Today’s modern applications are designed for scale and performance. To achieve this performance, many of these deployments are hosted on public cloud platforms like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) for their benefit of elasticity and speed of deployment. The challenge is that effectively securing cloud hosted applications to date has been difficult. There are many high-profile security events involving successful attacks on cloud-hosted applications in the media, and these are only the examples that were disclosed to the public.
In reality, traditional security deployment patterns do not work effectively with applications hosted on public cloud platforms. Organizations should not try to push their previous on-premises application security deployments into cloud environments for several reasons.
Cloud application security requires new approaches, policies, configurations, and strategies that both allow organizations to address business needs and security risks in unison. Not incorporating these will no doubt deliver an insufficient security posture and cost unnecessary time and money.
The balance of performance and security
Whether your organization is a one-person startup, a global enterprise, or anything in between, you depend on applications to operate effectively. You cannot afford down time with these applications, and for many the cloud is still a confusing space when it comes to who is responsible for security. Unfortunately, a single unpatched vulnerability in an application can let an attacker penetrate your network, steal or compromise your data along with that of your customers—causing significant disruption to your operations. According to a recent report, “Unlocking the Public Cloud,”74 percent of respondents stated that security concerns restrict their organization’s migration to public cloud. Public cloud adoption is rapidly growing, yet security is the largest area of resistance when moving to the cloud.
Many organizations still rank performance well over security, but they should be in a balance with equal importance given the risks. For example, in a May 2018 report from Ponemon Institute, 48 percent of the 1,400 IT professionals who responded said they value application performance and speed over security.
While deploying layer 7 protections is extremely paramount to securing applications, it’s also essential that any security technology integrates deeply with existing cloud platforms and licensing models.
Security measures should be deeply coupled with the dynamic scalability of public cloud providers such as AWS, Azure and GCP, ensuring that performance handling requirements are addressed in real-time without any manual interventions. Also, organizations should direct access to the native logging and reporting features available to cloud platforms.
Fixing application vulnerabilities in the cloud
You wouldn’t necessarily think this, but application vulnerabilities are pervasive and often untouched until it is too late. Unfortunately, fixes or patches are a reactive process that leaves vulnerabilities exposed for far too long (months isn’t uncommon). The problem is clear and vulnerability remediation on an automated and continuous basis is paramount in ensuring application security both on-premise and in the cloud.
In reference to the Ponemon research, 75 percent of organizations experienced a material cyber-attack or data breach within the last year due to a compromised application. Interestingly, only 25 percent of these IT professionals say their organization is making a significant investment in solutions to prevent application attacks despite the awareness of the negative impact of malicious activity.
Because of frightening statistics like these, it is essential to implement a set of policies that provide continued protection of applications with regular vulnerability management and remediation practices, which can even be automated to ensure that application changes don’t open up vulnerabilities.
Security aligned with the cloud
Here are some best practices for effective application security in a cloud generation:
Basically, securing applications effectively in the cloud means adopting new ways of thinking about security, and it is critical to look at the security technology stack you have deployed today. Assess what is lacking and adopt what is required for regular monitoring and vulnerability remediation on those applications. It is key to focus on protecting each application with the right level of security. This means deploying security that is aligned with your current cloud consumption and leveraging tools designed for those cloud environments that allow you to build security controls.
