What is security engineer

  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 :...

Dumping Domain Password Hashes

  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 :  cyber security engineer j...

What is CCM Cache

  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...

cloud services and software-as-a-service

  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 lm security in networking?

  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 security engineer jobs

What is Birth of Networks

  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 ...
