security advisory moderate For organizations that run a self-hosted Git platform, it’s no longer just about hosting static code repositories. Today, Git servers are responsible for deployment pipelines, API tokens, SSH keys, package repositories, and the automation scripts that push code directly. Confirm that the upgrade addresses known vulnerabilities but also provides production environments. . That makes them trusted systems within the development environment and attractive targets for attackers looking to move...

Server Securitydata privacy automation
data privacy automation Every system admin has lived through the same Monday morning ritual. A queue of forty tickets, half of them password resets, permission errors, or disk space warnings that any experienced technician could resolve in under two minutes. The other half require actual judgment. For years, automation promised that software would eventually sort the two apart on its own. That promise is now being tested in production Linux environments. . Early results are reshaping how IT teams think about tier-1...

monitoring toolsNagiosnetwork monitorCreating A Lightweight Network Monitoring Appliance With Ubuntu Jeos
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. .

data protectioninformation securitymonitoring toolsStrategies To Prevent Data Leakage Using Monitoring And Rights Management
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.

security breachinsider riskemail threatsExploring Insider Risks And Email Threats In Organizations
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. The link for this article located at Information Week is no longer available. . 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 Electronic Privacy Information Center is launching a counterattack against Hollywood's efforts to crack down on student file-swapping. The privacy advocacy group is sending letters to presidents of colleges across the country, asking them to think before they install monitoring tools on university networks. "Monitoring the content of communications is fundamentally incompatible with the mission of educational institutions to foster critical thinking and exploration," EPIC wrote. "Monitoring chills behavior and can squelch creativity that must thrive in educational settings." EPIC's effort comes in response to attempts by the entertainment industry to pressure colleges into curtailing file swapping. Last month, the Recording Industry Association of America (RIAA) and the Motion Picture Association of America (MPAA) sent letters to more than 2,000 colleges, warning them that students were using school networks to trade illegal file copies. Although the letter did not overtly threaten legal action, it did ask the schools to make a "substantial effort" to stop such trading.

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. .
