BH Consulting in the media: supply chain security still a concern

The Huawei controversy has raised fundamental questions around supply chain security, Brian Honan has told Infosecurity Magazine. In a video interview recorded at Infosecurity Europe 2019 conference in London, BH Consulting’s CEO said the issue of technology containing alleged backdoors to enable spying has led to “interesting conversations” in the security community.

The question boils down to whether it’s possible to build secure systems if there’s no trust in the technology platform they’re built upon, Brian said. “Unless we actually build something ourselves from absolute scratch, we are relying on third parties, and how much trust can we give to those third parties? So the bigger issue becomes: how you secure your supply chain?”

For security professionals, securing their company’s supply chain needs a more rigorous due diligence process than asking vendors whether they have antivirus software on their PCs. It’s about “asking the right questions into the right levels, and digging deep into the technology, depending on what your requirements are,” Brian said.

Huawei to the danger zone

Noting the accusations that Huawei technology has security bugs, Brian said that the same is true of products from many other places including the US, UK or Europe. “There’s no such thing as 100% secure systems. Take the Intel chips that we have in all our servers: they have security bugs in them,” he said.

Emphasising that he wasn’t trying to defend Huawei, Brian said: “A lot of what we’re reading in the press and the media, there’s nothing to substantiate the claims behind it.” The larger question about whether any bugs are accidental, or deliberately placed backdoors that allow Government-level spying, is “outside the remit of our industry,” he said.

The chain

Even if a security professional decided not to use a certain brand of equipment in their network, there’s a question of what happens when their information travels elsewhere within their company’s external supply chain, or through its internet service provider. Instead, infosec professionals should focus on protecting information at rest or in transit, since the early internet engineers designed it to share information, not keep it secret. “We have been trying to build security on top of a very unsafe foundation. We need to look at ways of how we keep our data safe, no matter where it goes or how far it travels,” Brian said.

As for what’s next in security, Brian said regulations will stay at the forefront over the next year. “GDPR isn’t over. GDPR is the evolution of data protection laws that we had already… the regulations are still being enforced. We still have to continue looking after GDPR.”  Some of the earliest court cases relating to GDPR are due to conclude soon, with potentially large fines for offenders. He also said Brexit is “the elephant in the room”, given how it could affect the way that European companies deal with UK businesses, and vice versa.

Toys in the attic

The ePrivacy Regulation (ePR) will have a huge say in how companies embed cookies on their websites and how they communicate and market to customers. Regulations like the EU Cybersecurity Act look set to impose rules on IoT or ‘smart’ devices. Their security – or lack of it – has long been a thorny issue. Brian recently commented on this issue in an article for the Irish Times about smart toys and we’ve also blogged about it before on Security Watch.

Summing up the likely short-term developments in security, Brian said: “A lot of things in the next 12-24 months are going to have a big impact on our industry, and it’s where the regulators are going to play catch-up on the technology. It’s going to be interesting to see how those two worlds collide.” You can watch the 15-minute video here (free, but sign-in required).

Regulate

Also during Infosecurity Europe, Brian moderated a debate on dealing with complex regulations while ensuring privacy, security and compliance. It featured with data protection and security practitioners from the Bank of England, Penguin Random House UK, News UK and the UK Information Commissioner’s Office. Bank Info Security has a good writeup of some of the talking points. Its report noted that Brian focused the discussion on the broader regulatory landscape, including the updated EU ePrivacy Directive, while panellists and audience questions kept returning to GDPR.

The article noted how the panelists broadly agreed that regulations, including GDPR, helped to improve their organisation’s security posture. It quoted Titta Tajwe, CISO of News UK, who said: “With the EU GDPR, it really helped for executives to understand what needs to happen to protect the data of your customers. So it did allow the CISOs to get the budget they needed to do the work they’d already been asking for, for a long, long time.”

Security roundup: March 2019

We round up interesting research and reporting about security and privacy from around the web. This month: ransomware repercussions, reporting cybercrime, vulnerability volume, everyone’s noticing privacy, and feeling GDPR’s impact.

Ransom vs ruin

Hypothetical question: how long would your business hold out before paying to make a ransomware infection go away? For Apex Human Capital Management, a US payroll software company with hundreds of customers, it was less than three days. Apex confirmed the incident, but didn’t say how much it paid or reveal which strain of ransomware was involved.

Interestingly, the story suggests that the decision to pay was a consensus between the company and two external security firms. This could be because the ransomware also encrypted data at Apex’s newly minted external disaster recovery site. Most security experts strongly advise against paying extortionists to remove ransomware. With that in mind, here’s our guide to preventing ransomware. We also recommend visiting NoMoreRansom.org, which has information about infections and free decryption tools.

