India’s Content Delivery Network (CDN) market is growing at a CAGR of 25%, to USD 5,879 million, by 2030. We are not surprised by these projections from coherent market research, as enterprises depend on cloud solutions to deliver high-performance digital experiences.
Edge safety is a top priority
Simply defined, CDNs are networks of geographically distributed servers that facilitate content distribution and content delivery to users. They offer the basic infrastructure across networks that reduce the latency of loading web page content and provide noticeably improved speed and user experience.
With the reliance on applications and business processes running properly over the Internet, it is now essential to prepare for the security breach that will occur. Your alternatives are data theft, reduced bandwidth, slow speed, data corruption, outages – all of which threaten the stability of your business.
If you’re operating in the cloud today, then CDN and application security must be part of your overall strategy and brand value. You will need to understand how to meet the needs and ensure the safety of your customers as they interact with your online services.
Unpacking risk and vulnerability
Breaches are propagated through smart adaptations delivered through cloud infrastructure. Let’s take a closer look at some compromises and attacks that can shut down access immediately.
- Blocked location – Researchers have found a bug where error pages block access to working websites. Hoai Viet Nguyen and researchers* discovered how cache poisoned denial of service (CPDoS) occurs by manipulating the CDN into caching the error page.
- Web traffic – In addition, hackers can exploit HTTP packets to increase web traffic and deface websites. This type of DDoS attack exploits incorrect HTTP scope request implementations.
- IP Assault – A direct attack is another attack where hackers target an IP address. This network attack can disrupt all the applications that reside on the server.
Companies should be aware of these dynamic data vulnerabilities. Weaknesses can be exploited by high traffic with randomly configured queries.
It’s time to mitigate risk
Start by adopting a multi-pronged approach to mitigating CDN vulnerabilities on your domain and website. Don’t forget to turn on the appropriate Secure Sockets Layer (SSL) or Transport Layer Security (TLS) encryption along with specialized encryption hardware.
Essentially, TLS serves as a protocol for encrypting data sent over the Internet. It evolved from SSL, the first widely used encryption protocol on the web, and reinforces proper encryption practices — thus ensuring that attackers cannot access critical data.
Around that, web application and service API protection (VAAP) they represent a barrier between the wider Internet and the actual content of the organization. They monitor and block malicious http(s) traffic that poses a security threat. At the same time, VAAP analyzes HTTP/HTTPS traffic, ensuring that action will be taken whenever malicious traffic is detected.
Depending on the company’s CDN provider, it is important to opt for website security scan for hacks and blacklistsDDoS protection, blacklist removal and load balancing.
The most important thing is to ask questions about how your CDN provider caches data and where that data resides, to prevent vulnerabilities.
Be proactive in protecting your CDN usage
To ensure that CDN solutions can be effectively utilized, organizational leaders must be interested in conducting due diligence and research on best practices and how their CDN would fit their static and dynamic content usage.
Security isn’t just something you should take lightly. Fortunately, there are ready-to-use analytics and security testing tools available to work in-house or through outsourcing. Following security best practices will allow you and your CDN provider to provide the most reliable, satisfying services to your customers – who matter most.
