This app is designed to safely test that your antivirus product detects viruses and other harmful applications. It is based on the security industry standard test file recommended by European Institute for Computer Anti-Virus Research (EICAR) for testing antivirus software. The app is completely harmless.
When you download this app, your virus protection software should detect it as infected and recommend you to uninstall it. The app also works with any PC security software, but please note that your PC antivirus may automatically remove or quarantine it.
Top 10 Secure Coding Practices
Validate input. Validate input from all untrusted data sources. Proper input validation can eliminate the vast majority of software vulnerabilities. Be suspicious of most external data sources, including command line arguments, network interfaces, environmental variables, and user controlled files [Seacord 05].
Heed compiler warnings. Compile code using the highest warning level available for your compiler and eliminate warnings by modifying the code [C MSC00-A, C++ MSC00-A]. Use static and dynamic analysis tools to detect and eliminate additional security flaws.
Architect and design for security policies. Create a software architecture and design your software to implement and enforce security policies. For example, if your system requires different privileges at different times, consider dividing the system into distinct intercommunicating subsystems, each with an appropriate privilege set.
Keep it simple. Keep the design as simple and small as possible [Saltzer 74, Saltzer 75]. Complex designs increase the likelihood that errors will be made in their implementation, configuration, and use. Additionally, the effort required to achieve an appropriate level of assurance increases dramatically as security mechanisms become more complex.
Default deny. Base access decisions on permission rather than exclusion. This means that, by default, access is denied and the protection scheme identifies conditions under which access is permitted [Saltzer 74, Saltzer 75].
Adhere to the principle of least privilege. Every process should execute with the the least set of privileges necessary to complete the job. Any elevated permission should be held for a minimum time. This approach reduces the opportunities an attacker has to execute arbitrary code with elevated privileges [Saltzer 74, Saltzer 75].
Sanitize data sent to other systems. Sanitize all data passed to complex subsystems [C STR02-A] such as command shells, relational databases, and commercial off-the-shelf (COTS) components. Attackers may be able to invoke unused functionality in these components through the use of SQL, command, or other injection attacks. This is not necessarily an input validation problem because the complex subsystem being invoked does not understand the context in which the call is made. Because the calling process understands the context, it is responsible for sanitizing the data before invoking the subsystem.
Practice defense in depth. Manage risk with multiple defensive strategies, so that if one layer of defense turns out to be inadequate, another layer of defense can prevent a security flaw from becoming an exploitable vulnerability and/or limit the consequences of a successful exploit. For example, combining secure programming techniques with secure runtime environments should reduce the likelihood that vulnerabilities remaining in the code at deployment time can be exploited in the operational environment [Seacord 05].
Use effective quality assurance techniques. Good quality assurance techniques can be effective in identifying and eliminating vulnerabilities. Fuzz testing, penetration testing, and source code audits should all be incorporated as part of an effective quality assurance program. Independent security reviews can lead to more secure systems. External reviewers bring an independent perspective; for example, in identifying and correcting invalid assumptions [Seacord 05].
Adopt a secure coding standard. Develop and/or apply a secure coding standard for your target development language and platform.
Bonus Secure Coding Practices
Define security requirements. Identify and document security requirements early in the development life cycle and make sure that subsequent development artifacts are evaluated for compliance with those requirements. When security requirements are not defined, the security of the resulting system cannot be effectively evaluated.
Model threats. Use threat modeling to anticipate the threats to which the software will be subjected. Threat modeling involves identifying key assets, decomposing the application, identifying and categorizing the threats to each asset or component, rating the threats based on a risk ranking, and then developing threat mitigation strategies that are implemented in designs, code, and test cases [Swiderski 04].

Tips: Chattr : une commande pour empêcher la suppression des fichiers et répertoires | crowd42crowd42
Under GNU/Linux if you use
sudo chattr +i file
sudo chattr -i file
you can protect (and respectively remove the protection) a file against deletion even by the root account!
The parameter “-R” allows to do the same for a directory:
sudo chattr +i -R directory
sudo chattr -i -R directory
This tool seems to be installed by default in all the GNU/Linux distributions.

A few days ago, I discussed with a supposedly IT expert and professional that gave me the “Apple & Mac OS products do not need any security softwares (anti-virus & all)” and “there is no such thing as a malware on Apple products” speech. Since the first danger is blissful ignorance, we decided to relay some links here and leave you the conclusion. By this post, we do not make any judgment on any product. We are merely relaying existing public information.
Here is a few links regarding this allegation:
- Mac malware found in malformed Word documents – is China to blame?
- Does apple recommend running anti-virus software with snow leopard? ”
It is always wise to have protection. Even with Mac’s being a low target of viruses. Typically you can pick up a computer virus although, it might not affect your Mac you can pass it on to your Windows Friends/Co-workers. Rather you use Snow Leopard or any other version of Mac OS you should consider an antivirus software. However, I would not rush out in panic.
- Apple suggests Mac users install antivirus software: “Apple is recommending that Mac users install antivirus software.”
- As they did in June 2007, Apple again encourages Mac users to use multiple antivirus utilities
- Apple quietly recommends using antivirus software
- OS X Mountain Lion: Protect your Mac from malware
- OS X Mountain Lion: What is malware?
- How to avoid or remove Mac Defender malware : From support.apple.com “A recent phishing scam has targeted Mac users by redirecting them from legitimate websites to fake websites which tell them that their computer is infected with a virus. The user is then offered Mac Defender “anti-virus” software to solve the issue.”
