For example, techniques are provided for preventing malicious attacks via a user equipment deregistration process. In one example, a method comprises sending a deregistration request message from the given user equipment to a communication system to which the given user equipment is registered, wherein the deregistration request message is security-protected and comprises a temporary identifier assigned to the given user equipment. By not sending the deregistration request message with a subscription concealed identifier, the given user equipment prevents a malicious actor from succeeding with a deregistration attack replaying the subscription concealed identifier. Furthermore, by ignoring a deregistration request message with a subscription concealed identifier, an access and mobility management element of the communication system prevents a malicious actor from succeeding with a deregistration attack replaying the subscription concealed identifier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Prevention of malicious attacks via user equipment deregistration process in communication system","description":"Improved security management techniques between user equipment and a communication system are provided.
