Traditional security systems primarily focus on three types of mechanisms: backend network security (VLANs, secure networks, etc.), perimeter defense (intrusion detection, firewalls, etc.), and security permission management (access control lists, business rules, etc.). The hope is that outside attacks are prevented by keeping the Perimeter secured.The problem is that the perimeter defenses can be defeated or avoided altogether by an inside attack. Once an admin account is compromised, the perimeter defense and permission management offer no protection; there is little stopping the attackers from accessing all the information within the Perimeter. This reaffirms that traditional data security models, including perimeter defense, are fundamentally flawed. Each occurring breach, compromised server, or hijacked admin account mounts evidence against the traditional model.The one thing the hackers (and arguably even governments) are not capable of breaching is strong encryption. If the data on the server is encrypted at all times with keys controlled by individual users, a data breach would reveal very little to an attacker. For this reason, the primary defense mechanism at Tera Insights is the reliance on user-controlled end- to-end encryption, not server security. When coupled with traditional defense mechanisms, tiCrypt offers a much more secure solution to data storage, sharing, and processing. In effect, an attacker has to defeat both the encryption-based and the perimeter-based defences to steal data–a much more challenging task for one to be successful at.
