My ambition was to implement a small (better tiny) appliance for monitoring network health and network resources, short and longtime trends, running under VMware Server or VMware ESX. So I had an eye upon all components which are implemented on the system, to be as leightweight as possible. This was also the reason why no SQL DBMS based software was used.. The appliance is based on Ubuntu Jeos LTS (8.04.3 at the time of this writing). Almost all used components are from the related repositories. This tutorial shows how the appliance was implemented. I do not issue any guarantee that this will work for you! Used components: Ubuntu 8.04.3 JeOS as OS Nagios 2.11 for monitoring and alarming Smokeping 2.3 to observe latencies and paketloss MRTG 2.14.7 to observe networktraffic's tendencies RRDTool 1.2.19 as Round-Robin Database for storing all measurement data Lighttpd 1.4.19 as fast, lightweight webserver frontend weathermap4rrd for illustrating the networkweather ssmtp as extremely lightweight MTA for maildelivery The link for this article located at HOWTO Forge is no longer available. . Learn how to set up a lightweight network monitoring appliance using Ubuntu Jeos, from installation and updates to configuring monitoring tools and securing your setup.

To stop data leakage, try a two-punch strategy that combines outbound content-monitoring tools with digital rights-management appliances. A disgruntled employee here, a careless one there, and just about any enterprise can find itself facing a mountain of trouble from confidential information made public. Help is at hand. Armed with increasingly sophisticated outbound-content monitors, information security officers finally have the weapons they need to conquer the threat of data leakage. . Does the IT staff represent a bigger security threat than business unit employees? Read the story, place a vote and share your opinion. Outbound-content monitoring - also known as data- or information-leakage prevention - came of age in the past year. The devices "have reached a state where they can be a fundamental part of everyone's network," says Josh Levine, managing director at Kita Capital Management, former CTO at E*Trade Financial and board member for device start-up Securify.

Most security breaches by insiders are unintentional. They come from employees who make ill-advised or uninformed choices regarding storage of their passwords, the Web sites they visit, and the E-mails they send. The Computing Technology Industry Association's annual survey on IT Security and the Workforce trends, to be published in March, indicates that nearly 80% of corporate security breaches are caused by computer-user error. . One in four outbound E-mails poses a legal, financial, or regulatory risk to the sending company, according to a 2005 survey conducted by Forrester Research and messaging security software maker Proofpoint Inc. of 332 IT executives and managers. Companies expect insider risks to grow, and nearly half of survey respondents plan to deploy technology to monitor Web mail or instant messaging to combat these threats.

A significant fraction of emails sent externally—about a quarter—harbors potential legal, financial, or compliance risks for the originating organization, exposing concealed dangers..

The paths may be slightly different on a Linux system, but it's otherwise the same. "Over a year ago, I had an interesting job of tracking down how a root superuser account vanished. Once I was on the system, it appeared that the issue was not malicious and I enjoyed the detective work tracking down the problem. I searched RADIUS accounting logs, httpd logs and process accounting logs and I was able to pin-point the problem (and the user) within seconds: a faulty CGI provided a way for the root account to be removed. One of the tools I used was lastcomm -- the command for showing last commands executed. This article covers the basics of enabling process accounting and shows a few examples of using lastcomm and sa to read and use the accounting data. These tools can help monitor user activity and system usage." See also the Process Accounting HOWTO The link for this article located at BSD Today is no longer available. . Implement process accounting on BSD to track user activity using `lastcomm` and `sa` commands for effective monitoring and analysis.