Bonus extra salutary security lesson: while we’re on the subject of backup failure, a “catastrophic” attack wiped the primary and backup systems of the secure email provider VFE Systems. Effectively, the lack of backup put the company out of business. As Brian Honan noted in the SANS newsletter, this case shows the impact of badly designed disaster recovery procedures.

Ready to report

If you’ve had a genuine security incident – neat segue alert! – you’ll probably need to report it to someone. That entity might be your local CERT (computer emergency response team), to a regulator, or even law enforcement. (It’s called cybercrime for a reason, after all). Security researcher Bart Blaze has developed a template for reporting a cybercrime incident which you might find useful. It’s free to download at Peerlyst (sign-in required).

By definition, a security incident will involve someone deliberately or accidentally taking advantage of a gap in an organisation’s defences. Help Net Security recently carried an op-ed arguing that it’s worth accepting that your network will be infiltrated or compromised. The key to recovering faster involves a shift in mindset and strategy from focusing on prevention to resilience. You can read the piece here. At BH Consulting, we’re big believers in the concept of resilience in security. We’ve blogged about it several times over the past year, including posts like this.

In incident response and in many aspects of security, communication will play a key role. So another helpful resource is this primer on communicating security subjects with non-experts, courtesy of SANS’ Lenny Zeltser. It takes a “plain English” approach to the subject and includes other links to help security professionals improve their messaging. Similarly, this post from Raconteur looks at language as the key to improving collaboration between a CISO and the board.

Old flaws in not-so-new bottles

More than 80 per cent of enterprise IT systems have at least one flaw listed on the Common Vulnerabilities and Exposures (CVE) list. One in five systems have more than ten such unpatched vulnerabilities. Those are some of the headline findings in the 2019 Vulnerability Statistics Report from Irish security company Edgescan.

Edgescan concluded that the average window of exposure for critical web application vulnerabilities is 69 days. Per the report, an average enterprise takes around 69 days to patch a critical vulnerability in its applications and 65 days to patch the same in its infrastructure layers. High-risk and medium-risk vulnerabilities in enterprise applications take up to 83 days and 74 days respectively to patch.

SC Magazine’s take was that many of the problems in the report come from companies lacking full visibility of all their IT assets. The full Edgescan report has even more data and conclusions and is free to download here.

From a shrug to a shun

Privacy practitioners take note: consumer attitudes to security breaches appear to be shifting at last. PCI Pal, a payment security company, found that 62 per cent of Americans and 44 per cent of Britons claim they will stop spending with a brand for several months following a hack or breach. The reputational hit from a security incident could be greater than the cost of repair. In a related story, security journalist Zack Whittaker has taken issue with the hollow promise of websites everywhere. You know the one: “We take your privacy seriously.”

If you notice this notice…

Notifications of data breaches have increased since GDPR came into force. The European Commission has revealed that companies made more than 41,000 data breach notifications in the six-month period since May 25. Individuals or organisations made more than 95,000 complaints, mostly relating to telemarketing, promotional emails and video surveillance. Help Net Security has a good writeup of the findings here.

It was a similar story in Ireland, where the Data Protection Commission saw a 70 per cent increase in reported valid data security breaches, and a 56 per cent increase in public complaints compared to 2017. The summary data is here and the full 104-page report is free to download.

Meanwhile, Brave, the privacy-focused browser developer, argues that GDPR doesn’t make doing business harder for a small company. “In fact, if purpose limitation is enforced, GDPR levels the playing field versus large digital players,” said chief policy officer Johnny Ryan.

Interesting footnote: a US insurance company, Coalition, has begun offering GDPR-specific coverage. Dark Reading’s quotes a lawyer who said insurance might be effective for risk transference but it’s untested. Much will depend on the policy’s wording, the lawyer said.

Games people play: testing cybersecurity plans with table-top exercises

If a picture is worth a thousand words, and video is worth many multiples more, what value is an interactive experience that plants you firmly in the hot seat during a major security incident? Reading about cyberattacks or data breaches is useful, but it can’t replicate the visceral feeling of a table-top exercise. Variously called war-gaming scenarios or simulated attacks, they can be a valuable way of helping boards and senior managers understand the full implications of cyber threats. More importantly, they can shed light on gaps where the business can improve its incident response procedure.

