The Multi-Cloud Environment and Software-Defined Perimeter

Software-Defined Perimeter (SDP) is a significant step forward in security because it allows dynamic, identity-centered security to be implemented on the network layer for the first time. In addition, the organization will be pleased to discover that it is more comprehensive to fulfill contemporary security and commercial requirements.

Through an integrated security architecture approach, a software-defined perimeter (SDP) creates virtual barriers around Internet-connected assets and human behavior. Whether assets are on-premises or in the cloud, and whether users are on-site or working remotely, SDP works. Rather than depending on hardware at the network boundary, such as firewalls or VPNs, SDP uses software to block access to and visibility into resources within the virtual perimeter by default.

Cloud integration has many benefits, but it sometimes necessitates various adjustments to completely comprehend. This post will provide you with a different perspective on the cloud. You can also see how it may be improved to be safer and more efficient. Additionally, using those resources is cost-effective for users. Ideally, this post will assist you in comprehending the specific difficulties surrounding IaaS network access. Also, to learn how a software-defined perimeter can assist in resolving these issues.

SDPs offer access control to network-based services, systems, and software in public and/or private clouds and premises. Because the technology obscures it, the SDP cloud security approach is frequently referred to as a black cloud.  To prevent outsiders from following it, it was hidden within the perimeter.

Use Cases for Software-Defined Perimeters

Here are a few examples of how SDP cloud security can be used in the workplace:

  • Improved Bring Your Own Device (BYOD) Access

Access to cloud apps and resources is secure, rapid, and effective from a variety of devices.

  • Third-Party User Access with Benefits

Allow third parties from all over the world to gain access to critical systems. However, with the help of an application or resource, there is a higher level of reliability.

  • DevOps

Secure dynamic access gives DevOps users access to critical resources while also isolating them.

What Are The Most Important Factors For Decision-Makers When Adopting SDP?

It’s important to note that SDP is typically used to address a specific business need rather than to upgrade technology in response to this question. As a result, decision-makers should seek SDP-based solutions that meet business needs while retaining user transparency and ensuring compliance with security standards. In terms of technology, businesses should search for SDP technology that is simple to adopt, set up, and run.

Furthermore, SDP must first inspect and authenticate devices before providing reliable end-to-end communication. Endpoints and applications, as well as programs and services, are all accessible regardless of their location. This necessitates the use of a VPN and SDP. SDP should combine and continuously monitor the safety and regulatory compliance needs in a hybrid IT environment.

Given the length of the list, businesses should devote significant time to studying, assessing, and testing SDP technologies, as well as selecting solutions that meet current and future business, networking, and security requirements.

Conclusion

Many aspects of information security are simply outside the scope of SDP, and there are residual threats tied to a specific product or driven by corporate implementation details.

Owners should use their VPN infrastructure to enhance their SDP tools. They can collaborate on security issues such as hybrid and multi-cloud installations. Assist in reducing attack surfaces and securing sensitive data. For hybrid or multi-cloud systems, network administrator SDP software divides services for fine user access with the use of a highly available micro perimeter.

However, in general, the software-defined perimeter is a unique and appealing security technique.

Coronavirus Crisis | Impact, Sustenance and Security

The threat is real, and it is here. Crashing stock markets, disrupted supply chains, jolted travel industry, strained economies, and shut down factories, all these are results of the Coronavirus pandemic. Many economies around the world are struggling to contain the spread of Coronavirus, the hardest-hit countries being China, Italy, the US, Spain, Germany, and Iran. There are over 300,000 reported Coronavirus cases globally (according to WHO on 23 March 2020), since the virus first emerged in December 2019 in Wuhan, China. As the whole world is so interconnected, thanks to globalization, Coronavirus has spread to 117 countries in just over two months. It has become one of the greatest threats to the global economy and financial markets.

Being the manufacturing and exporting hub of the world, China holds a major contribution to the world’s GDP. So the economic turmoil in China due to Coronavirus is imperiling global growth. The impact of Coronavirus on the world’s economy and the fear of a global recession is shaking investor’s confidence and is rocking stock prices across countries. The global stock market has witnessed the most massive single-week decline post the financial crisis in 2008. With worldwide conferences, events, and sports around the world being canceled or postponed and travel restrictions being imposed by governments to curtail the spread of Coronavirus; the travel and tourism industry has been severely impacted. Other industries like retail, restaurants, entertainment, etc. have also started to bear the brunt of the pandemic.

Tough times such as this calls for tough measures from governments and organizations. Until vaccination or cure for the virus is available, the best way to curtail the virus from spreading is through social-distancing, which includes travel restrictions and avoiding large gatherings. Governments are imposing lockdowns and placing quarantine measures nationwide. Organizations are providing flexible working arrangements. Coronavirus has triggered the biggest work-from-home movement in history. To swift through the crisis, companies should also focus on effective communication, ensuring trust and disaster planning.

A majority of organizations are providing work from home options to their employees, cybersecurity has become an even bigger concern than before. While organizations are hurriedly implementing these changes, they are exposing themselves to more potential threats like compromised user credentials, organization’s data theft, and phishing attacks. For providing secured remote access, organizations should assess their existing security framework. Technologies like modern Network Access Control, Software Defined Perimeter, and other Zero Trust network access solutions will find more acceptance and witness a sharp growth in demand.

Decoding Zero Trust Security | Concept and various Models (Part-2)

The previous part of the blog talked about the concept of Zero Trust security, its relevance, and how it is catching traction in today’s time. This part talks about the different models to implement Zero Trust security in organizations. There are three different ways in which organizations can choose to implement Zero Trust security.

1. Software Defined Perimeter (SDP)

Software Defined Perimeter is an approach in network security that safeguards user access to applications and information irrespective of the location, time, and nature of the device used. Software Defined Perimeter follows a zero trust approach, wherein the network security posture is that of default deny. Access is granted upon authenticating and authorizing both user and device.

By making the applications and resources invisible and preauthorizing users and devices, SDP protects enterprise applications from a range of attacks like- denial of service, credential theft, server exploitation, connection hijacking, and APT/Lateral movement. Unlike the previous security models that worked till the network layer, SDP works right up to the application layer. It provides granular control on applications as users are allowed access only on authorized applications and not others.

2. Network Micro-Segmentation

Micro-segmentation or network Micro-segmentation is slicing the network into small logical segments and controlling access to applications and data on those segments. Diving the network into smaller segments reduces the attack surface for malicious attackers. Micro-segmentation policies are based on logical attributes or resource identity versus the user’s identity or IP addresses. Micro-segmentation creates an intelligent grouping of workloads based on their characteristics. It provides centralized dynamic policy management across networks, independent of the infrastructure.

3. Identity Aware Proxy (IAP)

IAP architecture offers access to applications through a cloud-based proxy. It follows the principle of least privileged access like SDP, but applications are accessed through standard HTTPS protocols at the application layer. Unlike SDP, which uses a direct tunnel for data transfer, IAP architecture provides authenticated and authorized secured access to particular applications using a proxy layer.

Google was the first one to implement zero-trust security architecture in their business using BeyondCorp, through an Identity Aware Proxy model. BeyondCorp is their internal network and access security platform designed for employees to access internal resources. BeyondCorp is a web proxy-based solution that supports HTTP, HTTPS, and SSH protocols. Following BeyondCorp, Google also launched Cloud Identity Aware Proxy for access control and protecting data in the cloud. Cloud IAP shifts access controls from the network perimeter to individual users.

Irrespective of whichever zero trust model companies choose to implement; it should be able to integrate with the company’s existing security infrastructure seamlessly.
