World Wide Chaos = Local Instability

If you are like me, you are witnessing all of the violent events across the world, and wondering what comes next.

As a seasoned security person, I know that anything of significance that happens in one place, inevitably impacts everything else in one way or another.  Right now, there is increasing instability in what laws are, whether or not they are legitimate, and who will enforce their observance. This can only mean bad things for the Information Security world.

Higher levels of chaos can only be bad news for the online world, and as a result, renewed vigilance is needed now more than ever.  Tighter access rules, closer looks at logs, more attention to detail.  Certainly, complacency is an expensive luxury these days.

The well-worn statement really applies – for Information Security to be effective it needs to be right 100% of the time, but for the hacker community, they only need to be right once.

 

Are GDPR Changes Coming?

If you have been following the recent set of measures enacted by the EU for the protection of information you are probably wondering whether, given the recent BREXIT vote, what will be likelihood that the new EU Security Measures will be facing some changes in the near future.

After glancing at some of the provisions identified in the GDPR, I’ve been wondering whether some of the strict measures it spells out may end up being changed or watered down in light of this new shift of emphasis within the EU.

Although the BREXIT vote was mere days ago, it seems that there is a broader movement on the continent by other EU countries who are yearning for the days where they had more autonomy.  That being the case, holding together a set of measures of the magnitude of the GDPR, may prove more difficult than the crafters may have thought.

The months ahead will tell whether this will be the case.  I for one am always interested in seeing whether such far-reaching measures ever fully succeed, or just act as a place-holder for the next round of measures.  Clearly, the GDPR is a move in the right direction, but whether or not there is teeth in it, and that the teeth that it has can effectively be used to protect privacy may be an open issue.

As the old saying goes, “anyone can steer a ship on quiet seas, but it takes an experienced hand to handle the wheel during a storm”.

 

How critical is patching these days?

A good number of years ago, I was engaged as a security consultant for local Cincinnati Fortune 100 company.  Many of the tasks I performed were fairly routine, and there was a large staff of system administration specialists to interact with, which made my job much easier.

Among other things, I was involved in some compliance processes for the many servers at that firm.  Their server population was quite diverse, running the gamut from different generations of Windows, Windows Server, and a myriad of Unix flavors.

As part of the compliance monitoring, an automated system scanning scheme was implemented.  This system worked in concert with the tightly focused scanning that was already occurring on those systems managed by a third-party security monitoring firm.  Things were split up for economic reasons.

As part of the scanning process, reports were automatically generated for each system scanned, and the individual reports were emailed to the specific system’s SA along with copies to the security team.

Over the weeks following the implementation, it became hard to ignore the fact that some extensive patching would be needed to ensure all of the systems and servers would be up to the most recent patch levels.  Also, there were many questions about whether a particular patch was necessary, and whether the patch actually fixed the problem (and also, whether that patch might ‘break’ things).  I’m sure anyone who has ever focused on this will agree these sorts of concerns are important when it comes to running a reliable data center.

The primary concern that the data center managers had at that particular time was the emerging “Day 0” malware concern.  For those of you who aren’t aware of what this is here is a brief explanation:

There is a very large community of malware producers (read: “the bad guys”) out in the world and on the Internet.  Between the time a new vulnerability is identified and affected systems can be patched to counter the threat, there is a short window of opportunity (in fact, the window is “open” as long as the world is oblivious about the vulnerability!).  Systems are most vulnerable during this period because corrective patches have not been developed to counter the threat, and aids such as  anti-virus software haven’t been sensitized to detect the threat either.

For system administrators, system patching is probably the surest method available to maintain some defense against such rapidly emergent threats.

Continuing, besides the whole question of whether or not a particular patch has been created in response to a vulnerability, industry news of such vulnerabilities circulates slowly, and mostly in specific communications channels.  Vendors create patches for discovered vulnerabilities and release them as quickly as possible, however, often word of these fixes is also slow to emerge.

Returning to the situation I was describing, our team spent some time brainstorming about what we could do.  We knew that there were subscription sources that produced vulnerability updates, and in addition to that, many of the major server suppliers produced alert emails whenever patches were released to the field.  Slowly we began to piece together a patching information management system to improve our odds at having systems patched.

Fast-forward to today.  If you are a Windows user you know about “patch Tuesday” which is the day that Microsoft releases its patches.  Every week patches are “pushed” out and the update tools on endpoint systems dutifully apply those patches.

Other systems, such as Linux hosts and Mac’s, perform on-demand updates where patches are periodically fetched and applied.  There are a good number of applications that watch over the ‘patch’ domain and provide the tools to apply those patches as well.

Problem solved, right?

Not really – there are a host of concerns involved with automatic patching systems.  Some patches are applied and work just fine.  Some patches cause things to break, and some just make things worse (or even, don’t work as advertised!)  The point being that “fire and forget” patching has its shortcomings, and for some, the shortcomings are threats in and above all.

So the question to the audience is whether or not there are satisfactory patch management solutions these days?  I am aware that there are a number of companies to perform these services, so I’m curious as to the level of effectiveness they may have.

One last point.  In their 2014 DBIR report, Verizon’s analysts pointed out that many of the exploits used by hackers were ‘old’, and that had those systems been properly patched, the penetrations would never have happened.  I believe that the Patching Dragon has yet to be slain.

New Blog – “First Light”

In the astronomical trade, “First Light” is a term used to describe the premier of the first fruits of a particular telescope or system’s operation.  The term has been hijacked by writers such as myself to apply also to the establishment of things of smaller import, in this case, my humble blog.

The Risky Undertaking is a blog focused on the areas of Risk Management, Privacy Issues and more recently, the whole question of Cyber Security.  Essentially it will be the voice of my personal consultancy practice and it will be the place where I hope to inform, promote, and also “sound off” on topics of interest in this area.

About myself:

My name is Richard and I am the owner / operator of this blog – –

I have worked in the IT and Security business areas for several decades.  The bulk of my work has been done in the Southwestern Ohio area, but I have traveled and worked at times elsewhere in the US.

My technical interests are diverse and they run the gamut from bread and butter security and compliance work on down to more concrete areas such as programming ARM based processors to do specific “gadget” tasks.

Besides my independent consulting work, I am also a Microsoft partner, a Cisco partner and a Symantec partner and as a result I am also able to sell their products to my clients (present and future).

I should also point out that my personal humor is somewhat dry, along the lines of the old Monty Python skits of the 1970’s, so I apologize in advance if that comes through in my posts.

Why should you come here?

In anticipation of this question, here are a few reasons:

  1. If you are looking for some alternative perspectives on security, cyber and risk topics.
  2. A “little guy’s” view of the industry as it relates to those areas of my interest.
  3. Views tempered by my long involvement with this industry.

I could probably think of a few more, but that should be sufficient for the moment.

Please stay with us in the weeks and years to come and hopefully I’ll occasionally provide you with some good “stuff”.
