Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
In various embodiments of the present invention, the wireless network includes, but is not limited to, a Wifi network. Fig. 1 is a flowchart of a method for improving wireless network access security according to an embodiment of the present invention, as shown in fig. 1, the method includes:
step 100: and judging whether the currently accessed wireless network is a safe network.
The implementation method of the step comprises the following steps: the user has previously identified on the mobile terminal one or more wireless networks, which are typically considered secure networks by the user, such as Wifi networks in the office or home. When a user accesses a wireless network, a mobile terminal to which the user belongs can judge whether the currently accessed wireless network is in one or more pre-marked wireless networks, and if the currently accessed wireless network is in the one or more pre-marked wireless networks, the currently accessed wireless network is judged to be a safe network; otherwise, if the currently accessed wireless network is not in the one or more wireless networks marked in advance, judging that the currently accessed wireless network is not the safe network.
Step 101: if the accessed wireless network is a secure network, setting the security level of the mobile terminal to be a first security level; otherwise, setting the security level of the mobile terminal as a second security level; the first security level is lower than the second security level.
In this step, setting the security level of the mobile terminal to the first security level includes:
the access rights of the pre-marked data are set to allowed and the rights of the application are set to allowed. Here, after the access authority of the pre-marked data is set to be allowed, the user can access the pre-marked data; after the permission of the application is set to be allowed, the external program and the background program can execute the operation of the related permission, such as reading the current position, reading the contact person and the like.
In this step, setting the security level of the mobile terminal to the second security level includes:
setting access rights of pre-marked data and/or setting rights of applications; setting access rights of the pre-marked data includes: the access right of the pre-marked data is set to one of the following two rights: forbidden or requiring interrogation; setting the authority of the application includes: the authority of the application is set to one of the following two authorities: forbidden or requiring interrogation; when the application authority is set to be forbidden, the external program and the background program can not execute the operation of the related authority, such as reading the current position, reading the contact person and the like, when the application authority is set to be inquired, the external program and the background program execute the operation of the related authority, need inquire the user, and can execute the operation of the related authority only after the permission of the user is obtained.
Step 102: and accessing the current wireless network at the set security level.
Specifically, the method comprises the following steps: when the security level of the mobile terminal is set to be a first security level, accessing a current wireless network according to the first security level; and when the security level of the mobile terminal is set to be a second security level, accessing the current wireless network with the second security level.
The present invention will be described in detail with reference to specific examples.
Fig. 2 is a flowchart of a first embodiment of a method for improving wireless network access security according to the present invention, as shown in fig. 2, the flowchart includes:
step 200: data is pre-marked on the mobile terminal and one or more wireless networks are identified.
In particular, the pre-tagged data generally refers to data that requires enhanced access control in an unsecure wireless network environment, such as but not limited to text messages, contacts, location information, pictures, video, sensitive material, and some important files. The above-identified wireless network generally refers to a wireless network that a user considers safe, for example, a Wifi network in an office or home, etc.
Step 201: when the current accessed wireless network changes, judging whether the newly accessed wireless network is a safe network, if not, turning to the step 202, otherwise, turning to the step 203.
In this step, when the currently accessed wireless network is not changed, the security level of the mobile terminal is kept unchanged, and whether the accessed wireless network is changed or not is continuously monitored.
Here, when the currently accessed wireless network is changed, if the newly accessed wireless network is in the one or more wireless networks previously identified, the newly accessed wireless network is a secure network, otherwise, when the newly accessed wireless network is not in the one or more wireless networks previously identified, for example, when the newly accessed wireless network is a strange Wifi network or a public Wifi network, the newly accessed wireless network is considered not to be the secure network.
Step 202: setting the security level of the mobile terminal to be a second security level according to the following modes: setting the access authority of the pre-marked data as forbidden and keeping the authority of the application unchanged; and accessing the current wireless network at the second security level and recording the current wireless network.
Here, after the access right of the pre-marked data is set to be prohibited, the external program or the daemon cannot access the pre-marked data, so that personal data of the user can be effectively protected, and the security of the user data in the non-secure network environment is enhanced. It should be noted that, when the application right is kept unchanged, the current application right is kept consistent with the application right set in the last time of accessing the wireless network.
Step 203: setting the security level of the mobile terminal to be a first security level according to the following modes: setting the access authority of the pre-marked data as allowed and the authority of the application as allowed; and accessing the current wireless network at the first security level and recording the currently accessed wireless network.
In this step, since the newly accessed wireless network is a secure network, after the access right and the application right of the pre-marked data are both set as allowed, the user can conveniently access the data and read the data related to the application right.
Fig. 3 is a flowchart of a second embodiment of the method for improving wireless network access security of the present invention, as shown in fig. 3, the flowchart includes:
step 300 to step 301 are completely consistent with step 200 to step 201, and are not described herein again.