These exercises are designed to be immersive. They might start with a scenario like a board meeting, or a company orientation day. All participants will get a role to play; for the purpose of the session, they might be designated as a head of HR, finance, legal, or IT. As the scenario starts to unfold, a message arrives. The press has been enquiring about a major data breach or a ransomware attack on the company.

Muscles tighten, a wave of nausea passes over the stomach. The fight-or-flight instinct starts to take hold. Your role might say manager, but you don’t feel like you’re in control.

What happens next?

That will depend on how much preparation your business has done for a possible cybersecurity threat. Some companies won’t have anything approaching a plan, so the reaction looks and feels like panic stations. At various points during this exercise, the facilitator might introduce new alerts or information for the group to react to. For example, that could be negative commentary on social media, or a fall in the company stock price.

The exercise should prompt plenty of questions for the participants. What exactly is going on? How do we find out what’s happened? How is this affecting operations? Who’s taking charge? What do we tell staff, or the public, or the media?

A growing sense of helplessness can be a powerful spur to make rapid changes to the current cybersecurity incident response plan (assuming there is one).

Other organisations may already have a series of steps for what to do in the event of an incident or breach. In these cases, the table-top exercise is about testing the viability of those plans. You can be prepared, but do the steps on paper work in practice? Or as Mike Tyson memorably put it, “everybody has a plan until they get punched in the mouth”.

The exercise can show the value of having a playbook that documents all procedures to carry out: “if X happens, then do Y”. This will also shed light on missing steps, such as contact numbers for key company executives, an external security consultant, regulators, law enforcement, or media.

Fail to prepare, prepare to fail

When it comes to developing or refining an incident response plan, the devil is in the detail, says David Prendergast, senior cybersecurity consultant at BH Consulting. Here are some useful questions to ask:

  • If your policy says: ‘contact the regulator’, ask which one(s)
  • Who is the specific point of contact at the regulators office?
  • Does the organisation have the email address or phone numbers for that person?
  • Who in your company or agency is authorised to talk to the regulator?
  • What information are they likely to need to have that conversation?
  • Do you have pre-prepared scripts or statements for when things might go wrong (for customers, stakeholders, staff, and media (including social media channels)?

It might also force the company into making certain decisions about resources. Are there enough internal staff to carry out an investigation? Is that the most appropriate use for those employees, or is it better to focus their efforts on recovering IT systems?

That’s the value in table-top exercises: they afford the time to practice when it’s calm and you can absorb the lessons. There are plenty of examples of companies that handled similar situations spectacularly badly in full public view. (We won’t name names, but the list includes anyone who uttered the words “sophisticated attack” before an investigation even started.)

By the (play)book

It’s more helpful to learn from positive examples of companies that showed leadership in the face of a serious incident. That can be as simple as a statement of business priorities while an organisation copes with the fallout. In 2017, as Maersk reeled from a ransomware infection, CEO Soren Skou gave frontline staff in 130 countries clear instructions. As the Financial Times reported, the message was unequivocal even as the company was forced into shutting down IT systems. “Do what you think is right to serve the customer – don’t wait for the HQ, we’ll accept the cost.”

Some larger companies will run an exercise just for themselves, but some organisations run joint war-gaming scenarios with industry peers. Earlier this month, financial institutions and trade associations from around Europe carried out a simulated ransomware attack.

According to FinExtra, the scenario took the form of an on-site technical and hands-on-keyboard experience. There were 14 participants at CISO and CIO level, along with many more observers from other companies in the financial sector. The aim of the event was to encourage collaboration and information sharing with other teams and organisations to improve collective defences against cyber threats.

Whether it’s a war-gaming exercise or a table-top event, the goal is the same: to be ready for the worst ahead of time, and knowing what steps are available to you when bad things happen for real.

Security roundup: February 2019

We round up interesting research and reporting about security and privacy from around the web. This month: security as a global business risk, insured vs protected, a 12-step programme, subject access requests made real, French fine for Google, and an imperfect getaway.

Risks getting riskier

Some top ten lists are not the kind you want to appear on. Data theft and cyber attacks both featured in the World Economic Forum’s Global Risks Report 2019. Only threats relating to extreme weather, climate change and natural disasters ranked above both security risks.

The report is based on a survey which asked 1,000 decision makers to rate global risks by likelihood over a 10-year horizon. As ZDNet reports, 82 per cent of those surveyed believe there’s an increased risk of cyberattacks leading to the theft of money and data. Some 80 per cent believe there’s a greater risk of cyberattacks disrupting operations.

