In a world where we spend more and more time online, cybersecurity is indispensable.
In the course of our +8 years of existence, we at SmartLinks have had our fair share of online or cyber attacks, either directly on us or on our clients.
Especially since 2020 (Covid) it has become very clear that cyberattacks are increasing at an exponential rate and it is essential to protect personal and business data, guaranteeing the security and continuity of digital activities, which are essential in the day-to-day life of our society.
Cyberspace is an increasingly hostile environment and cyberattacks are increasing in frequency and complexity, with a significant impact on companies such as:
- The loss of confidential data, whether in the form of customer information, employees or intellectual property;
- The interruption of operations, which leads to loss of revenue and productivity;
- Reputational damage, which jeopardises customers‘ and partners’ trust in brands.
In Portugal, the number of computer-related crimes grew by 6 per cent compared to the previous year in 2021, and phishing and other types of online scams continue to be the most reported types of crime.
Some recent news in Portugal that should serve as a warning to companies:
Social engineering and scam attacks, such as the ‘Hello Dad, Hello Mum’ WhatsApp scam, which in Portugal alone had thousands of victims and millions of euros in losses.
A few weeks ago, Gondomar Town Hall and Alcanena Town Hall were the targets of cyber attacks and Boeing was also in the news.
At the beginning of the year, Banco CTT customers were victims of online fraud. A series of fraudulent web pages were accessed by customers who then suffered a phishing attack.
In 2022, the telecoms company Vodafone was the target of a cyber attack that led to the interruption of the television and internet service for some customers.
This news shows that any company, regardless of its size or sector of activity, can be the target of a cyber attack.
This reality makes it URGENT for individuals and companies to implement cybersecurity measures to protect their systems, data and people (customers, employees and partners).
What are some cybersecurity measures that companies can implement?
Implementing effective cybersecurity measures is crucial to safeguarding vital information and maintaining brands’ own reputations.
The five most common strategies that companies can employ to strengthen digital security in the business environment are:
Implementing an information security policy;
Training employees in cyber security;
Informing customers about safe practices for using their digital resources;
Investing in cyber security solutions;
Continuously monitoring systems and data to identify and respond to security incidents.
Cybersecurity is everyone’s responsibility: companies, employees and public authorities.
But even before defining the online security strategies to be applied, you have to start at the bottom:
Defining and implementing relevant cybersecurity tests to assess potential risks.
What are Cybersecurity Tests?
Cybersecurity tests are procedures designed to assess and strengthen the security of information systems.
The main cyber threats in Portugal (and worldwide) can be grouped into the 10 most common types:
Malware attacks;
Ransomware attacks;
DDoS (Distributed Denial of Service) attacks;
Spam attacks;
Password Vulnerability Attacks;
Phishing attacks;
Man-in-the-Middle attacks;
SQL injection;
Corporate Account Takeover;
Brute Force attacks.
Security tests fall into 2 main categories, Penetration Testing and Vulnerability Assessment, each with specific objectives and methodologies.
Penetration Testing or Pentesting
Penetration testing simulates cyber attacks in order to identify vulnerabilities. It uses various methodologies and tools to carry out controlled attacks, assessing the response of systems.
Vulnerability Assessment
Unlike Penetration Testing, Vulnerability Assessment focuses on identifying and classifying vulnerabilities in systems, without necessarily simulating an attack. It involves the use of specific scanning and diagnostic tools.
The Main Stages of Cybersecurity Testing
A cybersecurity test involves several stages, from planning to analysing the results. Each stage is fundamental to guaranteeing the test’s effectiveness.
Planning cybersecurity tests
The planning phase involves defining the objectives of the test, choosing the appropriate tools and outlining the test strategy. Here’s a breakdown of what to do in this phase:
Defining Objectives: Initially, it is essential to determine the objectives of the test. These can range from identifying vulnerabilities, evaluating the effectiveness of current security measures, to testing the ability to respond to security incidents.
Delimiting the Scope of the Test: It is necessary to clearly define the scope of the test, specifying the systems, networks and applications to be evaluated. It is important to establish precise limits to avoid negative impacts on systems that are not the subject of the test.
Methodology selection: Depending on the objectives, the most appropriate approach is chosen, which can include penetration tests, vulnerability assessments or phishing simulations. Each of these methodologies uses specific techniques and tools.
