Database firewall is a useful tool that monitor databases to identify and protect against database specific attacks that mostly seek to access sensitive information stored in the databases. However the commercial database firewalls are expensive and needs specific product knowledge, while the opensource database firewalls are designed for specific opensource database servers.
In order to fulfill the need of inexpensive database firewall, Snort - an opensource IDS/IPS - is possible to achieve the goal in some scenarios with familiar rule writing. The paper will explain the limitation of Snort as a database firewall, constraints in commercial database statement and some example implementation.

The detail architecture of the most relevant consumer drones will be introduced, continuing with the communications protocol between the pilot (app in the smartphone or remote controller) and the drone. Manual reverse engineering on the binary protocol used for this communication will lead to identifying and understanding all the commands from each of the drones, and later inject commands back.
Learning Objectives:
1: Understand whenever a protocol between drone and pilot is secure.
2: Learn about a new reverse engineering methodology for these protocols.
3: Review a set of good practices to secure the environment surrounding a drone.

The goal of this report is to focus on one particular aspect of malware: the Command & Control (aka C&C or C2C) infrastructure; in other words, the set of servers and other kind technical infrastructure used to control malware in general and, in particular, botnets. For this purpose, two malicious samples have been analyzed in this work, by means of state-of-the-art static and dynamic analysis tools, also described at high level in this report; the achieved goal was to understand their networking behaviour and to derive the techniques used by those to hide their malicious traffic to unaware users, with the goal of staying as long as possible in the system and keeping their malicious business going.
Sniffing is the process of monitoring and capturing all the packets passing through a given network using sniffing tools. It is a form of “tapping phone wires” and get to know about the conversation. It is also called wiretapping applied to the computer networks.
There is so much possibility that if a set of enterprise switch ports is open, then one of their employees can sniff the whole traffic of the network. Anyone in the same physical location can plug into the network using Ethernet cable or connect wirelessly to that network and sniff the total traffic.
In other words, Sniffing allows you to see all sorts of traffic, both protected and unprotected. In the right conditions and with the right protocols in place, an attacking party may be able to gather information that can be used for further attacks or to cause other issues for the network or system owner.
Ending the Tyranny of Expensive Security ToolsSolarWinds
A long time ago, in a galaxy far far away, AV was invented. Then firewalls and IDS and SIEM and NAC and DLP and on and on. With all these products, it seems like a career in information security is really more about managing tools than defeating a galactic empire of hackers and miscreants. But like the Rebel Alliance, you can take back your enterprise, because many of our existing monitoring systems and network devices also have security functionality. Moreover, there are many excellent open source applications that work just as well as commercial ones.
You don't always have to buy something expensive to provide security functionality. After all, a security professionals job isn't to manage tools, but solve problems. This presentation talks about how to use open source and existing monitoring tools to meet an organization's security needs.
To secure a network, someone in the organization must know exactly where the network needs to be secured. Although this step may sound simple and obvious, many companies skip it. They install a perimeter firewall and then relax, lulled into a sense of security by this single layer of defense. To truly assess the risks within a computing environment, you must deploy technical controls using a strategy of defense in depth, which is likely to include IDPSs, active vulnerability scanners, passive vulnerability scanners, automated log analyzers, and protocol analyzers (commonly referred to as sniffers).
Everything you really need to know about IDS (Intrusion Detection Systems) Combining with HoneyPots. Deployment and usage techniques used in the past and today. How to setup and deploy onto any network including the cloud. Reasons why this should be used in all networks. How to bring BIG DATA down to Small Data that is easy to understand and monitor.
It’s all over the news that data breaches occur daily! I asked WHY these hackers can download terabytes of data in timespans of months without being noticed. What are these companies paying their SOC team millions of dollars for? How come all the money is going to devices to prevent breaches and little to none in detecting when they occur? Don’t people know there are only two types of companies “those that been hacked, and those that don’t know they been hacked”. What can I do to detect a breach within seconds on any network scale? I think I figured it out. In my talk you’ll learn how you and your clients can benefit by applying my exclusive techniques, which I’ve successfully deployed. So the next time you get hacked the hacker would not be able to steal all those credit cards and photos of that Halloween party.
