OWASP Top Ten Proactive Controls 2018 C7: Enforce Access Controls OWASP Foundation

If the database is compromised at the same time, the attacker will be able to access the user account easily. The attacker will be able to login to the user’s account using the username and password from the database, which is stored in plain text. If the access control check at any point in 1-5 fails, then the user will be denied access to the requested resource. Depending upon the programming language a developer uses to build an application, regular expression can easily be implemented in it. Another advantage of regular expressions is that there are many industry tested regular expressions for all popular input types. It is better to use industry tested regular expressions than writing one on your own (which in most cases will be flawed).

One of the main goals of this document is to provide concrete practical guidance that helps developers build secure software. These techniques should be applied proactively at the early stages of software development to ensure maximum effectiveness. Software and data integrity failures include issues that do not protect against integrity failures in software creation and runtime data exchange between entities.

Then the user input is added to it where it is needed, but treated as a particular data type string, integer, etc. as whole. In a database operation with a parameterized query in the backend, an attacker has no way to manipulate the SQL logic, leading to no SQL injection and database compromise. Applications contain numerous “secrets” that are needed for security operations.

• There are also third party suppliers of Identity and Access Management (IAM) that will provide this as a service,
  consider the cost / benefit of using these (often commercial) suppliers.
• It is important that security is built into applications from the beginning and not applied as an afterthought.
• On Android this will be the Android keystore and on iOS this will be the iOS keychain.
• In order to achieve secure software, developers must be supported and helped by the organization they author code for.
• A lack of input validation and sanitization can lead to injection exploits,
  and this risk has been a constant feature of the OWASP Top Ten since the first version was published in 2003.

These include certificates, SQL connection passwords, third party service account credentials, passwords, SSH keys, encryption keys and more. The unauthorized disclosure or modification of these secrets could lead to complete system compromise. Supported by industry-leading application and security intelligence, Snyk puts security expertise in any developer’s toolkit.

Developer Guide (draft)

The Top Ten calls for more threat modeling, secure design patterns, and reference architectures. Threat modeling analyzes a system representation to mitigate security and privacy issues early in the life cycle. Secure design owasp proactive controls patterns and reference architectures provide a positive, secure pattern that developers can use to build new features. To solve this problem, access control or authorization checks should always be centralized.

Ideally, your application should also respond to a possible identified attack, by for example invalidating the user’s session and locking the user’s account. The response mechanisms allows the software to react in realtime to possible identified attacks. The OWASP Top 10 Proactive Controls is similar to the OWASP Top 10 but is focused on defensive techniques and controls as opposed to risks.

Benefits of Security Logging

While the current OWASP Proactive Controls do not match up perfectly with the OWASP Top Ten for 2021, they do a fair job of advising on controls to add to your applications to mitigate the dangers the Top Ten describes. Logging is storing a protected audit trail that allows an operator to reconstruct the actions of any subject or object that performs an action or has an action performed against it. Monitoring is reviewing security events generated by a system to detect if an attack has occurred or is currently occurring. This patched code will invalidate the session when authentication is successful and creates a new session cookie value. This changes the post-login session cookie value, and Session Fixation vulnerability cannot be exploited. Authentication is the process by which it is verified that someone is who they claim to be, or we can say it is the process of identifying individuals.

If at any point in time you have to modify an access control check, then you will have to change it at multiple locations, which is not feasible for large applications. Implementing authorization is one of the key components of application development. It has to be ensured at all times that access certain parts of the application should be accessible to users with certain privileges only. The answer is with security controls such as authentication, identity proofing, session management, and so on. It lists security requirements such as authentication protocols, session management, and cryptographic security standards.