Resource planning: The necessary resources are identified, such as a specialised team, testing tools and budget. It is vital to ensure that the team has the necessary skills and tools. If necessary, hire a company specialising in cybersecurity.
Communication with Stakeholders: It is essential to involve and inform all stakeholders, such as management, the IT and security teams, and possibly the organisation’s employees. This ensures that everyone is aware of the test and its consequences.
Drawing up a Timetable: A detailed timetable is established for carrying out the test, taking into account the minimum impact on the organisation’s daily operations.
Preparing a Contingency Plan: Strategies are prepared to deal with any problems that may arise during the test, such as service interruptions or critical security findings.
Execution of cybersecurity tests
The execution of the tests must be closely monitored to ensure that everything goes according to plan and that the results are faithful to the reality of the tested system.
Here are all the stages of this phase:
Preparation: Before starting the tests, it is necessary to confirm that all the tools and resources are ready and functional. In addition, it is important to ensure that the test start communications have been made to all interested parties.
Test Execution According to Plan: Tests are carried out following the established plan. This can include penetration tests, where testers try to exploit vulnerabilities to gain access to systems or data, simulated phishing attacks to assess employee response, social engineering, among many others.
Monitoring and logging: During execution, it is crucial to carefully monitor all activities and keep detailed records. This includes recording any vulnerabilities discovered, the methods used to exploit them, and any impact observed on systems.
Constant Communication: Maintaining constant communication with the IT and security teams is essential to respond to any unexpected incidents and to ensure that the test is not causing unwanted interruptions.
Real-Time Impact Assessment: If critical vulnerabilities are identified or if the test is having a significant impact on systems, it may be necessary to make real-time adjustments to both the test method and the scope itself.
Compliance with Ethical and Legal Rules: It is essential that all tests are conducted ethically and in compliance with applicable laws, especially with regard to data protection and privacy.
End of Testing: Once testing is complete, it is important to carry out a final check to ensure that all systems are returned to their normal state and that any changes made during testing are reversed.
Analysing the results
After execution, it is crucial to analyse the data collected, interpreting it to generate detailed reports and practical recommendations.
Here are its phases:
Data Compilation: Initially, all the information and data collected during the execution of the tests is grouped together. This includes records of the vulnerabilities detected, the methods used to exploit them and any other relevant incidents.
Detailed Analysis: This is followed by a detailed analysis. The severity of each vulnerability, its potential exploitation by attackers and the impact each one could have on the organisation are assessed. This analysis is fundamental to understanding the risk associated with each weakness found.Correlation with External Contexts: In addition to the internal analysis, it is important to correlate the results with external information, such as known vulnerabilities and trends in cyber attacks. This correlation helps to contextualise the vulnerabilities identified in the global cybersecurity landscape.
Reporting: The results of the analysis are compiled into detailed reports, which should include a listing of the vulnerabilities found and practical recommendations for mitigating them.
Prioritisation of Measures to be Taken: Based on the analysis, priority actions are determined. The most serious vulnerabilities or those with the greatest potential impact should be addressed with the greatest urgency.
Discussion with Stakeholders: The results and recommendations are then discussed with the stakeholders, including the management, IT and security teams. This dialogue is essential to ensure a clear understanding of the risks and the necessary measures.
Development of an Action Plan: Based on the results of the analysis and discussions with stakeholders, a detailed action plan is developed to address the vulnerabilities identified and strengthen overall security.
Feedback for Continuous Improvement: Finally, the insights gained from analysing the results can be used to improve the organisation’s cybersecurity processes, including improving future security tests.
Post-Test Learning and Improvement
Every test is an opportunity for learning and continuous improvement of security systems. See the phases of this stage:
Review of Test Results: After the tests have been completed and the results analysed, the first stage is a detailed review of these results. This review provides an in-depth understanding of the vulnerabilities identified and the flaws in the security processes.
Identification of Lessons Learned: The aim is to identify lessons learnt from the tests, which includes understanding how and why the vulnerabilities existed, and what types of attacks could exploit them. This understanding helps prevent similar problems in the future.
Development of Improvement Plan: Based on the lessons learnt, an improvement plan is developed that addresses the vulnerabilities and gaps identified. This plan can include software updates, changes to security policies, employee training, among other measures.
