Testing is not a new profession, instead today every software project needs to be tested. When it comes to making a career in testing, then you gather all the information that is required to become a professional tester. Here, in this blog, we will discuss the security testing interview questions answer rather than the software testing today.
Security testing is quite different from software testing, as in this phase the application or the software is tested for the security or vulnerabilities present in the application. The questions answers are discussed for both fresher and experienced and they are usually asked by the interviewers to test your knowledge.
Security testing process is used to identify or detect the flaws in the security mechanism of the information system. An information system basically protects data and maintains the functionality as per user expectation and requirement.
For any application security testing is one of the most important types of testing for any application. In this type of testing tester himself plays the role of attacker and plays around the application to find the bugs of the system. Security testing is considered one of the most important types of testing among all types of testing that are available today.
Security testing is one of the most important types of testing and its objective is to find bugs or vulnerabilities of the software or any desktop or web-based application. It is being done to protect the data from an unexpected attack or intruder.
Many applications contain confidential data that may require protection. It must be done periodically in order to identify the threats so that an immediate action can be taken if an attack is being done.
The weakness of any system due to which any bug or intruder can attack the system is known as its vulnerability. If testing is not performed rigorously of the system then chances of attack get increased. To avoid such attacks time to time patches and fixes are applied to prevent the system from any unpredicted vulnerability.
Intrusion detection system basically detects the possibility of an attack and many times deals with it as well. Basically, it collects the information from a number of sources, analyzes the information and finds out all possible ways to attack the system. It checks for the following:
Commonly hackers attack the system with this technique that is known as SQL injection to hack all critical data. They check and try to find any system loophole, in which they find a query that bypasses the security check and returns back critical data. This process is known as SQL injection; it can not only hack the data but sometimes even crash the system.
The SQL injections are quite critical so must be avoided. They can be avoided by the periodic attack. SQL database security must be defined correctly in that input boxes and special characters must be handled properly.
Following attributes are considered for security testing:
SSL or secured socket layer connection is a transient connection that is established to set-up peer-to-peer communication. In these connections, each connection has one SSL Session.
SSL session is defined as an association between client and server. Usually, handshake networking protocol is used in these connections. The parameters that are defined in these connections must be shared by multiple SSL connections.
Penetration testing is done to identify and detect the system vulnerabilities. In this testing manual and automatic techniques are used to detect system vulnerabilities. After identification of the vulnerability, testers try to find more vulnerability associated with this one by accessing the system deeply.
This testing helps in preventing the system from any possible attack. Testers perform this testing in two ways either white box testing and black box testing.
In case of white box testing, all information is available with the testers, while in case of black box testing testers test the system in the real-world environment without any information and find out the vulnerabilities.
Due to following reasons Penetration testing must be used by the testers:

Below-listed abbreviations are used in software security and they are given with their full-forms:
Below listed factors can cause vulnerability:
This standard is published in the UK that defines the practices that must be followed for software security. This standard has guidelines for all size organizations including small, medium and large size organizations.
Testing can be of following types:

As per Open Source Security Testing methodology manual following seven types of testing may exist:
SOAP is Simple Object Access Protocol that is an XML based protocol that is used to exchange information over HTTP. Web services send XML requests in SOAP format and then SOAP client sends a message to the server. The server then responds back with a SOAP message.
WSDL or Web Services Description Language is an XML formatted language that is used by UDDI. It describes the web services and the way in which they can be used and accessed.
