaS Cloud Security in the Cloud

Cloud storage and network resources are provided through IaaS. The cloud is largely controlled and operated through APIs. Openness and web accessibility make cloud APIs vulnerable. The cloud service provider (CSP) protects both the infrastructure and the abstraction layer from external threats. It is your responsibility to protect the layers that contain your company’s business applications. A network packet broker (NPB) can help you better comprehend the security threats of cloud computing. The NPB serves as a conduit for information to be routed to the NPM and its associated security tools. Set up a log of network events for each endpoint. Infrastructure as a Service clouds must adhere to the following security measures:

  • Configuring network segmentation
  • Detection and Prevention of Intrusions
  • The cloud network’s perimeter is guarded by virtual firewalls.
  • Routers (Virtual)

Architecture of SaaS Cloud Security in the Cloud

Web-based access to applications and data is made possible through the SaaS cloud security architecture. Security responsibilities vary from service to service and are sometimes negotiable. Using CASB (Cloud Access Security Brokers)’ logging, auditing, access control, and encryption, SaaS goods can be traced back to any security issues they may have. Make certain that your SaaS environment also has: API gateways, if a service is accessible through an API; IP whitelists/blacklists; alerts. 

Architecture of PaaS Cloud Security in the Cloud

Platforms as a Service (PaaS) make it easier for businesses to develop apps by removing the need to maintain hardware and back-end software. The PaaS model of the CSP protects the environment. However, the company is still in control of app protection. As a result, the security of PaaS is the same as that of SaaS. CASP, logging and alerting, IP limitations, and an API gateway are all effective methods for ensuring that APIs both within and outside your company are protected.
