Cybersecurity in 2021: Plan Now To Confront Future Challenges

As 2021 has come close to our doors, it is an opportune time for companies to relook and set an effective strategy to navigate through the cybersecurity challenges in the coming year. All the C-level executives must brainstorm to effectively deal with concerns such as meeting regulatory compliance, keeping pace with emerging trends and technologies, preparing a strong incident response and remediation plan, and creating policies to securely manage critical data throughout its lifespan. All these tasks need to be accomplished while keeping in mind the security of sensitive digital assets, which becomes even more difficult when we all are in the midst of a pandemic. It is important for organizations to set their goals and priorities regarding the cybersecurity challenges right from the beginning of the new year.

Let’s discover some promising ways that can help in mitigating cybersecurity risks and strengthening the IT infrastructure in 2021.

  • Focus on Cloud Security

Cloud migration has increased incredibly in 2020. As per a report from the Synergy Research Group, global spending on cloud infrastructure services increased 33% in Q2 2020 over the same period in 2019 to $30 billion. During this pandemic, the velocity of creating digital-native business applications and services has greatly enhanced as enterprises are preparing themselves for survival in the post-pandemic period.

In 2021, organizations must look for misconfigurations and human errors, implement strong practices for container security, and meet compliance with industry regulations such as PCI, HIPAA, GDPR, etc. Companies should adopt and execute such a cloud security strategy that accelerates significant workplace transitions, to incorporate constantly increasing remote workforce. They can also prioritize Privileged Access Management (PAM) & Identity Access Management (IAM) to provide the least privilege access to the confidential data. Also, investment in Zero Trust Policy and Micro-segmentation will be a good option for cloud security.

  • Look for Insider Threats

Insider threats are one of the biggest drivers of the security risks faced by organizations as an insider has all the necessary rights required to assess the company’s critical assets. Identification and detection of malicious insider activities is a daunting task as companies often lack the ability to detect such unusual activities within their premises. According to a report by Forrester, it is expected that internal incidents will be accounted for 33% of data breaches in 2021.

Organizations should consider insider threat defence in order to prevent such incidents while being cautious not to degrade employees’ privacy, company’s culture and standards for labour practices. They can follow the below-mentioned security procedures to mitigate insider threats:

    • Conduct regular risk assessments
    • Create and document security policies such as account management, user monitoring and password management policies
    • Invest in security software like endpoint protection, intrusion detection and prevention and traffic monitoring
    • Strengthen the network security
  • Add Multi-factor Authentication (MFA)

Throughout 2020, data breaches remained at the top of the headlines across the globe. Malicious activists have gained incredible success in stealing sensitive business data with the help of stolen usernames and passwords, which are now easily available on underground marketplaces like Dark Web. Threat actors take advantage of the fact that most of the users still do not select strong and unique passwords for their accounts.

MFA reduces the risk by providing additional security methods, apart from username and password, such as One-Time Passwords (OTPs) that you often receive via emails & SMS. It is expected to be a crucial factor in protecting a user’s identity and preventing unauthorised account accesses. As per a recent report from MarketWatch, the global Multi-Factor Authentication (MFA) market size is expected to reach USD 32110 million by the end of 2026, with a CAGR of 19.6% during the forecast period (2021-2026).

  • Keep an Eye on Human Vulnerability

In 2021, enterprises must keep a sharp eye on the security of their workforce against the growing and evolving social engineering and phishing attacks. CISOs and other security leaders need to focus on and improve the casual attitude of employees towards cybersecurity in order to reduce the occurrences of data breaches and cybersecurity attacks.

It will be vital for organizations to look into cybersecurity education and training of their workforce, particularly when remote work is being followed globally. Employees should be made aware of the basic practices such as the creation of a strong password and double-check the URLs (embedded in emails) before clicking on them.

  • Review Data Security & Privacy Policies

In 2021, the data privacy landscape will remain in the spotlight. With the increasing focus on compliance with industry regulations, organizations will be looking forward to the security and privacy of data more seriously than ever. Classifying data as public, private and confidential is not sufficient enough to avert data breaches. Companies often provide employees with access to data that they do not need, and hence they are more likely to face a data security incident.

Strong data access controls and policies should be considered as one of the top priorities in 2021 in order to ensure the security of critical business data. Solutions, like email security, can be viewed and implemented to keep a check on what data is being transferred or received to/from outside the organizational perimeter. Companies must regularly review policies to track how their critical information is being stored and update authorizations on a regular basis.

