Understanding Cybersecurity

What is Cybersecurity?

Cybersecurity is the act of defending computers, servers, mobile phones, electronic devices, networks, and data from malicious actions by unauthorized users. It is a constantly evolving field and as a result a plethora of transgressing tactics are becoming commonplace, resulting in a defensive approach becoming a bare necessity.

The need for securing cyber systems has only increased with the surge in digitization of the economy, important services and relationships. At its core there are three  that strengthen one’s cybersecurity approach:

• Confidentiality: This principle tackles the issue of information security by ensuring that sensitive information is not shared with anyone without permission.
• Integrity: The integrity principle safeguards the reliability and accuracy of the shared data by ensuring no tampering is done to the data by unauthorized users.
• Availability: The processes undertaken to ensure that systems, as well as underlying data, remain functional and are reachable by authorized users whenever they need them.

It can be conclusively stated that these principles are in relation to the CIA triad.

Core Pillars of Cybersecurity

Cybersecurity is built on several key pillars that support the protection of systems, networks, and data. These pillars represent both the strategies and technologies used to safeguard digital infrastructure:

1. Network Security: Protecting devices and servers that facilitate interaction amongst several digital systems including LANs, WANs and the world wide web. Some of the integral components of this include firewalls, intrusion detection systems (IDS), and structured privately owned networks (VPNs).
2. Information Security: Extending more towards safeguarding and protecting data while enabling the same to remain confidential, integrated and above all available at all times. This is achieved by utilizing encryption, masking of data, and setting up controls on data access to ensure that sensitive information remains hidden from unauthorized users.
3. Application Security: Avoiding the creation of software apps that may have weaknesses which could be acquainted by attackers. Security of an application begins throughout its development, and such measures include routine repairs, secure coding policies, and regular audits of the code which minimizes the risks.
4. Endpoint Security: Safeguards gadgets including desktops, laptops, mobile phones as well as tablets. Given that these devices are a prime requirement for the cyber world, it is important to protect endpoint devices with anti-virus tools, encryption and secure passwords among other methods.
5. Identity and Access Management (IAM): It entails policies and technologies that ensure only approved users of a particular set of data or systems are able to gain access to them. This includes multi-factor authentication (MFA), single sign-on (SSO), and role-based access controls (RBAC).
6. Cloud Security: With the shift of business operations to the cloud, protection of cloud environments has turned out to be one of the main concerns. This encompasses data encryption, identity management, as well as secure application deployment into cloud environments.

Overall, these pillars present a holistic view of the issue of security and span multiple layers which protect against a wide range of possible attacks.

Section 3: A Brief History of Cybercrime with Relevant Case Studies

A Brief History of Cybercrime: Case Studies

Before engaging in the conversation about cybercrime and its history it is pivotal to have an understanding of the idea of cybercrime. In essence, cybercrime refers to the use of a computer or the internet to carry out an act which is deemed as illegal or prohibited. From this perspective it becomes evident that cybercrime can take many forms such as fraud, identity theft, online harassment, etc. With the turn of the century a new dimension was added to the scope of crime, whereas initially the technology was seen as a source of innovation, its purposes have now been distorted. To better in comprehend in the complex world of cyber crime the following case studies will be reviewed:

