Authentication vs. Authorization

/in

These two fundamental concepts play a pivotal role in ensuring the integrity and security of digital systems.

While these terms are often used interchangeably, they represent distinct and equally essential aspects in the world of identity and access management (IAM), which safeguards sensitive information and resources .

Executive summary

Authentication confirms that users are who they say they are. Authorization gives those users permission to access a resource.

The relationship between authentication and authorization is symbiotic. Authentication precedes authorization, as it’s imperative to confirm an entity’s identity before permitting or denying access.

 

Details

Authentication: Proving Identity

Authentication is the process of verifying the identity of a user, system, or entity attempting to access a particular resource, system, or network.

It aims to answer the fundamental question: “Who are you?” and “Are you who you say you are?”.

In other words, the purpose of authentication is to ensure that the entity requesting access is indeed who they claim to be.

A successful authentication process provides a digital identity, often represented by a username or user ID, that can be used for subsequent authorization.

For answering these questions, authentication typically relies on one or more factors, categorized as:

  1. Something you know: This factor involves information only the user should know, such as a password, PIN, or passphrase.
  2. Something you have: This includes possession of a physical object like a smart card, token, or mobile device.
  3. Something you are: Also known as biometrics, this factor uses unique physical or behavioral attributes like fingerprints, retinal scans, or voice recognition.

 

Authorization: Granting Permissions

Authorization takes place after a successful authentication.

Authorization is the process of determining what a user, system, or entity can do after they’ve been authenticated.

It answers the question: “What are you allowed to do?”.

To implement this, authorization is typically implemented through access control policies, which dictate which actions a user is allowed to perform, what data they can access, and the extent of their privileges.

Access control decisions can be based on various factors, including user roles, permissions, and the context in which a request is made.

Zero Trust in Cybersecurity: from myth to the guide

/in

Every single day I read news on various portals and on LinkedIn and I encounter a lot of buzz words.

Most of the time I just smile recognizing the marketing b**it, and continue to scroll…

This time, I found an article from the Germany’s Federal Bureau of Information Security (BSI) and it was about Zero Trust (DE). Note, this is summary, meant to be full of buzzwords, not a guide or anything similar.

I have to say that Zero Trust used to be a lot more prominent in the Corona years, between 2020 and 2022 than it is now. This shows also the history on IT Security News and Google Trends.

 

What is Zero Trust?

Zero Trust is a cybersecurity framework designed to address the limitations of traditional perimeter-based security models. Oh, if you didn’t read the article on cybersecurity framework, go there and give it a try.

In the past, companies would rely on firewalls and trust the inside network while treating the outside as a potential threat.

Zero Trust, on the other hand, assumes that threats can originate from both inside and outside the network. It promotes a “never trust, always verify” approach or how we usually say, to be politically correct, “trust is good, but control is better”.

 

Core principles

1. Identity Verification

Before granting access every user, device and application attempting to access network resources must go through a verification process.

2. Limited Access Privileges

Users and systems should only have access to the resources, for their tasks; nothing

3. Micro Segmentation

The network is split into separate sections to limit the spread of threats.

4. Continuous Monitoring

Constantly observing and analyzing network activity, user actions and system well being, in time.

5. Flexible Access Control

Access permissions can adjust dynamically depending on the users actions, device security status and contextual factors.

 

Why Zero Trust is such a popular term

Zero Trust is not exclusive to any industry or company size. It can be implemented by any organization looking to enhance its cybersecurity posture. Whether you’re a business or a multinational corporation Zero Trust can be tailored according to your requirements.

Due to the COVID 19 restrictions, all companies had to increase the reliance on cloud services, implement remote work, and proliferate mobile devices, which resulting in an expanded traditional network perimeter.

This transformation has made organizations more vulnerable to cyberattacks.

To summarize, these are the main reasons why Zero Trust has become so popular:

1. Changing Nature of Cyber Threats

With cyber threats becoming advanced and unpredictable organizations need to take measures to defend against them.

