Secure and Reliable PHP Applications php|architect's Guide to PHP Security and removes portal7.info extension, and the filename of the PDF document is. There are many ways to start a guide or book on PHP Security. Unfortunately, I haven't read any of them, so I have to make this up as I go along. PHP & Security. ▫ PHP keeps on growing as a language, making headway into enterprise and corporate markets. ▫ Consequently PHP applications often end.
Using the OWASP Mobile App Security Verification Standard, Testing Guide and Checklist The documents produced in this project cover many aspects of mobile application security, from the high-level requirements to the nitty-gritty implementation details and test cases. They can be used to plan and verify security controls during any phase of mobile app development, as well as during pre-release code review and penetration testing. The Mobile Application Security Verification Standard MASVS contains generic security requirements along with mappings to verification levels that can be chosen depending on the overall need for security. It is also useful as a standalone learning resource and reference guide for mobile application security testers. It also conveniently links to the MSTG test case for each requirement, making mobile penetration testing a breeze. It is important to note that the security standard, testing guide and checklists are closely related: They all map to the same basic set of requirements.
The attacker can use this file to pull sensitive information about your system. For more information about file inclusion attacks, read Wikipedia's File inclusion vulnerability article.
This would allow an attacker to discover basic information about your web server's accounts. This feature limits an attacker's access to a single directory via local includes and makes local file inclusion attacks more difficult. Remote File Inclusion attacks RFI attacks occur when an attacker pulls files from a remote location on your server. An insecure PHP configuration allows attackers to execute the malicious data from their servers, even without read or write permissions on your server.
Ask your developers to standardize on one or two of these functions for a task so that you can disable the rest. You can only disable internal PHP functions.
Prevent information disclosure Error messages that disclose important system information can help attackers plan an attack strategy.
For example, the MASVS requirements may be used in the planning and architecture design stages, while the checklist and testing guide may serve as a baseline for manual security testing or as a template for automated security tests. Mobile App Security Testing The checklist works great as a reference during mobile app security assessments.
You can walk through the requirements one-by-one - for more information on each requirement, simply click on the link in the "Testing procedures" column. Or, fill out the checklist at the end of an assessment to ensure completeness. The MASVS levels can be used along with threat modeling to determine the appropriate set of security controls for a particular mobile app. MASVS V1 also lists requirements pertaining to the architecture and design of the mobile apps, as well as general processes and activities that should be part of the development process.
Its main chapters contain general how-tos and tutorials that cover a variety of topics from mobile OS internals to advanced reverse engineering techniques.
With the Mobile Security Testing Guide sponsorship packages, we offer companies opportunities to create brand awareness and maximize visibility in the mobile security space. A limited amount of sponsorship packages will be made available shortly through our crowdfunding campaign. We will contact you as soon as the packages become available. Why Sponsors?
Also, professional editors, graphic designers and layouters don't work for free. Thus, some funds are needed to make the tech book a reality. Want to know more? Head over to the Github release page! Head over to the Github release page May 7th, New release of the MSTG After many changes, we decided it was time to create a new release in order to improve the book version!
In this update we have a lot to share! In the meantime, we have worked on an actual print of the book! While an early version is available through Hulu no link supplied, google and download at your own risk , we are working on making a better version of that book. In the mean time we have filed for a project promotion to Flagship!
We are proud to be part of such a great project! Next, we are preparing to join the Open Security Summit again! Already three people will be on site, and at least one remoting, but we would love to work with more people at the project again! January 15th, Release of improved checklist We released a new version of the checklist! This version has adaptable references so that it can be used with newer versions of the MSTG as well. If for some reason this shouldn't work, then the "Not with me my friend" text apears or a redirection depending what is used In my eyes this looks o.
If your PHP pages include or require files that live within the web server document root, for example library files in the same directory as the PHP pages, you must account for the possibility that attackers may call those library files directly. Any program level code in the library files ie code not part of function definitions will be directly executable by the caller outside of the scope of the intended calling sequence.
An attacker may be able to leverage this ability to cause unintended effects.
The most robust way to guard against this possibility is to prevent your webserver from calling the library scripts directly, either by moving them out of the document root, or by putting them in a folder configured to refuse web server access.
With Apache for example, create a. Order Allow,Deny Deny from any.
In Reply to djjokla and others Consider placing all incude files as mentioned before in a seperate folder containing a. I'd recommend a over a considering a proves there is something worth hacking into.
Password hashing should be linked here: Since many users can not modify apache configurations or use htaccess files, the best way to avoid unwanted access to include files would be a line at the beginning of the include-file: Don't use it as one.
Please read the man pages of chroot to understand what its really used for. Not the best, but fairly unobtrusive, provides several levels of checkpoints, and has only the detriment of being, well, kinda slow.
