SDB:Secure coding checklist: C and C++ - openSUSE WikiThis article should serve as an checklist for developers to verify their code quickly for well-known security problems. Code that should run with higher privileges like system daemons or setuid applications need special care, because they are representing a high risk for system security. This kind of code should always be reviewed by the SUSE security team. Note: The purpose of this article is not to be complete and to describe special cases, but to be used easily and quickly verify your code. Both calls use the UNIX command shell to fulfill their work. Therefore, untrusted input will lead to a direct breach of system security shell commands can be executed with metachars , or command line options can be added or changed. It is better to avoid the usage of system 3 and replace it with a combination of fork 2 and exec 2 without exec'ing the shell of course.

CppCon 2018: “Secure Coding Best Practices: Your First Line Is The Last Line Of Defense (2 of 2)”
Author: Robert C. In C we need to keep the security of our code in mind all the time otherwise it can be compromised and form a route into the machine. This book aims to help you fix the problem before it starts. Security is a bigger problem for lower level languages in that it is generally the programmer's responsibility to make sure that code is secure. It is worth saying at this point that in this context "security" doesn't mean coding or encryption, but ways in which your code can contain vulnerabilities which can be exploited to take over the machine or to access data or resources that should be out of bounds. Most of the exploits are at the C level because its more direct approach to memory use. There are nine chapters in total and what they deal with is fairly obvious from their titles.
There is no reason to believe, however, that any "hierarchical oversight" would be welcome or useful in these arenas, so these safety and security problems present some very special challenges. This new library became the "bounds-checked library" . At that Oxford meeting, Plum Hall commented to Lovell that there was a need for automated assistance, so that the burden of remediation isn't borne totally by the application programmers themselves. Since that time, a second part has been added to the library Technical Report, which itemizes some alternative library functions from the POSIX and Linux standards . The intention of SSCC has been to make substantial improvements in reliability while working within these tight constraints.
Commonly exploited software vulnerabilities are usually caused by avoidable software defects. Having analyzed tens of thousands of vulnerability reports since , CERT has determined that a relatively small number of root causes account for most of the vulnerabilities. Seacord systematically identifies the program errors most likely to lead to security breaches, shows how they can be exploited, reviews the potential consequences, and presents secure alternatives. Thwart buffer overflows, stack-smashing, and return-oriented programming attacks that exploit insecure string manipulation logic. Avoid vulnerabilities and security flaws resulting from the incorrect use of dynamic memory management functions. Eliminate integer-related problems resulting from signed integer overflows, unsigned integer wrapping, and truncation errors.
