Research on the Security of Android7. 1

With the popularity of mobile Internet, Android has become the most popular mobile device operating system in the world. However, the popularity of Android also means that it has become the target of hackers and malware attacks. Therefore, the security performance of Android system has always been a topic of great concern. So, how about the security of Android 7. 1 system?

Security update

Android 7. 1 introduces a series of updates to enhance its security. One of the most important items is "platform signature enhancement", which aims to make the system more secure against the attack of root's high-risk privileges. In addition, the latest system has enhanced the support for Transport Security Protocol (TLS), enabling applications to use higher-level encryption to protect data transmission and ensure the privacy and security of user data.

Find a loophole

In Android 7. 1 system, Google fixed some security vulnerabilities, including one that allowed attackers to share user data across processes by using malicious software. In addition, Android 7. 1 contains more code encryption measures and defense measures against multiple attacks. All these have improved the security performance of the system and provided better data security protection for users.

Application rights management

Android 7. 1 also introduces stricter application rights management to help users better control the application rights. For example, an application needs to request all necessary permissions when it is installed. If the user is not authorized, the application will not be installed. At the same time, this new system can also create its own virtual file system for different applications to prevent applications from stealing and tampering with user data. Android 7. 1 Through such measures, the control and protection of users' own data have been strengthened.

abstract

To sum up, Android 7. 1 has been modified and updated as much as possible to enhance the security of the system and provide users with better data protection and control measures. However, the security of Android system will never be perfect. Users should pay attention to improving their own security awareness, keeping the application upgraded, backing up data regularly, and resolutely deleting applications with potential security risks, so as to obtain more comprehensive data security protection.
