The Information security triad consists of 3 areas (obviously). These areas are crucial to have a functional security system that is implemented in a work system. The first one is Confidentiality, referring to how an organization keeps their data and information secret and secured. The second part is Integrity, referring to the quality of the security, making sure that the important info gets prioritized and protected in the event of a cyber threat. The third and final part is Availability, which refers to ensuring that the information and data can be accessed whenever as long as someone has the proper clearance and credentials. The tools that can be used to ensure that the security triad is put into good use are as follows: 1. Authentication, 2. Access Control, 3. Password Security, and 3. Encryption. Authentication refers to these three factors:

1. Something they know
2. Something they have
3. Something they are

The most commonly used authentication method is UserID and Passwords. This brings in Password Security and how users need to be able to make the safest password possible, while also ensuring that they don’t make it too complicated to where they could possibly forget it. Yet, this common form of authentication is easy to compromise. This is where a physical form of authentication comes in like fingerprint scanners, retinal scans and Facial ID. These are known as Biometrics. Access Control is the step that comes after a user has been authenticated. Access control determines which users are authorized to read, modify, add, and/or delete information. Encryption is when an organization needs to transfer or send information to another system or person. So when sending it, they encrypt it and give the key to someone on the other end so that they can access it. All they need is one private key and one public key. The private key is necessary in order to decrypt a message sent with the public key.

Now, to the use of firewalls. Firewalls are a piece of software that can run on a computer, a router, or a stand-alone appliance. They prevent unwanted packets from getting access to your network. Personal firewalls ensure that your devices and software doesn’t get affected by filtering out the unwanted packets. Some firewalls even rate the risk of any unwanted packets and filter them through a high-value threat to a low-level threat.

The risks of cyber security on a national scale don’t really differ between countries. The most common threat in the U.S. can range from social hacking and ransomware, to the highest threat of a DDoS attack. A DDoS attack is one of the higher tier threats that, no matter the country, faces. It distributes some many packets to a network all at once that it causes a system to shut down and prevent further damage. While this sounds minor, it does open up a network to having information and data taken.
