1:Ransomware is a hot tech topic nowadays, with those doing so targeting large and small companies alike. We can imagine that losing files in one computer is devastating, but losing all the files in a workstation can cause serious downtime for organizations.
What are some ways to prevent ransomware from becoming a serious threat?

So yes password changes are the worst. So what I have noticed is that I start a new job and we get access to all these systems at the same time, and the password will eventually change at the same time. So it seems to be on a 90 day time period, but every 90 days I'm forced to change my password, and yes at least 8 characters, capital letter, number, and symbol. Which oh my goodness is a lot. I then usually change all passwords to the next new password but they all are the same at one point.
3:I think hackers or intrusions to systems are a great risk. Hacker who infiltrate the system have access o personal or confidential information. Hackers can gain entrance a number of way. In todays society their are groups that make it a point to steal or get others information. Once they have gotten to one terminal its easier to spread and infect others.
4:Hackers can be an enormous security risk to any WAN. There are different types of hackers with different intent. Some of them just want to simply try and gain access to the network for fun to see if they can. There are others that want to cause damage to the network and have real intentions of creating problems. Then there are the hackers that are trying to gain access to steal information. We hear more about this lately in the news with the data breaches and stealing of peoples personal information and credit card numbers. This type of hacking causes serious issues to general public and the business that are being breached. Prevention for these types intrusions can try to be prevented by making sure there is a very secure firewall set in place. There should also be a proxy serer running to mask the internal IP addresses. Going even further, within the network, users should be required to have complex passwords and user names.

A key is basically a shared secret. In public key encryption, two different keys are used to encrypt and decrypt information. The private key is a key that is known only to its owner, while the public key can be made known and available to other entities on the network. The two keys are different but complementary in their purpose. For example, a user's public key can be published within a certificate in a folder so that it is accessible to other people in the organization. The sender of a message can retrieve the user's certificate from Active Directory Domain Services, obtain the public key from the certificate, and then encrypt the message by using the recipient's public key. Information that is encrypted with the public key can be decrypted only by using the corresponding private key of the set, which remains with its owner, the recipient of the message.
