Security protection method and device, terminal equipment and storage medium

The invention discloses a security protection method and device, terminal equipment and a storage medium, the security protection method relates to the field of network equipment protection, the security protection method identifies a scanning source communicating with a protection target, and if the scanning source is identified as a scanning tool, the security protection is carried out. The method comprises the following steps of: if the scanning type tool is not in a preset white list, establishing communication connection between the scanning type tool and a protection target, judging whether the scanning type tool belongs to the preset white list, and if the scanning type tool is not in the preset white list, blocking a subsequent communication session between the scanning type tool which is not in the preset white list and the protection target. According to the method and the device, the problem that normal work of a protected target is influenced while an attack exposure surface is reduced is solved,