Implementation of Improvements: The identified improvements are then implemented. This step can require significant effort, depending on the nature and scope of the changes required.
Training and Awareness: A critical part of the learning phase is training and making employees aware of best security practices. This is essential to avoid human error that can lead to security breaches.
Continuous Monitoring: Once improvements have been implemented, it is important to carry out continuous monitoring to ensure that the changes are effective and to identify new vulnerabilities that may arise.
Continuous Feedback and Adjustment: The learning and improvement phase is a continuous process. Based on the feedback obtained through continuous monitoring, the security plan should be regularly adjusted to meet new challenges and threats.
Documentation and Knowledge Sharing: Finally, it is important to document the entire process and share the knowledge gained within the organisation. This helps to ensure that everyone involved understands the changes made and the importance of cyber security.
Challenges and Limitations of Cybersecurity Testing
Although essential, cybersecurity testing faces several challenges, including technical limitations and even (sometimes) some organisational resistance.
Some challenges (especially for internal teams) can be the need to keep up to date with new threats:
Trying to keep up with the constant evolution of cyber threats is like trying to run on a treadmill that accelerates randomly and sharply!
Attackers are always inventing new techniques, which makes it difficult for security tests and procedures to cover all possible angles.
Another challenge is resource limitations:
Carrying out comprehensive testing can be as affordable for an SME as a Ferrari for the average citizen.
It requires financial resources, sophisticated tools and qualified specialists, which not all organisations can afford.
The eternal ‘false’ positives and negatives:
Sometimes you identify problems that don’t exist (false positives) or fail to detect real problems (false negatives).
It’s a bit like looking for a needle in a haystack.
The impact of testing on the company’s operational systems should not be overlooked:
Carrying out tests in production environments can be as risky as juggling knives. There is always the risk of interrupting critical operations or causing other unforeseen problems and incurring profit shortfalls or direct losses.
Legal and ethical compliance can be a grey area:
Navigating cybersecurity laws and regulations can be as complex as understanding Swedish furniture assembly instructions. Testing must be carried out ethically and in compliance with privacy and data protection laws.
Limited scope:
Cybersecurity testing is often restricted to certain systems or applications. This is like putting a high-security lock on the front door while leaving the kitchen window open. Vulnerabilities outside the scope of the test remain undetected.
The famous post-test complacency:
Passing a cybersecurity test can give a false sense of security. It is crucial to maintain a posture of constant vigilance, even after positive results.
Some points are worth highlighting further, so we want to emphasise the ethical and legal issues involved in cybersecurity testing:
Ethical Aspects
Carrying out cybersecurity tests ethically and responsibly involves respecting users’ privacy and avoiding unnecessary harm.
Some key ethical principles include:
Consent: Users must be informed about the tests and give their prior consent.
Loyalty: Tests must be carried out loyally and honestly.
Restraint: Unnecessary harm must be avoided during testing.
Transparency: Test results must be shared transparently.
Legal aspects
Legal aspects
Tests must comply with the laws in force and in Portugal, one of the biggest concerns is data protection legislation, which requires this type of test to respect users’ privacy.
The companies responsible for the tests can be held liable for any damage caused to users. It is therefore essential that tests are carried out carefully, responsibly and in a structured manner.
What is the future of cybersecurity testing?
We don’t know what the future will bring, but one thing is certain: we will continue to see technological developments and emerging challenges.
As the digital landscape continues to expand and evolve, so too will cybersecurity testing methods have to adapt to face increasingly sophisticated threats.
Some of the resources / developments to consider and which in some cases are already in use:
Automation and Artificial Intelligence (AI): One of the most significant advances is the integration of automation and artificial intelligence into cybersecurity testing. AI, in particular, will make it possible to carry out faster and more efficient tests, capable of continuously learning and adapting to new threat patterns.
IoT and Mobile Security Testing: With the rise of the Internet of Things (IoT) and the widespread use of mobile devices, cybersecurity testing will focus more on these areas, addressing vulnerabilities specific to these devices and ecosystems.
Integration with Software Development: Cyber security will be increasingly integrated into the software development lifecycle. Practices such as DevSecOps, which incorporates security into all phases of software development, will become more prevalent.
