Security Requirements Must Match a Security Definition

Authentication is described using the securityDefinitions and security keywords. You use securityDefinitions to define all authentication types supported by the API, and then use security to apply specific authentication types to the entire API or to individual operations. Well, you get the idea: if you don`t know, you can`t back it up! Not knowing this leads to surprising security breaches (think Target and its HVAC systems!). This means taking stock of what needs to be secured, and we need to know what commercial, regulatory and legal mandates and constraints are imposed on our organization, our product, or both. Web applications are created by application developers who distribute, sell, or transfer the application to an application provider for installation in a runtime environment. Application developers communicate declaratively by using the deployment descriptor mechanism or programmatically by annotating how to set the security of the deployed application. When this information is passed to the provider, the deployer uses it to set method permissions for security roles, establish user authentication, and determine whether to use HTTPS for transport. If you do not define the security requirements, the deployer must determine the security requirements independently. Then there`s my favorite excuse: „We`re an agile organization. With Agile, you don`t meet requirements and don`t write documentation.

When I hear that, I don`t know whether to laugh, cry, scream or bang my head against the wall. Obviously, these organizations don`t understand agility or security. Trust me: there are many organizations that follow exactly this practice. Most organizations experience exactly three security implementation issues: Security requirements are categorized into different compartments based on a higher-order common security feature. For example, ASVS includes categories such as authentication, access control, error management and logging, and web services. Each category contains a set of requirements that represent best practices for that category, created as verifiable statements. Implementing information security requirements allows your organization to be better prepared for the security threats you and your customers face, allowing you to protect against advanced security threats that put your business at risk. By familiarizing yourself with the commitments we`ve outlined in this blog, you`ll take your first steps toward implementing the information security requirements that work for you. The greatest obligation of companies in terms of information security is the ability to ensure the continuity of business services in the event that business operations are disrupted as usual by an event (such as the COVID-19 pandemic). All information security requirements must take business continuity into account.

By the way, these are not even very good design statements, as they leave too many questions open. For example, two of the three instructions require something to be „inspected” or „filtered” – inspected or filtered for what? They are simply incomplete and ambiguous, leaving too much unspecified – they are just begging to create security holes. Before you can authenticate a user, a database with user names, passwords, and roles must be configured on your web or application server. For more information about configuring the user database, see Managing Users and Groups on the Application Server and the Sun Java System Application Server 9.1 Administration Guide. A key mistake that too many organizations make is to use GRC mandates and constraints as actual security requirements. GRC mandates and constraints are almost always statements about what constitutes compliance, not the requirements that must be met to become compliant. That is, they do not specify what must happen to become compliant, but only the desired outcome. GRC documents should be among the sources to determine your security requirements, but not the only ones.

Once you`ve met all the security requirements and everyone else has agreed to them, you can now create your security design. Just make sure that all requirements are covered by your design and that there is a requirement that justifies each design statement. Here, traceability ensures that no one drops the ball along the way. Although the requirements engineering process is basic, this is not the purpose of this article. Instead, I`ll focus on what is and isn`t a requirement, and why it`s important to have strong security requirements. When I go to an organization for consulting work, one of the first questions I ask is, „What are your security requirements?” Usually, the answer is, „Formal requirements? We do not have one. Maybe this can help you create your API definitions. While there is an inventory of what needs to be secured, there should be a separate effort to determine the mandates and constraints placed on your security. For an organization, this effort should answer questions such as: If this is a product for which security requirements need to be defined: Now, I admit that the arguments about legacy systems and products are legitimate. Who knew twenty-five years ago that Grandma`s pacemaker could be hacked? Yes, a few of us cybersecurity veterans had an idea.

But until these vulnerabilities became publicly demonstrable, our concerns were not seriously addressed.
