Design Approach in Cyber Security

Introduction

Today, most firms understand that to stay competitive and relevant, they must embrace new technologies and constantly innovate. However, in their drive to modernize their systems and operations, they introduce many vulnerabilities throughout their firm, exposing themselves to an increasing number of threats.

Meanwhile, with nearly unrestricted access to a myriad of software and services only a click away, there are always more would-be offenders eager to exploit these weaknesses. These threat actors are no longer just concerned with data theft for monetary gain, as they formerly were, and the number of politically motivated assaults has skyrocketed. Recognizing the inefficiencies, senior management leaders acknowledged the need for a new approach that would allow them to develop effectively while also minimizing and managing the risks associated with cyber-attacks. Security by design is a comprehensive, strategic, and practical strategy that analyses risks and security from the start of a program or product rather than adding it afterward. It fosters trust at every level.

What is Design Approach in Cyber Security

Security by design also, known as secure by design, is a method of developing products that address Cyber security from the start. It’s like constructing a house and ensuring it’s an earthquake- and windstorm or typhoon-proof.

Security by design guarantees that security protections are incorporated into the design of a product rather than being added as an afterthought. This strategy has become prevalent in product development since it decreases the possibility of Cyber security breaches.

Security through design applies to any software and hardware. The method includes popular cybersecurity methods and approaches into the architectural design process. If the system is attacked, these approaches ensure that the essential security policies or processes are implemented. These procedures must at the very least include:

  • Authorization and accountability: Only authorized users have access to particular system areas, which clarifies accountability.
  • Authentication: All users must go through the authentication procedure regardless of their rights.
  • Data confidentiality and availability: Data is kept secure, private, and only available to authorized users when required.
  • System integrity: Unauthorized users cannot tamper with data or the system as a whole.

Including these protocols into the architectural design will continue to be executed even if goods undergo many alterations.

Advantages of Security by Design

In addition to data security, Security By Design provides the following benefits to organizations:

  • As new apps and products are developed, Security By Design assists enterprises in safeguarding connected devices, sensitive and personal data.
  • With the aid of Security by Design, organizations may detect existing vulnerabilities and security gaps early on, avoiding problems that could have arisen later.
  • It boosts businesses’ faith in their systems, data, and information, allowing them to embark on creative projects boldly.
  • Security by design allows companies to adjust systems or configurations only when necessary changes, rather than with every little modification.

Principles of Security of Design

The following are a list of Security of Design principles that, if implemented, will assist enterprises in securing their applications and considerably lowering the probability of a successful cyber-attack:

Reduce the assault surface area.

Every time a programmer adds a new feature to an application, the likelihood of a security vulnerability grows. To decrease possible vulnerabilities, the notion of reducing attack surface area limits the functionalities that users are authorized to access. The programmer should design the application such that access to features is restricted to registered users, decreasing the attack surface and the chance of a successful assault.

Offering the least privilege

Users should only have the power needed to execute a certain task. For example, if a person is just meant to make minor changes to a website, that individual should not be granted administrator privileges such as adding and deleting people.

Validate the inputs

Every field should only accept characters/numbers that fulfill the requirements. Disregarding anything that the field should allow, will aid in preventing cyber-attacks.

Distinctive systems

Following an assault, hackers go from one system to another. As a result, systems should be kept distinct from one another. For example, the webserver and database should be on distinct systems so that if a web server is compromised, the attacker is still a long distance away from the database.

Data that is confidential should be encrypted.

With data increasingly being kept on the cloud, enterprises no longer have complete control over data storage and processing. As a result, it is critical to encrypt any private data so that even if the hacker gains access to the system, he cannot read the encrypted data.

Regularly update and test

Systems must be updated with the most recent versions to solve security flaws in previous versions. Security checks must be performed on systems to assess their Security and susceptibility.

Depth of defense

This strategy combines many methods for making a product secure from a security standpoint. For example, while transferring funds, many banking websites require users to provide their login credentials and the one-time pin issued to their mobile device. An IP address verification and brute-force detection are also included in the payment transfer procedure.

Third-party Services should not be relied upon.

Web applications that rely on third-party services for enhanced effectiveness should always verify the information these services supply and should not grant these services high-level access within the application.

Maintain a minimal security system.

When designing security measures for the application, the architecture should be straightforward. When problems arise in complex systems, they are difficult to repair, and debugging may be time-consuming, providing a chance for hackers to exploit, putting the application in danger.

Conclusion

The form of cyberattacks varies and changes regularly, encompassing hardware and data breaches and software damage. To escape the attack, you must recognize that one solution does not fit all cybersecurity. To improve cybersecurity, you must also explore beyond the conventional antivirus software and downloaded firewalls. To stay ahead of hackers, you need the services capable of continually devising new strategies and tweaking existing ones.

This requires security to be integrated into goods from the start rather than an afterthought. To know more about the Security By design approach, get a cyber security certification online program at Great Learning.
