Access remote network services with SSH tools

By Keith Fieldhouse on November 11, 2008 (9:00:00 AM)

You probably rely on the services on your own private network -- wikis, mail servers, Web sites, and other applications you've installed. What happens when you have to leave the friendly confines of your network? With minimum exposure and few simple tools, you can get all of the comforts of home anywhere you can find an Internet connection.

Automatically mount encrypted filesystems at login with pam_mount

By Ben Martin on November 06, 2008 (4:00:00 PM)

The pam_mount project lets you unlock an encrypted filesystem automatically when you log in. The same password used to log in is used as the key to unlock the encrypted filesystem, so you only need to type it once. Using this method, you can easily share a laptop and have only a single user's home directory unlocked and mounted when he logs in. And pam_mount can mount any filesystem, not just encrypted filesystems, so you can use it, for example, with an NFS share that you are interested in but which you might not like to leave mounted when you are not logged in.

Portrait: Metasploit godfather H.D. Moore

By Tina Gasperson on October 30, 2008 (6:00:00 PM)

The Metasploit Project develops a set of security tools to create and execute exploit code on remote computers. Some people say Metasploit makes the job easier for black hat hackers who attack networks looking for vulnerabilities to take advantage of; others says the tool helps network security administrators do a better job of finding and repairing weaknesses before the bad guys get to them. H.D. Moore, the 20-something creator of the Metasploit Project, says it all depends on your perspective.

Four password lockers that can help you keep your Web logins secure

By Ben Martin on October 21, 2008 (9:00:00 AM)

It is good practice to use a different password for each Web site you need to log in to. Good passwords tend to be long and contain a wide selection of characters. That can make remembering all your passwords difficult. But you can make things easier on yourself by storing passwords for various Web sites in an encrypted file on your computer. I'll take a look at a four programs that give you easy access to your passwords when you need them and protect the password file itself against compromise.

Security scans with OpenVAS

By Federico Kereki on October 09, 2008 (9:00:00 AM)

As important as security is, remaining current with every development is hard, and evaluating possible vulnerabilities across a network can be quite a chore. You need a way to both automate tests and make sure you're running the most appropriate and up-to-date tests. Open Vulnerability Assessment System (OpenVAS) is a network security scanner that includes a central server and a graphical front end. The server allows you to run several different network vulnerability tests (NVT) written in Nessus Attack Scripting Language (NASL), which OpenVAS updates frequently.

Track your missing laptop with Adeona

By Nathan Willis on September 23, 2008 (9:00:00 PM)

Almost every laptop on sale today comes equipped with the Kensington security slot on the side or back, through which you can connect a theft-deterring locked steel cable. The system's down sides are (a) that a would-be thief can damage or destroy your equipment trying to yank the cable out, and (b) that you have to buy the cable separately. As an alternative, the free software utility Adeona won't preemptively deter theft, but it will help you track down your stolen equipment and better the chances of its recovery by police.

Securing your network with PacketFence

By Cory Buford on September 23, 2008 (4:00:00 PM)

Network access control (NAC) aims to unify endpoint security, system authentication, and security enforcement in a more intelligent network access solution than simple firewalls. NAC ensures that every workstation accessing the network conforms to a security policy and can take remedial actions on workstations if necessary. For example, NACs can check if a workstation has antivirus software installed and, if not, NAC will limit the workstation's access to the network. In some cases, if NAC is capable of remedial measures, it can force-install an antivirus program on the workstation so that it will conform to the security policy. Although NAC can improve the security of your environment, most commercial NACs cost several thousand dollars. However, using NAC does not need to be that expensive. PacketFence, a free open source NAC application, gives you the security of NAC for free.

Protecting your network with Strata Guard Free

By Cory Buford on September 12, 2008 (9:00:00 AM)

Being connected to the Internet means exposure to what the outside world has to offer -- including the undesirable elements. Every time you connect to the Internet, you're exposed to threats that can compromise your network's security. Although network security solutions have evolved in recent years, so have network attack techniques. To prevent ever-evolving attacks from compromising your network, you must preemptively block malicious traffic before it enters your network. Free, open source programs, such as Snort, can do the job, but setting up a full intrusion detection system (IDS) sensor, especially in an enterprise network, takes time and isn't very user-friendly. StillSecure's Strata Guard Free can be your front line of defense to face outside threats without as much hard work.

Protecting your MySQL database from SQL injection attacks with GreenSQL

By Ben Martin on August 25, 2008 (4:00:00 PM)

SQL injection attacks can allow hackers to execute arbitrary SQL commands on your database through your Web site. To avoid these attacks, every piece of data supplied by a user on a Web form, through HTTP Post or CGI parameters, or other means, must be validated to not contain information that is not expected. GreenSQL is a firewall for SQL -- it sits between your Web site and MySQL database and decides which SQL statements should and should not be executed. At least that's the idea -- in execution, I found some open doors.

Set up your firewall with Firewall Builder

By Ben Martin on August 14, 2008 (9:00:00 AM)

Firewall Builder (fwbuilder) is a graphical application that can help you to configure IP traffic filtering. It can compile the filtering policy you define into many specifications, including iptables and various languages used by Cisco and Linksys routers. Separating the actual policy you define and the implementation in this way should let you change what hardware is running your firewall without having to redefine your policy for that platform.

Smart ACL management with Eiciel

By Shashank Sharma on June 18, 2008 (4:00:00 PM)

The traditional file permission model, where read, write, and execute permissions are set on each file for the user, group, and others (UGO) has one drawback: It can't be used to define per-user or per-group permissions. For that, you need to employ access control lists (ACL). Eiciel is a graphical tool that integrates with the Nautilus file manager and allows for easy ACL management.
