It is deemed common among companies offering custom software development to ignore the security issues in the beginning phases of the SDLC or Software Development Lifecycle. In this approach, each succeeding phase inherits the vulnerabilities of the last one, and the final outcome cumulates multiple security breaches. In this way, your company will have to pay to halt these breaches and improve the software security in the future. Our dedicated software development team suggests you to integrate the security aspect into each phase of SDLC, right from the requirement analysis to the maintenance, no matter the project methodology, waterfall or agile.
Requirement analysis stage
- Employ a mixture of use and misuse cases.
The security consultants must foresee the potential threats to the software and express them in the misuse cases. Also, these cases should be covered simultaneously by the mitigation actions.
- Conduct security risk assessment and create a risk profile
When ascertaining the security risks, pay heed to the security guidelines from the relevant authoritative sources like SOX and HIPAA. You will find more requirements relevant to your business domain to be addressed.
- Least privilege: software architecture is allowed minimal user privileges for normal functioning.
- Privilege separation: particular actions in software are allowed to limited users with high privileges.
- Complete mediation: every user should be checked for authority for software access; lessens the chances of privilege escalation for a user within limited rights.
- Multiple security layers: this principle eliminates the threat of a single point security failure that compromises the entire software.
- Secure failure: if your software doesn’t operate, it should fail to secure a state.
- User friendly security: custom software design must incorporate security aspects so as the UX is not hindered. If the security mechanisms are obtrusive, users will turn them off.
The best secure development defends the software against the high risk vulnerabilities encompassing the OWASP top 10. In turn, these vulnerabilities need not be fixed later in the software cycle which reduces the customer overhead and remediation expenses. OWASP offers a comprehensive checklist for secure coding practices. Use it if you are looking for secure software development instead of descriptions of exploits.
This stage focuses on finding errors that hinder the application functionality. You can go for application penetrating testing. This operation must be performed in every build. To drive down the cost in this case, go for automated penetration tests that will scan every build to filter out the most critical vulnerabilities.