The project entitled with “Network Security System” is related to hacking attacks in computer systems over internet. In today’s world many of the computer systems and servers are not secure because of increasing the hacking attacks or hackers with growing information, so information security specialist’s requirement has gone high.
1. SECURITY TOOLS
Vulnerability assessment tools:
Nessus:
http://www.nessus.org/
The premier Open Source vulnerability assessment toolNessus is a remote security scanner
forWindows, Linux, BSD, Solaris, and other Unices. It is plug-in-based, has a GTK interface,and
performs over 1200 remote security checks. It allows for reports to be generated in HTML, XML,
LaTeX, and ASC II text, andsuggests solutions for security problems.
Hping2 :
http://www.hping.org/
A network probing utility like ping on steroids hping3 assembles and sends custom ICP/UDP/TCP
packets and displays anyreplies. It was inspired by the ping command, but offers far more
control over the probes sent. It also has a handy traceroutemode and supports IPfragmentation.
This tool is particularly useful when trying to traceroute/ping/probe hosts behind a firewallthat
blocks attempts using the standard utilities.
DSniff :
http://naughty.monkey.org/~dugsong/dsniff/
A suite of powerful network auditing and penetration-testing tools.This popular and well-engineered
suite by Dug Song includes many tools. dsniff, filesnarf, mailsnarf, msgsnarf, urlsnarf, andwebspy
passively monitor a network for interesting data passwords, e-mail, files, etc. arpspoof, dnsspoof,
and macof facilitatethe interception of network traffic normally unavailable to an attacker e.g,
due to layer-2 switching . sshmitm andwebmitmimplement active monkey-in-the-middle attacks
against redirected SSH and HTTPS sessions by exploiting weak bindings in ad-hocPKI. A separately
maintained partial Windows port is available here.
GF I LANguard :
http://www.gfi.com/lannetscan/
A commercial network security scanner for WindowsLANguard scans networks and reports
information such as service pack level of each machine, missing security patches, openshares,
open ports, services/applications active on the computer, key registry entries, weak passwords,
users and groups, andmore. Scan results are outputted to an HTML report, which can be
customised/queried. Apparently a limited free version isavailable for non-commercial/trial use.
Sam Spade:
2. http://www.samspade.org/ssw/
SamSpade provides a consistent GUI and implementation for many handy network query tasks. It
was designed with trackingdown spammers in mind, but can be useful for many other network
exploration, administration, and security tasks. It includes tools such as ping, nslookup, whois, dig,
traceroute, finger, raw HTTP web browser, DNS zone transfer, SMTP relay check, websitesearch, and
more. Non-Windows users can enjoy online versions of many of their tools.
ISS Internet Scanner: Application- level vulnerability assessment :
http://www.iss.net/products_services/enterprise
_protection/vulnerability_assessment/scanner_internet.php
Internet Scanner started off in '92 as a tiny Open Source scanner by Christopher Klaus. Now he has
grown ISS into a billion-dollar company with a myriad of security products. ISS Internet Scanner is
pretty good, but is not cheap. So companies on a tight budget may wish to look at Nessus instead.
A March 2003 Information Security magazine review of 5 VA tools including these isavailable
here. Note that VA tools only report vulnerabilities. Commercial tools for actually exploiting them
include CORE Impactand Dave Aitel's C anvas. Free exploits for some vulnerabilities can be found at
sites like Packet Storm and SecurityFocus
Nikto:
http://www.cirt.net/code/nikto.shtml
Nikto is a web server scanner which looks for over 2600 potentially dangerous files/C GIs and
problems on over 625 servers. Ituses LibWhisker but is generally updated more frequently than
Whisker itself.
SuperScan: F oundstone's Windows TCP port scanner :
http://www.foundstone.com/index.htm?subnav=resources/navigation.htm
A connect-based TC P port scanner, pingerand hostname resolver. No source code is provided. It can
handle ping scans and portscans using specified IP ranges. It can also connect to any discovered open
port using user-specified
SAINT :
http://www.saintcorporation.com/saint/
Security Administrator's Integrated Network Tool, Saint is another commercial vulnerability
assessment tool like ISS Internet Scanner or eEye Retina . Unlike those Windows-onlytools, SAINT
runs exclusively on UNIX. Saint used to be free and open source, but is now a commercial product.
