Managing cloud cyber security

As cloud computing continues to reshape the business world, the need to ensure the security of this complex new environment is more important than ever. This comes with its own significant challenges. Increased cloud adoption is bringing increased exposure to cyber threats, leaving businesses vulnerable to ever-evolving forms of attack.

With cyber threats showing no sign of slowing down, organizations cannot afford any gaps in their cloud infrastructure. Fortunately, there are concrete actions every company can take to strengthen their security stance. To find out more, Scott Nicholson, Co-CEO of Bridewell, shared his thoughts.

Why is cloud cybersecurity so crucial?

Traditional cybersecurity was built around on-premises infrastructure to manage on-premises threats. But the landscape looks very different today. The rise of cloud computing has made the digital world more interconnected and accessible than ever before, as data and applications have moved outside the traditional perimeter. This change has rendered most legacy network security controls obsolete, so it is essential that cybersecurity methods evolve to keep pace with accelerated cloud adoption.

At the same time, these increasingly complex IT and networking infrastructures are bringing new opportunities for cyber criminals, due to the expanded attack surface. We need only look at recent news headlines to recognize the threats. The Russian-backed hackers behind the Sunburst cyber attack managed to exploit cloud vulnerabilities to pilfer emails and files from over 100 companies around the world. We are also seeing cloud-based systems, services and data being targeted by ransomcloud – attacks that take advantage of weaknesses or legitimate functionality in cloud resources to deploy malware, encrypt data, and extort money from businesses.

To manage such a complex web of risks, companies need to review their own cloud security posture today and put in place measures to boost visibility, cyber maturity and resilience.

How can companies tackle the problem of skills gaps when it comes to cloud security?

There’s no denying that the skills gap is a growing challenge. Unfortunately, a lot of organizations started their cloud transformation journey on the back foot, implementing remote access tech without the skills needed to secure and manage cloud environments on an ongoing basis. This has led to a skills, transformation, and burnout cycle: IT teams are being asked to do more with less people to support transformation, heightening the risks of human error, data breaches, and the cycle getting underway again.

But there are ways that companies can break through the cloud security skills gap. Education is key to mitigating threats in the cloud, so all IT, security, and end users need to be fully informed and trained on a range of basic cyber hygiene practices and how these translate into cloud environments, covering areas such as controls testing, configuration hardening, network segmentation and incident response capabilities in the cloud.

Also, organizations shouldn’t be afraid to expand their talent pool by recruiting people from other backgrounds. Too many organizations focus purely on cyber talent and could be missing out on many great candidates with transferable skills. Here at Bridewell, we have taken on a lot of IT engineers and trained them up to be penetration testers and these are now some of our best people.

Companies also have the option to partner with a trusted managed security services provider with expertise in cloud security solutions. Outsourcing addresses the cyber security skills gap by providing ongoing expertise and support, which is very difficult to achieve in-house.

What challenges are preventing organizations from gaining the visibility needed to detect and respond to threats in the cloud?

There are a number of reasons why organizations may struggle to gain a detailed view of all activity in the cloud. In today’s diverse digital landscape, it’s common to see the convergence of traditional enterprise IT infrastructure with public cloud in a hybrid deployment. Businesses are also now integrating their operations with multiple cloud providers, which adds an extra layer of complexity. This means that some traditional security operations centers (SOCs) are having to juggle around 40 different tools to cover the cloud and every other possible vulnerability, each of which needs to be configured, supported, and monitored 24/7. This is a huge ask, and resources will be stretched further as OT and IT continues to converge.

Organizations can improve their cloud visibility today by having a multi-cloud security strategy and aiming to move towards having a full Extended Detection & Response (XDR) capability to help detect and respond to security threats in a more holistic and efficient manner.

How can companies better balance operational uptime and security requirements?

Of course, every organization wants to have effective security in place but without hindering and negatively impacting business operations. This is absolutely critical for some Operational Technology (OT), where it is performing critical functions that have a health and safety consequence.

Context in these scenarios is king. Understanding what risks are faced, the threat actors and the various methods in which a cyber attack could occur will enable informed decisions to be made regarding the application of cyber security controls and risk mitigation activity. Threat modelling is a very good methodology to structure and deliver this type of approach, which should include security professionals, engineering teams and any other key stakeholders.

There are also security technologies that provide non-intrusive network based detection capabilities to aide visibility, which is a great starting point for security improvements. Having a development environment or being able to replicate segments of an environment to test the application of security controls, will all aide understanding and decision making.

What does a proactive cyber security posture look like, and how can organizations achieve it?

Organizations with a proactive cyber security posture take the initiative to drive long-lasting security improvements from within, rather than waiting for the next big breach to happen. This involves moving away from traditional reactive security techniques – which focus simply on detection and notification of attacks – towards a more intelligent stance that gives a clear, holistic view of cyber security across IT, OT, cloud, and end user devices. As both cloud adoption and cloud security risks continue to grow, this proactive approach is critical to business continuity.

