This page provides essential documents related to mobile network cybersecurity, including guidelines for protecting voicemail systems and VoLTE communication. Operators can explore known VoLTE threats and how to implement effective mitigation strategies.<\/p>\n\n\n\n<p>The GSMA offers resources for securing UICC credentials, which are key to safely exchanging sensitive information between mobile network operators and UICC vendors. For those transitioning to virtual infrastructures, the Network Function Virtualization (NFV) guidelines examine the security risks tied to virtual network functions. These documents provide insights into potential risks and steps to protect mobile networks. By staying informed with best practices, operators can minimise the risk of cyberattacks.<\/p>\n\n\n\n<style>\n    table {\n        width: 100%;\n        border-collapse: collapse;\n    }\n    th {\n        background-color: #dc002b; \/* Custom red color *\/\n        color: white;\n        padding: 8px;\n        font-weight: bold; \/* Make column headers bold *\/\n    }\n    td {\n        padding: 8px;\n        text-align: left;\n    }\n    tr:nth-child(odd) {\n        background-color: white; \/* White for odd rows *\/\n    }\n    tr:nth-child(even) {\n        background-color: #f1f1f0; \/* Light grey for even rows *\/\n    }\n    img.download-icon {\n        width: 16px;\n        height: 16px;\n        vertical-align: middle;\n    }\n<\/style>\n\n<table>\n<head>\n    <tr>\n        <th>Document<\/th>\n        <th>Description<\/th>\n        <th>Access<\/th>\n    <\/tr>\n<\/head>\n<body>\n    <tr>\n        <td>\n            <a href=\"https:\/\/www.gsma.com\/solutions-and-impact\/technologies\/security\/gsma_resources\/sg-20-voicemail-security-guidelines\/\" target=\"_blank\" rel=\"noopener\">\n                Voicemail Security Guidelines (SG.20)\n            <\/a>\n        <\/td>\n        <td>The Voicemail Security Guidelines provide guidance for operators on the management of personal identity numbers (PINs) and passwords used to authenticate users to obtain secure access to voicemail services.<\/td>\n        <td>\n            Public \n            <a href=\"https:\/\/www.gsma.com\/solutions-and-impact\/technologies\/security\/gsma_resources\/sg-20-voicemail-security-guidelines\/\" target=\"_blank\" rel=\"noopener\">\n                <img decoding=\"async\" class=\"download-icon\" src=\"https:\/\/www.gsma.com\/solutions-and-impact\/technologies\/security\/wp-content\/uploads\/2024\/09\/GSMA-red-download-icon_100x100_02.09.24.png\" alt=\"Download icon\">\n            <\/a>\n    <\/tr>\n    <tr>\n        <td>\nSMS Blasters Briefing Paper (FS.67)\n        <\/td>\n        <td>\u200b\u200bThis PRD educates MNOs on the threat posed by SMS Blasters, which are false base stations used by fraudsters to bypass network-side SMS filtering and deliver phishing messages directly to mobile users.
