GUEST ESSAY: Why the hack of South Korea’s weapons, munitions systems was so predictable

By Pravin Kothari

The disclosure that malicious intruders hacked the computer systems of the South Korean government agency that oversees weapons and munitions acquisitions for the country’s military forces is not much of a surprise.

The breach of some 30 computers of South Korea’s Defense Acquisition Program Administration (DAPA), which is part of the Ministry of National Defense, reportedly occurred last October. News reports this week indicate internal documents, including details of arms procurement for the country’s next-generation fighter aircraft, were pilfered from at least 10 of the hacked computers.

The hackers reportedly manipulated server software and succeeded in siphoning records from connected workstations. Though South Korean officials stopped short of blaming North …more

GUEST ESSAY: What your company should know about addressing Kubernetes security

By Gary Duan

Kubernetes is one of many key enabling technologies of digital transformation that has tended to remain obscure to non-technical company decision makers.

Kubernetes is an administration console — an open source project from Google that makes containerized software applications easy to  deploy, scale, and manage.

As beneficial as Kubernetes is for orchestrating containerized environments, a maturing set of security best practices must be adhered to for enterprises to ensure that their applications and data are as safe as possible from emerging vulnerabilities and exploits.

The most dangerous attacks on container environments will execute a “kill chain” of events – not striking all at once but instead through a sequence of lateral moves within the dynamic container environment to ultimately take over containers, attack Kubernetes services, or gain unauthorized access.

Attackers are shaping their attacks to take advantage of recently discovered vulnerabilities and systems which have not yet been patched or equipped to counter efforts to exploit them. In addition, the discovery of malicious ‘backdoors’ hidden in popular Docker images is another cause for concern.

Three recent examples illustrate this seemingly endless stream of vulnerabilities that attackers can leverage in a containerized environment: the Dirty Cow exploit, the Linux Stack Clash vulnerability, and the even more recently discovered CVE-2018-1002105 vulnerability in Kubernetes. Here’s how each inflicts damage: …more

GUEST ESSAY: The case for engaging in ‘threat hunting’ — and how to do it effectively

By Mike James

Modern cyber threats often are not obvious – in fact it is common for them to lurk inside a business’ systems for a long time without anyone noticing. This is referred to as ‘dwell time’, and a recent report from the Ponemon Institute indicates that the average dwell time is 191 days.

In an ideal world there would no dwell time at all, and threats would be identified before they can penetrate business’ defenses. To achieve this for your organization, it is no longer possible just to run reactive cyber security. It is essential that should invest in a proactive approach – that’s why you need to start threat hunting.

Seeking anomalous activity

Threat hunting is the practice of actively seeking out dangers to cyber security by detecting and eliminating new and emerging threats that are able to evade preventative controls such as firewalls and antivirus software.

It consists of actively looking for anomalous activity that has not been identified by existing tools and involves thorough, on-going analysis of data sources such as network traffic and server logs as well as web and email filter traffic.

Businesses that embrace threat hunting are likely to significantly reduce the dwell time of attacks, identify advanced threats that could otherwise be missed, and enhance security controls and processes. Effective threat hunting requires not only the right tools, but an advanced understanding of the latest tactics and techniques used by criminals. So, what do you need to get started? …more

GUEST ESSAY: Top cybersecurity developments that can be expected to fully play out in 2019

By Ofer Amitai

From a certain perspective, 2018 hasn’t been as dramatic a cybersecurity year as 2017, in that we haven’t seen as many global pandemics like WannaCry.

Related: WannaCry signals worse things to come.

Still, Ransomware, zero-day exploits, and phishing attacks, were among the biggest threats facing IT security teams this year. 2018 has not been a dull year as far as breaches. The cycle of exploit to discovery to weaponization has become shorter, and unfortunately, it has become more difficult to protect the enterprise network and the various devices connected to it.

