Packet Analysis - Course Technology Computing Conference
Presenter: Lisa Bock - Pennsylvania College of Technology
Most network administrators are well-versed in hardware, applications, operating systems, and network analysis tools. However, many are not trained in analyzing network traffic. Network administrators should be able to identify normal network traffic in order to determine unusual or suspicious activity. Network packet analysis is important in order to troubleshoot congestion issues, create firewall and intrusion detection system rules, and perform incident and threat detection. This hands-on presentation will review fundamental concepts necessary to analyze network traffic, beginning with an overview of network analysis, then a review the TCP/IP protocol suite and LAN operations. Participants will examine packet captures and understand the field values of the protocols and as to what is considered normal behavior, and then examine captures that show exploits, network reconnaissance, and signatures of common network attacks. The program will use Wireshark, a network protocol analyzer for Unix and Windows, to study network packets, look at basic features such as display and capture filters, and examine common protocols such as TCP, HTTP, DNS, and FTP. Time permitting, the presentation will provide suggestions on how to troubleshoot performance problems, conduct a network baseline, and how to follow a TCP or UDP stream and see HTTP artifacts. Participants should have a basic knowledge of computer networking and an interest in the subject.

Hands on labs will cover the basics of asset discovery, vulnerability enumeration, system penetration, privilege escalation, and bypassing end point protection. During the labs, common vulnerabilities will be leveraged to illustrate attack techniques, using freely available tools such as Nmap and Metasploit. This training will be valuable to anyone interested in gaining a better understanding of penetration testing or to system administrators trying to understand common attack approaches.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Neuro-symbolic is not enough, we need neuro-*semantic*
Network Scanning Phases and Supporting Tools
1. Network Scanning Phases and Supporting Tools
Joseph Bugeja
Information Security Manager/Architect
November 24, 2013
2. Scanning Phase Goals
• Overall: Learn more about targets and find
openings by interacting with the target environment
–
Determine network addresses of live hosts,
firewalls, routers, etc. in the network
–
Determine network topology of target environment
–
Determine operating system types of discovered
hosts
–
Determine open ports and network sevices in target
environment
–
Determine list of potential vulnerabilities
–
Do these in a manner that minimizes risk of
impairing host or service
3. Scan Types
• Network Sweeping
–
Send a series of probe packets to identify live hosts
at IP addresses in the target network
• Network Tracing
–
Determine network topology and draw a map
• Port Scanning
–
Determine listening TCP and UDP ports on target
systems
• OS Fingerprinting
–
Determine the target operating system type based
on network behaviour
4. Scan Types
• Version Scanning
–
Determine the version of services and protocols
spoken by open TCP and UDP ports
• Vulnerability Scanning
–
Determine a list of potential vulnerabilities
(misconfigurations, unpatched services, etc.) in the
target environment
5. Scanning Tip: While Scanning Run a
Sniffer
• Whenever you run a scan, run a sniffer so that you
can monitor network activity
–
You do not have to capture all packets in the file
system
•
–
That would likely require huge storage space
Instead, display them on the screen so you can
visualize what is happening in the scan
• Which sniffer to use?
–
–
Any sniffer that shows packet headers will do, but
you want something small, flexible and fast
tcpdump is ideal for this purpose
6. Scanning Tip: Use TCPDump
• Free, open source sniffer
–
–
www.tcpdump.org
Ported to Windows as WinDump at
www.winpcap.org/windump/default.htm
• Supports various filtering rules
• While testing, you will likely have it display all
packets leaving from and coming to your scanning
machine
• But, for specific issues, you may need to focus on
specific packets
• Often, just running tcpdump with no special options
while scanning provides the information you need
$ sudo tcpdump
7. Network Sweep Tools
• Angry IP
–
–
www.angryip.org
GUI-based tool for Windows
•
•
•
•
Ping sweep (via ICMP Echo Request)
TCP port scan
Gets MAC address for systems on same subnet
NetBIOS name and workgroup gathering
• ICMPQuery
–
–
www.angio.net/security/icmpquery.c
Command-line tool for Linux/UNIX
•
•
Sends ICMP Timestamp (Type 13) and Address
Mask Request (Type 17) messages to identify
live hosts
Useful for identifying hosts in a network that has
firewalls which block ICMP Echo Request
8. Network Sweep Tools
• HPing
–
Inspired by ping, but goes much further
•
•
–
–
–
Free at www.hping.org, runs on Linux, *BSD,
Windows and MacOS X
The latest version, Hping3, supports TCL scripting
By default, sends TCP packets with no control bits
set to target port 0 continuously, once per second
•
–
Originally Hping, then Hping2...latest is Hping3
From man page: “Send (almost) arbirary TCP/IP
packets to networks hosts”
Possibly getting RESETs back
Example: # hping3 10.10.10.20
9. Network Tracing Tools
• Traceroute
–
–
–
–
Discovers the route that packets take between two
systems
Helps a tester construct network architecture
diagrams
Included in most operating systems
Sends packets to target with varying TTLs in the IP
Header
• Layer Four Traceroute (LFT)
–
Free at http://pwhois.org/lft
–
Runs on Linux and Unix
–
Supports a variety of Layer Four options for
tracerouting
10. Network Tracing Tools
• 3D Traceroute
–
–
Runs on Widows, free at www.d3tr.de
Graphical traceroute using ICMP Echo Request,
updated/animated in real-time
• Web-Based Traceroute Services
–
Instead of tracerouting from your address to the
target, various websites allow you to traceroute
from them to the target
–
Very useful in seeing if you are being shunned
during a test!
11. Port Scanning Tools
• Nmap
–
Written and maintained by Fyodor
•
–
–
Very popular, located at www.insecure.org
Has been extended into a general-purpose
vulnerability
scanner
via
Nmap
Scripting
Engine(NSE)
Run with --packet-trace to display summary of each
packet before it is sent, with output that includes:
•
•
•
•
•
•
•
Nmap calls to the OS
SENT/RCVD
Protocol (TCP/UDP)
Source IP:Port and Dest IP:Port
Control Bits
TTL
Other header information
12. OS Fingerprinting Tools
• Nmap
–
–
Attempts to determine the operating system of
target by sending various packet types and
measures the response
Different systems have different protocol behaviour
that we can trigger and measure remotely
• Xprobe2
–
ofirarkin.wordpress.com/xprobe
–
Based on Ofir Arkin ICMP fingerprinting research
–
Applies fuzzy logic to calculate the probabilities of
its operating system type
• P0f2
–
–
Supports passive OS fingerprinting
Free
13. Version Scanning Tools
• Nmap
–
Version scan invoked with -sV
- Or use -A to for OS fingerprinting and version
scan (i.e, -A = -sV + -O)
• THC Amap
–
Free from http://freeworld.thc.org/thc-amap
–
Amap can do a port scan itself or it can be provided
with the output file from Nmap
–
It sends triggers to each open port
–
It looks for defined responses
–
A useful second opinion to the Nmap version scan
14. Vulnerability Scanning Tools
• Nmap Scripting Engine (NSE)
–
–
Scripts are written in the Lua programming
language
May some day rival Nessus and NASL as a general
purpose, free, open source vulnerability scanner
• Nessus Vulnerability Scanner
–
Maintained and distributed by Tenable Network
Security