Regulatory Compliance and Legislation: As legislation around data protection and privacy becomes stricter in various parts of the world, cybersecurity testing will have to adapt to ensure ongoing compliance with laws and regulations.
Proactive and Adaptive Approaches: The future of cybersecurity testing will be marked by a more proactive and adaptive approach. Instead of reacting to incidents, testing will seek to anticipate and mitigate potential threats before they materialise.
Cybersecurity Training and Awareness: The human element is and will always be the focus, with more investment in cybersecurity training and awareness, both for professionals in the field and for end users.
Global Co-operation and Information Sharing: International co-operation and information sharing on cyber threats will be increasingly important to combat co-ordinated and sophisticated attacks.
The future of cybersecurity testing promises to be a dynamic, constantly evolving field, essential for protecting our systems and data in an increasingly digitised world.

Real-Time Impact Assessment:
If critical vulnerabilities are identified or if the test is having a significant impact on systems, it may be necessary to make real-time adjustments to both the test method and the scope itself.
Compliance with Ethical and Legal Rules: It is essential that all tests are conducted ethically and in compliance with applicable laws, especially with regard to data protection and privacy.
End of Testing: Once testing is complete, it is important to carry out a final check to ensure that all systems are returned to their normal state and that any changes made during testing are reversed.
Analysing the results
After execution, it is crucial to analyse the data collected, interpreting it to generate detailed reports and practical recommendations.
Here are its phases:
Data Compilation: Initially, all the information and data collected during the execution of the tests is grouped together. This includes records of the vulnerabilities detected, the methods used to exploit them and any other relevant incidents.
Detailed Analysis: This is followed by a detailed analysis. The severity of each vulnerability, its potential exploitation by attackers and the impact each one could have on the organisation are assessed. This analysis is fundamental to understanding the risk associated with each weakness found.Correlation with External Contexts: In addition to the internal analysis, it is important to correlate the results with external information, such as known vulnerabilities and trends in cyber attacks. This correlation helps to contextualise the vulnerabilities identified in the global cybersecurity landscape.
Reporting: The results of the analysis are compiled into detailed reports, which should include a listing of the vulnerabilities found and practical recommendations for mitigating them.
Prioritisation of Measures to be Taken: Based on the analysis, priority actions are determined. The most serious vulnerabilities or those with the greatest potential impact should be addressed with the greatest urgency.
Discussion with Stakeholders: The results and recommendations are then discussed with the stakeholders, including the management, IT and security teams. This dialogue is essential to ensure a clear understanding of the risks and the necessary measures.
Development of an Action Plan: Based on the results of the analysis and discussions with stakeholders, a detailed action plan is developed to address the vulnerabilities identified and strengthen overall security.
Feedback for Continuous Improvement: Finally, the insights gained from analysing the results can be used to improve the organisation’s cybersecurity processes, including improving future security tests.
Post-Test Learning and Improvement
Every test is an opportunity for learning and continuous improvement of security systems. See the phases of this stage:
Review of Test Results: After the tests have been completed and the results analysed, the first stage is a detailed review of these results. This review provides an in-depth understanding of the vulnerabilities identified and the flaws in the security processes.
Identification of Lessons Learned: The aim is to identify lessons learnt from the tests, which includes understanding how and why the vulnerabilities existed, and what types of attacks could exploit them. This understanding helps prevent similar problems in the future.
Development of Improvement Plan: Based on the lessons learnt, an improvement plan is developed that addresses the vulnerabilities and gaps identified. This plan can include software updates, changes to security policies, employee training, among other measures.
Implementation of Improvements: The identified improvements are then implemented. This step can require significant effort, depending on the nature and scope of the changes required.
Training and Awareness: A critical part of the learning phase is training and making employees aware of best security practices. This is essential to avoid human error that can lead to security breaches.
Continuous Monitoring: Once improvements have been implemented, it is important to carry out continuous monitoring to ensure that the changes are effective and to identify new vulnerabilities that may arise.
Continuous Feedback and Adjustment: The learning and improvement phase is a continuous process. Based on the feedback obtained through continuous monitoring, the security plan should be regularly adjusted to meet new challenges and threats.
