MAC OS FIREWALL USE OR NOT WINDOWS

Does the firewall protect against hackers?ДЇor a long-time UNIX people used to ridicule Windows as an unsafe operating system, but the truth is that UNIX/Linux servers been hacked more often than Windows.

They protect from different security threats. Firewalls and antivirus applications do not replace or substitute each other.

But generally, this is rarely a case.ДЇirewalls do not check for viruses when one downloads software from the internet. If the malware algorithm is such as it needs to accept incoming connections from external programs, then having a firewall may break the malware. In the worst case, they simply destroy your software and documents. Or they can change your browser to redirect to some sites and make money this way. They can collect information such as credit cards and login credentials and transfer it to interested parties. They can encrypt the local disk and then request to pay in bitcoins for decryption. They can infect other programs with bad code. There are many ways the malware can harm your computer. No, antivirus software designed to verify that the software that gets downloaded or runs on your computer does not have malicious code. If the IT department didnвЂ™t catch my mistake fast enough, then hackers could use the scanning software, steal important information and IвЂ™d be fired. Now, the firewall would allow connecting to the servers only if the request was coming from my IP address, i.e., my Mac. With its help, they were able to find holes on my servers which hackers could employ to steal the data.Д®ventually, I restored those VMs, turned on the firewall, and cut all connections to the world. The IT department used a scanning software which checks all servers for vulnerabilities. Next day, IвЂ™ve got an angry email from the IT department, and they shut down my VMs completely. I didnвЂ™t know however that the software I ran on those VMs did not enforce authentication and the data was wide open for anyone on the internet.

AWS offers firewall services, but to make my life easier, I turned them off for my VMs. I installed some services that I could connect from my MacBook. When I just started working with Amazon AWS, I set up a couple of virtual machines (VMs) in the cloud. With outgoing connections the process is reversed: local applications get prevented from sending requests outside. When a firewall restricts or blocks incoming connections, it disallows applications running on your computer, accept requests from other computers. There are different things that firewalls can do, but generally, they designed to restrict incoming or outgoing network connections. There are two types of firewalls: hardware and software. However, it is recommended to have the firewall turned on for MacBooks to protect from hacker attacks when connecting to public networks. The home Wi-Fi router serves as a firewall in this case, and adding another one will not add more protection.

So, do you need a firewall on your Mac? There is no need to have a firewall on desktop Apple computers such as iMac or Mac mini. I decided to put everything I know together and hopefully answer all the questions you might have. The truth, as usual, is somewhere in the middle. Some experts claim that the firewall is not necessary, but some scare us with grave consequences. There is so much confusion around the topic of Mac firewalls.
