Hoe does ransomware works

  Now you know how to prevent ransomware, but what if you have already become the victim of a ransomware attack? In the event of a ransomware attack, it is important to know what to do. Here are some simple steps to follow to minimize damage. Isolate your computer If you experience a ransomware attack, the first thing to do is to disconnect from any networks and the internet. Disconnecting in this way, isolates your computer and minimizes the chance of the ransomware infection spreading to other computers. Never pay the ransom Do not pay any ransom demanded by the cybercriminals carrying out the ransomware attack. Like a real-life hostage situation, it is best not to negotiate with cybercriminals. Paying the ransom will not guarantee the return of your data — after all these individuals have already manipulated your trust. Caving in and paying also encourages this sort of crime. The more people that pay the ransoms, the more popular ransomware attacks become. Also find :  L an manager

Telecommunication and Network cyber Security solutions

  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 :  3 dom

Mac to a PC on a Local Network

  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

BGP Route Reflectors

  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

Efficient Password Cracking

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. find more :  l m hash cracker

Windows System32 CCM

  CCM, located in Microsoft Windows' System32 folder, stands for Change and Configuration Management. It's a folder created to store temporary files for client installations as a part of the Systems Management Server (SMS) of Microsoft, which is responsible for deploying system-wide installations and updates. Background SMS was Microsoft's enterprise management software that tracks hardware and software inventories, deploys software applications and updates and manages any software changes in a network environment. By 2007, this has become System Center Configuration Manager, which essentially performs the same tasks as SMS. Process SMS or SCCM centralizes the process of software installation into one management application. When a new software or update needs to be deployed, it creates the CCM folder in all computers until the installation or update finishes. The CCM folder contains the Advance Client Installer (ccmsetup.exe), which is responsible for initiating the instal

uses of cloud services

  When it comes to cloud services and software-as-a-service (SaaS), we're all familiar with the usual cloud providers. But for small businesses and larger enterprises, there's a huge world of opportunity and available resources beyond those best-known cloud storage and cloud computing services: Google, Dropbox, Salesforce, Amazon and Microsoft. In this guide to services for business, we're looking at 24 incredibly valuable services that solve real-world business problems. A few of you may have heard about before. Many may be new to you. All are capable of providing nearly instant benefit -- without you having to make any infrastructure investment whatsoever. Often, these bottlenecks aren't because a higher-up didn't actually want the project to go through, but simply never got around to signing off. The approval email might have gotten lost or, if you're still on paper approvals, buried in a huge inbox mound. If you're dealing with accounting and finance app

What is Bunker Hill Security

  Bunker Hill security camera systems come with four cameras, cables, power supplies and a digital video recorder, or DVR. Because they come with simple plug-and-play cables, you won't have to worry about installing complicated BNC connectors that come with other camera systems. The cables that come with Bunker Hill security cameras are relatively short -- usually 50 to 60 feet -- so you will want to measure the distance from the camera to the DVR and purchase additional cables if needed. Step 1 Choose the location for your DVR. If you will be routing the cables through the wall, keep in mind exterior walls are difficult to route cables through because most such walls have fire breaks installed inside them about midway up the wall. Cables cannot easily be run through fire breaks so it is better to select an interior wall for the location of the DVR. Also, you should choose a wall that gives you access through the attic or access through the basement. Step 2 Choose the location for

What is the role of network engineer?

Many people will probably tell you that you need some form of degree in computer science, but that isn’t necessarily the case. Like most technical jobs there are a few qualifications and certificates you may need. One of the top qualifications you will benefit from is a CCNA, which is a Cisco Certified Network Associate certification. It will test both your theory of computer networking but also your practical knowledge in which you might be asked to do within a junior networking engineering role. As a well-respected certification in the industry not only do you look qualified but companies are aware that these tests are difficult to take. Employers For most employers they like to know the network engineer they are employing has some form of technical knowledge, giving them a level of assurance you will know what to do when you start a new role. Having well-qualified network engineers gives makes the company more reliable to work with for customers and helps to boost profitability. Pe

What is the use of 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 :   lm security

What is Network Operating

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 com
