Unlocking Cyber Security: Seven Layers of Protection


Cyber security is a critical concern for businesses and individuals alike. Here's an inside look at the seven layers of cyber security that I've been working on to ensure the utmost protection:

Step 1: Critical Mission Assets

Description: This involves identifying and protecting the essential assets required for the mission. These could include hardware, software or data, each playing a crucial role in the overall security.

Step 2: Data Security

Description: At this stage, measures are taken to safeguard data, both at rest and in transit. This includes encrypting sensitive information and establishing secure communication channels.

Step 3: Application Security

Description: This step focuses on securing applications from threats. This is done by adopting secure coding practices, conducting regular audits and implementing stringent access controls.

Step 4: Endpoint Security

Description: This involves securing all endpoints in the network to prevent unauthorized access, thereby reducing the potential risk of data breaches.

Step 5: Network Security

Description: At this level, we concentrate on protecting the network infrastructure with controls like firewalls and intrusion detection systems.

Step 6: Perimeter Security

Description: This involves setting up defenses around the network to keep out potential attackers. This includes regular vulnerability assessments and patch management to fix any identified weaknesses.

Step 7: Human Layer

Description: This final step focuses on training and awareness programs for staff. After all, the best security systems in the world can be rendered useless if humans inadvertently provide access to cybercriminals.


Working on this project has highlighted the fundamental role each layer plays in maintaining robust cyber security.