2. Impact of Remote Work

The COVID 19 pandemic has accelerated the adoption of work rendering traditional network perimeters ineffective.

3. Embracing Cloud Services

As businesses shift towards cloud computing, data and applications are no longer limited to, on premises environments.

4. Adherence to Data Privacy Regulations

Compliance with data privacy regulations like GDPR and CCPA necessitates the implementation of data protection measures.

Implementing the Zero Trust framework

There is nothing new here, the same steps apply as to any other cybersecurity framework and ISMS.

I will not go into details about it, just go back and read these articles on ISMS and NIS2.

1. Identify and classify your digital assets

2. Implement strong user authentication methods, verify their identities before granting access

3. Ensure that users and systems have the minimum necessary access permissions.

4. Segment your network into smaller zones to limit lateral movement in case of a breach.

5. Deploy real-time monitoring and analysis tools to track anomalies

6. Implement Adaptive Access Control

7. Encrypt data both in transit and at rest

8. Conduct regular security audits

9. Educate employees about the importance of security

10. Develop an Incident Response Plan

Securing the Secure: The Importance of Secure Software Practices in Security Software Development

/in

In an increasingly interconnected digital world, the importance of secure software cannot be overstated.

Many people think that by using security software all their digital assets become automatically secured.

However, it is crucial to recognize that security software itself is not inherently secure by default.

To ensure the highest level of protection, security software must be designed, developed, and maintained using secure software practices.

This blog post emphasizes how important it is to incorporate secure software development practices within the broader context of the secure software lifecycle for security software.

 

Understanding the Secure Software Lifecycle

The secure software lifecycle encompasses the entire journey of a security software product, from its inception to its retirement.

It consists of multiple stages, such as :

  • Requirements gathering/Analysis
  • Design,
  • Implementation
  • Testing,
  • Deployment
  • Maintenance
  • Retirement

Incorporating secure software practices at each step is essential to fortify the software’s defense against potential vulnerabilities and attacks.

 

Implement Secure Software Development Practices

Implementing secure software practices involves adopting a proactive approach to identify and address security concerns from the outset.

Some fundamental practices include:

a. Threat Modeling:

Conducting a comprehensive analysis of potential threats and vulnerabilities helps developers design robust security measures. By understanding potential risks, developers can prioritize security features and allocate resources accordingly.

b. Secure Coding:

Writing code with a security-first mindset minimizes the likelihood of exploitable vulnerabilities. Adhering to coding standards, utilizing secure coding libraries, and performing regular code reviews and audits contribute to building a solid foundation for secure software.

c. Secure Configuration Management

Properly configuring the security software environment, such as secure network settings, encryption protocols, and access controls, is vital for safeguarding against unauthorized access and data breaches.

d. Regular Security Testing

Rigorous testing, including vulnerability assessments, penetration testing, and code analysis, helps identify and rectify security flaws. It ensures that security software operates as intended and remains resilient against evolving threats.

 

The Bigger Picture: Security in a Connected World

Secure software development practices extend beyond the development of security software alone. They have a broader impact on the overall security ecosystem. The adoption of secure software practices sets a precedent for other software developers, promoting a culture of security awareness and accountability.

Moreover, incorporating secure practices in security software helps foster trust among users and organizations. It instills confidence that the software is diligently designed to protect sensitive information and critical systems. Secure software practices also contribute to regulatory compliance, enabling organizations to meet stringent security standards and safeguard user data.

 

The Vital Importance of Secure Software: Consequences of Security Vulnerabilities for Security Companies

The implications of security vulnerabilities go beyond the immediate risks they pose to users and organizations. For security companies, the consequences of having products with security vulnerabilities can be severe, impacting their reputation, customer trust, and overall business viability.

