The DevOps Methodology
These days, most IT professionals are at least aware of if not familiar with the DevOps methodology. Merging IT ‘Development’ and ‘Operations’, DevOps promotes shared responsibility, continuous delivery and streamlined communication. It creates a seamless process for creating, maintaining and deploying new code - one which has proven demonstrably effective, efficient and lucrative in the ever-demanding world of IT.
However, ‘Dev’ and ‘Ops’ are hardly the only priorities in modern IT management. Developing security measures for new code and tackling security issues as they appear have become crucial points of focus in recent years. Coding is more important than ever, with many organizations releasing several updates every day. This has created much greater potential for leaving weak points which can either cause glitches or be exploited by hackers. These data security issues can put customers and stakeholders at risk, to say nothing of inviting significant penalties in the age of GDPR and compliance.
With traditional security strategies, testing is carried out towards the end of the code development cycle. Unfortunately, because most if not all code has been written by this point, having to make even minor edits can cause significant delays. This can create an expensive bottleneck just prior to the point of deployment. With security issues risking both major fines and serious blows to PR, attempting to rush through security testing in response to this can pose an even greater risk.
DevSecOps aims to improve this setup by integrating security into the continuous process espoused by DevOps. It inserts security considerations into code development from beginning to end, with stages such as Planning, Communication and Testing all taking security into account. In applying the DevOps model to security, practitioners can significantly streamline key security processes while also boosting their efficiency, value and reliability.
How Does DevSecOps Work?
DevSecOps involves practicing ‘security as code’. This essentially refers to treating security as you would any other coding requirements. There are six core elements to this:
Code analysis - Create code in small chunks to ease the process of searching for potential vulnerabilities
Change management - Allow anyone to suggest potential changes and assess each proposal. This will help to boost your speed and efficiency
Compliance monitoring - Treat compliance auditing as an ongoing concern. As part of mandatory regulations like GDPR, organizations must demonstrate what they have been doing, not just what they are planning to do. Continually collecting data will prepare you to demonstrate your compliance in the event that you are audited
Threat investigation - Be sure to treat every code update as a trigger to begin searching for, identifying and responding to threats. This should always be a part of your itinerary
Vulnerability assessment - Utilise code analysis to check for vulnerabilities. You can then analyze them to determine how quickly they should be responded to and patched
Security training - Ensure that IT and software engineers are trained in security according to strict guidelines and routines
When people discuss the ins and outs of DevSecOps, they often bring up ‘Rugged DevOps’. This is quite similar to DevSecOps, in that it deals with security considerations. However, it also has a much greater emphasis on vigilance and discipline.
‘Ruggedizing’ refers to making security a higher priority. It involves regular threat assessments, adding more tests to automated processes, and so on. In short, it is extremely similar to DevSecOps, with one of the only differences being the higher emphasis on priority.
As the Rugged Manifesto puts it:
“I am rugged because I refuse to be a source of vulnerability or weakness.”
“I am rugged because I assure my code will support its mission.”
“I recognize that my code will be attacked by talented and persistent adversaries who threaten our physical, economic, and national security.”
How can Getting Certified in DevSecOps Help my Business?
DevSecOps training can offer several potential advantages to an organization. While becoming certified is not strictly necessary for becoming a DevSecOps engineer, learning with an accredited course is one of the most efficient ways to gain the knowledge and skills required for the role.
Following DevSecOps removes the bottleneck of traditional security controls. Its streamlined and continuous process can ensure that development is kept on schedule, allowing practitioners to avoid missing deadlines and respond to flaws or glitches as quickly as possible. Remember, delays do more than just annoy customers; if they concern significant security threats, responding too slowly can be disastrous.
Because security is addressed throughout the DevSecOps development process, issues can be found quickly. This is crucial, as if unnoticed problems are buried in subsequent code, they can require far more editing to solve down the line.
In finding and dealing with problems at a faster rate, DevSecOps practitioners can also free up time and assets to be used elsewhere, such as adding features or training staff. This benefit is also linked to one of the key pillars of DevOps: greater automation. By utilizing the right open source automation software, practitioners can make security checks not only more efficient but also more reliable.
Another big advantage of DevSecOps, as well as DevOps in general, is that it can create a more constructive working environment. As part of the methodology, communication, collaboration and shared responsibility are encouraged. This ensures that issues can be responded to and resolved more quickly, while also creating opportunities for coworkers with different experience to share unique insight and ideas.
In conclusion, by applying DevSecOps tools and processes to a development lifecycle, practitioners can guarantee better ROIs both for security investments and deployed codes. Remember, security and compliance are not simply matters of following regulations; they can also create opportunities to boost the overall value of your products and services, to say nothing of giving you an excellent way to stand out from the competition.