The report also refers to the increased risk of cyberattacks against critical infrastructure, along with concerns about identity theft and decreasing privacy. The WEF’s overview includes a video of a panel discussing the risks, and the report itself is free to download.

Insuring against cyber attacks

Thinking of buying cyber risk insurance in the near future? The legal spat between Mondelez and Zurich might give pause to reconsider. The US food company sued its insurer for refusing to pay a $100 million claim for ransomware damages. NotPetya left Mondelez with 1,700 unusable servers and 24,000 permanently broken laptops. Zurich called this “a hostile or warlike action” by a government or foreign power which therefore excluded it from cover.

As InfoSecurity’s story suggests, Zurich might have been on safer ground by invoking a gross negligence clause instead, since Mondelez got hit not once but twice. And where does this leave victims? “Just because you have car insurance does not mean you won’t have a car crash. Just because you have cyber insurance does not mean you won’t have a breach,” said Brian Honan.

Lesley Carhart of Dragos Security said the case would have implications for cyber insurance sales and where CISOs spend money. “Not only is Zurich’s claim apparently that nation state adversaries can’t be insured against, but it adds the ever tenuous question of attribution to insurance claims,” she wrote.

The 12 steps to better cybersecurity

Somewhat under the radar, but no less welcome for that, Ireland’s National Cyber Security Centre has published guidance on cybersecurity for Irish businesses. It’s a high-level document that takes the form of a 12-step guide. It’s written in non-technical language, clearly intended for a wide audience. The steps include tips like getting senior management support for a cybersecurity strategy. The full report is free to download from here. We’ve taken a deep dive into the contents and you can read our thoughts here.

Fight for your right to part…ake of your data

GDPR obliges companies to cough up the personal data they hold about us on request, but what does that mean in practice? Journalist Jon Porter exercised his right to a subject access request with Apple, Amazon, Facebook, and Google. Just under 138GB of raw data later, he discovered that little of the information was in a format he could easily understand. If some of the world’s biggest tech companies are struggling with this challenge, what does that say for everyone else? It’s a fascinating story, available here.

Google grapples French fine

And speaking of all things GDPR-related, France’s data protection regulator CNIL has hit Google with a €50 million fine for violating the regulation. The CNIL claims Google didn’t make its data collection policies transparent enough and didn’t obtain sufficient, specific consent for personalising ads.

As Brian Honan wrote in the SANS Institute newsletter: “While the €50 million fine is the item grabbing the headlines, the key issue here is the finding by CNIL of the unlawfulness of Google’s approach to gathering people’s personal data. This will have bigger implications for Google, and many other organisations, in how they ensure they legally gather and use people’s personal data in line with the GDPR.”

You can run, but you can’t hide

Here’s a cautionary tale about the dangers of oversharing personal data on smart devices. UK police collared a hitman for an unsolved murder after data from his GPS watch linked him to scouting expeditions of the crime scene. Runners World covered the story and the Liverpool Echo published CCTV footage of an alleged recon trip near the victim’s home.

It’s an extreme example maybe, but the story shows how heavy our digital footprints can be (running shoes or not). Social media sharing can also be a security risk for a company’s remote workers. Trend Micro’s Bob McArdle outlined this very subject in his excellent Irisscon 2018 presentation. Social engineering expert Lisa Forte tweeted that she can gather intel about target companies from what their employees post online.

Ireland’s cybersecurity watchdog publishes new guidance for businesses

Ireland’s National Cyber Security Centre has published guidance on cybersecurity for Irish businesses. It’s a welcome addition to the roster of material available to help organisations to develop or refine their security strategy. The team at BH Consulting has picked out key points from the guide, and added some more context and analysis.

The report’s non-technical language show that it’s clearly intended for a wide audience. In a move that’s doubtless designed to help spread the message widely, the document presents its 12 steps in three formats: as an infographic (see below), on a single page of text, and then as longer descriptions for each step.

Preparing for ‘when’, not ‘if’

Reading through the guide, it’s striking how it starts from the premise that attacks are already going on. As the introduction makes clear:

“Cyberattacks make headlines on a daily basis. It’s no longer a question of if your company will be breached, or even when, it’s likely to have happened already. The real question is whether you will know and are you prepared?”

This language echoes the Central Bank of Ireland’s 2016 guidance which warned about this risk in similarly stark terms. “Firms should assume that they will be subject to a successful cyber-attack or business interruption”, the bank said.

