What is Tiered Security?
Tiered security is the idea behind an assortment of defenses that cover multiple layers and that ensure that all angles and levels of attacks are taken into consideration. A tiered security system thus has a 2nd, 3rd or even a 4th layer of security in case the other levels are bypassed. Cyber attacks can come from any angle. Unfortunately, there is no one secure system that can provide all-around protection. If you are aiming for top security then a tiered security system that includes different types of utilities is your best option.
What to consider?
What are the most crucial levels and angles of protection that a tiered security system must take into consideration? In a nutshell – Real-Time Protection, Firewall, Passive Defense and Immunity, Scanning and Removal. To avoid conflicts, you can have only one real-time antivirus service and one firewall. Scanning and removal, as well as passive immunization, can have several redundant utilities so that a comprehensive protection umbrella is established. Remember also to pick respected applications that have a reliable security history.
With this little knowledge, you are now capable of building a fairly secure tiered system, at least for your personal computer.
