5.Ten types of cybersecurity
Many types of cybersecurity are employed to protect digital systems from malicious and
accidental threats. It is helpful to understand the ten most commonly referenced types of
cybersecurity.

1. Application security
   Application security prevents unauthorized access and use of applications and connected data.
   Because most vulnerabilities are introduced during the development and publishing stages,
   application security includes many types of cybersecurity solutions to help identify flaws
   during the design and development phases that could be exploited and alert teams so they can
   be fixed. Despite best efforts, flaws do slip through the cracks. Application security also helps
   protect against these vulnerabilities. A subset of application security is web application
   security. It focuses on protecting web applications, which are frequently targeted by cyber-
   attacks.


2. Cloud security
   Cloud security focuses on protecting cloud-based assets and services, including applications,
   data, and infrastructure. Most cloud security is managed as a shared responsibility between
   organizations and cloud service providers.
   15
   In this shared responsibility model, cloud service providers handle security for the cloud
   environment, and organizations secure what is in the cloud. Generally, the responsibilities are
   divided as shown below.


3. Critical infrastructure security
   Special security processes and types of cybersecurity solutions are used to protect the
   networks, applications, systems, and digital assets depended on by critical infrastructure
   organizations (e.g., communications, dams, energy, public sector, and transportation). Critical
   infrastructure has been more vulnerable to cyber-attacks that target legacy systems, such as
   SCADA (supervisory control and data acquisition) systems. While critical infrastructure
   organizations use many of the same types of cybersecurity as other subcategories, it is often
   deployed in different ways.


4. Data security
   A subset of information security, data security combines many types of cybersecurity solutions
   to protect the confidentiality, integrity, and availability of digital assets at rest (i.e., while being
   stored) and in motion (i.e., while being transmitted).


5. Endpoint security
   Desktops, laptops, mobile devices, servers, and other endpoints are the most common entry
   point for cyber-attacks. Endpoint security protects these devices and the data they house. It
   also encompasses other types of cybersecurity that are used to protect networks from
   cyberattacks that use endpoints as the point of entry.


6. IoT (Internet of Things) security
   IoT security seeks to minimize the vulnerabilities that these proliferating devices bring to
   organizations. It uses different types of cybersecurity to detect and classify them, segment
   them to limit network exposure, and seek to mitigate threats related to unpatched firmware and
   other related flaws.


7. Mobile security
   Mobile security encompasses types of cybersecurity used to protect mobile devices (e.g.,
   phones, tablets, and laptops) from unauthorized access and becoming an attack vector used to
   get into and move networks.


8. Network security
   Network security includes software and hardware solutions that protect against incidents that
   result in unauthorized access or service disruption. This includes monitoring and responding to
   risks that impact network software (e.g., operating systems and protocols) and hardware (e.g.,
   servers, clients, hubs, switches, bridges, peers, and connecting devices).
   The majority of cyber-attacks start over a network. Network cybersecurity is designed to
   monitor, detect, and respond to network-focused threats.


9. Operational security
   16
   Operational security covers many types of cybersecurity processes and technology used to
   protect sensitive systems and data by establishing protocols for access and monitoring to detect
   unusual behavior that could be a sign of malicious activity.


10. Zero trust
    The zero-trust security model replaces the traditional perimeter-focused approach of building
    walls around an organization’s critical assets and systems. There are several defining
    characteristics of the zero-trust approach, which leverages many types of cybersecurity.
    At its core, zero trust is based on several practices, including:
    Continuously verifying users’ identity
    Establishing and enforcing the principle of least privilege for access, granting only the access
    that is explicitly required for a user to perform a job and only for as long as that access is
    required
    Micro segmenting networks
    Trusting no users (i.e., internal or external)
    6.Many of the solutions within each of these types of cybersecurity are used across
    subcategories, such as:
    Anti-malware software
    Antivirus systems
    Backup
    Data loss prevention (DLP)
    Enterprise mobility management
    Encryption
    Endpoint detection and response (EDR)
    Enterprise mobility management (EMM)
    Firewalls
    Identity and access management (IAM)
    Intrusion detection and prevention system (IDPS)
    Mobile application management (MAM)
    Multi-factor authentication
    Network access control (NAC)
    Next-generation firewall (NGFW)
    Secure access service edge (SASE)
    Secure email gateways (SEG)
    Security information and event management (SIEM)
    17
    Security orchestration, automation, and response (SOAR)
    User and entity behavior analytics (UEBA)
    Virtual private networks (VPNs)
    Web application firewalls (WAFs)


