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 crack...

A network operating system is a software application that provides a platform for both the functionality of an individual computer and for multiple computers within an interconnected network. Basically, a network operating system controls other software and computer hardware to run applications, share resources, protect data and establish communication. Individual computers run client operating systems, while network systems create the software infrastructure for wireless, local and wide area networks to function. Basic Operating Features Network operating systems support the basic underlying operating features of networks. These include support for processors and the various protocols that allow computers to share data. Many network operating systems can detect hardware within the system to allow for asset discovery within the network. Also, network operating systems support the processing of other software applications that run on both individual computers and within the net...

Ransomware is malicious software that infects your computer and displays messages demanding a fee to be paid in order for your system to work again. This class of malware is a criminal moneymaking scheme that can be installed through deceptive links in an email message, instant message or website. It has the ability to lock a computer screen or encrypt important, predetermined files with a password. Examples of Ransomware Scareware is the simplest type of ransomware. It uses scare tactics or intimidation to trick victims into paying up. It can come in the form of fake antivirus software in which a message suddenly appears claiming your computer has various issues and an online payment is necessary to fix them! The level of this type of attack varies. Sometimes, users may be bombarded with endless alerts and pop-up messages. Other times, the computer will fail to work at all. Yet, another type of ransomware can impersonate a law enforcement agency by opening up a page t...

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:...

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 ...

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 ser...

Cyber security or information technology security are the techniques of protecting computers, networks, programs and data from unauthorized access or attacks that are aimed for exploitation. Description: Major areas covered in cyber security are: 1) Application Security 2) Information Security 3) Disaster recovery 4) Network Security Application security encompasses measures or counter-measures that are taken during the development life-cycle to protect applications from threats that can come through flaws in the application design, development, deployment, upgrade or maintenance. Some basic techniques used for application security are: a) Input parameter validation, b) User/Role Authentication & Authorization, c) Session management, parameter manipulation & exception management, and d) Auditing and logging. Information security protects information from unauthorized access to avoid identity theft and to protect privacy. Major techniques used t...

If you're having trouble signing in to your Microsoft account, there could be a few different reasons for that – like you can't remember your password, have two-step verification turned on, or are travelling or using a new device. Here are some suggestions to help you get back into your account as quickly as possible. First, try the easiest options: If you remember your password but it isn’t working, make sure that Caps Lock is turned off and that your email address is spelled correctly. Clear your browser history, or try signing in to your account from a different internet browser. If these don't help get you back in to your account, try resetting your password or see if one of the other scenarios below applies to you and give them a try. If you forgot your microsoft account password and can't remember , reset it Follow these steps to create a new one: Go to the Reset your password page. Choose the reason you need your password reset, then click Next. Enter the em...
