Software is at the heart of most modern systems and plays a crucial role in every aspect of our lives, from banking and finance to healthcare and transportation. As a result, developing and maintaining software that is scalable and dependable is essential. Software security is also critical in light of the rise in cyberattacks and data breaches.
This is where the National Cybersecurity Strategy, which was unveiled earlier this year and focuses on improving national resilience and cybersecurity, comes into play. In particular, strategic objective 3.3, which is titled “Shift Liability for Insecure Software Products and Services,” emphasizes the requirement for safe and dependable software systems that are able to withstand cyberattacks and other threats and hold software vendors accountable for failures.
There are some lessons from common software development practices like modularization that may also apply to a more secure cryptographic infrastructure in light of this and the possibility of future legislation that would “establish higher standards of care for software in specific high-risk scenarios.” These lessons may become crucial to the success and even the survival of software companies, which are currently only at risk of their reputations because they produce insecure products.
Software is broken down into smaller, easier-to-manage modules called modularization. It is easier to find and fix bugs, add new features, and scale the system because each module can be developed, tested, and maintained independently. Therefore, software development companies are of utmost importance.
Database and storage systems’ security and reliability are also enhanced by modularization. Security access control is made explicit by interfaces between software modules that are clearly defined. Security is improved and confusion is reduced with explicit access controls. Additionally, because individual modules can be restarted or replaced without affecting the system as a whole, modularization can make it simpler to recover from system failures.
Encryption is typically incorporated into the transport layer and compiled directly into the application, in contrast to typical agile practices. In a similar vein, router stack security cannot function without IPSEC and MACSEC. Recompilation of these software applications is required whenever cryptographic algorithms are updated.
Database storage, on the other hand, is correctly modularized and uses well-defined APIs like SQL. Any database on the backend will function with an application that can utilise SQL commands like “store this” and “retrieve that.” If specific performance traits from a specific database turn out to be undesired, you don’t have to rewrite and relaunch the programme as a whole. The database is easily replaceable.
Additionally, a storage subsystem that consists of disks each with its own modularized interface for storing and retrieving data in blocks lies beneath the database. The database can be used with any storage subsystem. Storage redundancy can be simply driven by policy by IT, regardless of the database that runs on it. In a cloud-first world where parts and components of applications can all be in various stages of development, each with its own road map, this modularization is the foundation of agile software design. Agile software development companies is very important to acquire cryptographic flexibility.
Through a clearly defined API, each modular component provides a “service” to the components that use it, and each component can use its own underlying components through a specific API. As long as the service they provide to other components remains accurate and dependable, components can be upgraded, updated, and changed independently.
Encryption must teach a similar lesson. From “Hand me a symmetric key” to “Encrypt this data block,” one might envision one or more straightforward APIs. Algorithms and keys can be changed at runtime without affecting the application’s performance or security because the application is no longer directly concerned with encrypting the data.
We can easily implement this through a policy as we progress through various encryption standards, further hardening of keys, and even adding redundancy to the cryptographic chain. The app simply makes use of the APIs that are provided to it and is completely unaware of this.
A degree of adaptability and flexibility to changing security threats would be provided if software purchasers had the ability to swap out encryption algorithms in the event that one were compromised. Users could easily manage new security measures and algorithms to guard against emerging threats.
Vendors can better defend themselves against current threats to cybersecurity by breaking applications down into smaller components and allowing for the interchangeability of various cryptographic algorithms, including those that have not yet been developed. In addition, they can assist in better managing the unrestricted liability that is increasingly shifting to the software developer by ensuring that software and data remain protected from threats or vulnerabilities that have not yet been discovered.