1. Targeting Americans Across Border: USA vs. Edward Snowden Case Study: A rather controversial political figure in modern politics Edward Snowden is an ex- National Security Agency contractor who leaked highly confidential documents revealing espionages carried out by the American government. Following the release of the documents Snowden fled away to Hong Kong and later to Russia claiming persecution by the American government. The relevance of this in the crime world lies in the fact that the documents released showcased the means by which a cybercriminal can reframe ones online presence to make it seem like a credible threat from one or a more countries.
2. Marooned in Canada: USA vs Alain Ghadiyani Case Study: Alain Ghadiyani is an Iranian national accused of engaging in illegal distribution, making and selling unlicensed drugs without a legal license. Unlike other case studies this has a much more traditional approach, Ghadiyani sought business by promoting drug trafficking and smuggling.
3. Hardcore Feminism: USA vs Janice Voss Case Study: A divorcee from Minnesota was evidently seen engaging in lesiusive contents for many entrainment firms, her case comes into the spot light after she claimed she was forced to do video filming of sexual acts which resulted in criminal and civil cases filed against hundreds of operators. She was also accused of mutilating and sexualizing herself in front of the camera. This also comes under cyber crime as hard core feminism could also be viewed as a movement started to fight for women’s rights to engage in graphic sexual activity.
4. Threats Related to Persistent Activity (APT’s): These ones are longterm spear phishing campaigns where an attacker can penetrate a network and remain undetected for a relatively longer time period. Most APT attacks are sponsored by the state and used for espionage or stealing of Intellectual Properties or sabotage.
5. DDoS (Distributed denial-of-service) Attacks: These insults attackers direct towards a targeted system include an immense amount of traffic overwhelming the system leading to either shutting of the system or making it inaccessible to bona fide users. DDoS attacks are mostly employed to disrupt the normal operations of businesses and even critical infrastructures, governmental authorities and agencies.
6. MitM (Man-in-the-middle) Attacks: In these bottom attackers, these bottom attackers sit hiding in the middle of two people who don’t know about their presence and blend in the chat going between those people and attempting to tamper with communications. This kind of attack is primarily observed with unprotected public wifi hackers, who intercept information sent from the user’s web browsers to the websites.
7. Insider Threats: Even when external actors are not in combination with aggression all the time, the threat is still potent to work against them or better said in turn comes from them. Insider threats more commonly come from the employees, contractors or business partners who seek wrongful ends by abusing access provision from the system and or the data in a negligent or malicious manner.

Cybersecurity: Threats on the perimeter

New and Emerging Threats: Today, the challenges for cybersecurity professionals have also exponentially increased due to new and emerging tools and methods being deployed by the cybercriminals to launch attacks in what is being referred to as an artificial intelligence and machine learning driven cybersecurity warfare.

• Machine Learning and Artificial Intelligence Enabled Cyberattacks: The use of AI in cyber warfare constitutes a long-standing concern for cybercrime experts. The automation that facilitates AI can be leveraged by attackers, for instance, to rapidly exploit system weaknesses that would formerly take weeks to uncover and execute an attack.
• Internet of Things Attack Surface: The emergence of connected IoT devices and other smart gadgets, such as connected cardio vascular units and smart lock devices, are becoming potential points of hacking. Most IoT devices don’t have strong security protection mechanisms and can thus be easily hijacked.
• Propelling Encryption Technology to the Next Level: Quantum computing is on the verge to becoming breakthrough technology as it sets to glimpse overt relations between security and quantum computers, however, quantum computers have the ability to decipher existing methods of encrypting data. Moreover, improvements are presently being worked on to strengthen encryption integrity, but in tandem quantum computing can extend to encompass new forms of cybersecrity as well as new threats.

Section 3: Cybersecurity Best Practices

Establishing and Maintaining a Secure Digital Environment

Equipping against digital threats needs a synergy of technology, compliant policies, and practiced conduct. Here are a few best practices to mitigate against cyber risks:

