Finding Careers In Technology

  1.Poor network performance. There’s no question that poor network performance is a top challenge for network engineers. There isn’t simply more total traffic; there’s more traffic in all directions. Without the right equipment at endpoints and midpoints along the way, it’s impossible to provide the high-speed communication needed by today’s applications. Plus, performance isn’t just about speed; it’s about reliability, too. Network designs need to handle spikes in load and provide alternate routes to enable communication to continue even when a link fails. 24×7 online business requires 24×7 network availability. 2.Security. Security is another top challenge. Because the perimeter of today’s network is unclear, blocking unauthorized outside traffic from the internal network isn’t adequate for protecting data. Many threats make it into the network when employees respond to a phishing email. Denial of service attacks only need to attempt connections to succeed. Encryption helps prot...

  The Open Systems Interconnect (OSI) model for network communications establishes a layered approach to communicating between computers on a network. Each layer of this seven-layer model may have its own way of referring to the other computers with which it communicates. This means that any given network server may have many different addresses on file--for use with the different communications layers at work. Ethernet Working at layer two of the OSI model, all systems connected to an ethernet network will have a unique ethernet address. This address is expressed as a set of eight hexadecimal values, such as 00-2B-78-5F-03-8A. This address may be used by network switches and bridges to help constrain and route traffic to this particular server. Internet Protocol The Internet Protocol, working at layer three of the OSI model, establishes a unique IP address for every machine on the Internet. IP addresses have three parts: network address, node address and subnet mask. Though the or...

  You want to prevent the LM hash for new passwords from being stored in Active Directory. The LM hash is susceptible to brute force attacks and is primarily used for backward compatibility with Windows 95 and 98 clients. Solution For Windows 2000, you need to create the following Registry key on all domain controllers: HKLM\SYSTEM\CurrentControlSet\Control\Lsa\NoLMHash. Note that this is a key and not a value entry. Also, this is only supported on W2K SP2 and later domain controllers. For Windows Server 2003, the NoLMHash key has turned into a DWORD value entry under the HKLM\SYSTEM\CurrentControlSet\Control\Lsa key. This value should be set to 1. You can accomplish this by modifying the Default Domain Controller Security Policy as described next. Using a graphical user interface 1.Open the Group Policy Object Editor and target the Default Domain Controller Security Policy. 2.In the left pane, expand Local Policies → Security Options. 3.In the right pane, double-click on Network s...

  Financial and trading firms don’t care about a “fair game”, all they care is winning and making a profit. Thanks to high-end technology, they have the ability to trade extremely fast which gives them advantages on the market. Low latency networks are the weapons of choice! The trading game is still the same, what has changed is the technology behind it. Supercomputers are replacing those agitated traders at the halls of the exchange office trying to pass their orders. Today is no longer  the guy who can scream and jump louder, but  the equipment that can process and send orders faster. This high demand for speed in trading and financial networks has brought a new kind of technology into the field.  Today, a financial firm with the right technology is able to process an order in less than 400 microseconds (µs or 0.0004 second), more than twice the speed of a camera’s flash. find more :  lan manager

  In Brazil, the area of Information Technology is one of the most recruited. But even with potential job openings, the market still has a shortage of good professionals. The Alcides Maya helps the student to achieve the high profile level in its segment, so its curriculum includes stages within demanding companies before forming it. But how is the job market going for good IT professionals ? The answer is: warm. The computerization of all areas of an organization requires expert contributors in data networks, Internet systems, among others. In this context, the most required professions by organizations today are: 1) Cloud computing specialists : they are professionals who work together to analyze the indicators of the computing environment and the evolution of systems infrastructure, with the objective of improving performance, availability and security. from the cloud . These specialists should set aside some of their time for updates and knowledge, as this is ongoing training a...

  Today’s networks need to support more traffic than ever. Employees access corporate data from desktops and mobile devices. Internet of Things devices proliferate everywhere on premises.

  When they ask me about a good VPN service, I don’t know what to say. The essence of all services is the same - hiding your IP and access to blocked resources. Someone does it better, and someone worse. As a result, the choice of service is reduced to the personal requirements of the questioner. I can only tell which service is worth a try. And in this article I will talk about ALTVPN. The name of the service stands for Alternative Secure Services, and in fact ALTVPN is an alternative VPN. Let's see why. On a separate page, you can get detailed instructions for installing ALTVPN on your device. I will not talk about manual configuration through PPTP or OpenVPN, everything is too individual here and requires experience. But ordinary users can download the application for their device. This setup takes literally half a minute. For example, on Windows, when starting the application, you just need to specify the user code, select the connection server and click the "Connect"...

  Network security components consist of many pieces, including: Anti-virus and anti-spyware Web protection Email security Backup and recovery Network Security Payoffs Network security has a number of benefits for defending your clients’ businesses against threats. Obviously the number one advantage is minimizing the level of risk for attacks, infections, and breaches. For most companies, reaching an acceptable level of security can be difficult, if not impossible, to achieve on their own, even for organizations that have their own IT staff and help desk. With the right network security tools, however, MSPs can offload the security yoke from organizations and protect their clients’ computer systems, networks, files, and data from attacks and breaches. Keeping files free from infection is particularly important in today’s collaborative workplace, where information is shared among co-workers inside a company as well as with partners, consultants, analysts, and others outside the comp...
