API Gateways and Microservices Security API gateways sit at the edge of a microservices stack. They act like a front door, deciding who can enter and how requests travel to backend services. When security is built into the gateway, teams can protect data, control traffic, and reduce risk across many services. This post shares practical ideas to strengthen API gateways and safeguard microservices without slowing delivery. The goal is simple: clear policies, verified identities, and trusted communication. ...

Secure coding practices for software developers Secure coding is a mindset as much as a set of rules. Developers who build today’s apps should expect bad inputs, weak passwords, and misconfigurations. The goal is to prevent common flaws from entering the product, through careful design, disciplined coding, and thorough testing. Security is a feature that travels with every sprint and every decision. Validate and sanitize at the boundary. Treat all inputs as untrusted. Use strict type checks, length limits, and allowlists of accepted values. Prefer built-in validation utilities and libraries, and avoid ad hoc string checks. This helps APIs, forms, file uploads, and data imports stay safe. Document your input rules so teammates apply the same standard. ...

Secure Coding Practices for Web Applications Secure coding is about building safety into software from the start. Web apps face many threats, from risky inputs to broken sessions. By following practical habits, developers can reduce risk without slowing down work. Input validation and output encoding Validate all input on the server side, not only in the browser. Use allowlists for formats and length limits. Sanitize and normalize data before use. Escape or encode output when rendering to prevent cross-site scripting. Keep messages simple for users and logs. ...

Secure Coding Practices for Web Applications Web applications face many threats every day. Secure coding means building software that resists attacks by design, not by luck. This guide shares practical practices you can apply in teams of any size. Input validation Validate all input on the server. Use allowlists for expected formats and reject anything else. Check type, length, range, and encoding. Use parameterized queries to prevent injection, and encode data when rendering it in HTML or JSON. Sanitize outputs only after validation, and avoid trusting data from clients. ...

Information Security Essentials for Developers Security is not a separate task for specialists. It is a daily practice for developers. By designing with security in mind, you reduce risk, catch mistakes early, and make maintenance easier for your team. Start with small, repeatable steps and build a safer product over time. Build securely from day one Think about threats when you plan features. Use a simple threat model to spot risky areas like login, data storage, and external calls. Choose designs that are easy to test and verify. In your CI pipeline, add security checks so a vulnerability cannot slip through. ...

Web Security Essentials: Preventing Common Attacks Web applications face many threats. Attackers look to steal data, disrupt services, or impersonate users. By understanding common tricks, you can design safer features from the start. Good security is a team effort, built into planning, development, and testing. Understanding common attacks SQL injection targets input that is used in database queries. Cross-site scripting (XSS) tricks the browser into running unsafe code. Cross-site request forgery (CSRF) uses a trusted user’s session to act on a site. Broken authentication and session management can let attackers pretend to be users. Insecure direct object references reveal data through predictable routes. Misconfigurations and weak defaults expose servers and data. Practical defenses you can apply Use parameterized queries and safe ORM methods to prevent SQL injection. Validate input and encode output, applying context-aware escaping for HTML, JavaScript, and URLs. Implement a strong Content Security Policy to limit where scripts come from. Prefer HttpOnly and Secure cookies; set SameSite to protect cookies from cross-site requests. Add anti-CSRF tokens to state-changing requests and verify them on the server. Enforce strong password policies and store hashes with modern algorithms like bcrypt or Argon2. Enable rate limiting and account lockout to slow brute-force attempts. Keep software, libraries, and plugins up to date; perform regular dependency checks. Use secure defaults and perform vulnerability testing as part of a secure development lifecycle. Safe development habits Include security reviews in code reviews and design discussions. Model threats during planning to spot risky features early. Automate security tests, including checks for input handling and session behavior. Avoid leaking debug information in production and log sensitive events safely. A quick scenario Imagine a login form. Use a real authentication flow, require strong passwords, rate-limit attempts, and store passwords with a strong hash. Validate inputs, protect cookies, and monitor for unusual activity. These steps make it much harder for attackers to succeed. ...

API gateways and service meshes in modern apps In modern applications, you often see both API gateways and service meshes working side by side. An API gateway sits at the edge, facing the internet, and handles north-south traffic. A service mesh runs inside the cluster, guiding east-west traffic between services with built-in security, retries, and observability. They solve different problems, but when used together they improve security, reliability, and visibility. ...

Application Security: Building Software That Resists Attacks Effective application security starts with the mindset that software must withstand hostile inputs, tricky data, and misused features. Security is not a single feature; it is a discipline that touches design, coding, testing, and operations. By planning for security from the start, teams reduce risk and build trust with users. Common attack patterns deserve attention. Injection flaws, such as SQL or NoSQL injections, remain a major risk. Cross-site scripting (XSS) can steal sessions or undermine trust. Broken access control lets users see or modify data they should not. Insecure deserialization and misconfigured cloud services also pose real threats. Regularly reviewing configurations, libraries, and data flows helps catch issues before they become incidents. ...

FinTech Security: Protecting Digital Wallets Digital wallets power everyday payments, transfers, and even crypto holdings. They bring speed and convenience, but they also attract risk from malware, phishing, and lost devices. This article summarizes practical steps you can take to protect funds and data. The goal is simple: reduce risk without slowing you down in daily work or personal life. Why wallets are targets Wallet apps sit at the edge of your finances. Attackers seek weak links like unsecured devices, shared networks, or overlooked updates. By understanding common threats, you can build a safer routine and keep control of your money. ...

Securing Web Applications with Modern Frameworks Security is a shared responsibility between the framework you choose and the way you build features. Modern frameworks provide strong protections out of the box, but you still need to configure them correctly and test regularly. A thoughtful setup reduces risk early and makes security part of your daily workflow. When you pick a framework, look for built-in defenses that minimize risk without heavy customization. Features like CSRF protection, secure defaults for cookies, and safe session handling help you build safer applications without writing extra code. ...
