Broken Authentication Weaknesses in password management and session handling Unauthorized access, account takeover
Sensitive Data Exposure Failure to properly protect sensitive data, such as passwords and financial information Data theft, identity fraud

Secure Software Concepts

Creating secure software is very important today. It means following important rules and methods. These help make apps safe and strong against cyber threats.

The main idea is secure by design. This means thinking about security right from the start. It makes sure security is a big part of making the software, not just an add-on later. This way, apps can be safer from the start.

Security as code (SaC) changes how we think about security. It makes security a part of making software, not just something added later. This helps keep software safe and secure all the time.

The principle of least privilege is also key. It means giving users and apps only what they need to do their jobs. This makes it harder for hackers to cause big problems if they get in.

Secure Software Concept Description
Secure by Design Incorporating security considerations from the start of the software development lifecycle to reduce the attack surface.
Security as Code (SaC) Automating security practices and integrating them seamlessly into the software development lifecycle.
Principle of Least Privilege Restricting user and application access to only the necessary resources, minimizing the potential damage of a breach.

These ideas, along with others like separation of duties and complete mediation, help make software safe and reliable. By using these, developers can make apps that are strong against cyber threats. This keeps data safe and secure.

Secure Software Development Lifecycle

The secure software development lifecycle (SSDLC) makes security a key part of every step in making software. It makes sure security is a top priority from the start. This way, teams can find and fix risks early on.

Planning and Requirements Analysis

At the start, security is vital for setting goals and what the system needs. It’s about spotting risks, seeing how they could hurt us, and adding security steps early on. Security experts and developers work together to make sure security is part of the software’s core.

Design and Architecture

Designing software securely is very important. Developers must think about security when planning the software’s structure and parts. They use secure coding and security tools, and think about how attackers might try to get in.

Threat modeling helps spot and study threats. This makes the software stronger against cyberattacks.

Using secure SDLC ideas at every step helps teams tackle security issues early. This makes the software safer and better at fighting cyber threats. This way of thinking is key to keeping the final product safe and sound.
