[Infographic] 4 Steps to Secure Shell Key Management Bliss

Secure Shell is an essential component in the day-to-day functions for many IT professionals. In fact, a recent Forrester study found 82% of organizations use Secure Shell and 68% consider Secure Shell important or critical to their business.

While most enterprises use Secure Shell to run and maintain essential business processes, few have ever examined their deployment process of Secure Shell. Secure Shell keys are often created without any oversight or management, and the elevated privileges that accompany Secure Shell keys means there is a higher risk for data breaches and compliance…

Potential Pitfalls of MAS TRM Guidelines

Monetary Authority of Singapore (MAS) revised its Technology Risk Management Guidelines (TRM) in June 2013. Financial Institutions (FI) operating in Singapore have since been reviewing the guidelines against their own security procedures and infrastructures, to determine necessary enhancements to match the new requirements. While the guidelines are not legally binding, MAS uses them when performing risk assessments of the…

Heartbleed and Shellshock – Different Vulnerabilities, Same Lesson

Just last month we hosted a webinar called “Heartbleed – You Stopped the Bleeding but Did You Fix the Problem?”. Heartbleed allows an attacker to retrieve the contents of memory from vulnerable servers. As a result, any private credentials that might have been resident in memory can no longer be considered private. That is why many enterprises and public facing web services advised their users to change their…

Elliptic Curves and More: Universal SSH Key Manager Version 1.3.3

The latest version of Universal SSH Key Manager brings an important update: support for elliptic curve cryptography (ECC) keys. If you’re not familiar with ECC, suffice it to say that it’s an approach to public-key cryptography based on elliptic curves which is said to provide the same level of security as traditional RSA or DSA but with smaller key sizes while also using faster and lighter…

Heads Up for Federal CISOs and CIOs: NIST Publishes Guidelines for SSH Key Management

For those of us who follow the activities of NIST, yesterday marked the arrival of a remarkable document with a characteristically bland NIST-style title:  “Security of Automated Access Management Using Secure Shell”. The release of this report (NIST Interagency Report 7966) has great significance for organizations that use Secure Shell – which is just about every medium to large enterprise, most government agencies and many large non-profits. So what is…

Black Blob of Death Threatens Data Center Security

Researchers at SSH Communications Security recently uncovered a serious security vulnerability that impacts data centers in the vast majority of banks and financial institutions. Okay, so admittedly, it almost sounds like a story from The Onion or some made up news by a bored blogger. But this really isn’t a satirical post about the over-hyping of security issues or fake news. The Black Blob of Death is…

With “Backoff” POS Malware, Attackers Use Your Security Tools Against You

Yesterday the US Department of Homeland Security issued a warning to US businesses against a new POS malware attack called “Backoff”. The attackers are targeting common remote access systems like Microsoft Remote Desktop, Apple Remote Desktop, Chrome Remote Desktop, Splashtop, Pulseway and join.me. To make matters worse, this little bug is difficult for anti-virus software to…

Snowden Calls On Employees To Leak Company Secrets

During the Hackers On Planet Earth (HOPE) conference, Edward Snowden and Daniel Ellsberg called on insiders (employees) to spill corporate and government secrets.  Snowden is calling for the development of encryption and obfuscation tools to make this easier. The goal is to anonymously expose malfeasance without any repercussions. They believe that people should be able to do this without paying any price and without being held accountable. Superficially this all sounds like a good idea, but who gets to decide what should be leaked or stolen and what constitutes improper behavior?  What else could be leaked or…

Now Distributed People Can Stop Complaining About z/OS

Many companies have a mix of distributed platforms and mainframes (z/OS) in their environment. Most distributed users do not understand z/OS too well and don’t want to, but they still have to deal with it. This is a frustrating reality for distributed and z/OS users alike. That is until now!

We have come up with a solution for this type of problem based on customer feedback. Distributed and mainframe can now securely submit JCL jobs to z/OS by simply executing a put command from any distributed or z/OS platform.   As requested, the distributed user does not need to know anything about z/OS to do this. Your z/OS system programmer can write some reusable JCL jobs for your distributed users to use, maybe with some easy to change parameters. Then any distributed user can submit a job from any platform or client without ever logging into a z/OS…

The Mainframe and IDM

Identity Management Projects always result in lower costs and Streamlined Security Administration.

Where have you heard that one before?

Since the mid 1990's there has been a talent drain in the Mainframe Security Administration field.   Concerned IT Management, looking for ways of filling the void basically figured that automating User Provisioning and Credentials could fill the void. To meet the Customers needs Large Software Companies developed centralized Identity and Access management tools. In terms of the Mainframe it meant putting a common Windows GUI in front of ACF-2 Top secret and RACF for inexperienced Administrators to drag and drop ID's and…

Backdoor SSH Root Key Snafus Much More Common Than You Think

It appears as though a hard-wired Secure Shell private key has created a bit of a kerfuffle for folks running Cisco's VoIP manager This one made it in the headlines but because the affected system was identified and limited in scope to a single product line, remediation steps can be quickly undertaken and the impact minimized. Now imagine if an entire data center had unknown or misplaced private keys floating about. Well, it is more common than you think and the risks are far greater because it’s not just a single product that has the issue, every server in your environment has the…

All Threats are Insider Threats

Back in the day when the enterprise security model was a hardened perimeter protecting the internal "trusted" network, security vendors seized on the notion that businesses need protection from their employees - the insider threat.

Studies were commissioned to show how much malicious insiders were costing businesses. More recent studies indicate the majority of data breaches are carried out by…
