Shulou(Shulou.com)06/01 Report--

Many companies have their own APP, including Android and iOS, have their own APP applications. With the rapid development of the Internet, APP security also affects the business development of the whole company. Some time ago, the customer's APP was attacked, the data was tampered with, and the payment address was modified into the attacker's own, resulting in heavy losses. Find our SINE security to do APP security protection through the introduction of friends. We conduct penetration testing, vulnerability detection, and other omni-directional security testing on customer APP. Through nearly ten years of APP security maintenance experience to sum up, how to do a good job of APP security to prevent attacks.

According to our research on SINE security, we have conducted security tests on most APP applications in China, and found that 40 percent of APP uses http for data transmission, including users' login accounts and passwords, 22 percent of users use SSL certificates to encrypt data transmission, and 80 percent of APP applications use plaintext to store data on mobile phones. 75% of the APP are not reinforced, so it seems that there are security risks in the whole APP application of the mobile Internet. With the popularity of Mobile 5G, the situation of the Internet of everything is coming, and the security of APP plays an important role. No matter how fast the security is, the leakage of user information and the occurrence of data tampering are fatal to any enterprise.

How to test and reinforce the security of APP?

We SINE security here to share with you in detail, hoping to help more APP application enterprises. Most of the APP uses the server as the backend, so while we strengthen the APP security, we should also do a good job in the security of the server, including the security of the windows,linux system, set the port of the server, implement the port security policy, only allow the App side to communicate with the server, refuse any external IP access and scanning, and also do security authentication for the server's SSH,mstsc remote login. Conduct a comprehensive penetration test on the server and comply with the information security level protection. Remote connection with the server can enable IP security policy and add IP to the whitelist separately. For example, Ali Cloud CVM can be used in the Ali Cloud console, port security, and release IP separately.

Website security is also called web security, many APP are embedded in the website to use some interfaces to call, convenient and fast at the same time, it is also necessary to strengthen the website security, including website vulnerability detection, code manual security audit, website Trojan back door detection and clearance, website tamper-proof deployment, website log security analysis, regular website security inspection and other security work. If you don't know much about security reinforcement, you can also find a professional website security company to deal with, domestic SINESAFE, Green League, Qiming Star, are quite good, the website needs to enable https protocol access, through the SSL certificate to encrypt APP data transmission.

APP code encryption and confusion, APP must encrypt the code while developing, encrypt the code to the core functions, including some payment functions, carry out manual security audit on every piece of code in APP, detect APP loopholes in advance and repair them, prevent attackers from downloading APK to reverse code decryption operations, do AES encryption to data transmission, and mix multi-level encryption and decryption. To prevent tampering with data through the POST to API interface through data capture packets, to achieve the purpose of tampering with data. Some APP has some logical functions, which are realized through APP data capture packages. Some APP developers do not make strict security judgments and restrictions on some permissions, resulting in the ability to bypass and directly perform operations on other accounts, such as account password modification, data modification, and so on.

Do security authentication for APP user login, enhance the security of APP interface, increase identity security authentication, including face and SMS verification code, and then combined with mobile device information to secure authentication to prevent malicious login. The two-way encryption measure of data transmission is done in the payment interface, the payment gateway is bound with APP server IP, the data is encrypted and transmitted by SSL, and the data is encrypted by AES.

APP operators of many companies attach great importance to the security of APP. APP security can ensure the security of the entire company's business. During the APP development phase, APP should be tested, including APP security penetration, penetration testing services, and reverse cracking protection of APP. If your APP data is tampered with and user information is leaked, there must be loopholes in APP. Find a professional penetration testing company to help you find the loopholes in APP. Prevent the expansion of attacks and minimize losses. Domestic professional penetration testing companies, such as SINE Security, Qiming Star, Green Alliance, convinced, are more professional. APP security should start from many aspects, such as server security, website security, APP code, transmission encryption, interface security and so on, to enhance the security emergency response ability of the company security team.
