Application Modernization: The Security Implications of Linking Old and New

At a time when digital transformation has become central to business, even the most important applications come with an expiration date. Left unchecked, legacy code within these applications can become a bottleneck over time, limiting DevOps teams whose job it is to innovate.

Legacy monolithic local applications are based on older and limited frameworks, software libraries, and operating systems. This creates side issues when deploying these applications with newer software architectures and forces DevOps to spend resources trying to integrate and understand legacy code. Legacy applications are also more likely to suffer from the kind of security issues that can be difficult to mitigate.

The Benefits of Application Modernization

Application modernization is an approach that allows organizations to overcome these problems without simply abandoning applications entirely, updating enough code to bridge the old and the new.

Through application modernization, organizations can enhance existing applications by integrating them with newer frameworks and infrastructure platforms. This makes it possible to protect existing investment while upgrading your software portfolios across the business environment. Since everything from initial software development to customer experience depends on data integrity and efficiency, modernizing legacy applications helps improve data quality across all workflows. Organizations can mitigate bottlenecks arising from legacy systems, which almost always compromise new projects.

Some of the benefits of application modernization include:

  • business agility – makes it possible to add new functions, services and infrastructure support in the cloud
  • cost reduction– eliminates unused or redundant features to save costs, allowing more investment in innovation instead of legacy management
  • Enhanced Security – integrates new security features that reduce the possibility of data or system compromise
  • Improved performance – accelerates legacy applications across the enterprise
  • user experience – enhances applications with more advanced features that improve the customer experience
  • Maintenance – Reduces the burden of caring for legacy applications, which become more expensive over time

Key Technologies for Application Modernization

Before embarking on application modernization, organizations should first consider how best to integrate this with a variety of cloud infrastructures.

  • Cloud computing (public, private, multi-cloud and hybrid cloud) . As more applications transform from the traditional data center to a public, private, or multi-cloud environment, not all organizations can go directly to the cloud. A hybrid approach may be required as part of this journey.
  • containers they are a cloud-centric method for packaging, deploying, and operating applications and workloads, providing greater scalability, portability, and operational efficiency that fits well with cloud infrastructure. They are especially useful in multi-cloud and hybrid environments.
  • microservicesthey are less a technology than an architectural choice. Instead of building and operating an application as a single, complete code base, often called a monolith or monolithic development, components are decoupled into smaller pieces that are independently deployed, updated, and operated.
  • Orchestration and automationin software development it refers to the automation of many of the operational tasks associated with containers, including deployment, scaling, and networking. Automation is an important principle and is increasingly necessary to ensure that development, operations, and security teams can manage their modern applications at scale.

Any technological review carries risks. And while cloud adoption has many benefits, it also creates uncertainties that are top of mind for seasoned CISOs. These include:

The growing threat landscape

Attackers are becoming more active across all threat types, with more DDoS attacks targeting infrastructure, applications, and business layers. As organizations migrate their applications to the public cloud, hackers are increasingly targeting public cloud infrastructure. In this threat landscape, it is clear that only the most advanced security will protect critical business infrastructure.

Accelerated digital transformation

As more applications are brought online, the speed at which organizations develop and introduce new applications becomes a source of competitive advantage. To keep up, organizations must ensure that their DevOps efforts are faster and more agile as a way to maintain the business transformation that management demands. To avoid additional cyber risks, security must be tightly integrated with the development process.

New application infrastructure

Modernizing applications that use containers and microservices requires new tools that must be protected. Additionally, accelerating the pace of development requires security that fits with existing processes and DevOps frameworks.

The Radware Solution: Frictionless Security

The gradual aging of legacy software applications is an issue that eventually needs to be addressed in all organizations. But the risks that this implies in terms of cloud migration and service availability remain a huge barrier. While legacy applications have limitations, they are predictable and familiar. Redesigning them to work in cloud environments opens organizations up to unknown levels of exposure and risk in terms of security and availability.

Radware solutions address these challenges on several fronts. Our next-generation DDoS protection protects an organization’s infrastructure from the most advanced threats, and our Application Delivery Controllers (ADCs) keep applications available and secure. Meanwhile, Radware’s advanced web application firewalls and bot management solutions protect applications and data from attacks and compromises.

Radware protects the transition to the cloud with our Cloud Native Protector for workloads and our advanced and flexible Alteon Global Elastic License. The single license model allows organizations to decide how best to use a single capacity license to shift and scale workloads and capacity across any private data center or public and private cloud, regardless of location or the type.

It’s through Radware’s frictionless security that critical applications can be protected without security getting in the way or creating management overhead.
