what are the benefits of network security engineer

    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 compan

Working at layer two of the OSI model

  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 origin

what is the importance of VPN in networking

    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&quo

Cloud computing specialists

  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 and r

Why network performance is a top challenge for network

  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 protect

5 significant benefits of Using a Virtual Private Network

  A VPN is a way to connect to the internet through an encrypted connection. When you access a website, upload data to an app or check your email, the VPN encrypts all your communications and sends them to a server run by the VPN provider, which then sends them on to their destination. That is useful for preserving your privacy when you don't trust the network you're on, whether it's an internet service provider or a Wi-Fi connection at an airport or coffee shop. You can also use a VPN to connect to a corporate network for work purposes. Many companies use this method to limit access to their internal networks to employees with VPN usernames and passwords and to encrypt their connections to work machines. How Does VPN Work? A VPN encrypts all the data you send from your computer across the internet, shapes it into specially formatted packets of data and sends them to the VPN server. The server has digital keys it can use to decrypt the data, but anybody else without these k

How to reduce my upstream power level

  Upstream power levels that are too high will affect a modem connection's consistency. As the levels increase, the modem's ability to connect to the provider decreases, which may cause the modem to power down or disconnect. As with all modulation signals, the upstream power level tends to fluctuate depending on various influences including temperature and signal interference. If the problem is on your end, it may be due to poor cabling, bad connections or a faulty splitter. Troubleshoot your upstream power levels by first capturing the initial results and then begin going through the procedures necessary to identify the problem. Step 1 Connect your computer directly to the modem, using an Ethernet cable. Open a Web browser and type your router's IP address in the address bar, such as "192.168.0.1." This accesses the modem's software interface. Step 2 Click the "Status," "Signal" or "Statistics" link. The names can vary by manufac

How can I prevent the OS from storing LAN Manager

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 securit