In 2017, roughly 63% of organizations experienced an attempted ransomware attack, with 22% reporting these incidents occurred on a weekly basis. We expect to wind up with close statistics for 2018.

Here are a few trends I expect will dominate cyber security in 2019.

Security and Privacy Merge

Despite the fact that everyone is still trying to understand the new privacy landscape and perhaps because they haven’t fully grasped the new realities, everyone is paying attention. Perhaps it is our ever increasing focus on privacy in general and GDPR specifically.

Perhaps it is because more organizations will be working long hours to embrace the compliance measures that are needed to protect privacy that we won’t see a major lawsuit against a company. All we know is that we have seen an increase in companies seeking NAC solutions to keep up with all the new compliance regulations and it is very satisfying to hear that sigh of relief, when a company has implemented their solution. …more

GUEST ESSAY: The true cost of complacency, when it comes to protecting data, content

By John Safa

Facebook was lucky when the Information Commissioner’s Office (ICO)—the UK’s independent authority set up to uphold information rights in the public interest—hit the U.S. social media company with a £500,000 fine.

This penalty was in connection with Facebook harvesting user data, over the course of seven years — between 2007 and 2014. This user data became part of the now infamous Cambridge Analytica scandal.

Facebook was very lucky, indeed, that its misdeeds happened before May 25, 2018. On that date, the EU General Data Protection Regulation (GDPR) came into force.

If its violation had happened after that, the fine could have been up to £17 million or 4 percent of global turnover. Yet, even with the prospect of stupendously steep fines hanging over the heads, insecure enterprises still don’t grasp the true cost of data privacy complacency.

According to research by one law firm, pre-GDPR regulatory fines had almost doubled, on average, between 2017 and 2018, up from £73,191 to £146,412. Those figures pale when stacked against the potential bottom line impact that now exists. …more

GUEST ESSAY: Why corporate culture plays such a pivotal role in deterring data breaches

By Max Emelianov

Picture two castles. The first is impeccably built – state of the art, with impenetrable walls, a deep moat, and so many defenses that attacking it is akin to suicide.

The second one isn’t quite as well-made. The walls are reasonably strong, but there are clear structural weaknesses. And while it does have a moat, that moat is easily forded.

Related podcast: The case for ‘zero-trust’ security

Obviously, on paper the castle with better defenses is the one that survives a siege. But what really makes the difference here is the people manning it. See, the soldiers in the second castle are unquestionably loyal to their king. While in the first castle, there is a turncoat in the ranks.

As you’ve probably surmised, the castles are meant to represent a business’s security infrastructure.

The soldiers are a business’s employees. Unless the two are in alignment with one another – unless your employees care about keeping corporate data safe and understand what’s required to do so – your business is not secure.

People power

It doesn’t matter how strong your walls are. It doesn’t matter how much money you invest into point solutions and hardened architecture. It doesn’t matter how many people you hire to man your IT department. …more

GUEST ESSAY: ‘Tis the season — to take proactive measures to improve data governance

By Todd Feinman

The holiday season is upon us and the bright lights and greenery aren’t the only indicators that we’ve reached December.

Sadly, data breaches often occur at this time of year. Recently we’ve seen major news stories about breaches at Starwood Hotels and Quora.

Related podcast: The need to lock down unstructured data

Last year, at this time, it was announced that there was a significant privacy leak at eBay affecting many customers. And, it was just before the holidays in 2013 that Target announced the infamous breach impacting more than a hundred million people.

The list goes on, and with each incident everyone is always asking the same question — Could this have been prevented and how? Every large brand is acutely aware that securing its data is of foremost importance in today’s world, and that by protecting data you are protecting the brand’s equity.  That should be obvious after what we see in the news, however, it’s not always so straightforward.

According to the Poneman analyst report, The Importance of DLP in Cybersecurity Defense, many organizations still believe, “it’s probably not going to happen to me.” The first step toward fortifying one of the company’s most valuable assets — customer or employee data — is to get to know the data better. …more
