Today, as we see, the success of DevOps depends on both the cultural shift around like-minded people and the relevant process, as well as the technical implementation skills of the team across both Dev and Ops. DevOps has evolved as one of the most popular software development approaches in recent years. Every software professional in build and release engineering will probably have a strong desire to become a DevOps expert. Nevertheless, DevOps has created a good amount of influence on the mindsets and technology landscapes of software organizations to build cloud compatible amenities in a highly competitive market environment.

With DevOps in place, we can clearly see automation has become a more critical element than software development cycles with the introduction of languages like Python and Go languages. Even addressing legacy issues like updates, fixes, and patches to software application services gas become quite flexible easy with the help of DevOps tools.

Most organizations are trying to reach a state where they can comfortably say they have refined their DevOps best practices model. Instead, the recommendation would be to experiment with new processes, capabilities and tools identifying those that can yield the highest possible integration across the entire DevOps toolchain to deliver the best value for the business as well as for the organization.

Endpoint Detection Response

EDR is a cybersecurity technology that addresses the need for continuous monitoring and response to advanced threats. To be precise, while deploying applications or detecting the threat and executing preventive measures, intervention of humans is kept minimal.

EDR solutions were developed and promoted as the next step in defending the organization from various cyberattacks. Having rich various data collection and monitoring capabilities, EDR solutions allows organizations to detect and fix advanced threats before they can cause any significant damage. Today, according to various reports in Gartner, we see the EDR market is growing. Security breaches are more widespread than ever, and most enter networks via endpoints. EDR solutions offer an innovative approach to continuously monitor network endpoint devices for nasty activity and prevent attacks. Based on the pattern of attack, EDR helps to identify the trigger as the next course of action to address it. Predominantly, these solutions help to analyze endpoint data actively to provide detection and prevention in a real-time scenario.

EDR solutions also possess the capability to analyze the behavior of endpoints users and devices for suspicious activity and send corresponding alerts to the system.

EDR replaces the use of digital signatures to detect threats and provide behavior-based solutions for proactive security threat intelligence. All the processes of EDR solutions are mainly based on activities, events, and interactions on endpoints or with endpoints.

What Stands in The Way of DevOps?

Now, let’s try to understand encounters in DevOps. Over time, it is realized that security is unnoticed while moving to DevOps culture. Let us list a few of the challenges the DevOps approach might have today.

Environment Challenges

Any difference in the environment can certainly cause differences in both development and deployment aspects. Change management can play a significant role, bringing in consistency and addressing the challenges in the environment.

Open Source

Open-source projects are quite critical for any business operations. The DevOps approach has increased with major usage of open-source. Open-source software has moved away today from innovation side projects and part-time work, evolving into technology that's being adopted and maintained at an organizational level. With open-source projects in place, there is no doubt a team gets most of the time chunk of validated code fragments to enhance the functionality of particular applications. 

But a striking fact is that majority of cybersecurity applications are found as high-risk open source vulnerabilities. To encounter such experiments, the team should be well-read to understand open-source frameworks used in DevOps toolchain and top up information which keeps coming at good frequency. The team should also adapt themselves to fix bugs and apply patches as and when it becomes available. The use of listed repositories available in the market will be added advantage in the current scenario.

Security Management

One of the critical success factors is as simple as ensuring that the security parameter has a seat in your design framework when you are creating an overall strategy. From all perspectives, having security in place reduces risk and ensures compliance . Today, a long development cycle is the result of not bringing in and adopting best practices in coding. This can eventually happen due to a lack of awareness of security approaches and strategies while writing code and committing for the build. It would be a good practice to address it at the development phase of project by the team or organizations

Testing Framework

Reliable testing is one of the important criterias for a successful DevOps implementation. Today there are various automation tools available which increase the speed at which developers commit code and build an executable. However, the question is whether these tools allow the testing team to deep dive into various test scenarios and look into code coverage efficiently, as there are a good number of tools that show how code coverage percentage is lagging or needs improvement. With the advancement in methodologies from waterfall to Agile to DevOps, there are a lot of benefits of a robust framework.

Metrics and Monitoring Zone 

Once the product is delivered to the customer, addressing quality issues across multiple business lines is quite challenging. Such issues are seen OR caused by an undetected latency in the system. With my large experience in end-to-end system labs across a domain, what we have observed to an extent is that the services were only being monitored by an engineer if they were up or down based on color code, not if they were actually working, thanks to classical impressive GUI. Although the end-users could log into the application because it was up, they could not use it because it would hang or take too long to load. The team realized that for their DevOps practice to be successful at the customer end, they had to provide service which brings in value to the business. Metrics should be defined not only for the services, but also for the underlying systems and team members throughout the process. For example, understanding the velocity issues of your Scrum team can assist in identifying bottlenecks or critical skills gaps that will impact quality and agility.

EDR Integration With DevOps

DevSecOps is all about introducing and utilizing tools/solutions to secure continuous integration, development and delivery of applications. These applications made for services run at either server-side or at user/client devices. EDR solutions work actively in systems where endpoints have been contributed. EDR solutions can be integrated within the DevOps cycle, so nasty activity can be tracked and hunted down by developers. This can be the quickest and automated way to tackle security threats.

The public cloud provides an environment for developers for the development, testing, and execution of applications. The DevOps approach is mostly consumed by community cloud vendors with their set of supporting tools. But the cloud has its own security concerns—such as any misconfiguration or code fault in the application resulting in a huge attack. Also, cloud resources are mostly accessed by various types of devices which may/may not be secure. Some developers use their own devices for the development and monitoring of the application. EDR solutions can be recommended here by applying itself at endpoints as well as at public cloud infrastructure end.

To know EDR, the features that most integrate inside EDR solutions today should be well understood. Few of the features we see in the market includes:

  • Handling threat intelligence
  • Ability to detect and prevent hidden complex processes
  • Visibility throughout endpoints
  • Automation of specific alerts
  • Turning off specific processes when an attack is detected
  • Detect malicious activities and simplify security incident response
  • Forensic capabilities to minimize the impact of the breach
  • Data collection to build a repository used for analytics

Gartner has named a good number of vendors in terms of market share in one of its reports "Competitive Landscape: Endpoint Detection and Response Tools." This article also laid out the various required features for EDR solutions, one can investigate it to have deep understanding based on various vendor solutions.

Final Thoughts

Deploying an EDR solution doesn’t mean that the organization reduces its intrusion risk in any appreciable way. However, EDR solutions today are based on cutting edge technologies that generate actions based on analytics information provided by sources or endpoints. EDR tools integration with the DevOps toolchain takes automation in process execution at much beyond the level to track security breaches in run time and chase down vulnerabilities within code framework before the application just goes live. Not to forget, endpoint devices until today are always more significantly emerged in generating various security incidences. It has become essential for DevOps teams today to look after endpoint protection more and more in the coming days. Earlier is better.
