Telecommunications and Network Security

The CIA TRIAD The following is how to preserve the CIA triad in the telecommunications and network security domain: Confidentiality – Network Security Protocols – Network authentication services – Data Encryption Services Integrity-Firewall Services-Communications Security Management-IDS's Availability-Fault tolerance for data availability, such as backups and redundant disk systems-Acceptable log-ins and operating process performance-Reliable and interoperable security processes and network security mechanisms Ill structured security mechanisms, over engineered, and poorly designed security systems can also impact the performance of a network REMOTE ACCESS SECURITY MANAGEMENT Several current remote computing technologies exist-DIAL UP, SYNC, & REMOTE INTERNET CONNECTIVITY (different ways to connect) DSL ISDN Wireless computing (mobile phone ,pdas) Cable modems-SECURING ENTERPRISE AND TELECOMMUTING REMOTE CONNECTIVITY(different ways to authenticate) Securing external connections (VPNs, SSL, SSH etc..) Remote access authentication systems (radius and tacacs) Remote Node authentication (PAP and CHAP)-REMOTE USER MANAGEMENT ISSUES Justification for and the validation of the use of remote computing systems Hardware and software distribution User support and remote assistance issues
