Anthony Webb, Vice President International at A10 Networks, tells us how combining application delivery with next-gen WAF is crucial for enhancing cloud defence and building resilience in hybrid cloud environments.
In today’s modern business landscape, outside of any macro issues or economic uncertainty, enterprises have two significant technology challenges. The first challenge is around the constantly evolving threat landscape, and the growing sophistication of cybercriminals and their techniques. This means the risk of an application attack and a data breach is an ever-present threat that enterprises must contend with.
The other key challenge is around the effectiveness and economics of cloud operating models. Without a doubt, over the last decade, Digital Transformation has catapulted many businesses forward, many of whom can now claim to be ‘true’ digital businesses servicing their customers in new and exciting ways. However, in this new digital and hybrid cloud environment, enterprises are highly concerned about how they can best secure, optimise, and automate their infrastructure in the most effective and cost-efficient way.
Applications must be consistently available
Today, organisations have to guarantee their applications are consistently and securely accessible, no matter the location, to ensure the best end-user experience and productivity. This includes ensuring workloads are efficiently distributed across all servers, monitoring application health, and maintaining operational integrity around the clock. However, when you add in the need to protect against a rise in application attacks and an ever-increasing number of bad actors targeting the organisation, the scale of these challenges starts to become clearer. Likewise, complex deployments coupled with regular maintenance and often limited resources dedicated to cybersecurity are exacerbating the risk to organisations further.
In this environment, with cybercriminals constantly evolving their tactics to exploit vulnerabilities in systems, a layered defence strategy that provides comprehensive protection against a wide range of threats is essential. At the same time, a solution that also helps to deliver better business outcomes, enabling organisations to optimise the customer experience, and ensure business continuity, is highly desirable.
Combining ADC with next-gen web application firewall
Combining an application delivery controller (ADC) and a next-gen web application firewall (WAF) creates a robust security solution that supports the principles of a Zero Trust security framework. As organisations seek to establish a more efficient, effective, and secure cloud operating model, these two combined technologies enable a highly performant security solution at a strategic application ingress point that reduces false positives and automates security, empowering agility and effectiveness. The ADC efficiently sifts through the myriad of threats, while the next-gen WAF efficiently provides defence against more sophisticated web attacks.
How does this layered defence approach work
To explain in a bit more detail how this layered defence works, let’s start with the ADC. ADCs can provide load balancing and transport layer security (TLS) offloading, which can help reduce the attack surface by minimising the number of entry points into the system. This mitigates the impact of volume-based attacks, such as DDoS or brute-force attacks. On the other hand, next-gen WAFs can provide deep packet inspection and advanced threat detection capabilities, enabling them to identify and block attacks such as account takeover (ATO), known CVEs, injections, cross-site scripting (XSS), and other OWASP Top 10 attacks.
Earlier in the year, we partnered with Fastly to offer its next-gen WAF with our Thunder ADCs to provide our customers with a premier next-generation web application firewall solution running on high-performance hardware and virtual platforms for businesses operating in a highly competitive market. This enables organisations to protect their apps against advanced threats with greater accuracy while gaining superior application availability and accelerating content delivery.
Digital Transformation initiatives will continue to evolve
Unfortunately, Digital Transformation is not a one and done initiative. Moving forward, enterprises will continue to evolve their environments as new technologies inevitably emerge. Likewise, the cyberthreat landscape will undoubtedly continue to expand, very likely at the same pace as we’re seeing currently—if not faster. Organisations must, therefore, stay vigilant, never compromise and make sure that they have a layered defence approach to protect their business.
