Week 9 – Summary

Readings:

Wireshark was developed in 2006 (originally called Ethereal as was developed by Gerald Combs back in 1998) and so far is the best free Open Source tool that is used for deep network data packet analysis, in which comprehensive information is extracted from captured network transmissions. Wireshark provides analysis of all 7 layers of the OSI model, which helps to troubleshoot network communications issues, discover security flaws, debug and learn network protocols. Wireshark is compatible with various OS flavors and customizable for development purposes.

Question to the Class: Would BurpSuite be a good fit as competitor for packet analysis of Layer 7 of OSI model?

In the News: Subgraph OS — Secure Linux Operating System for Non-Technical Users

Subgraph OS was designed from the ground-up to reduce the risks in endpoint systems so that individuals and organizations around the world can communicate, share, and collaborate without fear of surveillance or interference by sophisticated adversaries through network borne attacks.

Subgraph OS is designed to be difficult to attack. This is accomplished through system hardening and a proactive, ongoing focus on security and attack resistance. Subgraph OS also places emphasis on the integrity of installable software packages.

Special Features:

• Oz is a system for isolating programs so that if an attacker exploits an application security vulnerability, the rest of your machine and your network will remain largely unaffected.

• Mandatory Full Disk Encryption (FDE)

• Online Anonymity — Everything through Tor

• Advanced Proxy Setting

• System and Kernel Security

• Secure Mail Services

• Package Integrity
