Our Team also consists of senior developers with years of experience in secure software development and specializing in Software Dependability and Cybersecurity.
We support the client in defining application security requirements, attack surface analysis, and threat modeling during design, before going into production. In order to proceed with the programming of secure software, it is essential to know the vulnerabilities that are introduced in the different phases of software development. If the client owns, develops and uses software, the Code Review phase is compulsory, as it corrects at the root flaws, bad programming habits and therefore future attack vectors. The revision modalities are decided according to the company development system and process: on release candidate or major version, periodic, on demand. Regardless of the development methodology adopted, the definition of security controls in applications begins with, or precedes, the design phase and continues throughout the life cycle of the application in response to changing organizational needs, in an environment that is constantly at risk and constantly evolving.
Security, as part of the software development process, is an ongoing process that involves people and practices and ensures the confidentiality, integrity, and availability of applications. Secure software is the result of security-aware software development processes in which security is built in, and thus software is developed with security in mind. Security is most effective when planned and managed at every stage of the software development life cycle (SDLC), especially in critical applications or those that process sensitive information. The solution to software development security is not just technology.
There are various security controls that can be incorporated into the application development process to ensure security and prevent unauthorized access. Security testing is essential to ensure that the system prevents unauthorized users from accessing its resources and data. Some application data is sent over the internet traveling through a variety of servers and network devices. This provides ample opportunities for unscrupulous hackers.
The National Institute of Standards and Technology (NIST2) has estimated that the cost of "code fixing" performed after the code is released for production can be 30 times the cost that would be incurred if such defects were identified and resolved in the design phase.
Key factors in this evolution are the advances made by attackers, the release of new technologies, and the use of increasingly complex systems. The targets of attacks are vulnerabilities, hidden within software applications, which provide an easy path of entry to compromise systems or launch new attacks and malware. Application weaknesses and software vulnerabilities continue to be the most common means by which cybercriminals carry out external attacks, and more seriously, exploitation of known vulnerabilities is still on the rise. Although these vulnerabilities can be fixed with appropriate measures, the most common vulnerabilities in Web applications continue to be the same as they have been in recent years: 60% have input validation errors, 70% have data encapsulation flaws or critical functionality within components, and over a third (35%) have issues caused by misuse of APIs, an acronym for Application Programming Interface. An API is, in the simplest terms, a software intermediary that allows two applications to talk to each other. An example: it's like being in a restaurant. The client sits at the table and orders from the menu, but needs an intermediary, in his case the waiter, to obtain the desired dish. The API is in this case the waiter!
