Fostering Cyber Security in a Hybrid Work Model: Is Your Organization Ready?

Incontestably, the last 15-18 months have bought a pivotal shift in the lives of people as well as organisations globally. Businesses are brainstorming and coming up with new initiatives to sustain business continuity, preserve employees’ well-being and safeguard their reputation, along with critical assets and information against sophisticated cyber-attacks. Accordingly, some companies are planning to adopt or move to a Hybrid Work Environment to resume operations in a post-pandemic atmosphere.

Comprehending The Hybrid Work Model

Hybrid work arrangement is a remarkable shift from the conventional work model. It can have multiple variations. For instance, businesses might provide their employees with the flexibility to work remotely and from the office. Employees have the freedom to choose where they are most productive, and even they can prefer a blend of both.

This model is perceiving a boom in popularity due to several reasons, including an increase in productivity, improved work-life balance and job satisfaction, deep visibility into an employee’s performance and reduced costs for businesses. The time in the office can be now utilized for collaborative initiatives and in-person meetings.

Are We Underrating the Risks of the Hybrid Work Model?

The Hybrid Model has undoubtedly gained multiple benefits for organizations. But, concurrently, incorporating this new way of working has opened the doors of new cyber risks to businesses. They are facing different security challenges as the workforce is constantly switching between remote and office locations. While working from outside the office, they often follow sloppy safety measures like using public networks where they may get affected by malware or trojans.

Let’s walk through some critical security challenges of a Hybrid Work environment.

  • First Line of Defence – Humans

Humans are generally considered the weakest link in the security chain of any organization. Lack of proper cyber security awareness among them may become the major cause of a cyber-attack. Threat actors use techniques like social engineering, phishing, smishing and vishing to trick victims and gain access to their systems. Since the remote workforce is more exposed to these threats, the risk is considerably high.

  • Mounting Reliance on Cloud

The growing adoption of cloud technology over the last two years has gained the attention of cybercriminals. Despite having multiple benefits, the cloud has its own set of susceptibilities that could raise concerns about data protection, security and compliance. Business-critical information can be compromised in different ways. It may get damaged, corrupted, inappropriately accessed or simply lost, resulting in a catastrophe for an organization.

  • Shifting Perimeters

One of the biggest challenges of this new way of working for organizations is the fact that people will be required to access data beyond the perimeters of the company. In such circumstances, businesses will be required to pay attention to security concerns around how the data is being accessed, transmitted and stored. Investment in the right tool and technology will become a pivotal factor in the race against threat actors.

  • Attacks Targeting Vulnerabilities in VPNs & Windows RDP

Cybercriminals always look to target and exploit the vulnerabilities in the unpatched VPNs and misconfigured RDP servers. It will be vital for organizations to ensure that patching is done on time and regularly. They must evaluate their existing authentication systems and implement multi-factor authentication to add an additional layer of security for remote access.

  • Usage of Personal Devices

Along with the challenges of the moving perimeter, there are plenty of organizations that are facing issues due to BYOD culture. Since the workforce can use their own personal devices to access corporate assets, companies ended up loosening the security and focus on how the data is moving outside their boundaries. The biggest concern of such policies is to ensure that data is not leaking out of the environment.

How to Protect Your Hybrid Environment?

Businesses moving to the new hybrid model of working must execute security strategies that should safeguard their critical resources (including data, systems, servers, etc.), remote workforce and operational continuity from the rising wave of cyber threats.

An organization must consider the below-mentioned cyber security practices to create a successful hybrid work environment and mitigate the risk of cyber attacks.

  • Installation of anti-malware/virus software
  • Conducting cyber security awareness sessions
  • Implementation of Virtual Private Networks (VPNs)
  • Execution of multi-factor authentication
  • Patching security loopholes by installing regular updates
  • Practising strong passwords
  • Maintaining regular data backups
  • Implementation of an Advanced Web Application Firewall (WAF)

Towards The End

Establishing a positive and secured hybrid work environment entails the utilization of the right tools and technology to enable the workforce to access all the important resources at the required time to finish their tasks. Enterprises of all sizes can reduce the risk of a hybrid work model by employing a proactive cyber security approach that must involve necessary measures like regular security audits, implementation of Zero Trust, application of anti-malware software, data backups, etc.

Evolution of Cyber Security in the Post-Covid World: Proactive Approach is a Must

The concept of a “Proactive Approach to Cyber Security” is not new but seldom applied since most organizations had and still have a reactive cyber security strategy in place. As a result of which a majority of businesses suffered long-term losses, and some got drained. Evolving cybercrime, including new attack techniques and advanced tools, is shifting the momentum from reactive to proactive cyber defence.

While talking about recent times, COVID-19 outbreak has fueled the growing spike of cyber attacks across the globe. It has given cyber criminals a lot of opportunities to break down and evade our efforts to safeguard our critical digital assets. They leveraged the moment when organizations had to switch from the traditional approach to the new normal. As much as we are bringing innovation and automation into the digital ecosystem, it is adding another entry point for the threat actors to get hold of the victims’ systems and sensitive data.

Proactive Approach in Perimeter-less World

These days, businesses of all sizes (across different verticals) are mindful that cyber security matters as the shift to remote work is here to stay for long. As more the workforce will work beyond the perimeters of the enterprises, the attack surface of organizations will continue to increase. It will also become a daunting challenge to manage the security of the remote assets. Additionally, the increased application of IoT devices also made it difficult for organizations to manage security. Since these devices are made keeping user experience in mind, it is slightly easier to shatter their defence and get access to the system.

