Russian cyber criminals were able to hack the DNC despite its security defenses and very high level of intelligence. Small and medium sized businesses are at a much greater risk of experiencing an email-related attack. Is your company prepared?

Cloud technology and Linux-based cloud services are becoming increasingly popular due to the various benefits they offer in regard to security, efficiency, flexibility and convenience.
Open source programs and solutions offer many advantages over proprietary alternatives including better quality, higher levels of security, superior flexibility, lower costs and a thriving community surrounding open source development.
In this interview, Dave Wreski discusses Guardian Digital's highly effective email security solutions and the myriad advantages of investing in these solutions to secure your email.
System administrators are aware as how important their systems security is, not just the runtime of their servers. Intruders, spammers, DDOS attack, crackers, are all out there trying to get into people
With the significant prevalence of Linux web servers globally, security is often touted as a strength of the platform for such a purpose. However, a Linux based web server is only as secure as its configuration and very often many are quite vulnerable to compromise. While specific configurations vary wildly due to environments or specific use, there are various general steps that can be taken to insure basic security considerations are in place.
Thanks so much to Peter Smith for announcing on linuxsecurity.com the release of his Linux Network Security book available free online. "In 2005 I wrote a book on Linux security. 8 years later and the publisher has gone out of business. Now that I'm free from restrictions on reproducing material from the book, I have decided to make the entire book available online."
Using password guessing as an attack vector. Over the years we've been taught a strong password must be long and complex to be considered secure. Some of us have taken that notion to heart and always ensure our passwords are strong. But some don't give a second thought to the complexity or length of our password.
This is perhaps the easiest authentication helper to configure in Squid, but also the most insecure. The biggest problem with Basic is it transmits username and password in clear text, hence very susceptible to network sniffing or man in the middle type attacks. The only reason I
Digest AuthenticationDigest Authentication hashes the password before transmitting over the wire. Essentially it sends a message digest generated from multiple items including username, realm and nonce value. If you want to know more see (RFC 2617).
The Survivability and Information Assurance (SIA) course was originally developed by a team at Carnegie Mellon, led by Lawrence Rogers (https://www.cert.org/sia/). Back in 2010, I requested a license to continue the development of the course because it provides useful information on Information Assurance. Also, this course will always be freely available for anyone to use in the classroom or self-study. There are three parts to the LearnSIA curriculum.
This article full of examples will show you various ways to test services secured using sec-wall, a feature-packed high performance security proxy. We'll be using cURL, a popular Linux command line tool and PycURL - a Python interface to cURL. As of version 1.0, sec-wall supports HTTP Basic auth, digest auth, custom HTTP headers, XPath-based authentication, WS-Security & SSL/TLS client certificates and each of the options is being shown below.
sec-wall, a recently released security proxy is a one-stop place for everything related to securing HTTP/HTTPS traffic. Designed as a pragmatic solution to the question of securing servers using SSL/TLS certificates, WS-Security, HTTP Basic/Digest Auth, custom HTTP headers, XPath expressions with an option of modifying HTTP headers and URLs on the fly.
