Security requirements are classified 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. The final chapter of this OWASP standard addresses several configuration requirements, including: The requirements were developed with the following objectives in mind: The next chapter of ASVS 4.0 discusses the following file and resource requirements: Align security requirements with other types of requirements The Malicious Code chapter is designed to ensure that the following general requirements are met: This checklist covers authentication requirements, which include credential validation, credential secure storage, and validation of identity management paths and APIs. It covers password security requirements, general authenticator requirements, authenticator lifecycle requirements, credential storage requirements, credential retrieval requirements, secret search verification requirements, out-of-band verification requirements, single verification requirements for one or more factors, Software and Device Cryptographic Validation Requirements, and Service Authentication Requirements. ● Error management and logging: This Error Management and Logging section contains security guidelines for reviewing log content, log processing requests, and log protection requests. This checklist describes the requirements for managing logout and session timeout. It also includes session management based on cookies and tokens, as well as defenses against session management exploits. Define, structure, and include prioritization in the artifacts of the security requirements capture process? Apps are the main target for hackers for data theft and manipulation. A low level of security can cause irreparable damage to businesses and consumers. The use of appropriate security measures is of paramount importance, as a large number of applications are regularly exposed to cyberattacks. If we look at the statistics, about 43% of data breach attempts targeted web applications.
ASVS is one of OWASP`s key projects designed to improve application security. This article walks you through OWASP ASVS and its importance to security teams. Let`s review a concrete example: a small library of nodes for URL parsing. You can immediately remove any domains that do not apply to this library. In this case, you can delete V2, V3, V4, V6, V8, V9, V11, V12, V13, and V14, reducing the initial number of requests from more than 200 requests to just 89. Now, if you decide to start with risk level 1, these 89 requirements can be reduced to 30, which is a more bearable amount. Let`s see what kind of requests we find in the selected areas, as follows: ASVS stands for Application Security Verification Standard. The OWASP ASVS project contains a list of security requirements for testers, developers, security experts and consumers. ASVS establishes a framework of security requirements and controls that serve as the basis for testing technical security controls for Web applications. Configure a security requirements framework to help projects determine an appropriate and comprehensive set of requirements for their project. This framework takes into account the different types of requirements and the source of the requirements.
It should be adapted to organizational habits and culture, providing effective methodology and guidance for the collection and formation of requirements. This part of the standard recommends that the application`s APIs meet the following requirements: The following are the chapters in the ASVS document that provide guidance for meeting specific security requirements: This section contains all the business logic security requirements that protect the application from external threats. The new version includes a security checklist that supports compliance with OWASP Top 10 2017 and OWASP Proactive Controls 2018. The latest release is also PCI DSS 3.2.1 compliant because it includes chapters on buffer overflow, insecure memory operations, and compilation flags related to insecure memory. While ASVS previously focused on server-side controls, it now includes all APIs and applications. The new version no longer includes outdated or less relevant security controls. This chapter emphasizes the importance of using encryption and transport-layer security at all times. Application developers need to use advanced algorithms instead of relying on weak and outdated algorithms. Developers should make it a point to replace the weakest ciphers and algorithms from time to time to ensure optimal performance and security.
● New password requirements have been added, including password replacement and complexity requirements. Authentication tokens and password managers have been promoted. The ASVS Security Audit Checklist includes the following sections, which cover the verification requirements at all three ASVS levels. Let`s briefly dwell on each of them: ● It uses an efficient random number generator that serves the cryptographic requirements of the application. The framework also provides clear guidance on the quality of requirements and formalises how they are to be described. For user stories, for example, concrete instructions can explain what should be described in the definition of fact, definition of fact, description of the story, and acceptance criteria. The sole purpose of the ASVS was to show you what a modern security app looks like and eliminate some of the ambiguities of the things you need to do to secure it. At the same time, examine the feature from an attacker`s perspective to understand how it could be abused. This allows you to identify additional protection requirements for each software project. This is the highest level of security that can be built into an application. ASVS level 3 is generally preferred by applications that seek a high level of security, such as medical, military, and other mission-critical applications.
To meet Level 3 standards, applications must build layers of security from the ground up and document and audit their efforts. ASVS Level 1 is designed for core applications where privacy is not a priority and are less vulnerable to cyberattacks. However, this basic level of security must be met by each application. Security controls entered in this level protect the application from known vulnerabilities and all measures are testable without requiring access to source code or configurations. ● The various application APIs, such as cloud and serverless APIs, have all the essential security controls. The framework helps project teams increase the efficiency and effectiveness of requirements engineering. It can provide a categorization of common requirements and a set of reusable requirements. Keep in mind that even if thoughtless copying is ineffective, having potentially relevant requirements is often productive. ● Business logic is designed to fix security vulnerabilities such as rejection, identity theft, data theft, tampering, and other attacks.
Use a structured notation of security requirements in all applications and an appropriate formalism that integrates well with how you specify other (functional) requirements for the project. This can mean, for example, developing analysis documents, writing user stories, etc. The fourth chapter of the document establishes policies to ensure that your application meets the following access control requirements: Successfully exploiting security requirements involves four steps. The process involves discovering/selecting, documenting, implementing, and then confirming the correct implementation of new security features and capabilities within an application. Often, penetration testing is a better option when a new feature has been implemented and that feature needs to be explicitly tested. Or maybe the company only cares about a specific component of the application (like the database), and a thorough standardized security assessment is overkill. Level 2 policies apply to applications that perform business-to-business transactions. Following these guidelines helps application developers protect their applications from illegitimate access, injection failures, validation failures, and authentication failures.
ASVS Level 2 ensures that the measures implemented are consistent with the vulnerabilities and threats that pose a risk to the targeted application. ASVS level 2 is recommended by security experts to protect most applications. Testing at this level requires access to source code, documentation, configuration, and people involved in development.