To build a proactive stance, businesses need to understand the threats they’re likely to face – past, present, and future. Threat intelligence is vital in enabling IT teams to quickly detect and respond to active threats in the cloud. With the right strategy, based on threat intelligence linked to managed detection and response (MDR) and supported by ethical hacking techniques to test defenses, companies can ensure they are fully armed in the face of evolving cloud-based threats.

Organizations that have a proactive cyber security posture also understand that attacks are inevitable, they focus on how quickly they can identify, detect and respond to those attacks in addition to compartmentalizing any successful attacks and having confidence in their ability to resume systems in a timely manner if negatively impacted.

Adobe Acrobat and Reader have some serious security flaws, so patch now

Adobe has issued a urgent warning to users of its Acrobat and Acrobat Reader PDF editors following the discovery of a zero-day vulnerability of critical severity.

The software company has released a security update for Windows and macOS users, urging them to apply the patch as soon as possible in order to reduce the risk of an attack.

In a statement, the firm said: “Adobe is aware that CVE-2023-26369 has been exploited in the wild in limited attacks targeting Adobe Acrobat and Reader.”

Adobe Acrobat and Reader patch

Details about the vulnerability remain scarce given the fresh nature of the discovery, however the software maker did confirm that: “Successful exploitation could lead to arbitrary code execution.”

Acrobat DC and Acrobat Reader DC versions 23.003.20284 and earlier have been confirmed to be affected, as have 2020 versions of both software running build 20.005.30516 and earlier for macOS and 20.005.30514 and earlier for Windows.

Adobe’s latest software updates for its PDF programs, which became available on September 12, address a series of security issues. They also introduce some feature changes and enhancements, including the ability to reposition quick tools, new undo and redo options in the top menu bar, drag-and-drop support for combining files, and more.

The San Jose-based company also issued further updates across its range of products, including Adobe Connect and Adobe Experience Manager software, which allowed attackers to gain arbitrary code execution on unpatched devices.

The discovery of vulnerabilities in Adobe’s software is not ideal, but nor is it alarming. Companies release security fixes for their software on a regular basis in order to iron out vulnerabilities and protect users, and the fact that the company responded with speed is admirable.

Adobe or not, anybody using any digital service should keep an eye on software and firmware updates that become available, installing them as soon as possible.

Fortifying your business with two-factor authentication and two-step verification

The digital realm is teeming with risks that can compromise business data. Thankfully, a variety of tools and technologies are available for your company to fortify its cybersecurity. Two-factor authentication (2FA) and two-step verification (2SV) are among the most effective methods for bolstering your defenses against attackers.

2FA and 2SV are often used interchangeably, but they are, in fact, two distinct approaches to security. Let’s take a look at the differences between them and explore how they can benefit your business.

Two-factor authentication

2FA is a security measure that requires users to provide two different types of credentials in order to log into their accounts. Typically, the first factor consists of something that the user knows, such as a password. The second factor could be something like a one-time passcode sent via text message or email or a biometric identifier, such as a fingerprint.

With 2FA enabled on your business accounts, cybercriminals will have a harder time gaining access to these. Even if they somehow manage to obtain the first factor (e.g., by guessing your password), they still won’t be able to log in without the second piece of information, which only you can have.

Two-step verification

2SV is similar to 2FA in that it requires two pieces of information to gain access to an account. However, the difference between the two lies in the number of authentication steps involved. As the name suggests, 2SV requires two authentication steps: one where the user provides their first factor (e.g., a password) and another where they provide additional information that proves they are who they say they are.

For example, with 2SV enabled on your business accounts, users may be asked to provide a second form of authentication when they attempt to log in from an unfamiliar device or IP address. This could be in the form of another password, a one-time passcode generated by an authentication app on their phone, or some other type of verification.

Benefits of 2FA and 2SV for businesses

Enabling 2FA and/or 2SV on your business accounts can provide a variety of benefits, including:

  • Improved security – By adding an extra layer of authentication, you can reduce the risk of unauthorized access to your accounts.
  • Enhanced compliance – By using advanced authentication, such as 2FA and 2SV, you can ensure that your business is meeting industry and government standards for data security.
  • Reduced costs – Fewer unauthorized access attempts means fewer chances of fraud and data theft, which can lead to significant cost savings over time.

Which is best for your business?

The decision of whether to use 2FA or 2SV depends on a number of factors, such as the size and complexity of your business, the type of data you are storing, and the level of security you require.

For example, if your business is storing sensitive data, such as customer credit card information, then a multifactor authentication system that includes both 2FA and 2SV may be the most appropriate choice. On the other hand, if you are simply looking to add an extra layer of protection to your email accounts, then a 2FA system may be all that is needed.

Ultimately, the best authentication solution for your business will depend on its individual needs and requirements. It is always a good idea to consult with an experienced security professional to ensure that you are making the right decision.
