Benefits

  • Keep the bad guys out of your Windows PC.

  • For the advanced user, WIPFW means the difference from standard firewall control and complete firewall control.
  • 6) GnuPG

    Not to be confused with PGP, GnuPG is encryption tool for those who value the security of maintaining privacy, but wish to do with while adhering to the vision of the GNU software perspective.

    Features of the GnuPG include being able to decrypt PGP 5-7 messages, multi-language support and being able to do this without needing any patented algorithms. There is also something to be said about the integrated support with HKP keyservers as well.

    Benefits

  • Is GNU friendly, which is always a bonus. To others, it is a must.

  • GnuPG is compatible with PGP on both Windows and Linux.

  • Provides optional anonymous message receivers.
  • 7) Wireshark

    This list would simply not be complete without props to Wireshark. Considering how many attacks happen each day on our networks without us even realizing it, knowing where we are most vulnerable is absolutely key.

    Wireshark provides its users with the ability to scan pretty much any potentially vulnerable protocol you can think of. Providing deep inspection of each protocol, you can easily access just how well protected your network assets actually are.

    Perhaps the biggest eye opener is just how weak WPA encryption is by itself can actually be. Hence why I tend to lean with the creation of using a "HoneyBucket" in which I can have a little fun with those who dare toy with me in my domain...but that is for another article.

    Benefits

  • Control over your network. Catch security concerns before they become a real problem.

  • Solid VoIP analysis.

  • Verify uptime and spot patterns in any network downtime.

  • Watch out for specific packet leaks while outputting the results into a readable format.
