  In the past, wired networks were considered to be far more secure than wireless networks. Today, however, wireless networks are as secure as wired networks, so long as they are properly configured. According to TechTarget, "When comparing wireless vs. wired security, securing a wireless network is even more important than securing a wired network for one simple reason: Accessing a wireless network does not require physical access to a network jack or cable, as does accessing a wired network. Wireless networks use radio transmissions to carry data between end users and the network and it is difficult to contain those radio waves. Therefore, it’s possible for someone to sit in your office building's lobby or parking lot and eavesdrop on wireless network communications." How can MSPs safeguard wireless networks against unauthorized access? There are several tools that MSPs and IT administrators can use to protect the wireless networks they manage, including: Encryption. En...

  Managing a corporate network is becoming harder as it becomes larger and more complex. ii. Network management, it includes not only components that transport information in the network, but also systems that generate traffic in the network. iii. The systems could be hosts, database servers, file servers, or mail servers. In the client-server environment, network control is no longer centralized, but distributed. iv. Computer and telecommunication networks are merging fast into converged network with common modes and media of transportation and distribution. As in the case of broadband networks, the IT manager needs to maintain both types of networks. v. Thus, the data communications manager functions and telecommunication manager functions have been merged to that of the IT manager. vi. With the explosion of information storage and transfer in the modern information era, management of information is also the responsibility of the IT manager, with the title of CIO, Chief Informati...

    If you look under the hood of an intent-based networking system (IBNS), you’d be crazy not to see it as the future. It’s really smart, really safe, and hardware agnostic — basically fixing most of the annoying little problems while satisfying the big requirements for the largest data centers. Luckily, it’s just the future. It’s here now (albeit in a limited capacity). But that’s about to change. Intent-based networking systems (IBNS) will inspire a major shift in how networks are managed. Here are things you should know about intent-based networking. Automating Processes and Keeping Data Secure…Naturally First off, what are we talking about? What exactly is intent-based networking? A common analogy used to explain the technology is a self-driving car. You put in the destination, and instead of manually driving, the car makes all the turns, lane changes, starts at green lights, and stops to avoid collisions for you. All the decisions and granular moment-by-moment adjustment...

  Sometimes you end up with a great many Windows domain passwords that need cracking – either because you have compromised the domain controller and exported them yourself, or because the client has asked you to perform a password audit and has supplied the database to you themselves. As you know, LM hashes are insecure, and there is a very good way of cracking these (Ophcrack). However, there will also be passwords that cannot be cracked using the standard tables, or maybe the LM hash is not present in the dump at all. In this case, we’ll need to attack the NTLM hash with another tool – in this case a GPU cracker known as Oclhashcat. In this case we have a large (something like 6,000 entry) pwdump format file, with LM and NTLM hashes. Because the LM hashes have various weaknesses in the cryptography, we can crack a lot of passwords using Ophcrack – but in some cases only NTLM hashes are present. In this case we can use a hybrid approach. know more :  lm password cracker

How can MSPs safeguard wireless networks against unauthorized access? There are several tools that MSPs and IT administrators can use to protect the wireless networks they manage, including: Encryption. Encryption protects the confidentiality of data transmitted via the Internet or a computer network by scrambling the original message with a large digital number (also known as a key). Wireless networks support two types of encrypt...

  A LAN (Local Area Network) is the most basic form of infrastructure that allows communication between two or more computers. A LAN can be constructed with or without servers and is typically restricted, through the limits of network equipments, by physical location. Any system that allows communication between multiple LAN is called a WAN (Wide Area Network), of which the biggest existing one is the World Wide Web, also known as the Internet. Networking Hardware Networking hardware is a switch that allows a computer to communicate to more than one other computer simultaneously. It can be physically wired through network cables or otherwise (e.g. Wi-Fi). A computer participating in the LAN similarly requires the correct equipment such as network adapters installed. Wired network provides better speed and security compared with wireless. A LAN can also consist of both. Depending on the number of clients in the LAN, functionality and complexity, multiple switches, routers and server...
