Security testing service – is the assessment of the software being vulnerable to a variety of attacks.

Computer systems are often the target of illegal penetration. Security testing as a service verifies a factual reaction of protective mechanisms that are built into the system. In the course of security testing, tester plays the role of a cracker. Security testing companies allow their testers to do everything they want:

• to attempt to find out the password using external tools;
• to attack the system using special utilities that analyze the security;
• to suppress & shock the system;
• to perform a targeted entrance of errors in order to penetrate to the system during its recovery;
• to view unclassified data in hopes of finding the key to enter the system.

With unlimited time and resources, a good security testing breaks into any system.

Three Main Principles of the Software Security

The overall security strategy is based on three main principles:

• Privacy.
• Integrity.
• Accessibility.

Privacy – means hiding a certain resources or information. Under privacy, one can understand the access restriction to a particular resource of a certain user category.

Integrity – there are two main criteria for understanding the given principle:

• Trust.
• Damage & recovery.

Accessibility – is a requirement, which represents that resources should be available to an authorized user, internal object or device. Generally, the more critical resource is, the higher level of accessibility should be.