1. Use passwords with more digits: Passwords are still one of the primary requirements for verification. Construct passwords that do not match with anything else. The best passwords are a wash of letters, numbers, and special characters. Strongpassword can store the passwords as well as compose them.
2. Always use Multi-Factor Authentication (MFA): A Multi-Factor Authentication (MFA) enables the users to provide more than one verification in order to access an account. For example, something that you know (a password), something that you own (a smartphone or a hardware token), or something that you are (biometrics).
3. Always update your software: Cyber attacks usually target vulnerability in the systems installed with an outdated software. Updating software and patching them will help firms eliminate security risks early before they get exploited.
4. Frequent Training sessions to Employees: A human person is often the reason for any lapse in cyber security in the firm. Training employees regularly on the policies will help them detect phishing emails, understand the rules for dealing with sensitive information, and safe computing.
5. Encryption of data: This is critical because the information that is in transport or being stored cannot be decrypted without a suitable decryption key. As such customer details, financial information and business trade secrets must remain protected at all times.
6. Plans for Backup and Restoration: In case of a cyber attack such as ransomware, make certain that vital data is routinely copied for safekeeping and can be restored quickly. Such plans help limit the duration of loss of data and minimize the outage period.
7. Firewalls and Segmentation of Networks: They allow protection against further internal contaminations inside the organization’s networks. Firewalls provide the interface between trusted internal and outside networks, controlling the traffic passing through the networks.
8. Security of the Endpoints: This is essential as there is an assortment of devices used in the modern workplace, which include deployment of antivirus, enabling device encryption and ensuring that all endpoints are up to date through constant patching.

Section 4: The Role of Regulations and Cybersecurity Frameworks

Cyber Security Rules

As well as technological elements, more and more organizations are being made subject to cyber security legislations which have been established to safeguard

sensitive information. Adhering to such regulations not only assists with the protection of information but also ensures that the relevant organization is practicing best cybersecurity principles:

• Regulation on the Protection of Natural Persons: The Regulation on the Protection of Natural Persons Law Enforcement Policies generally imples strict terms on how any compliance and behaviors affecting the management of personal data must be handled. If not, then penalties for non-compliance exist. Due to its stringent guidelines, today’s post world has influenced the majority of data protection practices in a variety of regions sourcing from the regulation including every European Union member state and Canada.
• Health Insurance Portability and Accountability Act : HIPAA (Health Insurance Portability and Accountability Act) comes into action when there is a need to protect healthcare data in the United States which involves all health care providers and their associates to act in strict compliance with America’s organs bear cybersecurity protection guidelines to not compromise the privacy of patients.
• California Consumer Privacy Act: This is a law specific to reside in this state that concerning privacy of California residents and enhancing their control over their personal information while imposing duties on other businesses, not only assists in data security but compliments data ownership.

Cybersecurity Frameworks

To best manage the risks cyber threats pose against organizations, a number of structured models termed as cybersecurity frameworks can be of great assistance. Key frameworks include:

• NIST Cybersecurity Framework: This is Further developing by NIST Cybersecurity Group. Department of Commerce US. Many enterprises are using it in order to properly assess where they currently stand with their cyber security measures.
• ISO/IEC 27001: This is the internationally accepted standard that outlines how to implement an organized procedure to safeguard important company information.
• CIS Controls: These are CIS Controls and were established by the Center for Internet Security considering the risks associated with 21 primary cyber security threats and best practices to reduce any security risks.

Section 5: The Future of Cybersecurity

Emerging Technologies and Cybersecurity

The evolving landscape is such that the role of technology in the future of cybersecurity will play a pivotal role on how cyberattack strategies will shift in ensuring the new technologies are in fact being protected against the advanced threats.

• AI and Machine Learning: Undoubtedly the advancements that will be made by artificial intelligence and machine learning into cybersecurity are wide ranging, from enabling real-time response to a threat to fully automating it. Prior to cyber threats even emerging, AI is able to filter huge amounts of data, check for patterns and serve as a preventative measure.
• Zero Trust Model: A zero trust model assumes that every user or equipment that links to the network is misused. This model is centred on continuous verification and strong access control, which lowers the risks of internal and external threats.
• Blockchain: An area that has exciting potential in enhancing cybersecurity is the blockchain due to its distributed and immutable feature. It can serve in safely making transactions, in safely maintaining data, and in securely confirming one’s identity, thus making it difficulty for hackers to alter or grab information.
• Deficit of Cybersecurity Experts and Skills: The need for professionals in cybersecurity keeps on growing while the availability is limited. Various initiatives to close the cybersecurity skills gap through education, training programs, and certification courses will help with the enhancement of the digitally safe future in the primary countries.
