How to conduct mobile app security assessment and detection technology analysis

Due to the increasingly developed network technology today, there are also many hidden dangers in the security of Android APPs, which require our constant attention to improve their security. Based on the security of system programs, system data, basic services, and application vulnerabilities, people continue to improve and form a more secure, stable, and complete mobile APP monitoring system to ensure the security of mobile APPs. It will serve as the primary line of defense for "malicious harm", that is, the first line of defense. This will also increase the researchers' consideration of APP security assessment when developing mobile APPs, and help the development of mobile APPs to be better and safer.

Key Points of Protection for the New Version of Level Protection Evaluation of Mobile App

According to the latest level protection mobile Internet security expansion standard, the new standard is based on mobile Internet The level of technology is the main guarantee object to ensure the overall object level. There are no fixed requirements and goals for mobile terminal systems, application systems, and wireless networks, that is, they are not required to be rated separately. The new standard must not only meet the previously proposed level of protection standards, but also meet several more important issues such as the application of mobile terminals and APPs in daily life, the physical and environmental security of wireless networks, and the application and data security of APPs. Technically, improve the security of mobile APP. In addition, new goals and requirements have also been formulated for the management level, such as safety management methods and methods, safety management systems, safety management of enterprises and employees, safety construction improvement, etc. related requirements.

Security Detection Research System of Mobile APP

Due to the accelerating development of network technology, many criminals have taken a fancy to platforms such as the Internet and carried out some illegal activities. , so mobile APPs will have many security problems, and criminals will use such loopholes to quickly defraud users and other illegal activities. Many users do not know that APPs have such security loopholes when using them, so many Users sometimes fall into a trap and don't even know it. At this time, it is necessary to establish a sound APP security testing and research system, and the security vulnerabilities of each mobile APP must be solved, so that the user's safety can be guaranteed to a certain extent, and users can use the APP with peace of mind.

The Jiwei Security Mobile Application Security Level Assessment System is an automated security detection service for enterprises and individual developers. It supports multiple APP security assessment tests for Android application APK packages, including code protection, dynamic For 80 risk points such as defense, local data, network data, and malicious vulnerabilities, static analysis and dynamic analysis detection (real machine detection) can be completed in an average of 10 minutes, and visual online reports and offline reports in Word format can be generated. Help users conduct security testing before releasing the APP to avoid potential security issues causing economic losses.

Data security

(1) Storage security detection

The internal important information of mobile APP is very easy The main reason for the leakage is that there is a problem with the way its information is stored, which results in most people having access to internal permissions. As a result, important internal information is easily leaked.

(2) Resource file tampering

There are many pirated APPs or plagiarized APPs on the Internet. This is because the resources in the original mobile APP have not been A series of security protection measures are directly available to users. Many criminals take advantage of such loopholes and secretly modify the genuine APP resources to turn it into a pirated APP.

Business security

(1) Certificate monitoring and detection

In terms of ensuring mobile APP business security, Ensuring the security of mobile APP certificates is a very meaningful method. If the APP's certificate will not be stolen, it can ensure the security of the user's account, information and password. To ensure the security of the certificate, you only need to encrypt the information in the certificate.

(2) Processing and detection of abnormal events

A good mobile app should have the ability to handle and detect exceptions when encountering them. Once an abnormal situation occurs, it is not only required to be extremely sensitive to detect it and capture it, but also to record it after capturing it, or to transmit it to the server that performs exception analysis, and the server analyzes it.

Vulnerabilities in program applications

(1) Virus detection

Every mobile APP must be tested before it is put on the shelves APKs all need to undergo specialized virus testing.

(2) APK Pathological Decompilation Zen Vulnerability

Conduct APK static decompilation detection on mobile APP to detect whether there are compilation vulnerabilities. Many decompilation tools, such as apktool, decompile it into smali code. If protection measures are not set for smali code, the software will have many security problems, such as the software will be cracked, some bad code will be inserted, and even the advertiser's ID will be replaced, etc.

(3) Database injection vulnerability

Detect database injection vulnerabilities in the APP and discover its adverse effects. In some cases, for example, when setting the read and write permissions of the Content provider, improper settings are made, and the filtering of SQL statements is omitted. These problems will cause hidden dangers in the mobile APP database. If a malicious person attacks it, the user's account name, password and other sensitive data are in danger of being leaked. It will also cause abnormalities when the user performs queries, and may even cause the application to crash.

(4) a1lowBackup security vulnerability

Detects the risk of data unauthorized backup of mobile APP. Some systems provide specialized functions for data backup and recovery, such as Android API Level 8 and above systems. If this function is risky, attackers may recover data on other terminals, leading to the leakage of sensitive information such as user chat information. As for applications involving money transactions, others can attack them to perform a series of operations such as stealing deposits and making malicious payments.

(5) There are vulnerabilities in the execution of remote code of Web View

Detect whether there are vulnerabilities in the remote code execution of Web View in the APP. Appear. Basically, there are some remote code execution vulnerabilities in previous versions, such as Android API level 16, or even previous versions will have such problems. This kind of vulnerability occurs because the program is using Web View. add Java script Interface. This method fails to implement normal restrictions, and this gives those who attack remotely the opportunity. They can use the Java Reflection API method to completely expose some java function interfaces of the mobile APP, making them Some illegal operations can be completed using this interface.

(6) Operation security of data memory

Detect whether the mobile APP has any problems with dynamic debugging of the code. Some human operations or some malicious programs use this dynamic debugging technology to conduct a series of eavesdropping and tracking on the program while the program is running, so as to obtain some data information of the mobile APP and steal information about the APP. Some private information of users, this is the dynamic debugging vulnerability of the code in Android C layer.
