Five major security protection measures to crack mobile security

With the emergence of Mobile Information Technology, today's employees can use mobile communication terminals such as mobile phones, PDAs, and laptops to implement wireless management and e-commerce transactions on Internet platforms. People can achieve everything anywhere and anytime, and obtain information about the business operations of the Organization in real time without the limitations and restrictions of fixed cables.

It should be said that mobile information provides industry customers with tailored information solutions and services of "One access, one network service, one settlement, this will greatly reduce the operation and management costs of the user unit, rapidly improve the market response of the user unit, and significantly enhance its comprehensive competitiveness.

Therefore, informatization is an important tool to promote economic and social development, and network security is the fundamental guarantee for realizing the effectiveness of informatization. However, there are still many problems and dilemmas in China's mobile information system. One of the biggest problems is security. Security issues have always been a hard nut to crack in Mobile informatization. Mobile informatization requires special attention to the security of wireless data channels.

In September 1 last year, a virus named Phage broke out in Europe and America, causing a panic. Phage sets the attack target to Palm OS. Phage attacks the operating system of Palm handheld computers and causes them to be infected. As a result, many mobile phone programs are damaged. In addition, Phage will try to disable and delete all data on mobile devices, seriously damaging wireless networks of many mobile phone users and enterprises in Europe and America.

After that, a worm named Timofoniac quickly spread through email and enters the Spanish cellular phone network. It often calls prank calls and leaves text messages on the phone. Experts predict that more viruses and worms will spread to mobile devices such as mobile phones in the future.

My opinion is that in the current environment, the popularity of enterprise wireless applications has gradually increased, but many enterprises still cannot keep up with their security defense methods. Therefore, we still need to work hard. This mainly includes five aspects.

First, do a good job in information security management and review, and set a single console to centrally manage all desktop computers, laptops, handheld devices, and USB flash disks, seamless and automatic encryption of sensitive data on all mobile endpoints and external media to ensure the security of unit data. At the same time, enterprise network administrators need to provide user verification, controlled port access, and application restrictions, and implement data control for lost or stolen devices to prevent further expansion of losses.

Second, perform security authentication on the internal web pages that are accessed by wireless networks, and strengthen firewall, intrusion detection, and vulnerability scanning in the real network environment so that the hosts inside the user's organization transaction are fully protected, to ensure the security of data and the legal and confidential access of personnel. In addition, enterprises need to provide encrypted management of digital certificates to accurately determine whether the WLAN is intruded and whether the packets contain viruses. In addition, for mobile features, VPN can be used to solve security problems in mobile Internet.

Third, build an enterprise's mobile data security protection system. The system needs to be able to automatically detect, review, and control all mobile endpoints connected to the network, including unauthorized endpoints. The system should support simple and comprehensive deployment of mobile security, and automatically implement protection mechanisms for the entire environment to prevent unauthorized access to multi-user operating systems, while data recovery must be fast and reliable.

Fourth, the mobile data security system must provide automatic and real-time security policies and software updates to quickly block security vulnerabilities, comply with regulations, and ensure the efficiency of mobile employees, access to encrypted data should be isolated from access to the operating system. At the same time, the entire system must provide a single management console for mobile security control, review and reporting, and can be used on various types of mobile and external storage devices, administrators can control, automatically execute, and update security policies for all mobile endpoints.

Fifth, for mobile operators, in addition to increasing the qualification review on the sms sp, it is also important to continuously upgrade the security of their information transmission networks. For mobile business service providers, we should constantly increase our sense of responsibility for ensuring the security of customers' information, provide mature products and solutions for user organizations, and continuously conduct security tests and function upgrades, this gives users a real sense of peace of mind.

Of course, when designing security protection for wireless devices, we must consider the features and limitations of wireless network communication. We cannot copy the experience and technology of traditional desktop computers.

In general, mobile information security protection must be strategic and cover the entire user unit. Any security solution must be able to process all parts of mobile data security while allowing users to work anytime, anywhere, minimize the risks faced by user organizations, reduce the total cost of ownership, and improve the efficiency and competitiveness of users.
