Application Security

Application Security is the process of developing, adding, and testing security features within applications to prevent security vulnerabilites against threats such as unauthorized access and modification.

Why application security is important ?

Application security is important because today applications are often available over various networks and connected to the cloud. Increasing vulnerabilities to security threats and breaches. There is increasing pressure and incentive to not only ensure security at the network level but also within applications themselves. One reason for this is because hacker are going after apps with their attacks more today than in past. Applications security testing can reveal weakness at the application level., helping to prevent these attacks.

Types of Application Security

Different types of application security features include authentication, authorization, encryption, logging, and application security testing. Developers can also code applications to reduce security vulnerabilities.

  • Authentication: When software developers build procedures into an application to ensure that only authorized users gain access to it. Authentication procedures ensure that a user is who they say they are. This can be accomplished by requiring the user to provide a user name and password when logging in to an application. Multi-factor authentication requires more than one form of authentication—the factors might include something you know (a password), something you have (a mobile device), and something you are (a thumb print or facial recognition).
  • Authorization: After a user has been authenticated, the user may be authorized to access and use the application. The system can validate that a user has permission to access the application by comparing the user’s identity with a list of authorized users. Authentication must happen before authorization so that the application matches only validated user credentials to the authorized user list.
  • Encryption: After a user has been authenticated and is using the application, other security measures can protect sensitive data from being seen or even used by a cybercriminal. In cloud-based applications, where traffic containing sensitive data travels between the end user and the cloud, that traffic can be encrypted to keep the data safe.
  • Logging: If there is a security breach in an application, logging can help identify who got access to the data and how. Application log files provide a time-stamped record of which aspects of the application were accessed and by whom.
  • Application security testing: A necessary process to ensure that all of these security controls work properly.

Mobile Application Security

Mobile devices also transmit and receive information across the internet, as opposed to a private network, making them vulnerable to attack. Enterprises can use virtual private networks to add a layer of mobile application security for employees who log in to applications remotely. IT departments may also decide to vet mobile apps and make sure they conform to company security policies before allowing employees to use them on mobile devices that connect to the corporate network. 

Web Application Security

Web application security applies to web applications – aps or services that users access through a browser interface over the internet. Because web applications live on remote servers, not locally on user machines, information must be transmitted to and from the user over the internet. Web application security is of special concern to businesses that host web applications or provide web services. These businesses often choose to protect their network from intrusion with a web services. A web application firewall works by inspecting and , if necessary, blocking data packets that are considered harmful.

Top Security Testing Interview Questions :

Answer: Security testing can be considered as the most important in all types of software testing. Its main objective is to find vulnerabilities in any software (web or networking) based application and protect their data from possible attacks or intruders.

As many applications contain confidential data and need to be protected from being leaked. Software testing needs to be done periodically on such applications to identify threats and to take immediate action on them.

Answer: There are following seven attributes of Security Testing:


Answer: Two common techniques to protect a password file is- hashed passwords and a salt value or password file access control.

Answer: Two common techniques to protect a password file is- hashed passwords and a salt value or password file access control.

Answer: ISO/IEC 17799 is originally published in the UK and defines best practices for Information Security Management. It has guidelines for all organizations small or big for Information security.

Answer: URL manipulation is a type of attack in which hackers manipulate the website URL to get the critical information. The information is passed in the parameters in the query string via HTTP GET method between client and server. Hackers can alter the information between these parameters and get the authentication on the servers and steal the critical data.

Answer: HIDS or Host Intrusion Detection system is a system in which a snapshot of the existing system is taken and compared with the previous snapshot. It checks if critical files were modified or deleted then an alert is generated and sent to the administrator.