Cybersecurity Preparedness – Lessons We Learnt In 2020

To call 2020 a year filled with unprecedented challenges would not be an overstatement. Right from the eruption of COVID-19 pandemic to a comprehensive list of disruptive cyber-attacks, 2020 has engendered enormous concerns to enterprise cybersecurity teams. While these cyber-attacks have caused terrible damage to many organizations globally, they have also presented several key lessons for cybersecurity and information security professionals moving forward. By taking into consideration these lessons, enterprises can augment and strengthen their security posture against the rising wave of cyber threats.

Now as we move towards a new calendar year, let us have a look at some critical areas that need to be looked after cautiously.

Data Security is Crucial

As per a recent report from Risk Based Security, the number of records exposed through the end of September 2020 has increased to 36 billion. Two breaches in Q3 leaked more than 1 billion records and four breaches exposed over 100 million records, which together accounted for approximately 8 billion exposed records.

Therefore, companies must look to protect their sensitive data in all forms i.e. at rest, in motion and in use throughout its lifespan. They should ensure data integrity, security and consistency by heeding advanced security controls like robust encryption policies that can help in reducing the impact, to some extent, if data is exfiltrated or stolen. They can establish a data governance program to manage the flow of critical information across the organization. This program may include (but not limited to) the below points:

  • Assigning roles and responsibilities for managing and monitoring the consistent and effective management of the data assets
  • Identifying who can take what actions, with what data, under what circumstances
  • Establishing different security levels for different categories of data like highly sensitive, moderately sensitive and publicly available information

Check For Vulnerabilities

Threat actors discover and exploit vulnerabilities in order to penetrate corporate networks and infect critical resources with malware, Trojans and worms. Organizations must seek to identify and address the existing security gaps through vulnerability assessments that should be followed as a continuous practice performed at regular intervals. Such assessments have become more important than ever as employees have started coming back to their offices after a long break of remote working. Safety practices such as patching vulnerabilities and reviewing security settings will play a key role in mitigating cybersecurity incidents.

Cybersecurity Awareness & Training for Employees

As humans are more likely to create errors in comparison with digital assets, threat actors primarily target them using popular techniques like Social Engineering and Phishing. So far, we have witnessed several instances where cybercriminals leveraged human vulnerability to cause damage and gain huge profits.

Did you know that around 22% of breaches in 2019 involved phishing? (Source: Verizon DBIR 2020)

In 2020, the phishing attacks have continued to explode. As per the APWG’s Trend Report Q3 2020, around 199,133 unique phishing websites were detected in September. The report revealed that Saas & webmail sites were the most targeted industry sectors in Q3 2020. The most noticeable thing is that 80% of phishing sites were protected by the HTTPS encryption protocol.   

Therefore, enterprises must mitigate the probability of human errors through regular training and awareness sessions. Improving awareness will not only enhance cyber hygiene and reduce cyber risks, but also help in cultivating cybersecurity culture within organizations.

Look For Ransomware

Ransomware has been the most prevalent cyber-attack faced by organizations across the world in 2020. As per a recent report by SonicWall, ransomware attacks globally have increased by 40% to reach 199.7 million in the Q3 2020. Enterprises need to remain careful and can follow the below-mentioned practices to ensure their safety:

  • Encourage employees to avoid clicking on the unknown URLs
  • Create data backup
  • Avoid disclosing personal information to unknown calls, texts or emails
  • Promote usage of anti-virus/anti-malware software
  • Conduct security awareness sessions

Be Ready with Incident Response Plan

Companies should follow a proactive approach while preparing themselves to defend cybersecurity incidents. This approach can help organizations to protect their critical data, brand reputation, customers’ trust from getting impacted by malicious activities. An Incident Response plan may include (but not limited to) some key phases including preparing a plan to prevent and respond to events, identify incidents and its severity, containment of the incident before it causes damage, addressing the root cause of the incident and restoration of systems to normal operation.

Towards the End…

Cybersecurity is not an overnight process. It is an ongoing practice that takes time and continuous efforts. This COVID-19 crisis has taught us the reason behind why we are at risk. And that is, we are not enough prepared. We often wait for things to happen and then react accordingly. To stay safe and secure, organizations need to follow a proactive approach and invest in their security infrastructure to prevent themselves from falling short to evolving, complex cyber threats.