Here are just a few negative consequences that security companies may face if their products fall prey to security vulnerabilities:

  1. Reputation Damage: Security companies are built on trust and reliability. When a security product is discovered to have vulnerabilities, it erodes customer confidence and tarnishes the company’s reputation. The perception that a security company cannot protect its own software casts doubt on its ability to safeguard sensitive information and defend against external threats. This loss of trust can be challenging to regain, resulting in a significant blow to the company’s credibility and market standing.
  2. Customer Loss and Dissatisfaction: Security vulnerabilities in software can lead to compromised systems, data breaches, and financial losses for users. In such instances, customers are likely to seek alternative security solutions, abandoning the vulnerable product and the company behind it. This loss of customers not only affects the company’s revenue but also demonstrates a lack of customer satisfaction and loyalty. Negative word-of-mouth can spread rapidly, deterring potential customers from considering the security company’s offerings in the future.
  3. Legal and Regulatory Consequences: Security vulnerabilities can have legal and regulatory implications for security companies. Depending on the nature and severity of the vulnerabilities, companies may face legal action from affected parties, resulting in costly litigation and potential financial penalties. Furthermore, security companies operating in regulated industries, such as finance or healthcare, may face compliance violations, leading to fines and reputational damage. Compliance with security standards and industry regulations is critical for security companies to maintain credibility and avoid legal consequences.
  4. Increased Operational Costs: Addressing security vulnerabilities requires significant resources, both in terms of time and finances. Security companies must invest in dedicated teams to investigate, fix, and release patches or updates to address vulnerabilities promptly. Additionally, engaging in incident response, customer support, and post-incident communication efforts adds to the operational costs. Failure to address vulnerabilities in a timely and efficient manner can exacerbate the negative consequences, making the recovery process more challenging and expensive.

 

In an era where security breaches and cyber threats are prevalent, relying solely on the notion that security software is inherently secure is a grave misconception. Secure software practices are indispensable for developing robust and resilient security software. By implementing these practices throughout the software lifecycle, developers can significantly mitigate the risks associated with vulnerabilities and ensure the highest level of protection for users and organizations alike. Embracing secure software practices sets the stage for a safer digital landscape, bolstering trust, and reinforcing security across the entire software development ecosystem. By prioritizing security, security companies can protect their customers, preserve their reputation, and maintain a competitive edge in the ever-evolving landscape of cybersecurity.

The Automotive industry’s inadequate approach towards software (in the cars)

/in

Introduction

The automotive industry has witnessed a paradigm shift with the increasing integration of software in vehicles.

Modern cars are no longer just mechanical devices with a motor, wheels and steering; they are now sophisticated machines having dozens of CPUs (called ECU), entire computers, high speed network to connect them (called CAN-bus) and relying on complex highly distributed software systems.

In my opinion, the industry fails to adapt to this new reality and fully embrace the concept of cars as hardware running software has significant consequences.

This may sound contradictory at first, on one side they have these complex systems, on the other side they fail to adapt to this reality.

In this article, I will explore how the automotive industry is not dealing correctly with this transformation and its potential implications.

 

Limited Focus on Software Development and Updates

Traditionally, the automotive industry has primarily focused on hardware design and manufacturing, treating software as a necessary mean to make the hardware work.

This approach results in a lack of emphasis on software development practices and updates capabilities.

While cars are becoming more connected and dependent on software for various functionalities, manufacturers often overlook the importance of continuous software improvements and security updates.

How often do you update the software of your car? Maybe once a year in the best case, usually once every several years or not at all.

It’s not all bad, but think of how many times does Open SSL get updated in a year. Theoretically you should see an update every few months.

 

Insufficient Over-the-Air (OTA) Update Capabilities

Related to updates, Over-the-Air (OTA) updates have gained prominence in the software industry as an efficient means of delivering software fixes, updates, and new features directly to users.

However, the automotive industry has been slow to adopt OTA capabilities on a widespread scale out of their own will.

