Yes, they can.
True
Network Security Consultants protect a network from outside forces such as malicious spyware. They usually work for companies to protect their assets against hackers through firewalls.
Somewhat, but a firewall is NOT a reliable source of security. It seems that firewalls are fairly easy to get around, so if you're being harassed by a hacker, find a program that will find and kick them off instead of simply blocking them. Simply put, firewalls are cheap and just won't do the job against a seasoned hacker.
You need the same hardware, firewalls, and antivirus software to protect one computer as you need to protect 25.
A firewall is the device used to protect one network from another by filtering packets. It monitors and controls incoming and outgoing network traffic based on predetermined security rules. Firewalls can be hardware-based, software-based, or a combination of both, and they help prevent unauthorized access and attacks on a network.
Yes, there is a distinction between personal firewalls and software firewalls, although the terms are often used interchangeably. A personal firewall is typically a software application designed to protect individual devices, such as PCs or laptops, from unauthorized access and threats. In contrast, a software firewall can refer to any firewall implemented in software, including those used on servers or network devices, and may not be limited to personal use. Essentially, all personal firewalls are software firewalls, but not all software firewalls are personal firewalls.
Firewalls do not protect from viruses. Firewalls can help reduce the chances of being hacked, though an expert hacker might still find a way in. But it will be harder and take more time.
An example of a technical control is the use of firewalls to protect a network from unauthorized access. Firewalls monitor and filter incoming and outgoing network traffic based on predetermined security rules, helping to prevent cyber threats. Other examples include encryption of data in transit and at rest, as well as intrusion detection systems that identify and respond to potential security breaches.
Firewalls protect one computer (or network) from another computer (or network) by imposing limits on how those two computers (or networks) can interact. In one example, you might have several computers in your internal network. You can control them by using telnet. You could use a firewall between your internal network and an external network to prevent a computer in the external network from accessing a computer in the internal network using telnet. Since telnet can be a security risk, blocking external telnet like this is highly appropriate. In another example, you might have a private firewall on your computer. You use the computer to browse other computers using http. You firewall could be configured to ensure that only the processes iexplore.exe or firefox.exe were allowed to use http. This way, if some malicious program, for instance malware.exe, attempted to use http, it would be blocked. Blocking can also be applied to external sites by address. There are many possibilities... Most modern firewalls are extremely complex, because there are many different possible interactions. Some are good, and some are bad.
it the virtual privet network that can protect you data when you use it on your iPhone you can download an app for it it's called VPN Express its can help you protect your data or get into blocked firewalls . share by Mohamed <----- best name ever
Once thought of as a perimeter defense security layer, firewalls are being brought into the infrastructure to protect different segments of the network such as finance, HR and engineering. Using firewalls as part of the internal network security solution will provide additional layers of access control to protect against the organization's sprawling definition of "authorized user," as well as provide attack containment. Adding firewalls to the infrastructure enables enterprises to protect specific resources, forcing users to authenticate themselves as they move from network to network, thereby reducing the risk of unauthorized access to sensitive information. In addition to user containment, internal firewalls add attack containment to the network to prevent damages from spreading in the event that an attack occurs. Examples of effective use of network segmentation include wireless LANs and customer extranets. Placing these users in their own segment, behind their own policy-based firewall, will allow enterprises to contain the users as well as any potential damages that may occur if an attack were to succeed. Rather than buying a separate, physical firewall for every segment, Juniper Networks provides the ability to segment the network through the high physical and virtual port densities of our products.
