Google launches Open source sceurity tool in Beta. what’s that. Let us first understand what is open source security tool. Open source security tools are the tools that will help you to secure your systems and networks, there are thousands of these tools with both defensive and offensive security capabilities.
Here is the list of few open source security tools :
1. Nmap – map your network and ports with the number one port scanning tool. Nmap now features powerful NSE scripts that can detect vulnerabilities, misconfiguration and security related information around network services. After you have nmap installed be sure to look at the features of the included ncat – its netcat on steroids.
2. OpenVAS – open source vulnerability scanning suite that grew from a fork of the Nessus engine when it went commercial. Manage all aspects of a security vulnerability management system from web based dashboards. For a fast and easy external scan with OpenVAS try our online OpenVAS scanner.
3. OSSEC – host based intrusion detection system or HIDS, easy to setup and configure. OSSEC has far reaching benefits for both security and operations staff.
4. Security Onion – a network security monitoring distribution that can replace expensive commercial grey boxes with blinking lights. Security Onion is easy to setup and configure. With minimal effort you will start to detect security related events on your network. Detect everything from brute force scanning kids to those nasty APT’s.
5. Metasploit Framework – test all aspects of your security with an offensive focus. Primarily a penetration testing tool, Metasploit has modules that not only include exploits but also scanning and auditing.
6. OpenSSH – secure all your traffic between two points by tunnelling insecure protocols through an SSH tunnel. Includes scp providing easy access to copy files securely. Can be used as poor mans VPN for Open Wireless Access points (airports, coffee shops). Tunnel back through your home computer and the traffic is then secured in transit. Access internal network services through SSH tunnels using only one point of access. From Windows, you will probably want to have putty as a client and winscp for copying files. Under Linux just use the command line ssh and scp.
7. Wireshark – view traffic in as much detail as you want. Use Wireshark to follow network streams and find problems. Tcpdump and Tshark are command line alternatives. Wireshark runs on Windows, Linux, FreeBSD or OSX based systems.
8. BackTrack – an Ubuntu based Linux distribution that is configured with hundreds of security testing tools and scripts. Backtrack is well known with penetration testers and hobbyists alike.
9. Nikto – a web server testing tool that has been kicking around for over 10 years. Nikto is great for firing at a web server to find known vulnerable scripts, configuration mistakes and related security problems. It won’t find your XSS and SQL web application bugs, but it does find many things that other tools miss. To get started try the Nikto Tutorial or the online hosted version.
10. Truecrypt – encrypt all the things. Truecrypt is a strong encryption utility that can encrypt entire volumes or create an encrypted container within a file system. Use Truecrypt to protect your flash drives. If it gets lost, even the NSA will have trouble reading the data.
Google wants to make “fuzz testing” — providing random data inputs to programs — a standard part of open source development. (Fuzzing or fuzz testing is a software testing technique, often automated or semi-automated, that involves providing invalid, unexpected, or random data to the inputs of a computer program. The program is then monitored for exceptions such as crashes, or failing built-in code assertions or for finding potential memory leaks. Fuzzing is a form of random testing commonly used to test for security problems in software or computer systems. For the purpose of security, input that crosses a trust boundary is often the most interesting. For example, it is more important to fuzz code that handles the upload of a file by any user than it is to fuzz the code that parses a configuration file that is accessible only to a privileged user.)
Fuzz testing is often employed as a black-box testing methodology. The technique can only provide a random sample of the system’s behavior, and in many cases passing a fuzz test may only demonstrate that a piece of software can handle exceptions without crashing, rather than behaving correctly. This means fuzz testing is an assurance of overall quality, rather than a bug-finding tool, and not a substitute for exhaustive testing or formal methods.
As a gross measurement of reliability, fuzzing can suggest which parts of a program should get special attention, in the form of a code audit, application of static code analysis, or partial rewrites.
Google just launched a beta program for OSS-Fuzz, a project on GitHub. It seeks to help standardize modern fuzzing techniques and combine them with a distributed execution model that can scale as needed.
This technique can be used to ensure popular open source components — specifically those considered to be critical parts of the global IT infrastructure — are stable, secure and reliable.
Errors like buffer overflow and use-after-free can have serious, widespread consequences when they occur in critical open source software,”. “These errors are not only serious, but notoriously difficult to find via routine code audits, even for experienced developers. That’s where fuzz testing comes in. By generating random inputs to a given program, fuzzing triggers and helps uncover errors quickly and thoroughly.”
What is the function of OSS-FUZZ is it will combine different fuzzing engines — starting with libFuzzer — and other components in a scalable distributed execution environment leveraging the ClusterFuzz project.
Google said the tool, which will provide continuous fuzz testing for select projects, was developed over a period of years in conjunction with the Core Infrastructure Initiative community. The project is critical to IT infrastructure.