Vulnerability Assessment: Increasingly Becoming Top Priority for C-Suit in The New Normal

Conducting an assessment to look out for vulnerabilities existing within the networks, applications or infrastructure has always been an ideal approach to safeguard your organization against evolving and complex cyber threats. And, doing so on a regular basis takes an organization far ahead of the reach of cybercriminals.

But, during these uncertain times when businesses have adapted to a remote working model, the attack surface has exploded to a large scale. After which, Vulnerability Assessment (VA) has now surfaced as the core requirement of the CISOs, CIOs, COOs and other C-level executives. The reason behind the expansion of the attack surface and growing demand for security assessment includes:

  • Introduction of Personal Devices: Most employees were not provided with company-issued laptops or computers to continue work from home. Consequently, they were using their own devices to access corporate resources and data that may have vulnerabilities or already been compromised. Also, they have made a huge dependency on web conferencing & collaboration tools like Zoom, Microsoft Team Meeting, Google Meet, etc. for daily operations. Throughout this global crisis, threat actors have leveraged such platforms to deceive people and compromise their devices.
  • Migration to Cloud: Owing to the current pandemic, organizations have promptly moved to the cloud to accommodate remote workforce requirements. But this swift movement has also opened them to multiple risks including configuration errors, vulnerabilities within the applications, security oversight issues, etc. As per the Cloud Threat Landscape Report 2020, any unauthorized access to cloud assets can result in losses of more than $50000 in less than one hour. Also, over one billion records were stolen in 2019 due to misconfigured cloud servers.   
  • Insecure Home Networks: Home networks often lack sufficient security measures that are required for a secured connection with corporate resources. For instance, it does not include intrusion prevention systems, advanced firewalls (say WAFs), etc. This may allow cybercriminals to enter into and get access to critical corporate data and applications. As per a report from BitSight, it was found that home networks are 3.5 times more expected as compared to office networks to be infected by malware. Threats like Mirai malware and Trickbot were observed 20 and 3.75 times, respectively, more frequently on home networks in comparison with corporate networks.

How Vulnerability Assessment Helps

As the new normal has begun, businesses are recognizing the need for a proactive approach to detect and remediate the security flaws (if any) to prevent threat actors from causing havoc and stealing sensitive business-critical data. The VA provides a clear picture of the effectiveness of the security controls in place. It enables organizations to fill the security gap in their security posture before getting exposed by the cybercriminals. An effective VA can yield several benefits including:

  • Find known security vulnerabilities before attackers exploit them
  • Discover all the critical assets present on the network, including vulnerabilities associated with each asset
  • List of required future upgrades
  • Define the level of risk
  • Prepare a well-defined response plan

Outsource Vulnerability Assessment Services

Typically, it is often seen that organizations prefer to have their in-house vulnerability assessment team. An in-house team has its business advantages like it has a better understanding of the systems being assessed, and availability as per the company’s schedule or requirement. But due to the lack of skilled resources, it is somewhat difficult to find the right talent and create your own VA team. Alternatively, businesses can outsource security teams to conduct VA in their environment. It saves time and efforts that can be further utilized in other business functions. It can also help CISOs and CIOs to reduce dependency on internal resources, improve prioritization of human assets, meet compliance with different industry regulations, etc.  

How Market is Shaping

As per a report from MarketsandMarkets,  the global Security and Vulnerability Management market is predicted to increase from USD 12.5 billion in 2020 to USD 15.5 billion by 2025, with a Compound Annual Growth Rate (CAGR) of 4.5%. The contributing factors include growing cyber awareness among developing economies, soaring mandates for adhering to regulatory compliances across organizations in different verticals, growing volume of cyberattacks such as phishing, ransomware, DDoS and malware. According to an estimate by Cybersecurity Ventures, the global annual cost of cybercrimes will reach USD 6 trillion by 2021.


Rather than a quinquennial review process, Vulnerability Assessment should be viewed as a continuous process performed after regular short intervals. An in-depth understanding of the potential security risks within the security posture of an organization can aid C-level executives and their security teams to effectively manage business operations in the new normal while reducing the risks of being compromised. Conducting assessments, along with the implementation of appropriate security solutions like Zero Trust and Privileged Access Management will expand the security capabilities of businesses and help them to stay on top of the vulnerabilities.
