We are living in the technological era and our digital world is under an onslaught of cybercriminals. As digital transformation is becoming the need of the hour for every business organization, the magnitude of cyberattacks have expanded around the globe. Cybercriminals and attackers have taken great advantage of the lack of robust security frameworks and are growing into more sophisticated forms to infiltrate malware and automate attacks.
In the state of massive cyber-flux, business organizations are moving away from conventional systems to cloud systems for secured data storage. The outbreak of the pandemic has made every organization realize the pressing need to be resilient in their data infrastructures. It has shown how quickly tools can be deployed to prevent economic disruption and financial loss culminating from sophisticated cyberattacks.
There is no denial of the fact that cybersecurity gaps are abounding. India has witnessed 18 million cyber-attacks and 200,000 threats a day in the first quarter of 2022, as per recent stats. This creates a panic on both the industry as well as organizations’ front to protect cyberspace. With the establishment of disruptive cybersecurity solutions, three strong pillars have emerged to decrease the digital risk ecosystem.
Security by Design
The methodology is the initiation of any risk management in cyberspace that has genesis in the building blocks of the entire IT infrastructure design. It automates the data security controls of an organization and adds robustness to the IT infrastructure by implementing security protocols.
Gone are the days when organizations used to adopt reactive approaches i.e. managing the damage.
Security by design allows cybersecurity professionals to focus on a proactive approach and spend efforts on building a robust cybersecurity infrastructure right from the initial stage itself. The methodology ensures that risks are monitored and managed on a continuous timeline while prioritising and addressing new risks.
The Security by Design methodology is based on a few principles that provide stringent security to the product. The principle of attack surface reduction limits the user access to core functions and features of a product which limits the entry points to a web channel that are vulnerable to cyber breaches. In addition, the principle of least privilege limits the authority of the user, keeping the entire infrastructure safe. Furthermore, the principle of secure defaults sets the preferences of the users like characters required for passwords, two-way authentication and captcha verification.
Defence in Depth
Defence in Depth emphasises on providing holistic protection in cyberspace. It adds multiple layers of security to reduce vulnerabilities, threats and mitigate risks. Simply put, the multiple layers of security in the methodology provide extra protection as risk can be contained in the next layer of defence if one actor breaches the first layer. It is sometimes also referred to as a security in-depth strategy that covers people, technology and operations for holistic protection.
In the cybersecurity community, defence in depth is considered an important principle that strengthens the security architecture. It is significantly applied to industrial control systems, cloud services, sensitive data and many other domains for holistic protection. With multiple layers of security, the principle is ideally deep that minimizes the path for cyberattacks to enter space.
The principle is an expanded form of cybersecurity paradigms that focuses on users, assets and resources for protection. It authenticates, authorises and validates all users whether in or outside the organization’s network for security configuration. In modern day digital transformation, this principle works as a sound framework for securing the infrastructure.
The framework works on the assumption – there is no trust granted to assets or user accounts based on their physical or network location. It secures remote work models, hybrid cloud environments and ransomware threats. Recognised as the next-gen security framework, it involves risk-based multi-factor authentication and identity protection enabling system security maintenance. It requires organizations to constantly monitor and validate users and their devices.
Alignment is the key – when Security by Design, Defence in Depth and Zero Trust are combined together, they create a more robust cybersecurity infrastructure. On one hand, Security by Design monitors and manages the security process, the layers of Defence in Depth deter data breaches while Zero Trust protects assets, services, workflows and network accounts. These pillars need not stand alone and combined to create a strategy to overcome expanding cyberattack surfaces.
