Security Concerns In The Telecoms Industry

 Telecommunication and network security is one of the most technical domains of the CISSP credential because it requires an understanding of network infrastructure, methods of communication, formats for transporting data, and measures taken to secure the network and transmission. The network is the vital link connecting information resources to users. Thus, this domain focuses on the design and architecture of the network and its components to prevent the disruption of data flow and intrusion.

The key components of this domain are:

Confidentiality
  • Network security protocols
  • Network authentication services
  • Data encryption services
Integrity
  • Firewall services
  • Communications security management
  • Intrusion detection services [and intrusion prevention systems]
Availability
  • Fault tolerance for data availability (backups, redundant disk systems)
  • Acceptable logins and operating process performance
  • Reliable and interoperable security processes and network security mechanisms3

what are the causes to Improve Network Security

  Companies that face concerns about the electronic information they compile, analyze,and share to drive their business need comprehensive solutions for improving network security. With concerns about network security running at an all-time high, along with the limited number of IT personnel capable of addressing them, an increasing number of companies are realizing how outsourcing to managed service providers (MSPs) can strengthen their security posture, reduce hassles and save money. MSPs looking to cash in on these opportunities face their own challenges of how to provide premium offerings to the broadest markets and verticals without having to balance or customize offerings for each client’s unique service and compliance requirements. They also need a way to differentiate themselves from peers and competitors who are also trying to get a piece of this crowded and lucrative pie. find more :   security engineer C

History of Network Operating Systems

Nowadays, practically every personal computer is connected in one form or another to a network. There exists of course the biggest network of all —the Internet— but several other types of smaller networks like LANs (local area networks) and enterprise networks also exist. Network operating systems (NOS) serve as gatekeepers to data and applications on all manner of these networks. Network operating systems don't differ too much from the single-processor operating systems almost every computer user is familiar with, says Andrew Tannenbaum in his book "A History of Operating Systems", but they have their own unique, fascinating history. Birth of Networks The concept of data communications between computers began in the late 1960s and early 1970s, when researchers began developing a way of connecting computers and exchanging information by way of packets of data. Soon, the concept of a local area network (LAN) took hold, replacing the previous model of a central computin...