11. Case studies about cybersecurity
    7.1 What Is Cyber Security Audit and How Is It Helpful for Your Business?
    When was the last time you performed your cybersecurity audit? An audit of complete
    cybersecurity management, not a simple scan. If it has been longer than you remember, then
    you are probably at risk of being a victim of cyberattacks. As the world becomes increasingly
    interconnected, the risk of cyberattacks escalates. To safeguard against these threats, it is
    essential to have a robust cybersecurity management system in place. Conducting periodic, in-
    depth cybersecurity audit is a vital part of this process.
    7.2 What is a Cybersecurity Audit?
    A cybersecurity audit involves a comprehensive analysis and review of your IT
    infrastructure. It detects vulnerabilities and threats, displaying weak links and high-risk
    practices. Significant benefits of IT security audits are:
    Risk assessment and vulnerability identification
    Strengthened security measures
    Compliance with regulations and standards
    Incident response preparedness
    Safeguarding sensitive data and customer trust
    Proactive threat detection and prevention
    7.3 How Prepared is Your Organization against Cybersecurity Risks?
    Recent studies and statistics highlight the growing severity of cyber risks to businesses. For
    example, according to a report by Cybersecurity Ventures, it is estimated that cybercrime will
    cost the global economy a staggering $10.5 trillion annually by 2025. This projection
    showcases the massive financial impact that businesses could face if they fail to address cyber
    risks effectively. It is not enough to simply have security plans; they require consistent
    auditing. When was the last revision made to your cyber risk management plans? Are your
    security documents regularly reviewed and adjusted to align with the specific requirements of
    each department? If you are unsure, then it is high time to do a cybersecurity audit. Top
    Indicators that you’re falling behind in your risk management:
    7.4 Out-of-date technology
    Being dependent on older technologies like old software, old hardware, outdated policies &
    practices, and outdated services can leave you vulnerable to emerging threats.
    18
    7.5 Risks flowing widely over opportunities
    You should experiment and innovate with new technologies. If you’re afraid of adopting
    new technologies with the concern that new tech will expose you to new threats, then it’s time
    to strengthen your security framework.
    7.6 Thinking your Business is “Too small” for cybersecurity Audit
    Do you believe that only large-scale companies require cybersecurity Audits? Think Again!
    Regardless of size, most companies are increasingly outsourcing services, enabling third
    parties to closely examine your critical systems and practices. Organizations of all sizes can
    benefit from a cybersecurity assessment. Cybersecurity is not just about technical resilience or
    IT security but about Information and Data Security. Misguided assurances from the internal
    team or a cybersecurity company and a false sense of security are the primary reasons hackers
    succeed in their attempts. They target your processes, people, procedures, and weakest links.
    7.7 The Scope of a Cybersecurity Audit
    Cybersecurity audits ensure a 360-degree in-depth audit of your organization’s security
    posture. They aim to identify vulnerabilities, risks, and threats that may affect the organization.
    These audits cover various areas, including:
    Data Security – involves reviewing network access control, encryption use, data security at
    rest, and transmissions.
    Operational Security – involves a review of security policies, procedures, and controls.
    Network Security – a review of network & security controls, anti-virus configurations, security
    monitoring capabilities, etc.
    System Security – This review covers hardening processes, patching processes, privileged
    account management, role-based access, etc.
    Physical Security – a review that covers disk encryption, role-based access controls, biometric
    data, multifactor authentication, etc.
    Beyond these, a cybersecurity audit can also cover cybersecurity risk management, cyber risk
    governance, training & awareness, legal, regulatory & contractual requirements, technical
    security controls, business continuity & incident management, and third-party management.
    7.8 Internal vs. External Cybersecurity Audit
    Cybersecurity audits can be conducted by either external cybersecurity services companies
    or internal teams. External cybersecurity audits are performed by experienced professionals
    from specialized companies. These professionals possess in-depth knowledge of security
    protocols and utilize advanced software and tools to conduct a comprehensive audit. Their
    expertise allows them to identify vulnerabilities and flaws in an organization’s cybersecurity
    risk management effectively. On the other hand, internal security audits are conducted by an
    organization’s in-house team. These audits can be performed more frequently and provide the
    advantage of having direct access to internal systems and processes. Internal auditors are
    familiar with the organization’s specific security requirements and can tailor the audit to
    19
    address its unique challenges. Both external and internal security audits offer distinct
    advantages and serve different purposes. Key points to consider include.
    7.9 External Security Audit:
    Independence: External auditors offer an unbiased assessment as they are not directly involved
    in the company’s day-to-day operations. Expertise and Experience: External auditors often
    have specialized knowledge and experience in conducting security audits across various
    industries. Compliance and Regulations: External audits help ensure compliance with industry
    regulations, standards, and legal requirements.
    Objectivity: External auditors objectively evaluate the company’s security controls without
    any internal bias or conflicts of interest. To get better value from the external security audit,
    you must find the right and affordable auditing company, set expectations for auditors, submit
    relevant and accurate information, and implement suggested changes.
    Despite the benefits of external audits, many organizations opt for internal cybersecurity audits
    due to their cost, efficiency, speed, and consistency.
    7.10 Internal Security Audit:
    In-depth Knowledge: Internal auditors have a better understanding of the company’s
    internal systems, processes, and culture, which allows for a more comprehensive assessment.
    Cost-effectiveness: Conducting internal audits can be more cost-effective since there is no
    need to engage external resources. Continuous Monitoring: Internal audits can be performed
    regularly, providing ongoing monitoring and evaluation of the organization’s security
    measures. Company-specific Focus: Internal audits can specifically address the company’s
    unique security challenges and requirement