Documentation and Knowledge Sharing: Finally, it is important to document the entire process and share the knowledge gained within the organisation. This helps to ensure that everyone involved understands the changes made and the importance of cyber security.
Challenges and Limitations of Cybersecurity Testing
Although essential, cybersecurity testing faces several challenges, including technical limitations and even (sometimes) some organisational resistance. Some challenges (especially for internal teams) can be the need to keep up to date with new threats: Trying to keep up with the constant evolution of cyber threats is like trying to run on a treadmill that accelerates randomly and sharply! Attackers are always inventing new techniques, which makes it difficult for security tests and procedures to cover all possible angles. Another challenge is resource limitations: Carrying out comprehensive testing can be as affordable for an SME as a Ferrari for the average citizen. It requires financial resources, sophisticated tools and qualified specialists, which not all organisations can afford. The eternal ‘false’ positives and negatives: Sometimes you identify problems that don’t exist (false positives) or fail to detect real problems (false negatives). It’s a bit like looking for a needle in a haystack. The impact of testing on the company’s operational systems should not be overlooked: Carrying out tests in production environments can be as risky as juggling knives. There is always the risk of interrupting critical operations or causing other unforeseen problems and incurring profit shortfalls or direct losses. Legal and ethical compliance can be a grey area: Navigating cybersecurity laws and regulations can be as complex as understanding Swedish furniture assembly instructions. Testing must be carried out ethically and in compliance with privacy and data protection laws. Limited scope: Cybersecurity testing is often restricted to certain systems or applications. This is like putting a high-security lock on the front door while leaving the kitchen window open. Vulnerabilities outside the scope of the test remain undetected. The famous post-test complacency: Passing a cybersecurity test can give a false sense of security. It is crucial to maintain a posture of constant vigilance, even after positive results. Some points are worth highlighting further, so we want to emphasise the ethical and legal issues involved in cybersecurity testing: Ethical Aspects Carrying out cybersecurity tests ethically and responsibly involves respecting users’ privacy and avoiding unnecessary harm. Some key ethical principles include: Consent: Users must be informed about the tests and give their prior consent. Loyalty: Tests must be carried out loyally and honestly. Restraint: Unnecessary harm must be avoided during testing. Transparency: Test results must be shared transparently. Legal aspects Legal aspects Tests must comply with the laws in force and in Portugal, one of the biggest concerns is data protection legislation, which requires this type of test to respect users’ privacy. The companies responsible for the tests can be held liable for any damage caused to users. It is therefore essential that tests are carried out carefully, responsibly and in a structured manner.What is the future of cybersecurity testing?
We don’t know what the future will bring, but one thing is certain: we will continue to see technological developments and emerging challenges.
As the digital landscape continues to expand and evolve, so too will cybersecurity testing methods have to adapt to face increasingly sophisticated threats.
Some of the resources / developments to consider and which in some cases are already in use:
Automation and Artificial Intelligence (AI): One of the most significant advances is the integration of automation and artificial intelligence into cybersecurity testing. AI, in particular, will make it possible to carry out faster and more efficient tests, capable of continuously learning and adapting to new threat patterns.
IoT and Mobile Security Testing: With the rise of the Internet of Things (IoT) and the widespread use of mobile devices, cybersecurity testing will focus more on these areas, addressing vulnerabilities specific to these devices and ecosystems.
Integration with Software Development: Cyber security will be increasingly integrated into the software development lifecycle. Practices such as DevSecOps, which incorporates security into all phases of software development, will become more prevalent.
Regulatory Compliance and Legislation: As legislation around data protection and privacy becomes stricter in various parts of the world, cybersecurity testing will have to adapt to ensure ongoing compliance with laws and regulations.
Proactive and Adaptive Approaches: The future of cybersecurity testing will be marked by a more proactive and adaptive approach. Instead of reacting to incidents, testing will seek to anticipate and mitigate potential threats before they materialise.
Cybersecurity Training and Awareness: The human element is and will always be the focus, with more investment in cybersecurity training and awareness, both for professionals in the field and for end users.
Global Co-operation and Information Sharing: International co-operation and information sharing on cyber threats will be increasingly important to combat co-ordinated and sophisticated attacks.
The future of cybersecurity testing promises to be a dynamic, constantly evolving field, essential for protecting our systems and data in an increasingly digitised world.