Step 302: setting the security level of the mobile terminal to be a second security level according to the following modes: setting the access authority of the pre-marked data as forbidden and setting the authority of the application as forbidden or required to be inquired; and accessing the current wireless network at the second security level and recording the current wireless network.
Here, after the access right of the pre-marked data is set to be prohibited, the external program or the daemon cannot access the pre-marked data, so that personal data of the user can be effectively protected, and the security of the user data in the non-secure network environment is enhanced.
In this step, after the permission of the application is set to be forbidden, the external program and the background program cannot execute the operation of the related permission, such as reading the current position, reading the contact person, and the like; after the application authority is set to be inquired, when the external program and the background program execute the related authority operation, inquiring the user, and only after the user agrees, the related operation can be carried out; it can be seen that the setting of the authority of the application in this step can effectively protect the sensitive data of the user from being illegally read, and the like, thereby improving the security of the mobile terminal.
Step 303: setting the security level of the mobile terminal to be a first security level according to the following modes: setting the access authority of the pre-marked data as allowed and the authority of the application as allowed; and accessing the current wireless network at the first security level and recording the currently accessed wireless network.
In this step, since the newly accessed wireless network is a secure network, after the access right of the pre-marked data and the right of the application are both set as allowed, the user can conveniently perform operations of data access and related rights of the application.
Fig. 4 is a flowchart of a third embodiment of a method for improving wireless network access security according to the present invention, as shown in fig. 4, the flowchart includes:
steps 400 to 401 are completely identical to steps 200 to 201, and are not described herein again.
Step 402: setting the security level of the mobile terminal to be a second security level according to the following modes: setting the access authority of the pre-marked data to be inquired and setting the authority of the application to be forbidden or to be inquired; and accessing the current wireless network at the second security level and recording the current wireless network.
After the access authority of the pre-marked data is set to be required to be inquired, when an external program or a background program needs to access the pre-marked data, inquiring a user, and accessing the pre-marked data only after the user agrees; at this time, the access authority of the pre-marked data can be flexibly mastered by the user, and the user experience is improved while the data security is maintained.
In this step, after the permission of the application is set to be forbidden, the external program and the background program cannot execute the operation of the related permission, such as reading the current position, reading the contact person, and the like; after the application authority is set to be inquired, when the external program and the background program execute the related authority operation, inquiring the user, and only after the user agrees, the related operation can be carried out; it can be seen that the setting of the authority of the application in this step can effectively protect the sensitive data of the user from being illegally read, and the like, thereby improving the security of the mobile terminal.
Step 403: setting the security level of the mobile terminal to be a first security level according to the following modes: setting the access authority of the pre-marked data as allowed and the authority of the application as allowed; and accessing the current wireless network at the first security level and recording the currently accessed wireless network.
In this step, since the newly accessed wireless network is a secure network, after the access right of the pre-marked data and the right of the application are both set as allowed, the user can conveniently perform operations of data access and related rights of the application.
Fig. 5 is a flowchart of a fourth embodiment of the method for improving wireless network access security of the present invention, as shown in fig. 5, the flowchart includes:
steps 500 to 501 are identical to steps 200 to 201, and are not described herein again.
Step 502: setting the security level of the mobile terminal to be a second security level according to the following modes: setting the access authority of the data marked in advance and the read-write authority of the data marked in advance as required to be inquired, and setting the authority of the application as forbidden or required to be inquired; and accessing the current wireless network at the second security level and recording the current wireless network.
After the access authority of the pre-marked data is set to be required to be inquired, when an external program or a background program needs to access the pre-marked data, inquiring a user, and accessing the pre-marked data only after the user agrees; and simultaneously, after the user agrees, the external program or the background program can continuously inquire the read-write permission of the pre-marked data, the read-write permission of the pre-marked data is divided into read-only and read-write, and when the read-only permission of the pre-marked data is obtained, the pre-marked data can be read but cannot be modified. When the read-write right of the data marked in advance is obtained, the data marked in advance can be read, and the data marked in advance can be modified. Therefore, the access authority and the read-write authority of the pre-marked data can be flexibly mastered by the user, and the user experience is improved while the data security is maintained.
In this step, after the permission of the application is set to be forbidden, the external program and the background program cannot execute the operation of the related permission, such as reading the current position, reading the contact person, and the like; after the application authority is set to be inquired, when the external program and the background program execute the related authority operation, inquiring the user, and only after the user agrees, the related operation can be carried out; it can be seen that the setting of the authority of the application in this step can effectively protect the sensitive data of the user from being illegally read, and the like, thereby improving the security of the mobile terminal.
Step 503: setting the security level of the mobile terminal to be a first security level according to the following modes: setting the access authority of the pre-marked data as allowed and the authority of the application as allowed; and accessing the current wireless network at the first security level and recording the currently accessed wireless network.
In this step, since the newly accessed wireless network is a secure network, after the access right of the pre-marked data and the right of the application are both set as allowed, the user can conveniently perform operations of data access and related rights of the application.