A resilient approach to security

The NCSC’s high-level document aims to make businesses more resilient to security incidents. That’s an approach we can all get behind. In several blogs from last year, we looked at this very issue through a business and risk lens. In one post, Brian Honan suggested a four-step process to improving resilience:

  • Identify key systems and services for your business
  • Look at the key risks and threats to those services
  • Based on that risk analysis, identify the key areas to address such as single points of failure, inter-reliance of systems and interdependency of systems
  • Engineer ways to mitigate the impact of any potential failure, either through cybercrime or other means.

Looking back, it’s interesting how many of the themes overlap with the NCSC guidance. As we noted at the time, this is about thinking of security as a business problem, not a technological one.

Obviously, businesses still need to put effort into preventing certain types of attacks and security incidents. But it’s arguably even more important to put measures in place to keep the business running no matter what. Resilience takes many forms: after attackers defaced the website for the Luas, the tram service kept running but it took nearly a month for the site to reopen.

The Irish National Cyber Security Centre’s 12-step activity plan.

Rather than advising a ‘big bang’ culture change to embrace security, the guide suggests using the steps as an activity plan to undertake over a 12-month period. The report spends a lot of time at a high level before getting into specific actions to take, or naming particular tools to use. In fact, the first five steps don’t look in-depth at technology. Instead, they’re about orienting a business to think about security in a systematic way.

Steps 1-4

The guide is free to download from here. Step one covers governance and organisation: that means getting senior management support for a cybersecurity plan. Next comes the step of identifying the assets that matter most. (This is a broad list, covering everything from business goals, products, and services through to people, processes technology and data infrastructure underpinning them.) The steps then follow through to identifying threats and defining risk appetite.

Steps 5-6

Interestingly, the document advises focusing on education and awareness before it covers basic technical protections. These include secure configuration, patch management, firewalls, anti-malware, removable media controls, remote access controls, and encryption.

(For organisations that prefer to skip directly to this step, the guide offers a ‘minimum baseline’ of essentials protection that includes boundary firewalls, secure configuration, patch management, malware protection, encryption and access controls.)

Steps 7-11

Step seven involves setting up the ability to monitor for suspicious activity. In another nod to the broad mix of businesses this advice applies to, the guide notes that security monitoring can range from a basic alerting system through to a more sophisticated security operations centre.

The subsequent steps cover putting in place post-incident measures. They include having a formal cyber incident management team, establishing recovery plans, and implementing extra protections to supplement the basic controls. Step 11 advises running a mocked-up exercise to test how the management would react to a security breach.

Step 12 and context

The lifecycle finishes on creating an ongoing cyber risk management lifecycle. This twelfth and final action needs to be part of ‘business as usual’, the NCSC advises. The guide strikes a fair balance between useful advice and appealing to the broadest possible audience. The ‘practical considerations’ page, which isn’t part of the 12 steps, lays out the message in simple terms. A company’s level of security will vary depending on lots of factors like the potential threats that affect it the most, the level of risk it’s prepared to accept, and the amount of budgetary and people resources it can afford to allocate.

Valerie Lyons, chief operations officer with BH Consulting, says the guide provides a really good grouping of the various areas in which to approach cyber resilience. However, she feels some areas need clarification. For example, using months as a measure could be misleading. “Identifying what matters most can take a day in a small accounting office, and take a year in a large hospital. If we take May for instance, ‘focus on education and awareness’, this should in fact be a throughout-the-year activity engrained throughout every step. However, the steps by virtue of their month-by-month presentation allow a plan to be developed,” Valerie says.

Beyond the guide: extra steps

It’s arguable that the step of creating a cyber risk management lifecycle, which the guide puts in December, should in fact be in January. “We should determine up front what the regulatory landscape looks like and the resources required to achieve it,” Valerie says.

The guide would also benefit from clear definitions of cyber resilience, and what cyber risk means to the organisation. Instead of only focusing on the threat of external attacks, businesses should weigh up the risk from their own users’ accidental or deliberate actions.

As well as the practical steps in the guide, Valerie says organisations can also run tests, red teaming exercises, and table-top scenarios to test their security. Lastly, she recommends that businesses should manage cyber risk like all other risks, and it should be led by the chief risk officer, or risk unit.

The Irish NCSC report is a welcome addition to a growing crop of business-focused security advice from trusted, independent sources. There’s a wealth of free material for businesses of all sizes that are only starting to get the security message. ENISA, the European Union agency for network and information security, regularly publishes advice which you can find here. Similarly, The UK National Cyber Security Centre also publishes excellent, easy-to-read advice. Think of it as a form of public immunisation. The more organisations are vaccinated against the most common security risks, the safer we’ll all be.
