Are you a victim of endemic packet loss?

If you’re reading this blog then there’s a good chance that you already recognise the importance of highly accurate packet capture within your monitoring and security infrastructure(s) which is music to our ears. But as most professionals know, actually achieving zero packet loss is far from straightforward.

The bit that most people miss is that it doesn’t matter how good your  software application is, if it’s missing packets then the results will be nonsense.  To achieve 100% packet analysis – which is actually a more precise definition that 100% packet capture – you need to take a step back and look at the whole end to end journey that a packet takes between the wire and the application.  If you are passively monitoring stageful traffic, one packet lost can void analysis for the entire session, and if that session is days long, then you loose the lot, or if you are going to stand up in court to validate some analysis, then you need to know you have it all.

IDS is dead. Long live IDS.

The ‘in band’ v’s ‘out of band’ debate continues to rage and we find ourselves discussing the pros and cons of IPS v’s IDS with customers on a regular basis. To this day, we’re still surprised by the number of IPS implementations that we discover deployed in ‘passive mode’, with the engineers responsible admitting to being “too scared to turn blocking on”.

The reality is that IPS and IDS are different horses which are designed for different courses.The debate isn’t IDS or IPS, its actually IPS and/or IDS.  IPS are useful for organisations that don’t have the local resources (typically in the form of a SOC) to manage infections and outbreaks within the network. A high performance IDS is the right solution for those that do. At Endace we think of IPS as a kind of ‘SOC in a box’.

Why it feels great to be ‘Application Intelligent’

This week we inked a strategic partnership agreement with our friends at Vineyard Networks from Kelowna up in British Columbia, Canada. Vinyard’s expertise lies in helping organisations, like Endace, become Application Intelligent. Their software, which partners license and integrate, is a combined deep packet inspection / deep flow inspection engine that recognises thousands of different application layer (Layer 7) protocols and classifies packets accordingly. Basically it adds metadata that says “this is Facebook” or “this is Skype” to every packet or stream that it looks into.

And why is this capability relevant to us? Well, put it this way, for anyone working in network operations, or network security for that matter, it’s the difference between watching football on a black and white CRT and full HD 1080p.

Nick Harvey MP calls for an ‘All of Society Approach’ to Cyber Security

Tuesday the 5th July saw the passing of the 6th annual National Security Conference in London. As a supporter of the event we were lucky enough to be able to join the likes of  Nick Harvey, Minister of State for the Armed Forces and Neil Thompson, Director, Office of Cyber Security & Information Assurance, Cabinet Office on the podium to share our perspectives on national cyber security and the role that central government plays in protecting citizens from both physical and cyber attack.

It was an extremely well attended event with high quality presentations and informed discussion amongst the 350 security and counter-intelligence professionals that attended. Nick Harvey opened the event with a great keynote that touched on a number of important themes that are close to our hearts.

Brand matters

As a nation we’re obsessed by brands. They’re everywhere and whether we like it or not, in today’s ultra-connected world, they matter – government agencies are hiring branding agencies to help them manage their public ‘image’. If you look closely at some corporate accounts ‘brand’ is starting to appear as an asset on the balance sheet. Whether you agree or not isn’t the point, the fact is that they are and that matters.

For purists (like me), brand is really just a synonym for corporate reputation. You can’t buy your way to reputation: you earn it over time. You do the hard yards and you build it piece by piece, customer by customer, recommendation by recommendation.  All the advertising dollars in the world won’t buy you brand equity (they will just buy you brand awareness). If you treat your customers like dirt, your brand will be dirt. That bit at least is very straightforward

Measuring the gap between hype and reality

Most security professionals know that what vendors claim their systems can handle (in terms of throughput) and what they can really handle are two different things. Why is this the case, why does it matter and what can you do about it?

Before diving in, it’s important to understand what ‘throughput’ really means. In layman’s terms, throughput is the amount of network traffic (measured in Mb/s or Gb/s) that a system can ‘process’ without missing events.

