What The Dickens Can I Do To Secure My Servers?

Posted February 9, 2012    Peter McCalister

“It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness…” these opening words of A Tale of Two Cities (1859), a novel by Charles Dickens, have always stayed with me. While these words were written over 150 years ago they resonate with me when I talk to IT security professionals. There is plenty of technology focused on IT security and yet through accidental or intentional misuse of privilege, data breaches still occur. Does our current age of security wisdom have us acting foolishly believing that our systems and data are secure? Do the security breach headlines reflect the weaknesses in IT security implementations?

Privilege access can be controlled and your critical business systems can be protected. Implementing least privilege for UNIX, Linux and Mac OS X systems will provide more centralized and better protection of your systems and data. Implementing least privilege will ensure that your staff doesn’t access systems using root and puts the checks and balances in place through centralized logging.

Many organizations use sudo as the first step to allow users to run programs with the security privileges of root. This is a good first step, however many organizations find that the manageability and security of sudo won’t meet their needs. The need to go to each machine to update sudoer files and to collect logs hinders the productivity of system engineers. The ability for the super user to alter sudo logs just doesn’t meet the security requirements of many organizations. What is required is a simpler more secure method to secure privileged access. Implementing a robust least privilege solution for UNIX, Linux and Mac OS X will provide centralized accountability, management and reporting and meet the compliance requirements of PCI DSS, HIPPA, FISMA and other regulations.

“Security can only be achieved through constant change, through discarding old ideas that have outlived their usefulness and adapting others to current facts.”
– William O. Douglas (1898 – 1980) U.S. Supreme Court Justice

GHOST Vulnerability…Scary Indeed

Posted January 28, 2015    BeyondTrust Research Team

A vulnerability discovered by Qualys security researchers has surfaced within the GNU C Library that affects virtually all Linux operating systems. The vulnerability lies within the various gethostbyname*() functions and, as such, has been dubbed “GHOST.” GHOST is particularly nasty considering remote, arbitrary code execution can be achieved. In an effort to avoid taxing DNS lookups, glibc developers introduced…

Posted January 27, 2015    Dave Shackleford

Is 2015 the year you get a better handle on security? The news last year was grim – so much so, in fact, that many in the information security community despaired a bit. Really, the end-of-the-year infosec cocktail parties were a bit glum. OK, let’s be honest, infosec cocktail parties are usually not that wild…
