Secure Code

[Nicholas Mahendra]

Securecoding, the principle of designing code that adheres to code security best practices, safeguards and protects published code from known, unknown and unexpected vulnerabilities such as security exploits, the loss of cloud secrets, embedded credentials, shared keys,confidential business data and personally identifiable information (PII).

It reflects a wider understanding among developers, security teams and DevOps that code security must be enforced as an integral part of CI/CD, supporting continuous changes both in code and in infrastructure, providing visibility into all seen and hidden components of a given environment.

Secure coding demonstrates a changing shift in responsibility by literally naming the developer as responsible for code security rather than a security team. This also paves the way for the Shift-left security concept that is already being widely adopted as part of the Software Development Life Cycle (SDLC) best practices.

Creating software, applications or writing infrastructure as code requires cloud secrets to access and control cloud resources, and sensitive parameters saved to enable automation. There are countless scenarios that could introduce vulnerabilities into your code, and below we explore the most critical and frequent issues encountered:

Each application has an embedded configuration dataset that details the security parameters the application uses against associated apps. This might include database login credentials, database parameters, middleware configuration variables, or access details for front/back end web application services. The parameters and secrets should be encrypted and never written in plain text, but some applications only use file system permissions to protect unauthorized users from reading the configuration. If features like .gitignore is not used in the code committal, the file will be saved in plaintext.

CloudGuard Spectral by Check Point is a professional automation tool that validates and enforces secure coding best practices. It prevents developers and DevOps from making costly mistakes by using automated routines to discover, identify and predict the vulnerabilities inyour code, providing powerful shift-left provenance from code to cloud.

Supercharge your IaC and CI/CD with end to end secret and misconfiguration scanning across your SDLC. Eliminate public blindspots by enforcing security policies uniquely matched to your business. Schedule a demo of CloudGuard Spectral to uncover security concerns you most likely not aware of, and learn how to promote a developer first security narrative throughout the business.

Most applications make use of large amounts of third-party components. These components provide everything from logging, templating, database access, and more. This makes developing software much easier and saves a lot of time. But they're also made by people, which means some will inevitably contain vulnerabilities. Read the guideline to find out more.

SQL injection (SQLi) injects code into SQL statements to attack and gather important information from an application. It is a web security vulnerability. It is the most common technique of hacking that manipulates the database and extracts crucial information from it.

I'm on the Arlo app and need to enter the 16 digit security code for the free 3 month subscription. I bought Arlo Pro 4XL package from Costco and there is no code on the receipt or email Arlo sent me when I registered. Arlo's Chatbot is useless for this type of question and there is NO live chat or live person to talk to. Wondering if I made a mistake purchasing this product. Please help, where do I get the code or otherwise activate the free trial?

Automated code review is a process in which a tool automatically reviews the source code of an application, using a predefined set of rules to look for inferior code. Automated review can find issues in source code faster than identifying them manually.

In its first iterations, code review involved lengthy, time-consuming formal reviews. As development speeds increased, this longer review evolved into a more dynamic and lightweight process that keeps pace with agile and modern development methodologies.

Today, there are review tools available that easily integrate into SCM/IDEs. Tools like static application security testing (SAST) provide inputs in addition to manual reviews, helping developers find and fix vulnerabilities. These tools are compatible with numerous development environments like GitHub and GitLab, or IDEs like Eclipse and IntelliJ, so developers can work in their preferred environment.

Automated review enables large codebases to be quickly and efficiently analyzed. Developers perform this review using either open source or commercial tools while they are coding, to help find vulnerabilities in real time. The most advanced development teams also include SAST tools, which can provide additional inputs, help find vulnerabilities, and enable developers to fix them before the code is checked in. The most successful development processes also involve developers performing their own self-reviews as they code.

Manual review involves a thorough review of the entire codebase by a senior or more experienced developer. This process can be extremely tedious and time-consuming, but it identifies flaws, such as business logic problems, that automated tools may miss. Layering in QA tests can help as well, but there are still scenarios that manual testing can miss. The best practice is a combination of automated and manual review.

Synopsys is a recognized leader in the application security industry. With its state-of-the-art Coverity SAST solution, Synopsys can help developers improve their productivity during the code review process.

Coverity is easily integrated with your SCM of choice. For example, Coverity easily integrates into GitLab pull requests, providing additional sources of feedback and a method to easily find policy violations before code is checked in. By adding feedback from SAST into your SDLC, you provide useful guidelines to fix security defects.

Secure coding is the practice of developing computer software in such a way that guards against the accidental introduction of security vulnerabilities. Defects, bugs and logic flaws are consistently the primary cause of commonly exploited software vulnerabilities.[1] Through the analysis of thousands of reported vulnerabilities, security professionals have discovered that most vulnerabilities stem from a relatively small number of common software programming errors. By identifying the insecure coding practices that lead to these errors and educating developers on secure alternatives, organizations can take proactive steps to help significantly reduce or eliminate vulnerabilities in software before deployment.[2]

Buffer overflows, a common software security vulnerability, happen when a process tries to store data beyond a fixed-length buffer. For example, if there are 8 slots to store items in, there will be a problem if there is an attempt to store 9 items. In computer memory the overflowed data may overwrite data in the next location which can result in a security vulnerability (stack smashing) or program termination (segmentation fault).[1]

A Format String Attack is when a malicious user supplies specific inputs that will eventually be entered as an argument to a function that performs formatting, such as printf(). The attack involves the adversary reading from or writing to the stack.

The C printf function writes output to stdout. If the parameter of the printf function is not properly formatted, several security bugs can be introduced. Below is a program that is vulnerable to a format string attack.

Integer overflow occurs when an arithmetic operation results in an integer too large to be represented within the available space. A program which does not properly check for integer overflow introduces potential software bugs and exploits.

The problem with the code is it does not check for integer overflow on the addition operation. If the sum of x and y is greater than the maximum possible value of an unsigned int, the addition operation will overflow and perhaps result in a value less than or equal to MAX, even though the sum of x and y is greater than MAX.

For example, consider a script that fetches an article by taking a filename, which is then read by the script and parsed. Such a script might use the following hypothetical URL to retrieve an article about dog food:

Depending on the script, this may expose the /etc/passwd file, which on Unix-like systems contains (among others) user IDs, their login names, home directory paths and shells. (See SQL injection for a similar attack.)

Secure coding, also referred to as secure programming, involves writing code in a high-level language that follows strict principles, with the goal of preventing potential vulnerabilities (which could expose data or cause harm within a targeted system).

Secure coding is more than just writing, compiling, and releasing code into applications. To fully embrace secure programming, you also need to create a secure development environment built on a reliable and secure IT infrastructure using secure hardware, software, and services and providers.

And the danger is real: Media reports in recent years have highlighted just how insecure much of the software we use is. Even major organizations with the resources and knowledge at their disposal have experienced serious data breaches. For companies that provide software to consumers or enterprises, customer trust is of course extremely valuable, and losing that trust could impact their bottom line. Ensuring secure coding practices therefore must be a top priority for these organizations.