There are three main reasons why network security systems, such as IDSs and IPSs miss network security events:

  1. The hardware platform doesn’t show the packets to the application because it’s simply not up to the job
  2. The DPI engine (the application) isn’t fit for purpose
  3. The rule set is too simple, or too complex

As a buyer of these systems, you need to be sensitive to all three factors, as two legs does not maketh a stool [sic]

Guarding the games

National security is a big deal. We trust our elected governments to have our backs, to stop the bad guys before they act and keep us safe. It’s why we pay our taxes and vote for the people that we do. The swing from traditional ‘armed’ threats internet-borne threats has been extraordinarily rapid and created an entirely new threat landscape for our governments to deal with. Lulzsec’s recent rampage across the internet has shown in the most public way just how vulnerable we all are (governments, enterprises and individuals alike), to malicious attack from this new frontier and in many cases, just how badly prepared we truly are. Protecting national security is far harder today than it’s ever been before. At least before you could see the bad guys.

At Endace we’ve worked closely with a variety of government agencies for many years, helping to facilitate, empower and enable the activities of those responsible for keeping us safe. It’s a market that we’re proud to be associated with and one that we’re actively developing all over the world with government agencies that understand the power of the Endace Platform.

Lost in Translation: Your financial services network may have data holes… here is how to find and plug them

By Chandan Sharma – Global Managing Director for Verizon Business

Business agility is an art among a whole big bunch of science. Every financial organization has to cope with increasingly enormous amounts of data: customer data, billing data, product usage data, employee data, reference data, and, perhaps most importantly for financial markets participants, market data delivered real-time for optimal trading decisions. And, algorithmic trading has further underscored the importance real-time delivery of reliable and accurate market data for trading decisions.

You can only imagine the potential effect of finding that the information on which you were making crucial decisions was actually riddled with gaps, thus compromising the integrity of the market data upon which trading algorithms or people such as trading specialists make more informed and timely decisions. If anything is ‘lost in translation’ from market center to the algorithmic engine or the trading terminal they won’t be.

The first step towards a real EU cyber security alliance?

An article in today’s TelcomAsia online publication about EU Cyber Security caught our eye. Michael Carroll wrote an article in response to a speech made by European Digital Agenda commissioner Neelie Kroes, who spoke at a telecoms conference in Hungary earlier today. The commissioner stated categorically that weak cyber security will limit the potential of ICT to deliver social and economic benefits. Of course there’s nothing startlingly new in this statement; those in the industry have known for a long time that we’re only just starting to understand the true costs of cyber-crime and there’s a lot more to learn. What’s different this time, is that Kroes called for a joint security effort from member states and other key “allies around the world,” noting explicitly that progress made to date is not enough to achieve the “close cooperation we need.”

To capture or not to capture? Why that’s no longer a valid question

In the last week both Symantec and IBM have released their annual security surveys which provide rich insight into the volume and range of security attacks circling the Internet.

As expected, Symantec Corp in their ‘Internet Security Threat Report’ highlighted a massive increase in threat volume (286 million new threats last year), accompanied by several new ‘megatrends’ in the threat landscape. The report highlights increases in both the frequency and sophistication of targeted attacks on enterprises; the continued growth of social networking sites as an attack distribution platform; and a change in attackers’ infection tactics. In addition, the report explores how attackers are exhibiting a notable shift in focus toward mobile devices.

Specifically, Symantec identified attacks such as Hydraq and Stuxnet as posing a growing threat to enterprises in 2010. To increase the likelihood of successful, undetected infiltration into the enterprise, an increasing number of these targeted attacks are leveraging zero-day vulnerabilities to break into computer systems. As one example, Stuxnet alone exploited four different zero-day vulnerabilities to attack its targets. While the high-profile targeted attacks of 2010 attempted to steal intellectual property or cause physical damage, many targeted attacks preyed on individuals for their personal information. For example, the report found that data breaches caused by hacking resulted in an average of more than 260,000 identities exposed per breach in 2010, nearly quadruple that of any other cause. At Endace, we see the prevention of data loss as being a key driver of technology investment over the next 12 months as organisations start to really understand the reputational damage caused when private customer data goes public.
