FAQs

One of the many valuable tools we may use to combat cybersecurity risks is the Open Systems Interconnection (OSI) concept. This long-standing standard divides a network into seven layers and provides recommendations for safeguarding each.

The most prevalent forms of application/network security are Layer 3, also known as the Network layer, and Layer 4, also known as the Transport layer. Firewalls and router Access Control Lists (ACLs) can be found in these tiers.

The transfer of bits — the 1s and 0s that make up all computer code — is handled by the Physical layer of the OSI model. This layer depicts the physical media that transports data between two nodes. Consider your Ethernet or Serial cable as an example.

The Layer of Humans:

These human management controls are designed to safeguard the information that is most important to a company's security. This encompasses the very real threat posed by individuals, cyber attacks, and malicious users to a company.

To help you remember the levels of the OSI model, below are some mnemonic phrases: "Please Do Not Throw Away Salami Pizza" – this works for both bottom-to-top and top-to-bottom. If you don't like salami pizza, then how about seafood or spinach pizza instead?
