How To Keep Calm And Become A Security Engineer

Mohamed has many contributions for OWASP, he is the author for the “OWASP application threat modeling cheat sheet” and a board member of OWASP Middle-East. Consultant at ZINAD IT, holding GSSP-JAVA, GSNA, GSEC, ISO27001 LA/LI & Lead SCADA Security Professional certificates. Threat modelling is an engineering exercise that aims to identify threats, vulnerabilities and attack vectors that represent a risk to something of value. Based on this understanding of threats, we can design, implement and validate security controls to mitigate threats. Static Analysis Security Testing tools scan software for vulnerabilities without executing the target software.

Typically, static analysis will scan the source code for security flaws such as the use of unsafe functions, hard-coded secrets and configuration issues. SAST tools often come in the form of IDE plugins and CLIs that can be integrated into CI/CD pipelines. Infrastructure as Code allows applications to be deployed reliably to a consistent environment.

For example, if a method calls the constructor to read an underlying configuration file and that file is not present, a containing the file path is thrown. Propagating this exception back to the method caller exposes the layout of the file system. It is also important to understand the security model and best practices for third-party software. Identify secure configuration options, any security-related tasks performed by the code (e.g. cryptographic functions or serialization), and any security considerations for APIs being used.

OWASP Proactive Controls Lessons

For instance, checks the guard before serializing the target object. With full permissions, this guard can be circumvented and the data from the object made available to the attacker. Security-sensitive serializable classes should ensure that object field types are final classes, or do special validation to ensure exact types when deserializing. Otherwise attacker code may populate the fields with malicious subclasses which behave in unexpected ways.

Enhancing Application Security By Practicing Secure Coding

Data can contain sensitive information which requires more protection, since it may fall under laws and regulations. It is important to classify data in your system to determine sensitivity. Proactive controls are security techniques that we can apply to our software development projects. In this case, OWASP lists the top 10 that we should consider for every software development project. Once you’ve identified your focus with threat modeling, it’s time to move on to the next step of creating a list of security requirements relevant to your application and organization.

They were trying to stop her from cheating on her diet because they are the “diet police.” Diet police? It does when you remember that she had defined abdominals which means she must be on a strict diet, right? The point is that this is a story that puts meaning to the placement of the image on the location. Logically it doesn’t make sense, but you’re going to remember it because that’s a memorable reason. I could tell you that software is one of the most significant attack vectors.

Developers should consider exposing read-only copies of collections relating to security authentication or internal state. Only immutable or unmodifiable values should be stored in public static fields. Many types are mutable and are easily overlooked, in particular arrays and collections. Mutable objects that are stored in a field whose type does not have any mutator methods can be cast back to the runtime type. This guideline does not apply to classes that are designed to wrap a target object. For instance, java.util.Arrays.asList operates directly on the supplied array without copying. The intrinsic lock and fields of the two objects will be different, but referenced objects will be the same.

When putting images on a dresser, you can see the images flying out of the drawers you can see the images smashing into it like a meteor flying out of the sky. For a lamp, you can knock it over, smash it, materialize from the light. Tall dressers you can knock over, leap on or leap off, come out of the shelves, bookshelves can have books knocked off. Closet doors can swing open and shut quickly, and you can smash through them. Pick your journey locations for immediate recall and clarity while traveling through them in your mind. Picking too many locations on a journey or clustering them together too tightly will be frustrating when using the journey later.

Dependency Management

For example, exceptions related to file access could disclose whether a file exists. An attacker may be able to gather useful information by providing various file names as input and analyzing the resulting exceptions. In rare cases it may not be practical to ensure that the input is reasonable. It may be necessary to carefully combine the resource checking with the logic of processing the data. In addition to attacks that cause excessive resource consumption, attacks that result in persistent DoS, such as wasting significant disk space, need be defended against. Documenting this information in comments for a tool such as Javadoc can also help to ensure that it is kept up to date.

  • I do acknowledge the need for standing up for justice and actively defending society against violence or injustice.
  • In this post, you’ll learn how using standard and trusted libraries with secure defaults will greatly help you implement secure authentication.
  • Separating parts of the application that require elevated privileges or that are more exposed to security threats can help to reduce the impact of security issues.
  • This includes making sure no sensitive data, such as passwords, access tokens, or any Personally Identifiable Information is leaked into error messages or logs.
  • This means that code outside the module can access those public classes and public interfaces, but cannot access the classes and interfaces in other packages of the module even if they are public.

The OWASP Top Ten Proactive Controls 2018 is a list of security techniques that should be included in every software development project. They are ordered by order of importance, with control number 1 being the most important.

Once authentication is taken care of, authorization should be applied to make sure that authenticated users have the permissions to perform any actions they need but nothing beyond those actions is allowed. In this post, you’ll learn more about the different types of access control and the main pitfalls to avoid. ● The business logic is designed to address security flaws like repudiation, spoofing, data theft, tampering, and other attacks. In order to achieve secure software, developers must be supported and helped by the organization they author code for.

OWASP Proactive Controls Lessons

As software developers author the code that makes up a web application, they need to embrace and practice a wide variety of secure coding techniques. All tiers of a web application, the user interface, the business logic, the controller, the database code and more – all need to be developed with security in mind.

Further, objects assigned to fields should never have referenced untrusted data due to the dangers of unsafe publication. In rare cases it may be safe to call a copy method on the instance itself. For instance, is mutable but final and provides a public clone method for acquiring copies of its instances. If a method returns a reference to an internal mutable object, then client code may modify the internal state of the instance.

In non-final classes Object.clone will make a new instance of the potentially unsafe or malicious subclass. Implementing Cloneable is an implementation detail, but appears in the public interface of the class. An attacker might be able to control ClassLoader instances that get passed as arguments, or that are set in Thread context. Thus, when calling methods on ClassLoaders not many assumptions can be made. Multiple invocations of ClassLoader.loadClass() are not guaranteed to return the same Class instance or definition, which could cause TOCTOU issues. The primary flaw is that the data belonging to Provider is stored in the Hashtable class, whereas the checks that guard the data are enforced in the Provider class.


Default deserialization and ObjectInputStream.defaultReadObject can assign arbitrary objects to non-transient fields and does not necessarily return. Use ObjectInputStream.readFields instead to insert copying before assignment to fields. If the security-sensitive class is non-final, this guideline not only blocks the direct instantiation of that class, it blocks unsafe or malicious subclassing as well.
