Cybersecurity Overview
Info
Cybersecurity is the protection of computer systems, networks, and information systems from theft, damage, disruption, misdirection, and unauthorized alteration.
The components of the Bitstream cybersecurity implementation may be divided into two categories - core measures and advanced measures. Core cybersecurity measures are intrinsic to each subsystem of the IT infrastructure and always exist and are included in the base monthly price. Advanced add-on cybersecurity measures are recommended but optional additional layers of defense.
Cybersecurity measures can be divided into three categories based on where they are located - cloud, perimeter, and endpoint. As the name suggests, cloud defenses operate in the cloud. Perimeter measures are located on the edge of the client network, at the firewall between the client network and the Internet. And endpoint measures are located on each computer or server.
| Defense Measure | Classification | Location | Provides For |
|---|---|---|---|
| Principle Of Least Privilege | Core | All | Default secure settings, default deny permissions across all computers, servers, network equipment, and information systems |
| Quad9 DNS Filtering | Core | Cloud | DNS filtering of known malicious Internet sites |
| Cisco Meraki Security Appliance | Core | Perimeter | Edge firewall with Content Filtering, IDS/IPS, Advanced Malware Protection (AMP) |
| Endpoint Protection | Advanced | Endpoint | Antivirus / Anti-Malware / Anti-Ransomware Endpoint Protection |
| Managed Secure Drive | Advanced | Endpoint | Managed drive encryption at both the block layer (BitLocker) and file system layer (EFS) |
| Managed Secure Messaging | Advanced | Cloud | Secure, encrypted transmission of sensitive data |
| Managed Password Vault | Advanced | Cloud | Secure storage and access of security credentials, identities, and secrets |
| Managed Continuous Compliance | Advanced | Endpoint | NIST Standard based Continous Security and Vulnerability Manager |
| Phishing Training And Testing | Advanced | Cloud | User training and testing to reduce the risk of a cybersecurity breach |
| Cloud Backups | Advanced | Cloud | Continuous backups of important files to the cloud over an encrypted tunnel |
Info
Bitstream uses all of the above to create a multilayered defense in depth 1 cybersecurity strategy.
