Industry Note

Linux and National Security

As the open source industry grows and becomes more widely accepted, the use of Linux as a secure operating system is becoming a prominent choice among corporations, educational institutions and government sectors. With national security concerns at an all time high, the question remains: Is Linux secure enough to successfully operate the government and military's most critical IT applications?

The United States government sure thinks so. A recent survey conducted by the Mitre Group found 251 Department of Defense deployments of Linux and other open source software. Not only is the United States government sponsoring hundreds of open source projects, it has been reported that open source applications have become major components in the IT infrastructure at the Pentagon.

Proprietary software advocates are currently stirring a debate on whether using Linux in matters of national defense is appropriate. It is their opinion that the availability of the source code for open source applications and the unknown origins of the code can lead to subversive content being deliberately placed into critical codes and putting the security of our entire country at risk.

What makes this debate illogical is the fact that there is not a single mainstream operating system, proprietary or open source that in its current state should be used to run critical national security applications. Any chosen system would have to be adjusted and re-worked to be a proper fit for the government's most critical IT needs. However, assuming the government is turning to Linux for national defense applications, the availability of the source code is exactly what makes Linux the obvious choice. Linux and other open source applications provide the freedom to customize programs to suit specific requirements, a liberty unfounded in proprietary systems. If the security provided by a particular installation is not sufficient it can be modified to ensure the highest levels of protection.

Additionally, the United States government, with special regard to the Department of Defense, puts security and confidentiality to the highest standard. Any code chosen for critical government or military systems must undergo countless hours of analysis and vulnerability assessment before it will even be considered for testing. To imply that our government has not considered the risks of Linux and other operating systems alike and is using insecure infrastructures of any kind is to insult the intelligence and capability of our government and military to protect its citizens.

Linux is not an invitation for IT terrorism, but quite possibly a first step towards preventing it. Linux incorporates a "defense-in-depth" approach to security, meaning robust security measures are implemented at every level of development and deployment. Not relying on obscurity, like closed-source counterparts, Linux truly focuses on the security of the system and its capabilities and strengths continue to improve, surpassing those of proprietary vendors like Microsoft.

The open source approach, however, affords users a substantial number of resources from developers in the community to ensure that even seemingly insignificant security flaws are properly fixed. The unfailing group effort and dedication of the open source community continuously results in vulnerabilities being identified and patches being released more rapidly, mitigating potential security risks before negatively affecting the end user.

Due to the consistent occurrence of security issues circling Microsoft, Linux has made its way into the mainstream and is becoming more widely accepted every day. Providing customers with a reliable, scalable platform, Linux offers a solid budget friendly alternative to those offered by proprietary vendors without sacrificing functionality and power.

Q. I have been hearing a lot about honeynets and their relevance to Internet security. What exactly are they?

A. A honeynet is a network strategically placed behind a reverse firewall used to identify hackers during an attempted intrusion. Intended to be compromised, honeynets are designed to confine and control all inbound and outbound traffic and analyze it for malicious activity. In many cases, honeynets are set up to give the intruder the look and feel of a real system, leaving them unaware they are being monitored and allowing administrators to analyze techniques and pinpoint potential vulnerabilities within a system.

In regards to security, honeynets are particularly useful because they can provide all necessary information regarding vulnerabilities and compromises within a network, allowing administrators to proactively correct vulnerabilities and thwart potential compromises before any damaging activity can take place.

Hints & Tips from Experts

Understanding & Preventing Denial of Service Attacks -- Guardian Digital is pleased to provide Behind the Shield readers with informative expert advice on what network security really means. Each month a new topic of interest will be chosen to supply you with useful tips and information not offered elsewhere. This month, we'll have a brief discussion on understanding and preventing denial of service attacks.

A denial of service (DoS) attack is defined as an attempt by a hacker to prevent authorized users from utilizing a specific service. A successfully executed DoS can disable any computer on a network, which depending on the network structure and the function of the workstation, could cause serious damage to an organization's IT infrastructure, resulting in loss of system productivity and ultimately loss of revenue.

Here are resources we consider to be the best available for information on preventing a DoS
