  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 :   network and security engineer jobs

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 computing no

  When building a local network, you probably use a mix of computers, including Windows PCs and Apple Macs. Though OS X and Windows are built quite differently, they can be networked through file sharing services built into each operating system.  On Macs, you turn file sharing on in the System Preferences menu. Then, using a Windows computer, you can connect to those shared folders by using the local IP address of the Mac computer. Step 1 Turn on both the Mac and PC computers, and ensure that they are connected to the network. Step 2 Click the Apple icon, then "System Preferences" and then "Sharing" on your Mac. The Sharing window appears. Step 3 Select "File Sharing" from the services pane on the left-hand side of the window. Step 4 Write down your Mac's IP address. It is located under the "Windows Sharing: On" section of the file sharing window, denoted by "afp:\192.168.1.102" where "192.168.1.102" represents your Mac&#

  Route reflectors are networking routing components specific to border gateway protocol, commonly known as BGP. Route reflectors are an alternative to the full-mesh requirement of internal BGP (IBGP), and act as a focal point for IBGP sessions. Because route reflectors can propagate IBGP routes to other IBGP peers, a full mesh of IBGP peers is not necessary. The concept of a route reflector is consistent across IP version 4 as well as 6, but the topology used here refers to IPv6. In the diagram below, the red dotted lines represent external BGP relationships, while the blue dashed lines reflect the internal neighborships within the AAS. The Role of Route Reflectors If R3 follows the rule and does not advertise the prefix to its internal neighbors, R4 and R5 will not learn it. The purpose of route reflectors is to fix that problem. To do so, the route reflector simply instructs R3 that, when it receives an advertisement from an IBGP neighbor (in this case, R2), it should break the rule

    The components used to establish a local area network (LAN) have a variety of functions. The common unifying theme among them is that they facilitate communication between two or more computers. LAN components are configurable in a variety of ways, but a LAN always requires the same basic components. Network Cards At the most basic level, a network card is a component that allows the computer to communicate across a network. This component is frequently built into the motherboard of today's computers, but it can also be a separate card for use in a PCI slot, or part of an external unit that connects to the computer via a USB port. Network cards are further categorized according to whether they operate on wired or wireless networks. However, some cards do support both wireless and wired networking. Network Cables Network cables are the physical lines used to carry information between computers in a wired LAN. The cables are labeled by their category and are commonly referred to

  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 know more :  secur