As attacks are becoming, even more, smarter and persistent than ever, adopting a Proactive Approach can be the key to get back control over what’s happening within your corporate network. It is a holistic approach to security that focuses on prevention rather than repairing.

The Proactive approach helps organizations to understand their security infrastructure and underlying systems, applications, networks, data, etc. It involves recognizing and fixing security risks before attackers exploit them and damage the reputation of the company.

Contents of a Proactive Cyber Security Strategy

Proactive cyber security strategy involves different methods and techniques that helps in preventing cyber attacks from happening. It includes (but not limited to):

  • Complete visibility of the security posture
  • Red Teaming & Blue Teaming Exercises
  • Proactive Monitoring of Networks and Endpoints
  • Security Awareness Training
  • Advanced Threat Intelligence
  • Periodic Vulnerability Assessments
  • Build Own Security Operations Center

Reap Benefits of a Proactive Approach

Do not wait for a cyber security incident to happen. Take action before attackers reach you and penetrate your defence. Below are the few advantages of implementing a Proactive Cyber Security Approach:

  • Actively prevents cyber attacks and data breaches
  • Boosts confidence of the customers, partners and third-party vendors
  • Provides time to build effective response strategy for complex threats
  • Catch the adversaries by using advanced threat intelligence
  • Mitigate the risks from malicious insiders
  • Strengthen compliance with industry regulations and data protection laws

Towards The End

Being proactive will offer more control over an environment and provide comprehensive visibility of your organization’s IT assets. Adding proactive strategy to cyber defence can really increase the level of protection and resilience against Advanced Persistent Threats (APTs), ransomware, malware, phishing and more related cyber attacks. The ultimate goal of this strategy is to let people –

“Focus on Preparing, Rather than Repairing.”

Managing Cyber Risks in Energy Sector: A Key Challenge

A recent cyber-attack on the US popular fuel pipeline operator demonstrated that why cybersecurity professionals worldwide see ransomware as one of the biggest threats to public safety. This attack is a clear indication of how the frequency and complexity of cyber threats targeting critical infrastructures have amplified over the years. Earlier this year, anonymous hackers somehow got access to the Florida water treatment facility and altered the sodium hydroxide levels to an extremely hazardous level.

In short, these incidents showed that essential services providers are on the list of threat actors and more vulnerable than ever before. It would not be an overstatement if the growing digitization of such infrastructures is considered as one of the reasons behind the spike in cyber-attacks. Undoubtedly, modern digital elements have significantly optimized the effectiveness of energy systems. But, at the same time, the chances of cyber intrusions have increased manifold. Other reasons may include (but not limited to) legacy infrastructure and systems, nation-backed actors for cyber espionage, high returns for cybercriminals, etc. In a recent survey done by World Economic Forum, 49% of respondents reported that cybersecurity failures are one of the medium-term risks facing the world.

Security Practices to Keep Critical Energy Infrastructures More Secure

In order to mitigate potential risks and harness the full benefits of digitalization, organizations must work in accordance with the governments and redefine the security strategies of the critical infrastructures. New practices should be embedded to shape up the overall security.

Following are a few suggestions for critical organizations to ramp up their cybersecurity without hampering business productivity:

  • Build a strong cybersecurity governance model

Organizations must adopt a forward-looking approach, instead of following reactive measures, to ensure security. Establishing a robust cybersecurity governance model containing a comprehensive risk management approach, along with a complete set of management tools and a security awareness program, will assist organizations to address all of their cybersecurity needs. 

  • Increase the visibility of third-party risks (safeguard the supply chain)

Marginal flaws in third-party software or products may turn into critical vulnerabilities for your organization. Threat actors may target third-party vendors to penetrate your organization’s security infrastructure. Third-party risks may involve (but not limited to) operational risks, compliance risks, reputational risks, etc. Organizations must check and ensure that their supply chain vendors meet all necessary cybersecurity requirements. They should implement an effective defence plan that includes risk assessments and appropriate mitigations.

  • Test your response plans

Creating an incident response plan is key to mitigate the potential damage. But to check their effectiveness, organizations must conduct regular drills and exercises to look for security loopholes (if exists). Perform a detailed vulnerability scan to determine the potential systems likely to be targeted by the cybercriminals. Such practices help in identifying exactly what your critical weaknesses might be and what actions various personnel will need to take in the event of a breach.

  • Collaborate with other stakeholders in the industry

Industry-wide collaborations can help organizations to address the increasing cyber risks to a great extent. Sharing information regarding attackers and their tactics can reduce the potential risks and help other companies to prepare in advance to thwart them. Conveying data also builds trust among organizations, and sustaining such practices foster confidence in optimizing cybersecurity.

  • Educate Workforce

Companies must educate employees about the most common methods through which different malware, trojans or viruses are delivered. They must conduct security awareness programs, wherein the workforce should be made aware of the common phishing attacks and the steps to look and inspect anything that appears suspicious. Employees must be trained to counter any adverse situation to avoid any data breach or other malicious intrusion.

Towards The End

The cyber threat landscape for power generation companies has been rapidly evolving and expanding with more frequent cyber-attacks leveraging complex and sophisticated malware and other tools. One of the most challenging vulnerabilities to address is the supply chain risk. Organizations must prepare themselves in advance to address the ongoing wave of attacks. They should remain mindful of what is happening in cyber security and persist to work in order to reduce the potential vulnerabilities in their critical systems.