Limited OTA functionality not only hampers the ability to address software vulnerabilities promptly but also restricts the potential for delivering new features and enhancements to vehicles post-purchase.

Fortunately, there are many initiatives to solve this and even legislation (UNECE R 155 and R 156) that started to make software updates mandatory for releasing new car types.

 

Slow Adoption of Agile SW Development Processes

Agile software development methodologies have become the norm in the software industry due to their flexibility and iterative nature.

However, the automotive industry lags behind in adopting these practices. And this is politically correct formulated.

The OEMs are still working with the V-Model, despite the fact that you hear them talking about sprints, iterations, Scrum, XP programming. All these are actually implemented with small V runs and have little to nothing to do with agility.

The slow pace of development and release cycles in the automotive sector hinders the quick implementation of software fixes and feature enhancements.

This delay not only frustrates customers but also puts their safety at risk by keeping potentially critical issues unresolved for extended periods.

Lack of Consumer Education and Awareness

The general public’s understanding of cars as hardware running software is limited. First when TESLA became an important OEM, the entire world  started to understand how important software is in a car.

Immediately after has the automotive industry started to feel threatened by it and they started to invest more in software, more particularly, in improving the user experience of their cars.

If I make a comparison with the mobile phones in the early 2000, the TESLA is the iPhone while the other OEMs were Nokia and the others. We all know what happened to Nokia because they did not move faster.

Consumers must continue to push the OEMs to enhance the software of their cars, but this is a slow process, because the cars with good software are expensive, and people with money usually don’t look first at the software capabilities of their cars.

 

Inadequate Cybersecurity Measures

As cars become increasingly connected and autonomous, they become vulnerable to cyber threats.

Unfortunately, the automotive industry has been sluggish in implementing robust cybersecurity measures to protect vehicles from potential attacks.

Insufficient attention to software security leaves vehicles open to hacking, which can lead to unauthorized access, data breaches, or even physical harm.

The industry must prioritize cybersecurity and invest in proactive measures to safeguard vehicles and their occupants.

Because cybersecurity is hard to implement, very expensive and requires specialized personnel, no OEM was willing improving their cybersecurity.

This is the reason why the UNECE R155 requires now a Cybersecurity Management System (CSMS) audit in order to allow new vehicle types.

 

If you are an OEM or subcontractor (Tier 1-N) then you may want to know that Endpoint Cybersecurity is offering consulting on how to implement such a CSMS and make it auditable.

Lack of standards

Same as for computers, the IT industry started to exponentially increase only after there were good reasons to use computers. Only after the Internet became main stream have businesses, regular people and families started to buy computers.  So communication or inter-communication was and still is a main factor to buy hardware.

The same is happening with cars: people start to see the need for software in cars and now they start asking for better software. This can only happen if there is a market for software, but to create a market you need standards.

Android Auto and  Apple Car are standards that allow 3rd parties to create apps for the cars, but the offer is extremely small and not really relevant.

In my opinion, only when cars can exchange data either directly (Vehicle to Vehicle communication – V2V) or through some infrastructure (V2I) on a large scale will we see a significant increase in software demand.
Unfortunately, the lack of standards for communication between vehicles is making this process extremely slow.

 

Conclusion

The automotive industry’s failure to fully embrace the concept of cars as hardware running very complex software has far-reaching consequences on the long term.

By neglecting software development, cybersecurity, and collaboration with software experts, OEMs put customer safety and satisfaction at risk. Classical OEMs have started to see too late that better software means more sales and more satisfied customers and reacted too slow to find solutions.

The limited adoption of agile development processes and inadequate OTA update capabilities further hinder progress in this domain.

To address these challenges, the industry must prioritize software as an integral part of vehicle design and manufacturing, invest in cybersecurity measures, foster collaboration with software experts, and educate consumers about the software-driven nature of modern cars.

Only through a comprehensive and proactive approach can the automotive industry truly unlock the potential of cars as hardware running software.
