Security audit system of smartphone and smartphone applications has become a big necessity in today’s world of technology and science where everything has become mobile and wireless. This type of auditing involves a technical security audit of all mobile apps and the web server services as a whole. Smartphone auditing involves testing of all user inputs, testing of business logic, testing of digital signing, securing authentication between the mobile application and web services etc.
There are different methods used for security auditing, some of which we shall discuss below:
Using OWASP Testing Method for Auditing
One most common mobile application security audit testing is the OWASP mobile security project. This is a centralized resource which aims to help developers and security teams by providing them the resources they need to create and maintain secure mobile applications. The basic objective is to categorise mobile security risks and offer developmental controls that can reduce or prevent their impact of dangers. It focuses on protecting and identifying sensitive data on the device, handling password securely, implementing user authentication and authorization correctly, keeping back-end services and the platform server secure, securing data integration with third-party services and many more such mobile controls.
Using REST/SOAP Security Audit
These are basically web services security audit performed on the audit of mobile applications annual security as well. Both REST and SOAP security audit is performed as a “black box” security audit which mean there is no knowledge of XML schema definition (XSD) / Web Services Description Language (WSDL) schemas, credentials, etc. and also as a “white box” security audit where there is knowledge of API and provided credentials . In both cases, mobile testing is performed as per the guidelines of the OWASP testing guide. Such methods are beneficial for companies that operate or develop their own mobile applications
Using Cloud-Based Security Solution
This is yet another useful technique of auditing security for android smartphones. In this testing method, a cloud-based security system is undertaken for collection, analysis, visualization, and correlation of application logs, statistics which can help in identifying abnormal application and network behaviour on the mobile device. If any kind of unwanted behaviour is detected, an alert is sent to the mobile device for appropriate remedial action. In case, there is abnormal network traffic, then there is an implementation of firewall rules like as NETFILTER firewall which blocks the unwanted network traffic. In cloud-based security, there is also a web interface which helps to see logs and all data collected from the device.