SARA: Security Auditor's Research Assistant :
3. http://www-arc.com/sara/
SARA is a vulnerability assessment tool that was derived from the infamous SATAN scanner. They
try to release updates twice amonth and try to leverage other software created by the open source
community such as Nmap and Samba .
N- Stealth: Web server scanner:
http://www.nstalker.com/nstealth/
N-Stealthis a commercial web server security scanner. It is generally updated more frequently
than free web scanners such aswhisker and nikto, but do take their web site with a grain of salt. The
claims of
Firewalk: Advancedtraceroute :
http://www.packetfactory.net/projects/firewalk/
Firewalk employs traceroute-like techniques to analyze IP packet responses to determine gateway
AC L filters and map networks.This classic tool was rewritten from scratch in October 2002. Note
that much or all of this functionality can also be performed bythe Hping2 --traceroute option.
XProbe2: Activ e OS fingerprinting tool :
http://www.sys-security.com/html/projects/X.html
XProbeis a tool for determining the operating system of a remote host. They do this using some of
the same techniques as Nmapas well as many different ideas. Xprobe has always emphasized the IC MP
protocol in their fingerprinting approach.
Toolsets: A plethor of network discovery /monitoring/ attack tools :
http://www.solarwinds.net/
SolarWinds has created and sells dozens of special-purpose tools targetted at systems
administrators. Security related toolsinclude many network discovery scanners and an SNMP
brute-force cracker. These tools are Windows only, cost money, and donot include source code.
THC- Amap: An application fingerprinting scanner :
http://www.thc.org/releases.php
Amap by THC is a new but powerful scanner which probes each port to identify applications
and services rather than relying onstatic port mapping.
Hunt: An advanced packet sniffing and connection intrusion tool for Linux:
http://lin.fsid.cvut.cz/~kra/index.html#HUNT
4. Hunt can watch TC P connections, intrude into them, or reset them. Hunt is meant to be used
on ethernet, and has activemechanisms to sniff switched connections. Advanced features include
selective ARP relaying and connection synchronization afterattacks. If you like Hunt, also take a look at
Ettercap and Dsniff.
A Windows web attack proxy :
http://achilles.mavensecurity.com/
Achilles is a tool designed for testing the security of web applications. Achilles is a proxy server, which
acts as a man-in-the-middleduring an HTTP session. A typical HTTP proxy will relay packets to and
from a client browser and a web server. Achilles willintercept an HTTP session's data in either
direction and give the user the ability to alter the data before transmission. For example,during a
normal HTTP SSL connection a typical proxy will relay the session between the server and the
client and allow the twoend nodes to negotiate SSL. In contrast, when in intercept mode,
Achilles will pretend to be the server and negotiate two SSLsessions, one with the client
browser and another with the web server. As data is transmitted between the two nodes,
Achillesdecrypts the data and gives the user the ability to alter and/or log the data in clear text before
transmission.
Brutus: A network brute- force authentication cracker :
http://www.hoobie.net/brutus/
This Windows-only cracker bangs against network services of remote systems trying to guess passwords
by using a dictionary andpermutations thereof. It supports HTTP, POP3, FTP, SMB, TELNET, IMAP,
NTP, and more. No source code is available. UNIX usersshould take a look at THC -Hydra.
Fragroute: IDS sy stems' worst nightmare :
http://www.monkey.org/~dugsong/fragroute/
Fragroute intercepts, modifies, and rewrites egress traffic, implementing most of the attacks described
in the Secure Networks IDSEvasion paper. It features a simple ruleset language to delay, duplicate,
drop, fragment, overlap, print, reorder, segment, source-route, or otherwise monkey with all
outbound packets destined for a target host, with minimal support for randomized orprobabilistic
behaviour. This tool was written in good faith to aid in the testing of intrusion detection systems,
firewalls, and basicTC P/IP stack behaviour. Like Dsniff, and Libdnet, this excellent tool was written by
Dug Song.
HTTP Hacking :
http://www.immunitysec.com/resources-freesoftware.shtml
5. Spike Proxy is an open source HTTP proxy for finding security flaws in web sites. It is part of the
Spike Application Testing Suiteand supports automated SQL injection detection, web site crawling,
login form brute forcing, overflow detection, and directorytraversal detection.
