Traditionally, companies have tried to keep every possible cyber threat outside and to protect themselves through the use of network security platforms such as firewalls. But now, this strategy has backfired because it restricts innovation.

It’s all too easy for an attacker to find vulnerabilities in an unprotected system- so you need a firewall that can protect against attacks. But when the protocol used is encrypted, how do you know where it came from? Traditional firewalls just don’t work anymore; they’re unable to scan encrypted traffic because it looks like gibberish! So hackers are using these new (and dangerous) ways of getting through- even if they cross into multiple networks.

While old-fashioned security guards like firewalls and Intrusion Prevention Systems (IPS) still work as barriers within a traditional network, they’re increasingly inefficient in today’s modern cloud and distributed networks. This is because the old model of network security relied on the assumption that most traffic passed through – going from south towards monolithic service pods – rather than branching outwards across the data center. It was also based on the idea that only enterprise-owned facilities would serve our services; while it didn’t factor in self-hosted infrastructure or third-party providers.

In recent years, the world of technology has seen a new kind of evolution in terms of what we call ‘application architecture’. This is due to many factors, such as the implementation of highly automated cloud and hosted data centres which have been built from different levels of virtualization – including containerisation and smaller service arrangements. These trends have led to an increase in communication between different software programs in both privately held networks, such as those running within or among private data centres or public networks across the internet which may lead to less visibility for those trying to manage them.

To protect these modern Application Architectures from East – West Attacks and threats, businesses need to have security policies be accessible from automated and orchestrated tooling to ensure safety for its employees. With old-fashioned methods such as conventional Network Security Tools, this task seems impossible. However, with the increase of Configuration APIs or programming interfaces meant for the Company’s needs and moving towards an SDN system; companies are succeeding in implementing new services quicker than ever before.

To protect these modern application architectures we need to be able to apply security policy in a way that is seamless with the enterprise’s automation and orchestration tools. However, conventional network security tools are incompatible with these systems – even though vendors are making improvements through features such as configuration APIs (application programming interfaces) and moving towards Software Defined Networking (SDN). This leads to delays in implementing new services, which creates unwanted obstacles when managing service infrastructures.

A traditional network security approach does not fulfill this requirement because it requires traffic to break out of the physical host at some point. Attempts to meet this requirement in the past have led to implementing complicated and fragile routing configurations that result in losing key advantages for virtualized networks. Workaround solutions were exploited by attackers resulting in persistence within a compromised network and enabling lateral movement within a service–something that micro-segmentation technology is explicitly designed to prevent.

A nice side effect of centralizing management of network security policy on workloads is through logging and other forms of telemetry, you are able to passively detect application data flows which gives you valuable information in high automated networks. With this, you can combine active application performance management systems so when changes happen, automatic adjustments happen too – dynamically adjusting network configurations and optimizing service delivery.

A large issue for many businesses today is how they can protect themselves from the latest in cybercrime while still being able to take advantage of all the benefits of cloud computing and virtual networks. Even if you’re just trying to keep things simple, without upgrading your system’s architecture or software, you will inevitably find yourself open to attack because traditional systems can’t support all the demands that come with using these new technologies.

To solve this problem, we recommend creating a computer network environment where all applications are segmented off from one another – which will leave them free from security breaches and potentially disastrous effects. And best of all, because everything is so well secured, you’ll finally have time to pay attention to what matters most: running your business!
