What are some of the sub-domains of cyber security?

Cyber security is defined as the collection of methodologies, technologies, and processes used to help safeguard the confidentiality, integrity, and availability of computer systems, networks, and data against cyber-attacks or unauthorised access. The primary goal of cyber security is to secure all corporate assets from both external and internal threats, as well as natural disaster disruptions.

Because organisational assets are comprised of numerous heterogeneous systems, an effective and efficient cyber security posture necessitates coordinated activities across all of its information systems. Lets know your business needs cyber experts then click on hire cyber security experts. As a result, cyber security is divided into the following subdomains:

What are some of the cyber security sub-domains?

Application Safety

Application security entails integrating numerous protections against a wide range of threats within any software and services utilised within a business. To reduce the likelihood of unauthorised access or alteration of application resources, secure application architectures must be designed, secure code must be written, rigorous data input validation must be implemented, threat modelling must be implemented, and so on.

Data Security and Identity Management

Identity management encompasses structures, processes, and activities that enable valid individuals to be authenticated and authorised to use information systems within an organisation. Data security includes using robust information storage mechanisms that ensure data security at rest and in transit.

Network Safety

Implementing both hardware and software techniques to safeguard the network and infrastructure from unwanted access, disruption, and misuse is what network security entails. Effective network security protects organisational assets from a variety of external and internal threats.

Mobile Security

Mobile security refers to the protection of both organisational and personal information held on mobile devices such as cell phones, laptops, tablets, and so on against a variety of dangers Unauthorized access, device loss or theft, virus, and so on are examples of such threats.

Cloud Security

Cloud security is concerned with the development of safe cloud infrastructures and applications for organisations that use various cloud service providers such as AWS, Google, Azure, Rackspace, and others. Protection against diverse dangers is ensured by effective design and environment setting.

Disaster recovery and business continuity planning (DR&BC)

DR&BC is concerned with processes, monitoring, alerts, and plans that assist organisations in preparing to keep business essential systems operational during and after any type of disaster, as well as restoring lost activities and systems following an incident.

User education

Formal training in computer security subjects is critical for boosting understanding of industry best practises, organisational procedures and regulations, as well as monitoring and reporting suspicious activity.

The importance and challenges of cyber security

Given the rapidly evolving technological landscape and the increasing adoption of software across various sectors such as finance, government, military, retail, hospitals, education, and energy, to name a few, more and more information is becoming digital and accessible through wireless and wired digital communication networks, as well as the ubiquitous internet. All of this extremely sensitive information is valuable to criminals and evildoers, which is why it is critical to safeguard it with strong cyber security systems and processes.

The importance of

  • good cyber security strategies
  • security breaches
  • at organisations such as
  • Equifax,
  • Yahoo,
  • and the United States Securities
  • and Exchange Commission (SEC),
  • which lost extremely sensitive user information,
  • causing irreparable damage to their finances and reputation.

And, as the pattern indicates, the rate of cyber-attacks is not slowing down. Every day, cybercriminals target businesses of all sizes in order to steal valuable information or disrupt services.

The same shifting technology landscape creates difficulties in executing effective cyber security tactics. When software is updated and upgraded, it continuously evolves, introducing new faults and vulnerabilities and opening it susceptible to various cyber-attacks. Furthermore, IT infrastructure evolves, with many firms now transferring their on-premise systems to the cloud, introducing a whole new set of design and implementation issues, as well as a new category of vulnerabilities. Companies are unaware of the different threats inside their IT infrastructure and, as a result, do not implement cyber security remedies until it is much too late.

Challenges for Cybersecurity

1. Adapting to a Remote Workforce

2. Emerging 5G Applications

3. Blockchain and Cryptocurrency Attacks

4.Internet of Things (IoT) Attacks

5. Phishing Scams

What is a cyber-attack?

A cyber-attack is an intentional attempt by external or internal threats or attackers to exploit and compromise the confidentiality, integrity, and availability of a target organization’s or individual’s information systems (s). Cyber-attackers employ illegal tactics, tools, and approaches in order to create damage and disruptions or obtain unauthorised access to computers, devices, networks, applications, and databases.

Cyber-attacks come in many forms, and the following list highlights some of the most common ones used by thieves and attackers to exploit software:

  1. Malware
  2. Ransomware
  3. Injection assaults (e.g., cross-site scripting, SQL injection, command injection)
  4. Session management and Man-in-the-Middle attacks
  5. Phishing
  6. Denial of service
  7. Privilege escalations
  8. Unpatched/Vulnerable software
  9. Remote code execution
  10. Brute force

What exactly is the distinction between a cyber-attack and a security breach?

A cyber-attack is not the same thing as a security breach. A cyber-attack, as defined above, is an attempt to compromise a system’s security. Attackers use several types of cyber-attacks, as described in the preceding section, to try to exploit the confidentiality, integrity, or availability of a software or network. In contrast, a security breach is a successful event or incident in which a cyber-attack results in the compromise of sensitive information, illegal access to IT systems, or service disruption.

Attackers continually attempt a wide range of cyber-attacks against their targets in the hope that one of them would result in a security breach. As a result, security breaches highlight another critical component of a comprehensive cyber security strategy: Business Continuity and Incident Response (BC-IR). BC-IR assists organisations in dealing with successful cyber-attacks. Business Continuity is concerned with keeping important business systems operational in the event of a security incident, whereas Incident Response is concerned with responding to a security breach and mitigating its impact, as well as supporting the recovery of IT and business systems.
