Use gsm interceptor to detect login attempts


Use gsm blocker to detect login attempts

  You can view blocked IP addresses by logging into the Service Center with the necessary permissions.This random number is sent to the terminal, and the above process is completed in the authentication center (AUC, authentication center).You should also use the Service Center to manage blocked IP addresses.On the terminal side, the user equipment calculates the authentication response number SRES according to the received RAND and in combination with the IMSI.There are four main security measures adopted by the 2G system: preventing air interface information Encryption and decryption technology to be eavesdropped by attackers; authentication and authentication technology to prevent unauthorized users from accessing illegally; temporary mobile user identity update technology to prevent attackers from stealing user ID codes and location information; Continue to use device authentication techniques.

  In Service Center, gsm jammer select the IP address you want to block.After the request, the base station first generates a random number (RAND, random number), and then uses the encryption algorithms A3 and A8 to calculate the random number and the root key together to obtain the expected authentication response number (SRES, signed response).Detecting login attempts can be a great way to protect your network and company.If the two are consistent, the authentication succeeds; otherwise, the authentication fails.Compared with the first-generation analog communication, the second-generation communication system using digital communication has added many security capabilities, which made 2G the most secure mobile communication system at that time.

  In the first-generation analog communication system, due to almost no security mechanism protection, security problems such as wiretapping of user calls, theft of numbers, and theft of communication resources emerge in an endless stream, which seriously damages the rights and interests of legitimate users and operators.However, it's not enough to just install the software and keep your network safe.Then the terminal sends the SRES to the base station through the air channel, and the base station compares the authentication response number SRES sent by the user with the authentication response number calculated by the core network.

  Capacity constraints, the second generation of mobile communication technology came into being.Authentication technology is to prevent unauthorized users from accessing the GSM system The most common authentication in the second generation mobile communication network occurs between the user and the base station, and the authentication procedure in the GSM system is defined in GSM09.02 MAP.The brief process is as follows: when the mobile terminal wishes to connect to the network in the visited place, the terminal initiates an authentication request to the visited network, the VLR forwards the request to the home location register (HLR, home location register), and the home core network receives the request.
