Prototype Open-Source Software Stack for the Reduction of False
CYBER 2018 : The Third International Conference on Cyber-Technologies and Cyber-Systems Prototype Open-Source Software Stack for the Reduction of False Positives and Negatives in the Detection of Cyber Indicators of Compromise and Attack Hybridized Log Analysis Correlation Engine and Container-Orchestration System Supplemented by Ensemble Method Voting Algorithms for Enhanced Event Correlation Steve Chan Decision Engineering Analysis Laboratory San Diego, California U.S.A. email: [email protected] Abstract—A prototypical solution stack (Solution Stack #1) black boxed commercial offering itself. Accordingly, with chosen Open-Source Software (OSS) components for an MSSPs are endeavoring to put forth their own offerings experiment was enhanced by hybridized OSS amalgams (e.g., (also for market differentiation), in a white box fashion; for Suricata and Sagan; Kubernetes, Nomad, Cloudify and Helios; the purposes of adhering to Joyce’s recommendation, the MineMeld and Hector) and supplemented by select modified white box approach can be, in some cases, more effective algorithms (e.g., modified N-Input Voting Algorithm [NIVA] modules and a modified Fault Tolerant Averaging Algorithm than the black box approach, but it is a much more difficult [FTAA] module) leveraged by ensemble method machine pathway in terms of the sophistication needed to understand learning. The preliminary results of the prototype solution and appropriately orchestrate the various involved stack (Stack #2) indicate a reduction, with regards to cyber subsystems. By way of example, a Verizon Data Breach Indicators of Compromise (IOC) and indicators of attack Report had articulated that those with robust log analysis (IOA), of false positives by approximately 15% and false and correlation were least likely to be a cyber victim; yet, negatives by approximately 47%. -
Logging and Monitoring at Home Who Am I
Defending the Homeland Logging and Monitoring at home Who am I @nullthreat Offensive Red Team for a major company I break stuff Started security @ CNDSP ADT for networks @ DOD Designed and Deployed NSM on DOD net Talking Points Perimeter Firewall Central Logging Host IDS Network IDS Basic Honeypots Deployment Strategies Disclaimer: The ideas and solutions presented are my opinion, feel free to disagree. OS'es I use all Linux and Macs at home I will not be talking about Windows at all, deal with it Won't matter once we are talking NIDS Firewalls on the Cheap As I see it there is only one good solution in this space PFSense http://www.pfsense.org ● Fork of MonoWall ● Robust Firewall based on PF(FreeBSD) ● Multiple VPN Support built-in ○ OpenVPN, IPSec, L2TP, PPTP ● Package based add-ons ○ pfBlocker(block netblocks), Snort, Squid ● Runs on almost anything, Full PC or Embedded Embedded Solutions ALIX 2D3/2D13 ~ 200$ @ store.netgate.com PFsense on Alix Setup Pauldotcom.com tech segement from episode 220 Google "alix pfsense pauldotcom" and you'll find the show notes Spark notes: Download IMG, Write to CF Card, Boot, Use Serial Terminal to do initial setup PFSense on Alix Setup Pro Tip: Don't put the box together until you flash the OS onto the card, You have to take the entire box apart to get the CF Card in and out. PFSense Demo Other Options Surplus Cisco/Juniper/Checkpoint Hardware Consumer Firewall Solutions http://en.wikipedia. org/wiki/List_of_router_or_firewall_distributions Firewalls Questions? Central Logging I do this on my servers and VPSs Could do on clients but....meh Usually the same box that hosts my NIDS stuff Lots of options syslogd Ol' reliable Been around since the dawn of freaking time originally part of sendmail circa 1980s UDP Only(in most cases) Easy-ish to configure but hard to really dial in syslogd Server: set -r flag in /etc/sysconfig/syslog ex. -
