The significance of cyber security and its seven subdomains
Cyber security is the collection of strategies, technologies, and procedures used to secure the confidentiality, integrity, and availability of computer systems, networks, and data against cyber-attacks or unauthorized access. The primary goal of cyber security is to secure all corporate assets from external and internal threats and natural catastrophe interruptions.
Because organizational assets comprise several different systems, a successful and efficient cyber security posture necessitates coordinated actions across all of its information systems. As a result, cyber security is divided into the following subdomains:
Sub-domains of cyber security?
Out of many subdomains, the following seven are the most crucial:
- A security system for networks
Implementing both hardware and software techniques to secure the network and infrastructure against unwanted access, interruption, and abuse constitutes network security.
- A security approach to cloud computing
Cloud security is concerned with the creation of secure cloud infrastructures and applications for organizations that utilize various cloud service providers such as Amazon Web Services (AWS), Google, Azure, Rackspace, and others.
- Continuity plans and disaster recovery
DR&BC is concerned with procedures, monitoring, alerts, and strategies that assist businesses in preparing to keep business essential systems operational during and after any type of catastrophe, as well as restoring lost activities and systems following an incident.
- A secure approach to developing applications
Application security entails integrating numerous protections against a wide variety of threats within any software and services utilized within a business. To reduce the possibility of unauthorized access or alteration of application resources, it is necessary to design secure application architectures, write secure code, implement robust data input validation, threat modeling, and so on.
- The management of identities and the security of data
Identity management encompasses structures, procedures, and activities that enable valid persons to be authenticated and authorized to use information systems inside an organization. Implementing robust information storage techniques that assure data security at rest and in transit is part of data security.
- Educating the user
Formal training in computer security subjects is critical for boosting understanding of industry best practices, organizational processes, and regulations, as well as monitoring and reporting suspicious activity.
- The security of mobile devices
Mobile security refers to the protection of both organizational and personal information held on mobile devices such as cell phones, laptops, tablets, and so on against a variety of dangers such as unauthorized access, device loss or theft, malware, and so on.
Security challenges and the importance 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 thieves and evildoers, which is why it is critical to safeguard it with robust cyber security systems and processes.
The same rapidly changing technology world creates difficulties in executing effective cyber security plans. Furthermore, IT infrastructure develops, with many firms now transferring their on-premise systems to the cloud, introducing a whole new set of design and implementation difficulties, as well as a new category of vulnerabilities. Companies are ignorant of the different threats inside their IT infrastructure and, as a result, do not implement cyber security remedies until it is much too late.
